2Forum Ilmiah Diaspora Indonesia (FIDI)"Menuju 2045: Menyatukan Keunggulan Ilmiah Indonesia untuk
Bangsa yang Maju dan Berkelanjutan"

Pendahuluan
Pada tahun 2045, bangsa Indonesia akan memasuki usia kemerdekaannya yang ke-100. Pada saat itu
Indonesia diproyeksikan akan menjadi bangsa yang maju dan kuat atau dikenal dengan istilah Indonesia
Emas, salah satu faktor utamanya adalah penduduk Indonesia saat itu akan mengalami bonus demografi
dimana jumlah penduduk Indonesia sangat produktif, yaitu angkatan kerja (usia 15-64 tahun) lebih besar
dibandingkan penduduk yang tidak produktif (di bawah 5 tahun dan di atas 64 tahun). Oleh karena itu,
dibutuhkan sumber daya manusia (SDM) yang berkualitas dalam rangka menyongsong era tersebut.
Bangsa Indonesia diharapkan akan menjadi bangsa yang maju dalam berbagai bidang, baik sains dan
teknologi maupun ekonomi, serta mampu mengatasi berbagai permasalahan, baik kemiskinan maupun
ketertinggalan dalam bidang pendidikan. Namun demikian, untuk mencapai itu semua perlu diperhatikan
berbagai tantangan sekaligus peluang, sebagai dampak perubahan-perubahan di berbagai sektor
kehidupan, baik secara nasional maupun global.
Peluang yang bisa kita lakukan untuk mencapai cita-cita Indonesia Emas pada 2045 yaitu kolaborasi multistakeholder termasuk industri dan pendidikan untuk mempercepat dan mengkonsolidasikan perubahan
berkelanjutan baik dalam pola konsumsi maupun produksi. Kolaborasi pendidikan dan industri sangat
penting diperkuat dalam mewujudkan visi Indonesia Emas. Visi tersebut mesti tercapai pada 2045 untuk
menyongsong 100 tahun Indonesia merdeka.
Ikatan Ilmuwan Indonesia Internasional (I-4) sebagai organisasi nirlaba dengan lebih dari 3,000 anggotayang terdiri dari ilmuwan Indonesia dari seluruh dunia (~1,000 anggota diaspora). Keanggotaannya terdiri
dari beberapa jenjang: Anggota Muda (Pendidikan Terakhir: S1), Anggota Madya (S2) dan Anggota Prima(S3). ~40% dari anggota adalah Anggota Madya dan ~33% adalah Anggota Prima. Salah satu misi penting I-4
adalah pengembangan kolaborasi (antara ilmuwan diaspora dan ilmuwan di Indonesia) dan capacity building(antara mid-/senior- dan early-career researchers).
Acara daring yang diselenggarakan terutama di beberapa tahun terakhir selama pandemic, telah berhasil
meningkatkan jangkauan I-4, tetapi membangun jaringan (networking), menjajaki kolaborasi dan sinergi
dapat dimaksimalkan melalui kegiatan yang diselenggarakan secara luring.
Melalui kegiatan Forum Ilmiah Diaspora Indonesia (FIDI) atau Indonesian Diaspora Scientific Forum (IDSF)
yang diinisiasi oleh I-4 bekerjasama dengan Badan Riset dan Inovasi Nasional (BRIN), diharapkan menjadi
diskusi interaktif dan kolaboratif antara narasumber ahli dalam bidangnya dengan para peneliti Indonesia
baik dari dalam dan luar negeri, terutama mengenai cara membangun kolaborasi untuk Riset yang Inovatif
dan Produktif yang diperuntukkan bagi peneliti, staf pengajar, dan pelajar Indonesia, serta diharapkan bisa
menghasilkan luaran yang konkret untuk kemajuan riset dan publikasi ilmiah.

Comparative Study of Thermoelectric Properties of MoX2 (X =S, Se, Te) Using First Principle Calculation
We have done a comparative study on the thermoelectric properties of monolayer MoX2 (X = S, Se, Te). In thisresearch, we use density functional theory and Boltzmann transport equation to calculate electronic structure,
lattice thermal conductivity, and thermoelectric properties for each monolayer MoX2 material. This researchshows that all of the MoX2 materials is a direct semiconductor with varying bandgap. This research also reveals
that the X atom can affect the electronic structure, which will affect the thermoelectric properties of thesematerials. Furthermore, This research shows that MoSe2 has the highest thermoelectric power factor at 550 K
but surprisingly, MoTe2 has the highest ZT of 1.17 due to its poor lattice thermal conductivity.

Probing New Physics via Flavor-violating Processes
Massive neutrinos are the only conclusive evidence so far for the existence of a theory beyond the Standard
Model (SM). In spite of this, their origin remains unknown. Several models have been proposed, but testing
those are hampered by the tiny nature of neutrino masses, thought to be effects of new physics at high-energy
scale. Beside neutrino masses, new physics effects can appear as phenomena not predicted by the SM, such asa discovery of new Higgs along with the 125-GeV Higgs boson, flavor-violating type processes, and any
measurements that deviate significantly from SM values, to name a few. The latter is of particular interest due
to recent discrepancies found in muon anomalous magnetic moment and W-boson mass measurements.
The model to be discussed is a radiative mass model, in which neutrino masses are generated via higher-order
perturbative corrections. Such a mechanism allows more suppression factors, so the new physics scale could bewithin reach of ongoing experiments. However, introducing a neutrino mass model at, say TeV scale, which
exhibits large mixings, may also induce charged-lepton-flavor-violating (cLFV) processes. So far, none of theseprocesses are observed, and they are strongly constrained by data.
I will present a model of neutrino mass that can also induce such flavor-violating couplings, namely the Zeemodel. It is an extension of the two-Higgs-doublet model with a singly-charged boson. Neutrino masses arise
through these new particle exchanges at the one-loop level. Thanks to the symmetry of the model, flavorviolating decays will be induced, in particular the electron-muon type coupling whose signature was recently
reported by the CMS Collaboration. I would like to show the compatibility between this excess and neutrino
data, together with any other possible cLFV decays. Additionally, its ability to solve the muon g-2 and W-mass
problems will also be discussed.

Ratiometric Optical Oxygen Sensor Based on Perovskite Quantum Dots and Rh110 Embedded in An Ethyl
Cellulose Matrix
Ratiometric optical sensor gas sensing continues to develop optical sensing techniques and materials used invarious industrial and environmental applications. This research focuses on a new ratiometric optical sensor
using the development of new material of FAPbI3 perovskite QDs and a simple method to detect oxygen (O2)gas. FAPbI3 perovskite QDs are used as an indicator of oxygen gas, and rhodamine 110 (Rh 110) is a referencematerial in a ratiometric optical sensor. All of the sensing and reference materials are embedded in an ethyl
cellulose (EC) matrix and coated on the surface of the filter paper. Using a UV LED with a central wavelength of
380 nm as the excitation light source, the emission spectra results show that the emission wavelengths of theoxygen-sensitive dye (O2) FAPbI3 perovskite QDs do not overlap with the Rh 110 reference signal. Thus,
oxygen concentration can be measured using a ratiometric fluorescence reference-based approach. The
sensing signal will be obtained in the presence of analyte gas in the ratiometric sensitivity of R0/R100, whereR0 and R100 represent the luminescence intensity detected in 100% nitrogen and 100% oxygen
concentrations, respectively. The experimental results show the optical oxygen sensor’s sensitivity as R0/R100= 12.7. In addition, the response time and recovery of the oxygen gas sensor produced are 75 s and 93 s,
respectively. The use of a new type of FAPbI3 perovskite QDs material has been successfully developed in the
optical ratiometric sensor for oxygen gas. The sensor proposed in this study has a low cost and easy fabrication
process. The effect of spurious fluctuations in the excitation source intensity can be suppressed by theratiometric optical sensing method.

Shark-dust: Application of High-throughput DNA Sequencing of Processing Residues for Trade
Monitoring of Threatened Sharks and Rays
Illegal fishing, unregulated bycatch, and market demand for certain products (e.g. fins) are largely responsible
for the rapid global decline of shark and ray populations. Controlling trade of endangered species remains
difficult due to product variety, taxonomic ambiguity and trade complexity. The genetic tools traditionally used
to identify traded species typically target individual tissue samples, and are time-consuming and/or speciesspecific. Here, we performed high-throughput sequencing of trace DNA fragments retrieved from dust andscraps left behind by trade activities. We metabarcoded ‘shark-dust’ samples from seven processing plants inthe world’s biggest shark landing site (Java, Indonesia), and identified 61 shark and ray taxa (representing halfof all chondrichthyan orders), more than half of which could not be recovered from tissue samples collected inparallel from the same sites. Importantly, over 80% of shark-dust sequences were found to belong to CITESlisted species. We argue that this approach is likely to become a powerful and cost-effective monitoring tool
wherever wildlife is traded.

Diversity of Bacterial in Muara Gembong Estuary, Citarum River, West Java, Indonesia
Muara Gembong is a downstream region of the Citarum watershed that has runoff from anthropogenic
activities and has an impact on water pollution. In overcoming the problem of pollution, bacteria can be utilized
as a remediation agent. However, the information on the bacterial community structure in Muara Gembong isvery low. This study aims to identify the composition and bacteria profile of Muara Gembong waters with ametagenomic approach to the Next Generation Sequencing (NGS) method and determine the abundance ofwater parameters. Water samples taken at two stations with different characteristics were carried out in
October 2019. Sample processing and data analysis were conducted in October 2019–April 2020 at theLaboratory of Microbiology and Molecular Biotechnology, Faculty of Fisheries and Marine Science, Universitas
Padjadjaran and Novogene Singapore. Estuary water samples were enriched with a 0.2 nutrient broth medium
concentration. The NGS Novaseq Illumina method with variable regions V3 - V4 (341F and 806R) was used inthis research. The results identified 37 genera, 19 families, 13 orders, 7 classes, and 4 bacterial phyla, with thenumber of Operational Taxonomy Units (OTU) of samples for A1 being 49 and A2 being 48. The highest
abundance was obtained by the Gammaproteobacteria class (99.82%), which is dominated by the Vibrio
genera. The level of diversity is classified as medium with high dominance. The abundance and diversity
variability of the bacterial community at both stations are influenced by environmental conditions such as
water temperature, salinity, pH, DO, total nitrogen (TN), and total suspended solid (TSS).

Collaboration Work Between Japan and Indonesia on The Development of New Technology for Corrosion
Protection and Remote Monitoring for Bridge Structure
Corrosion of steel rebar in bridge structures is a growing issue worldwide. Repair technology against corrosion
damage in Indonesia uses common methods such as painting or patching repair. These methods are simple andeasy to apply to the damaged concrete structure. However, those methods cannot control rebar corrosion in
concrete, deterioration will occur again, and the engineer cannot monitor corrosion. Hence Indonesia needs
new enhancements in the corrosion repair methods and monitors the condition of the structure after repair.
Therefore, collaboration application research between Japan and Indonesia on corrosion protection for bridge
structures in Indonesia to solve that problems was carried out by employing sacrificial anode cathodic
protection as new corrosion repair technology namely Zinc Cartridge and a corrosion monitoring system basedon wireless information and communication technology by using Titanium Wire (Ti-Wire) Sensor. Transfer
technology from Japan to Indonesia in this collaboration work performed by experimental work in thelaboratory and actual work in the bridge structure. Local material was used and developed to support this newtechnology issue. Currently, the Zinc Cartridge and Ti-Wire Sensor were applied to three national bridges andone of the long-span bridges in Indonesia namely the Suramadu Bridge. From the reported work, it can beconcluded that Zinc Cartridge by using local material affords excellent to protect the steel bar in concrete
against corrosion, and Ti-Wire Sensor is reliable be used as a reference electrode to observe the repair
progress embedded in concrete and effectively transmits the real-time data of corrosion monitoring of rebar inconcrete by time dependency.

Handling Dynamic Worlds with Continual and Autonomous Machine Learning
Dynamic environments are one of the most challenging problems for deep learning (DL) where its fundamental
design principle lies in the i.i.d assumption between the training stage and the deployment stage. This problem
results in inaccurate predictions of DL because changes cause a deep model to be quickly outdated torepresent the current concept. My talk will start from the problem of evolving data streams which can be
regarded as a single non-stationary learning task. The evolving data stream problem suffers from drifting
distributions calling for a self-adaptive model, capable of quickly adapting from concept drifts. We will discuss
the cross-domain stream learning topic where a model is deployed in multiple streams suffering from the issueof domain shifts. After that, my talk will extend to the problem of continual learning where a model
encounters a sequence of different learning tasks. The goal is to master these tasks efficiently without thecatastrophic forgetting problem. Several advanced topics in continual learning will be covered in my talk.

Time has Come to Industrialize Transformation of Bio-based SiO2 into Si-based Chemicals
Silicon, mostly found as silica (SiO2) or silicates (Si2O32-), which is the most abundant element, comprisingmore than 40% of the earth’s crust, serves as primary sources for silicon polymers, photovoltaics, andchemicals. Based on BPS data, the annual production of rice husk (contained 85% of SiO2) in Indonesia achieves
15 million tons, which much exceeds from the silica world’s demand estimated to 1.5 million tons. It clearly
indicates that the natural SiO2 source from Indonesia possesses high potential to supply the silica needs.
High strength of the Si-O bond (100 kcal/mol) making the manipulative fashion into useful chemicals is of“grand challenge” for silicon chemist. Current industrial processes mostly start the SiO2 transformed to, so
called metallurgical grade Si (Si(MG), ca 86% purity), through carbothermal reduction carried out in 1900 oC-arc
furnace tools. This high-energy intensive process requires 10-11 kWh to produce one kilogram of Si(MG), withelectrically accounting for 40% of the total production cost. Indeed, this process is unfavorable for industrial
profit and environment. The Si(MG) is subsequently converted to various commodities including solar-grade
Si(SG) through Siemens or Union Carbide processes, Me2SiCl2 via Rochow-Muller process or alkoxysilane(TROS) production. Herein, the direct formation of silicon chemicals from silica through non-redox process ishighly desired.
The rational design to overcoming the conventional fashion should rely on the development of chemical
methods starting from renewable feedstock or abundant precursor. In this forum, the discussion will befocused on the development of how the SiO2 could be transformed in one-step process to the raw Si chemicals
including Si(SG), TROS, or SiCl4. Several insight including thermodynamic studies, density functional theory(DFT) calculation and technoeconomic assessments are provided to see the potential utility on industrial
application.

Characteristics of Durian Seeds Biochar at Different Pyrolysis Temperatures
Indonesia as an agricultural country produces and consumes a huge amount of fruits. One of the popular fruits
is durian (Durio zibethinus), which can create issues with the high amount of durian seeds. Durian seeds can befermented quickly. Thus, if they are not processed immediately, it causes pollution to the environment,
particularly an odor issue. One of the waste management is to convert durian seed waste into biochar, anameliorant agent to improve soil quality. This study aims to analyze the physicochemical properties of durian
seed-derived biochar under different pyrolysis temperatures. The results showed that the increases in thetemperature allowed the creation of more porosity in the biochars, which is due to chemical structure andcrystallinity arrangement. This is confirmed by the increases in surface area and total pore volume also
decreases in particle size. The change in the chemical structure can be verified by the decreases in the biochar
yield. The produced biochar from fruit seeds has excellent carbon content and elemental components such as
potassium, magnesium, phosphor, and sulfur, informing prospective fruit seeds as a soil amendment fertilizer.

Genomic Heterogeneity in Pancreatic Cancer Organoids and Its Stability with Culture
The establishment of patient-derived pancreatic cancer organoid culture in recent years creates an exciting
opportunity for researchers to perform a wide range of in vitro studies on a model that closely recapitulates
the tumor. One of the outstanding question in pancreatic cancer biology is the causes and consequences ofgenomic heterogeneity observed in the disease. However, to use pancreatic cancer organoids as a model tostudy genomic variations, we need to first understand the degree of genomic heterogeneity and its stability
within organoids. Here, we used single-cell whole-genome sequencing to investigate the genomic
heterogeneity of two independent pancreatic cancer organoid lines, as well as their genomic stability withextended culture. Clonal populations with similar copy number profiles were observed within the organoids,
and the proportion of these clones was shifted with extended culture, suggesting the growth advantage ofsome clones. However, sub-clonal genomic heterogeneity was also observed within each clonal population,
indicating the genomic instability of the pancreatic cancer cells themselves. Furthermore, our transcriptomic
analysis also revealed a positive correlation between copy number alterations and gene expression regulation,suggesting the "gene dosage" effect of these copy number alterations that translates to gene expression
regulation.

Investigating the Early Onset Colorectal Cancer
The incidence of young patients under 50 years old with colorectal cancer (CRC) is approximately three times
higher in Indonesia compared to Europe, the UK, and the USA. Typically, the development of sporadic
colorectal tumours could take up to 50 years (according to a mathematical model). However, it has been foundthat CRC in young patients may require some form of "accelerated carcinogenesis." This acceleration may occur
in the context of inherited diseases such as Lynch Syndrome (LS), although only around 15% of Early-Onset
Colorectal Cancers (EOCRC) are associated with known hereditary forms of the disease.
The aim of this study was to investigate the biology of EOCRC, focusing on the tumour phenotypes andmicroenvironment in permitting accelerated carcinogenesis. This study utilised a series of formalin-fixed,
paraffin-embedded (FFPE) tumour tissues EOCRC with grade and stage-matched late-onset colorectal cancer(LOCRC) in Indonesia and UK.
The results of this study showed:
A higher frequency of LS may contribute to a higher proportion of EOCRC cases in Indonesia. MSI CRC in
Indonesian CRC showed lower BRAF mutation and lower MLH1 methylation, yet higher KRAS and PIK3CA
mutations. Confirmation of the similarity of the majority of clinicopathology and some molecular features
between young and older CRC patients both in Indonesia and the UK. Confirmation that EOCRC is significantly
associated with signet ring cell tumours, metastasis, and CRC-related death. EOCRC shows higher expression ofgenes related to angiogenesis, interferon, MAPK, NFKb, hypoxia, apoptosis, matrix remodelling, andmetastasis.
Further studies will be directed to better understand the potential biological factors that may contribute to
the rise of EOCRC, such as epigenetic and microbiome landscape.

Hepatocyte Targeted Aptamer Nanoparticle Modification For Delivery of Angiotensinogen siRNA In vitro
The prevalence of hypertension worldwide has increased to reach 1.28 billion people in 2021 according toWHO. This increase was mainly due to an increase in hypertension risk factors in this population. Hypertension
in humans is a risk factor for stroke, heart attack, heart failure, arterial aneurysm and is the main cause ofchronic heart failure. Hypertension can be reduced by taking drugs regularly throughout the patient's life. In
taking hypertension drugs there are several side effects that can be experienced by hypertension sufferers.
These side effects include constipation, dizziness, fatigue, nausea and swelling of both legs. A more effective
breakthrough in hypertension treatment is needed, which means that sufferers do not need to take medication
every day and minimize drug side effects. More effective treatment of hypertension can be achieved with agenetic approach through the inhibition of specific gene expression. This genetic approach is known as RNA
interference (RNAi). Hypertension is closely related to blood pressure regulation carried out by the Renin
Angiotensin System (RAS). One of the RAS components that affect blood pressure is the protein
angiotensinogen. Angiotensinogen is produced in liver cells (hepatocytes) and is the only precursor ofangiotensin I (AGT I), which is one of the causes of increased blood pressure. Therefore, inhibition ofangiotensinogen gene expression in hepatocytes is expected to reduce the concentration of angiotensinogenprotein which will ultimately reduce blood pressure. In RNAi, siRNA (small interfering RNA) is used, which isdouble-stranded RNA of less than 30 base pairs and has 3 nucleotides hanging at both ends. The design of theangiotensinogen
siRNA
used
was:
5'UCGUCUUCCAGCACGACUUdTdT-3'(sense)and
3'dTdTAGCAGAAGGUCGUGCUGAA-5' (antisense) with a low homology angiotensinogen mRNA target: 5'UCGUCUUCCAGCACGACUU- 3'. The effectiveness of hypertension treatment can be increased by combining
angiotensinogen siRNA and modified aptamer nanoparticles to form chimeras. The absence of chimeric
aptamer- angiotensinogen siRNA synthesis with angiotensinogen mRNA targets in hepatocytes as analternative treatment for hypertension has prompted this research. Single-stranded RNA as an aptamer was
selected based on its affinity for RALA255-G10 cells (rat hepatocytes cell line) in vitro using the CellSystematic Evolution of Ligands by Exponential Enrichment (Cell-SELEX) method. In this study there were two
experimental groups. Group 1 was siRNA angiotensinogen-RNA chimera aptamer with naphtyl modificationand group 2 was the control group (siRNA angiotensinogen-RNA aptamer chimera without modification). Eachgroup consisted of 3 sequences taken based on the affinity of each candidate RNA aptamer for RALA255-G10
cells. The existence of a siRNA angiotensinogen-RNA aptamer chimera with naphtyl modification is expected tomake it easier for angiotensinogen siRNA to enter RALA255-G10 cells and inhibit their expression. Inhibited
expression of the angiotensinogen gene will lead to a decrease in the concentration of angiotensinogenprotein which in turn is expected to viii cause a decrease in blood pressure.

Wajah Janus Bilirubin: Dari Toksisitas Neonatal Hingga Potensi Perlindungan pada Penyakit
Neurodegeneratif
Bilirubin tak terkonjugasi (unconjugated bilirubin, UCB) adalah metabolit katabolisme heme dan memiliki wajah
Janus karena memiliki efek neurotoksisitas dan neuroprotektif. UCB dapat menyebabkan neurotoksisitas padaneonatus (kernikterus) dan menyebabkan gangguan neurologis dan kematian sebagai konsekuensinya. Sebagai
pendekatan alternatif untuk fototerapi atau transfusi tukar yang merupakan pengobatan standar untuk
neonatal hiperbilirubinemia, kami menguji kurkumin (curcumin, Curc). Kami menggunakan tikus Gunn sebagai
model kernikterus. Curc memberikan perlindung penuh dari hipoplasia serebelar (tanda toksisitas bilirubinpada model hewan kernikterus) yang ditandai dengan normalisasi berat, jumlah sel dan lapisan arsitektur
cerebellum dan pemulihan kemampuan koordinasi motorik. Kami menemukan peradangan (termasuk kadar
mRNA dan protein TNF-α), ketidakseimbangan redoks, dan neurotoksisitas glutamat di antara mekanisme
molekuler yang dinormalisasi oleh Curc. Kemampuannya untuk mencegah kerusakan tanpa menurunkan kadar
serum bilirubin menunjukkan efek langsung Curc pada mekanisme kerusakan di otak. Hasil studi ini
menunjukkan potensi Curc dalam skenario klinis, terutama dalam keadaan di mana fototerapi dan transfusi
tukar tidak dapat dilakukan.
Wajah kedua dari bilirubin yang dieksplor dalam proyek kami adalah potensi neuroprotektifnya. Peningkatan
level bilirubin yang ringan (contoh populasi sindrom Gilbert), terbukti memberi perlindungan dari berbagai
penyakit seperti penyakit kardiovaskular, diabetes, kanker, multiple sclerosis dan glioma. Namun, peran UCB
masih belum diketahui pada penyakit Parkinson (Parkinson’s disease, PD) yang merupakan gangguan
neurologis dengan pertumbuhan tercepat dan belum memiliki terapi modifikasi. Berdasarkan latar belakangini, potensi terapi UCB pada PD diuji. Efek neuroprotektif dari UCB konsentrasi rendah ( 0,5-4 µM) diinvestigasi
dalam model PD (kultur organotipik dari substansia nigra) yang diinduksi dengan rotenone (Rot) dosis rendah.
UCB 0,5 dan 1 µM sepenuhnya melindungi dari hilangnya neuron TH+ (neuron dopaminergik, DOPAn).
Peradangan, khususnya tumor necrosis factor alpha (TNF-α), ditemukan sebagai kunci perlindungan UCB
terhadap DOPAn. Studi lebih lanjut diperlukan untuk penggunaan UCB di klinik, tetapi TNF-α mungkinmemainkan peran kunci dalam merancang pilihan terapi untuk PD.

Non-Pathogenic Microbiome as Potential Biocontrol Agents for Vector-Borne Viral Diseases
About 75% of emerging infectious diseases are zoonotic in origin, which in turn represent zoonotic diseases(zoonoses) as a threat to global health. Zoonoses involve both animals and humans and are caused bypathogens such as viruses and may be transmitted through arthropod vectors. Some examples of vector-borne
viral zoonoses (VBVZ) include La Crosse encephalitis (family Peribunyaviridae), Japanese encephalitis(Flaviviridae), and Chikungunya (Togaviridae) are all zoonotic and mosquito-borne. Global environmental andsocioeconomic changes by human activities may have facilitated the emergence and re-emergence of
vectorborne zoonoses in the world, for example by accidental imports of mosquitoes due to international
human movements and sudden turns of sylvatic cycle of viral zoonoses due to disruptions of wildlife habitat. In
order to prevent future emergence of vector-borne viral zoonoses, multisectoral collaboration andinterdisciplinary partnerships, including environment, wildlife, and entomological sectors will be very much
required.
With the absence of treatment and vaccine available for most vector-borne viral diseases, added with
gradually-ineffective insecticides currently used to control the vectors, there is an urgency to find new
approaches to control the disease circulation. Biological control (biocontrol) efforts have long been suggested
as a promising strategy, however, this requires an in-depth look at the vectors’ microbiome and interactions
between the host, pathogens, and the non-pathogenic components harbored by the mosquitoes. Nonpathogenic insect-specific viruses (ISVs) have the potential to serve as biocontrol agents since they could not
replicate in mammalian cells and have been indicated to modulate pathogenic viruses. Our studies showed thateach mosquito species seems to have a diverse set of viruses (most of which are ISVs) and they might haveimportant implications for the presence of vector-borne (pathogenic) viruses or otherwise. The ability of ISV in
impacting pathogenic virus’ infection in mosquitoes and further effect the disease spread deserves to be
explored.

Saatnya Kita Memanen Listrik dari Laut
Suatu kehormatan Presiden Joko Widodo menjadi presiden G-20 dan kesempatan emas bagi Indonesia
menunjukkan kita serius melakukan peralihan energi dari minyak bumi dan batu bara ke energi terbarukan,
sesuai tujuan untuk mencapai nol emisi pada 2060. Bahkan, negara menargetkan, 23 persen kebutuhan energi
dipenuhi energi terbarukan pada 2025. Memasuki akhir 2022, pencapaian energi baru dan terbarukan (EBT)baru 12 persen. Karena itu, kita harus melakukan lompatan dan investasi besar-besaran.
Dengan adanya kesepakatan Joint Energy Transition Partnership (JETP), salah satu hasil pertemuan G-20 padaNovember 2022 sudah saatnya kita membangun EBT dari laut. Syarat utama energi alternatif terbarukan
adalah ramah lingkungan dan tahan perubahan iklim jangka panjang. Tak kalah penting, sebaiknya sesuai
kelimpahan sumber daya lokal. Sumber EBT laut bisa dari gelombang laut, tinggi pasang surut, perbedaan suhu
permukaan & dasar laut, dan arus laut. Dari ke-empat sumber ini yang paling potensi untuk dikembangkan
adalah arus dan gelombang laut. Gabungan Arus lintas Indonesia (Arlindo) dan arus pasang surut sangat ideal
sebagai sumber efektif untuk dikonversikan menjadi energi listrik. Selama masih ada matahari dan bulan, arus
pasut selalu ada. Karena itu, arus laut ideal untuk sumber listrik karena bisa diprediksi, selalu ada, ramah
lingkungan, dan sesuai kearifan lokal sebagai sumber daya laut yang melimpah.
Banyak selat-selat sempit kita yang mempunyai arus laut sangat besar > 2.5 meter/detik, yang ideal untuk
dibangun Pusat Listrik Tenaga Arus Laut (PTAL). Teknologi untuk mewujudkan energi dari laut ini sudah ada
dan bisa diterapkan di Indonesia. Berbagai jenis teknologi turbin untuk EBT laut yang bisa kembangkan sesuai
dengan kondisi selat. Bahkan bisa dibangun “turbin farm” artinya banyak turbin di satu selat.
Dengan dibangunnya prototipe PTAL akan menggugah insinyur kita untuk menguasai teknologi dan universitas
akan mengembangkan kurikulum bidang ini. Pusat energi terbarukan dari laut akan menjadi laboratorium riset
dalam pengembangan teknologi ini dan daya tarik mahasiswa asing untuk kuliah di universitas kita sehingga
bisa menaikkan peringkat universitas di kancah internasional.
Karena arus laut, sumbernya jelas tersedia dan melimpah, tinggal mengambil. Ibarat mau panen padinya sudahtersedia di sawah, siap dipanen dan teknologi untuk memanennya sudah ada. Maka, saatnya kita memanen
listrik dari laut.

Pengembangan Reaktor Nuklir Generasi IV Skala Kecil berbasis High-Temperature Gas-Cooled Reactor(HTGR)
Pembangkit listrik dari energi nuklir merupakan salah satu jenis pembangkit listrik yang berperan sebagai
baseload yang tidak menghasilkan gas emisi CO2. Oleh karena itu, pemanfaatan energi nuklir menjadi salahsatu kunci dalam terwujudnya net-zero emission di tahun 2060. Disisi lain, pengembangan energi nuklir dengan
daya besar (diatas 1000 MW) mengalami hambatan dari segi biaya (capital cost) dan waktu pembangunan.
Karenanya, kecenderungan pengembangan energi nuklir saat ini mengarah kepada energi nuklir berdaya kecilmenengah atau yang dikenal dengan small modular reactors (SMRs). Generation IV International Forum (GIF)
yang merupakan forum internasional dalam pengembangan advanced nuclear reactor bekerjasama dengan
berbagai pihak terkait dalam mendesain reaktor nuklir generasi IV berskala SMRs. High-Temperature GasCooled Reactors (HTGRs) adalah salah satu tipe reaktor nuklir generasi IV yang paling potensial untuk
dikembangkan secara komersial. Salah satu keunggulan HTGR adalah kemampuannya dalam menghasilkan uap
panas bersuhu tinggi hingga 1.000 °C. Saat ini Jepang telah mengoperasikan reaktor HTTR yang merupakan
reaktor riset bertipe HTGR dengan tujuan utamanya memanfaatkan uap panas dari reaktor nuklir untuk
memproduksi hidrogen. HTTR yang beroperasi saat ini didesain dengan tujuan utama agar mampu
menghasilkan uap panas dengan suhu maksimum sebesar 950 °C agar dapat dimanfaatkan untuk produksi
hidrogen. Akan tetapi, desain reaktor ini masih cukup kompleks terutama dalam penyusunan komposisi bahan
bakar di dalam reaktor. Kompleksitas susunan bahan bakar ini bertujuan agar temperatur di dalam reaktor
tidak melebihi ambang batas aman yaitu 1.200 °C. Dengan komposisi bahan bakar yang telah dioptimalkan
tersebut, nilai maksimal burnup yang dihasilkan sebesar 33 GWd/t. Penelitian kami mengenai HTGR di
Department of Applied Physics and Nuclear Engineering, Kyushu University fokus dalam mendesain HTGR
berskala SMRs dari sisi neutronic dan keamanan (safety) agar mampu menghasilkan nilai burnup tinggi hingga
100 GWd/t sehingga penggunaan bahan bakar lebih optimal dan mampu beroperasi dalam jangka waktu yanglama tanpa perlu melakukan penggantian bahan bakar.

High Energy Density Asymmetric Supercapacitors Enabled by La-induced Defective MnO2 and Biomassderived Activated Carbon
This study reports a high energy density asymmetric supercapacitor enabled by La-induced defective MnO2
and biomass-derived activated carbon. Our findings reveal that the incorporation of La ions enhances the
conductivity of α-MnO2, resulting from a significant increase in lattice defects that provide a greater redox
active surface area. In the three-electrode system, the synthesized La-doped MnO2 and activated carbon fromempty palm bunches (AC-EPB) achieved a maximum capacity of 202 F g−1 and 178 F g−1 at 0.5 A g−1,
respectively. In the assembled La0.2Mn0.8O2 //AC-EPB asymmetric supercapacitor, we achieved an
outstanding energy density of 32.8 Wh Kg−1 at a power density of 4500 Wh Kg−1 while maintaining 97.2% of
initial capacity after 5,000 cycles. This research provides new insights into the preparation of defective
pseudocapacitive materials by rare-earth metal for energy storage applications.

Enhancing Energy Efficiency in Freezers Using Dry Ice Gel-Based Phase Change Materials: A Step towards
Sustainable Household Electricity Consumption
The increasing population growth in cities is causing environmental detriments, including global warming andozone depletion. Moreover, the demand for electrical energy in Indonesia is rapidly rising, leading to a yearly
increase of approximately 1.3% in carbon dioxide gas emissions, further exacerbating environmental damage.
The household sector accounts for higher electricity usage compared to industry and transportation, withprojected increases from 49% in 2018 to 58% in the BAU scenario and 61% in the RK scenario by 2050. Coolingequipment, such as air conditioners, refrigerators, and freezers, is the primary contributor to high householdenergy consumption. This study proposes a method to enhance the energy efficiency of freezers by utilizing
phase change materials, specifically dry ice gel. While previous studies focused on the impact of the position ofphase change materials on freezer wall temperature, this research introduces a detailed methodology ofmeasurement and examines the influence of dry ice gel-based phase change material on wall temperature
variance using descriptive statistical analysis. The wall temperature of the freezer was measured using T-type
thermocouples and the ADAM 6018+ data logger. The results demonstrate that the sensor thermocouples
were verified against calibrated thermometers, yielding an R2 value of 0.99. By incorporating dry ice gel-based
phase change material, the freezer maintained a temperature within the range of 1-2°C during 4, 6, and 8 hours
of non-operation. These findings contribute to the exploration of various phase change materials and their
combinations, aiding in the improvement of freezer efficiency. Future studies will extend this investigation toencompass different types of phase change materials to enhance the energy efficiency of not only freezers but
also other cooling equipment like air conditioners and refrigerators.

Carbon-Free Energy Systems Toward the Realization of Zero Carbon Society in Indonesia
Energy transition toward the creation of sustainable and clean energy systems is currently performed by every
country in the world. Energy sustainability includes three main pillars of energy security, energy equity, andenvironmental sustainability. Energy security deals strongly with the capacity and capability to provide therequired energy in terms of quantity and quality. Moreover, energy equity is expected to broaden theopportunity to mutually participate, including economic aspect, to all the stakeholders. Finally, theenvironmental sustainability covers the highly-balanced and maintained environmental conditions, including
air, water, soil, and food. This kind of clean and sustainable energy systems are constructed by several
technologies, including decarbonization, mutual utilization of non-carbon based fuels, big data, forecasting,communication, smart grid, and open market. In addition, a broad adoption of digital twin technology isbelieved to be able to efficiently integrate, accurately predict, and visualize the whole energy systems,
accelerating the realization of clean and sustainable energy systems.

Photoelectrochemical Green Hydrogen Production
The generation of green hydrogen using sunlight offers a carbon-neutral route to meet the ever-increasing
world’s energy needs. In recent years, significant progress has been reported, especially inphotoelectrochemical water splitting, but two major challenges remain. First, although solar-to-hydrogen (STH)
efficiency as high as 30% has been demonstrated, the use of expensive and non-scalable III-V semiconductors is
required. On the other hand, low-cost metal-oxide based devices, using mainly BiVO4 as the absorber, have
only achieved STH efficiency of less than 10%, due to the limited absorption of BiVO4. Novel metal oxide
semiconductors with a more favorable bandgap, which are stable and efficient, are therefore desired. The
second challenge is related to the scale-up of the devices, from laboratory experiments to large-area device
demonstrations. Several efforts exist, but the performance of the large-area devices is still significantly smaller(up to a factor of 5) as compared to the small-area equivalent. In this talk, the principle of solar water splitting
devices to generate green hydrogen, both from the material requirements and the device architecture’s pointof-view will be elaborated, and our research efforts in developing novel low-cost metal oxide photoelectrodes
and mitigating scale-up related losses in solar water splitting devices will be presented. Based on thesefindings, a novel concept that would allow moderately performing oxide-based devices to be energetically andeconomically competitive will be presented. Finally, the prospects of photoelectrochemical hydrogenproduction in Indonesia will be discussed.

Insights from Defects in Zirconia-Based Cathodes in Fuel Cells for Sustainable Energy Solutions
Proton exchange membrane fuel cells (PEMFCs) are promising energy conversion devices for hydrogen-based
applications. The oxygen reduction reaction (ORR) at the cathode is a key step, typically facilitated by
expensive and limited Pt-based catalysts. To overcome these limitations, low-cost and efficient ORR catalysts,
such as zirconia, are sought. Zirconia-based catalysts can achieve stability in acidic environments and be
optimized through heat treatment and oxygen control. Defects, such as oxygen vacancies and nitrogen doping,play a crucial role in modifying the ORR catalytic activity. However, the specific roles of these defects inzirconia-based catalysts remain unclear. We employed density functional theory to investigate the ORR
mechanisms on the tetragonal zirconia (101) surface and the influence of the defects. We aim to understandthe impact of defects on the ORR catalytic activity and explore deviations from "universal scaling" observed invarious catalysts. Surprisingly, defects play a minor role in enhancing the ORR activity, with energy barriers
comparable to the pristine surface. However, an increase in the ORR current suggests alternative factors atplay. The findings contribute to the development of efficient and cost-effective catalysts for PEMFCs. Alignedwith the theme "Pathways to 2045: Uniting Indonesian Scientific Excellence for a Developed and Sustainable
Nation," the insights from this research are expected to contribute to Indonesia's pursuit of sustainable energy
solutions, offering guidance for the design of efficient and cost-effective electrocatalysts crucial for achieving
sustainable and commercially viable proton exchange membrane fuel cells.

Formation of Iron Oxide/Iron Rich Nanoparticle with Superior Catalytic Activity for Visible Light Assisted
Fenton Reaction Induced by Organic Acid Addition in Hydrothermal Synthesis
Advanced oxidation processes are among the technologies for degradation of pollutants especially toxic andnon-biodegradable organic pollutants such as dyes and spent resin. Visible light assisted Fenton reaction is oneof the preferred reactions for producing highly reactive hydroxyl radical for oxidation of the pollutant.
Inexpensive and non-toxic iron oxide is a very well-known catalyst for facilitating photo Fenton reaction.
Research on iron oxide nanoparticle synthesis has been robustly developed since some decades ago with themain objective to increase the catalytic activity by modifying the physicochemical properties through variationof synthesis procedure, substitution of iron with other transition metals etc. The solvent, nucleating agent, andstabilizer have been reported to affect the size and phase of iron oxide nanoparticle produced byhydrothermal synthesis method. The beneficial effect of organic acid such as citric acid has been reported toenhance the Fenton reaction by zero valent iron. In our study, the acetic acid, citric acid and EDTA addition for
producing iron oxide with NH4HCO3 as nucleating agent produced iron oxide nanoparticle with different
phase namely Akaganeite (β-FeOOH,Cl), Lepidocrocite (γ-FeOOH) and Goethite (α-FeOOH), respectively. The
particle size of the produced iron oxide is much different between these three procedures, acetic acid addition
produced β-FeOOH,Cl with particle size around 50~100 nm, citric acid addition produced γ-FeOOH with size
particle less than 5 nm and EDTA addition produced α-FeOOH with size particle around less than 50 nm. The
coexistence of minor iron rich particles with iron oxide was observed in the case of γ-FeOOH and α-FeOOH.
Iron rich/ Goethite composite has three times faster catalytic activity (Kapp: 0.026 min-1) for degradation of
methylene blue than that of Akaganeite (Kapp: 0.008 min-1), Iron rich/Lepidocrocite composite catalytic
activity (Kapp: 0.22 min-1) was ten times faster than that of Goethite. The superior catalytic activity of Iron
rich/lepidocrocite composite was dominantly contributed by photo assisted Fenton reaction facilitated by ultra
nano γ-FeOOH. The citric acid probably functioned to stabilize the iron oxide nanoparticle and to form ironcitrate complex that was involved in the production of hydroxyl radical. Fenton reaction facilitated by iron richparticle slightly contributed to the increase in the reaction rate.

Eradicating HIV/AIDS Through Gene Editing
The innovation of CRISPR-Cas9 has single-handedly revolutionized biotechnology by enabling efficient andspecific cutting of DNA. CRISPR-Cas9 approaches are promising to target not only the human genome but also
the DNA of pathogenic viruses, which coincidentally is the canonical function in its bacterial origin. A myriad ofstudies in the past decade has proven the efficacy of CRISPR-Cas9 treatment to cleave viral DNA intermediates
in vitro. One of the most widely targeted is the proviral genome of human immunodeficiency virus type-1 (HIV1). The disease burden of HIV-1 is massive—the infection is incurable and has remained a pandemic for overfour decades. Integrated HIV-1 provirus inside the human genome causes viral persistence inside latent cellularreservoirs, eluding antiretroviral therapy (ART) and sterilizing cure. Specific targeting and disruption of theHIV-1 proviral genome are necessary to achieve viral clearance, which can be achieved with CRISPR-Cas9. Here,
we review the features and up-to-date evidence of CRISPR-Cas9 to target the HIV-1 proviral genome andsuppress viral replication. We will also discuss potential CRISPR/Cas9 delivery methods in vivo, in combination
with other gene editing modalities and other therapeutic approaches, to bring gene editing-based HIV-1 cure
closer into clinical use.

Exploiting Antigen Presentation Pathways for Precision Immune Engineering
Current treatments for autoimmunity rely on general immunosuppression, which exposes patients toopportunistic infections. Hence, immunoregulatory modalities, which educate the immune system to induce
antigen-specific tolerance are desirable. My doctoral research revolved around engineered red blood cells(RBCs) to treat preclinical models of autoimmune diseases by hijacking the tolerogenic RBC clearance
pathways. As a postdoctoral fellow, I worked on an alpaca-derived single domain antibody fragment(nanobody)-based platform. I have engineered these nanobodies to efficiently target antigen presenting cells
and transmit either tolerogenic or vaccinal signal to antigen-specific immune cells. I showed that a single doseof a VHH that recognizes major histocompatibility complex class II/MHCII (VHH MHCII), conjugated to a myelin
peptide and an anti-inflammatory corticosteroid, i.e., dexamethasone (VHH MHCII-MOG-DEX), affords lasting
protection in a mouse model of multiple sclerosis (MS). A single dose of VHH MHCII-MOG-DEX also reverses
paralyses in mice without compromising the capacity of the immune system to fight pathogens. I further
developed this technology for treating type 1 diabetes and as a SARS-CoV-2 vaccine. My independent group at
the Division of Immunology, Boston Children’s Hospital/Harvard Medical School (opening 1 January 2024) willaspire to produce novel treatments for autoimmune and infectious diseases.

Role of Lowered Level of Serum Vitamin D on Diabetic Foot Ulcer and Its Possible Pathomechanism: A
Systematic Review, Meta-Analysis, and Meta-Regression
Background: Diabetic foot ulcer (DFU) is responsible for multiple cases of lower extremity amputation among
diabetic patients. Many studies have suggested the possible inverse correlation between DFU development
and serum vitamin D (SVD) level.
Objective: To investigate the association between SVD level and DFU development and to emphasize theinvolved pathomechanism.
Methods: A digital search was performed on 8 major databases and 4 preprint databases using pre-planned
keyword combinations for literature published until 10 March 2023. The protocol has been registered on
PROSPERO (CRD42023415744). Original research papers reporting the SVD level of DFU and non-DFU patientswere included. The selection for the included records followed Preferred Reporting Items for Systematic
Reviews and Meta-Analyses (PRISMA). Meta-analyses using random effect were performed and the data were
presented as standardized mean difference (SMD) and 95% confidence interval (CI). The value of I 2 was usedas the heterogeneity parameter. Meta-regression was performed to identify factors contributing to theheterogeneity in the pooled analysis.
Results: Twenty-one studies were included in the meta-analysis with a total number of patients reaching 9,570(n=2,592 and 6978 for DFU and non-DFU groups, respectively). Of which, as many as 18 studies were included in
the meta-analysis. It was revealed that the SDV level is significantly lower in DFU group (p-total=0.0037; SMD=
-1.2758; [95% CI: -2.0786 to -0.4730]). The heterogeneity was considerably high with I 2 = 99.27%. Based on themeta-regression, age, study location (based on the continent), and total cholesterol level were the associatedfactor for the heterogeneity (p&lt;0.01). In the pooled analysis, inflammatory markers such as serum levels of
CRP (n=4), ESR (n=3), IL-6 (n=3), and IL-8 (n=2) were found significantly higher in DFU group at p&lt;0.01.
Conclusion: Lowered SVD level is associated with DFU, where the pathomechanism for this relationship might
involve inflammation and infection susceptibility.

Randomly Incorporated Genomic N6‐Methyldeoxyadenosine Delays Zygotic Transcription Initiation in A
CnidarianN6-methyldeoxyadenosine (6mA) is a chemical alteration of DNA, observed across all realms of life. Although
the functions of 6mA are well understood in bacteria and protists, its roles in animal genomes have been
controversial. We show that 6mA randomly accumulates in early embryos of the cnidarian Hydractinia
symbiolongicarpus, with a peak at the 16-cell stage followed by clearance to background levels two cell cycles
later, at the 64-cell stage—the embryonic stage at which zygotic genome activation occurs in this animal.
Knocking down Alkbh1, a putative initiator of animal 6mA clearance, resulted in higher levels of 6mA at the 64cell stage and a delay in the initiation of zygotic transcription. Our data are consistent with 6mA originatingfrom recycled nucleotides of degraded m6A-marked maternal RNA postfertilization. Therefore, while 6mA
does not function as an epigenetic mark in Hydractinia, its random incorporation into the early embryonicgenome inhibits transcription. In turn, Alkbh1 functions as a genomic 6mA “cleaner,” facilitating timely zygotic
genome activation. Given the random nature of genomic 6mA accumulation and its ability to interfere withgene expression, defects in 6mA clearance may represent a hitherto unknown cause of various pathologies.

Intelligence - AI) dapat dijalankan di atas perangkat komputasi modern dengan biaya yang dapat dijangkau oleh
organisasi publik. Hal ini membuka peluang penggunaan AI dalam bidang kesehatan dan rehabilitasi. Dengan
makin banyaknya data kesehatan yang tersentralisasi di Indonesia, AI dapat menjadi solusi teknologi digitalyang dapat membantu berbagai pihak yang berkepentingan di kesehatan. AI dapat membantu memilah data
imaging/radiologi, mensintesis dan menggambarkan data rekam medis digital, bahkan dengan menggunakanmodel bahasa besar (Large Language Model – LLM), dapat juga mendukung dan membantu pasien dan
keluarga pasien dalam menangani kondisi kesehatan yang mereka miliki.
Presentasi ini bertujuan untuk memaparkan penelitian penggunaan AI untuk kesehatan di US oleh peneliti
diaspora Indonesia di University of Pittsburgh, US. Berkolaborasi dengan pakar dan praktisi kesehatan, peneliti
diaspora Indonesia di University of Pittsburgh membangun infrastruktur teknologi kesehatan digital dengan
menggunakan teknologi komputasi mobile, piranti elektronik yang dapat dipakai, teknologi seluler, dan
teknologi intelejensia buatan untuk menangani berbagai kasus kesehatan kronis dan disabilitas. Tiga solusi
kesehatan digital akan disorot dalam presentasi ini adalah: solusi untuk mendukung individual yang memiliki

Harnessing Molecular Components to Build a Synthetic Regulatory Circuit: A Platform for a Smart
Metabolic Reprogramming
In electronics, arrangements of silicon components work as logic gate circuits to process the signals and allow
them to function. The same concepts have long been used in organisms since the beginning of life. Organisms
maintain metabolisms through a chain of complex biochemical reactions processed by molecular components
such as genes and protein networks. Therefore, a clear understanding of how organisms respond toendogenous and exogenous signals at the molecular level is needed to shed our ways to finetune them to ourneeds. In this talk, I would like to share my experience looking for clues to identify and develop the molecularcomponents to act differently for biotechnology purposes. I will discuss my previous research in elucidating theregulation mechanism of the key-regulatory enzyme of a metabolic pathway in the plant. Then how to
exemplify the knowledge to aid a gene finding that produces rare compounds from a medicinal plant. And
strategies to produce a high-value compound in a heterologous host. I will also discuss my recent research on
developing a novel synthetic regulatory circuit in plants, which acts as an additional molecular tool for plantscience in the era of synthetic biology. By carefully designing the synthetic regulatory circuit, we canreprogram biological functions, which brings us closer to achieving sustainability by design.

Study of the Effect of Residue Content in Catfish on Stunting Cases in Pasuruan, East Java
Catfish is a fishery resource that has a high nutritional content and is economical. In general, 100 g of catfish
contains 18 g of protein, 2.9 g of fat, 105 kCal of calories, 50 mg of sodium, 121% of the daily requirement ofvitamin B12, 26% of the daily requirement of selenium, 24% of the daily requirement of phosphorus and15% of
the daily requirement of thiamine. The fish content's function will change when it contains fish drug residues,chemicals, contaminants, or their metabolites. The presence of these residues when consumed by toddlers 0-4
years can lead to malnutrition, one of which causes stunting. Stunting cases in Pasuruan reached 12,719 out of
70,267 children. The aim of this study was to examine the effect of residues in catfish on stunting cases inPasuruan. The research method used is descriptive qualitative. The data were taken from monitoring data for
quality assurance of aquaculture safety obtained from the East Java Province Fisheries Service and population
data aged 0-4 years from the East Java Provincial Health Office, then questionnaires and interviews werecarried out with purposive sampling. The population is taken from parents with toddlers aged 0-4 years wholive in coastal areas, ponds, and other fresh waters. Based on the results of monitoring research on the safety
quality assurance of catfish aquaculture in Pasuruan, it showed that catfish contained positive residues, one ofwhich was oxytetracycline. These residues can come from the use of inaccurate doses of fish medicine,
contaminants, and existing metabolites. The existence of residual content in catfish needs to be considered bymothers who have toddlers aged 0-4 years and the Regional Health Service so that consumption of catfish is
free from residue content. This is because the residual content in fish can cause neurological disorders in
toddlers.

Natural History Research on Biodiversity Using Molecular Biology and Multiomics Approaches
The natural history as a scientific field to catalogue and understand biodiversity dates back to the dawn ofhuman civilization. Such a long history has helped humans to accumulate a vast amount of samples and data of
biodiversity. Recent rapid developments in molecular biology, biotechnology, and genomics have provided
various tools that can be employed in biodiversity research. This development thus offers t the potential for
utilizing an enormous amount of natural history samples and data, making a comprehensive study on
biodiversity feasible. Only when we have a systematic, comprehensive, and correct understanding of thenatural history aspect of biodiversity, we will be able to use the obtained insights and information for direct
applications beneficial to humans. Here, I will explore the interconnection between biodiversity research andnatural history studies. I will also delve into how molecular and multiomics methods can address several
limitations and challenges in biodiversity research. Additionally, I will emphasize the significance of
conventional natural history research methods in advancing our knowledge of biodiversity. While discussing
the integration of novel biomolecular methods into biodiversity studies and natural history research, I willaddress some of the challenges faced when implementing these "trendy" approaches. Moreover, I will propose
potential solutions to overcome these hindrances. To illustrate these concepts, I will present ongoing research
projects in my lab that have received extramural fundings. Furthermore, I will offer insights into the future
directions of the field, focusing on the prospects and necessities of initiating such research in, and for,Indonesia.

Animal, Plant and soil microbiomes: An unexplored source for tackling global warming
Food security and environmental safety are the major problems of today's world and several countries arebadly affected by the effects of global warming. It is a dire need to make projects which can target both the
problems at once. There is an interesting cross talks among the animal and plant microbiomes and theirbalance affect the overall carbon footprints. It has been shown that certain microbiota can help reduce
methane emissions from ruminants such as dairy cows. Similarly there are means to mitigate methane
emissions in paddy fields by appropriate soil microbiomes. The multipronged approach to identify microbiomesof animals and application of omics technology, animals, plants and soil integrative microbiome analysis canbring out interesting candidates that can be used in feed or fertilizers to address global warming and foodsecurity issues, while maintaining healthier environment. We can develop two organic products; microbiota
directed feed and microbiota directed fertilizer. The objective of the study is to reveal diversity, abundance
and functional relevance of the microbiomes and their application towards cleaner production andenvironment. Furthermore, a more clear image of microbiome directed feed, fertilizer and host axis will be

Utilization of Kaffir Lime Extract as A Natural Coagulant and its Effect on The Characteristics of IRR 118
Clone Rubber
Natural rubber is a plantation commodity that has a significant role in the country's economy. This study aims
to determine the effect of the natural coagulant extract of kaffir lime with centrifugation and noncentrifugation treatment on the coagulation process, pH and coagulation time, characteristics of rubber clone
IRR 118 and comparison of the quality of rubber with 2% formic acid chemical coagulant. The volume ofcoagulant used was 75 mL mixed with 150 mL of latex, so that coagulation occurred and produced coagulum.
Then the resulting coagulum is analyzed for the characteristics of the rubber to determine the quality of therubber. Characteristic analysis carried out was Dry Rubber Content (DRC), Initial Plasticity (Po), Plasticity
Retention Index (PRI), Mooney Viscosity, ash content, impurities content, volatile matter content, and nitrogencontent. The results showed that the natural coagulant extract of kaffir lime could coagulate latex, lowering
the pH of latex thereby speeding up coagulation time. From the rubber characteristic test using kaffir lime
natural coagulant it complies with SNI 06-1903-2017 SIR 20. The quality of rubber produced from using kaffir
lime natural coagulant extract as a coagulant can equate the quality of rubber produced by using 2% formic
acid chemical coagulant, but coagulant The natural ingredients used have drawbacks, namely the availability ofseasonal fruit, and the need for treatment before being used as a coagulant.

Molecular Approach for Identification of Spodoptera frugiperda Strain in Indonesia using COI(Cytochrome c oxidase Subunit I), and Tpi (Triosephosphate Isomerase)
Fall armyworm, Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae), can cause severe damage to maize,
rice, and 80 other plant species. This pest attacks all stages of plant growth, causing production failure. Early
symptoms of this pest attack are the presence of larvae and coarse powder resembling sawdust on the uppersurface of the leaves or around the shoots of plants. Spodoptera frugiperda is an invasive pest that is well
adapted and capable of long flight. This study aims to determine the strains of S. frugiperda from several
regions in Indonesia with a molecular approach, namely by analysis of the COI (Cytochrome c Oxidase Subunit I)
and Tpi (Triosephosphate isomerase) genes. Insect samples used in this study were taken from several regionsin Indonesia such as the City of Padang, Jambi, Bogor, Pinrang, Purwokerto, Tegal, Pontianak, and Morotai
Regency. Homology analysis of COIA, COIB and Tpi genes was carried out using the BLAST application in the
NCBI (National Center for Biotechnology Information) program, while phylogenetic analysis was carried out
using the Mega X. Spodoptera frugiperda application from several cities of Jambi, Bogor, Pinrang, Purwokerto,
Tegal, Pontianak, and Morotai Regency is an R strain and from Padang City is a C strain according to the COIA
gene analysis. The results of the phylogenetic analysis showed that S. frugiperda from Jambi, Bogor, Pinrang,
Purwokerto, Tegal, Pontianak, and Morotai Regencies were closely related to S. frugiperda from China, Nepal,
Florida and France. Based on the results of the COIB gene analysis from all locations, the results of the R-strain
were obtained. The results of the Tpi gene analysis from several locations obtained the C-strain. Strain

What and How of Geoparks: Mass Media Perspectives in Indonesia
A geopark is a region with significant and intriguing geological history. Due to its exceptional geological,
biological, and cultural potential, Indonesia deserves and needs this designation. Currently, ten geoparks inIndonesia have received global recognition as UNESCO Global Geoparks. However, the efforts andaccomplishment of becoming a world heritage site may be in vain if it is not known, supported, and of interest
to the entire Indonesian population. In this situation, the media play a crucial role. It is necessary, therefore, toinvestigate the media's perspective on the formation and acquisition of UNESCO Global Geopark status. The
research was conducted using both quantitative and qualitative methods. Using quantitative text analysis,
framing analysis, and supplemented by in-depth interviews, data was extracted from national conventional
mass media coverage and processed. The anticipated outcome is a recommendation for geopark
administrators and activists to identify opportunities and challenges in socializing geoparks with the goal ofpreserving natural resources and promoting sustainable well-being.

INDONESIA NICKEL MANAGEMENT ON STATE DEFENSE AND ENERGY SECURITY
Nickel is an important component of battery materials that supports the use of Internal Combustion Engine
vehicles to electric vehicles. Indonesia has the largest nickel reserves in the world, especially in southeast
Sulawesi and central Sulawesi. The research issues are that the management of nickel resources has not beenmaximized and has not been controlled by Indonesia and its role in national defense and energy security. There
are three largest nickel management companies that are dominated by China, namely PT. Virtue Dragon Nickel
Industry (VDNI), PT. Obsidian Stainless Steel (OSS) and PT. Indonesia Morowali Industrial Park (IMIP). The
objective of this study is to analyze nickel management in terms of national defense, threats, and the role ofnickel in strengthening energy security and national defense. This study used qualitative methods. Dataobtained from the participants were analyzed using a qualitative analysis technique. The results show thatnickel management was not able to achieve national interests, contrary to Article 33 of the 1945 Constitution.
China conducts monopsony and extended quasi-territory on nickel processing with sharp power, and its
management provides negative externalities to the environment that endanger the people, so that it canthreaten national defense. These threats include national threats in the form of potential originating from One
Belt One Road (OBOR) and state actors. Nickel can be used as a defense system, electric vehicle batteries forcertain military operations and anti-radar paint, and nickel can support the availability and acceptability aspects
to support Indonesia's energy security. The Conclusions of nickel management are related to China's actions incontrolling Indonesian nickel, which have an impact on national defense and Indonesia's energy security.

Profile of ASEAN research collaborations with special focus on Indonesia; Scopus analyses 2000 – 2022
Collaboration among ASEAN research communities is crucial for fostering innovation, knowledge exchange,
and addressing regional challenges. However, despite the potential benefits, the extent of collaboration within
ASEAN remains an underexplored area. This study aims to shed light on the current state of collaboration
among ASEAN research communities by analyzing Scopus data from 2000 to 2022. Across 23 years, ASEAN
produced over 1.5 million scopus-indexed publications. Top 5 ASEAN producers of scientific papers are
Malaysia (453K), Singapore (389K), Indonesia (313K), Thailand (272K), and Viet Nam (119K). The top 3 areas ofresearch include engineering, computer science, and medicine. Governments of Malaysia, Thailand, andSingapore are the main funders. Despite, these voluminous scholarly publications, the papers were barely
produced from collaborations between ASEAN countries. Except between Malaysia and Indonesia, no other
ASEAN countries showed any other ASEAN counterpart as their top 5 collaborators. With 17K joint papers(mostly on Engineering), Malaysia is Indonesia’s top collaborator, while Indonesia ranked 5 as Malaysia’s
collaborator. Malaysian institutions are the dominant funders in collaborations between Indonesian and
Malaysian institutions. Across the span of 23 years, Indonesia’s collaboration produced 4.2K papers withThailand, 2.6K papers with Singapore, and 1.9K papers papers with each Viet Nam and Philippines. With thelatter countries, Japan, US, and European funders dominated the publications. In conclusion, there is a lack of
substantial collaboration between ASEAN countries in terms of research output. The limited intra-ASEAN
collaboration highlights the need for increased efforts to foster collaboration and knowledge exchange within
the region. Governments, research institutions, and funding agencies should consider promoting andsupporting initiatives that encourage cross-border collaborations, especially between countries like Indonesia
and its ASEAN counterparts. Strengthening ASEAN research collaborations has the potential to drive
innovation, address regional challenges, and advance scientific progress in the ASEAN community.

Women's Economic Engagement and Decision-Making in the Conversion to Cleaner Energy
In Indonesia, cleaner energy conversion was implemented in 2007 and has since reduced energy-related
spending and enhanced household members' engagement in economic activities. This study examines theeffects of renewable energy conversion on women's employment rates and involvement in household
decision-making. Data are examined using a difference-in-difference (DiD) method from wave 3 (2000) to wave
4 (2014) of the Indonesian Family Life Survey (IFLS). Our findings indicate that the usage of renewable energy
has a considerable influence on urban females who are not household heads and boosts economic involvement
among women as measured by their working hours. It elevates females' status in the family's decision-making
process regarding the child's education, having a substantial influence in metropolitan settings. We also
discover that education plays a significant role, with favourable effects on working hours and the shifting
effects of positions of decision-making when included as a covariate.

English for Business to Improve Sales in Indonesian SME and Going Global in 5.0 Era
SME is our nation’s pivoting fulcrum in economy growth. To fully maximize the growth of Indonesian economy,
SMEs need to export their products. Oftentimes, the online marketplace used in exporting their products arepresented in the English language, like Amazon, Alibaba, etc. Selling products using foreign or international
platform like Amazon or Alibaba is more profitable than selling on local or localized platforms like the ones
existed in Indonesia. This is a big time chance for Indonesian business leaders, and why knowledge about thisshould be on top of priorities for them. One of the skills needed to be able to operate today’s modern
technologies is English skill. Without English ability, it will be hard to interpret the commands on the platforms
and communicate with customers and make selling.
The aim of this study is to analyze the difficulties by Indonesian business leaders in exporting their products
internationally and the strategies to overcome it. This study employs qualitative method with case study
analysis from one small and one medium company. For the data, a questionnaire and an interview isadministered. The problems found by Indonesian business leaders are oftentimes the difficulty andobliviousness to access proper English lessons and the unsupportive environment for establishing English
skills. The skills found to be difficult for SMEs’ employees are including speaking, reading, writing, and listening
respectively. Therefore, we need to figure out solutions such as for the government to conduct workshops,
generating a free website to learn business English, and granting subsidies for free online English courses forthe enterprises’ employees. Business leaders and employees can also utilize free online platform such as
Duolingo. Then, Indonesian SMEs can be world-leading exporters in the international stage.

Exploring Gender Disparities in Facebook Usage Among Teachers: Striving to Close Gender Disparities in
Teacher Professional Development
Facebook users' profiles and engagement have been shown to differ by gender. While social media can provide
equitable and accessible spaces for professional learning for all genders, this area has garnered limited
attention. This study examined gender differences of 440 Indonesian mathematics teachers, in relation to
Facebook socio-demographic variables (i.e., for how long the users have been on Facebook, device types andlocations of accessing Facebook, and the size of Facebook networks), with the intention of exploring whether
Facebook Groups (FGs) can be utilized as a professional development tool. Statistical analyses revealed nodifferences between male and female teachers in terms of how long they have been using Facebook. However,access to Facebook varied widely by place (females at home c/f. males at work). There were also significant
gender differences in the method of accessing Facebook (females via mobile phones and tablets c/f. males via
laptops and desktops). In terms of the number of friends the participants had on Facebook, there were no
significant gender differences. However, the number of FGs that they belonged to differed slightly. Most
females belong to ten or fewer FGs, with a larger percentage of females belonging to less than six FGs. This
study further revealed no gender differences in the type of educational FGs most valued by participants, theirreasons for selecting most valued FGs, and the disliked aspects of engaging with the group. Overall, the study
shows that FGs offer a way for equal and accessible professional development for both men and women.

Smart Technologies May Boost Growth, but Understanding People’s Challenges Is Key
Indonesia is blessed with youthful demographic and abundance of natural resources. But the world's
overwhelming speed of automatization through smart technologies may undermine those advantages. The
good news is, Indonesian people are also known for their creativity and diversity, strengths that produce things
not easily replaceable by machines. Studies have also shown that placing people at the center is the only way
to ensure the sustainability of a smart technology adoption. Therefore, Indonesia has the potential of reaping
optimum benefits by combining the 'bonuses' with a wise smart technology adoption. This talk presents
exploratory case studies that demonstrate a people-centered process of seeking the potential of smart andsustainable technologies adoption. Namely; A study on designing renewable energy systems for off-gridcommunities, and an electric vehicle technology readiness assessment in Indonesia. Additionally, a case study
from Japan on autonomous vehicle adoption potential is also discussed as a comparison. Key findings from therespective studies are: 1) The need for a local-economy integrated renewable energy system and exemption
from restrictive pricing regulation, 2) A closer communication and collaboration between electric vehicle
technology readiness stakeholders, and 3) An autonomous car-sharing business model for reduced carbon
footprint and financial commitments of potential users. Ensuring smart technology adoption is motivated by
the goal of solving existing social issues rather than being technology-driven, will lead to better sustainability
and minimize investment risks. Finally, this talk invites collaboration in solving Indonesia's waste management
challenges with smart waste management technologies.

Student Perceptions of The Effectiveness of Using Computer Simulation and Animation in Chemistry
Learning in Senior High Schools in Indonesia
The development of information and communication technology (ICT) has dramatically changed the roles ofteachers and students in the classroom. This, for example, translates into the current use of computer
simulations and animation in chemistry lessons. However, there has been no exploration of student cognitionon the use of information and communication technology in learning subjects. Therefore, this study examines
students' cognition of the use of computer simulations and animations in chemistry learning. This study used amixed methodological approach to collect quantitative and qualitative data from 156 participants throughquestionnaires and group discussions. Quantitative data were analyzed in detail using frequency andpercentage, while qualitative data was analyzed thematically. The findings show that most (70%) students findcomputer simulation and animation (CSA) easy to use. Furthermore, an average of 76% of students have apositive understanding of the benefits of CSA in learning chemistry concepts. In addition, 72% have a very
positive attitude towards the use of CSA and 78% of students have a very positive understanding of the
behaviol intention of using CSA in teaching and learning chemistry concepts. However, 87% of students have astrong understanding that having adequate information and communication technology resources in school
and access to computer laboratories can influence them to learn chemistry concepts with computers as
educational tools. Therefore, the current study suggests that the use of computer simulation and animation
should be emphasized in the teaching and learning of chemistry concepts in high school

Rural Development
Nutmeg (Myristica fragrans Houtt.) industry in Indonesia has developed extensively from production ofnutmeg fruits to processing of various nutmeg products. Currently Indonesia supplies more than 50% of theworld’s total demand for nutmeg spices and nutmeg oil. Development of nutmeg industry also plays animportant role as income sources for the local community and has brought impact in enhancing the rural
economy. However, development nutmeg industry in Indonesia has still faced several severe problems,
especially in providing sustainable and high-quality products for international market. This research aims toanalyze the actual condition of nutmeg cultivation, processing, distribution and sales in nutmeg producing
areas in Indonesia from technological, management and industrial development perspectives and to examine
the benefits and limitations of three different development patterns of the nutmeg industry in Indonesia, suchas government-support pattern, cooperative-support pattern, and individual pattern, in order to determine
potential development pattern for nutmeg industry in the future. This research has been conducted throughfield survey and case studies in four important nutmeg producing areas in Indonesia, namely Fakfak Regency,
West Papua Province; South Aceh Regency, Aceh Province; Bogor Regency, West Java Province; and Ternate
and Tidore Regency, North Maluku Province.

LinguaForense: Prototipe Aplikasi Berbasis Python untuk Analisis Linguistik Forensik
Dalam dunia modern yang terus berkembang, penting untuk mengembangkan metode analisis yang efektifdalam bidang forensik, terutama dalam analisis linguistik forensik. Dalam tulisan ini, kami ingin
memperkenalkan “LinguaForense”, sebuah prototipe aplikasi berbasis Python yang kami rancang khusus untuk
analisis linguistik forensik. Prototipe aplikasi ini didasarkan pada metode pengolahan bahasa alami (natural
language processing) dan menggunakan beberapa teknik seperti pemrosesan teks, klasifikasi, danpenambangan informasi. Aplikasi ini menerima masukan teks berupa dokumen atau percakapan dalam bentuk
teks, dan kemudian menganalisis struktur dan konten bahasa dalam teks tersebut. Beberapa fitur utama yangdisediakan oleh prototipe aplikasi ini antara lain analisis sentimen, klasifikasi teks, dan identifikasi penulis.
Analisis sentimen digunakan untuk menentukan emosi atau pendapat yang terkandung dalam teks, sedangkan
klasifikasi teks digunakan untuk mengidentifikasi jenis teks tertentu, misalnya apakah teks tersebut merupakan
pesan ancaman atau spam. Identifikasi penulis memanfaatkan analisis stilistika untuk membandingkan ciri-cirilinguistik dalam teks dengan profil penulis yang sudah ada. Selain itu, prototipe aplikasi ini juga menyediakan
alat visualisasi yang membantu pengguna dalam memahami hasil analisis secara lebih intuitif, seperti grafik dan
diagram. Pengguna juga dapat melakukan penyesuaian dan pengaturan tambahan sesuai dengan kebutuhan
mereka. Melalui pengembangan prototipe aplikasi ini, diharapkan dapat membantu ahli forensik linguistik
dalam menganalisis teks dengan lebih efisien dan akurat. Aplikasi ini memiliki potensi untuk digunakan dalamberbagai kasus forensik yang melibatkan analisis linguistik, seperti investigasi kejahatan cyber, penyelidikan
pidana, dan analisis pesan terenkripsi.

Hate Speech Intolerant Analysis Detection: A Proposed Method
Hate speech generally refers to expressions that incite harm (particularly discrimination, hostility, or violence)
against a specific target based on the target's identification with a particular social or demographic group.
Hate speech can also include expressions that encourage a climate of prejudice and intolerance, assuming thatsuch a climate can lead to discrimination, hostility, and targeted violence. Intolerant Analysis is also a proposedsolution for detecting social media accounts that have the potential to continue to spread hate news. In theperspective of the field of psychology, early detection is done by studying the behavior patterns andcharacteristics that are raised by social media account users based on the history of previous posts. Thismethod is known as a predictor of new phenomena that will appear so that there is an initial step in preventing
a predicted bad condition/thing from happening. In the case of hate speech, predictor techniques are used forthe early detection of accounts that have the potential to continue to spread hateful information. This
research proposed a method to classify intolerant and tolerant twitter comments, not just the sentiment. The
performance of sentiment algorithm is 87% of accuracy and the performance of intolerant algorithm is 96% of
accuracy. Although the accuracy is high, the algorithm still needs more validation from expertise inpsychologist.

Chopping Machines Prototype as an Organic Waste Processor
Waste utilization is used in various sectors such as industry, food, manufacturing, etc. Food or vegetable waste
is one type of organic waste. Organic waste can be used as organic fertilizer and animal feed. This study aims to
make a prototype of an organic waste chopping machine. Furthermore, the chopped results can be used as raw
material for compost or animal feed. The main driving components in the prototype organic waste chopper are
electric motors with a power of 1/2 HP and 2880 rpm, reducers with a rotation ratio of 1/20, a pulley ratio of
3/4, and a belt type A-66. Analysis of the prototype design of the organic waste chopper machine, namely thecalculation of the planning of the v-belt, pulley, and the calculation of the rate and torque on the blade shaft.
The capacity of the chopping results is distinguished based on 2 types of tests, namely testing using a reducer
and without a reducer. The types of waste that were chopped were vegetable waste, organic skin waste, andcassava. Testing with a reducer produces shredded waste with a capacity of 16.5 kg/hour. Also, 8.7 kg/hour fororganic skin waste, and 26.13 kg/hour for cassava. Meanwhile, the test results without using a reducer resulted
in chopped vegetable waste as much as 111.84 kg/hour, and 93.72 kg/hour for organic skin waste.

Amine-Modified Zeolite as a Solid Sorbent for CO2 Capture
Carbon capture is a process of capturing CO2 gas from the atmosphere or industry that generates CO2. One of
the industries that release CO2 is coal power plants, which increase CO2 emissions rapidly due to higher energy
demand. Carbon capture using solid sorbent is one of the promising technologies due to its several
advantages, such as high adsorption capacity, lower cost of regeneration, and fast kinetics. The mechanism of
CO2 adsorption on adsorbent is mostly physisorption, which makes adsorbent more effective at ambient
temperature. Amine modification on adsorbent is conducted to increase CO2 adsorption capacity andtemperature stability when used at higher temperatures. This experimental work uses amine-modified zeolite
13X as a solid sorbent for CO2 capture application. The solid sorbent’s characterisation has been done using
SEM analysis, FTIR, TGA, BET surface area, and micro-DSC analysis. The CO2 adsorption study is conductedusing a laboratory scale of a packed bed reactor. The adsorption capacity and regeneration cycles of aminemodified zeolite are compared with pristine zeolite. From the experiments, amine-modified zeolite performs
better adsorption than neat zeolite. This research aims to develop adsorbent material that can give higher CO2
adsorption capacity which can be applied to capture CO2 from the flue gas of coal power plants, cement or
steel industries, etc.

Antimicrobial resistance of nasal Staphylococcus species in lactating mothers and their infantsCommon bacteria in the nasal cavity can act as opportunistic pathogens that cause infections under certain
conditions. Screening for commensal bacteria in the nasal cavity in nursing mothers can determine antibiotic
resistance which can be used as a reference for therapy and prevention of infection in their babies. This study
aims to obtain a pattern of sensitivity of Staphylococcus species in the noses of mothers and their babies. A
total of 47 pairs of mothers and babies were enrolled using a cross-sectional study design. Nasal swabs werecollected and cultured on mannitol salt (MSA) agar. Identification of species and antibiotic resistance using
Vitek-2. Overall we found that the most Staphylococcus species was S.aureus. Other species obtained were
Coagulase-negative staphylococci (CoNS), namely S.epidermidis and S.haemolyticus S.hominis ssp hominins,
S.ludgunensis, S.warneri, S.lentus, S.capitis, S.gallinarum, S.auricularis, and S. saprophyticus. We found 29/47(62%) S. aureus, 23% MRSA. We also found 29/47 (69%) were methicillin-resistant Coagulase-negative
staphylococci (MRCoNS). We found more than 50% of isolates resistant to benzylpenicillin, clindamycin,
erythromycin, and oxacillin. The prevalence of MRCoNS nasal carriers is high in lactating mothers and infants on
a community basis. Monitoring and control of methicillin-resistant strains is necessary.

Development of Engineered Modular Endolysin as Antimicrobial Candidate
Infection of microbial pathogens, such as Streptococcus and Staphylococcus, can cause diverse animal andhuman diseases and further systemic infections. The increasing antibiotic resistance of microbial pathogens is amajor threat to public health. Bacteriophage modular endolysins and their engineered ones are promisingalternative antimicrobial candidates unlikely to evoke antimicrobial resistance. Given the previous success andthe potential of its modular design, our study has developed the engineered modular endolysin as a ‘tailormade’ antimicrobial candidate specifically targeting Streptococcal and Staphylococcal infections. The researchhas designed in silico the synthetic gene encoding the engineered modular endolysin and has conductedpreliminary study in expression, purification, molecular characterization of the recombinant protein, andbioinformatics analysis on molecular modelling and molecular docking simulations. In the on going and future
research, further molecular docking and molecular dynamics simulations as well as Cryo-EM analysis will be
conducted to study the predicted binding activity and enzymatic lysis activity as well as structure andfunctionality of the engineered modular endolysin, respectively. Based on the data of the molecularexperiment and bioinformatics analysis, further production of the engineered modular endolysin and its invitro activity assay will be conducted. In addition, the development of whole genome sequencing (WGS)
analysis of bacteriophages from microbial pathogens in Indonesia as well as further development of potential
therapy based on bacteriophages and modular endolysins and their engineered ones in order to control
microbial pathogen infections in Indonesia will be carry out.

Synthesizing 2h/e2 Resistance Plateau at the First Landau Level Confined in A Quantum Point Contact
A comprehensive understanding of quantum Hall edge transmission, especially the hole-conjugate of a
Laughlin state such as a 2/3 state, is critical for advancing fundamental quantum Hall physics and enhancing thedesign of quantum Hall edge interferometry. In this study, we report a robust intermediate 2h/e2 resistancequantization in a quantum point contact (QPC) when the bulk is set at the fractional filling 2/3 quantum Hall
state. Our results suggest the occurrence of two equilibration processes. First, the co-propagating 1/3 edges
moving along a soft QPC arm confining potential fully equilibrate and act as a single 2/3 edge mode. Second,the 2/3 edge mode is further equilibrated with an integer 1 edge mode formed in the QPC. The complete
mixing between them results in a diagonal resistance value quantized at 2h/e2. Similar processes occur for abulk filling 5/3, leading to an intermediate (2/3)h/e2 resistance quantization.

Negatively Charged Tight SPSf/PEG400/Halloysite Nanotube Ultrafiltration Membrane for High Removal
Efficiency of Dyes
Ultrafiltration (UF) membranes are widely used in wastewater treatment due to their high productivity and low
energy requirements. However, their limited rejection of soluble contaminants, like dyes, hampers theirapplication as single-stage membranes. In this study, a tight UF membrane was prepared by blending
sulfonated polysulfone (SPSf) with polyethylene glycol (PEG400) and halloysite nanotubes (HNT) as additives.
The effect of sulfonation time on the UF membrane's morphology, hydrophilicity, porosity, permeate flux, anddye rejection was investigated. The resulting UF membrane exhibited an average porosity of 78% and ahydrophilic nature, as indicated by a water contact angle between 72-80°. The addition of sulfonic acid groups(-SO3-) to the PSf chain enhanced hydrophilicity and introduced a negative charge. The SPSf/PEG400/HNT UF
membrane exhibited the highest rejection rates for Blue 2BLN (95.5%), Naphthol AS (90.4%), and TDS (9.4%).
The pure water flux (PWF) was 100 L.m-2.h-1. The research findings demonstrate that the SPSf/PEG400/HNT
tight-UF membrane can serve as a cost-effective and efficient alternative for wastewater treatment,
specifically in the case of textile wastewater. The membrane effectively produces clean water that can bereused in various textile industry processes.

The D-enantiomer of LL-37 Shows Comparable Antiviral Activity Against Zika Virus As the Native Formof LL-37
Zika virus (ZIKV) is a mosquito-borne flavivirus that is predominantly transmitted by Aedes mosquitoes. ZIKV
can also be transmitted vertically from mother to fetus and by sexual transmission. There is currently noeffective treatment for ZIKV infections, and given the spread of this disease worldwide, there is an urgent
need for new, low-cost and efficacious treatments. LL-37, the sole human cathelicidin which are part of the
innate immune system, has been shown to have antiviral activity against a wide range of enveloped viralpathogens. However, a major translational limitation of LL-37 is its susceptibility to post-translational
modifications (PTMs) including proteolysis. In the present study, we investigated the in-vitro effect of thenative form, D-form and scrambled LL-37 on ZIKV infection in A549 cells. The intracellular viral protein wasquantified using the In-Cell Western assay. The culture supernatant was assessed for infectious viral particles
by plaque forming unit assay and the level of cytokine release was determined using fluorescent microbead
immunoassay. The L- and D-form of LL-37 effectively reduce ZIKV infectivity in A549 cells as compared to virus
control. In terms of production of viral particles, the addition of D-LL-37 post infection showed infectivity
reduction with a better significance than the native LL-37. Treatment of the ZIKV with scrambled LL-37 had noeffect on ZIKV infectivity and the viral load as compared to virus control. Molecular docking studies revealedpossible binding of L-form and D-form of LL-37 to the ZIKV envelope (E) protein dimer. The D-form of LL-37
binds to ZIKV E protein with a better stability compared to the native form. Together, our in-vitro experiments
and in-silico analyses suggest that the native and D-form of LL-37 inhibit ZIKV at the stage of entry into thecells by binding to the E protein and engineering LL-37 into more biologically stable forms improve its antiviralpotential against ZIKV infections.
