Una mirada al estudio de la formación de bibliotecólogos en América Latina y el Caribe
Authors: Licea de Arenas Judith , González Nando Eric M.
Published: August 2023

Podemos afirmar que todos los países del orbe necesitan de un número suficiente de profesionales de la información para contribuir a su desarrollo, sin embargo, tal percepción es todavía una utopía en los países del subcontinente americano y si bien los programas de formación de bibliotecólogos surgen en los albores del siglo XX su aparición y consolidación ha sido lenta y desigual: hay países sin estudios en la especialidad y países donde las prácticas educativas se centran en los profesores en el aula, donde no se combina la práctica docente con el uso de información y donde se continúa la preparación de personal para el trabajo rutinario. Por tanto ¿la formación de bibliotecólogos ha estado relacionada con las áreas prioritarias de las naciones de la región: educación, alimentación, salud, ciencia, comunicaciones, tecnología, innovación y transporte? Lo anterior presupone una educación ad hoc para los requerimientos sociales, es decir, los bibliotecólogos deberán aprender a resolver problemas, a trabajar en grupo, a investigar, a comunicarse oralmente y por escrito, a mostrar compromiso social, a ser activos en su comunidad y a actuar con ética.

Published: August 2023

Abstract: Soil fertility plays a important role in figuring out agricultural productiveness and sustainability. Traditional methods of assessing soil fertility involve time-consuming and high-priced laboratory tests, restricting their scalability and real-time applicability. To overcome these challenges, this study proposes a data-driven method utilizing machine learning techniques for accurate and efficient soil fertility prediction. Several machine learning algorithms, inclusive of decision trees, Random Forests, k nearest neighbors, and Gradient Boosting Machines (GBM), are employed to model the complex relationships among soil properties and fertility. Feature selection techniques are carried out to identify the most influential soil parameters for enhanced prediction accuracy and reduced model complexity.The outcomes demonstrate that machine learning models can appropriately predict soil fertility, outperforming traditional approaches in terms of speed and cost-effectiveness. Moreover, the characteristic selection process identifies key soil properties that have the most significant effect on fertility, offering valuable insights for agricultural decision-making and targeted soil management. The proposed approach offers potential applications in precision agriculture, enabling farmers to make knowledgeable choices regarding crop selection, nutrient management, and irrigation strategies based totally on actual-time soil fertility predictions. By optimizing resource allocation and minimizing environmental influences, this data-driven solution contributes to the promotion sustainable agricultural practices and guarantees food safety for a growing global population. These are the essential nutrients that the crop requires for its growth pH nitrogen(N), phosphorus(P), potassium(K), CaCo3, Organic Carbon, Organic matter, CEC (Cation exchange capacity) .

Authors: Sutar Sandeep Gajanan
Published: August 2023

Abstract: Data outsourcing is now subject to additional safety and privacy concerns as a result of the rise in cloud computing demand. Because data management was moved to words an unstable cloud during the outsourcing stage of the data, data permit control identified a key problem in the cloud repository. This analysis uses the Attribute-Based Access Control method to control access to the cloud storage to solve the issue. The data is reserved in the cloud and protected by strict security before the user may access it. This model takes into account specific properties of the cloud data stored in the database authentication process in order to store the information of registered collections alongside the user-committed data. Each of the clusters has a unique set of benefits, including usernames, group names, and registry message authorization codes. Prior to sending the data to the service provider, it should be encrypted to ensure its security. However, there may occasionally be problems with the supplier’s security measures. In this outcome, a variety of metrics are analyzed, such as the amount of time used for encryption, decryption, key generation, and time consumption. The numerous existing techniques, like Nth Truncated Ring Units and Cipher text. Constraints on online storage access may make policy attribute-based encryption impossible. The time of encryption is reduced by 20% and 36%, respectively, via NTRU and CP-ABE. The proposed technique decrypts data 10.64% faster than the current approach, which decrypts data 19% more slowly.

Assessment of various Hamiltonian partitionings for the electronic structure problem on a quantum computer using the Trotter approximation
Authors: Martínez-Martínez Luis A. , Yen Tzu-Ching , Izmaylov Artur F.
Published: August 2023

Solving the electronic structure problem via unitary evolution of the electronic Hamiltonian is one of the promising applications of digital quantum computers. One of the practical strategies to implement the unitary evolution is via Trotterization, where a sequence of short-time evolutions of fast-forwardable (i.e. efficiently diagonalizable) Hamiltonian fragments is used. Given multiple choices of possible Hamiltonian decompositions to fast-forwardable fragments, the accuracy of the Hamiltonian evolution depends on the choice of the fragments. We assess efficiency of multiple Hamiltonian partitioning techniques using fermionic and qubit algebras for the Trotterization. Use of symmetries of the electronic Hamiltonian and its fragments significantly reduces the Trotter error. This reduction makes fermionic-based partitioning Trotter errors lower compared to those in qubit-based techniques. However, from the simulation-cost standpoint, fermionic methods tend to introduce quantum circuits with a greater number of T-gates at each Trotter step and thus are more computationally expensive compared to their qubit counterparts.

Aim: to review the modern approaches to the diagnosis and treatment ofC. difficile-associated disease in adults and present the resolution of the Expert Council held on March 25, 2023 in Moscow.

General provisions.C. difficileis the most important nosocomial pathogen which spores are also commonly found in the environment. Microbiota impairment, primarily due to the use of antibacterial drugs, is a key stage in the development ofC. difficile-associated disease. A search for an infection should be carried out only in patients with diarrhea, and it is advisable to use at least 2 laboratory methods. The drug of choice for first-line treatment is vancomycin. If drug treatment is ineffective or the patient has recurrent clostridial infection, fecal microbiota transplantation should be considered. The probiotic strainSaccharomyces boulardii CNCM I-745has a direct inhibitory effect onC. difficiletoxin A, promotes normalization of the intestinal microbiota composition, and decreases the inflammatory reaction in colonic mucosa colonized with a toxigenic strain ofC. difficile.

Conclusions. Addition of the probiotic strainSaccharomyces boulardii CNCM I-745to antibacterial therapy promotes both primary and secondary prevention ofC. difficile-associated disease.

Published: August 2023

Aim: the reason for the publication was the rare occurrence, as well as the non-specificity of symptoms of the cystic form of duodenal dystrophy. The listed features of this disease lead to difficulties in its differential diagnosis and the choice of the optimal method of treatment.

General statements. The report is devoted to the description of a case of successful treatment of a cystic form of duodenal dystrophy — a chronic inflammation of the pancreatic tissue, ectopic in the wall of the duodenum. A 47-year-old patient was admitted to the clinic with complaints of persistent abdominal pain, periodic vomiting, general weakness, weight loss of 20 kg in three months. With the help of computed tomography, the diagnosis was established, the tumor process was rejected, and chronic pancreatitis was detected in the orthotopic pancreas. Due to the presence of changes in the main pancreas, the patient underwent pancreatoduodenal resection. The features of the operation were pronounced infiltrative changes and pronounced vitreous tissue edema, which made it difficult to mobilize the hepatic flexure of the colon and duodenum.

Conclusion. Pancreatoduodenal resection is the optimal surgical intervention for the combination of cystic form of duodenal dystrophy with sub-/decompensated duodenal stenosis.

Implementasi Active Queue Management pada Jaringan Bottleneck
Authors: Fajri Misbahul , Ratnasari Anita , Prabowo Yani
Published: August 2023

Teknologi TCP end-to-end congestion control hanya menangani kemacetan jaringan dari suatu host tetapi tidak pada jaringan atau intermediate network, oleh karena itu teknologi Active Queue Management (AQM) dikembangkan untuk mengantisipasi kemacetan didalam jaringan yaitu pada router. AQM dapat mengatasi buffer overflow pada router dan mencegah terjadinya masalah sinkronisasi pada jaringan yang padat, yaitu dengan mendeteksi sebelum terjadi kemacetan jaringan. AQM RED (random early detection) dikembangkan dengan pendekatan heuristik untuk mengantikan kekurangan mekanisme Droptail pada buffer router, sehingga dapat mengatisipasi memburuknya kondisi jaringan yaitu; hilangnya paket yang berlebihan, utilitasasi link yang rendah (low throughput), dan tingginya antrian (delay), dengan demikian kemacetan yang parah (congestion collapse) tidak akan terjadi. Permasalahan ini menarik untuk dipelajari dampak implementasi AQM yang akan dilakukan dalam penelitian ini. Protokol AQM adalah mekanisme pengendali kemacetan yang diterapkan pada lapisan ke-tiga OSI pada peralatan jaringan router, dengan menggunakan simulator NS2 dibuat topologi jaringan bottleneck dan diuji coba dengan skenario trafik. Pada penelitian ini akan diimplementasikan metode AQM RED yang disimulasikan dengan pengiriman paket FTP dengan beberapa skenario trafik. Hasilnya berupa karakteristik jaringan dapat dilihat yaitu; jumlah paket yang ada pada buffer router, lamanya antrian paket pada buffer , dan banyakanya paket yang dibuang,  sehingga dapat dianalisa kinerja RED yang merupakan tujuan penelitian ini. Kesimpulan yang didapat menunjukan bahwa RED mempunyai keunggulan dari karakteristik delay yang rendah dibandingkan mekanisme tanpa AQM atau Drop-tail.
China-Malaysia Relations as a Campaign Strategy: The BN Prime Ministers’ Understanding of China and the Ethnic Chinese
Authors: Soon Thean Bee
Published: August 2023

During the administration of the Barisan Nasional in Malaysia, three Prime Ministers, namely Abdul Razak, Mahathir Mohamad and Najib Razak, strategically incorporated the China factor to attract the support of the Chinese voters in their respective election campaigns. These campaigns took place in 1974, 1999, and 2013. It appeared that the Prime Ministers perceived a preference among the Chinese community for China, despite the Chinese were born in Malaysia or had been granted Malaysian citizenship. Thus, Razak, Mahathir and Najib’s understanding of China and Chinese voters played a crucial role in shaping their decision to employ diplomatic relations as a campaign strategy.

Besides, this study uses Maslow’s Hierarchy of Needs to analyze the changes in the author's mindset as a traditional musician and to explore the challenges and self-identity of being a minority in the larger community.
Furthermore, this study also discusses how the author consciously and unconsciously blends her cultural heritage with Western musical influences, which later helps her to develop her own musical language and voice.
A systematic review of global guidelines for the diagnosis of penicillin allergy
Authors: Guo Yuanchao , He Ting , Lin Yunzhu
Published: August 2023

Objective: This study aimed to evaluate the global guidelines
on diagnostic methods for penicillin allergy and to provide evidence for
regulating diagnostic procedures for penicillin allergy.
Methods: PubMed, Embase, Cochrane Library, China National
Knowledge Infrastructure, Wanfang database, VIP database, Clinical
Guidelines database, World Bank GDP ranking of the top 15 countries of
the health sector, multinational organisations and related societies
websites were searched. The AGREE II instrument was used to evaluate the
methodology and reporting quality of the guidelines. Results:
34 articles were included, from 14 countries and regions, including ten
government and intergovernmental organisation guidance documents, nine
clinical guidelines, and 15 expert consensuses. After AGREE Ⅱ
evaluation, the overall quality of the included literature was not high,
and most of the literature did not show a systematic, rigorous
production process. There are apparent differences in the
recommendations of each literature, including the diagnosis object,
time, method and approach. Conclusion: The methods of allergy
diagnosis for penicillin allergy differ significantly from country to
country around the world, mainly in terms of diagnostic target,
diagnostic staff, timing, diagnostic steps, diagnostic reagents and
determination of results, with the main gaps being in the diagnostic
steps and diagnostic reagents, and further original studies are expected
to compare the advantages and disadvantages of each protocol.
Tackling critical cases of the difference operator stability occurring in applications described by 1 D distributed parameters.
Authors: Rasvan Vladimir
Published: August 2023

The paper starts from the challenge of the critical cases in difference
operator stability for neutral functional differential equations (NFDE).
Such cases occur in the NFDE associated to 1 D hyperbolic partial
differential equations (PDE) dynamics in Mechanical and Hydraulic
Engineering. For some of such applications it resulted that the
aforementioned critical (non-asymptotic) stability is connected to the
character and level of the energy losses. It is shown that suitable
choice of the losses to be taken into account can remove the critical
stability properties and give the difference operator the asymptotic
stability thus ensuring asymptotic stability for the system’s dynamics
and also other asymptotic properties.

Published: August 2023

Solar energy is a clean and sustainable source of power. Although there
are various uses for solar energy, the Solar Air Heater (SAH) has a poor
thermal efficiency. To improve thermal efficiency, a novel corrugated
jet-impinging channel has been proposed for the absorbing plate of SAHs.
A Numerical study have been performed for four different arrangements of
jets i.e., single circular, single square, 2x2 square and 3x3 square jet
array with four channels i.e., 30 , 45
, 60 and 90
corrugated over the Reynolds number range of 1969-3305 for the jet to
target plate range of 4.9-14.2. It was observed that and multiple jets
impinging increase the heat transfer significantly. An optimization
study has been performed using the parametric study. The 45
corrugated target plate with 3x3 multiple jet
impingement, 4.9 jet to target plate distance, and 3305 Reynolds number
was shown to have the best Nusselt number value. In contrast to the base
scenario, a Thermal Performance Factor of 2.3 times was achieved.
Protecting our future: Call for RSV vaccine trial in infants
Authors: riaz rumaisa , sumbal anusha , khan afsheen
Published: August 2023

Respiratory syncytial virus (RSV) is a significant infectious disease
that causes severe illness and mortality in adults and children. Despite
extensive research, an effective and safe RSV vaccine remains elusive. A
recent breakthrough in the field introduced the RSVPreF3 OA vaccine,
which proved successful in preventing RSV-related respiratory infections
and lower respiratory tract diseases in adults aged 60 years or older.
However, this vaccine has not been tested in infants, who bear a
substantial burden of RSV infections, particularly in low- and
middle-income countries (LMIC). Current preventive measures, such as
Palivizumab, have limited efficacy in reducing mortality and morbidity
in children. The approval of an RSV vaccine for adults provides an
encouraging opportunity to develop vaccines specifically tailored for
infants. This article emphasizes the urgent need for global
collaborations and increased research funding to accelerate the
development of an RSV vaccine for the pediatric population. Trials for
RSV vaccines in infants are essential to protect vulnerable infants from
RSV infections and their associated consequences.
Quadratic radiative Ag − MgO /water hybrid micropolar nanofluid flow along an exponentially contracting permeable Riga surface: Stability and entropy optimization analysis
Authors: Mandal Gopinath , Pal Dulal
Published: August 2023

The present analysis deals with the study of non-Newtonian micropolar
Silver-Magnesium Oxide ( Ag− MgO)/ H ⊭ O hybridized
nanofluid flow and heat transfer over an exponentially contracting
porous Riga surface. We have highlighted the impacts of micropolar
characteristic, quadratic thermal radiant energy in the existence of
convective conditions and velocity slip at the boundary on the
coefficient of shear stress, coefficient of couple-stress , heat
transfer factor (Nusselt number), entropy formation, velocity,
micro-rotation or angular velocity and temperature profiles under the
assumptions of nanomaterial. We have solved the highly non-linear
coupled partial differential equations numerically, using the MATLAB
programming platform with a fourth-order method to decode the boundary
value problem (bvp4c) with all relevant flow parameters. The second law
of thermodynamics is used for the calculation of the irreversibility
factor. The results point to the presence of dual-nature solutions with
a stable upper solution branch and an unstable bottom solution branch in
the contracting sheet area for a given value of the mass suction
parameter. In the presence of dual solutions, critical values have been
found, and a stability analysis is run to find more stable solutions.
Two solutions are found for the limited range of contracting parameter
λ when λ S < λ and the solutions terminate at λ ↮ λ c
in the contracting region. Additionally, the first solution generates a
positive minimum eigenvalue ( β ⊮ > ⊬ ) indicating the
stability of the solution, whereas the other solution generates a non
positive eigenvalue ( β ⊮ < ⊬ ). It was found that the shear
stress and couple stress coefficients rise with increasing suction
value, however the heat transfer factor (Nusselt number) may fall for a
stable solution. With an increase in the solid volume percentage of the
hybridized nanofluid and material component, the formation of entropy
rises noticeably. Additionally, it is noted that in both solutions, the
quadratic thermal radiating parameter, Eckert number, and Biot number
all lead to an increase in the temperature with enhancement in thickness
of the thermal barrier layer. These findings are important because
micropolar hybridized nanofluids are actively used to cool tiny
electrical devices like microchips and related equipments.

Published: August 2023

The purpose of the current study was to qualitatively explore the home
mathematical environment across two regions in two different countries
(i.e., Cuba and Mexico), replicating a qualitative study previously
conducted in Northern Ireland (NI), United Kingdom (UK; Cahoon et al.,
2017). Semi-structured interviews with parents/caregivers of children
(3-5-year-olds) in both Mexico (n = 13) and Cuba (n = 40) were completed
to investigate their views, experiences and attitudes towards the home
mathematical environment. Thematic analysis was used to explore themes
relevant to the home mathematical environment. Three consistent themes
were found in the Mexican and Cuban data: Numeracy Environment
Structure, Expectations and Attitudes and Views of Technology. Two
unique themes were found in the Mexico data: Interactions Related to
Reading or Mathematics, and Child’s Attitudes in Relation to
Mathematics. One unique theme was found in the Cuban interviews:
Interactions for Learning. Although diverse themes were identified,
consistencies were also observed. This suggests that some home numeracy
practices may be universal in nature. This research increases
understanding of human development in context.
Socialization of Emotion Regulation in Preschool Classrooms: Do Peers Matter?
Authors: Diebold Tatiana , Jaggy Ann-kathrin , Perren Sonja
Published: August 2023

The development of emotional competence is an important milestone during
early childhood. Beyond early experience within the family, the
(preschool) classroom is a relevant socialization context, and both
teachers and peers may contribute to children’s emotion-related
outcomes. Tracking changes in the emotion regulation competence of N =
173 preschool children (age in months: M = 43.3, SD = 6.6, 45% girls)
over 6 months, the current study investigated whether and how peers
contribute to differences in the development of emotion regulation in
preschool classrooms. The research questions were addressed by examining
three different kinds of peer groups: Classroom-level peer group,
friendship group, and high-status peers. Teachers rated children’s
emotion regulation competence and empathic co-regulation behavior at
three assessment points. Multilevel growth modeling provided evidence
that friendship-group empathic co-regulation (empathy, helping, and
comforting behavior) predicted changes in preschoolers’ emotion
regulation over time, confirming that friendship groups influence young
children’s emotional development.

Published: August 2023

BACKGROUND- Occasional coexistence of Juvenile Angiofibroma
(JA) and Familial Adenomatous Polyposis (FAP) has been previously noted,
and emerging understanding of molecular mechanisms in JA indicates
similarities with FAP by involvement of beta-catenin/Wnt pathway.
Congenital Hypertrophy of Retinal Pigmented Epithelium (CHRPE) is the
earliest extracolonic manifestation of FAP. METHODS- Cohort of
180 JA patients(median age-16yrs) from a hospital dataset screened for
FAP. Screening by a symptom questionnaire and evaluation for CHRPE
RESULTS- Screening identified 6/180(3.3%) as meriting further
FAP evaluations based on family history of JA in a sibling(n=2),
melaena(n=2), intestinal perforation(n=1) and CHRPE(n=1). Colonoscopy
was accepted by 3/6 patients (age 17-21 years) but did not manifest FAP.
CONCLUSIONS- Familial JA as identified in 2/180 patients
indicates further genetic mechanisms in JA. FAP screening indicates
possible FAP requiring confirmation in 3.3%. Confirmation/exclusion of
FAP in this young screen-identified group is challenging by colonoscopy
and genetic testing could be a considered alternative.
New techniques in harvesting of fasciomyocutaneus infrahyoid flap to reconstruct larger defects of advanced oral tongue cancer(T3 & T4a)
Authors: hagh Ali Bagheri , ansari reza
Published: August 2023

The aim of this study is to introduce a new modification of
fasciomyocutaneus infrahyoid flap with higher volume and longer
durability in order to reduce the need of using free flaps in
reconstructions after oral tongue cancers. six Patients with advanced
cancers of the oral tongue, especially with base of tongue involvement,
who traditionally had to be reconstructed with a free flap due to a
large defect after resection, were involved in the study. In this study,
they were reconstructed with modified fasciomyocutaneusinfrahyoid flap.
From these six patients who were reconstructed with a modified
infrahyoid flap, none of them showed evidence of necrosis or flap
complications such as flap atrophy after surgery and over the time. The
new modification of this flap can provide more volume than the previous
modifications of this flap, and lead to a more routine use of this flap
in oncological surgeries of the oral tongue.

Authors: Moilanen Johanna , Lehto-Lundén Tiina , Jägervi Lotta , Kiili Johanna , Svensson Kerstin , Svenlin Anu-Riina
Published: August 2023

The article discusses children’s citizenship by linking the dimensions of being, becoming and belonging to the concept of lived citizenship in the context of contact person and contact family interventions. Drawing on empirical research from Finland and Sweden, the article elaborates on how to identify if, and if so, how, children’s lived citizenship is constructed in contact person and contact family interventions and to what extent these constructions leave room for children’s perspectives. The results of the study indicate that contact person and contact family interventions contribute to the construction of children’s citizenship in various ways that include the perspectives on children and childhood of being, becoming and belonging. However, children’s active participation often seems to be governed by adults. Thus, giving greater attention to children’s intergenerational connections, i.e., adults’ roles in forming children’s citizenship, is needed.

Published: August 2023

In this work, an approach towards automated extraction and evaluation of static and kinematic coefficients of friction is presented. By replacing manual evaluation with an automated process, this approach yields promising results, simplifies data handling, and saves significant time. The methodology shows potential for application to a wide range of experimental data and provides advanced processing capabilities using the extracted and mathematically evaluated data points. However, for data with high signal- to-noise ratios, automatic detection still requires further optimization to improve accuracy.

The wallpaper archive—intended to house a modest historic wallpaper collection by local heritage architects Salmond Reed Architects—and the bridge are cover for a larger recovery of historical significance eclipsed by the transport infrastructure. The architecture proposed intends both memorial and future-building functions and arises out of an investigation of practice-led processes centred on casting, modelling, printing, and photography. In doing so, this creative design research demonstrates a form of architectural renovation as storytelling, in which the past is recalled not through material restoration, but re-narrativisation—a process I have come to call spectral urbanism.

Hama utama yang menyerang tanaman kopi adalah Hypothenemus hampei Ferr. Keberadaan hama ini menjadi salah satu faktor penyebab rendahnya produksi kopi. Pengendalian yang umum dilakukan adalah menggunakan insektisida sintetik yang dapat berdampak buruk bagi lingkungan. Semnetara itu, tanaman kecubung gunung (Brugmansia Suaveolens) dan mahoni (Swietenia macrophylla) mengandung metabolit sekunder yang memiliki potensi sebagai bahan insektisida nabati. Tujuan dari penelitian ini adalah untuk mengetahui kandungan fitokimia dan efektivitas insektisida nabati kombinasi daun B. suaveolens dan daun S. macrophylla dalam mengendalikan H. hampei. Penelitian dilakukan selama November 2021 sampai Januari 2022 di Laboratorium Fakultas Pertanian Universitas Yudharta Pasuruan dan Laboratorium Biologi ITSNU Pasuruan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan lima formulasi perbandingan daun B. suaveolens dan S. macrophylla, yaitu F1 (500 g : 0 g), F2 (350 g : 150 g), F3 (250 g : 250 g), F4 (150 g : 350 g), dan F5 (0 g : 500 g) serta pelakuan kontrol negatif (air) dan kontrol positif (insektisida berbahan aktif karbaril 85%), masing-masing diulang tiga kali. Skrining fitokimia dilakukan untuk mengetahui kandungan metabolit sekunder sedangkan uji efektivitas dilakukan untuk mengetahui tiga parameter uji yaitu intensitas serangan, lethal time (LT50), dan mortalitas. Data dianalisis menggunakan Anova dengan tingkat signifikansi 5%. Hasil penelitian menunjukkan bahwa kelima formulasi insektisida nabati mengandung senyawa fenol, tanin, saponin, alkaloid, flavonoid, triterpenoid, dan steroid (kecuali F1 tidak mengandung saponin). Hasil uji efektivitas menunjukkan formulasi F2 dapat mengendalikan H. hampei dengan intensitas serangan sebesar 4,7 lubang gerekan mendekati kontrol positif (4,3 lubang gerekan), lethal time LT50 14,6 jam, dan mortalitas sebesar 53,3%.

Microgreens menjadi inovasi baru dalam pertanian di perkotaan. Kubis bunga ialah salah satu tanaman sayur yang dapat dibudidayakan secara microgreens. Microgreens kubis bunga mengandung sulforaphane yang merupakan senyawa golongan isothiocyanate, yang berpotensi sebagai anti kanker. Konsentrasi senyawa ini dapat berubah sesuai kondisi lingkungan tumbuh, seperti media tanam dan ketersediaan nutrisi. Penelitian bertujuan untuk mendapatkan interaksi terbaik antara media tanam dan nutrisi terbaik untuk meningkatkan kandungan sulforaphane pada microgreens kubis bunga. Penelitian dilaksanakan pada Agustus hingga Desember 2021. Penelitian dirancang secara faktorial yang disusun berdasarkan Rancangan Acak Lengkap. Faktor pertama yakni jenis media tanam (rockwool, cocopeat, kertas tisu dan vermiculite), faktor kedua yakni pemberian nutrisi (tanpa pemberian nutrisi tambahan dan pemberian air kelapa). Hasil percobaan menunjukkan adanya interaksi antara media tanam cocopeat dan air kelapa yang dapat meningkatkan kandungan sulforaphane pada microgreens kubis bunga. Media tanam cocopeat dan vermiculite menunjukan respon terbaik terhadap tinggi microgreens kubis bunga.

Pada tanggal 20 Februari 2022, Sejumlah titik di Kota Makassar terendam banjir yang disebabkan karena hujan lebat yang terjadi di wilayah tersebut. Berdasarkan data curah hujan BMKG, curah hujan yang tercatat pada tanggal tersebut adalah sebesar 166 mm/hari. Dilakukan analisis secara fisis dengan memanfaatkan produk radar cuaca untuk melihat sebaran awan konvektif dan akumulasi curah hujan, serta analisis dinamika atmosfer untuk melihat kondisi atmosfer saat kejadian hujan lebat dan mengetahui penyebab terbentuknya awan-awan konvektif penyebab hujan lebat tersebut. Penelitian ini menggunakan produk CMAX, SRI dan RIH pada citra radar cuaca serta parameter angin, vortisitas, dan vertical velocity dari data reanalysis ERA5 ECMWF. Dari hasil analisisnya dapat diketahui bahwa banjir di Kota Makassar disebabkan karena hujan dengan intensitas lebat yang turun di wilayah tersebut dan diikuti oleh hujan intensitas sedang dalam jangka waktu yang cukup lama. Kejadian hujan sedang-lebat yang menyebabkan banjir di Makassar adalah disebabkan karena awan konvektif yang cukup luas yang menutupi wilayah tersebut. Selain itu, adanya daerah konvergensi angin di sebelah barat daya Kota Makassar yang memicu terjadinya pengangkatan udara ke atas juga menjadi faktor pemicu pertumbuhan awan konvektif penyebab curah hujan yang tinggi di Wilayah Makassar

Polianilin (PANi) merupakan salah satu polimer konduktif yang memiliki sifat unggul dibandingkan polimer konduktif lainnya. Keunggulan tersebut diantaranya adalah stabilitas kimia dan fisikanya sangat baik, reaksi redoksnya bersifat reversibel, memiliki rentang konduktivitas yang lebar dan dapat disintesis dengan metode elektrokimia ataupun kimia. Pada penelitian ini telah dilakukan sintesis PANi dengan metode kimia dan mengaplikasikannya sebagai elektroda pada sistem baterai isi ulang PANi/H2SO4/PbO2. PANi disintesis dari monomer anilin di dalam pelarut 1M H2SO4 dengan menggunakan inisiator amonium peroksidisulfat. Hasil dari sintesis secara kimia diperoleh serbuk PANi dalam bentuk basa emeraldin dengan warna coklat kehitaman. Serbuk PANi selanjutnya dibuat menjadi elektroda dengan cara dilarutkan di dalam n-metilpirrolidinon (NMP) dan dideposisikan di atas substrat aluminium foil. Elektroda PANi selanjutnya dipasangkan dengan PbO2 membentuk sistem baterai isi ulang dengan elektrolit H2SO4. Kajian yang dilakukan adalah menguji kinerja baterai PANi/H2SO4/PbO2 terhadap variasi konsentrasi elektrolit. Hasil pengujian menunjukkan tegangan terbuka sistem baterai tersebut adalah 2,1 Volt. Tegangan kerja baterai bervariasi dari 1,5 Volt sampai 2 Volt pada pembebanan dengan arus konstan sekitar 10 mA sampai 80 mA. Selain itu, berdasarkan hasil pengujian yang telah dilakukan dapat diketahui bahwa semakin rendah konsentasi elektrolit maka semakin kecil rentang dari tegangan kerja baterai tersebut.

Noise merupakan parameter yang selalu muncul dalam setiap proses akuisisi data dari sebuah sensor. Sensor yang digunakan adalah jenis DHT11 dan LM35  yang dipasangkan pada arduino mega untuk memantau suhu ruangan laboratorium sesuai ketentuan ISO 17025. Kalman Filter dapat menghilangkan atau mengurangi noise dari sensor. Keberhasilan Kalman Filter dalam menghilangkan noise ditentukan oleh nilai R yang disebut kovarian noise pengukuran dan Q yang disebut kovarian noise proses. Nilai R dan Q dapat meningkatkan performa Kalman Filter dalam menghilangkan noise. Kalman Filter diaplikasikan pada sensor suhu jenis LM35 dengan keluaran berupa tegangan dan sensor suhu jenis DHT11 dengan keluaran derajat celcius. Selisih penunjukkan data sensor sebelum dan sesudah menggunakan Kalman Filter dengan nilai selisih variansi hasil filter lebih kecil dibandingkan dengan variansi tanpa filter, pada suhu konstan selisih variansi sama dengan nol untuk DHT11 dan 0,14 untuk LM35. Sedangkan pada suhu tidak konstan didapat selisih variansi 0,8 untuk DHT11 dan 0,3 untuk LM35.
