Published: April 2023

This study simulated the characteristics of the fluid flow that passes through the Darrieus turbine before installation and testing were carried out. The purpose of knowing the flow characteristics can determine the profile and position of the maximum speed so that the design and placement of the turbine can be improved. The research method was carried out using dynamic fluid computational simulations in three-dimensional form with steady state conditions, discretization using second-order, with convergent conditions when it reached 10-6. The simulation results show that the position of the flow above the turbine had the lowest value because the fluid flowed relatively without disturbance which caused the velocity to had a value almost the same as the incoming fluid velocity. The fluid velocity increased when it was in line 2 and line 3 or across the turbine. This was due to the turbulence generated by the rotation of the turbine. While the speed on line 4 or below the turbine had a lower value than line 2 and line 3. This was due to the position below the turbine so that the turbine rotation did not have an impact on speed. At the four line positions the velocity increased at Y=0.7 m or when the fluid hits the turbine. This increase in fluid velocity was expected to turn the turbine. The results also included the flow distribution in the form of a streamline in several positions where the flow that was in contact with the channel wall had a low velocity value due to friction with the wall.
Extended Curtin-Hammett principle: Origin of pathway selection in reversible reaction networks under kinetic control
Authors: Takahashi Satoshi , Sato Hirofumi , Hiraoka Shuichi
Published: April 2023

Curtin-Hammett principle works in a reaction sequence where slow irreversible reactions are connected to a fast reversible reaction and determines the product distribution depending only on the relative energy barriers of the two irreversible reactions, resulting in kinetic pathway selection. A basic question is whether Curtin-Hammett principle is applicable to reaction networks composed of reversible elementary reactions, though reversible reactions are generally governed by the laws of thermodynamics. Numerical simulations of model systems where reversible elementary reactions are connected linearly to an initial reversible reaction demonstrate that a metastable state far from equilibrium is transiently produced and that its lifetime is prolonged with increasing the number of connected reversible reactions. Pathway selection based on this extended concept of Curtin-Hammett principle was observed in molecular self-assembly of a Pd6L4 truncated tetrahedron, which supports the idea that the extended Curtin-Hammett principle is a key general concept underlining kinetic control in reversible reaction networks.

To be profitably exploited in medicine, nanosized systems must be endowed with biocompatibility, targeting capability, the ability to evade the immune system, and resistance to clearance. Currently, biogenic nanoparticles, such as Extracellular Vesicles (EVs), are intensively investigated as the platform that naturally recapitulates these highly needed characteristics. EV native targeting properties and pharmacokinetics can be further augmented by decorating the EV surface with specific target ligands as antibodies. However, up to date, works dealing with the functionalization of EV surface with proteins have never considered the biomolecular corona (BC) “variable”, namely the fact that extrinsic biomolecules, mainly proteins, may spontaneously adsorb on the EV surface in biofluids, contributing to determine the biological identity of the EV. In this work, we explore and compare EVs modified with the antibody Cetuximab (CTX) by chemisorption (covalent binding of CTX via biorthogonal click-chemistry) and by physisorption (formation of a CTX corona). Results (surprisingly) indicate that (i) no differences exist between the two formulations in terms of binding affinity imparted by molecular recognition of CTX versus its natural binding partner (epidermal growth factor receptor, EGFR), but (ii) significative differences emerge at the cellular level, where CTX-EVs prepared by click chemistry display superior binding and uptake toward target cells in Fetal Bovine Serum (FBS)-supplied culture medium, very likely due to the higher robustness of the CTX anchorage that resists to the formation of a BC due to interaction with the FBS proteins.

Published: April 2023

Elderly people experience several health problems due to their vulnerability to many diseases, which may affect their mental health. This study aims to assess mental health status among older people and its determinants in rural areas.  It is a cross-sectional study design and involves 412 respondents from 9 villages in the district of Banyumas, Central Java, Indonesia. The data was analyzed by using a logistic regression model. The findings showed that older people with a large number of family members were four times more likely to have a mental health problem than those with a small number. Older people with a history of chronic disease had a threefold greater risk of experiencing mental health problems than older people without chronic disease. Three times as many elderly people with middle economic status reported having mental health issues. Older people with lower education have fewer mental health problems compared to older people who graduated from higher education levels. Health check-up was discovered to influence mental health problems, with older people who did checkups even if irregularly having fewer mental health problems than older people who never did. The study concludes that family size, chronic disease history, economic condition, education, and health check-up are determinants of mental health problems in rural Indonesia.
KAJIAN KARYA ARSITEKTUR C.P. WOLFF SCHOEMAKER DAN HENRI MACLAINE PONT DITINJAU DARI PRINSIP ARSITEKTUR NUSANTARA
Authors: Lawiguna Handoyo , Prajudi Herwindo Rahadian
Published: April 2023

Abstrak - Charles Prosper Wolff Schoemaker dan Henri Maclaine Pont adalah dua orang arsitek berkebangsaan Belanda yang berkarya di Hindia Belanda pada periode 1900-1940. Pada periode ini identitas dari arsitektur Nusantara tengah dicari oleh arsitek Belanda karena perkembangan pemikiran baru arsitektur yang melibatkan kelokalan setempat. Pemikiran ini lahir karena pemikiran yang lama kurang meletakkan arsitektur dengan konteks geografisnya, dimana pemikiran arsitektur “barat” masih mendominasi perancangan. Kedua arsitek tersebut merupakan tokoh yang cukup lantang dalam menyuarakan pemikiran dan idealismenya tentang identitas arsitektur Nusantara sehingga mereka sering berdebat, menginisiasi ide masing-masing untuk mengembangkan identitas arsitektur Nusantara. Keduanya diperkirakan menggunakan pendekatan arsitektur Nusantara namun dari sudut pandang yang berbeda.

Penelitian ini menggunakan metode deskriptif dengan pendekatan kualitatif dengan cara mendeskripsikan objek – objek terpilih dari kedua sosok tersebut  serta menjajaran objek dan dibandingkan dengan teori arsitektur Nusantara oleh Prof. Josef Prijotomo. Data dikumpulkan dengan observasi lapangan serta studi pustaka. Data dikelompokkan berdasarkan variabel penelitian, yaitu tata ruang, struktur – konstruksi – material, dan sosok bangunan. Teknik analisis dilakukan dengan mengaitkan data yang ada dengan teori arsitektur Nusantara serta diintepretasi juga dengan teori lain yang mendukung penelitian untuk membaca arsitektur Nusantara pada objek studi.

Hasil penelitian ini menghasilkan suatu kesimpulan, yaitu dalam karyanya, Schoemaker menafsirkan arsitektur Nusantara dengan pendekatan fungsional dan estetika, dimana fungsional tersebut terkait dengan kenyamanan ruang dan kaitannya dengan iklim lokal. Unsur estetika dibuat dengan menempelkan ornamen yang berkaitan dengan candi. Pendekatan perancangan yang dilakuan oleh Schoemaker adalah modern – lokal, yaitu pemikiran modern dan menambahkan unsur lokal. Berkebalikan dengan Schoemaker, Pont menafsirkan dan mengaplikasikan arsitektur Nusantara lebih menyeluruh. Pont lebih membaca konteks lokal sampai ke akarnya dengan mempelajari sejarah dan budaya agar arsitektur tersebut kontestual dengan alam, sosial, dan budaya lokal. Dalam karyanya, Pont hampir selalu mengaplikasikan teori arsitektur Nusantara, baik pada tatanan ruang, struktur – konstruksi – material, ataupun sosok bangunannya, sehingga bisa disimpulkan pendekatan merancang Pont adalah lokal – modern yaitu mengembangkan dan memperkaya arsitektur lokal dengan kemajuan ataupun pemikiran modern yang bisa mendampingi dan melengkapi arsitektur Nusantara.

Authors: Pratomo Gilang , Abdullah Arif Kamal , Nirwan Histanto Enrico
Published: April 2023

Abstrak - Masjid Salman ITB merupakan salah satu karya arsitektur monumental yang ada di Indonesia Memiliki atap melengkung ke atas dengan ruang sholat yang merupakan area bebas kolom dan hingga sekarang masih dapat berfungsi dengan baik. Struktur sendiri memiliki fungsinya sebagai media untuk menyalurkan beban, namun fungsi struktur dari sebuah bangunan tidak hanya berhenti sampai disitu, tetapi juga sebagai nilai keindahan dari karya arsitektur itu sendiri. Penelitian ini dimaksudkan untuk mengkaji pemanfaatan struktur pada bangunan Masjid Salman ITB yang tidak hanya berfungsi sebagai media penyaluran beban pada bangunan, tetapi juga memiliki nilai estetis. Hasil penelitian dapat menjadi pengembangan keilmuan mengenai perancangan struktur yang dapat meningkatkan nilai estetika bangunan. Perancang dapat memanfaatkan keilmuan ini dalam mengambangkan desain yang berbasis struktur, sehingga kedepannya elemen struktur tidak hanya lagi dipandang sebagai pelengkap bangunan, tetapi memiliki nilai yang sama dengan desain arsitekturalnya. Teori yang digunakan untuk mengkaji estetika struktur adalah teori Bjorn Normann, dimana estetika struktur dapat dinilai dari fungsi mekanikal dan fungsi spasial. Teori tersebut akan menjadi dasar hasil kajian dari buku-buku yang terkait dengan struktur. Penelitian ini merupakan penelitian deskriptif kualitatif dengan pengolahan data yang bersumber dari studi literatur, pengamatan langsung, wawancara, dan simulasi. Analisis dibagi menjadi dua bagian besar. Bagian pertama yaitu, pembahasan struktur terhadap aspek strukturalnya sebagai media penyalur beban. Bagian kedua yaitu, pembahasan struktur terhadap aspek asritekturalnya sebagai wujud, ekspresi, dan elemen pembagi ruang. Pembahasan tersebut mengsilkan temuan yang menjadi dasar penarikan kesimpulan. Dari penelitian ini dapat disimpulkan bahwa, struktur sebagai elemen pembentuk ruang memiliki peran tertinggi dalam mencapai etetika struktur pada Masjid Salman ITB. Selanjutnya, struktur sebagai ekspresi bangunan masih memiliki peran yang cukup tinggi dalam mencapai estetika struktur pada Masjid Salman ITB. Terakhir, struktur sebagai wujud bangunan memiliki peran yang paling rendah untuk mencapai estetika struktur pada Masjid Salman ITB. Adapun hal ini dapat tercapai karena peran struktur sebagai penyalur beban yang memiliki penekanan pada pengoptimalan bentuk struktur dan konfigurasinya.

Published: April 2023

Azospirillum brasilense is a plant growth-promoting rhizobacteria (PGPR) with the potential of being employed as an inoculant to decrease the use of chemical fertilizers. We investigated the ef fect of A. brasilense inoculation on a doubled haploid population derived from Opata / WSHD67.2(257) cross and detected Quantitative Trait Loci (QTL) for seven agronomic traits. The population was segregated, concerning their response to inoculation, into three subgroups: neutral, positive, and negative in a proportion of 60:25:15. A total of 18 major QTL and 83 minor QTL controlled the expression of measured traits. Nineteen QTL showed pleiotropic characteristics; chromosomes 5A, 7A, 7B, and 7D were distinguished as those with QTL controlling four of the seven phenotypes measured. The sequences of nearest markers to major QTL detected synteny to rice sequences that codified for at least 38 candidate genes described and discussed as a first step to understanding the interaction of wheat with A. brasilense.

Olax viridis Oliv (Olacaceae) has numerous ethnomedicinal uses including treatment of breast cancer. The study aimed at evaluating the free radical scavenging and antiproliferative activities of O. viridis whole root and the phytoconstituents responsible for this activity. The sample was defatted using n-hexane(NHE), further extracted by cold maceration using absolute methanol to obtain crude extract which was subjected to liquid-liquid partitioning using dichloromethane to afford the dichloromethane fraction (DCM) and aqueous methanol fraction (MEF). Further precipitation of some aqueous methanol fraction (MEF) using acetone yielded saponin-rich fraction (SRF). Furthermore, acid hydrolysis of the SRF gave the sapogenin-rich fraction (ASRF). These extract/fractions: NHE, DCM.,MEF, SRF and ASRF were used for further investigation. Phytochemical screening of fractions was carried out using standard phytochemical methods. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay was used for antioxidant evaluation in vitro with ascorbic acid as the reference standard for comparison while antiproliferative (AP) activity was by cell viability using yeast (Saccharomyces cerevisae) as a model organism. O. viridis whole root contains carbohydrate, cardiac glycoside, steroids, triterpenes and saponins. The fractions showed dose-dependent activities for DPPH radical scavenging activity with the trend at 1 mg/ml thus: DCM (77.53%) >ASRF(70.60%) >SRF(46.82%) >MEF(33.50%) >NHE(22.83%) and the promising fractions showed median concentration; ASRF(IC50=0.54 mg/ml) >DCM(IC50=0.55 mg/ml). All the fractions showed dose dependent antiproliferative activities ASRF(IC50=3.35 mg/ml) >SRF(IC50=5.10 mg/ml) >MEF(IC50=6.28 mg/ml) >DCM(IC50=7.44 mg/ml). Sapogenin may be responsible for the AP and antioxidant activities as ASRF which contains triterpenidal/steroidal nucleus showed a promising activity compared to other fractions. This study validated the traditional use of Olax species in the treatment of cancer.

Published: April 2023

Autophagy is an intracellular lysosomal degradation pathway and plays a very important role in maintaining intracellular homeostasis. This present study demonstrates the biochemical status and expression of ATG7/LC3 autophagic genes in Melphalan-induced testicular dysfunction. Twenty make Swiss albino mice were maintained under standard conditions of humidity (50 ± 5%), temperature (25 ± 2° C) with free access to food and water. The mice were divided into five groups (n=5 each) and treated by intraperitoneal injection as follows; Group I: vehicle-treated control; Group II: 1 mg/kg/bwt MEP; Group III: 3mg/kg/bwt MEP; Group IV: 5mg/kg/bwt MEP. Histopathological and histochemical evaluation by light microscopy, biochemical assays and sperm parameters evaluation are the various investigation depicted in this study. Result shows a rise percentage of DNA damage and teratozoospermia Index (TZI); decrease of protein concentration and total antioxidant capacity (TAC). Testosterone concentration was depleted. The result also shows a significant decrease of Luteinizing Hormone (LH) level across the groups when compared to the control. This study confirms oxidative stress by increased ROS and MDA levels in the testes of the melphalan-treated mice and defective antioxidants response as evident from diminished activities of antioxidant enzymes. The autophagic gene markers showed an upstream Atg7 gene and downstream of LC3-II/LC3-I ratio. Autophagy is mediated by the expression of Atg7 and LC3 genes and these varying mRNA expression led to autophagic defect.
