Abstract

Uric acid is produced in tissues containing xanthine oxidases, like the small intestine and liver, as involved in the purine metabolism of adenine and guanine. High uric acid levels cause damage to cell membranes due to the lipid peroxidase chain reaction. Foods containing high purines will activate the xanthine oxidase (XOD), causing an increase in free radicals. Free radicals attack polyunsaturated fatty acids (PUFA) by forming lipid peroxides. PUFA molecules contain multiple double bonds, which make them susceptible to oxidation by reactive oxygen species (ROS), such as free radicals. PUFA will be broken into simple compounds such as pentane, ethane, and aldehydes, leading to malondialdehyde (MDA) formation. High MDA levels illustrate the process of cell membrane oxidation leading to cell membrane damage. Hyperuricemia is often treated using synthetic drugs such as allopurinol; however, it can cause side effects. Some people will choose medicinal plants with minimal side effects. Green tea (Camellia sinensis L.) contains many polyphenol antioxidants, especially flavonoids, which also have a strong antioxidant effect by exerting multiple mechanisms such as inhibiting several enzymes, including antiphospholipid peroxidase, free radical scavengers, metal bonds, and xanthine oxidase (XOD). Statistical analysis results proved that green tea with a dose of 600 mg/kg BW could decrease the level of MDA in the liver by 84.87% (p 0.01) and reduce the activity of XOD by 35.36% (p 0.01). Taken together, green tea can improve liver histopathology.

Abstract

This study examines the differences in the legal consequences of nominee arrangement in the Basic Law of Agaria and the Supreme Court Circular Number 10 of 2020 which will be viewed from the perspective of certainty and justice. The deed of nominee arrangement cannot be separated from the notary since only a notary can formulate it in the form of an authentic deed, so the author also examines the notary's role in minimizing the making of a deed of nominee arrangement. This research is normative and evaluative and uses primary and secondary legal materials. The technique of collecting legal materials uses the library study technique, and the technique of analyzing legal materials uses the deductive syllogism method. The study results show that the Basic Law of Agaria provides more justice and legal certainty than the Supreme Court Circular, so the rules on nominee arrangement in the Supreme Court Circular shouldn’t be enforced. The role of notary in minimizing the rampant nominee arrangement cannot be separated from the support and role of the Notary Supervisory Board to guide a preventive and repressive effort to strengthen a notary's morals and integrity patterns. Furthermore, this writing hopes that the Supreme Court revokes the rules relating to nominee arrangement. Another hope is that notary can actively prioritize their moral integrity to provide legal counseling and reject the creation of deeds containing nominee arrangement.

Abstract

This research aims to produce N/S-doped Carbon Electrode derived from paper waste (NSCEp) for Electric Double-Layer Capacitor (EDLC). The paper waste holds potential as raw material for carbon production because of its high cellulose content, abundance of availability, and low price. To enhance the electrical performance of the carbon, an activation step was conducted, followed by double doping with nitrogen and sulfur using thiourea. The NSCEp result was analysed to examine its specific diffraction peaks, crystallinity, morphology, and elemental contents. The NSCEp powder was then mixed with dispersant to produce a homogeneous slurry for the electrode film. The EDLC was assembled in a sandwich-like structure, with sodium hydroxide (NaOH) solution impregnated in a separator between the carbon film electrodes. The EDLC assembly was conducted under an argon atmosphere in a CR2032 coin cell. The results found that the NSCEp provides a high electrical conductivity of 1.21 x 102 S/cm. The prepared EDLC achieved the specific capacitance value of 39.555 F/g as determined by cyclic voltammetry (CV) analysis. Furthermore, the EDLC demonstrates high initial charge-discharge capacities of 300.56 mAh/g and 248.88 mAh/g, respectively, at a current of 0.015 A/g. The capacity remains stable for up to 300 charge-discharge cycles.

Abstract

Katalis logam transisi periode pertama (Fe, Co, Ni, Cu, atau Zn) berbasis Hydrogen Zeolite Socony Mobil – 5 (HZSM-5) merupakan katalis yang menjanjikan untuk berbagai macam reaksi. Pada penelitian ini akan dipelajari keperiodikan aktivitas dan kestabilan struktur katalis tersebut pada reaksi cracking anisol. Uji katalitik dilakukan dengan menggunakan reaktor semi alir. Produk dari hasil proses cracking anisol dianalisis menggunakan kromatografi gas-spektra massa (GC-MS), kemudian karakter katalis bekas seperti kristalinitas dan komposisi fasa dianalisis menggunakan X-ray diffraction (XRD), sedangkan luas permukaan dan porositas dianalisis menggunakan surface area analyzer (SAA). Hasil penelitian menunjukkan bahwa tidak nampak kaitan antara sifat periodik unsur dengan aktivitas katalitiknya. Karakter setiap katalis yang telah digunakan mengalami sedikit perubahan pada komposisi fasanya, terutama katalis Fe/HZSM-5 dan Co/HZSM-5, sedangkan luas permukaan dan porositasnya mengalami penurunan.

Abstract

A study on graphene defects for hydrogen storage has been successfully conducted using the Density Functional Tight Binding (DFTB) approach. The research aimed to modify solid materials for hydrogen storage. A 4 × 4 × 1 unit cell was used as the basis, while the supercell used for sampling was enlarged to 40 × 40 × 1. The analyzed data included changes in Density of States (DOS), Fermi level shifts, electronic band structures, formation energy, adsorption energy, and isosurfaces for each graphene orientation. It has been observed that modifying the surface structure of graphene can alter the electronic properties of graphene. This is indicated by shifts in DOS intensity, characterized by increased electronic intensity around the Fermi level total density charge different. The interaction energy between graphene and hydrogen gas has been determined to be -0.0155 eV for H-epoxy graphene, -0.4941 eV for H-monovacancy graphene, and -0.0424 eV for HN-monovacancy graphene. The presence of the vacancy increase the potential to adsorp hydrogen.

Abstract

Local wisdom in Indonesia is a valuable cultural heritage. To preserve it, it can be introduced through school education, one of which is in physics education. Several researchers have studied local wisdom-based physics education in traditional games in depth, but no specific focus on the Egrang game has been found. Therefore, this study aims to analyze and identify the physics concepts found in the traditional game of stilts as an effort to integrate local wisdom into physics education. The research method used is a Systematic Literature Review (SLR) using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) design. Data was obtained from the Google Scholar database using the keyword “traditional Egrang game.” From the 1,270 documents identified, after screening based on inclusion and exclusion criteria, 7 articles were obtained that were suitable for analysis. The data was then analyzed descriptively to identify and classify physics concepts in the traditional Egrang game. The results of this study indicate that stilts are related to the physics concepts of work and energy, namely, mechanical energy consisting of kinetic and potential energy. Identification from the literature review also found other concepts such as rigid body equilibrium, balance, weight, and gravitational force. The results of this study confirm that stilts can strengthen students' understanding of physics concepts and the development of teaching materials in physics learning.
