Abstract

Malaria is an infectious disease caused by Plasmodium protozoan parasites that transmit via the female Anopheles sp. mosquito. Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, and Plasmodium knowlesi are the five Plasmodium species known to infect humans. P. falciparum is the most virulent species, causing the most deaths worldwide. The decrease in efficacy of most antimalarials suggests drug resistance. Therefore, the development of new effective antimalarials, particularly against novel targets, was still required. Cysteine protease falcipain-2 (CPF-2) plays a role in hemoglobin degradation; therefore, inhibiting the activity of this enzyme could be a viable antimalarial target. This study aimed to identify a potential inhibitor for the CPF-2 with PDB ID 3BPF from the ZINC15 database for treating malaria. This study employs a virtual screening workflow with HTVS, SP, and XP docking methods on the Glide Maestro Schrodinger. Based on the glide XP docking score, 10 hit compounds were identified, and their conformational interactions with CPF-2 were compared to the natural ligand (E-64). The binding energy values of hit compounds vary from -7.131 kcal/mol to -8.074 kcal/mol, which is more negative than the E-64 (-6.011 kcal/mol). The three best compounds identified from the ZINC15 database are ZINC000025691540, ZINC000096436101, and ZINC000097797430. All the hit compounds discovered similar interaction with E-64, specifically on the CPF-2 binding pocket residues with Gln36, Cys42, Gly83, Asn173, and His174. All hit compounds exhibit suitable Lipinski rule profiles and are potentially evaluated experimentally as CPF-2 enzyme inhibitor candidates. Keywords: cysteine protease falcipain-2, malaria, molecular docking, Plasmodium falciparum, virtual screening

Abstract

Ficus septica is a plant that has demonstrated significant potential as an anti-inflammatory agent. This study evaluates the anti-inflammatory activity and molecular mechanisms of compounds from Ficus septica, focusing on their interactions with Bovine Serum Albumin (BSA) and Cyclooxygenase-2 (COX-2). The results show that the purified extracts from Kadia and Batalaiworu exhibited better anti-inflammatory activity, with IC50 values of 32.04 µg/mL and 32.06 µg/mL, respectively, compared to the crude extracts, which had IC50 values of 42.07 µg/mL and 42.44 µg/mL. Despite this, Diclofenac Sodium exhibited a significantly lower IC50 value of 7.99 µg/mL. Computational studies revealed that Genistein had the strongest binding affinity to BSA with a binding energy of -7.52 kcal/mol, comparable to Diclofenac Sodium (-7.51 kcal/mol). Furthermore, Ficuseptine B and Septicine demonstrated strong binding to COX-2, with binding energies of -9.51 kcal/mol and -9.45 kcal/mol, respectively, outperforming Diclofenac Sodium (-8.49 kcal/mol). These findings suggest that compounds from Ficus septica, particularly Genistein, Ficuseptine B, and Septicine, may serve as potential anti-inflammatory agents through their ability to bind to BSA and COX-2.

Abstract

Mathematics learning is often considered abstract and less relevant to real life, making it difficult for students to understand the concept. Realistic Mathematics Education (RME) offers an approach that helps students build understanding through real situations. The Peresean tradition with its competition structure and cultural values ​​has the potential to be a concrete and meaningful combination learning context. This study aims to design a realistic mathematics learning design that integrates the Peresean tradition into a combination of materials at the Senior High School level. The main problem behind this study is the low understanding of students towards the combination concept due to the delivery of material that is too abstract and has minimal relevance to real life. The RME approach offers a solution through the use of the real context of the Peresean Tradition which was chosen because it has a competition structure that has the potential to be mathematically modeled in the combination context, such as selecting opponents or compiling match schemes. This study uses a qualitative approach with the type of design research in the development studies category. The research process is limited to the preliminary design stage, which includes context analysis, literature studies, and the development of learning designs. The research results are in the form of a theoretical and contextual culture-based learning design, which is validated reflectively based on RME principles and suitability to the curriculum.

Abstract

Abstract Water is the most important thing that must be available to support human life. For generations, people with habits and cultures have used water sources in their territory to meet their daily needs. However, Lelemer Village experiences a shortage of clean water supply such as drinking, bathing, etc. This problem happened because one of the springs could not maximize distribution to the community. Tumpasan Bara is water runoff from cliff rocks with unstable soil quality, so it is vulnerable to landslides that can pollute and even close water distribution pipes because the spring management infrastructure has not met the standards. Therefore, the purpose of this project is to improve upstream infrastructure so that resources can be spread and support the welfare of the Lelemer village community. Typically done by making strides in the upstream foundation so that clean water can be distributed ideally. Therefore, the benefits of this project expect to anticipate backing the welfare of the Lelemer town community. Abstrak Air merupakan kebutuhan paling utama yang harus tersedia untuk menunjang kehidupan manusia. Secara turun temurun masyarakat melalui kebiasaan, dan budaya memanfaatkan sumber air di wilayahnya untuk memenuhi kebutuhan sehari-hari. Akan tetapi pada perkampungan Lelemer justru mengalami kekurangan debit air baik itu untuk keperluan minum, mandi dan lain-lain. Hal ini disebabkan salah satu sumber mata air, yaitu mata air Tumpasan Bara tidak dapat mereka maksimalkan untuk memenuhi kebutuhan. Tumpasan Bara merupakan limpasan air dari bebatuan tebing dengan kualitas tanah yang labil, sehingga rentan akan longsoran tanah yang dapat mencemari bahkan menutup pipa penyalur air dikarenakan infrastruktur pengelolaan mata air tersebut belum mememenuhi standar. Maka tujuan pengabdian masyarakat ini dilakukan adalah untuk melakukan perbaikan infrastrukur hulu agar air bersih dapat tersalurkan dan mendukung kesejahteraan masyarakat perkampungan Lelemer. Hal ini dilakukan dengan memperbaiki infrastrukur hulu agar air bersih dapat tersalurkan dengan optimal. Sehingga hasil kegiatan pengabdian ini diharapkan dapat mendukung kesejahteraan masyarakat perkampungan Lelemer.
