Abstract

Food security is a fundamental aspect of human welfare, ensuring nutritional adequacy to support daily activities and enhance quality of life. This study examines food security in Malasari Village, focusing on food availability, procurement methods, and dietary patterns. Data were collected through questionnaires, observations, and documentation, then analyzed descriptively using charts, graphs, and narrative presentation. Results indicate that 56% of households rely on private agricultural land, 63% utilize home gardens for food crops, and 66% depend on private livestock for food sources. Staple food consumption predominantly consists of rice (84.06%), followed by cassava (10.14%) and bananas (5.80%). Supplementary food intake includes vegetables (24.18%), fruits (24.18%), fish (20.94%), eggs (10.7%), chicken (9.3%), nuts (9.3%), and meat (1.4%). The findings suggest that Malasari Village exhibits relatively high food security, supported by diversified local food production and accessibility. This study underscores the importance of sustainable agricultural practices and equitable food distribution to maintain community resilience.

Abstract

Mount Sanggabuana with an altitude of 1,074 above the sea level has an exciting and high biodiversity. Still, currently, its status is being sought to officially become a National Park and not many research reports have been found that discuss birds in the area. The purpose of this paper is to determine the diversity of bird species in the Sanggabuana Area, Cintalaksana, Tegalwaru, Karawang, West Java. The research was conducted on 15-17 August 2024 using the point count method. Based on the results of observations, 26 bird species from 16 families were recorded and there are five bird species protected according to the Minister of Environment and Forestry Regulation No. 20 of 2018, one of which is the bido snake eagle (Spilornis cheela) from the Accipitridae. The diversity of bird species in the Sanggabuana area is classified in the medium category, details of the H' value in the primary forest (Jalur Hutan) of 2.54 and in the secondary forest (Jalur Curug) of 2.55. The dominating bird species in the primary forest habitat is Takur tohtor (Psilopogon armillaris) while in the secondary forest is Cucak kutilang (Pycnonotus aurigaster).

Abstract

The Cibubur Urban Forest, designated by the DKI Jakarta Regional Government as a conservation area, serves as a vital ecological patch supporting diverse plant vegetation and associated organisms. This study investigates the composition and diversity of soil arthropods within the forest, focusing on their ecological roles across different habitat types. Field research was conducted in March 2024 using pitfall traps (15 traps per habitat, filled with 70% alcohol) deployed for three days. Specimens were collected from four distinct habitats and classified taxonomically. Results identified six arthropod classes: Arachnida, Chilopoda, Collembola, Crustacea, Diplopoda, and Insecta, with Insecta being the most dominant. A total of 16 orders were recorded, with Collembola, Coleoptera, and Diptera exhibiting the highest abundance, while Mantodea and Isoptera were the least represented. Habitat 1 showed the highest arthropod diversity, whereas Plot 2 had the lowest. Ecological analysis revealed arthropod functions as predators, decomposers, scavengers, herbivores, and carnivores, underscoring their critical roles in maintaining forest ecosystem stability. These findings highlight the Cibubur Urban Forest’s significance as a biodiversity hotspot and emphasize the need for habitat-specific conservation strategies to preserve soil arthropod communities and their ecological services.

Abstract

Moringa oleifera has long been valued in traditional skincare, but its molecular interactions with key aging regulators remain poorly understood. This study elucidates the anti-aging potential of Moringa oleifera bioactive compounds through their modulation of sirtuin proteins (SIRT2, SIRT5, SIRT6), which govern genomic stability and oxidative stress responses. Using computational approaches, we performed molecular docking simulations (AutoDock Vina) on 20 bioactive compounds against sirtuin crystal structures from the Protein Data Bank. Comparative analysis with commercial anti-aging agents (niacinamide, AHA, ceramide) identified three Moringa compounds with superior binding affinities: rutin (-10.7 kcal/mol), quercetin (-8.9 kcal/mol), and chlorogenic acid (-7.9 kcal/mol), all outperforming niacinamide (-6.1 kcal/mol). SwissADME profiling confirmed their drug-like properties, including high oral bioavailability, blood-brain barrier penetration, and minimal toxicity risks. Mechanistically, these compounds demonstrated dual antioxidant and anti-inflammatory capacities, suggesting synergistic protection against oxidative damage and inflammation-driven aging. Our results position Moringa oleifera as a rich source of multitarget anti-aging candidates, combining computational validation with biological relevance to advance natural product-based interventions against cellular senescence.

Abstract

Indonesia's coastal and marine ecosystems, including coral reefs, mangroves, and seagrass beds, play critical roles in maintaining biodiversity and ecological balance while providing essential ecosystem services such as coastal protection and food resources. This study evaluates the health of aquatic ecosystems on Pramuka Island and Kotok Besar Island by assessing macroalgal diversity and water quality parameters. Using a survey method with quadratic transects, we analyzed species composition, Shannon-Wiener diversity index, and important value index (IVI) of macroalgae, alongside measurements of physical (temperature, salinity, brightness, depth, current speed) and chemical (pH, dissolved oxygen) water parameters. Results identified 26 macroalgal species on Pramuka Island and 19 on Kotok Besar Island, with moderate diversity indices (H’=2.64 and H’=2.26, respectively). The dominant species were Halimeda macroloba (Chlorophyta) and Hypnea asperi (Rhodophyta) on Pramuka Island, and Halimeda macroloba (Chlorophyta) and Sargassum binderi (Phaeophyta) on Kotok Besar Island. Water quality across both islands remained within optimal ranges for macroalgal growth. These findings underscore the ecological significance of macroalgal communities as bioindicators and highlight the need for targeted conservation strategies to preserve these ecosystems amid rising anthropogenic pressures.
