Abstract

This community service program aimed to strengthen students’ scientific literacy and environmental awareness through biodiversity-based learning assistance at SMP IT Az-Zahira Khatulistiwa. The identified problems included the limited use of the school environment as a contextual learning resource, the lack of exploratory learning activities in science classes, and the limited utilization of local potential based learning media. The program employed a participatory experiential learning approach consisting of needs assessment, local flora exploration, learning media assistance, contextual learning implementation, and evaluation. Teachers and students actively participated in observing local plants, identifying plant characteristics, compiling flora identification sheets, and developing simple biodiversity-based learning media. The results demonstrated improvements in students’ scientific observation skills, plant classification abilities, collaborative learning, and environmental awareness. The program also produced local biodiversity learning media and an environmental education corner utilized as a sustainable science learning resource. Overall, the program contributed to the development of contextual, participatory, and environmentally oriented science learning.

Abstract

Microbial resistance has traditionally been interpreted through reductionist frameworks emphasizing isolated genetic mutations or clinical antibiotic exposure. This study advances a non-empirical theoretical investigation grounded in integrative conceptual modeling to reconceptualize resistance evolution as a cross-scale, eco-evolutionary phenomenon. A multi-scale analytical framework was constructed to synthesize stochastic mutation supply, horizontal gene transfer, metabolic rewiring, proteostasis regulation, environmental heterogeneity, and anthropogenic chemical pressures into a unified systems architecture. Structured theoretical synthesis and boundary-condition analysis were employed to test internal coherence and cross-context stability. The model demonstrates that resistance emerges as a metastable adaptive state maintained by feedback loops linking molecular mechanisms, community-level interactions, and physicochemical gradients across environmental compartments. Disinfectant exposure, nutrient enrichment, wastewater co-selection, and climate variability were incorporated as dynamic modulators of selective intensity. The resulting framework exhibits explanatory integration, cross-scale generalizability, and predictive plausibility under fluctuating selective regimes. By situating microbial resistance within interconnected ecological and evolutionary systems, this study provides a robust theoretical platform capable of guiding future simulation-based modeling and empirical corroboration within the One Health continuum.

Abstract

Beta-carotene is the major carotenoid compound in red palm oil (RPO) and serves as a provitamin A source; however, it has low stability against environmental factors during storage. This study aimed to analyze changes in beta-carotene content in RPO from Sambas, West Kalimantan, during storage using the UV–Vis spectrophotometric method. Samples were analyzed on day 1 and day 7 using iso-octane as the solvent, and measurements were performed at a maximum wavelength of 446 nm. The results showed that the average beta-carotene content decreased from 188.59 ppm on day 1 to 179.46 ppm on day 7, corresponding to a reduction of 4.84%. This decrease indicated beta-carotene degradation, which was influenced by oxidation, light exposure, and temperature during storage. Nevertheless, the relatively small reduction suggested that the storage conditions were still sufficient to maintain beta-carotene content in RPO. Therefore, RPO should be stored in dark containers, such as amber bottles. These findings are consistent with previous studies reporting that carotenoid degradation in palm oil occurs gradually during storage. Thus, controlling storage conditions is essential to maintain the stability and nutritional value of RPO.
