Abstract

This study examines the impact of facilitation of fresh food distribution permit management including facilitation of distribution permit management procedures and packaging facilitation (type of packaging and packaging label) on improving product safety in Lahat Regency. This research method uses surveys and data analysis from fresh food producers, regulators, and consumers in Lahat Regency. Data were collected through questionnaires to understand the distribution permit process, perceptions of product safety, and the impact of the facilitation carried out. This study also uses a hedonic test to determine the quality of fresh plant-based food including assessments of color, texture, aroma and a Likert test including assessments of uniformity of size, packaging and overall appearance as well as conducting chemical contamination tests in the form of pesticide residue tests and physical contamination tests on PSAT PDUK UMKM samples for rice, coffee beans and pepper spices to determine the safety of fresh plant-based food. The results of facilitating distribution permits, packaging and fresh food sensory towards improving product safety in Lahat Regency for fresh food MSMEs have been running better than in previous years. This can be seen from the increase in the processing of PSAT-PDUK distribution permits in the period from March to July 2024 as many as 15 (fifteen) PSAT-PDUK distribution permit numbers that have been issued from 2 (two) PSAT PDUK distribution permit numbers issued by the Lahat Regency Food Security Service from 2022 to 2023, so that it can be interpreted that business actors really need special assistance from officers who understand the distribution permit processing process and an effective and efficient assistance approach model.

Abstract

Aedes aegypti is the primary vector of dengue hemorrhagic fever (DHF), which remains a major public health concern in Indonesia, including Southeast Sulawesi. Continuous use of chemical larvicides poses risks of resistance development and environmental impacts, thereby necessitating safer alternatives for vector control. This study aimed to evaluate the larvicidal efficacy of ethanol extracts from the leaves and flowers of Lantana camara against A. aegypti larvae. The extracts were prepared through maceration using 96% ethanol, followed by bioassay tests on third- and fourth-instar larvae at concentrations ranging from 10–25 µg/mL. Larval mortality was observed at 24-hour intervals. The results revealed that the leaf extract of L. camaraexhibited higher larvicidal activity than the flower extract, with LC₅₀ and LC₉₀ values of 3.26 µg/mL and 8.31 µg/mL, respectively. Larval mortality increased proportionally with both concentration and exposure time. In conclusion, the leaf extract of L. camara demonstrates potential as an effective and environmentally friendly botanical larvicide for dengue vector control.

Abstract

The estuarine area of Gampong Alue Naga supports high aquatic biodiversity and serves as a primary livelihood source for the local coastal community. However, ecological pressures such as overfishing, mangrove habitat degradation, and water pollution have led to a decline in economically valuable species. The research method used was quantitative descriptive with a participatory approach (participatory action research). Data collection used purposive sampling. The research instruments used were observation guidelines, interviews, and field documentation. Data analysis used quantitative descriptive. The findings indicate the presence of more than 40 aquatic species, including molluscs, crustaceans, and fish, such as Anadara granosa, Scylla serrata, and Penaeus monodon, which hold significant economic value. However, a reduction in size and population was observed in several key species. Community-oriented conservation education integrating local ecological knowledge, sustainable harvesting practices, and value-added seafood processing is recommended to maintain ecological balance and strengthen local economic resilience. Therefore, participatory environmental education plays a strategic role in achieving sustainable ecosystem management and improving coastal community welfare.

Abstract

Low student learning activity in class VII MTsN 2 Banda Aceh on the respiratory system material was marked by minimal student participation in asking questions, discussing, and expressing opinions during the learning process. This condition indicates the need to apply innovative and student-centered learning models and media. This study aims to improve student learning activities through the application of the Problem-Based Learning (PBL) model assisted by audio-visual media. This study uses a Classroom Action Research (CAR) design carried out in two cycles, each covering the stages of planning, implementation of actions, observation, and reflection. The research subjects consisted of 37 seventh-grade students at MTsN 2 Banda Aceh. Data were collected using a learning activity observation sheet covering six indicators, namely visual, oral, listening, writing, mental, and emotional activities. The results showed that the average student learning activity increased from 79% in cycle I, which was categorized as high, to 91% in cycle II, which was categorized as very high. The increase occurred consistently across all learning activity indicators. Thus, the application of the PBL model assisted by audio-visual media proved to be effective in increasing student learning activities in biology learning.

Abstract

White turi (Sesbania grandiflora L.) is a tropical plant belonging to the Fabaceae family that is widely distributed and known for its diverse pharmacological activities. However, the utilization of its stem bark as a source of antifungal agents has been relatively underexplored. This study aimed to identify the phytochemical profile and bioactive compounds of white turi stem bark extract with potential antifungal properties. The sample was extracted using a maceration method with 70% ethanol for 72 hours. Qualitative phytochemical screening was conducted using standard methods, including Mayer, Wagner, Dragendorff, Liebermann–Burchard, and FeCl₃ assays. Further analysis was performed using LC-MS/MS (Agilent 6545 Q-TOF LC/MS System) to identify bioactive compounds. The results revealed the presence of alkaloids, terpenoids, phenolics, tannins, and saponins. LC-MS/MS analysis of the F6 water fraction identified several potential antifungal compounds, including adenine, phenylethyl alcohol, benzenedicarboxylic acid bis (2-ethylhexyl) ester, octadecane, and 2,3-dimethoxybenzaldehyde. These compounds are known to exhibit antifungal mechanisms through disruption of cell membranes, protein denaturation, and inhibition of fungal cellular metabolism. Overall, the findings suggest that white turi stem bark extract has strong potential for development as a natural antifungal agent and as a raw material for plant-based health products.
