Abstract

Community Service Lectures can bring about new changes in society, one of which is religious and social education, so that there will be an impact from the presence of community service lecture participants. Like the community service lectures held in the village of Gampong Meunasah Baet, Aceh Besar Regency, students as agents of change can make a real impact and contribution to society through this KPM program. In this case, the aim is to determine the impact of community service lectures on religious activities for children and parents in Gampong Meunasah Baet. This community service lecture activity is not just a form of community service but is also useful for students for social interaction, developing personal potential, forming personality or attitudes, and applying knowledge in the field. In this way, this community service course provides a real learning experience that cannot be found on campus. This type of research is field research with a qualitative descriptive approach whose object is Gampong Meunasah Baet and the subjects are children and parents

Abstract

The production of biodiesel from local resources is a strategic approach to support sustainable energy transition. This study aimed to synthesize and evaluate the performance of a heterogeneous catalyst derived from oyster shell-based calcium oxide (CaO) modified with polyvinyl alcohol (PVA) as a binder, for the transesterification of Pliek U oil into biodiesel. CaO was synthesized by calcining oyster shells at 800°C, followed by PVA modification to improve structural stability and catalytic activity. The catalyst was characterized using X-ray Diffraction (XRD) to observe crystal patterns, while the resulting biodiesel was analyzed by Gas Chromatography–Mass Spectrometry (GC-MS) and Fourier Transform Infrared Spectroscopy (FTIR) to identify methyl ester compounds. Physicochemical properties including density, viscosity, acid value, water content, and flash point were also evaluated. Transesterification was carried out at a methanol-to-oil molar ratio of 12:1, catalyst concentration of 2.29% w/w, reaction temperature of 60°C, and reaction time of 90 minutes. The results showed a biodiesel yield of 96%, with dominant components being methyl caprylate, methyl laurate, and methyl caprate. FTIR spectra confirmed the presence of characteristic functional groups of methyl esters. The biodiesel properties met the SNI 7182:2015.
