Abstract

This community service initiative aims to enhance awareness and encourage active participation among the residents of Peunaga Cut Ujong Village, Meureubo Subdistrict, West Aceh Regency, in environmental conservation efforts through mangrove planting. Located in a coastal area vulnerable to erosion and exposed to air pollution due to coal-burning activities, this village faces significant environmental challenges. Employing an educational and participatory approach, the program involved raising awareness about the ecological functions of mangroves and conducting direct planting activities in a mangrove forest area approximately 100 meters from the shoreline. The outcomes of the initiative indicated a positive response from the community, demonstrated by increased environmental awareness and active involvement in conservation efforts. Mangrove planting is expected to function as a coastal protection barrier, an air pollutant absorber, and a potential site for ecotourism and aquaculture development. This initiative highlights the importance of synergy between academia, the local community, and the industrial sector in creating sustainable environmental solutions. Continuous evaluation and the replication of similar programs are strongly recommended to enhance their long-term impact.

Abstract

The degradation process of food waste with anaerobic digestion technology can be performed in a single-stage bioreactor. This study examined the effect of a single-stage digester configuration on biogas production using cow manure inoculum at a tropical ambient temperature of 27.3 ± 1 °C. The single-stage digester had a working volume of 369 L. Feeding food waste into the bioreactor was carried out 5 times a week with a maximum OLR of 0.8 Kg/day. The average biogas production was 90.6 L/day. Also, the results showed that applying a single-stage digester configuration in degrading food waste could produce a carbon recovery of 71.41% in the carbon mass balance analysis. These results indicate that the single-stage digester configuration performed well. The single-stage digester configuration gradually increased biogas production.

Abstract

Pertumbuhan populasi global mendorong peningkatan kebutuhan energi yang menjadi tantangan serius bagi pembangunan berkelanjutan. Indonesia, sebagai konsumen energi primer terbesar kelima di Asia Pasifik, menghadapi tekanan terhadap ketahanan energi, khususnya di sektor rumah tangga. Di tengah dominasi energi konvensional, Indonesia memiliki potensi besar dalam energi terbarukan, salah satunya biomassa dari limbah peternakan sapi. Limbah ini mengandung bahan organik tinggi yang dapat dikonversi menjadi biogas melalui teknologi biodigester, sekaligus mengurangi pencemaran lingkungan dan mendukung kemandirian energi masyarakat. Penelitian ini bertujuan untuk merancang dan membangun biodigester skala kecil yang sesuai dengan kondisi lokal di Universitas Teuku Umar (UTU), Aceh. Biodigester dirancang sebagai reaktor anaerob tertutup yang mengubah limbah kotoran sapi menjadi biogas dan pupuk organik. Melalui pendekatan berbasis komunitas, teknologi ini diharapkan dapat mendukung pengelolaan limbah yang ramah lingkungan dan meningkatkan kemandirian energi masyarakat. Selain itu, proyek ini menjadi sarana pembelajaran aplikatif bagi mahasiswa UTU dalam bidang teknik mesin, lingkungan, dan energi terbarukan. Hasil penelitian menunjukkan bahwa biodigester berpotensi menjadi solusi strategis dalam pengelolaan limbah dan penyediaan energi alternatif yang berkelanjutan.
