Abstract

Transforming household organic waste (such as leftover food, fruits, vegetables, and other organic materials) into eco-enzymes represents a pioneering community service initiative in Luthu Lamweu Village, Sukamakmur District, Aceh Besar, Aceh Province, Indonesia. This project aims to enhance environmental awareness and improve community welfare. The villagers of Luthu Lamweu possess significant potential in converting organic waste into valuable products. The research methodology employed a participatory approach, actively engaging the community in all stages, including awareness campaigns (socialization), training sessions, technical support for eco-enzyme production, and evaluation. The strategy involved collaboration with village authorities, facilitated through the Program Bakti Mahasiswa Teknik (PBMT) and lecturer-led community service (PkM) to ensure program sustainability. The community service outcomes indicated a substantial increase in the communitys knowledge, interest, and skills in managing household organic waste into eco-enzymes, with a success rate of 96.25% (rated from sufficient to very good). Furthermore, the program positively impacted the villages environmental quality by converting organic waste into valuable eco-enzymes.

Abstract

Pemanfaatan limbah organik sebagai sumber energi alternatif menjadi solusi yang penting dalam menghadapi permasalahan limbah dan ketergantungan terhadap bahan bakar fosil. Desa Cot Mesjid, Kecamatan Sukamakmur, Aceh Besar, memiliki potensi besar dalam pengelolaan sampah organik yang dapat diolah menjadi biobriket sebagai sumber bahan bakar alternatif. Program pengabdian masyarakat ini bertujuan untuk mengidentifikasi potensi limbah organik, memberikan pelatihan pembuatan biobriket, serta menganalisis manfaat lingkungan dan ekonomi dari pemanfaatan biobriket. Metode pelaksanaan terdiri dari tahapan sosialisasi, identifikasi bahan baku, pelatihan produksi biobriket, serta monitoring dan evaluasi efektivitas penggunaan biobriket. Pelatihan dilakukan dengan pendekatan praktik langsung, melibatkan masyarakat dalam setiap tahap produksi mulai dari pengumpulan bahan baku, proses pirolisis, penghalusan arang, pencampuran dengan bahan perekat, pencetakan, hingga pengeringan biobriket. Evaluasi dilakukan melalui observasi, wawancara, dan angket kepada peserta pelatihan. Hasil menunjukkan bahwa masyarakat merespons positif program ini, dengan peningkatan pemahaman mengenai pemanfaatan limbah organik dan kemampuan produksi biobriket secara mandiri. Selain itu, biobriket yang dihasilkan memiliki efisiensi pembakaran yang tinggi dan dapat mengurangi ketergantungan terhadap bahan bakar fosil. Potensi pengembangan usaha biobriket juga terlihat dari minat beberapa kelompok masyarakat dalam memasarkan produk ini secara lokal. Dengan hasil yang positif, program ini dapat menjadi model bagi daerah lain dalam mengembangkan pemanfaatan limbah organik sebagai sumber energi alternatif yang ekonomis dan ramah lingkungan.

Abstract

This study investigates the effects of dual activation methods, including physical and chemical processes, on the characteristics of diatomaceous earth (DE) for the purpose of controlling heavy metal concentration in acid mine drainage. The DE is subjected to physical activation through calcination at 750 oC for 60 minutes, followed by chemical activation using 1N HCl at 80 oC for 24 hours under magnetic stirring. The resulting adsorbent is then characterized using XRD, SEM-EDX, and BET instruments. The analysis reveals that the dual activation methods increase the silica content and eliminate impurities in the DE, leading to a more amorphous structure with decreased crystallinity. The physical activation increases the surface area, while the dual activation process reduces the surface area and increases pore size. These findings provide valuable insights into the adsorption capacity of DE for reducing heavy metals in acid mine drainage.
