Abstract

Salah satu komunitas peternak sapi perah ada di Dusun Brau, Kecamatan Bumiaji, Kota Batu. Seiring dengan tingginya produk susu yang dihasilkan, limbah peternakan sapi yang dihasilkan juga tinggi. Melalui kegiatan pengabdian masyarakat yang dilakukan pada tahun 2023, anggota Koperasi Margo Makmur Mandiri sebagai perwakilan masyarakat Dusun Brau, Kecamatan Bumiaji, Kota Batu telah mampu melakukan pengolahan limbah peternakan sapi menjadi kompos padat. Kegiatan pengabdian masyarakat tahun 2024 ini, merupakan bentuk kegiatan lanjutan. Tujuan dari kegiatan pelatihan pengemasan, labelling, dan business plan produk kompos padat di desa Brau, peserta dapat: (1) memahami konsep dan teknik pengemasan, labelling, dan business plan yang sesuai dengan standar kualitas dan keamanan produk kompos padat, (2) dapat mengaplikasikan pengetahuan dan keterampilan yang diperoleh dalam kegiatan pelatihan untuk meningkatkan nilai tambah dan daya saing produk kompos padat yang dihasilkan oleh kelompok koperasi Margo Makmur Mandiri di desa Brau, (3) dapat melakukan praktik wirausaha dengan memasarkan produk dalam skala kecil. Dengan demikian, dengan adanya kegiatan pengabdian masyarakat ini, diharapkan dapat memberikan peningkatan pengetahuan dan pemahaman untuk selanjutnya dapat diterapkan oleh peserta dalam memasarkan produk. Kegiatan evaluasi hasil pelatihan dilakukan melalui angket respon yang diisi oleh peserta.

Abstract

Liquid waste from the rambak cracker industry in Tulungagung primarily contains organic compounds that can lead to high levels of Biological Oxygen Demand (BOD). The objectives of this study were: 1) to determine the characteristics of activated carbon from coffee bean skins synthesized from coffee bean skins with different concentrations of H3PO4 activator. 2) to determine the effect of activated carbon mesh size on BOD levels of liquid waste from the Rambak Cracker Industry. Activated carbon from coffee bean skins was synthesized with H3PO4 as an activator at 5, 10, and 20% concentrations, with a 200-mesh size. The synthesis results were compared with liquid waste from the rambak cracker industry to determine the difference in BOD levels. The quality of activated carbon was analyzed in accordance with SNI 06-3730-1995, including water content, ash content, volatile matter content, bound carbon content, iodine absorption capacity, and functional groups. The results of the characterization of 200 mesh coffee bean skin activated carbon obtained water content of 5.00; 5.04; 5.18%, ash content of 3.37; 3.28; 2.62%, volatile matter content of 37.78; 36.67; 35.08%, bound carbon content of 53.85; 55.01; 57.12% and iodine absorption capacity of 998.51; 1011.21; 1023.9 ​​mg/g. The results of functional group identification by FTIR showed that the functional groups detected in activated carbon were aliphatic CH, C=O, C-C, C=C, and C-O. BOD levels before and after contact with activated carbon were 2841.15 and 355.23 mg/L. The study concluded that 200-mesh coffee bean skin-activated carbon with a 20% H3PO4 activator can reduce BOD levels in liquid waste from the Rambak cracker industry by 87.5%.
