TEKNOLOGI GREEN ENERGY BIOSAM DAN BIO-SLURRY DARI SAMPAH ORGANIK

Abstract

This innovation has led to the development of the BIOSAM digester, which efficiently processes organic waste into renewable energy through an anaerobic process, producing high-quality biogas and bio-slurry as byproducts. Bio-slurry is a nutrient-rich sludge that serves as a high-quality organic fertilizer enriched with humus. It not only provides essential nutrients but also contains probiotic microbes that enhance soil fertility and health, improving the quality and yield of crops, vegetables, fruits, and plantation crops.Users need to understand proper reactor maintenance to ensure biogas production remains efficient, energy-saving, safe, and environmentally friendly. The processing of underutilized organic waste offers a solution to issues such as odor, air pollution, and health risks caused by waste burning. The BIOSAM digester is designed with state-of-the-art technology to process household organic waste using cow manure as a starter. This reactor has the potential to be utilized by various entities, such as village-owned enterprises (BumDes), the food industry, NGOs, and environmental CSR programs, enabling easy waste management, reduced operational costs, and increased productivity.Tests on liquid bio-slurry fertilizer have shown its potential for plants and livestock feed, with organic carbon content ranging from 0.08–0.62%, a C/N ratio of 0.16–22.85, pH levels of 7.4–8.2, and macro (N, P, K) and micro (Mn, Zn, Mo, B) nutrients that support plant growth and livestock health. Dried bio-slurry, with a dry matter content of 18.6–43.6%, ash content of 22–33.2%, crude protein of 10–12.6%, crude fiber of 27.8–35%, and energy of 3,035–3,284 Kcal/kg, shows great potential as livestock feed. Water quality tests in fish ponds indicate that using dried bio-slurry in feed does not affect water quality, reduces pollution risks, and improves fish farming efficiency.
