Biomi Technology Offers Solution to Livestock Waste Pollution in Tabanan, Bali

Environmental pollution caused by livestock waste in Tabanan Regency, Bali, is seeing a potential solution through the use of an innovative biomi formula. The technology is being introduced to effectively process cattle waste while maintaining rural sanitation standards. Academic I Nyoman Kaca from the Faculty of Agriculture, Science, and Technology (FPST) at Warmadewa University explained that the application of this technology is expected to reduce odour pollution and contamination, which have long been challenges for local farmers. Through a community-based approach, the use of biomi also enhances the economic value of waste by converting it into high-quality organic fertiliser. “The application of this biomi technology is designed to help farmers overcome hygiene issues in their pens and surrounding areas, so that the presence of livestock farms no longer disturbs the comfort of residents,” Nyoman Kaca stated in Denpasar on Friday (19/6/2026). The main advantage of biomi technology lies in its ability to significantly accelerate the decomposition of organic matter in livestock waste. Whereas conventional composting can take months, the microorganisms in the Biomi formula drastically shorten the maturation time, making the process far more efficient. Beyond speeding up fertiliser production, this biological formulation actively binds ammonia, drastically reducing the pungent smell of cattle dung and urine from the initial application. The end result of this decomposition process is a nutrient-rich organic fertiliser that is highly stable, free from harmful pathogens, and ready to be used to improve soil fertility for horticultural farming. The programme is centred on the Amertha Sari II Livestock Farmer Group in Banjar Kesiut Kangin, Kesiut Village, Kerambitan District, Tabanan Regency. This group serves as a pilot model for a sustainable, community-based waste management system. The global-scale programme is the result of cross-border collaboration. The FPST at Warmadewa University partnered with two foreign universities, Universiti Teknologi MARA (UiTM) in Malaysia and Pampanga State Agricultural University (PSAU) in the Philippines. The involvement of these international partners brings diverse perspectives and new expertise in mapping environmentally friendly livestock waste management that is also productive for horticultural agriculture in Bali. Through the integration of technology and education, waste that was once an environmental burden is now being transformed into an economic asset for farmers in Tabanan.
