ABSTRACT

This research is motivated by the increasing volume of organic waste from traditional market activities that can pollute the environment if not managed properly. The purpose of this study is to examine the quality of compost produced from market waste and determine the best treatment based on the amount of raw materials used. The research was carried out for three months at the Agricultural Modernization Implementation Center (BRMP) of West Nusa Tenggara (NTB), with stages including the collection of organic matter, fermentation process, and laboratory analysis. The quality parameters tested included moisture content, C-organic, pH, nitrogen (N), phosphorus (P), potassium (K), and C/N ratio. Five treatments were carried out based on variations in the amount of waste: P1 (5 kg), P2 (10 kg), P3 (15 kg), P4 (20 kg), and P5 (25 kg). The results showed that all treatments met the SNI 7763:2024 standard for C-organic, pH, nitrogen, and C/N ratio parameters, but the moisture content of all treatments still exceeded the maximum limit. The P5 treatment showed the best results with the highest macronutrient content (NPK) of 9.81% and the lowest C/N ratio of 8.95, which indicates that the decomposition process is optimal and the compost is cooked. In conclusion, market waste composting has great potential to be developed as a sustainable organic waste management solution. This research also provides applicative experience for students in applying academic knowledge to real environmental problems.
