## Abstract
This study aims to evaluate and compare the nutrient content of organic fertilizer originated from shrimp pond waste, which use commercial decomposers and indigenous decomposers. The research was carried out at Research Institute for Coastal Aquaculture and Fisheries Extension (RICAFE), Maros, South Sulawesi, Indonesia. The study used a completely randomized design (CRD) with four treatments and 3 replications. Solid waste of shrimp pond with several types of bio activators was used in this study. The treatments were types of bio activators, namely: BIO (A), TR-04 (B), EM4 (C) and decomposer bacteria isolated from pond waste ISO (D). The composting time lasted for 30 days. Observed variables were macronutrient content (C-Organic, N-Total, C/N ratio, P2O5 and K2O) and microelements (Fe, Mn, Zn, Cu) as well as temperature and pH of the composting media. The results showed that different bio activators significantly affected the quality of pond waste organic fertilizer (p <0.01). Nutrient contents (C-Organic, C/N ratio, P2O5, and K2O, Fe, Mn, Zn, Cu) were not significantly different (p> 0.05), while N-total value was significantly different (p <0.05). The quality of produced compost in all bio activator treatments (BIO, TR, EM, and ISO) met Indonesian National Standard (SNI) 2004 and standard of regulation of the ministry of agriculture republic of Indonesia (PERMENTAN) 2019. This study can be an alternative for treating waste of shrimp culture industry.
