“…The quality of organic matter largely determines the speed of the process of decomposition and mineralization of organic matter. Low Corganic levels in organic fertilizers indicate that microorganisms use a lot of carbon in raw materials for their growth and indicate that microorganisms are working more in number [18]. The results of the research [19] show that in the decomposition process there is a decrease in C-organic content, this is due to the addition of microorganisms that need organic carbon as food.…”

Livestock waste such as feces, urine, and leftover feed left without further treatment can harm the environment in the form of air, water, and soil pollution. Therefore, efforts are needed to process livestock waste into useful products in the form of organic fertilizers. Livestock waste that has the potential to be a source of organic fertilizer is etawa goat waste. Etawa goat feces processing technology in the form of bokashi fertilizer made from fermented livestock and agricultural wastes using EM-4. Bokashi fertilizer contains a variety of essential macro and micronutrients needed by plants and can improve soil fertility and quality. This research aims to determine whether bokashi fertilizer with the main ingredients of etawa goat feces has various formulations, specifically P1 (bokashi pure etawa goat feces), P2 (bokashi etawa goat feces with roasted husks), P3 (bokashi etawa goat feces with tea dregs), and P4 (bokashi feces etawa goat with sawdust) has physical and chemical characteristics according to SNI organic fertilizer (Indonesian National Standard-2011). This research method uses a descriptive research design. The research data were obtained through laboratory analysis of various formulations of etawa goat feces bokashi fertilizer samples and compared the results with the solid organic fertilizer standard SNI (Indonesian National Standard)-2011. Based on the results of the research showed that etawa goat feces bokashi fertilizer with various formulations, specifically P1 (bokashi pure etawa goat feces), P2 (bokashi etawa goat feces with roasted husks), P3 (bokashi etawa goat feces with tea dregs), and P4 (bokashi feces etawa goat with sawdust) has physical and chemical characteristics that are following the solid organic fertilizer standard SNI-2011, except for the C/N ratio and the number of macronutrients (N, P, and K).
