Abstract

This study aims to analyze N, P, K, and pH contained in liquid organic fertilizer from goroho banana peel waste (Musa acuminafe L.) in Pulisan Village North Minahasa Regency. This study was conducted from September to November 2025 in Pulisan Village and the Manado Center for Standardization and Industrial Services. The method used was a descriptive method with fermentation for 13 days using two different concentrations of EM4 (Effective Microorganisms), namely 130 ml and 195 ml, each mixed with 500 g of goroho banana peel and 25 ml of stale rice MOL. The parameters observed included N, P, K, and pH content. The analysis results showed the N, P, K, and pH content in the liquid organic fertilizer from goroho banana peel waste (Musa acuminafe L.) in Pulisan Village North Minahasa Regency, at an EM4 concentration of 130 ml, obtained an N content of 0.08%; P <0.01%; K 0.39%; and pH 4.00. Meanwhile, at an EM4 concentration of 195 ml, the content was N 0.13%; P 0.01%; K 0.31%; and pH 3.94. Keywords: banana, goroho, liquid organic fertilizer, peel, waste
