Milkfish, Apple and Pineapple Waste as Alternative Liquid Organic Fertilizer

摘要

The surge in milkfish production followed sewage pollution around the processing area. It is necessary to reduce the fish waste as alternatives. This study aims to determine the contents of C organic N P K, Salmonella and its effect on plant. Waste was fermented and added with fruit waste as well as an EM4 bioactivator. Chemical and biological quality analysis on liquid organic fertilizer was done There three compositions in the fertilizer, with apple waste, C contents 11.33%, N 3.38%, 3.39% P, 4.19% K, with pineapple waste C contents 17.26%, N 5.28%, 5.64% P, K 5.85%, and the fertilizer with a mixture of pineapple and apple waste had organic C contents 5.10%, N 2.03%, 2.13% P, 2.46% K. The number of bacteria Salmonella is on 4.23 × 10~1 colonies/ml. The highest organic C content, highest level of nitrogen and highest potassium content was liquid organic fertilizer with pineapple fruit The fertilizer in the capsicum plant (Capsicum frutescens) was performed the highest content of NPK highest.
