Bakasang fermentation of Tilapia fish (Oreochromis mossambicus) waste for production of liquid organic fertilizer (LOF)
Abstract
In previous study, the mixture of manure and sand have been tested successfully as media growth of local Jackfruit seedlings, called Tulo-5 and Beka-3 from Central Sulawesi area. It shows that the organic fertilizers are a good fertilizer to use. One of organic fertilizers in this study is liquid organic fertilizer (LOF) from Tilapia fish (Oreochromis mossambicus) waste. The process to produce LOF used “Bakasang fermentation technology” as a part of a local wisdom in North Sulawesi area. The objective of this research is to produce liquid organic fertilizer using this traditional fermentation technology and to analyze macro nutrient of N, P, K elements and micro nutrients of Zn, Mn, Fe, Cu, Ni, Co elements by spectrophotometry method. The sample was divided into 3 parts for the analysis of the nutrients. The first part was based on macro and micro nutrient content after making the LOF. The second part was based on the kind of local Tilapia fish which were taken from Lindu Lake and Kabonena fresh water fish-culture area. The last, the LOF was made through Bakasang fermentation process with the bacterial feeding and without the bacterial feeding. From the study showed that the nutrient levels in most part of organic liquid fertilizer from the waste of Tilapia fish met the general quality standard levels of the LOF.
