Comparison of Macronutrient Content to Bio-Fertilizer Produced from Tilapia Offal and Cabbage Scraps in Different Ratios

Abstract

This research study aimed to compare the quality of bio-composted manure produced from tilapia offal together with different ratios of vegetable scraps, all 3 formulas were fermented, with formula 1 using 30 kilograms of vegetable scraps per machine. In 10 kg of tilapia per 10 kg of molasses per 10 liters of water per accelerator. 2 amount 1 sachet (25 g) in the ratio of 3:1:1:1:0.025 formula 2 uses 20 kg of vegetable scraps Per 20 kg of tilapia fish per 10 kg molasses per 10 liters of water per food accelerator. 2, 1 sachet (25 g) in the ratio of 2:2:1:1:0.025 and the formula 3 uses 10 kg of vegetable scraps per 30 kg of tilapia perilla per 10 kg molasses per 10 liters of water. 2 amount 1 sachet (25 g) in a ratio of 1:3:1:1:0.025 By fermentation for at least 21 days, the results showed that Throughout the composting period, the bio-compost temperature was in the range 25.50-30.30 ° C, the pH was in the range 5.5-6.9 the mean nitrogen (N) content of bio-fermented fertilizer formulas 1, 2 and 3 was 3.99%, 4.98% and 5.69%, respectively the mean phosphorus content (P₂O₅) of formulas 1, 2 and 3 was 0.71%, 0.56% and 0.55% respectively the mean potassium content (K₂O) of bio-compost formula 1, 2 and 3 were 0.52%, 0.47% and 0.51% respectively from the comparison it was found that the appropriate formula for bio-composting contains all 3 macronutrients, formula 3 containing nitrogen, phosphorus and potassium at 5.69%, 0.55% and 0.51%. The 3 major macronutrients passed the specified standards of the Department of Agriculture (2014) the standard values ​​for nitrogen, phosphorus and potassium content were not less than 0.5% by weight, respectively.
