Utilization of Blood Meal, Slaughterhouse Waste and Bio Gas Slurry into Fertilizer

Abstract

In slaughterhouses the burden of waste such as excessive blood volume causes waste process with sewage treatment pond can not work optimally. Blood should be separated and processed into other products. This study aims to prove that blood processing from slaughterhouse produces higher quality organic fertilizer. In this research, the fermentor used in the composting process is biogas slurry. The study used RAL (Complete Randomized Design) with 4 treatments; P0 = without blood meal, P1 = blood meal 6.5%, P2 = blood meal 13% and P3 = blood meal 19.5%. There is no difference between the treatment at fertilizer temperature, pH and C / N. In the treatment application of blood meal by 19.5% in the fourth week of C / N was 12.17 as a requirement for mature fertilizer. The treatment by adding 375 g blood meal on 6 kg livestock feces and 6 kg feed leftover while use biogas slurry as the fermentor was a novel organic fertilizer formula.
