Abstract

Anaerobic composting is a composting process that requires oxygen availability. Oxygen is needed by microorganisms to remodel organic material during the composting process. Anaerobic composting is a composting process that does not require the availability of oxygen, but only requires the heat from outside. Skipjack fish (Katsuwonus pelamis) is a medium-sized fish from the family Skombride (tuna), the only species of the genus Katsuwonus. Body length of the largest Skipjack could reach 1 meter and the weight more than 18 kg. The back part is purplish to dark blue and lower abdomen is silver belly and equipped with 4 to 6 black stripes extending to the side of the body. Dcales can only be found on the body scars or coreset and lateral line. Inner and outer part of fish waste from processing were potential to be processed into fertilizer/compost. Generally, fish waste contains many nutrients, namely N (Nitrogen), P (Posforus), and K (Potassium). The purpose of this study was to determine the quality of compost, composting time and number of composts with the addition of skipjack gills. This was an experimental research. In the process of composting the amount of vegetable waste used as much as 40 kg, and skipjack gill about 2 kg. The results of this study showed that the compost produced by the addition skipjack gills for 24 days was 2.7 Kg. While, control group, composting for 24 days produced compost about 2.4 kg. Physically, the color of compost-based skipjack gills was blackish brown, smells of fish gills and has a fine texture like soil. A bit different with compost from control group, the color was light brown, smelling of soil and has a fine texture like soil. It is recommended to further researchers to conduct research by utilizing Skipjack Fish Gills with different composting methods.
