Abstract

Unit of Water Treatment and Composting Plant of PT. Djarum Oasis Kretek Factory Kudus is a waste water management systems produce clean water and compost. Waste water treatment unit processes Waste Water Treatment Plant produces sludge reaches 500 kg/day in dry or weights reach 2-2.5 tons/day in the wet weight. This type of research using this type of comparative, descriptive study where a population of the research was all compost produced by composting plant Water Treatment Unit and Composting Plant of PT. Djarum Oasis Kretek Factory Kudus with samples windrow compost and vermin compost with a weight of 1 kg each. The results of the examination of the physical quality of the windrow compost obtained 21.33% water content, temperature 32⁰C aircraft, color dark brown, smelling the ground. The results of the examination of the physical quality of the vermin composting gained 24.15% water content, temperature 30⁰C, blackish brown color, smelling the ground. The results of the examination of the quality of the compost windrow chemical gained 25.50% of organic C, total N 1.61%, P₂O₅ 0.51%, K₂O of 1.34%, macro nutrient levels (N Total+P₂O₅+K₂O) of 3.46%. Vermin kompos chemical quality inspection results gained 23.76% of organic C, total N 1.26%, 0.92% P₂O₅, K₂O of 0.86%, macro nutrient levels (N Total+P₂O₅+K₂O) 3.04%. The results of the examination of the physical and chemical quality of windrow compost and vermin compost there are a few parameters that do not meet the requirements as organic fertilizer composting in accordance with technical requirements a minimum of organic fertilizer from waste water treatment Installation Industry number: 70/regulation of the minister of agriculture/SR 140/10/2011 (Annex I. 3) about biological fertilizers, organic fertilizers, and improve the soil, so that the windrow compost and vermin compost known simply as repair soil.
