Analisis Ketersediaan Bahan Organik Lahan Kebun Kakao Berbasis Sistem Integrasi Tanaman-Ternak Model Zero Waste

Abstract

Nowadays, the management of cocoa field produces organic wastes that have not been utilized maximally. The integration of crop-livestock systems (SITT) with zero waste model is an appropriate alternative in managing and maintaining cocoa field, to increase efficiency and productivity through the use of organic waste. The research aims to determine the amount of organic materials in the cocoa field for cow feed and compost purposes, and to calculate the amount of compost material from those organic wastes and from biogas waste. Methods used in this study consists of several stages, i.e. calculating the amount of foliage waste that has potential to be used for cow feed and compost, calculating biogas waste for compost, and calculating the amount of compost materials. The result demonstrates the potential of organic waste was 169,441 kg/ha/year. From this amount, 27,420 kg/ha/year was used for cow feed, and 142,021 kg/ha/year (fresh foliage) was used for compost which produced dry foliage of 78.509 kg/ha/year. On the other hand, cow feces potential for biogas was 4,380 kg/3cows/year and it produced compost raw materials of 536,55 kg/3cows/year. Thus, the total amount of compost raw materials that can produce compost was 79,045 kg/year.
