Development of technology vermicompost production for the coffee plant Industry

Abstract

The aim of this study was to convert skin coffee (SC) amended with green waste (GW) and biochar(B) into vermicompost and evaluates their effects on the plant growth coffee. Biochar is a carbon rich product made from the rice husk pyrolysis process at 450°C, green waste eq branch cuttings and leaves from in the garden Universitas Negeri Jakarta and skin coffee from Cibulao coffee farm Bogor, Indonesia. Biochar was mixed with SC and GW in different proportion i.e., 6%,8% and 10% b along with control and allowed to pass through earthworm guts during two months. Vermicompost was characterization with SEM EDX and chemical content. The 8% biochar addition rate achieved maturity of vermicomposting and resulted in the highest quality vermicompost based on parameters such as organic C, C:N ratio, total N, P, K content and pH, were compared to a vermicompost as control. in the cultivation of plant growth, physiological parameters and morphology plant coffee growth such as number of leaf, heigh plant, steam diameter and shoot dried weight.
