Abstract

Abstract: Coffee is a strategic commodity that generates promising foreign exchange, where Lampung is the main coffee production centre which continues to increase its production, and more than 80% of it is smallholder coffee. Between 40% and 55% of coffee, production is coffee husk waste, which has not been optimally utilized. Previous research showed that pineapple liquid waste indigen bacteria (Pumakkal) were able to increase acidity and decompose waste organic matter, and the final result was a suitable fertilizer for plant cultivation. This research will solve the problem of coffee husk waste used as compost by utilizing a starter from the previously tested pineapple liquid waste bacteria (Pumakkal). The research was conducted with the first stage of making coffee skin compost with a starter formula of KA (3 bacteria), KB (6 bacteria), KC (9 bacteria), KD (12 bacteria) and KE (15 bacteria), the second stage was to test the quality of the coffee husk compost organic fertilizer followed by a pilot plan application using the best formula. The application uses spinach and chilli plants. The result shows that KC is a model the most appropriate coffee skin compost starter formula.
