Utilization of Plant Waste as A Seed Source to Anticipate Agriculture Global Environmental Challenges and Increase Robusta Coffee Farmers’ Income

Abstract

Coffee is one of the leading plantation commodities in the world trade area. The utilization of plant waste in the form of water shoots from BP308 robusta coffee is a new innovation in anticipating global environmental changes. The research aims to support seed availability by utilizing wastewater shoots as seed candidates in anticipation of global environmental changes that can provide added value and income for farmers. The research was conducted in the District of Pupuan, Tabanan, Bali. The implementation period is 2 years (2018-2020). This study was designed using a paired experimental design in the form of existing technological innovations and new seed innovations. Data were analyzed using the t test. The results showed that the seeds of existing technological innovations and new innovations were significantly different and not significantly different. Coffee leaf rust disease showed no significant differences in attack rates. Wet weight, total seed weight and shoot oven dry weight were higher in the new innovations respectively 42.14; 51.99 and 40.59%. The added value obtained from wastewater shoots is IDR 10,500.00 per tree. Conversion of added value for each farmer with ownership of 0.3–0.8 hectares (population 300-800) of trees generates an added value of IDR 3,150,000.00 to IDR 8,400,000.00 per year per farmer.
