TECHNO-ECONOMIC EVALUATION FOR INTEGRATED CULTIVATION OF COFFEE AND STINGLESS BEES IN WEST JAVA, INDONESIA
INTEGRATED CULTIVATION OF COFFEE AND STINGLESS BEES
Keywords:Cascara; green coffee bean; propolis; Tetragonula laeviceps; production cost
: In 2018, Indonesia is the fourth largest coffee producing country globally. Unfortunately, coffee productivity in Indonesia was gradually decreasing between 2017 and 2018. This could reduce the income of coffee farmers and affects the national supply chain of coffee. A biorefinery concept may be applied to raise the economic value of coffee bioindustry. This study investigates techno-economic analysis for integrated cultivation of coffee and stingless bees in Cibodas, Indonesia. Three scenarios were proposed and compared with each other in terms of gross profit margin. The first scenario considered only the production of green coffee bean, whereas the second scenario included additional utilization of coffee pulp by-product from the production of green coffee bean to produce cascara. The third scenario integrated the production of green coffee bean and cascara with the cultivation of stingless bees, Tetragonula laeviceps, using Modular Tetragonula Hives to produce propolis and honey. A techno-economic analysis was carried out for the latter scenario because it had the highest value of gross profit margin (13.7). The production cost of propolis extract from the proposed system was estimated at $15.1/kg with a breakeven point of 1817 kg. The proposed system also produced green coffee bean, cascara and honey as the co-products. A sensitivity analysis was also carried out to determine the influence of production capacity, price of raw materials and employees’ salary on the production of propolis. The employees' salary has a very strong influence on the production cost of propolis followed by price of raw materials and production capacity.
