Abstract
This research is aimed to study the production cost for determining feasibility and return of investment (ROI) of farming and farmer income based on the crop yield in the Pante Lhong technical irrigation system. These system performances were evaluated using measured/rewarded/collected internal and external indicators that covered different aspect of evaluation. The Rapid Appraisal Process (RAP) is a visual assessment tool was used to evaluate the external indicators performance. The external indicators were crop yield and production cost. The data of crop yield and production cost were collected from the farmers in the three regions which were upstream, middle stream and downstream. Data were collected through field observation and face to face interviews with the irrigation staff and the farmers. The production cost data were calculated based on the land preparation cost, growth stage cost and harvesting cost. In the crop yield indicator, the average maximum productivity was 3.91 ton/ha and the income generated was Rp.11.730 million rupiahs/ha (US$ 1289/ha). The total production cost of the Pante Lhong technical irrigation system was Rp. 4.126 million rupiahs/ha (US$ 453.50/ha) and hence in term of return of investment (ROI), it is still profitable and feasible to be developed for the farmers.
