Abstract
Water was considered as a strategic resource in agricultural production process. Unlike other input such as seed, fertilizer and pesticide which role^s dimension was relatively limited to the certain production, Irrigation water has a wider role, not only affecting agricultural productivity but also affecting agricultural commodity farming spectrum. The water irrigation performance, therefore, not only determine the agricultural production growth, but also agricultural commodity business in wider aspect. Dryland most characteristic was the limitation of water for agricultural production process. As a consequences dryland mostly can only be planted one season a year, during rainy season. In order to increase the productivity of dryland Government has built several pumping/ Ground water irrigation scheme which management was delivered by person elected by farmers organization members. Pumping water irrigation tariff was determined by per hour operational cost based of irrigation services. This research was aimed to: 1) analyze the operational cost based tariff of pumping water irrigation, 2) analyze Marginal Product Value (MPV) as a Basis of Commodity Based Pumping Irrigation Scheme Tariff, and 3) analyze the benefit that farmers gain from pumping irrigation services. The results indicate that the operational cost of pumping irrigation service resulting in 34,000 - 60,000 IDR tariff per hour of irrigation services. The cost based was Applied regardless to the commodity planted. The Value of Marginal Product based Tariff approach indicate that additional 1 m3 of water can increase 0.248 kg of Corn, 0.115 kg of Soybean, and 0.107 kg of Peanut and creating Rp 372/m3 (Rp 2 611 812/ha) from Corn farming, Rp 693/m3 (Rp 2 235 618/ha) from Soybean farming, and Rp 1501/m3 (Rp 4 762 673/ha) from Peanut framing.
