Abstract

This research aim to establish a land use change model purposed to figure a spatial ecological equilibrium out from the land used activities. The analyzing of these land use change impacts were adopted from modeling methods, based from system thinking approach. Although the analytical constructions dominated by social sciences, all methodologies were drawn from more than one field of discipline to analyze the nature-society-economy relationships. These interdisciplinary orientation combining concepts has some advantages in recognizing most complex variables in the real world than another functional approaches. The model has verified to validate in villages around the HTI concession area of Jambi Province which is managed by PT Wirakarya Sakti (WKS), and resulted some behavior patterns of land use changed that showed in descriptions as a whole. At last, sensitivity analysis of this model - like a game - has developed the “what if” input variables to predict situation of the future, and has resulted some options of scenario as decision support to the policy system framework.Keywords: Ecologycal equilibrium, HTI pulp concession area, land use change, modeling, system thinking approach, decision support system, Jambi.

Abstract

Given the increasing demand for water, it is necessary to make an effort to anticipate water scarcity through increasing efficiency in an irrigation area. Increasing efficiency requires an increase in the contribution of farmers to finance the repair of irrigation canals. The purpose of this study is to formulate a financing scheme for maintenance of irrigation networks by the state and farmer participation (contribution). Research was conducted at the Cihea Irrigation Area (Cianjur Regency). The method used is system dynamics modeling by observing the parameters studied, including; asset damage, productivity, farmer contributions, public works budget and irrigation efficiency. The results of the analysis with dynamic simulations show that the best scenario to reduce damage to Cihea Irrigation assets is scenario 2 because it reduces the damage by 10.29% and increases the irrigation maintenance index by 0.05 within 10 years. Thus, it is necessary suggest to the government and farmers to increase the contribution and budget for the improvement of the Cihea Irrigation.  Keywords: Asset Damage, Efficiency, Farmer's Contribution, Government Budget, Maintenance
