Economic assessment and management policy of reservoir environment in development

Abstract

The study was conducted at Ir. H. Juanda Reservoir, Purwakarta Regency. This reservoir is multi-purpose, damming up the Citarum river ( 1957 - 1967). It is a series of reservoirs (cascade) where in the interior part are Saguling and Cirata reservoirs, which require an integrated management. At present, the reservoir is under the management of Perusahaan Umum Jasa Tirta II (PJT II) which used to be called Perusahaan Umum Otorita Jatiluhur (POJ). Currently, the main problem is the decreasing quality of water due to pollution, eutrophication, and damaged irrigation channels. It is thOUght that the uneaten fish feed from more than 8501 floating fish cages (Keramba Jaring Apung - KJA) has decreased water quality. Economic valuation is an important consideration in making a fair decision in managing reservoir resources. The study is aimed to identifying the uses of reservoir and their economic value, learning various conflicts, analyzing the perception of the community around the reservoir on the existence of reservoir resources, and formulating the management policy on utilizing the reservoir resources appropriately in the era of regional autonomy. The result of the study shows that there are 7 uses of the reservoir in form of direct utilization value; optional value and non-utilization value. The total economic value is Rp 160.197.824.439 per annum, with the highest direct utilization value of Rp 72.131.819.815 per annum from electricity, followed respectively by fishery Rp 44.524.512.963, irrigation Rp 27.427.796.000, transportation Rp 3.081.045.600, industries Rp1.477.723.900, and recreation Rp 652.912.510. The lowest value is from utilization of domestic water Rp 29.421.032 which is in fact negative in value. In utilizing reservoir resources, so far there have occurred a number of interest conflicts, especially in irrigation, fishery, and water transportation. In the fields of irrigation and fishery the conflicts have led to relation conflict and data conflict. Level of education plays an important role in influencing a person's perception in viewing reservoir resources. To overcome the different problems and constraints in managing the reservoir, it is necessary to divide management policy program into short-term and long-term programs. The short-term program includes not issuing a permit of making a new unit of KJ A, revitalizing the implementation of regional regulation (Perda, SK Gubernur), spreading waste eating fish, and improving irrigation channels. The long-term program includes improving the transparency in work mechanism and supervision between field officers and the community members concerned, and enhancing the corporation among related institutions in the utilization of the resources in the era of regional autonomy.

Penelitian ini telah dilaksanakan di Waduk If. H. Juanda, Kabupaten Purwakarta. Waduk ini merupakan waduk multi-fungsi yang dibendung pada aliran Sungai Citarum (1957-1967), merupakan waduk cascade (series) dimana di bagian hulu terdapat Waduk Saguling dan Cirata yang memerlukan pengelolaan secara terpadu. Saat ini pengelolaan waduk dilakukan oleh Perusahaan Umurn Jasa Tirta II (PJT II) yang sebelumnya bemama Perusahaan Umurn Otorita Jatiluhur (POJ).
