Pemetaan Potensi Pembangkit Listrik Tenaga Mikrohidro di Pulau Jawa Menggunakan Sistem Informasi Geografis.

Abstract

Java Island is the most populous island in Indonesia, which is 833 people/km2 and the population reach about 58% of Indonesia total polulation. Population and economic growth also resulted in annual electricity consumption increased by 9%, which can lead to energy crisis. The objective of this research is to mapping out the locations that have potential for build the microhydro power plant based on predetermined criteria. The criteria are determined based on the literature stating that minimal slope of 45° and a head of 2 meter are located on river flow that have minimal discharge 0.25 m³/s. Head and minimal slope were analyzed using 30 of ASTER DEM data. The discharges are estimated by using the data from PDA and land use data with debit balance equation and weighting coefficients of runoff. The result from this research can identify 90 point of potential micro hydro with power 2.04 MW and all categories of hydroelectric power plant amounted to 20.26 MW.
