EFFECTS OF FOREST FIRES ON THE ECONOMY OF THE SUNGAI WAIN PROTECTED FOREST ECOSYSTEM, EAST KALIMANTAN, INDONESIA

Abstract

The problem of fire is that most people carry out burning activities on the grounds that burning costs are cheaper than using tree or grass cutting tools, fires are carried out without good preparation, so that people who burn are often not familiar with fire-fighting techniques, so any incident can occur. In order to provide education to the community and government, the authors conducted a study on the location of Sungai Wain Protected Forest (HLSW), with a total area of 11,245 hectares. Inside there are two rivers, namely the Wain River and the Bugis River. Both rivers are under pressure from ecosystem damage, stemming from forest fires, which have an impact on decreasing the ecological function of land and rivers. To determine the HLSW management policy, in order to reduce the potential for forest fires, the researcher used the Vensim dynamic system, the goal was to obtain an analysis of the effects of fire on water availability in HLSW. Utilization of forest ecosystem products in the form of water availability for human use for drinking water, bathing and other activities. The water needs of the community around HLSW per year is 250,419.24 m3. Water needs of PT. Pertamina per year is 5,256,000 m3, the need for water for firefighting per year is 5,540 m3. The availability of water in HLSW is strongly influenced by the level of rainfall, the amount of land area, vegetation in HLSW and the impact of forest fires and other damage.
