Abstract

Geothermal energy activities are allegedly disturbing Kamojang Nature Reserve by clearing the forest. Actually, the national park according to the Law No. 41 of 1999, must not jeopardize the preservation of germplasm in it. Meanwhile, the utilization of geothermal power plant in the area is also required to meet the electricity demand in Indonesia. Land clearing as one of the activity of exploration and exploitation of geothermal coupled with the increasing of human’s activity inside the forest caused widespread deforestation. Since there is a geothermal energy project inside the Kamojang Nature Reserve, then the aim of this study is to analysis the land cover change at Kamojang Nature Reserve from year 2000 until 2011. The research showed that the type of land cover was dominated by forest for about 4231.3 ha with forest cover percentage around 51.17%. Aside of that, the land cover change caused by exploration and exploitation of Pertamina Geothermal Energy was 60.2 ha (8.90 %), while the changes caused by human activities was 614.46 ha (91.10 %). Based on these results, replanting had been done to overcome the worse effect from each activities. The extent of reforestation and enrichment conducted by PGE was 680.58 ha by involving the society who live in surrounding area.

Abstract

Urban Heat Island (UHI) is a phenomenon exhibited by many worldwide cities. Cities, which exhibit UHI, possess higher air temperature as compared with air temperature in the surrounding areas. However, existing UHI profiles are those occurring in subtropical areas which are, of course, very much different from those in tropical cities. Therefore, the objectives of this study are to describe the UHI’s profile and the role of tree vegetation in controlling and reducing air temperature in a tropical region’s urban areas and, particularly, in DKI Jakarta. In this study, we carried out a spatial analysis of land cover and the distribution of air temperature. In this regard, we based our analysis of the potency of tree vegetation in reducing air temperature in UHI’s profile on the distribution of air temperature in various types of land cover which extended from north to south and from east to west. The ranges of air temperature in land cover in the form of built-up areas were 29.2-39.5 ⁰C, non-tree vegetation 28.6-35.6 ⁰C, and tree vegetation 27.0-35.7 ⁰C. Accordingly, tree vegetation has the highest potential to reduce air temperature and to overcome the phenomenon of UHI.
