Abstract

ABSTRACT This study aims to determine the level of erosion hazard through erosion prediction by USLE method and Geographic Information System (GIS) at Water Catchment Area (WCA) Danau Wisata Bandar Kayangan. This research was conducted at WCA Danau Wisata Bandar Kayangan, Limbungan Village, District Rumbai, Pekanbaru. The research data was collected by survey method. Secondary data collection includes a slope digital map, land cover map, rainfall data, and soil type map of WCA Danau Wisata Bandar Kayangan. While the primary data is done by field checking to know land use pattern and soil type around WCA  Danau Wisata Bandar Kayangan. The result shows that the erosivity index (R) is 108. The soil erodibility index (K) in Podsolik Merah Kuning (PMK) is 0.166. Slope length index (LS) on slope <8% flatland (20), 8 - 15% ramps (15), 16 - 25% slightly steep (10). Crop management and soil conservation (CP) index covers settlement (1), Bush / 0.01), plantation (0,02), and lake (0,01). The result of overlay of rainfall maps, soil type, slope class, and crop management and soil conservation obtained 46 land units at WCA Danau Wisata Bandar Kayangan. The highest Erosion Hazard Index (EHI) is found on land unit 45 of 358 on residential land cover. The largest potential erosion on land unit 44 with soil loss is 41,189.45 ton / ha / yr. Level of EHI in WCA Area of Danau Wisata Bandar Kayangan includes Class EHI 1: Very Light area of 32,627 ha; EHI Class 2: Lightweight of 59.86 ha; Class EHI 3: Medium area of 247.52 ha; Class EHI 4: Weight of 977,127 ha, Class EHI 5: Very Weight of 4,549.43 ha. Keywords: Erosion, Erosion Hazard Level, Water Catchment Area

Abstract

ABSTRACT This study aims to identify the types of Non-Timber Forest Products (NTFPs) in the KPHP Model Minas Tahura area and analyze the development opportunities to diversify the income of the people around the forest. The research method is survey method, with object of forest area and community around forest. The data taken are primary data, ie vegetation types that have the potential to generate NTFPs and respondent profile data as well as their interests and desires to develop NTFPs. While the secondary data in the form of general conditions KPHP Model Minas Tahura and other data that support. The results of all data are analyzed descriptively. Result of survey and analysis of vegetation found 30 species at the level of trees, While at the pile level found 21 species, the level of sapling 16 species, and the level of seeds as many as 29 species. From all levels of vegetation growth, there are 21 species that potentially produce NTFPs with various functions and benefits, such as food, medicines, and industrial raw materials. The results of interviews and answers to questionnaires from community respondents around the forest, all respondents know NTFPs and are eager to develop various types of NTFPs in forest areas. It can be concluded that KPHP Model Minas Tahura area has the potential to develop NTFPs based on the availability of critical land for rehabilitation with various types of plants and the desire of surrounding communities to get involved in such activities. Keywords : KPHP Model Minas Tahura; Mining opportunities; Non-Timber Forest Products (NTFPs); Potential
