      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

  • PENDUGAAN POTENSI TEGAKAN EKALIPTUS (Eucalyptus Pellita F. Meull)
           MENGGUNAKAN METODE TREE SAMPLING DAN CIRCULAR PLOT

    • Authors: Muhammad Ikhwan, Emy Sadjati, Enny Insusanty
      Abstract: ABSTRACT The forest inventory is basically a data collection activities. This activity is relatively important, because the effect on further activities. Hence the data collected must have a high enough accuracy. A way of determining the sampling unit is considered to be simpler, easier, and faster is the tree sampling method.  The purpose of this study was to quantify the potential large stands of eucalyptus in the Forest of eucalyptus plants in the Faculty of Forestry and calculate the relative efficiency of sample unit.  The total area is 0.11 ha of eucalyptus stands. Unit examples used are circular, 4-trees sampling, sampling 5-trees, and 6-trees sampling is done by simple random sampling method.  Potential stands of eucalyptus with method 6 sample trees have an average volume stands perplot is 0.07 m3, with the volume of the stand for the entire area is 84.71 m3 with a sampling error of 36,96%. Potential stands of eucalyptus trees by the method of example 8 trees have a volume average stocking each plot is 0.04 m3, with the volume of the stand for the entire area is 43.22 m3 with a sampling error of 51.47%. Potential stands of eucalyptus by using 10 sample trees have an average volume stands each plot was 0.03 m3, with the volume of the stand for the entire area is 39.74 m3 with a sampling error of 53.34%. Potential stands of eucalyptus with a diameter circular sample plots of 12 m has an average volume stands each plot is 7.88 m3, with the volume of the stand for the entire area is 76.72 m3 with a sampling error of 14.43%

      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

    • Authors: Muhammad Reza Lesmana, Ambar Tri Ratnaningsih, Eni Suhesti
      Abstract: ABSTRACT          The pulp and paper industry produces liquid waste in its production process. Liquid waste in solid form of sludge can be utilized as compost fertilizer. Research conducted at PT. Indah Kiat Pulp and PT Arara Abadi Rasau Kuning District, Riau Province. The aim of this research is to know the effect of compost fertilizer from pulp and paper industry waste on Eucalyptus pellita growth and to determine the most appropriate dose of compost for growth of Eucalyptus pellita. The research method was done by applying compost in 3-month Eucalyptus pellita with dosage of o gram, 750 gram, 1000 gram and 1250 gram. Parameters measured over 3 months were plant height, plant diameter and number of leaves. Provision of compost fertilizer from pulp and paper industry waste has no significant effect on Eucalyptus pellita growth. Visually, the most appropriate dose of compost for the growth of Eucalyptus pellita is a dose of 1000 grams. Keywords: compost fertilizer; Eucalyptus pellita; , fertilizer dose; sludge
