The purpose of this research was to determine the distribution pattern, spatial character, and potential suitable habitat for andaliman growth with a suitability model approach in Samosir island, North Sumatera. Andaliman distribution pattern based on the calculation of the Standard Morisita Index (Ip) shows various patterns. There are three categories of distribution pattern, depends on the Standard Morisita Index The distribution patterns on each plot based on the calculation are: random (Location 1 – open area (Ip = 0.00)), uniform (Location 2 – plantation forest (Ip = -0.77); Location 3 – open field (Ip = -0.09)), and clump (Location 4 – plantation forest (Ip = 0.36)). Analysis of habitat suitability for andaliman used spatial modelling with the Principal Component Analysis (PCA) approach. This method utilized ecological variables, i.e.: Bare Soil Index (BSI), slope, Digital Elevation Model (DEM), rainfall, Normalized Difference Moisture Index (NDMI), and Normalized Difference Vegetation Index (NDVI). The result is 69.8% of Samosir Island is suitable for andaliman, while 26.4% of it is considered as highly suitable habitat.</em> Lasriama Siahaan Iwan Hilwan Yudi Setiawan Copyright (c) 2019 Jurnal Pengelolaan Sumberdaya Alam dan Lingkungan (Journal of Natural Resources and Environmental Management) 2019-12-02 2019-12-02 9 4 861 871 10.29244/jpsl.9.4.861-871 Metode Pengaturan Hasil Berdasarkan Jumlah Pohon dalam Pengelolaan Hutan Rakyat pada Tingkat Pemilik Lahan http://journal.ipb.ac.id/index.php/jpsl/article/view/24231 <em>Community forest management are individualized according the decision of the land owners and yet have a standardized manage-ment method.

The Reduced Emissions from Deforestation and Forest Degradation plus (REDD+) and Payment for Environmental Services (PES) scheme for the hutan desa is one of the alternative scheme to provide economic incentives for their effort to manage their forest sustainably. This study aims to evaluate the impact of the initiation of REDD+ and PES funds for hutan desa to deforestation and community wellbeing. The impact to deforestation is measured through quantitative approach by comparing quantitatively forest cover on 1070ha of village forest through satelite image analysis. The impact to community wellbeing is measured through participatory wellbeing assessment involving 30 informants during a focus group discussion. An attribution to the variables are conducted qualitatively by in-depth interviews to 25 key informants. The result shows eventhough the benefit provided by the initiation of REDD+ and PES (the money) is much less than the opportunity cost, the community is still accepting the scheme and succeeds reducing deforestation.

The separated nanoclays were then purified using centrifugation and membrane dialysis techniques. Potential of the extracted nanoclays as natural phosphate adsorbent was evaluated by characterizing their adsorption maxima (b values) according to the Langmuir isothermal adsorption model. It could be extracted 2.82 mg nc<sub>3</sub>/g tv<sub>3</sub> and 4.29 mg nc<sub>4</sub>/g tv<sub>4</sub>. The b values of nc<sub>3 </sub>at 12, 24, and 48 hours equilibration time (76.48, 92.10, and 117.54 mg P/g nc<sub>3</sub>) were higher than those of nc<sub>4 </sub>(50.17, 59.52, and 71.99 mg P/g nc<sub>4</sub>). The most effective equilibration-time was 48 hours. The extracted nanoclays were considered prospective as natural adsorbent for removal phosphate contaminant in waters</em> Untung Sudadi Rendy Anggriawan Syaiful Anwar Copyright (c) 2020 Jurnal Pengelolaan Sumberdaya Alam dan Lingkungan (Journal of Natural Resources and Environmental Management) 2020-01-01 2020-01-01 9 4 1032 1040 10.29244/jpsl.9.4.1032-1040 PENATAAN KAWASAN PASCA BENCANA TANAH LONGSOR DI PUNCAK PASS, KECAMATAN CIPANAS, KABUPATEN CIANJUR TANGGAL 28 MARET 2018 http://journal.ipb.ac.id/index.php/jpsl/article/view/21564 <p><em>Landslides often occur in Indonesia, including in Puncak which is a tourist area. A landslide disaster occurred at Puncak Pass, Cipanas Sub-district, Cianjur District, West Java on Wednesday, March 28, 2018 at around 08.00 PM. Typology of landslides that occur is a debris slide consisting of debris materials such as soil, rocks and large trees, and form a basin such as the shape of a horseshoe on the former landslide. Landslide occurred on the slope of the road and destroyed the hotel building, the park behind the hotel and pine forest. Many factors that influence the occurrence of landslide in Puncak Pass, from the analysis there are three main factors causing the landslide: the topography of the landslide is very steep, the occurrence of heavy rain for several consecutive days before the occurrence of landslides, and the slope which always disrupted the transport load of vehicles on it. Arrangement of landslide areas is very important to re-arrange the sustainable condition of the area against similar landslide disaster in the future. These arrangements are: handling of landslides during emergency response, determining the location of new road development, water and drainage management, cliff strengthening, land management, potentially affected settlements, and landslide disaster management.</em></p><p><em><br /> Keywords: Landslide, Puncak Pass, debris slide, sustainable safe area arrangement</em><strong><em></em></strong></p> Heru Sri Naryanto Firman Prawiradisastra Agus Kristijono Deliyanti Ganesha Copyright (c) 2019 Jurnal Pengelolaan Sumberdaya Alam dan Lingkungan (Journal of Natural Resources and Environmental Management) 2019-12-14 2019-12-14 9 4 1053 1065 10.29244/jpsl.9.4.1053-1065 IMPACT OF COAL MINING IN FOREST AREA TO CARBON EMISSION IN KUTAI KARTANEGARA, EAST KALIMANTAN http://journal.ipb.ac.id/index.php/jpsl/article/view/22811 Coal mining is an activity that contribute to greenhouse gas emissions, both from methane gas release of coal trap and the loss of lan cover plants. This study was conducted to estimate carbon emissions in coal mining areas inside forest areas by analyzing changes in landcover. The area of this study is Kutai Kartanegara Regency, East Kalimantan, where coal mining activities are quite massive. To obtain the extent of changes in land cover and the amount of carbon emissions in the area, analysis of Landsat 5 TM and Landsat 7 ETM+ imagery in 2010 and also the 2016 Landsat 8 OLI / TIRS imagery was used. The results showed that in the area of study there was a change in landcover of 12,663.28 Ha in the forest areas used for coal mining activities. Carbon emissions generated from this activity amounted to 0.60 Mton CO2-Eq Retna Kartikasari Arief Rachmansyah Amin Setyo Leksono Copyright (c) 2019 Jurnal Pengelolaan Sumberdaya Alam dan Lingkungan (Journal of Natural Resources and Environmental Management) 2019-12-14 2019-12-14 9 4 1066 1074 10.29244/jpsl.9.4.1066-1074
