Trade of reptiles in regional and international have been increased every year. The trade of reptileswas three divided, that is pet reptile, consumption reptile and reptile skin. The trade of skin reptile was greater than pests, because the skin of reticulated python is the most popular and to be excellent among exporters. Quotas export is all of number of quota exporter should be traded by exporter to international. This study aimed to identify of key variables exporter and formulation of calculation quota exporters of reticulated python. The methods used in this research were examination of administrative documents exporters and direct observation to the enclosure to 44 exporter skin of phyton reticulated. The key variables have corelate with the calculation of quota exporter are export realization ofthe previous year (X1), labor (X2), crusted product (X4), investment value (X5), yield (X6), PNBP (X7), state of export (X8), time of realization (X9), conservation activities (X10), chemicals (X11), and electricity (X12). Based on the analysis of linier regression formula obtained quota determination exporter: Y = 2.001 + 0.002 X3 + 0.072 X4 + 0.080 X5 + 0.030 X6 – 0.384 X9 + 0.059 X10. The result of regression equation of adjusted R square is 0.916. It means that the quation of regression linear is 91.6% for calculation of quotas as it could be explained by finished product, products crusted, yield, investment, time of realization and conservation activities, while 8.4% is explained by variables that are not included in of this research. Variables were positively related to the calculation of export quotas include finished product (X3), product crusted (X4), investments (X5), yield (X6), and conservation activities (X10), while the variables that have a negative relationship is time of realization ( X9).

The activity of exploration and production in oil and gas industry is significant greenhouse gas (GHG) emission source. PT. XYZ is one of upstream oil and gas industry in Indonesia and it have large crude oil and gas potential with it reserves that not manage yet. Therefore, GHG emission potential from the activity of exploration and production in PT. XYZ is very large. This study is done for estimate GHG emission reduction potential in PT. XYZ from various activities. Emission inventory is the first step to estimate GHG released to atmosphere. Method of estimation use the method developed by American Petroleum Institute (API). This study considers three types of mitigation measures options, including technical options (scenario 1), behavior option (scenario 2), and policy option (scenario 3). Based on emission inventory, flare and oil storage tank are primary source of GHG emissions in PT. XYZ. Scenario 1 prefers control of GHG emissions in flare and storage tank as primary emission source. While others scenario prefers to control GHG emission from transportation sector. Scenario 1 has potential to reduce emissions by 48.3 %. While scenario 2, and 3 in sequences have potential to reduce emissions by 0.15%, and 0.52%. Emissions flare and oil storage tank can be reduced through the installation of flaring gas recovery unit and vapor recovery unit. Both are effective and efficient in reducing GHG emissions in PT. XYZ. In addition, all mitigation measures of transportation sector provide benefits even though the amount of GHG that can be reduced is not significant.

Kawasan Hutan Dengan Tujuan Khusus (KHDTK) merupakan kawasan hutan yang ditetapkan oleh pemerintah untuk kepentingan umum seperti penelitian dan pengembangan, pendidikan dan latihan, dan religi dan budaya yang pengelolaannya diberikan kepada masyarakat hukum adat, lembaga pendidikan, lembaga penelitian, lembaga sosial dan keagamaan. Hutan Pendidikan dan Latihan Gunung Walat (HPGW) merupakan salah satu KHDTK yang ditunjuk dan ditetapkan oleh pemerintah dengan pengelolaan oleh Fakultas Kehutanan IPB. Penelitian ini bertujuan untuk mengidentifikasi permasalahan yang muncul dalam pengelolaan KHDTK serta merumuskan konsep solusi pengelolaan KHDTK oleh Perguruan Tinggi. Berdasarkan hasil identifikasi diketahui bahwa Fakultas Kehutanan IPB belum dapat melaksanakan kegiatan pengelolaan hutan yang terintegrasi terutama dalam pemanfaatan potensi hasil hutan yang ada di dalam kawasan. Hal tersebut dikarenakan diberlakukannya norma atau aturan umum perizinan usaha pemanfaatan atau pemungutan dan peredaran hasil hutan berbagai komoditas kehutanan yang berlaku umum bagi entitas usaha yang terkadang tidak relevan dengan tujuan pengelolaan HPGW. Peran pemerintah sangat dibutuhkan dalam upaya menyusun kebijakan pengelolaan KHDTK agar tujuan KHDTK dapat tercapai dengan kepastian pendanaan.

Publisher : President University

In recent years, concerns regarding to wastewater sludge disposal have increased globally. Production of sludge has increased recently due to the growth of population. Wastewater sludge classified as a hazardous substance, it is not easy to dispose because of certain treatment is required. Typically, sludge is treated at secured landfill which its limited in availability and expensive. On the other hand, wastewater sludge originated from biological treatment contains organic substance that can be converted into alternative energy resources. A technology is needed that is able to reduce the volume of sludge and convert sludge into energy source. We present an overview of various technologies that can be used for conversion of sludge into energy resources. Those technologies are anaerobic digestion, pelletization, combustion, pyrolysis and gasification. Progress and challenges of each technology is presented in detail. A summary of sludge characteristic originated from different source will be discussed as well. Emissions and residues that determines the environmental impact is also considered. Referring to some previous research, it known that wastewater sludge, as unwanted product, has the potential to become future energy resource. This potential can only be used properly if the method of conversion are effective and efficient.

Most of water we used as rinse water, for example water used for bathing, for washing hands, to wash clothes, and more, approximately 70-80% of water consumption will turn into gray water. Along with the increasing water demand, the raw water needs to be processed is increasing as well. However, the increasing need for raw water is not followed by an increase in raw water, both in quality and quantity. These conditions encourage efforts to find alternative sources of raw water which more secure than others in terms of quality and quantity. One of its efforts is by making use again (reuse) efluent from wastewater treatment. The technology will be used to process must be cheap, effective, and not difficult in treatment. Technology used in this study is constructed wetland. The purpose of this research is measuring the treatment efficiency, determining the optimum operating conditions, determining the criteria for water reuse. This research is conducted in the laboratory using a constructed wetland with type of plant is Typha latifolia. Variations are made in this study are detention time (1day, 3days amd 5 days) and type of reactors (constructed wetland & aerated constructed weland). Each reactor is given wastewater feed derived from effluent of WWTP Bojongsoang. Parameters examined in this study are COD, BOD, pH, and temperature. Measurement of COD, pH, and temperature conducted every day, while the BOD parameter are done after the reactor reaching steady state conditions. Based on the measurements, it is known that the best detention time to remove organic matter is at 5 days with efficiency between 91,2-94,9%. Aerated constructed wetland can remove organic matter better than non-aerated reactor, with good significance removal at 1 day detention time.

Industrial Estate development has an important role for national economic growth. The government regulation number 24 year 2009 (replaced by number 142 year 2015) states that most of all industrial / manufacturing activities in Indonesia should be located in industrial estate. By this reason, an integrated environmental management in industrial estate will become the significant strategic to support national sustainable development. Industrial estate developer should have a proper environmental management system to minimize the negative impacts of its activities to environment. The sustainability performance analysis was conducted in Jababeka Industrial Estate, year 2008-2014, which refer to PROPER KLHK green rating criterias (the assessment program for company performance rating in environmental management issued by Ministry of Environment and Forestry). The analysis was approached by multi-dimensional scaling (MDS) with rapfish software modification. The sustainability analysis result showed that the ‘sustainable’ status was only achieved on institutional management dimension (Stress: 23.15%, R2: 94.4), while other dimensions (ecology, technology, social and economy) had the status of ‘less sustainable’ or ‘not sustainable’. The dominant leverage factors in environmental management were 3R hazardous waste implementation (RMS 8.69 > median 4.35), the financing of water conservation and wastewater reduction (RMS 4.08 > median 2.275), community development implementation (RMS 6.38 > median 5.69), air emission reduction technology (RMS 10.65 > median 2.79), and benchmarking policies (RMS 15.45 > median 12.15). By considering this dominant leverage factors, Industrial Estate Company was recommended to apply the strategic plans to achieve the sustainable performance in the near future.

Penggunaan lahan di Kabupaten Bogor mengalami perubahan dari waktu ke waktu untuk pemenuhan kebutuhan pembangunan dan ekonomi masyarakat. Rencana Tata Ruang Wilayah Kabupaten (RTRWK) Bogor disusun sebagai pedoman merencanakan dan melaksanakan program pembangunan sehingga penggunaan lahan aktual dapat sesuai dengan rencana peruntukannya. Tujuan penelitian untuk mengetahui kesesuaian alokasi peruntukan ruang dalam pola ruang RTRWK dengan penggunaan lahan pada kawasan hutan di Kabupaten Bogor. Analisis perubahan penggunaan lahan dan kebijakan peruntukan ruang dilakukan dengan mengoverlaykan peta penggunaan lahan tahun 2008 dan 2016, peta pola ruang RTRWK Bogor tahun 2008 dan 2016, dan peta kawasan hutan Kabupaten Bogor. Hasil analisis menunjukan bahwa terjadi perubahan penggunaan lahan pertanian menjadi hutan (14.262 ha), lahan terbangun (257 ha), dan lahan terbuka (454 ha). Lahan hutan berubah menjadi pertanian (3.044 ha), lahan terbangun (8 ha) dan lahan terbuka (25 ha). Alokasi ruang dalam pola ruang RTRWK Bogor mengalami perubahan untuk hutan berkurang 7.410 ha, pertanian berkurang 457 ha dan lahan terbangun bertambah 8.219 ha. Pola ruang RTRWK 2016 yang sesuai dengan penggunaan lahan tahun 2016 di dalam kawasan hutan seluas 43.334 ha (55,20%). Tidak sesuai dalam implementasi di lapangan seluas 34.641 ha (44,13%), di mana kawasan hutan yang direncanakan sebagai pola ruang hutan seharusnya digunakan untuk penggunaan lahan hutan, yang terdiri dari kawasan hutan konservasi dan hutan lindung seluas 12.587 ha yang berfungsi pokok sebagai kawasan lindung disekitarnya namun penggunaan lahannya berupa pertanian, dan hutan produksi seluas 22.104 ha di mana dalam pengelolaan dapat dilakukan pemberdayaan masyarakat dengan sistem tumpangsari. Terdapat seluas 521 ha (0,66%) tidak sesuai dalam penentuan kebijakan peruntukan ruang, di mana kawasan hutan tidak dialokasikan sebagai rencana pola ruang hutan, sehingga akan menimbulkan ketidakpastian ruang dalam implementasi kebijakan selanjutnya

The quality of a healthy environment is supported by the environmental determinants, one of which is the environmental carrying capacity. The purpose of this study was to find out the picture of environmental quality of Pudu river which located at Mandau, Bengkalis district, Riau province. Method used are the comparison between supply and demand of the land and the comparison between supply and demand of the water. At the first method, the purpose is to determine the carring capacity based on the comparison between availability and demand of the land by calculate the demand of the land and land carrying capacity status. And for the second method comparison based on the consideration of the availability of the water and the water carrying capacity for the residents around Pudu river. Analytical results showed that the land carring capacity status of Mandau districts is surplus, it means the availability of the land (SL) is higher than the demand (DL). While the status of water availability at Mandau district is surplus and it means the value of water availability (SA) is higher than the demand (DA).
