The process of natural gas production starting from drilling, processing, and distribution has the potential to release harmful substances into the environment. Therefore, it is necessary to analyze and identify the impact of natural gas production using the Life Cycle Assessment (LCA) method. In this study, the environmental impact of natural gas production was identi-fied using a gate-to-gate approach, using LCA and Microsoft Excel methods. The unit of func-tion used is 1 MMSCF (Million Million of Standard Cubic Feet). LCA methods include goal set-ting and scoping, Life Cycle Inventory (LCI), Life Cycle Impact Assessment (LCIA), and data interpretation. Environmental impacts are categorized using the CML-1A baseline, which includes Global Warming Potential, Acidification Potential, Eutrophication Potential, Photo-chemical Oxidation and Human Toxicity. LCA analysis shows that every 1 MMSCF of natural gas production will contribute to Global Warming Potential 4,067.72 kg CO2eq, Acidification Potential 2,07459 kg SO2eq, Eutrophication Potential 0.25365 kg PO4eq, Photochemical Oxi-dation 0.09891 kg C2H4 eq and Human Toxicity 2.41181 kg 1,4-DB eq. In the natural gas production process, the highest environmental impacts identified are from Gas Turbine Gen-erator (GTG) with Global Warming Potential of 1,986.78 kg CO2eq, Acidification Potential of 1.01686 kg SO2eq, Eutrophication Potential 0.11865 kg PO4 eq, Photochemical Oxidation 0.04813 kg C2H4 eq and Human Toxicity 1.13150 kg 1.4-DB eq. GTG converts energy from fuel combustion to generate electricity for production process equipment and office build-ings. High electricity consumption will further increase GTG gas fuel consumption which will contribute to increased Global Warming Potential, Acidification Potential, Eutrophication Potential, Photochemical Oxidation and potential human toxicity environmental impacts.

Lake Dendam is never a loticwaters with lots of human activities around the area. The high human activity around the waters has an impact on the quality of the waters and the organisms in the vicinity. This observation was carried out to obtain an up-to-date picture of water quality and micro-algae biodiversity in Revenge Lake for developing sustainable management strategies. Tests were carried out on the chemical and physical quality of the waters, and the biodiversity of microalgae which were then processed into an area management strategy. The results of the water quality test showed slightly polluted conditions with values of dissolved oxygen (DO), chemical oxygen demand (COD), total suspended solid (TSS), and phosphate which were still outside the water quality standards. However, conditions that can still be tolerated are peat waters. The microalgae biodiversity test showed the dominance and diversity of microalgae genera in the waters. The dominant genus is Nitzchia sp. From these results obtained six sustainable management strategies for Revenge Lake. Keywords : Biodiversity, Dendam Lake, microalgae, water quality

Penataan ruang yang baik mengurangi risiko bencana tanah longsor sesuai dengan tujuan penataan ruang sebagaimana tertuang dalam Undang-Undang Nomor 26 Tahun 2007 tentang Penataan Ruang yaitu untuk mewujudkan ruang wilayah nasional yang aman, nyaman, produktif dan berkelanjutan. Perwujudan ruang tersebut seharusnya tertuang dalam dokumen-dokumen rencana tata ruang yang terkait dengan keadaan risiko terhadap bencana. Peningkatan aktivitas pembangunan membutuhkan ruang yang semakin besar dan dapat berimplikasi pada perubahan fungsi lahan secara signifikan. Bencana tanah longsor dapat terjadi karena alih fungsi lahan menjadi lahan terbangun. Penelitian ini bertujuan untuk menganalisis nilai pengurangan risiko bencana tanah longsor akibat adanya rencana tata ruang wilayah. Penelitian bersifat kualitatif yaitu menganalisis rencana tata ruang dan kuantitatif yaitu analisis pemetaan risiko bencana. Hasil penelitian menunjukan bahwa Indeks bahaya/ ancaman bencana tanah longsor pada skenario eksisting berada pada kelas “bahaya sedang” karena mengalami pegurangan, namun pada skenario RTRW terjadi peningkatan pada kelas “bahaya tinggi” Meningkatknya luasan kelas bahaya longsor terjadi di enam dari delapan Kecamatan di Kota Lubuklinggau. Indeks Kerentanan bencana tanah longsor tidak mengalami perubahan yang signifikan antara skenario eksisting dengan skenario RTRW dimana semua skenario berada pada kelas kerentanan sedang. Indeks kapasitas bencana tanah longsor pada indeks kapasitas daerah berada pada level 2 yang berarti bahwa daerah telah melaksanakan beberapa tindakan pengurangan risiko bencana dengan pencapaian-pencapaian yang masih bersifat sporadis yang disebabkan belum adanya komitmen kelembagaan dan/atau kebijakan sistematis. RTRW Kota Lubuklinggau mengakibatkan kenaikan risiko bencana tanah longsor dengan Nilai Pengurangan Risiko (NPR) < 0 umumnya berada pada penggunaan lahan eksisting hutan alam atau pada kawasan rencana perkebunan. Luas area yang termasuk ke dalam NPR ini adalah sebesar 5.306,53 hektar atau 69,07 % dari luas Kota Lubuklinggau. Sedangkan Nilai Pengurangan Risiko (NPR) = 0 berarti wilayah tersebut tidak mengalami perubahan risiko akibat adanya RTR umumnya berada di penggunaan lahan eksisting sama dengan penggunaan lahan rencana (RTRW) misalnya kawasan Taman Nasional Kerinci Sebelat, hutan lindung Bukit Cogong, hutan produksi terbatas Hulu Tumpah, dan permukiman. Luas area yang termasuk ke dalam NPR ini adalah sebesar 11.334,93 hektar atau 30,93 % dari luas Kota Lubuklinggau. Berdasarkan hasil penelitian tersebut disarankan peningkatan kapasitas bencana melalui peningkatan kapasitas daerah dan kapasitas kesiapsiagaan bencana.

The low productivity of rice in Seluma Selatan District is caused by fertilization actions based on general recommendations and not based on site-specific recommendations. In fact, fertilization should be based on soil nutrient status, especially N, P and K. This study aims to determine the nutrient status and evaluate the suitability class of lowland rice in Seluma Selatan District, Seluma Regency. This study used survey methods, soil sampling, and laboratory analysis, then matched it with the soil fertility level classification system and land suitability classification. The results showed that the nutrient status of paddy fields in Seluma Selatan sub-district in low-medium rice fields was categorized. It is characterized by an acidic pH value and low P2O5 in providing nutrients for lowland rice plants. Evaluation of land suitability in Seluma Selatan sub-district shows that the land suitability classes are S2 and S3. The results of the evaluation of the most suitable land suitability for land unit 2 (Au.1.1.1) were quite suitable for S2n with available nutrient limiting factors at the P2O5 level and marginally suitable for S3n on land unit 4 (Hab.1.1.1) with available nutrient limiting factors at P2O5 and K2O levels. Efforts to improve the suitability class S2 (fairly suitable) can be increased to S1 class (very suitable) and the S3 land suitability class (marginally appropriate) can be increased to S2 (quite suitable) .

Cultivation of beef cattle in Indonesia is mostly carried out by smallholder farms. Therefore, the beef cattle assistance program from the government often involves farmer groups through a livestock raising system. This study aims to determine the impact of implementing various disturbance patterns applied by farmer groups on the development of beef cattle populations. The research was conducted from February to June 2021 in Padang Jaya District, North Bengkulu Regency. Data was collected through interviews with various informants, namely from the Agriculture Office of North Bengkulu Regency, Animal Husbandry Officers from Padang Jaya District, and Management of Farmer Groups. Reports on assistance for the livestock raising program in Padang Jaya District in the 2016-2020 period originating from the Agriculture Service became the basis for searching field information. Eight farmer groups from four recipient villages of the livestock raising program identified the patterns of disturbances and their impact on livestock population development. Secondary data related to this study were collected from BPS reports, Livestock and Animal Health Sector - North Bengkulu District Agriculture Service, and the Padang Jaya District Agricultural Extension Center. The data and information obtained are discussed descriptively. The results showed that there were four patterns of beef cattle raising applied by breeders, namely: (1) one calf deposit, (2) one calf deposit plus Rp. 300,000, (3) deposit of two children, and (4) patterns of rioting with a profit-sharing system. All of these rioting patterns increased the beef cattle population belonging to individual breeders, but only the rioting pattern with the deposit of two calves and a profit-sharing system was able to increase the population of ruminant livestock owned by farmer groups.
