Bioscrubber merupakan separator yang dapat digunakan untuk menurunkan konsentrasi hidrogen sulfida (H2S) pada biogas. Permasalahan yang mempengaruhi kinerja bioscrubber diantaranya yaitu jumlah oksigen berlebih (excess oxygen) dan suhu yang tidak sesuai dengan kebutuhan operasi sehingga menyebabkan tidak maksimalnya kinerja bioscrubber dalam menurunkan konsentrasi hidrogen sulfida (H2S). Untuk meminimalisir permasalahan ini maka dilakukan analisa data terkait kebutuhan jumlah oksigen berlebih dan suhu operasi yang optimal. Pada penelitian ini dilakukan pengumpulan data secara langsung yaitu dengan pengambilan data produksi biogas di Pembangkit Listrik Tenaga Biogas (PLTBg) Sei Mangkei yang kemudian dilakukan pengolahan data terkait kebutuhan excess oxygen dan suhu operasi pada proses separasi H2S. Dari penelitian yang dilakukan, diketahui bahwa proses penurunan konsentrasi H2S menggunakan bioscrubber yang ada di PLTBg Sei Mangkei membutuhkan excess oxygen sebanyak 363,4% dari kebutuhan oksigen teoritis dan suhu operasi 38oC untuk dapat menurunkan konsentrasi H2S hingga 97,5%.

This study aims to obtain an overview of the community empowerment model through cash-intensive work policies in village development. This study uses a descriptive method with a qualitative approach. The informants in this study were 12 people consisting of 4 Village Government members, 4 BPD members, and 4 community elements. In this study, the method used was a descriptive method or descriptive survey. The researcher used research procedures, namely: (1) orientation stage, (2) exploration stage, and (3) member check stage. The researcher used data processing and analysis techniques in a qualitative approach, namely: data review, data reduction, compilation of units and categories, checking the validity of data, and data interpretation. The results of the study indicate that: 1) Community empowerment in Banjar District Village, Banjar City is carried out by involving the community and village community institutions from development planning, development implementation and evaluation of development results; 2) Villages in Banjar District, Banjar City do not implement the cash-intensive work policy which is one of the priorities for the use of village funds in accordance with the provisions of laws and regulations, because the benefits and impacts are not as expected; 3) The objectives of village development through the cash-intensive work policy cannot be achieved.

PT. Pebana Adi Sarana targets monthly production operations of 20,000 tons/month while actual production is only around 15,000 tons/month, which means that the production target has not been achieved. The factors that cause the failure to achieve the production operation target can be due to ineffective equipment performance, Low equipment performance is one of the things that cause production not to be achieved, so it needs to be studied. The purpose of the study to be achieved is to analyze the actual productivity of loading and unloading equipment and transportation equipment after repairs and conduct improvement analysis using the Quality Control Circle (QCC) method. The data taken for the research is in the form of Excavator and dump truck cycle time data, effective working time, tool specifications. The actual productivity of loading and unloading equipment and transportation equipment at PT. Pebana Adi Sarana for dump trucks of 19,146 tons/month. trucks are 16,351 tons/month while for the Quality Control Circle (QCC) method. The company only needs to carry out the number of tools needed for 3 units of Scania p380 dump trucks and 1 unit of komatsu PC 300 excavator with a production of 21,295 tons/month has exceeded the production target set by the company.

Cost Recovery is a vital element in production sharing contracts (PSCs) within the oil and gas sector, allowing contractors to recover costs incurred during exploration and production through revenues generated from oil and gas production. This mechanism has a direct impact on the sustainability of operations and the management of natural resources, which in turn plays a critical role in supporting the national economy.This study aims to analyze the role and contribution of the cost recovery scheme in enhancing Indonesia's economic development, focusing on optimizing state revenue, increasing both foreign and domestic investment, and promoting the development of sustainable energy infrastructure. The method used in this study is a literature review, which includes data from journals and published articles.The main findings of the study show that the cost recovery scheme not only functions as an instrument to ensure the sustainability of upstream oil and gas operations but also has a significant impact on other economic aspects. In the context of national economic development, this scheme contributes to increasing state revenue through taxes and royalties, creating jobs, and supporting local economic development in oil and gas-producing regions. Moreover, cost recovery opens up opportunities for technology transfer and enhances human resource capacity in the energy sector.
