the demand for electricity supply is projected to continue rising. In Indonesia, PLN (Perusahaan Listrik Negara) is the main electricity provider, but it often faces challenges in meeting this demand, especially with frequent power outages that disrupt industrial and societal activities. To address this issue, many companies have turned to using generator sets (gensets) as an alternative solution to ensure a stable energy supply. Although the use of gensets provides energy independence, it requires a significant investment. Therefore, an in-depth analysis of the efficiency and economic feasibility of using gensets is necessary. This study aims to analyze the use of gensets at PT. Teladan Prima Agro Bukit Permata Mill, located in Kaubun, East Kutai, focusing on technical-economic aspects such as Present Value (PV), Future Value (FV), Net Present Value (NPV), Internal Rate of Return (IRR), and Break Even Point (BEP). Data collected directly from the field includes genset specifications, electricity load, energy consumption, fuel usage, and genset operations. The analysis results indicate that the 455 KVA genset is capable of meeting the factory's electricity needs with an initial cost of IDR 649,649,996. The NPV calculation shows a value of IDR 880,380,813, with an IRR of 6.63%. The BEP is achieved in the 12th month with a profit of IDR 109,645,114. Based on these results, the operation of the genset at PT. Teladan Prima Agro Bukit Permata Mill is considered feasible and profitable in the long term.

forms community financial institutions, are efforts to create activities that make this possible. Increasing the creativity and productivity of the people of Babakan Village who face several obstacles in strengthening the fish cultivation population, including the dry season causing drought, this has an impact on the development of fish cultivation, the outreach and training by the Babakan Village Government for fish cultivation groups regarding their potential, the cultivator community has not been maximized. Fish lack insight and knowledge so that fish farming management is carried out by autodidacts. The conclusions obtained show that the role of the village government in strengthening the "Mina Kariya" fisheries cultivation group in Babakan Village, Pangandaran District, Pangandaran Province is basically functioning and very good. However, it still faces several obstacles, such as the lack of consensus among all breeders and it is still not optimal. So far we have not found an alternative to making our own food, so fish food still needs to be purchased. Farmers' skills and knowledge are still low and there are no alternative aquaculture techniques that can help farmers run their operations effectively. There is no research that focuses on the role of the Village Head in empowering community business groups, especially in Pangandaran Regency, so it is urgent in this research to find solutions to solve the problems that occur.

Abstract:Islamic economics has different principles from conventional economics, including in terms of sales contracts. In Islamic economics, there are several types of sales contracts used, such as bai' al-salam (future sales) and…
nd bai’ al-salam(manufacturing sales). Trust sales contracts are also important in ensuring transparency of the price of the goods or services sold. The research method uses descriptive qualitative in describing and explaining specifically with literature studies in data collection. The purpose of this research is to find out specifically about the types and qualifications of sharia sales that do not contain gharar and usury. In Islamic economics, payments in sales contracts can be deferred or paid in installments without involving interest or riba. This allows the buyer to pay according to an agreed schedule. Sales contracts in the Islamic economy differ from interest-bearing loan contracts, where there is an exchange of goods or services at a predetermined price. Islamic banks use sales contracts as a legitimate alternative to interest-bearing loan contracts, allowing them to provide financing that is fair and compliant with sharia principles. In the Islamic economy, there are also contracts for the sale of future commodities (salam), the sale of manufacturing (istisna'), and currency exchange (sarf). Islamic banks have an important role to play in facilitating these sales contracts, as intermediaries who ensure the contracts adhere to Shariah principles and meet applicable legal requirements. With a good understanding of the different types of these sales contracts, economic actors can choose the ones that suit their needs while complying with sharia principles.
