Salah satu renewable energy yang memiliki potensi besar di Indonesia adalah energi air. Indonesia memiliki kapasitas tenaga air sebesar 76000 MW. Teknologi mikrohidro dan minihidro merupakan teknologi yang tepat untuk dikembangkan di wilayah terpencil di Indonesia. Penelitian ini bertujuan untuk menganalisa perkembangan teknologi PLTMH di Indonesia serta melihat strategi pengembangan yang tepat untuk PLTMH di Indonesia. Penelitian ini merupakan penelitian kualitatif yang menggunakan metode studi literatur dan analisis SWOT. Hasilnya menunjukkan bahwa dalam periode 2014 hingga 2021, teknologi PLTMH di Indonesia mengalami perkembangan yang signifikan, terutama di luar Pulau Jawa sehingga meningkatkan rasio elektrifikasi di Indonesia. Hal ini berkaitan dengan keunggulan mikrohidro yang dapat meraih wilayah-wilayah terpencil. Hasil analisis SWOT menunjukkan bahwa strategi pengembangan PLTMH sebaiknya berfokus pada aspek strengths dan opportunities saat ini. Dan diharapkan teknologi PLTMH saat ini lebih terarah pada pengembangan hybrid renewable energy sources (HRES).
This study aims to find alternative energy in substitution high speed diesel (HSD) in the railway by measuring the economic, supply chain, and liquefied natural gas (LNG) optimization especially in Java. The economic analysis using the feasibility of investment method in LNG locomotive, supply chain analysis to simulate infrastructure of transportation and distribution LNG to identify internal and external factors affecting. The economic analysis result showed fuel saving costs up to 36%, the NPV is positive, and the IRR higher than the discount rate so the investment is feasible to held that will bring benefits for country’s revenues from using dual fuel in LNG locomotive. Supply chain analysis provide two simulation models of LNG distribution for railway that suitable to be applied in Java Island, the source of LNG coming from outside Java Island using existing LNG plant and the source of LNG coming from inside Java Island using mini LNG plant.
Dalam bidang perekonomian Islam, di antaranya lembaga perbankkan ataulembaga non bank telah banyak mengalami perubahan dari zaman ke zaman,baik dalam hukum atau dalam praktik pengembangannya. Landasan darididirikannya asuransi Syari’ah adalah landasan filosofis atau teologis,karena asuransi Syari’ah merupakan salah satu solusi bagi pihak-pihak yangmengatasi musibah atau bencana yang bisa terjadi sewaktu-waktu. AsuransiSyari’ah atau takaful adalah saling memikul risiko di antara sesama orangsehingga antara satu dengan lainnya menjadi penanggung atas risiko yanglainnya. Saling pikul risiko itu dilakukan atas dasar saling tolong-menolongdalam kebaikan dengan cara masing-masing mengeluarkan dana ibadah(tabarru) yang ditunjukkan untuk menanggung risiko tersebut.
Natural gas is the primary commodity of Indonesia’s energy supply and an important policy issue. Domestic gas demand is dominated by the industrial, power sector, and fertilizer. Over the past five years, Indonesia’s natural gas prices have increased significantly, which will undoubtedly affect the consumers. We summarized and analyzed policy, literature, and interviews with stakeholders to find the main factors of gas prices. This study concluded that the government has a more dominant role in determining gas prices. The increase in gas prices was mainly influenced by the upstream project’s economics, the tariff for transmission, and managing natural gas infrastructure. The application of indexation with ICP and the escalation price also contributed to the high price. The Government needs to consider gas price adjustments carefully because these commodities have a multiplier effect and affect industry competitiveness.
