The transportation sector is the second largest final energy consumer after the industry sector. The main energy issue in the transportation sector in Indonesia is the dominant use of oil fuels. Moreover, almost 60% of total oil fuels are being subsidized. On the contrary, the development and application of New and Renwable Energy (NRE) in the transportation sector has not been very successful. This paper applies the Analytical Hirarchy Process (AHP) in conjuction with optimization of the energy system using MARKAL model to select the best strategy for increasing the role of New and Renewable Energy (NRE) in the transportation sector. Three case studies are applied to evaluate the intervention by policy as an effort to increase the role of NRE in the transportation sector.

Biometana dari POME (palm oil mill effluent) merupakan energi terbarukan yang dapat dimanfaatkan sebagai substitusi gas alam dan LPG. Produksi biometana dapat mencapai 10% dari konsumsi gas bumi saat ini atau setara dengan 20% dari konsumsi LPG bila keseluruhan kapasitas produksi pabrik kelapa sawit dioptimalkan. Salah satu teknologi untuk produksi biometana yang sudah komersial untuk skala industri adalah water scrubber. Penerapan teknologi ini, khususnya di pabrik kelapa sawit Sei Pagar, Riau dengan kapasitas 250 Nm3/jam, belum ekonomis. Makalah ini bertujuan untuk melakukan kajian tekno ekonomi upgrading biogas berbasis POME dengan teknologi water scrubber. Berdasarkan hasil kajian yang dilakukan, biaya investasi upgrading biogas plant mencapai 53,2 miliar rupiah, sedangkan biaya operasi dan perawatannya mencapai 8,3 miliar rupiah. Harga biometana masih lebih mahal dari pada harga gas bumi sebesar 5,62 USD/MMBTU. Pada harga gas di atas 18,5 USD/MMBTU, upgrading biogas plant layak untuk dikembangkan. Kendala yang dihadapi dalam mencapai kelayakan adalah biaya investasi yang mahal serta harga gas bumi yang lebih murah. Berbagai kebijakan seperti transisi energi dan feed in tariff untuk energi terbarukan serta penerapan biaya eksternalitas dan depletion premium untuk energi fosil diharapkan dapat mendorong kelayakan penggunaan biometana berbasis POME di masa mendatang.

This study explores strategies for optimizing energy consumption in Indonesia's New Capital City (IKN) to achieve net zero emissions by 2045, focusing on energy efficiency, sustainable mobility, and renewable energy through the Low Emissions Analysis Platform (LEAP) model. Sustainable cars, such as renewable-energy-powered electric and green hydrogen-powered vehicles, can reduce energy consumption by 43% in 2045 and 33% in 2060, respectively, compared to BAU. GHG emissions per capita will drop 70% in 2045 and 63% in 2060. In NZE scenario, IKN can reach 100% green energy by 2045 with a 4.4 GW solar power plant, a 0.92 GWh BESS, and a full load hour capability of 4 hours. By 2045, 1.1 GW of hydropower and 143 MW of wind power are expected to be utilized. In 2060, hydropower will be 2.8 GW, wind power will be 184 MW, and solar power will be 8 GW with 1.6 GWh of BESS. Lack of legislation, technical expertise, high prices, inadequate grid infrastructure, and renewables shortfalls restrict Indonesia's BESS. Solar installation criteria, subsidies, and off-grid project incentives can all help ease BESS use. Forecasts predict 0.53 GW of rooftop solar PV capacity by 2045 and 3.35 GW by 2060. Net metering and solar tariffs boost rooftop solar system profitability. One ton of green hydrogen production requires 55.7 MWh from a solar power plant. Solar power plant capacity will rise to 0.49 GW by 2045, producing 19,359 tons of green hydrogen, and almost quintuple to 89,594 tons by 2060. Hydrogen generation, storage, transit, and distribution require specific infrastructure due to high capital costs and a lack of networks, yet interest in them is growing.
