Indonesia was once one of the main players in incandescent lamp markets. However, Indonesian lighting manufacturers cannot compete with cheaper imported compacted fluorescent (CFL) and light-emitting diode (LED) lamps; consequently, their market share has significantly reduced. Furthermore, the absence of compulsory standard has led to an abundance of low-quality and low-cost lamps coming from foreign manufacturers. This study aims to propose policies to improve the market share of domestic lighting manufacturers. Data were collected through a survey and series of interviews and focus groups discussions. A causal loop diagram was then drawn based on insights from the primary data to propose systematically arranged policies. The results suggested five recommendations: disseminating local lamp brands through compulsory use in government institutions and state-owned enterprises, implementing MEPS, securing commitments from construction planners and contractors to use local lamps, mandating enforced permit for imported LED lamps, and investing in the LED chip industry. These policy recommendations are expected to increase the market share of local lighting manufacturers. @en

Several developing countries have attempted to reduce liquefied petroleum gas (LPG) imports and subsidies by shifting from the use of LPG to electric stoves. In Indonesia, the LPG subsidy reached US$ 4.9 billion and LPG imports increased to 6.3 million tonnes in 2021. Our study aims to analyse the feasibility of an induction cooker program in Indonesia to reduce LPG subsidies. Firstly, we calculated the energy equivalent factor of the induction cooker compared to the LPG cooker. Subsequently, we surveyed 1006 respondents with different electricity connection capacities regarding their monthly LPG consumption and perceptions of induction cookers. We found monthly electricity consumption for the induction cooker to be around 62 kWh to 235 kWh, depending on the customer group. Cooking with the induction cooker has a lower energy cost compared to cooking with the unsubsidised 12 kg LPG cylinder. However, for customers previously using the subsidised 3 kg LPG cylinder, the induction cooker program only reduces energy costs for cooking for the 450 VA customers. The LPG subsidy saving can compensate for the capital costs of switching to induction cooking within three years. Several policy recommendations are discussed based on these findings.@en

Assessing the progress of lectures ensures the involvement of lectures in the exercise of science dissemination by research, education, and community service. That job affects the performance of lecturers at universities throughout the country. The performance of lecturers is evaluated regularly because of the vast number of evaluation attributes. Manual assessment can take time and cannot be carried out. In the evaluation of lecturer's outcomes, a decision support model is needed to facilitate decision making. This study applies the preference ranking organization method for enrichment assessment (PROMETHEE) as a decision model in Multi-Criteria Decision Making (MCDM) and Geometric Analysis for Interactive Aid (GAIA) as a geometric analysis in determining lecturer performance. This analysis resulted in the maximal value of an alternative of 2 with Phi 0.2333, followed by 1 and 3 alternatives. These results suggest that alternative 2 is the best way to assess the performance of lecturers as the main indicator. Alternative 3 is the least recommendable alternative because of its lowest precision on the basis of visualization results. @en

Energy demand growth in Asian countries is predicted to be the highest in the world. One of the drivers of energy demand growth is urbanization. Along with growing urban areas, public infrastructure, such as streetlights, is also expanding. Unfortunately, energy conservation measures in public facilities are commonly constrained by the budget limitations of local governments, while the potential participation of energy service companies (ESCO) requires regulation reformation settling the contradicting regulations. This study proposes several policy recommendations to modify existing guidelines for selecting ESCOs for the energy efficiency of streetlights in Indonesia that has the highest urbanization rate. Regulation review and several potential improvements for selecting ESCOs are provided. In 2017, the Ministry of Domestic Affairs released a Circular Letter to solve barriers to ESCO businesses in public sectors; however, the Circular Letter could be improved in several ways by eliminating the clauses on the holder of intellectual property rights, revising the valuation of economic benefit bidding, and increasing the maximum contract period. Moreover, we propose the use of smart street lighting technologies to improve the value-added services of streetlights and the establishment of a super ESCO to accelerate ESCO business activity in all economic sectors.@en
