Abstract

Gasification stoves that utilize used cooking oil as fuel represent a significant innovation in renewable energy. People generally perceive used cooking oil as cooking oil that is no longer suitable for frying, often discarding it as waste or selling it to collectors for export and biodiesel production. However, used cooking oil can be repurposed as stove fuel, presenting an advancement in appropriate waste-to-energy technology. This approach enables cooking oil that is no longer used for frying to serve as a renewable fuel source for stoves. This study aims to analyze the efficiency of used cooking oil stoves by employing a gasification mechanism to accelerate heating. The efficiency evaluation includes thermal efficiency, measured using the Water Boiling Test method, along with values for Fuel Consumption Rate (FCR), Combustion Input Power (Pin), and Combustion Output Power (Pout). Thus, our study is the first to comprehensively evaluate the performance of used cooking oil (UCO)-fueled gasification stoves by analyzing these metrics, addressing a research gap in prior studies. Testing and analysis were conducted using water samples of three different volumes: 1 liter, 2 liters, and 3 liters. The results indicate thermal efficiency rates of 30.49 % for 1 liter of water, 15.54 % for 2 liters, and 16.45 % for 3 liters. The highest recorded FCR value is 1 liter/hour, the largest Pin value is 8,246.10 watts, and the highest Pout value is 1,481.28 watts. The decline in thermal efficiency and output power is attributed to the stove’s design. Specifically, the blower pipe air hole is positioned perpendicular to the blower pipe within the combustion chamber. As a result, the flames primarily strike the combustion chamber walls, with only a portion of the reflected heat directed toward the container holding boiling water. This leads to excessive heating within the combustion chamber, while the temperature of the flames reaching the water container remains relatively lower. The electrical power consumption of the stove is measured at 10.89 watts. As a contribution, our study provides an alternative cooking solution that supports Indonesia’s energy diversification efforts by reducing reliance on LPG and alleviating the government’s subsidy burden.

Abstract

Clean cooking is a critical agenda for enhancing access to clean energy in developing nations. In 2023–2024, the Indonesian government implemented a programme to distribute free rice cookers to underprivileged communities, yet this initiative has not previously been evaluated. This study addresses that gap by examining the impact of the rice cooker distribution on household energy consumption and LPG dependency. While several studies have assessed clean cooking programmes—such as biogas, induction, solar-powered stoves, and electric pressure cookers—this research is among the first to evaluate a rice cooker programme in a large-scale field setting, thereby offering novel insights and contributing to the literature on the clean energy transition. A Slovin sampling strategy selected 600 respondents from among 342,621 households across 36 provinces with a margin of error of approximately 4.1%. Primary data were analysed using descriptive statistics, including frequency distributions and cross-tabulations, alongside inferential methods such as ordered logistic regression to investigate the determinants of satisfaction of this program and also t-tests to compare electricity consumption and LPG usage before and after receiving the rice cooker. In addition, secondary data comprising 5,814,476 records on monthly electricity consumption from January 2023 to May 2024 were utilised. Our evaluation reveals that the free rice cooker programme has led to a significant increase in per capita electricity consumption and a corresponding reduction in LPG consumption and subsidies. Although household electricity bills have risen, most respondents report that the efficiency and convenience of the rice cooker offset these additional costs. These findings support the further expansion and continual evaluation of such clean cooking initiatives, enhancing energy resilience in Indonesia and other developing countries.

Abstract

This study assesses the five-year operational performance of a 120 kWp grid-connected rooftop photovoltaic (PV) power plant with multiple locations in Blora, Central Java, Indonesia.  By analyzing real-world energy yield, degradation rates, and climate-related impacts, the study identifies key environmental and technical factors influencing PV efficiency.  Performance data from 2020 to 2025 show varying degrees of degradation across sites, with Widya Patra 3 showing the greatest reduction (51.09%), and Widya Patra 2 showing the least (12.5%).  The study confirms that dust accumulation, shading, temperature fluctuations, and humidity have a significant impact on long-term efficiency.  Climate variables such as sunshine duration, rainfall intensity, and wind speed were found to have a direct relationship with energy yield.  These findings highlight the importance of regular maintenance, proactive cleaning strategies, and optimized PV system designs for better performance and sustainability in tropical climates.  The study sheds light on future PV reliability improvements, guiding the implementation of climate-resilient strategies in solar energy development.

Abstract

Despite growing interest in the European Union’s Carbon Border Adjustment Mechanism (CBAM), there remains a significant research gap in reviewing its nuanced impacts on the least developed economies—particularly in terms of sectoral vulnerabilities, institutional constraints, and the absence of empirical evidence from real-world implementation. Thus, we systematically investigate the CBAM implications for developing countries through a structured literature review. We offer a novel contribution by examining CBAM’s overlooked impacts on the smallest and least developed economies, highlighting distributional effects on labor-intensive sectors and small exporters. Starting with an initial pool of 1,197 articles sourced via Publish or Perish, we apply the PRISMA and PICO frameworks to screen and refine the selection, ultimately analyzing 37 peer-reviewed articles published between 2015 and 2024 in Q1–Q3 Scopus-indexed journals. Our review identifies five major thematic concerns: trade competitiveness, industrial vulnerability, green technology access, climate justice, and policy responses. It finds that CBAM poses significant economic risks for carbon-intensive exports from the Global South, particularly in sectors such as iron, fertilizer, cement, and aluminum. Countries like Indonesia, India, China, and Vietnam face varying degrees of exposure depending on emission intensity and trade composition. We highlight the absence of embedded climate justice mechanisms and structural barriers to green technology access, which may hinder just net-zero transitions. In response, scholars recommend policy mechanisms such as revenue redistribution, differentiated carbon accounting, and international capacity-building. We conclude by contrasting CBAM with protectionist measures such as those enacted during the Trump administration, emphasizing CBAM’s environmental rationale while calling for adaptive, equitable strategies that align global climate goals with sustainable development in vulnerable economies. Our study advances academic discourse by elucidating the varied ways in which CBAM is conceptualized and debated across different scholarly perspectives. It also offers practical recommendations for policymakers—including financial assistance, technology transfer, and institutional capacity building—to better align climate ambition with the principles of development equity.

Abstract

Carbon pricing serves as an effective economic instrument to mitigate greenhouse gas emissions while fostering investment in renewable energy by reducing dependence on fossil fuels. This study examines the development of carbon pricing policies to accelerate the energy transition, focusing on the Industrial Processes and Product Use (IPPU) sector. The proposed scheme is based on the Emissions Trading Scheme (ETS), tailored to local regulations and industrial capacities. This research employs a systematic review and content analysis of successfully implemented carbon pricing policies in various countries. While carbon pricing has been applied in the energy and forestry sectors, existing studies often lack specificity regarding emission thresholds or quantified carbon values across different emission sources. The IPPU sector, despite being a significant emitter, remains underrepresented in current policy design and academic literature. The findings indicate that carbon commercialisation supports renewable energy transition projects and increases investment in the electricity sector. This study proposes a carbon credit scheme tailored to the Indonesian wood industry (referred to as Industry X), which has begun integrating biomass and bioenergy to compensate for fossil-based emissions. The novelty of this study lies in its targeted focus on the IPPU sector and the practical application of a carbon pricing framework for industrial decarbonisation. The results suggest that integrating carbon pricing with fiscal incentives and energy regulations enhances industrial competitiveness in transitioning to clean energy. This study provides policy recommendations to improve carbon pricing mechanisms, supporting renewable energy investment and sustainable industrial transformation.
