Electric vehicles (EVs) are a recognized solution for lowering greenhouse gas emissions and decreasing oil dependency, especially in Indonesia. Existing studies have explored the economic impact, challenges, and opportunities of EV adoption separately, lacking a holistic analysis. This study addresses this gap by providing a comprehensive assessment of the economic implications, challenges, and opportunities of EV adoption in Indonesia through a systematic literature review of 65 peer-reviewed articles, industry reports, and reputable publications from 2016 to 2024. The document analysis involved keyword-based literature selection, content analysis of economic metrics, and synthesis into key thematic areas. The findings reveal that EV sales in Indonesia have been rising annually, influenced by cost, driving range, environmental impact, technological features, charging infrastructure, battery, and government policies and incentives. EV adoption has positively impacted Indonesia’s GDP, attracted Foreign Direct Investment (FDI), created jobs, and reduced fuel consumption and imports. However, several challenges persist, including high EV costs, inadequate charging infrastructure, societal readiness, battery replacement costs and waste management, and limited model variety. Despite these challenges, opportunities exist in the form of market growth, FDI from nickel resources, energy security, job creation, and industrial expansion. Recommendations for creating a conducive EV ecosystem are provided for relevant stakeholders.

Electric vehicles (EVs) emerged as a help for Indonesia as a pathway to address environmental challenges related to air pollution and greenhouse gas emissions from the transportation sector. Despite governmental efforts, including Presidential Regulation No. 55/2019, EV adoption rates in Indonesia remain low, although sales are increasing annually due to limited charging infrastructure, high upfront costs, and consumer perception. This study distinguishes itself from previous research by moving beyond a singular focus on policy, adoption factors, barriers, or economic opportunities. Instead, it integrates these dimensions into a cohesive analysis while placing particular emphasis on government policies. By adopting this multidimensional approach, the study presents a nuanced understanding of EV adoption in Indonesia, exploring not only the drivers, challenges, and economic potential but also the tangible benefits of EV manufacturing and usage for both producers and consumers within the current regulatory framework. It highlights the transformative impacts of EV adoption on key areas such as job creation, GDP expansion, and energy security, offering strategic insights for policymakers, industry leaders, and stakeholders. Future research could explore rural infrastructure development, local battery production impacts, and long-term economic implications of EV in Indonesia’s ecosystem.

Coal contributed 303 million tons of CO2 (49% of total emissions) in Indonesia in 2021. The Indonesian government plans to retire all coal-fired power plants (CFPPs) to achieve net-zero emissions by 2060. Nuclear power plants (NPPs) have low CO2 emissions. This research aims to analyze the status of the nuclear program and examine the opportunities and challenges of NPPs in supporting net-zero emissions. The method used is a literature study of national positions and a simulation of the use of NPPs with the low emissions analysis platform (LEAP) up to 2060. The Business as Usual (BaU) scenario still relies on CFPPs. The retired CFPP scenario consists of NPP utilization of 0%, 5%, 10%, and 15%. It was found that the national position of Indonesia is in phase 1 (considering), because legally there is no policy on the use of NPPs in laws, the National Development Plan, or energy policies. A Nuclear Energy Program Implementation Organization (NEPIO) has not yet been established. The simulation results conclude that with limited renewable energy potential, NPPs have the opportunity to fulfill electricity production needs and reduce CO2 emissions significantly. The challenge of using NPPs is the increasing production and investment costs of electricity that come along with the increase in the use of NPPs.

Nowadays, increased interest among the scientific community to explore the Calophyllum inophyllum as alternative fuels for diesel engines is observed. This research is about using mixed Calophyllum inophyllum-palm oil biodiesel production and evaluation that biodiesel in a diesel engine. The Calophyllum inophyllum–palm oil methyl ester (CPME) is processed using the following procedure: (1) the crude Calophyllum inophyllum and palm oils are mixed at the same ratio of 50:50 volume %, (2) degumming, (3) acid-catalysed esterification, (4) purification, and (5) alkaline-catalysed transesterification. The results are indeed encouraging and satisfy ASTM D6751. CPME shows the high heating value (37.9 MJ/kg) but low kinematic viscosity (4.50 mm2/s) due to change a higher proportion of shorter-chain and unsaturated FAMEs, which tend to lower viscosity compared to Calophyllum inophyllum methyl ester (CIME).). The blended fuels exhibit higher brake-specific fuel consumption (BSFC) and NOx emissions, along with lower brake thermal efficiency (BTE) and reduced CO and HC emissions compared to diesel fuel across the entire range of speeds. Among the blends, CPME5 offered better performance compared to other blends fuel ratios.

Biodiesels have gained much popularity because they are cleaner alternative fuels and they can be used directly in diesel engines without modifications. In this paper, a brief review of the key studies pertaining to the engine performance and exhaust emission characteristics of diesel engines fueled with biodiesel blends, exhaust aftertreatment systems, and low-temperature combustion technology is presented. In general, most biodiesel blends result in a significant decrease in carbon monoxide and total unburned hydrocarbon emissions. There is also a decrease in carbon monoxide, nitrogen oxide, and total unburned hydrocarbon emissions while the engine performance increases for diesel engines fueled with biodiesels blended with nano-additives. The development of automotive technologies, such as exhaust gas recirculation systems and low-temperature combustion technology, also improves the thermal efficiency of diesel engines and reduces nitrogen oxide and particulate matter emissions.

Eastern side of Indonesia has a group of scattered Islands and have a great distance from the main Island. Fossil fuels are the main option for meeting the needs of electrical energy in the outer Islands. But the availability of fossil fuels is very dependent on the weather and modes of transportation. In addition, fossil energy also causes emissions and environmental pollution, so efforts to diversify alternative energy by utilizing renewable energy are needed to meet energy needs. Ut Island, Maluku is one of the Islands which is not yet powered by utilities. In this paper, the HOMER software is used to determine the optimal hybrid power plant configuration from a techno-economic perspective by utilizing energy resources available on the Island. From the simulations that have been carried out wind speed has a significant influence on the optimal configuration of the PLH system. Load value affects the amount of NPC and COE. The greater the load is fulfilled, the higher the NPC. But contrary to NPC, COE value will decrease.

In this paper, an energy monitoring system for small scale wind turbine is proposed. The monitoring system process includes measuring wind turbine power output (voltage and current) and storing systems. The measurement results will be stored in a micro SD at the real time. All processes for measuring and storing data in a data logger were carried out by a microcontroller through several sensors and storage media. The data logger were designed and implemented as small as possible to save material and enhance the performance of serial communication between components inside. Hence, most of components are installed by Surface Mounting Device (SMD) packaging resulted a compact data logger size as 7cm x 8cm. Furthermore, by using FAT32 system files, the data logger is able to operate a micro SD with a size of up to 32GB. Finally, this data logger shows a good capability for measuring voltage, current and storing the results into the SD card including the measurement period.

Compact permanent magnet synchronous generators (PMSGs) for renewable energy conversion are required for remote areas. In this work, an 18-slot, 8-pole PMSG (18S8P PMSG) was designed and fabricated for small-scale wind turbine energy conversion. Finite element analysis was conducted to assess the magnetic flux density distribution of the 18S8P PMSG prototype. The simulation results showed that most of the magnetic flux values were within 0.4–1.5 T, which was well below the saturation level for 35JN360 material. The magnetic flux intensities of the stator and rotor cores were within the optimal magnetic permeability range of the 35JN360 material. There were seven steps involved in fabricating the 18S8P PMSG prototype: (1) material cutting, (2) burring, (3) stacking, (4) welding, (5) coil winding, (6) configuration wiring, and (7) assembling. The electromagnetic performance results showed that the back electromotive force voltage of the 18S8P PMSG prototype seemed to be proportional to the rotor speed, where K E was 0.52 V·s/rad. The no load torque maximum of 18S8P PMSG is 1.7 N.m at 5000 rpm. The mechanical performance results showed that the highest power output (2500 W) was obtained for the 18S8P PMSG prototype at a rotor speed of 5000 rpm using the 20-Ω load model. The maximum efficiency of this prototype was 85.4%.
