The electric vehicles (EVs) market in ASEAN has seen rapid growth 2024, driven by the global trend towards sustainable transportation and strong government support. Thailand, with policies extensive charging infrastructure, emerged as a regional leader. Malaysia Indonesia are still early stages of adoption, grappling high vehicle costs, limited public acceptance challenges. A bibliometric analysis research output from 2015–2025 reveals an exponential EV-related studies, Malaysian...

Biogas is a new and renewable energy source that offers numerous advantages. It renewable, environmentally friendly, capable of reducing dependence on fossil fuels, economically valuable. Additionally, biogas has high-octane rating, making it suitable for use in high-compression engines. The as engine fuel requires adequate quality control, not all biogases can be used effectively fuel. Based previous research, the categorized into several clusters: Cluster one: contains high level methane,...

Today, in the industry 4.0 era, boundaries of scientific disciplines are blurred, everything seems to be interrelated and shows ability combined. Intelligent sensors combined with Artificial Intelligence (AI) have demonstrated their influence processes, design, maintenance manufacturing systems. Mechanical engineering tasked solving complex problems must able adapt this transformation, especially use digital IT combine principles physics mathematics materials science analyze, manufacture,...

Because of the significant demand for fuels in transportation sector Indonesia, as well concerns about energy security and global warming, renewable, sustainable, alternative sources such biofuels are required to replace petroleum-based fuels. Promoting production green diesel from crude palm oil (CPO) using fatty acid distillate (PFAD) its byproduct will make overall process more efficient environmentally friendly Indonesia. As a result, CPO-based be high-value sector. By replacing fossil...

In recent years, there have been many studies on the widespread use of liquid fuels derived from biomass. A common emphasis in such is fewer exhaust gas emissions and expansion renewable fuel production. Biodiesel considered to be an important type biomass that already produced commercially. But production biodiesel laborious comprises combination several chemical processes. This study examines effects using oil used with oxygen-rich chemicals combustion (in-cylinder pressure (Cp), heat...

The advantages of reusability, lower cost, and environmentally friendly operation have made the heterogeneous catalyzed methylic process a preferable alternative to homogeneously protocol. optimal production yield palm kernel shell oil (PKSO) methyl ester (PKSOME) was modeled using Response Surface Methodology (RSM). cost PKSOME determined, synthesized blended with diesel fuel various volume ratios. Several analyses were done, including thermophysical properties ASTM test methods, density...
