| Benchmarking Energy Demand in Medium-Scale Palm Oil Mills: A Comparative Analysis of Electrical and Thermal Intensities Toward Renewable Energy Substitution | ||||||
Energy use in palm oil mills remains a critical determinant of both production costs and environmental sustainability. This study analyzed the energy consumption patterns and residue utilization potential in an 8 t/h palm oil mill, aiming to achieve energy self-sufficiency through the effective use of mill residues. The total energy demand was 163.8 kWh/h, equivalent to 20.5 kWh/t FFB, which aligns closely with the electrical energy benchmarks of 18–22 kWh/t FFB reported in recent audits. Kernel cracking, drying, and clarification were the most energy-intensive processes studied........

| Designing Youth Housing Through Configurational Theories: Space Efficiency and Community Integration for Young People | ||||||
Youth housing is an increasingly relevant socio-spatial issue, which was triggered by economic insecurities, change of life stages, and changing household structures. The rise of housing prices and the intensified residential mobility has led to the spread of co-housing and co-living conditions hence creating sensitive questions relating to spatial efficiency and incorporation of community life. This paper explores the role of configurational design in relieving such problems in the area of youth housing.........

| Prediction of Decadal Trend in Black Carbon Over Indo-Gangetic Plain | ||||||
The Indo-Gangetic Plain (IGP), one of the most densely populated and industrially active regions in South Asia, experiences substantial atmospheric loading of black carbon (BC), a critical short-lived climate pollutant influencing air quality, monsoon dynamics, and radiative forcing. This study aims to investigate the long-term temporal dynamics, seasonal variability, and statistical behaviour of BC concentrations over the IGP using MERRA-2 reanalysis data from 2001 to 2024. The uniqueness of this work lies in its comprehensive integration of linear and nonlinear trend analyses with temporal dependence diagnostics to enhance the robustness of interpretation.........

| From Abundance to Energy Waste: Context Architecture and Regulatory Instruments for Mitigating Curtailment in the Brazilian Energy Transition | ||||||
The accelerated expansion of renewable energy sources in the Brazilian electric power system has increased the supply of clean energy while simultaneously exposing operational, regulatory, and institutional constraints related to the absorption of this generation. In this context, curtailment has become a central issue in the debate on system efficiency and the rational indication of energy use, as it reveals situations of waste associated with transmission constraints, lack of flexibility, and misalignments between generation and demand. The analysis of this phenomenon therefore requires an integrated perspective that considers not only technical aspects but also regulatory and economic arrangements embedded in the energy transition process.........

| Numerical Analysis of Alternative Power Output of Spark Plugs on Engine Performance and Emission Using Ricardo Wave | ||||||
Emission released from the internal combustion engines run on fossil fuels which contain hydrocarbon (HC). Normal combustion products of any IC engines are Carbon dioxide (CO2), water (H2O) and Oxides of nitrogen (NO2) in the complete combustion process of engine. These exhaust products are not considered as a pollutant but some additional products such as unburned hydrocarbon (HCs), carbon monoxide (CO), nitrogen oxide (NOx) and particulate matter (PM) create the most harmful effect on the environment as well as human. The quest to reduce these pollutants led to various technics such alternative fuels.........
