Abstract

Air conditioning (AC) systems are vital for ensuring thermal comfort in enclosed spaces, particularly in tropical regions like Indonesia, where high temperatures and humidity can challenge human productivity and well-being. This study investigates airflow distribution patterns in air-conditioned rooms using computational fluid dynamics (CFD) simulations, specifically employing the SST k-ω turbulence model. Simulations were conducted in a 3.5 × 3.55 × 3 m closed room with varied inlet temperatures (289.15–297.15 K) and airflow velocities (2–4 m/s). Results indicate that for every 2 K increase in inlet temperature, the average room temperature rises by approximately 1.37 K. Additionally, a 0.5 m/s increment in airflow velocity leads to an average temperature increase of 0.16 K. The airflow was observed to form a dominant jet stream from the AC inlet, flowing diagonally toward the lower part of the room, creating a low-altitude recirculation zone. This phenomenon influences thermal mixing and occupant comfort significantly. Validation of the CFD model revealed its robustness, with an average temperature deviation of 328.15 K and an Nash-Sutcliffe Efficiency (NSE) score of 0.858. Furthermore, the study suggests optimizing AC placement and operation parameters to enhance energy efficiency while maintaining comfort. These findings provide actionable insights into airflow behavior in tropical environments, promoting better design practices for cooling systems, which are crucial for sustainable development and improved living conditions in tropical climates.

Abstract

Post-mining land use sustainability is critical for mitigating environmental degradation and ensuring long-term community benefits. This study identifies gaps in participation and highlights innovative strategies for addressing trust deficits in land management. Through advanced statistical methods such as Structural Equation Modeling (SEM), the research pinpoints the pivotal role of transparency and trust-building in driving community engagement. Additionally, the study explores the implications of global best practices in land rehabilitation and how these can be adapted to local contexts like Pongkor, Bogor Regency. By integrating insights from international case studies, this analysis underscores the need for tailored community outreach programs that align with cultural and socioeconomic dynamics. The findings contribute to broader discussions on sustainable practices and provide actionable recommendations for policymakers to enhance the effectiveness of post-mining rehabilitation efforts.

Abstract

The global energy crisis and continued reliance on fossil fuels have intensified the search for sustainable alternative energy sources, particularly biomass-derived biofuels. One promising yet underutilized resource is the peel waste of Carica pubescens, a papaya variety indigenous to the Dieng Plateau. This study investigates the potential of Carica peel waste as a bioethanol feedstock through sulfuric acid (H₂SO₄) hydrolysis and fermentation using Saccharomyces cerevisiae. To optimize sugar yield, the concentration of H₂SO₄ was varied between 0.1 M and 0.8 M, while fermentation durations were set at 96, 120, 144, and 168 hours. Results indicated that hydrolysis with 0.8 M H₂SO₄ produced the highest sugar concentration (6.8%). The most effective fermentation period was 120 hours, yielding 64% bioethanol with a density of 0.8679 g/mL, a calorific value of 4,831 kcal/kg, a flame height of 14.6 cm, and a combustion temperature of 438°C. These findings demonstrate the viability of Carica peel waste as a valuable raw material for bioethanol production. Its high efficiency and favorable fuel properties highlight its potential for integration into local renewable energy initiatives, contributing to sustainable energy development. Further studies on large-scale implementation and process optimization are recommended to maximize its industrial application.

Abstract

This study employs integrated geophysical methods to analyze the spatial distribution and subsurface geometry of andesitic rock formations in the Mujil Hill area, Kulon Progo, Yogyakarta. Electrical resistivity imaging (ERI), using a dipole-dipole configuration, was conducted to identify high-resistivity zones (>1000 Ωm), which are interpreted as fresh andesitic intrusions. These zones are consistently found at an average depth of 10 meters, embedded within moderately resistive volcanic breccia. Near-surface layers with low resistivity values (<100 Ωm) are associated with weathered volcanic deposits or unconsolidated soil. To enhance subsurface structural interpretation, resistivity data were complemented with gravity modeling, providing a more comprehensive geological assessment. The results confirm the lateral continuity and shallow emplacement of andesite bodies, highlighting their potential as a local source of construction material. This integrated geophysical approach supports sustainable mineral resource development and aligns with the objectives of the regional economic empowerment program, contributing to the responsible utilization of local geological resources.

Abstract

Previous studies have revealed significant hydrothermal alterations within the Beruang Kanan Non-Volcanic Area, Central Kalimantan, Indonesia, resulting in extensive ore mineralizations. This study aims to examine the effects of hydrothermal processes on rock alteration, delineate alteration zones, and establish their relationship to metal mineralization. The research area, situated in the Tumbang Miri district of Gunung Mas regency, forms part of the Corrugated Hills Geomorphological Unit and is traversed by the Schwaner Mountains, with elevations ranging from approximately 50 to 400 meters. Stratigraphic analysis identifies three primary rock units, ordered from oldest to youngest: the Tuffaceous Sandstone Unit, the Dacitic Tuff Unit, and the Andesite Unit. Hydrothermal alterations have resulted in three distinct alteration zones sericitic, argillic, and propylitic characterized by secondary mineral assemblages. This study provides a comprehensive framework for understanding the geological and mineralization dynamics of non-volcanic hydrothermal systems in Central Kalimantan, Indonesia
