Abstract

Changes in land use, particularly the conversion of forests and agricultural land into urban settlements, alter hydrological responses by increasing runoff, raising peak discharge, and reducing baseflow. These changes affect flood risk, environmental quality, and the sustainability of built environments in rapidly urbanizing tropical regions. Aims: This study aims to systematically review applications of Soil and Water Assessment Tool (SWAT) and SWAT+ models to analyze hydrological responses to land use changes and evaluate their implications for urban flooding and sustainable built environments. Methodology and results: A Systematic Literature Review was conducted using Scopus-indexed and nationally accredited Indonesian journals. Studies were selected using keywords related to land use change, hydrological response, river basins, and SWAT or SWAT+ modelling. The results show that urbanization increases runoff, peak discharge, and sediment yield, while vegetation enhances infiltration and hydrological stability. Common parameters include streamflow, runoff, baseflow, and sediment yield. Performance is evaluated using NSE, R2, and PBIAS. Conclusion, significance and impact of the study: This review confirms that SWAT and SWAT+ support spatial planning and sustainable watershed management. It highlights the importance of integrating of hydrological modeling into land use planning to improve flood resilience and identifies gaps in future flood risk scenarios.

Abstract

The fluctuation of Cicatih River discharge presents a significant challenge in maintaining the operational performance of the Ubrug Hydropower Plant (HPP) in Sukabumi. Dependence on seasonal variations directly influences turbine efficiency and the continuity of electricity generation. This study aims to analyze the existing discharge of the Cicatih River, determine the efficiency of Ubrug HPP turbines, and evaluate the optimal discharge based on seasonal conditions. A quantitative approach was applied using the F.J. Mock hydrological simulation method to estimate discharge from rainfall data, potential evapotranspiration (PET), and watershed characteristics. Turbine efficiency was assessed through comparison of theoretical and actual power output during 2015–2024. Findings indicate that annual discharge varied from 12.13 m³/s to 17.65 m³/s, with turbine efficiency ranging between 83% and 86%, averaging 85.1%. The optimal discharge for maximum generation (≥15 m³/s) occurred mainly during the rainy season, whereas in the dry season discharge averaged about 12 m³/s, falling below the optimal threshold and reducing electricity output. Overall, the Ubrug HPP demonstrates stable and relatively high turbine efficiency, but maximum capacity is limited by seasonal discharge availability. Hence, integrated water management strategies are required to secure sustainable power supply and enhance operational efficiency of the plant.

Abstract

Purpose of the study: This study aimed to develop and validate an integrated precision aquaculture framework that combines IoT-controlled multi-prebiotic dosing, centralized environmental monitoring, and virtual reality-based operator training to improve water quality, fish growth performance, and operational competency in intensive multi-pond fish farming systems. Methodology: A closed-loop precision aquaculture system was implemented for 30 days in 40 homogeneous circular ponds. The system used centralized sensors (dissolved oxygen, pH, temperature), IoT-actuated solenoid valves with inline flow sensors for four prebiotic formulations, Water Quality Index computation, VR-based operator training, and statistical analysis using one-way ANOVA, multiple linear regression, and paired t-tests. Main Findings: IoT-based management significantly improved Water Quality Index, survival rate, and specific growth rate compared with manual management. Automated prebiotic dosing was volumetrically accurate and consistently on time. Higher water quality strongly correlated with better growth and survival. VR training substantially reduced operator task completion time and operational errors, enhancing overall system efficiency and reliability. Novelty/Originality of this study: This study presents a fully integrated multidisciplinary precision aquaculture framework that uniquely combines IoT-driven multi-prebiotic automated dosing, centralized environmental monitoring for homogeneous pond networks, and VR-based immersive training as an active human–system interaction layer. It advances current knowledge by demonstrating a scalable, technology-mediated model that unites automation, water quality management, and skill development in intensive aquaculture.
