Abstract

Pengelolaan sumber daya air sangat diperlukan untuk menjaga ketersediaan air, salah satu upaya dalam menjaga ketersediaan air adalah dengan membangun Waduk. Waduk Jragung merupakan Waduk multifungsi yang diharapkan dapat memenuhi penyediaan air irigasi, air baku, PLTMH, pengendali banjir, dan pemeliharaan sungai. Peramalan debit inflow waduk pada masa mendatang diperlukan untuk megetahui bagaimana pola pola waduk setelah bendungan selesai dibangun. Salah satu kendala dalam meramalkan debit inflow adalah ketersediaan data historis, terkadang data yang tersedia lengkap dan cukup panjang, tetapi terkadang ada juga yang tersedia terbatas atau relatif lebih pendek. Panjang data hidrologi yang mewakili suatu daerah pengaliran berpengaruh dalam proses perencanaan infrastruktur keairan. Tujuan dari penelitian ini untuk mengetahui pengaruh panjang data dan karakteristik debit bangkitan dengan metode Thomas-Fiering pada Pola Operasi Waduk Jragung. Berdasarkan hasil analisis masing-masing data seri memberikan keandalan yang berbeda-beda. Semakin besar rerata debit maka keandalannya dapat mecapai 100% dan luas layanan irigasi 4.053 ha dapat terpebuhi.

Abstract

Flooding in the Tuntang Watershed of Central Java, Indonesia, poses a significant threat to communities and infrastructure. Past mitigation strategy have been ineffective due to fragmented collaboration, limited community involvement, and insufficient policy support. This study explores a new approach that combines the Village Watershed Model (VWM) and the hexahelix collaboration framework to promote coordinated action among government, communities, academia, businesses, NGOs, and media. This research create hydrological and hydraulic modeling, analyzing stakeholder roles, collaboration levels, and flood risks using questionnaires as a method. Results indicated moderate overall collaboration, with government and community leading the efforts. The hexahelix framework proved valuable for identifying strengths, weaknesses, and opportunities for improvement. Recommendations include strengthening coordination, enhancing community participation, fostering multi-stakeholder partnerships, developing comprehensive policies and funding mechanisms, and continuing research and innovation.

Abstract

Landslides are among the most unpredictable and destructive sediment-related disasters, especially in mountainous regions with complex terrain and limited field accessibility. In 2004, a catastrophic landslide from the Mount Bawakaraeng Caldera delivered more than 100 million cubic meters (MCM) of sediment into the Bili-Bili Reservoir, filling its dead storage and threatening its long-term functionality. his study uses Sentinel-1A satellite imagery and Differential Interferometric Synthetic Aperture Radar (DInSAR) to perform a rapid, spatially driven assessment of landslide hazards in the Bili-Bili Reservoir Catchment Area. The results reveal surface deformation of up to ±1.55 meters, concentrated in upstream zones. High-risk areas span 71.00 km², with an estimated mobilizable volume of 110.04 MCM and a potential sediment yield of 27.14 MCM per year, nearly equal to the reservoir’s dead storage. To mitigate this threat, the study proposes an integrated mitigation framework. Structural interventions include rehabilitating existing sediment control systems and constructing new sabo dams. Non-structural strategies such as slope revegetation and bioengineering are also recommended. This study demonstrates how remote sensing can identify subtle ground deformation and provides actionable insights for safeguarding critical water infrastructure in sediment-prone tropical watersheds.

Abstract

Dam as water resources infrastructure has inherent failure risks, necessitating regular risk assessments to ensure its safety and functional sustainability. This study aims to evaluate the risk level of Titab Dam using two main methods: Event Tree Analysis (ETA) and the modified Andersen method. Hazard identification was conducted based on the 2024 inspection report, followed by failure mode analysis using FMECA (Failure Mode, Effects, and Criticality Analysis) to determine mitigation priorities. ETA results revealed that both individual and group extreme probabilities exceeded tolerance limits, requiring special interventions for several primary components, especially at the dam crest. Meanwhile, the assessment using the Andersen method produced a safety score of 66.33, categorized as ADEQUATE and still requiring corrective measures for defects found during inspections. This research provides an integration of two methods (ETA and Andersen) to strengthen the validation of dam risk assessment in Indonesia, thereby making the safety evaluation results more comprehensive and reliable. This study emphasizes the importance of implementing risk assessments as part of major inspections and ongoing monitoring activities to minimize failure potential and improve dam safety.

Abstract

Climate change is a global issue at present affecting the whole world, including tropical countries like Indonesia. Previous studies have indicated that changes in these conditions have grave impacts on hydrological disasters. Therefore, the pattern of climate change needs to be analyzed for the feasibility of adaptation and mitigation in the future. This present study developed analyses into the trend in temperature variation over East Java both on an annual and daily time scale. Observation data within a long period from 1985 to 2023 was used for comprehensive results. Methods applied include linear regression, the Man-Kendall test, and Sen's Slope test. The new finding that emerged for the temperature variable was that the increase in temperature went over the global and national averages and consistently showed a significant increasing trend across the study area. However, the rainfall variable revealed different results in highlands, where the rainfall intensity decreased-in SDII and R100, inversely proportional to coastal areas. It means that climate change does not occur uniformly everywhere but varies spatially. These findings raise a case for climate change mapping to formulate appropriate adaptation and mitigation strategies.

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.
