Abstract

Land use change in river basins is an important issue for policymakers. In this case, it is essential to carry out comprehensive monitoring for decision-making. Land use monitoring must be carried out continuously so that changes that occur over a certain period can continue to be monitored. In this case, the Brantas Hulu watershed includes Batu City, Malang City, and Malang Regency. This river basin is considered critical due to massive land use changes. This condition directly encourages an increase in sedimentation rate in rivers and reservoirs. This research aims to obtain the results of monitoring land use changes and determine the handling of erosion rates by monitoring land use changes in the Brantas Hulu watershed. The method used to determine the spatial characteristics of soil erosion in the Upper Brantas watershed uses the Universal Soil Losses Equation (USLE) method. The research results show that erosion conditions in the Brantas Hulu watershed are dominated by class I/very light erosion hazards (36.43%). ), class II/light (22.35%), class V/very heavy (16.07%), class III/moderate (13.09%), and class IV/heavy (12.05%). The proposed control measures for erosion sites include structural and non-structural approaches.

Abstract

This research investigates planting strategies to optimize productivity and conserve soil, focusing on potatoes and onions grown on erosion-prone land. Cross planting versus perpendicular plantings is evaluated using the MOORA (Multi-Objective Optimization Based on Ratio Analysis) method based on erosion rates, crop productivity, and economic outcomes. Meanwhile, data from six experimental contour and perpendicular planting plots are analyzed. The measurements for sediment and runoff are carried out using a dual-bucket system. After erosion calculations, the highest erosion rate was found in the contour planting of shallots at 385,65 tons/ha/year. At the same time, Potatoes planted perpendicular to the contour lines resulted in the lowest erosion rate, at only 114.51 tons/ha/year. Economic analysis, considering crop productivity and financial outcomes, revealed the highest productivity for potatoes planted perpendicular to the contour at Rp. 26.891 kg/ha, and the highest Income for the contour planting of potatoes at Rp. 215.133.360/ha. Optimization using the MOORA method, which calculates minimal erosion (cost) and maximal Income (benefit), yielded the highest value for potatoes planted along the contour at 0.409963. This was followed by perpendicular planting (0.075816) and shallots along the contour (0.067163). The MOORA method can provide optimal planting pattern recommendations by analyzing multiple criteria, including soil erosion and productivity, thereby offering practical guidance to farmers and policymakers in making more economically viable and sustainable planting decisions.

Abstract

Irrigated agriculture accounts for more than 40% of global food production despite covering only about 20% of the world's agricultural land. However, climate change, water constraints, and multisectoral pressures on natural resources demand greater efficiency in the management of agricultural systems. One key strategy is determining optimal cropping patterns under conditions of water and land constraints. This study aims to review mathematical approaches, especially Linear Programming (LP)-based optimization models, in developing efficient and sustainable cropping pattern strategies. This study was conducted through a systematic literature review of 185 scientific articles from the Scopus and ScienceDirect databases in the period 2014–2025. The analysis was carried out using the PRISMA method and visualization of research trends through VOS viewer software. The results of the review indicate that optimization models, especially Linear Programs, have been widely used to develop data-based land and water allocation strategies, considering agronomic, economic, and environmental aspects. The increasing number of publications in the last decade reflects the urgency of this theme and the shift towards quantitative-based decision-making in agricultural systems. This study provides a conceptual and applicative basis for the development of sustainable planting strategies that are adaptive to environmental changes.

Abstract

The Bili-Bili Dam located in Gowa Regency, South Sulawesi Province, is a rockfill dam with a central core, featuring a total storage capacity of 375 million m³ and sediment storage capacity of 29 million m³. Due to its high risk of structural failure, Bili-Bili Dam is classified as Class IV (Extreme). Recent developments have shown a decline in dam body stability due to seepage issues. If left unaddressed, this could trigger piping or even structural failure, posing a threat to the sustainability of the reservoir's functions. The objective of this study is to evaluate the safety factor (SF) of the main dam, right wing dam, and left wing dam as an integrated structural system of Bili-Bili Dam. The approach combines both qualitative and quantitative methods, including engineering geological assessments and Geostudio SEEP/W to analyze seepage rates and SLOPE/W to evaluate landslide potential. The analysis results indicate that seepage discharge remains within acceptable limits, and the dam’s stability under Operating Basis Earthquake (OBE) conditions is considered safe. However, under Maximum Design Earthquake (MDE) conditions, the slope safety factor does not meet the minimum standard required by SNI 8064:2016. Therefore, remedial actions such as reinforcement or retrofitting of the dam body are necessary.

Abstract

Evapotranspiration is a key parameter used in run-off modelling. The Bulango Ulu Dam, located near the equator where sunlight is at its peak throughout the year, makes evapotranspiration a crucial factor in analysing water availability. This research aims to analyse the performance of two evapotranspiration calculation methods on the accuracy of run-off modelling to the Bulango Ulu dam. The study employs the modified Penman and Thornthwaite evapotranspiration methods as input to Mock's model. The Analysis indicates that the Mock-Penman method outperforms the Mock-Thornthwaite method, with statistical parameter results of MAE 0.963, NSE 0.891, R 0.949 and Kr 1.3%, Therefore, it concludes that the run-off modelling aligns with the observed flow value

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

The Epanet model in clean water pipelines is intended for time efficiency in calculating hydraulic behaviour. Calibration of the water pipe network is to compare the simulation results of the model to actual field observations and to see that the model that has been made is truly valid and reliable as a tool to determine the hydraulic behaviour of the network system when a change input into the system is given (e.g. the addition of pipelines and number of customer tapping debits). The pipe roughness coefficient (C) is a number that indicates the amount of energy loss due to friction between the flowing fluid and the pipe wall. The increasing age of the pipe will cause the pipe wall roughness to increase, and the energy loss will be even more significant. This research aims to calibrate the pipe network model by adjusting the C value of the actual pipe roughness coefficient according to the installed age. An initial simulation model was carried out by entering the standard pipe C value in the Hazen Williams energy loss equation in the Epanet link/pipe properties. Then a simulation is carried out by modifying the value of C according to the pipe's service life. For 600 mm steel pipe, change the C value from 150 to 87 (pipe age >30 years), HDPE 315 mm pipe changes in C value from 140 to 100 (pipe age >10 years) and 25-50 mm PVC pipe from 140 to 100 (pipe age >10 years). From the simulation results of the Epanet model-field observations, the average compressive height was obtained for five observation nodes.of 2 tails was performed paired sample test the pressure height value of the model-observation. Before modifying the value of C, the paired mean difference test results showed a significant difference between the simulation results of the model on field observations with a model significance value of 0.004, which means <0.005. There is a considerable difference between the simulations and observations, and the model is considered invalid. However, after modifying the value of C according to the actual age of the pipe, a paired sample test T average value of the compression model-observation was 0.098 > 0.005), which means that there is no significant difference between the simulation and observation. This means that the model made is quite valid. Product moment correlation between the model simulation height - field observations, the value of R = 0.967, the relationship is robust between the two results.

Abstract

In every reservoir plan, the volume of dead storage provided is always taken into account to accommodate sediment entering the reservoir during the service life of the reservoir. Several studies on reservoir sedimentation show that 70% of reservoirs have sedimentation problems so the effective life of the reservoir will end before the design life is reached. The rate of sediment entering the reservoir will settle in the dead reservoir and the effective reservoir which will affect the performance of the reservoir. Therefore, it is necessary to take measures to improve the performance of the reservoir, one way is to restore its effective reservoir. Based on the results of bathymetry measurements of the Kedungombo Reservoir from 1989 to 2017, the sediment rate was 1.954 million m3/year. From the analysis of sediment distribution, the dead reservoir of the Kedungombo Reservoir at an elevation of +65.00 will be filled in 2089. The effective reservoir in 2089 at a normal water level of +90.00 of 527.71 million m3 has decreased by 106.89 million m3 from the initial effective reservoir is 634.6 million m3. To improve reservoir performance by restoring its effective reservoir, the Kedungombo Reservoir requires an elevation of the overflow or normal water level as high as 2.26 m with an inundation area of ​​48.72 million m2.
