Abstract

Tanjung Perak Port in Surabaya, one of the biggest ports in Indonesia, faces significant sedimentation problems that can affect operational capacity. This research aims to investigate these sedimentation problems using a 3-dimensional numerical model with Delft3D software, analyzing wave, tidal, and topographic changes to recommend effective sediment management. This research focuses on Tanjung Perak Harbor in Surabaya, Indonesia, using Delft3D numerical modeling to analyze sedimentation phenomena and examine topography, tidal, wave, and sediment characteristics, and river inflow data from the Mas River and Lamong Rivers. This research divides the depth into three layers with the smallest grid size dx= 10 m and dy= 10 m. Sediment diameter data, used in this simulation with an average grain size (D50) of 0.28 mm from inside the port, will be simulated simultaneously with tidal and wave motion. This simulation is for 1 month using a scale factor of 12, making the simulation equal to 1 year. From the simulation results, the effect of wave movement is relatively small. At 3 locations in the Tanjung Perak port area, sedimentation with an average change in depth of 0.8 m/year was caused by sedimentation carried from the Lamon River and Mas River. Therefore, dredging recommendations are conducted to reduce sedimentation in the port area by constructing a jetty at the mouth of the Mas River. The results showed that the average depth increase changed to 0.4 m/year after the jetty was built, but some erosion occurred around the jetty, 0.0056 m/year.

Abstract

Energy infrastructure, particularly power plants, is critical in national and regional development. This study aims to determine the optimal placement and design of the Timika PLTU (power plant) by conducting comprehensive soil and rock investigations, focusing on seismic risks. The primary objective is to assess the geotechnical conditions of the site to ensure structural stability and safety in this high-seismicity zone. Key methods used in this study include borehole drilling, soil classification tests, and seismic hazard analysis. The soil at the site is classified as medium (SD) with Vs values ranging from 175 to 350 m/sec, and the seismic zone’s coefficient (Z) is 0.6, indicating significant seismic potential. The results reveal that specific design measures, such as sheet piles and retaining walls, are necessary to mitigate the risks of lateral collapse in areas with significant soil excavation. Furthermore, seismic design considerations were incorporated to improve the plant’s earthquake resistance. The findings of this study provide essential geotechnical data and practical recommendations, ensuring the safe and resilient construction of the PLTU Timika in a region prone to seismic activity while guiding future infrastructure projects in similar high-risk zones.

Abstract

Clean water is an essential element for human life. The need for water continues to increase along with population growth. Rivers are a good source of clean water. Understanding water availability in the river that we will use as a clean water source is very important. In 2022, Manado City will have a population of 454,606 people. This study aims to determine the water demand in Manado City in 2045 and whether the Tondano River will be able to meet the water demand by 2045. This research uses a quantitative method, where the data used includes Tondano River discharge data processed using the analysis of water resource availability and Manado City population data using exponential regression analysis. In 2045, the population is projected to reach 549,438 people. Water demand is calculated based on the domestic, non-domestic, and water loss sectors. The total water demand in 2045 was 1,860.08 liters per day. If the total water demand is added to the peak hour factor, the total water demand becomes 5,533.28 liters, while the mainstay discharge of the Tondano River for Q95 is 4,511.34 liters per day. It can be seen that in 2045, the Tondano River can still meet the clean water needs of the Manado community. However, if the peak hour factor for Q95 is added, the Tondano River cannot meet the clean water needs of the Manado people.

Abstract

Rain gauges in Indonesia are often unevenly distributed, with significant gaps in data availability. As an alternative, satellite precipitation products (SPPE), such as CHIRPS and GPM-IMERG, are increasingly used for precipitation estimates. Additionally, discharge data is frequently unavailable for extended periods, making rainfall-discharge modeling essential. This study aims to evaluate the performance of two SPPEs, CHIRPS and GPM-IMERG, in the Gembong watershed and identify the best rainfall-discharge model. The study focuses on black-box models, using precipitation as input and discharge as output, without discussing model uncertainty. The two SPPEs were compared using continuous statistics, categorical metrics, and volumetric indices. CHIRPS was found to outperform GPM-IMERG. Three models were then tested: the transfer function (TF) model, SARIMAX(1,0,0)(0,1,1)12(1,0), a hybrid SARIMAX-GRU model, and a standalone GRU model. The models were validated using correlation (r), Nash-Sutcliffe efficiency (NSE), and the ratio of root mean square error to standard deviation (RSR). The GRU model demonstrated the best performance, achieving r = 0.876 (very strong), NSE = 0.752 (very good), and RSR = 0.498 (very good). This research underscores the importance of accurate discharge prediction for water resource management in Indonesia. By applying innovative modeling techniques, the study contributes to improved water management strategies, with potential applications in flood management, agriculture, infrastructure planning, and policy development, ultimately supporting Indonesia’s broader sustainability goals.

Abstract

Floods are a natural disaster often experienced by the people of Indonesia, especially in Jakarta. In 2022, the government inaugurated the upstream area of ​​the Ciliwung River Basin. The research provides an in-depth analysis of the reductions achieved by the two dry dams across a range of return periods (Q), specifically 2, 5, 10, 25, 50, and 100 years, highlighting their performance in reducing peak flow volumes and their effectiveness in flood risk management under varying hydrological conditions. Currently, both do not have intake on their conduit channels. With this research, it is hoped that it can be determined whether or not the reduction results will be optimal by adding intake to their conduit channels. The results and analysis obtained on the Ciawi dry dam, namely Q2 can reduce up to 73.49%; Q5 can reduce up to 76.17%; Q10 can reduce up to 78.49%; Q25 can reduce up to 80.33%; Q50 can reduce up to 66.93%; and Q100 can reduce up to 54.98% while for the results and analysis of reduction in the Sukamahi dry dam for Q2 can reduce up to 78.40%; Q5 can reduce up to 82.24%; Q10 can reduce up to 83.38%; Q25 can reduce up to 84.41%; Q50 can reduce up to 84.94%; and Q100 can reduce up to 85.26%.

Abstract

Kalijompo sub-watershed is included in the Bedadung watershed of Jember Regency. Bedadung watershed is the largest watershed in Jember, and it has a land cover change. One of the factors influencing land cover change is forest fires, which cause a significant reduction in forest area. The significantly reduced forest area will impact increasing river discharge and result in flooding downstream. The downstream of Kalijompo is located in the city center of Jember, which has a dense residential area. Therefore, it is necessary to conduct a flood mitigation strategy. This research aims to assess flood risk and ideal land cover management so that this research can be used as a basis for designing flood disaster mitigation strategies due to land use change. The Soil Water Assessment Tool application models the flood response to land cover and determines sub-watersheds that contribute highly to watershed damage. The flood response model was used as the basis for simulation by creating several land cover scenarios to find the appropriate and optimal land use. Flood risk assessment was obtained by combining the components of flood hazard and vulnerability. Flood mitigation strategies were derived from the land use scenarios complemented by Strengths, Weaknesses, Opportunities, and Threats analysis to identify various factors. The results showed that Kalijompo contributed significantly to watershed damage, and 21.93% of the Kalijompo area was at a high flood risk level. One of the mitigation strategies is managing forest land use, which should be 30% of the total Bedadung watershed area.

Abstract

As a country in the tropics, Indonesia experiences drought almost yearly. However, prevention is still very slow, particularly in East Java Province, making it a prolonged problem. Meteorological drought is closely related to climate anomalies or weather instability that result in changes in rainfall patterns. Meteorological drought is analyzed using the EDI (Effective Drought Index) method. As a form of meteorological drought disaster mitigation, good and evenly distributed rainfall data is needed. Satellite technology such as CHIRPS can complement the uneven distribution of rain stations and areas difficult to reach by meteorological stations. The analysis shows that the worst drought occurred in 2005 with a minimum index value of -2.41, followed by 2007 (-1.94), 2012 (-1.55), 2017 (-1.62), and 2019 (-1.50). Based on the trend of drought events that occur every 2 to 5 years. This study’s results indicate that satellite rainfall data can help provide a more complete picture of drought conditions in the Slahung Sub watershed. With this study, an early warning system for drought mitigation is expected to be developed, and more effective measures can be planned to deal with future drought disasters in Ponorogo Regency.

Abstract

Reliable rainfall data is crucial for managing water resources, especially in agricultural regions like the Bodor Sub Watershed. This study comprehensively evaluates two precipitation products, the satellite-based CHIRPS dataset and the reanalysis ERA 5 dataset within the Bodor Sub Watershed. Both products were compared against gauge data at three timescales (monthly, 15-days, 10-days) for seven locations (Bodor Sub Watershed region and six rain gauges). Statistical parameters, including Nash Sutcliffe Efficiency (NSE), RMSE-observation standard deviation ratio (RSR), Pearson correlation coefficient (CC), and percent bias (PBIAS), were used to assess the performance of each precipitation product. Results consistently demonstrate that ERA 5 outperforms CHIRPS in most locations and time scales, particularly monthly. ERA 5 exhibited superior performance in over 85% of the analyses, with NSE values ranging from 0.164 to 0.862, RSR values from 0.992 to 0.372, and CC values from 0.507 to 0.932. ERA 5 also excelled in 57% of the bias analyses (PBIAS: -13.436 to 10.188). Regional validation consistently showed more favorable results compared to gauge-based validation. Additionally, data availability significantly influences product accuracy, with stations processing longer records exhibiting superior performance. This study offers valuable insights into the suitability of CHIRPS and ERA 5 hydrological applications in Bodor Sub Watershed, particularly in data-scarce regions. It contributes to improved water resources management strategies.

Abstract

Slow-release fertilizer (SRF) has become widespread in agricultural practices to reduce nutrient leaching, but the fertilizer coating has the potential to pollute the environment. Microplastics from fertilizer coatings can be released from paddy fields, enter drainage channels, and pollute rivers and the sea. This study uses paddy field modeling in planting containers to measure microplastic mass concentration and release pattern for 10 days from paddy fields under controlled conditions. This planting container was designed to resemble a paddy field equipped with soil, rice plants, and an artificial drainage system. A total of 81 mg of microplastics from the fertilizer coating was put into the planting container, and every day water samples passing through the hole were collected and analyzed in the laboratory to obtain the mass and pattern of gradual changes in microplastic concentration. The results showed that the highest microplastic release occurred on day 1 at 19.000 mg/L and the lowest at a concentration of 0.500 mg/L on day 6. Overall, the microplastic mass release has a downward trend pattern. High microplastic release on day 1 has a mass concentration of 19.000 mg/L, then decreases sharply at 2.333 mg/L on day 4, followed by a stabilization phase at low concentrations (2.000 - 0.500 mg/L). The total accumulated microplastic release during the study period reached 45.333 mg or 55.967% of the total input. These findings indicate that slow-release fertilizer coating contributes significantly to microplastic pollution in aquatic ecosystems.

Abstract

Precipitation variability significantly impacts water resource management, especially in regions like the Wonogiri Reservoir, which relies heavily on stable precipitation for agriculture, flood control, and water supply. This study investigates precipitation projections for the Wonogiri Reservoir area using CORDEX-SEA simulations under RCP 4.5 and RCP 8.5 scenarios for 2024–2050. Bias correction using Artificial Neural Networks is applied to improve the accuracy of the projections by aligning them with historical observations (1991-2005). The effectiveness of bias correction in 2006-2023 was evaluated using statistical metrics, including Pearson correlation coefficient (R), Percent Bias (PBIAS), and Mean Absolute Error (MAE). The results indicate significant improvements after bias correction. Correlation (R) increased by 13.75% and 17.63% for RCP 4.5 and RCP 8.5, respectively. As measured by PBIAS, systematic bias decreased by 61.09% (RCP 4.5) and 59.85% (RCP 8.5). Similarly, 61.12% and 59.84% MAE reductions were observed for the two scenarios. Post-correction, RCP 4.5 projections align more closely with historical observations, suggesting more stable precipitation patterns under moderate emission scenarios. In contrast, RCP 8.5 displays more significant interannual variability, with pronounced peaks and troughs, indicating increased risks of extreme precipitation under high-emission pathways. The study highlights the importance of integrating corrected precipitation projections into regional water resource planning and adaptation strategies to enhance resilience against future climate impacts. Further research is recommended to explore seasonal precipitation dynamics and extreme event frequencies under both scenarios.
