Abstract

River pollution is a significant environmental issue driven by urban growth and industrialization. The Cikakembang River, a tributary of the Citarum River in the Majalaya industrial area, receives wastewater from densely populated residential areas and textile manufacturing industries. Accurate assessment and monitoring of surface water quality are crucial to ensure its safe utilization. This study investigates the the Cikakembang River's water quality using the Pollution Index, STORET, and CCME-WQI methods, evaluating 14 water quality parameters across nine sampling locations during both wet and dry seasons to capture seasonal differences. The results reveal that the river fails to meet Class II water quality standards as outlined in Government Regulation No. 22 of 2021. While the Pollution Index classified contamination as mild to moderate, both STORET and CCME-WQI consistently indicated severe pollution across all sites and seasons. These findings suggest that STORET and CCME-WQI provide a more comprehensive assessment of pollution severity than the PI method, which may underestimate cumulative water quality degradation. This study highlights the urgent need for enhanced pollution control measures and stricter regulatory enforcement to mitigate further degradation of the Cikakembang River and improve its long-term sustainability.

Abstract

Indonesia’s is focusing the electricity power production from non-renewable sources to renewable energy resources. Hydropower might be promising; however, its production is highly affected by seasonal variability. Matenggeng dam is designed as multipurpose dam, namely for supplying the irrigation system, flood control, and utilization in a hydropower system. Based on its design report, the Matenggeng Dam is planned to produce power of about 11.74 MWac at water elevation of +194 m. Due to seasonal variability, the power production decreases to 5.74 MWac at the lowest water elevation. Solar energy, on the other hand, has a great potential in Indonesia, this study is aimed to optimize the decrease in existing electricity production in Matenggeng Dam by hybridization of hydropower with floating solar power plants. According to the regulation of Indonesia’s public affair only 20% of the water surface area at normal condition can be used. By taking into account the reservoir operation pattern and the reservoir various conditions, the optimum water surface area that can be used for FPV installation is 295.7 hectare. The result showed that, the solar power plant successfully produces 14 GWh of energy annually, where the monthly generation is stable at 1,200 MWh per month.

Abstract

High rate of pollution on the watershed has impacted to deteriorate water quality reservoirs. Officially, Quality Status of Reservoir Ecosystem has not been established yet. So, this study describes the accomplishment of integrated watershed management using Quality Status of Lake Ecosystem criteria (SMED) formulated by ministry of environment. The application of the criteria to Saguling and Sutami reservoirs datas shows that quality status of the reservoir ecosystems are in threat conditions. In order to apply the SMED criteria for assessment of quality ecosystem in reservoir, the advance experiments are still needed mainly for the additional indicators as following: 1) integration blue­algae and biodiversity indicator with biodiversity index; 2) suitability of land erosion indicator connected with reservoir design of erosion rate; 3) shifting of siltation lake indicator siltation reservoir indicator in relation with the percentage of dead storage volume; 4) integration hydroelectric power and water resources exploitation associated with the hidrological reservoir and water balance; 5) suitability of fish cage calculation in reservoir, 6) suitability of water quality indicator related with water quality standard; 7) addition of corrosivity index and quality of bottom sediment in reservoir. To facilitate apply the SMED for the assessment of reservoir ecosystem.

Abstract

The Western North Tarum Irrigation channel plays a crucial role in supplying water to irrigated agricultural areas. However, it encounters challenges in ensuring adequate water delivery to all channel segments. This research assesses water loss during the distribution process in the Western North Tarum Irrigation channel, focusing on the evaluation of channel capacity and the impact of suboptimal water management on water loss. The study employs the HEC-RAS model, a hydraulic system analysis tool, to evaluate the channel’s capacity and simulates its behavior under various discharge conditions. The evaluation reveals that two channel segments, B.TUB 13 and B.TUB 25, have exceeded their capacity limits, resulting in overflow. Sedimentation downstream, particularly in these segments, exacerbates the issue by altering the channel slope and impeding water flow. This research identifies poor water distribution management as a significant factor contributing to water loss in the irrigation channel. Inadequate scheduling and the absence of proper water measurement tools result in instances of overwatering or underwatering in some areas. The lack of monitoring and control in the irrigation system hampers the detection of uncontrolled flow in the channels, leading to substantial water loss and inefficient water use. This research underscores the importance of evaluating and maintaining irrigation channel capacity to prevent overflow and water loss. Furthermore, it emphasizes the significance of effective water management to achieve more efficient water distribution and irrigation. Addressing these challenges is crucial for ensuring the long-term sustainability of irrigated agriculture in the Western North Tarum Irrigation area.Keywords: HEC-RAS, Irrigation Channel, Water Distribution, Water Loss, Western North Tarum

Abstract

Sawahlunto Conservation Park is an area developed for plant protection and tourism activities. The Sawahlunto city was initially built to support coal mining activities, so the conservation park has several basins that can be used as flood parking ponds. These basins can be used to meet the needs of watering plants. The study is used to examine the water availability and flood analysis at the area to be built.  The conservation park is divided into three areas based on the four reservoirs location: the Kandih Park area, the northern and the southern part of the parking area. In this study, hydrologic and hydraulic analyses will be conducted. In the hydrological analysis, simulations of reservoir capacity are carried out to describe the amount of water that can be used every month. In the hydraulic analysis, SWMM program is used to model rainwater as surface runoff, estimate the planned channel dimensions, and reservoir flood volume. The reservoir simulation results show that the water needs for watering plants can be fully met. However, the available storage ponds have a much smaller volume than the rainfall volume, so the pond will run off throughout the year. The SWMM modeling results show that the channel dimensions from 0.2 m x 0.2 m to 0.5 m x 0.5 m, can drain flood discharge with a two-year return period, with a freeboard five-year return period. This study can be used as a guideline for developing conservation areas in reusing the potential of ex-mining land.

Abstract

Flooding is one of the most frequent natural disasters in Indonesia. Based on data, as of 2024, there have been 137 cases of flooding incidents. One of the causes of flooding, particularly in urban areas, is due to land use change. This study examines the impact of land use changes on runoff discharge in a Church area in the Bandung City. Additionally, this study investigates the effect of the development of this area on flood water levels in the Riung channel, which serves as an outlet channel. In this study, modeling is conducted using the SWMM model. The study utilizes data from the BMKG Bandung and GPM satellite rainfall data from 2001 to 2022 for rainfall analysis. The results indicate that in the study area, the duration of extreme rainfall producing maximum discharge is rainfall lasting for 7 hours. As a result of the church development, runoff discharge increases by 26.3 – 34.4% across various return periods. For time to peak, there is no significant change in conditions before and after the area is developed. This is due to area is relatively small, resulting in a relatively shorter concentration time. Based on the hydraulic analysis, the Riung channel is still able to accommodate additional runoff generated due to development, leaving a freeboard height of 4.5 cm for a 10-year return period. However, based on observations, special attention is needed regarding the issue of sedimentation and trash, which often causes backflow in several segments of the trenches.Keywords:runoff, land use change, urban drainage, SWMM, Bandung

Abstract

Bogor City, with a population of approximately 1,064,000 in 2022 and an annual growth rate of 2.01%, faces increasing pressure to meet housing demands. To accommodate this need, one modern residential development in the area has undergone extensive expansion. A previous assessment indicated that the development of a 10.75-hectare residential area in this neighborhood could increase peak discharge by approximately 24.74% for the 2-year return period and 16.67% for the 5-year return period.Based on these findings, this study aims to evaluate the effectiveness of Low Impact Development (LID) measures, specifically the use of rain barrels, in mitigating the hydrological impacts of land-use changes. Simulations were conducted using the Storm Water Management Model (SWMM) to: (1) analyze changes in peak discharge and runoff volume before and after development; (2) design the residential drainage system while testing different rain barrel capacities; and (3) evaluate the effectiveness of rain barrels in reducing peak discharge and runoff.Simulation results indicate that the installation of two rain barrels per household, each with a diameter of 1.41 m and a height of 1.19 m, can reduce peak discharge by 19.66%, approaching pre-development conditions. However, total runoff volume remains higher than baseline levels, suggesting that additional LID strategies are necessary for more comprehensive flood mitigation. These findings underscore the potential of rain barrels as an effective tool for urban runoff management and provide practical guidance for optimizing their implementation in similar residential developments.
