Abstract

The Kalimas River, managed by the Surabaya City Government for both eco-tourism and as a crucial water source for the Kalimas River basin residents, undergoes comprehensive examination in this study. The objectives encompass assessing water quality status, mapping its distribution, and forecasting waste discharge. Employing the Pollution Index and Water Quality Index methods, findings indicate that, according to the Polluter Index, the water quality predominantly falls within the lightly polluted category, ranging from 76.19% to 90.48%. Conversely, the NSF-WQI method portrays a more concerning picture, categorizing the Kalimas River’s water quality as heavily polluted within the same percentage range. As of 2021, the existing waste discharge stands at 0.392m3/s, serving a population of 233,563 people. Mapping results highlight a general trend of good water quality downstream, with the Upper Kalimas experiencing more compromised conditions. These revelations underscore the critical need for strategic interventions and environmentally conscious policies to address escalating pollution concerns. Ensuring the sustainability of the Kalimas River, pivotal as both a tourist attraction and vital water source, requires concerted efforts in pollution mitigation and water quality management. This study serves as a valuable foundation for informed decision-making in the pursuit of a healthier and more sustainable Kalimas River ecosystem.

Abstract

Currently, Batu City is experiencing rapid development both in terms of population and the amount of land building. Where development is uncontrolled and not balanced by reasonable conservation efforts, it will cause water resource problems such as flooding. So, it is necessary to understand flow patterns better as an actual effort in effective water management and flood hazard mitigation. This study aims to obtain a map of flood-prone areas in the Brantas sub-watershed upstream of Batu City. The primary methodology adopted in this research entails the examination of surface runoff through the utilization of the ArcSWAT program, followed by the analysis of pertinent parameters, including rainfall, land use, soil type, land slope, river density, and surface runoff. Then, scoring and weighting are done before overlaying each parameter to get a flood vulnerability map at the research location. The results of this study indicate that the mapping of flood-prone areas at the most significant research location is at a high level of flood vulnerability of 78.31 km2 or 52.22% of the total area of the watershed.

Abstract

The major floods that occurred in 2022 in Lhoksukon, North Aceh, Indonesia, had a severe impact on infrastructure damage and loss of life, making it necessary to analyze and predict its impact. In this regard, digital methods can effectively analyze and predict the impact of such natural disasters. The digital method is processing digital data through software to produce the desired information. Based on the results of the digital analysis, it has been found that the flood discharge in the Lhoksukon area of North Aceh is around 1848 m3/second with a flow velocity of about 3.484 m/second. This high flow velocity can cause significant damage to the infrastructure in the affected areas. The flood height in the river area ranges from 9.545 m from the riverbed, which is a cause for concern. The increase in water level will cause an expansion of the inundation area in the river area, which can lead to further damage. Therefore, the results of this study can be used to develop effective flood mitigation strategies and infrastructure planning in the affected areas. Additionally, the study's findings can be used to develop early warning systems to alert people in the affected areas to evacuate before the floods reach dangerous levels.

Abstract

Road damage in the UB Forest Sumberwangi Area, Karangploso District, Malang Regency, is one of the harmful impacts of the drainage system. This study aims to analyze an accurate and efficient drainage system by applying modern methods, namely Building Information Modeling (BIM). By using BIM, the analysis of drainage work becomes faster and more accessible than with conventional methods. BIM is beneficial in building and analyzing drainage network data quickly and effectively and can help expand it to provide more accurate results. BIM can integrate models based on technical data and simulate development information into a three-dimensional model. BIM is used to perform 3D modeling of drainage channels using Autodesk Civil 3D, as well as analyzing channels from both hydrology and hydraulics with Storm and Sanitary Analysis (SSA). After calculating the design for a 5-year return period rainfall, channel dimensions of 50 x 50 cm and 30 x 30 cm were obtained. Based on the hydraulic analysis, it is known that several points have velocities that exceed the maximum velocity for the concrete surface (v < 3 m/s), so it is necessary to build a drop structure with h = 1 m. The quantity take off and the volume are calculated by Civil 3D for cut and fill work 7824.07 m3 and 1389.79 m3, respectively.

Abstract

The UB Forest Buntoro area is a biodiversity conservation zone that has the potential to be developed into a tourist forest, so it is planned to build a drainage channel in each section of the road to overcome the runoff that occurs. This research aims to describe an example of the application of BIM in construction planning for drainage channels. In this study, drainage channel planning was done using AutoCAD Civil 3D and Storm and Sanitary Analysis (SSA) software. The AutoCAD Civil 3D application is used to create a road route for which drainage channels are planned, and the SSA is used to analyze the hydrology and hydraulics of the drainage channel. Based on Building Information Modeling findings, the optimal drainage channel design yielded channel dimensions of 0.4 m × 0.4 m. The main channels (RC (Right Channel) and LC (Left Channel)) are planned to use gabion material, while the culverts are planned to use u-ditch material and a construction planning cost of 1.571.818.500,00 IDR. This study intends to give an example of how Building Information Modeling (BIM) is applied in Indonesia, particularly in the area of water resources. It does this by utilizing AutoCAD Civil 3D and SSA programs to design drainage channels.

Abstract

The construction of a check dam is proposed as a solution to address multiple environmental challenges in the upstream region of a river. Primarily, the focus is on erosion control, the deceleration of debris flow, and the prevention of sedimentation. The strategic implementation of this plan encompasses a range of methodologies, including topographical measurements, geotechnical testing, hydrological analysis, hydraulics analysis, and the meticulous development of a budget plan for the actual construction of the check dam. Within the study area, sedimentation issues stem from a debris flow characterized by a sediment discharge rate of 0.657 m3/s. This phenomenon coincides with a significant 25-year return period flood discharge of 9.134 m3/s. The proposed check dam emerges as a crucial intervention capable of effectively mitigating the situation for approximately 1 hour and 13 minutes, providing a targeted response to the persisting debris flow. To execute this plan, an estimated budget of IDR 460,859,000 has been projected. This financial allocation encompasses the expenses associated with topographical measurements, geotechnical testing, hydrological and hydraulics analyses, as well as the actual construction of the check dam. Overall, the proposed check dam stands as a multifaceted solution designed to harmonize environmental conservation with sustainable water resource management.

Abstract

This research confronts the pressing challenge of escalating clean water demand in Bandung, a dynamically expanding metropolitan city in Indonesia's West Java Province. Drawing on secondary data from the Central Bureau of Statistics and other relevant literature, the study leverages Microsoft Excel to perform a dual analysis: forecasting population growth and calculating future water demand through 2032. A pivotal outcome reveals that the existing water supply infrastructure in Bandung will be woefully insufficient to meet the exponentially growing clean water requirements. Uniquely, this study employs multiple forecasting methodologies, adding depth and reliability to the projections. It there by offers new, essential insights into the quantifiable volume of water that will be needed to sustain future urban development. The research argues that current supply-focused water management strategies are inherently flawed and calls for an immediate paradigm shift toward demand-side management to mitigate the impending water crisis. Specific recommendations include the incorporation of alternative water sources such as rainwater harvesting and groundwater recharge. Moreover, the study emphasizes the need for rapid governmental action, including policy revision and public education campaigns, to ensure water sustainability. This research stands as a critical resource for policymakers, urban planners, and water management experts aiming to bridge the looming water supply-demand gap in Bandung.

Abstract

The Lapindo mud phenomenon has been going on for 17 years, causing damage to the land and subsurface geological structures which raises concerns about reducing groundwater quality. This research aims to determine groundwater flow patterns based on surface contours around the Porong River which were analyzed using Surfer 13 software, and understand the relationship between groundwater and surface water through physical properties with correlation coefficients using Rstudio, as well as to identify the chemical characteristics of surface water and groundwater using the Trilinear Piper Diagram. Based on the research results, the groundwater flow pattern moves from northeast to southwest, and there is interaction between the two as indicated by the physical properties of the water. The correlation coefficient value ranges from 0.615 to 0.997, meaning that the relationship between groundwater and surface water is moderate to strong. Both groundwater and surface water have the same chemical type, namely mostly containing alkaline earth and weak acids. In addition, this research reveals the exploration of the impact of heavy metal parameters, namely Copper (Cu), from the Lapindo mud in the Porong River and residents' dug wells. In conclusion, this research shows the interaction between groundwater and surface water in the Porong River.

Abstract

A study was conducted on the Katingan tidal lowland area with hydro-topography A and B. The lowland area has good irrigation capability but low drainage capability, resulting in excessive inundation. This study aims to enhance drainage capability and control water levels in rice fields. HEC-RAS is used to model the hydrodynamics of canals and rice fields. There are three scenarios for improving the water system, namely embankments (1), embankments and pipes (2), and embankments, pipes, and gates (3). In the normalized canals, inundation in the middle of the rice field is more than 35 cm and continuous inundation. This is due to the low elevation of the middle area, which results in low drainage capability. The embankment (1) prevents the tide from overflowing into the rice fields, but the rice fields are deficient in water. Embankments and pipes (2) can fulfill the water need for irrigation but not increase drainage capability. Embankments, pipes, and gates (3) can maintain irrigation capability and improve drainage capability. The water level can be maintained at 7-10 cm at land elevation +3.40 m, but land with elevation +3.50 m has a water deficiency. The third scenario is the most appropriate for controlling water levels in rice fields. Water system improvement in tidal lowlands must be considered to avoid water deficiency. Drought in tidal lowlands causes pyrite to oxidize, leading to increased soil acidity. Therefore, irrigation capability must be maintained to improve the water system on land with hydro-topography A and B.
