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 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

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.

Abstract

This study aims to determine the availability of Tilong Reservoir inflow related to climate change. Water availability can be seen from the high inflow into the reservoir, obtained using the Mock model to simulate the inflow. The modeling results using the Mock model in the historical period are then compared with the results of future projections using GCM CanESM2 data from SSP119 to SSP585 scenarios. The historical period is modeled using rainfall from 2000 to 2019, while the projection period is divided into two periods, namely the 2030s (2020-2039) and 2050s (2040-2059). The projection results show that the highest increase in rainfall will occur in the SSP245 scenario for the 2030s and 2050s. The highest increase in future rainfall occurs in June, while the highest decrease occurs in August. With the increase in rainfall, there will also be an increase in inflow into the Tilong Reservoir, especially in December, which is more than 100% for each SSP scenario. In addition, an increase in water availability can also be seen by an increase in the dependable discharge, especially at SPP245, where there was an increase in the highest dependable discharge of 64.23% in the 2030s and 76.80 in the 2050s. The increase in dependable discharge is seen to positively impact the water availability of the Tilong Reservoir. However, it is necessary to pay attention to the reservoir’s operational pattern so that the existing water can be used optimally.

Abstract

Establishing and maintaining hydrometeorological networks in sub-watersheds is challenging. An analysis of an established network of Rain Gauge Station (RGS) is provided in this study in the form of a comprehensive statistical framework. Hydrometeorological observations are monitored by this network, which aims to gather the most pertinent information while minimizing expenditures. The study location is at Ngasinan Hulu watershed (East Java, Indonesia), with ten rain gauge stations and one automatic water level recorder (AWLR). Errors in reviewing hydrological data in a watershed can cause the resulting data to be inaccurate. Therefore, to solve the problem of incorrect data, it is necessary to rationalize rain gauge stations. The rationalization for this study uses the Stepwise method. The results of the Stepwise-Enter method produce a combination of six rain gauge stations with measured rainfall data and a combination of four rain gauge stations with CHIRPS satellite rainfall data. Therefore, this combination of rain gauge stations is rational because it meets the classical assumption test, and the area is evenly distributed according to WMO standards.

Abstract

The increasing demand for drinking water due to population growth presents significant challenges for the Among Tirto Water Utility (ATWU) in Batu City, East Java, Indonesia. In 2022, ATWU faced low service coverage (36%) and high water loss (38%), exceeding the 20% threshold. Some previous research discusses the System Dynamics (SD) used to overcome the water shortage problem. In this study, the SD is used to overcome excess water. Therefore, This study aims to enhance efficiency by adding piping networks and controlling water losses. This research uses an SD approach method that includes simulations from 2017 to 2042 or for 25 years using the Powersim application. Methodologies include analyzing drinking water availability, constructing causal loop diagrams (CLD) and stock and flow diagrams (SFD), verification, validation, and designing policy scenarios. The required data are the number of customers, service coverage, actual production capacity, water loss, total community water consumption, business revenue, business expenses, and other data related to water management in ATWU. The study identifies Scenario Two as the most effective in addressing location-specific issues. If water loss control is implemented to reduce loss rates to 20%, ATWU could expand service coverage by 58.44%, increasing water availability and a projected profit of 3.6 billion rupiahs by 2042. The results of this study can improve operational efficiency and facilitate better decision-making for the Water Utility of Batu City.

Abstract

Microplastics found in drainage channels are a significant contributor to river pollution. Among the potential contributors to this issue are industrial activities. In this investigation, we focused on assessing the occurrence of microplastics within the Surabaya Industrial Estate Rungkut (SIER) industrial area, which discharges into the Tambakoso River in East Java, Indonesia. Surface water tests were obtained from 19 particular focuses. The extraction of microplastics included filtration, wet peroxide oxidation, and density separation techniques. Recognizable proof of polymers was accomplished utilizing Fourier change infrared (FTIR) spectroscopy. Statistical analysis was conducted employing the Ward cluster test method within the IBM SPSS Statistics software. The findings revealed a gradual increase in the abundance of MPs from upstream to downstream locations, with the highest concentration observed at point 19 (548.33 particles/L). The majority of microplastics were characterized by their small size (<1 mm), fragment shape (45.93%), and black color (56.18%). The types of polymers are mostly polypropylene (PP) and polyethylene (PE). Findings derived from the cluster analysis highlight the substantial involvement of the food and beverage, pharmaceutical, and plastics sectors in microplastic pollution within the drainage channels of the SIER industrial zones.
