Abstract

Water supply and demand are the most discussed issue in the world including in Indonesia. Java with the largest population and center for industrial and agricultural activities in Indonesia faces problems in water availability and water demand. This condition illustrates the potential of Java to experience water scarcity. This study analyzes water status in Java using the water balance approach and Water Scarcity Index. The analysis was carried out to evaluate changes in the annual water balance during a period of the 10-year average (1981-1990, 1991-2000, and 2001-2010). The rainfall data from CHIRPS and air temperature from CRU were used to calculate water availability. Water demand is calculated for the domestic, industrial, agricultural, and environmental sectors based on Indonesia water use standards. The results indicate that the average water availability in Java varies in each period. The highest water availability occurred in 1981-1990 (160 billion m3/year), while the lowest was in 1991-2000 (149 billion m3/year}. The water availability decreased from 1981 to 2010, on a per capita basis. The water scarcity index also changes every period. The area experiencing a water deficit as described by their water scarcity index as a very critical class. Moreover, DKI Jakarta and East Java Provinces are in very critical condition with more than 50% area. Based on the study results, evaluation of water balance and water scarcity index can be used to describe the water status in a certain area as the reference for decision-makers in determining programs in water resources management.Keyword: Water status, water balance, water resources management, water scarcity, spatial analysis

Abstract

 UB Forest Sumbersari is a forest for multidisciplinary research and development in Brawijaya University. In order to improve and reducing the environmental damage around the road due to water flow, the planned drainage system by implementing BIM. BIM has a major role in coordinating and integrating information exchange and knowledge between various disciplines and phases in the project implementation. In this study, the Autodesk Civil 3D and Autodesk Storm and Sanitary Analysis (SSA) are employed as a BIM platform. Autodesk Civil 3D is the latest version of AutoCAD Land Desktop development that has used the dynamic modeling concept. Autodesk Civil 3D helps facilitate in case of design changes as well as in the calculating of job volume such as the volume of cut and fill of the soil and volume of required materials in drainage channel planning. While SSA facilities plan on hydraulics such as flow depth, maximum velocity, channel slope, and channel dimensions. Based on the result of the SSA analysis, the dimensions of drainage channel are 30 cm x 30 cm, 50 cm x 50 xm, 65 cm x 65 cm, and 80 cm x 80 cm. And generated volume of cut equals to 3148,02 m3, while the volume of fill equals to  296,93 m3, with total required volume of gravel reaches 444,8 m3. Keywords:   drainage, Building Information Modeling, Autodesk Civil 3D, Storm and Sanitary Analysis,  UB Forest Sumbersari

Abstract

The growth in population over time requires improvements in infrastructure services, which often lead to changes in land use within watersheds. These changes frequently result in the ground surface becoming more impervious, ultimately increasing runoff discharge. Land use changes have a significant impact on the Cp and Ct parameters within watersheds. To assess the impact of land use changes, we conducted research using the Snyder Synthetic Unit Hydrograph (SUH) Method on the Code Watershed in 2016 and 2020. Determining the Ct and Cp parameters is essential in predicting peak discharge. Cp is a characteristic watershed parameter that naturally changes as the watershed itself changes, while Ct is a parameter related to watershed slope, which also varies with changes in land use. The analysis shows an increase in the values of both parameters over the two different time periods, leading to an increase in peak discharge. In 2016, Cp and Ct values were 0.40 and 1.80, respectively, with a peak discharge of 0.47 m³/s. By 2020, these values had risen to 0.60 and 1.85, with a peak discharge of 0.68 m³/s. The increase in the Cp parameter indicates that the Code Watershed has become more impervious, reflecting a change in its characteristics. Similarly, the increase in the Ct parameter indicates changes in the watershed slope due to land use constraints. The RMSE calculation results show that the SUH Snyder prediction is consistent with the unit hydrograph calculations.Keywords: land use, discharge, Cp , Ct , SUH Snyder

Abstract

Groundwater recharge is a crucial factor in determining the permissible groundwater extraction within a watershed. In the Cikapundung watershed, the contribution of groundwater to raw water supply has been continuously declining, prompting a shift from groundwater to surface water usage. This study aims to quantify the groundwater recharge volume and recharge coefficient for each geological formation within the Cikapundung-Gandok watershed, covering an area of 90.4 km², and to compare the results with previous studies. The analysis estimates recharge volumes based on rainfall data from 8 stations around the Cikapundung-Gandok watershed from 2010 to 2019, geological formation data, and alternative recharge coefficients. The difference in recharge volume from previous studies is 393,348 m³/year or 1%. Two formations, Qvu and Qyu, which were not identified in earlier studies, supplement the existing geological dataset. The selected recharge volume for the Cikapundung-Gandok watershed is 33,232,004 m³/year or 1.05 m³/s, with the lowest contribution from the Lava formation (Qyl) at 1,364,504 m³/year or 0.04 m³/s and the highest from the Old Volcanic Product (Qvu) at 14,072,243 m³/year or 0.45 m³/s. The tentative recharge coefficients for each rock formation are as follows: Colluvium (Qc) 30%; Unweathered Old Volcanic Product (Qvu) 20%; Sand Tuff (Qyd) 10%; Lava (Qyl) 25%; Pumiceous Tuff (Qyt) 20%; and Young Volcanic Product (Qyu) 20%. The groundwater recharge data obtained can be used to set groundwater extraction limits and to plan for groundwater management using a conservative approach to ensure long-term sustainability.Keywords: groundwater recharge, recharge coefficient, geological formation, groundwater exploitation, Cikapundung-Gandok Watershed

Abstract

Desa Kambuhapang and Desa Kambatawundut are villages located in the Lewa District of East Sumba Regency. This area is characterized by arid conditions and experiences an 8-month-long dry season. Most of the population in this region is engaged in agriculture, particularly dryland farming. The main water supply for agriculture in this area comes from low rainfall, resulting in limited water availability. The purpose of this study is to assess the water discharge potential in these two villages. Secondary data, including rainfall data, was obtained from two stations: the Waingapu meteorological station and the Lewa Paku rain station. Additionally, climatological data from 2012 to 2021 was used. ArcGIS 10.7 software was employed to map the area using Digital Elevation Model (DEM) data. The Modified Penman method was used to determine evapotranspiration, while the F.J. Mock method was applied to calculate the reliable discharge. The results showed that the average annual water availability, according to the F.J. Mock method, is 16.45 m³/s for the Lay Mbeda River and 16.54 m³/s for the Wai Wei River. The villages of Kambuhapang and Kambatawundut have sufficient water availability, with a total of 74.18% across an area of 63.12 km². The adequate water availability in these two villages is evident from the minimum discharge during the dry season, ranging from 6.60 to 7.12 m³/s. This indicates that the villages have sufficient water resources to support the expansion of productive agricultural land for the local community. The utilization of these water resources could be further optimized by providing supporting infrastructure to increase runoff storage, such as water reservoirs, small ponds, or retention basins.Keywords: mapping, water potential, water availability, waingapu, lewa paku

Abstract

Rainfall plays an important role in hydrological and environmental planning. Meteorological conditions affect rainfall through its intensity, amount, and duration. However, heavy rainfall can cause significant damage and loss. Research was conducted in the Upper Citanduy watershed, West Java, using rainfall data from 8 stations over a range of 5–14 years. The study took a heavy rainfall event threshold of ≥ 50 mm in 24 hours. The research aims to analyze the dominant heavy rainfall patterns in the Upper Citandyu watershed. Empirical analysis used the Mononobe Method and Alternating Block Method (ABM), while rainfall distribution was analyzed with Inverse Distance Weighted (IDW) using Geographic Information Systems. The dominant heavy rainfall duration in the Upper Citanduy watershed occurred over 4–6 hours. Rainfall distribution analysis showed a pattern that was not influenced by the elevation of the rainfall station. The analysis results show that the Mononobe Method is closer to the dominant observed heavy rainfall distribution for 4 hours, while ABM is closer to the durations of 5 and 6 hours. The suitability of the distribution pattern was measured using Correlation (r), Root Mean Squared Error (RMSE), and Nash-Sutcliffe Efficiency (NSE) criteria, with Mononobe providing better results than ABM method. This research contributes to the understanding of rainfall patterns that can form the basis for analyzing designed rainfall intensity as a step in flood disaster mitigation in the Upper Citanduy watershed.Keywords: heavy rainfall, rainfall distribution pattern, rainfall intensity, upper Citanduy watershed, geographic information system

Abstract

In recent years, students and academic staff at the Faculty of Engineering, Universitas Pancasila, South Jakarta, have experienced domestic water shortages due to insufficient water supply. To address this, a rainwater harvesting scheme utilizing AARS (Artificial Aquifer and Rainwater Storage) and NARS (Natural Aquifer and Rainwater Storage) systems is proposed. Calculations indicate the need for 16 standard AARS units, but two alternatives have been designed to reduce costs and optimize available land. Alternative 1 proposes 6 AARS units (9.30 m x 3.33 m x 2.50 m) with maintenance wells measuring 1.50 m in diameter and 7 m in depth, while Alternative 2 consists of 3 units (9.0 m x 5.29 m x 2.50 m) with similar maintenance wells. Both alternatives offer a water production capacity of 4,350 liters/day. Additionally, the remaining 998 m² of roof area will be utilized in a shallow NARS scheme. In a 20 m x 35 m parking lot, 20 NARS units and 2 utilization wells are planned, with excess water discharged into surrounding areas. The combined AARS-NARS system can meet the Faculty’s daily water demand of 6 m³, with AARS supplying 4.35 m³ and NARS covering the remaining 1.65 m³. This system combination has the potential to be a sustainable solution for urban water needs, with its implementation expected to serve as an efficient water management model, especially in urban environments.

Abstract

The construction of the Piam River weir is one of the efforts to support food security for the community, especially in Langkat Regency. Increased water levels in the rainy season with high intensity and long duration can cause rapid changes in the return flow with large volumes in the upper reaches of the river. Changes in the return flow can cause flooding in the river plain, resulting in a risk of loss to the community. One of the initial nonstructural efforts in flood mitigation is to delineate flood inundation areas through hydraulic simulation modelling based on the 100-year return period maximum flood discharge, longitudinal and transverse river profiles, and weir profiles. Modelling simulations were carried out using HEC RAS Software in a 2-dimensional manner based on 100-year return period flood discharge data as boundary conditions upstream, DEMNAS as a base map of the river geometry profile, and weir dimensions as boundary conditions downstream. The results of modeling the flood inundation area with a 100-year return period flood discharge of 239.66 m3/det show that the maximum potential flood water level reaches 3 m inundating the plain area up to 500 m from the river bank. The flood inundation area that occurs reaches 390.21 ha so that flood control efforts are needed by building embankments and normalizing the river upstream of the weir.

Abstract

Accuracy of rainfall data is very important in hydrological analysis, especially in areas with limited data such as Labuan Bajo City, Indonesia. Global climate data generated from satellite observations and assimilation products, which are freely available, have great potential for use in data scarce areas. However, this data needs to be evaluated to measure its accuracy in rainfall estimates. This research aims to evaluate the accuracy of eight global rainfall data products, namely Global Precipitation Measurement (GPM), Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN), Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks – Cloud Classification System (PERSIANN-CCS), Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks - Climate Data Record (PERSIANN-CDR), Precipitation Data Integration and Retrieval - Now (PDIR-Now), European Reanalysis for the 5th Generation (ERA5), European Reanalysis for the 5th Generation Land (ERA5-LAND), and Climate Hazards Group InfraRed Precipitation with Station Data (CHIRPS) at two temporal scales: monthly and 15-daily. Evaluation is carried out using an assessment matrix which includes Root Mean Square Error (RMSE), Nash-Sutcliffe Efficiency (NSE), correlation (r), and Relative Bias (RB). The evaluation results show that on a monthly scale, ERA5, PERSIANN, and GPM provide the best results, with ERA5 being the top. On a 15-daily scale, ERA5 also shows the best performance, followed by GPM and ERA5-LAND. These findings confirm that ERA5 is the main choice for monitoring rainfall in Labuan Bajo City, which is very important for water resource management in areas with limited direct observation data.

Abstract

Water availability is a crucial factor that must be considered in the planning and management of irrigation systems. This study aims to determine water requirements based on a proposed rice–rice–secondary crops cropping pattern in the Oepunu Irrigation Area. This irrigation area encompasses 111 hectares of functional land and 20 hectares of potential land, with the current cropping pattern being rice–secondary crops. To ensure sufficient water supply, a study is necessary to design an effective cropping pattern. This research employed the Modified Penman method to calculate evapotranspiration, the F.J. Mock method to estimate dependable discharge, and direct streamflow measurements. The dependable discharge obtained ranges from 1,02 to 8,38 m³/s. The average discharge from direct measurements during the dry season (May-II to July-II) was 0,26 m³/s. The irrigation water requirements for the alternative cropping patterns are as follows: Alternative I ranges from 0,02–0,32 m³/s, Alternative II from 0,03–0,30 m³/s, and Alternative III from 0,03–0,24 m³/s. Based on the calculations, the maximum irrigable land area is 316.49 hectares for Alternative I, 274.95 hectares for Alternative II, and 948.87 hectares for Alternative III. These figures exceed the available land area, indicating that the selection of a cropping pattern must be based on the planned discharge derived from both irrigation water requirement calculations and field measurements. The planned discharge values are 0,32 m³/s for Alternative I, 0,30 m³/s for Alternative II, and 0,24 m³/s for Alternative III. Based on these planned discharge values, the most suitable cropping pattern is Alternative III, with a planned discharge of 0,24 m³/s and measured available discharge of 0,26 m³/s.
