Management of water resources in a river basin requires a new approach. The availability of water is a basic thing that must be considered given the increasing need for water. This study aimed to develop a water balance model in the Upper Bekasi River Sub Basin. In this study water balance model of the Bekasi River Sub Basin was built with several variables that affect water demand and availability, namely population growth rate, public facilities, and efforts to utilize resources. In this research, water supply and demand modelling was carried out using a dynamic system supported by Vensim software. Simulations were carried out from 2012 to 2045. The increase in population growth was directly proportional to the increased in population water needs. This dynamic model simulation used the application of rainwater harvesting and water-saving behaviour. Water demand for the Bekasi River Sub Basin was equal to 156.649.000 m3/year. The availability of surface water was 138.127.680 m3/year and had not been able to meet the water needs. The dynamic model showed that the water balance will be deficit in 2031, namely 51.883.200 m3/year. However, with the application of the water saving scenario, the water balance has a surplus of 258.564.000 m3 / year until the end of the simulation. Water reducing behavior can be used as an efficient method of water utilization. Keywords: Population, Rainwater harvesting, Simulation, Water management, Water resource

“…The use of groundwater to meet water needs in the UNDIP Campus area for 2014/2015 was 2.23 lt/s, exceeding the permitted optimum debit for well water withdrawal, namely 0.2-1 lt/s. Based on this, plans were made for a rainwater building with a volume of 245 m 3 with dimensions of 7m x 7m x 5m and dimensions of an infiltration well with a diameter of 1.5 m and a depth of 3 m [3].…”

Heavy rain that occurs on the State University of Malang campus often results in puddles. With the large water catchment area in the campus area and the many locations where rainwater pools, it is necessary to research how much rainwater can be collected. The methodology used includes collecting rain data, observing inundation locations, calculating rain using the ranking method, rational method debit calculations, water balance calculations, and storage size calculations. From the survey results, the locations that can be used as reservoirs consist of 14 locations. The area of the catchment area that has the potential to drain water into the reservoir is 69,845.10 m2. The storage capacity calculation results obtained: G1 = 178.50 m3, G1 = 80 m3, G3 = 75 m3, G4 = 108 m3, G5 = 97.5 m3, G6 = 93.6 m3, G7 = 84 m3, G8 = 22.5 m3, G9 = 67.2 m3, G10 = 83.2 m3, G11 = 41.6 m3, G12 = 36.4 m3, G13 = 65 m3, G14 = 65 m3. The amount of standing water that can be accommodated in the storage pond is 852.72 m3. The amount of standing water that can potentially be stored for 1 year is 19,553.98 m3.

“…This is done to accommodate the water that accumulates during the rainy season and to provide water during droughts, and water shortages, as well as to mitigate floods and droughts [8]. The significance of planning for the provision of empty spaces for rainwater harvesting as a form of water conservation awareness has been reported by [9] Studies and planning for the provision of empty spaces for rainwater harvesting have been conducted at the campus of Diponegoro University in Semarang. The development of the campus, which transformed approximately 50 percent of the university campus area into buildings, has been acknowledged by researchers to have led to a reduction in green open spaces for rainwater absorption, resulting in floods and waterlogging during the rainy season and water shortages during droughts.…”

The water crisis caused by floods and droughts has become an urgent problem in many regions worldwide. To address these challenges, the provision of empty spaces for rainwater harvesting has been a focus of attention as a potential solution to reduce the adverse impacts of these extreme phenomena. The objective of this study is to explore and propose effective strategies for optimizing the utilization of swamp lands for urban settlements in the Kertapati District of Palembang. The research methodology involves quantitative and qualitative analyses of hydrological data and land use on a property in Bukit Lama IB I, Palembang, South Sumatra, which has implemented the rainwater harvesting system. The hydrological data includes rainfall, roof catchment area, yard area, and rainwater accumulation rates. The results of the study show that the provision of empty spaces for rainwater harvesting can significantly reduce the risks of floods and droughts. When heavy rainfall occurs, this system can retain excess rainwater, thereby reducing surface runoff volume and slowing the flow toward rivers. Additionally, the harvested water can serve as a reserve to cope with drought during the dry season. The research also identifies several critical factors influencing the effectiveness of the rainwater harvesting system, including infrastructure design and surrounding land use. In this context, collaboration between the government, communities, and the private sector becomes crucial in implementing this system widely and sustainably. In conclusion, the provision of empty spaces for rainwater harvesting has proven to be an effective approach to reducing the risks of floods and droughts. Facing increasingly complex climate change, it is essential for communities, governments, and other stakeholders to adopt and implement this system as part of a comprehensive strategy to manage water resources sustainably and protect the environment.
