Abstract

Denpasar City has an index of population increase worth 2.07% every year. It is feared that this will become a new problem in terms of environmental sustainability, such as the overexploitation of groundwater to meet the community’s water needs. This study aims to support the sustainability of water resources by using Rainwater Harvesting (RWH) as a form of green building planning. The method used in this study is a quantitative descriptive method, which is an analysis method carried out to calculate and describe the scale of RWH in the focus of the system’s effectiveness with the study location in the campus environment of the Ngurah Rai University Denpasar. The results of the study stated that 11 roofs of capture buildings produced rainwater of 1,783,350 litres/year. Another analysis said that this RWH method could cover all water needs, especially water used for flushing toilets. It is stated that the total water deficit of -703,734 litres/year can be subsidized from the entire remaining rainwater harvesting water of 879,624 litres/year. In addition, rainwater harvesting also plays a role as a form of effort to maintain the conservation of water resources and the application of green buildings that are energy efficient and environmentally friendly.

Abstract

Bali's administrative center, Renon Village, faces an increased risk of flooding due to land cover change. Conservation is needed to reduce this risk by improving water infiltration capacity. Infiltration wells are a solution to increase infiltration capacity. The Tri Hita Karana concept approach, especially Palemahan, in Balinese culture is adopted to implement infiltration well conservation with the support of GIS technology and by flood regulations and infiltration wells. The analysis showed that with a land area of 100 m2, the dimensions of the infiltration well were obtained in diameter of 1 m, and a depth of 2 m with a total of 2 pieces could absorb 2.46 m3 of rainwater. The application of infiltration wells in the study area can reduce the discharge and volume of flood peaks of 2 years, 5 years, 10 years, 25 years, 50 years, 100 years, and 200-year flood peaks, effectively reducing from 8.61% to 31.24%. This research supports the planning of sustainable drainage with a Low Impact Development approach. In addition, the construction of infiltration wells also contributes to preserving water conservation and applying green buildings that are environmentally friendly and energy efficient.

Abstract

Groundwater is a valuable resource for meeting the daily needs of humans, which continues to increase along with population growth. Therefore, it is essential to maintain groundwater properly. Groundwater management can be carried out comprehensively in groundwater basins, including determining groundwater recharge areas. This study aims to determine the location of groundwater recharge to conserve groundwater in Denpasar City to create groundwater sustainability. The geospatial analysis uses a weighting and scoring approach (Overlay Weighted Sum) to determine the groundwater recharge area. Retrieval data in the field by observing geological conditions and measuring the depth of the phreatic surface in Denpasar City. The determination of recharge and discharge areas was analyzed using the geospatial method using the ArcGIS 10.8 application using Interpolation Inverse Distance Weighted (IDW). The five parameters used in this scoring assessment are lithology, rainfall, soil cover type, slope, and phreatic surface depth. The highest score obtained from the weighting of the scoring is 46, while the lowest score is 36. The recharge area is found in the weighted value of 41-46, which is in the northern region of Denpasar City. The discharge area is located at a weight value of 36-41 in the southern area of Denpasar City.

Abstract

Urbanization and climate change are expected to exacerbate and introduce uncertainty in future flood characteristics. The city of Denpasar often experiences flooding due to rapid population growth and changes in land use. One form of flood mitigation that can be implemented is infiltration wells. This research aims to design infiltration wells as an environmental conservation effort by evaluating the characteristics of the watershed and the depth of groundwater. This research will also examine lithological aspects and use geographic information systems (GIS) to increase effectiveness in planning. The research results show that the construction of infiltration wells at the research location is effective in reducing flood volume, with reductions varying between 19.86% in South Denpasar and 59.58% in North Denpasar, East Denpasar and West Denpasar. Infiltration wells not only reduce the risk of flooding but also play an important role in preserving the environment according to the Tri Hita Karana concept. By integrating these sustainable practices into spatial planning, water resource management can be enhanced, fostering a healthy environment for future generations.

Abstract

Massive conversion of agricultural land into built-up land occurred in South Denpasar District. These changes impacted the decline in rice production by 5.5% in 2023 and a decrease in the performance of the irrigation network. This study employs GIS to assess the efficacy of irrigation networks to enhance sustainable agriculture, community food security, and irrigation and subak network systems in South Denpasar. This study used spatial analysis to create an irrigation network performance map. Data analysis interprets primary data based on field observation to assess the irrigation network's physical condition. The irrigation network is divided into four levels: good, slightly damaged, medium damaged, and badly damaged. The study indicated that Subak Sesetan disintegrated since it was thought to have turned into a village. The land conversion reduced the 292.593 Ha of subak (Kerdung, Cuculan, Kepaon, and Sesetan) to 186.314 Ha, or 36.32%. The length of irrigation canals was 16.901 Km, with good conditions along 16.67 Km or 98.61%, slightly damaged conditions along 0.051 Km or 0.3%, and moderately damaged conditions along 0.1842 Km or 1.09%. This research should help South Denpasar District stakeholders decide on land-use change strategies and rehabilitation or irrigation network development priorities.
