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.
