Abstract

Purpose: Seawater intrusion in North Kuta District, Badung Regency, has become a serious threat due to excessive groundwater exploitation, groundwater subsidence, and tourism activities. Previous research showed a decline in groundwater quality and expansion of seawater intrusion. This study aims to map the distribution of seawater intrusion in 2024 and predict its spread until 2029 in order to provide mitigation recommendations. Research methods: The study used the Audio Magnetotelluric (ADMT) and geoelectric methods at 15 track points, as well as groundwater quality tests in 32 wells with TDS, DHL, chloride, pH, salinity, and hardness parameters. The data were analyzed using the Surfer program for mapping the distribution of intrusion, and the prediction of the spread rate was calculated through regression analysis based on historical data. Findings: Distribution of Intrusion 2024 low-moderate category occurred in Canggu and Tibubeneng Villages (resistivity 4.5–15 ohm.m; TDS 700–10,000 mg/L), while the high-level category was identified in Kerobokan Kelod Village (resistivity <4.5 ohm.m; TDS 10,000–20,000 mg/L) with a stretch of 1,200 meters on the coast and 700 meters inland. In 2029, intrusion is predicted to spread inland at a rate of 35–56 meters/year, especially in Kerobokan Kelod, due to increased chloride and decreased water quality. Implication: Seawater intrusion has the potential to cause health problems (e.g. urolithiasis) and threaten the sustainability of water resources. Therefore, it is necessary to limit groundwater extraction, strengthen the PDAM network, and conserve aquifers.

Abstract

Badung Regency is highly dependent on tourism, while the agricultural sector based on the subak system faces land conversion pressure and declining economic contribution. Integrating agriculture and tourism through subak-based agrotourism development is a strategic approach to sustain agrarian landscapes while improving community welfare. This study aimed to identify the potential of subak areas for agrotourism development and analyze the participation of krama subak (subak members) in Mengwi and North Kuta Districts, Badung Regency. A participatory–spatial approach was applied by combining Participatory Rural Appraisal (PRA) and Analysis of Tourism Operation Areas and Natural Attraction Objects (ADO-DTWA) across 83 subak. The results showed that all subak were categorized as moderately to highly potential, with key strengths in agro-cultural landscape attractiveness, environmental conditions, water availability, and accessibility. Werdhi Putra Sedana and Tegan subak were identified as highly potential due to their diverse attractions, basic facilities, and strong community support. Krama subak demonstrated high participation in cultural preservation, landscape management, educational attractions, and tourism services, although limitations in capacity, facilities, and marketing remain constraints. Spatially, Mengwi functions as the core subak-based agrotourism area, while North Kuta acts as a transitional agrarian–tourism gateway. Sustainable development requires strengthening community capacity, improving facilities, and implementing community-based governance models.
