Indonesia's coastal areas, including Semarang, are rich in resources but vulnerable to disasters that affect domestic water demand. Seawater intrusion and pollution threaten clean water quality, prompting communities to adopt adaptation strategies. Effective management of water resources and infrastructure is essential to ensure access to clean water and support adaptation efforts to environmental change. This study aims to (1) analyse the quality of water used by communities in areas affected by tidal floods, (2) examine the adaptation of coastal communities in meeting domestic water needs due to the impact of tidal floods, and (3) identify the role of stakeholders involved in supporting the adaptation of coastal communities to meet domestic water needs due to the impact of tidal floods in Tambak Lorok Village and Kemijen Village, Semarang City.
The method used was quantitative-qualitative with groundwater sample measurements and semi-structured interviews with 114 households as well as several relevant stakeholders, namely the Central Java Marine and Fisheries Agency, Semarang City Housing and Settlement Area Agency, Pemali Juana River Basin Agency (BBWS), PDAM Tirta Moedal, Bintari Foundation, Artesian Well Entrepreneurs, Tambak Lorok Joint Business Group (KUB), Kemijen Community (KOMJEN), and Department of Urban and Regional Planning, Faculty of Engineering, Diponegoro University.
The results showed that groundwater quality in Tambak Lorok and Kemijen villages is low enough to meet domestic needs. Of the seven artesian well samples tested, two were classified as brackish, while the others were in the transition category between fresh and brackish water. This reflects seawater intrusion, which is exacerbated by land subsidence due to groundwater exploitation and ongoing tidal flooding. In domestic water management, nine stakeholders were identified, with PDAM Tirta Moedal and the Housing and Settlement Area Office as key actors. Other stakeholders such as artesian well operators, BBWS Pemali Juana, Bintari Foundation, and local organizations also contribute in both technical and social contexts. However, cross-stakeholder coordination has not been optimal, and access to piped water services is still uneven. The community developed a mixed adaptation strategy by using gallon water for consumption, artesian wells for household use, and some utilized PDAM as an additional source. These strategies reflect an active response to existing structural limitations. This research confirms that community adaptation is not independent, but is strongly influenced by the quality of the physical environment and the effectiveness of water governance that involves many parties. Stronger collaboration between stakeholders is needed to ensure the sustainability of clean water supply in coastal areas affected by tidal floods.
