Study and Application of Salted Airtah Utilization Technology Under Seabed Surface with Incline Directional Submarine Groundwater Well can be a solution Provision of water resources on small islands. This technology is more environmentally friendly compared to the manufacture of vertical wells on the edge or offshore. Well Collar placement on the beach with bottom well that leads to the seabed will cause extracted water to be water under the sea. Water extraction from the bottom of the sea using the Incline Directional Well technology is the most appropriate method to be applied in small islands in Indonesia. This extraction water is water from the underwater which is in a hydrogeological system that is different from the hydrogeological system in the mainland so that the water supply used by the community will not be disturbed. In addition, this water does not contain marine biotic components such as zooplankton and phytolankton so that equilibrium The marine ecosystem is not disturbed. The community on Gili Trawangan island before the actions of PKM received a supply of clean water (freshwater) from Lombok Island and the results of seawater desalination carried out by the private sector. People buy water from desalination and shipments from Lombok for everyday use. Airtah from Gili Trawangan Island is salt water so it is only used to water the land. The scope of the implementation of community service activities includes literature studies, field data retrieval, and analysis and interpretation which is then used as a technical recommendation for the implementation of the implementation of Incline Directional Technology Submarine Groundwater Well.
Application of appropriate technology, the application of writing
Gili Trawangan in North Lombok Regency is one of the small islands that have difficulty clean water supply. The supply of clean water in Gili Trawangan is currently from Lombok Island and the results of the desalination run by the private sector. Seawater desalination itself is not a new technology because it has been widely used in other countries that also experience water difficulties. Desalination of sea water In general, it manages to answer the needs of clean water supply for the community, but many problems caused are well realized or not. The main problem that can occur is the damage to the marine ecosystem due to extraction carried out Bring sea biota such as phytoplankton and zooplankton from shallow sea waters. This condition causes the disruption of ecosystem equilibrium in shallow sea waters.
