Dr. I Ketut Ariantana, ST, M.Si., successfully defended his dissertation entitled "Management Strategy for Sustainable Drinking Water Supply Systems on Nusa Penida Island" in front of the Promoters, Copromoters, Refuters, and Academic Invitations who were present at the Doctoral Promotion today and received academic achievement with honors. The paper is a report on the results of research and analysis in 2022, which later became a requirement for obtaining a doctoral degree in Environmental Science. Nusa Penida Island, which is a karst island, requires a management strategy in the provision of drinking water. The existing Drinking Water Supply System (SPAM) is considered ineffective in terms of maintenance, operational management, and the level of drinking water service. In the context of sustainability, an integrated evaluation and analysis of conservation, economic, and social aspects is carried out so as to produce an effective and sustainable SPAM management strategy.

 

As a novelty in this research, among others, the source of water in Nusa Penida Island is a mixed spring of meteoric water with limestone subsurface water; the recharge area is a unit of the Nusa Penida Island area; and a government cooperation scheme with the private sector (business entities) is needed in the management and development of sustainable SPAM.

Prof. Ir. Made Sudiana Mahendra, M.App.Sc., Ph.D., as promoter, congratulated and wished him success in obtaining a doctoral degree. "With this, the promise at the beginning of entering PDIL has been fulfilled, namely by taking full time and then fulfilling all academic tasks, so it is proven that today you have completed the academic process on time. I congratulate you and wish you success in obtaining this doctoral degree", he said. (bmp)
