This study began with a survey of 100 family heads by distributing questionnaires. The questionnaire contains questions relating to personal data, and data about the components of rainwater harvesting. The opinions of experts were asked in this matter to determine the values considered by experts in determining strategies for meeting clean water needs on Merbau Island. Then an analysis is carried out using the AHP program. The results showed that the fulfillment of recommended water requirements on Merbau Island was to maximize household scale rainwater harvesting (RWH). Maximizing rainwater harvests on a household scale is a top priority with the support of the availability of adequate clean water facilities and infrastructure. In relation to clean water facilities and infrastructure, it is expected to use a rainwater harvesting technology system, therefore the criteria of technology have the highest value, but in the field it is difficult to implement by the community so government support is needed in realizing it. Government support is highly expected because 44% of the island's population Merbau is a poor person who naturally prioritizes basic needs rather than providing good and right rainwater harvesting facilities and infrastructure.enAnalytic Hierarchy Process (AHP)Small IslandClean WaterRainwater HarvestingArticle
