Abstract:
This paper discusses the problem of how to determine the main priority of the strategy to meet
clean water needs that can be applied to small islands, especially on Merbau Island using the
Analytic Hierarchy Process (AHP) method. 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.
