    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.

    The main objective of the research is to conduct water conservation efforts through the application of rainwater harvesting technology as an alternative of city gardens water resource by utilizing flyover bodies as water catchment areas, where so far the rainwater that falls on the road pavement is not accommodated and only allowed to permeate or enter the drainage channel. The research approach method used is to implement the integrated of flyover bodies management with an environmental perspective (ecodrain) by accommodating, absorbing, flowing and maintaining excess water in order not to cause pool and danger to the environment using Rain Cycle 2 aid program with input data consist of: the effective catchment area (m2), the amount of annual daily rainfall (mm/year), drainage coefficient and water requirements (m3/day). The main results of the study stated that the results of the optimum reservoir size that could be constructed were approximately 385 m3, which was divided into seven reservoirs with a size of 55 m3 each with the dimensions of the reservoir (length, width and height of the tank) 16.22 m, 4 m and 1 m respectively. The rainwater harvesting produced contribute approximately 7.7% to 19% or equivalent to 9.24 m3 to 22.8 m3

    The purpose of this research is the application of rainwater harvesting technology as an alternative to fulfill the needs of clean water small islands in Riau province. Method of approach used for the research of the design of individual household scale in Concong Village Central Concong Sub District Indragiri Hilir as a water quantity containment effort to fulfill the needs of clean water communities in small islands. The main result is to refer to the results that there is a strong correlation between the determination of the number of tanks and the design financing of rain water tank storage harvested by the community. For the design of the tanks with a capacity of 2000 liters it takes two tanks at a cost of Rp 9.703.000, while for the design of the tanks with a capacity of 4000 liters, it takes four tanks at a cost of Rp 14.741.000 Keywords: design, tank storage, rainwater harvesting technology, small island, individual scale

    The main objective of the research is to establish a recommendation for forest and land rehabilitation activities (RHL) by planting forestry tree-based community participation in Rumbio Village indigenous Forest Kampar District. Method of approach for research using SWAT Model with data input model ArcSWAT such as digital map of Earth Indonesia scale 1:25,000, geological map of Sumatra scale 1:250,000, data of rain sourced from manual rainfall measuring instruments Ombrometer from the year 2013 – 2017, daily water level (TMA) data extracted from digital measuring instruments transferred through the Personal Digital Assistant (PDA) as the basis for the stage of the hydrograph, the discharge data using the rating curve equation, manual rainfall measuring equipment Ombrometer from the years 2013 – 2017 and the image of Google Earth Sub watershed Rumbio. The main results of the research proved that the management of Sub watershed Sei Tanduk in the indigenous forest of Rumbio village use SWAT Model approach by conducting forestry tree planting based on community participation using the best pattern system dry land agriculture to be used as an agroforestry to reduce sedimentation rate within two years from 2014 to 2016 by 47.80 ha/year through the activities of Land Forest Rehabilitation Program (RHL) by Watershed and Protection Forest Management Agency (BP-DASHL) Indragiri Rokan, Ministry of Environment and Forestry (KLHK) of the Republic of Indonesia
