    ANALISIS KUALITAS SUMBER-SUMBER AIR UNTUK PENGELOLAAN PEMENUHAN KEBUTUHAN AIR BERSIH DI PULAU KECIL (STUDI KASUS: PULAU MERBAU)
    (2019-11) Joleha, Imam Suprayogi; Bochari, Bochari; Nurdin, Nurdin
    This research was conducted with the aim to find out the quality of water from several raw water sources that will be used as clean water sources. Raw water sources that do not meet clean water quality standards will be used as a basis for taking alternative water treatment methods so that the quality of clean water is obtained in accordance with the standards. The selection of water sources and treatment methods is also based on the socio-economic conditions of the Merbau Island community. The results of testing several sources of raw water obtained that the overall quality of rainwater meets clean water standards only the degree of acidity (pH) of rainwater (5.6) is still below the neutral pH standard. Whereas water sources from groundwater have several elements / substances that do not meet clean water standards including zinc (Zn) dissolved, dissolved iron (Fe) and KMnO4. Surface water in the Merbau Island region is categorized as brackish / peat water and has characteristics that do not meet clean water quality including color, turbidity, DHL, pH and organic matter (KMnO4) as well as iron and manganese. From the test results it is proposed that water treatment for rainwater sources is a slow sand filtratin system. Water Treatment with an Up-flow Slow Sand Filtration System and down-flow Slow Sand Filtration System from a grond water Source. As for water that comes from surface water is also categorized as peat water which has the characteristics of color, turbidity, organic matter and high cations and has a low pH, so it is recommended to use a conventional system with several stages of the process including oxidation, adsorption process, coagulation - flocculation processes and electrocoagulation processes. By looking at the current socio-economic conditions of the Merbau Island community, it is proposed that rainwater sources use a treatment system or without treatment, rain water is suitable for use as a source of clean water.

    PENERAPAN TEKNOLOGI PENYEDIAAN AIR BERSIH BAGI MASYARAKAT DENGAN PEMANFAATAN PEMANENAN AIR HUJAN SKALA INDIVIDUAL RUMAH TANGGA DI PULAU-PULAU KECIL
    (2019-11) Suprayogi, Imam; Joleha, Joleha; Bochari, Bochari; Nurdin, Nurdin
    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
