    Kampar District is traversed by two large rivers and several small rivers, including Kampar River which is ± 413.5 km long with an average depth of 7.7 m, and an average width of 143 m. Referring to Central Statistics Agency Kampar Regency (2015), Kampar residents numbered 703,005 people with a growth of 2.57% that exceeded the national population growth in 2010 of 1.49%. The Kampar Kanan River has a much larger flood impact than Kampar Kiri River because the majority of the population lives along the banks of the Kampar Kanan River. Areas that are always targeted need to be mapped in the form of flood vulnerability maps within Kampar regency. To map areas susceptible to flooding in Kampar District can be done using remote sensing data based on Geographic Information System (GIS). Analysis of the overlay map results as an indicator of flooding in 4 flood vulnerability classes in Kampar regency. Overlaid maps consist of Rainfall Map, Slope Map, Land Use Map and Geological Map, which resulted in the widest area in Kampar District in the prone category of 459,977.89 ha or 42.86% of the district area. The second sequence is in the non-vulnerable category 236,082.39 ha or 22.00%. While the order of the 3rd area is in very vulnerable category that is 219.279.54 ha or 20.43%, and the smallest area is in the safe category of 157,835.01 ha or 14.71% of Kampar Regency area.

    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.

    (wahyu sari yeni, 2019-01-03) Nurdin, Nurdin; Suprayogi, Imam; Sujatmoko, Bambang; Suwondo, Suwondo; Mustofa, Riyadi; Anggoro, Hafiz Catur
    Galugur Kapur IX Sub district watershed is one of the upper watersheds in the Kotopanjang hydropower reservoir which has the potential to trigger a reservoir sedimentation rate increasement due to land clearing for plantations so that it will speed up the filling of dead bin of reservoir significantly which will have an impact on the reduction of the planned service life of the reservoir. The research objective is to analyze the potential for erosion in the Galugur watershed using Geographic Information System (GIS) as an information of a watershed management policy. The research approach method for erosion estimation is the Universal Soil Loss Equation (USLE) method. The USLE method is influenced by four factors: rain erosivity factor (R), soil erodibility factor (K), downhill length and slope factor (LS), and land utilization factor (CP). These erosion estimation factors are then converted into four thematic maps, namely rain erosivity map (R), soil erodibility map (K), downhill slope and length map (LS), land cover and management map (CP). All thematic maps that have been generated are overlaid and will produce an erosion distribution map. The main results of the study proved that erosion that occurred in the Galugur watershed based on GIS was dominated by low category erosion approximately 43% of the total area of 5787,123 ha. Confirmed by the results of research that states that the Galugur watershed erosion product will blend with the water flow from the upstream to the reservoir, so that the sediment in the reservoirs will occur in large scale quantities. The reservoir sedimentations have the potential to be a threat to the reduction in the service life of the Kotopanjang hydropower reservoir which is designed to operate for 100 years.
