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.Item Analisis Dampak Fenomena El Nino Terhadap Ketersediaan Air Tanah Di Bima, Ntb Pada Tahun 2015(wahyu sari yeni, 2019-01-03) Simanjuntak, Juni Tika; Azka, Mukhamad Adib; Dzikiro, Tesla KadarWater is the most important thing in our life. Therefore, the lack of water (deficit) will be very harmful to all living creatures and it is almost certain that water deficit areas will experience drought. Water deficit can be caused by El Nino. In 2015, El Nino is listed at an intermediate level moving towards a strong level. Bima region, West Nusa Tenggara is one of the affected areas of El Nino. Therefore, it is interesting to study the availability of soil mosture in the area. The availability of soil mosture can be measured by a water balance analysis. The study was conducted using rainfall data and temperature from meteorology station Sultan Muhammad Salahuddin. Rainfall and temperature data are averaged over the El Nino period in 2015 to make land balance calculations yielding surplus and deficit data. The supporting data in atmospheric dynamics analysis using sea surface temperature data were processed using GRADS, wind data, and Southern Osilation Index data obtained from BOM (Bureau Of Meteorology, Australia). The method used is the method of calculating the water balance of Thorthwaite Mather , while the method of calculating the nature of rain using the method of classification of rain properties with normal criteria (85% - 115%), below normal (<85%) and above normal (> 115%) then presented in graphic. This condition shows that El Nino has a big influence on availability of soil mosture in Bima, West Nusa Tenggara. The most deficit of soil mosture occured in August.Item Analisis Deforestasi Hutan Mangrove Di Kota Dumai, Riau(wahyu sari yeni, 2019-01-03) Mulyadi, Aras; Efriyeldi, Efriyeldi; Ilahi, IlhamThe era of regional autonomy has triggered the development of Dumai City towards a better direction. As a coastal area in Riau Province, it is estimated that it will threaten one of the potential coastal ecosystems, Dumai City is a mangrove forest. This study aims to analyze deforestation of mangrove ecosystems in Dumai City, Riau. Analysis of deforestation using ArcGIS and NDVI clasic version 4.5 software for imagery in 2005, 2010 and 2015. The causes of deforestation were carried out through interviews with the community. In 2005 there was 649.64 ha of mangrove area, but 46.79% of deforestation had occurred in the Dumai City mangrove forest so that in 2010 the remaining area was 345.06 ha. The main factors driving the deforestation of mangrove forests in Dumai City stem from the conversion of land into industrial estates, the construction of ports, roads, plantations, agriculture, and settlements. In addition, it is also caused by the use of mangrove wood for household needs, charcoal wood and building materials. The utilization of mangrove wood can be proven from the magnitude of the percentage of logged-over stumps which is more dominant (amounting to 67.32%) compared to natural dead stumpsItem Analisis Efisiensi Produksi Padi Sawah Di Provinsi Riau(wahyu sari yeni, 2018-09-19) Bakce, DjaimiThis study aimed to determine the application of techniques and the efficiency level of rice farming in Riau Province. Descriptive analysis and Data Envelopment Analysis was used to analyze the efficiency level. The main findings of the study indicate that the application of rice farming technique in Riau Province has not been done properly. The using of maintenance and cultivation technique have not fully implemented the Six Precise system, i.e the exact number, place, type, price, quality, and time. Based on the results of the analysis using DEA: Firstly, most rice farming is technically inefficient because of the land using, seed, fertilizer, pesticide and labor which still exceeds the required capacity. Secondly, almost all rice farmers are inefficiently allocative because of the high ratio of input prices and output prices. Third, rice farming is almost entirely economically inefficient. The policies that can be applied by the government is to subsidize production factors, especially seeds, fertilizers and pesticides. It is necessary to apply the policy of giving bigger price incentive to the farmers on every kilogram of rice produced. Besides, the policy of agricultural insurance to rice farmers need to be applied so that farmers remain motivated to continue to conduct rice farming activities.Item Analisis Kandungan Natrium Dan Kadmium Serta Tingkat Kematangan Tanah Gambut Bekas Terbakar Berulang(wahyu sari yeni, 2019-01-09) Hanifah, T.

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.Item Analisis Potensi Lokal Provinsi Riau Dalam Mendukung Penguatan Edukasi Lingkungan Di Perguruan Tinggi(wahyu sari yeni, 2019-01-09) Haryanto, Rudy; Suwondo, Suwondo; Wulandari, SriStrengthening environmental management can be done through environmental education in universities.

Fakta Dan Potensi Das Musi(wahyu sari yeni, 2018-09-19) Ulya, Nur Arifatul; Waluyo, Efendi Agus; Kunarso, Adi; Syabana, Tubagus Angga AnugrahThe National Medium Term Development Plan (NMTDP) 2015-2019 states that the Musi watershed is one of the priority watersheds to be restored. Given the coverage of the Musi watershed covering 3 provinces (South Sumatra, Bengkulu and Jambi), 14 districts and 4 municipalities, the utilization and management of the Musi watershed require synergy between stakeholders, including local governments. This study aims to explore the potential of payments of environmental services of Musi watershed using case study approach and data analysis generally refers to an institutional development analysis developed by Ostrom (2008). The payments of environmental services by downstream beneficiaries can make conservation activities become more attractive option for stakeholders in upstream Musi watershed, even encouraging them to adopt this mechanism. Payments for environmental services should be clear, more than an additional benefit to stakeholders regarding alternative land use. Although the reward of environmental services is not designed specifically to improve the welfare of the community but in the implementation of this mechanism can play a role in improving the welfare of the community in the upper Musi watershed. Payments for environmental services approach to communities that maintain and manage upstream watersheds can play a role in improving community welfare.Item Beban Emisi Gas Buang Kendaraan Bermotor Berdasarkan Jarak Tempuh Dan Jumlah Kendaraan Pada Persimpangan Pasar Pagi Arengka Pekanbaru(wahyu sari yeni, 2019-01-09) Darimi, Darimi; Siregar, Yusni Ikhwan; Anita, SofiaBackground and Purpose: Air pollution will make the city environment unhealthy and can interfere with human health, therefore air pollution must be strived so as not to increase. One way to reduce air pollution in urban areas is to reduce greenhouse gas emissions and build Green Open Space (RTH). Therefore the purpose of this study is to calculate the exhaust emissions of motor vehicles in the city of Pekanbaru based on the distance traveled and the fuel used. Materials and Methods: Air pollution at a certain level can be a combination of one or more pollutants, either in the form of solids, liquids or incoming gases dispersed into the air and then spread to the surrounding environment. Further analysis in this study is to analyze environmental factors related to community environmental health and research methods is a quantitative method that is trueexperiment, the equation used is the emission load equation of the exhaust gas. Result: Some compounds produced from complete combustion such as non-toxic CO2, have recently become a concern of people. CO2 compounds are actually naturally occurring components in the air. Therefore CO2 previously did not keep the order of air pollution which is more than normal attention due to excessive use of fuel every year, so that in this study shows an increase in CO2 with increasing number of vehicles and mileage. Conclusion: Exhaust emissions are strongly influenced by the distance traveled and the number of vehicles, but there are other factors associated with increased gas emissions, namely congestion, so that technological advances in reducing the rate of increase in exhaust emissions are no longer functioning. Other factors that need to be taken into consideration are the number of vehicles, vehicle age, vehicle maintenance, vehicle speed, type of fuel, amount of fuel, and engine capacity that can affect vehicle exhaust emissions on the intersection of the morning market.Item Beban Pencemaran Limbah Domestik Sungai Parit 13 Kecamatan Tembilahan Kabupaten Indragiri Hilir(wahyu sari yeni, 2019-01-09) Harahap, Syaiful RamadhanParit River 13 is one of the rivers that crosses Tembilahan subdistrict with a relatively high population density.
