    (wahyu sari yeni, 2018-09-19) Nurdin, Nurdin; Fakhri, Fakhri
    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 Kawasan Rawan Banjir Sungai Rokan Dalam Kabupaten Rokan Hulu Dan Kabupaten Rokan Hilir
    (wahyu sari yeni, 2019-01-03) Nurdin, Nurdin; Fakhri, Fakhri; Djuniati, Sri
    Rokan Hulu and Rokan Hilir Regencies are included in the Rokan and Kubu Watersheds. In the Rokan Hulu district there are several rivers, two of which are fairly large rivers, the Rokan Kanan River and the Rokan Kiri River. Rokan Hilir Regency is also passed by the Rokan Kanan River, which is a place of union with the Rokan Kiri River. Next to these large rivers there are many tributaries that all flow into the big river. At the edge and along the river, including tributaries, is often a flood subscription during the rainy season. The purpose of this study was to identify floodprone areas, in Rokan Hulu and Rokan Hilir Regencies so as to produce maps of flood-prone areas in Rokan Hulu and Rokan Hilir Regencies. To map flood-prone areas in Rokan Hulu and Rokan Hilir Regencies, it can be done with the help of remote sensing data based on Geographic Information Systems (GIS). From the analysis based on overlay maps of soil types, slope classes, land cover and rainfall with the scores and weightings given for each parameter that influence each other to identify the level of flood vulnerability in the study area, in the safe category 14,709.48 ha or 0.9%, Non-hazardous category 921,554.03 ha or 56.33%, the dangerous category is 496,025.36 ha or 30.32% and the category is very vulnerable for flood disaster 203,790.36 ha or 12.46% respectively from the study area

    Potensi Kayu Jenis Cepat Tumbuh (Fast Growing Species) Sebagai Material Alternatif Komponen Kapal Kayu Yang Berkelanjutan
    (2018-04-03) Fakhri, Fakhri; Suprayogi, Imam
    The supply of wood sourced from natural forests is diminishing, the scarcity of wood raw materials has implications for the decline of timber vessel business in quality and quantity. The limited supply of quality timber as raw material for ship components should be pursued by other alternatives in order that the traditional timber ship business can continue to operate sustainably. The objective of the study was to assess the potential of fast growing timber as an alternative feedstock for traditional wooden ship components. The method used is a survey identifying the potential utilization of rapidly growing local timber species for wooden ship components as well as the suitability of applied technology while maintaining the traditions and values of local wisdom. The results obtained that fastgrowing wood species is very potential to be utilized as an alternative material to overcome the scarcity of wood materials today. Appropriate technology is applied in the form of composite wood technology using coating technique using waterproof resin material (liquid resin Epoxy). Coating techniques will be able to protect wood components, improve wood resistance, and improve physical and mechanical properties of materials. the application of fast growing species and composite technology for wooden ship components can be applied based on the criteria of the Indonesian Bureau of Classification (BKI)
