Abstract

Debris flow is the flow of mixture of water (from rain or other) with a high concentration of sediments slide down through the high slopes. Often, this flow carry large rocks and tree trunks, sliding down at high speed with great destructive force capabilities against anything in its path such as building houses or other facilities that threaten human life. Debris flow is not directly associated with volcanic eruptions, but can occur in volcanic regions and non-volcanic. Kanako 2D version 2.043 is a simulation software that is used as a tool to verify the effects of erosion control by sabo dam in the process of sediment transport during the debris flow. By using the tool, it can be estimated the occurrence of debris flows on the slopes of Mount Sago with simulation. Keyword : Debris flow, Kanako 2D, Sabo dam

Abstract

The influence of rising sea water on tidal land has always been a very common problem in the process of tidal land use as farmland. Network system of water began to be developed, namely the open channel system comes with water as formatter building floodgates, but it hasn't been able to made a solution of the problem increases in sea water to agricultural areas. The importance of knowing the description of the behavior of the flow on the draft water building make this research needs to be done. The use of open channels that come with building a sluice water regulator combined with water weirs are expected to hamper the rising tide if applied on tidal land use as farmland. The purpose of this research is to know the influence of variations of the opening hole sluice and sluice hole cross-section shape of the flow behavior change through the door water combined with weirs in open channel water in the form of discharge coefficient value (Cd). This research was conducted at the Laboraturium University of Hidroteknik Riau using a flume which features open channel water balance door and threshold. The results of this research show that building floodgates open channel on the threshold and are able to withstand the tide of different variations of the opening hole. The value of the coefficient of discharge (Cd) 10 mm hole openings variations between 0.60-0.70, 20 mm hole openings variations i.e. 0.30-0.45 and a 30 mm hole openings variations i.e. 0.25-0.40, These results are obtained from multiple upstream water faces tall test channel.Keywords : open flow, the floodgates, the coefficient of discharge.

Abstract

Berth B (The pour liquid berth) is one of the berth which has a higher activity in Dumai Harbour. Berth B handling cargo activities dominated by CPO with the amount up to 5 million tons each year and come increasing every year. The increasing amount of CPO, need a project to know the value of visiting ships and the value of BOR in short term. Project value is required to evaluate performance of the port so in the future the berth still being capable to manage activities of cargo handling. Based on results of analysis, the value of BOR in short time projection until 2021 is 82.90%. To fulfill The Standard Of Managing Director Of Marine in 2011, the value of BOR was 70% it could be did by adding the lenghth of berth and increase discharge of the pump. The short time projection in 2021 the Berth should be lengthnened formerly 800 meters become 961 meters. Another solution that could be done without adding the length of berth is increased the discharge of pump. The capacity of pump formerly 200 tons/hour, by increased the discharge into 250 ton/hour the value of a BOR become 62.18%Keywords: harbour, berth, cargo handling of CPO, BOR, projection

Abstract

Drought is a problem that occurs in every year whose timing can not be known certainty. Therefore, it is necessary to do drought index analysis to determine the level of drought in order to become early warning of drought. There are several methods that can be done to determine the level of drought of a region, one of them is the SPI (Standardized Precipitation Index) method. The SPI method is a suitable method used to calculate meteorological drought. The SPI method uses rainfall data as its input data. TRMM rainfall data is satellite rainfall data that can be used for calculation of SPI value. The research location is Bukit Batu District, Bengkalis Regency, Riau Province which has been divided into 23 grid with 0.10 x 0.10 grid width. From the results of SPI calculations displayed in the form of graphs can be concluded that each grid has the same trendline. The SPI values that have been obtained are then correlated with the number of hotspots. From 23 grid of Bukit Batu Subdistrict, BB7 grid is the grid with the highest number of hotspots in 2014.Keyword: Drought Index, SPI, TRMM, Hotspot

Abstract

Lima Puluh Kota is one of the regency in West Sumatera Province that prone to landslide, particularly when the rainfall intensity is high. Therefore, the research is conducted to determine the location that prone to landslide in Lima Puluh Kota regency in order to prevent the risk that potentially leads to disaster. The model that was applied to determine the prone landslide location is Indeks Storie, which would be treated in Geographic Information System’s program. Before that overlay process has been done, which was overlaying some of parameter maps (map of slope, map of soil types, map of rainfall, and map of land use) and marked the score in eachcriteria from the parameter maps. Based on the level classification analysis of Arifin S, et al (2006) Lima Puluh Kota regency is on the very low, low, and medium level of prone to landslide. This condition is contradicting with the actual fact. Based on level classification analysis of Nugroho, J.A, et al (2009) there are areas in Lima Puluh Kota that have very low, low, medium, high, very high level of prone to landslide which close to the actual fact. From the analysis in this map, the prone to landslide level in Pangkalan Koto Baru is very high, Sarilamak and surrounding areas have medium and high prone to landslide level, Harau subdistrict has high prone to landslide level, Gunung Omeh subdistrict has medium prone to landslide level.Keywords: SIG, Prone to landslide
