Abstract

Research on the Effect of Mixed Addition of Cement And rice husk ash Against and Stabilization on Roads Budi Utomo I aims to determine the effect of Addition of Cement And rice husk ash and to finding the optimal mix levels of Addition of Cement And rice husk for land Stabilization. Tests conducted at the Laboratory of Engineering, University of Bengkulu and the types of tests as follows: natural water content, specific gravity, sieve analysis, atterberg limits, standard proctor,and CBR (California Bearing Ratio) laboratories. Based on laboratory testing, native land in Jalan Budi Utomo I was clay with high plasticity After testing the original soil coupled with a mixture of cement and rice husk ash obtained optimum results occur at levels of 12 % of the 4%, 8%, dan 12% variations. The following test results with a mixture of cement and rice husk ash with levels 12 % : on the CBR laboratories testing provide CBR value increase up to 148.42 % of the original soil CBR by weight of the dry contents increased up to 3.846 % of the dry weight of the contents of the original soil. The optimum moisture content decreased to 13.754 % of the original soil optimum water content, whereas soil plasticity index dropped to 50.084 % of the original soil plasticity index, and the specific gravity value of the land increased to 1.923 % of theoriginal soil. Improved stability of the soil caused by cement and rice husk ash containing silica elements where this element has a very large contribution as an adhesive and can harden by reaction with water so as to increase the strength of the soil stabilization.

Abstract

In 2000 to 2009, at least two big earthquakes happened in Bengkulu. The first earthquake occurred in June 4 th, 2000 and the second one occurred in September 12, 2007. Two big earthquakes not only triggered the extensive damage of structures and infrastructures, but also triggered the attributed disaster such as liquefaction. Liquefaction occurred in Bengkulu were signed by sand boiling and lateral spreading in minimum to maximum scale in coastal area, particularly in Lempuing Sub-district. Soil condition in Lempuing Sub-District is dominated by sandy soil with shallow water table depth. Rely on the experience of earthquake and liquefaction disaster in the past, a preliminary evaluation of soil liquefaction in Lempuing Sub Districthad been conducted. The evaluation was performed to define the relationship between peak ground acceleration coefficient and relative density for variation of D of soil sample. This evaluation can be used to estimate the preliminary liquefaction potential before continue more detail analysis.

Abstract

This research about analysis of erosion and land critical level on watershed (DAS) Padang Guci of Kaur Regency is based on few watershed in Bengkulu Province that allegedly has decreased function, which on of it is watershed (DAS) Padang Guci. Watershed (DAS) is an ecosystem which main elements consist of natural resources, water, and vegetation, and also human resources as its user. Several performance indicators of watershed (DAS) that can bemeasured is the index of land cover, forest land cover condition, erosion hazard index, and land management index. Watershed (DAS) Padang Guci has land area about 52689,2 ha. This research using data analysis and maps with Geographic Information System (GIS) in order to get the result of studies that determine the performance of its watershed. The result of the analysis using Geographic Information System (GIS) in the watershed (DAS) Padang Guci is60% of the total area, erosion occur with a very light level. Critical Potential land dominates the cultivation area is 65,41%, while 59,73% critical potential dominates the protected area outside the protected forest. Sediment delivery ratio that obtained was 0,024. The decrease of region function well in cultivation area. It conclude that for the performance of the watershed (DAS) Padang Guci based on land use indicators overall categorized still safe. Keywords : Watershed (DAS), Critical Level’s Area, Erosion, GIS

Abstract

The advantages of concrete are : high in compressive strength, durable, easy to cast. The weakness of concrete is low in tensile. Palm fiber is the natural fiber which is high in tensile. This research aims to know the tensile strength of concrete with palm fiber addition. The diameter of the cylinder is 15 cm and 30 cm height. There are 4 variation in palm fiber addition i.e 2,5%, 5%, 7,5% and 10%. The concrete mix design is based on SK SNI-T-15-1990-03 with water cement ratio 0,5 and slump range between 6-10 cm. The curing process in based on SNI03-2493-2011. The test was done at the age of 28 days based on SNI 03-2491-2002. The highest value of tensile strength test is with 10% addition of palm fiber (2,667 MPa) which is 24,09% higher than normal concrete. This research shows, the palm fiber addition increase the tensile strength of concrete.
