Abstract

Construction and its concrete scaffolding is a temporary construction (construction support in concrete construction), due to the cost required is quite large, approximately 1/3 of the total cost of the concrete construction, it is based on the analysis of unit price work (SNI 03-7394-2008), therefore it needs to be examined in order to reduce the cost of its construction and for the cost efficiency in the construction of storey buildings. This research conducted assessments of the selection of scaffold materials for the manufacture of concrete construction, the objective is to select the best type of scaffold material thus it would be able to reduce the cost of the buildings construction. By using the method of Analytic Hierarchy Process (AHP), the assessment was conducted on the three alternative types of scaffold materials of concrete, these materials were the bamboo, the wood, and the iron / pipe galvasnis (scaffolding). The result of the calculation by the alternative assesment, is that the higher rank is the scaffolding which is 0,531, while the bamboois in the second with the total score 0,301 and the wood is the lowest with the total score 0,168. It can be assumed that the result of this research on the basis of five criteria, namely: the cost; the strenght and the durability;the effectiveness of the instalation and dismantling; the security and the safety work, as well as its impact on the invironment that the scaffolding is the best alternative chioce of the materials.

Abstract

Soil with a high shrinkage value flowers, water affects the physical and mechanical behavior of soil (Das, 1994). Expansive clays generally have less favorable properties such as dry density ( d) low maximum, capacity / California Bearing Ratio (CBR) is low, low shear strength, and flowers shrinkage (Swelling) high. Nature is what causes the often damaged pavement repair is often done even if the pavement structure. Condition of roads in the Spring Mulyo also experienced the same thing that is fast though damage is often done to improve the road surface layer. To overcome these problems one way or the method used is to improve the quality of the original soil (stabilization). The study was conducted to find out more about the influence of lime and sand stabilization material to the amount of soil bearing capacity and CBR. Laboratory testing includes testing the soil compaction and CBR. The percentage increase varied from 5% sand, 10%, and 15%. While the addition of lime percentage varies from 5%, 10% and 15%. In this study indicates that the addition of lime and sand to clay soil has a tendency to increase the density of the soil, soil CBR value well in conditions without a bath or a bath. The optimum condition occurs in a mixture of clay with 10% limestone and 15% sand with a CBR value 9.08% with the soaked and the CBR value of 20.06% with unsoaked

Abstract

Sanrego river located in the village Sanrego, District Kahu, Bone regency, South Sulawesi Province. This river has an important role to people's lives. In addition to functioning whether as a container supporting agriculture as well as one of the tourist place. But lately, frequently flooding during the rainy season. This happens due to a buildup of sediment in the irrigation channels at certain points. Namely on the primary channel, secondary channel, and tertiary. It has an impact on the performance of waterworks itself. This research aims to determine the amount of sediment (sediment-rate) that occurs on the channel point to review and to provide an overview and explanation of the value of the correlation coefficient (R) is based on the relationship between sediment discharge (QS) with water discharge (QW). This Research conducted by measuring directly on location by measuring the water level in each cross section of the channel and water sampling to test concentrations in the sediment. The results of research showed that the rate of sediment on the Primary Channel of Sanrego was 4,253 kg/day, Secondary Channel of Batu-Batu was 0,0593 kg/day, Tertiary Channel of Palakka 1 was 0,0403 kg/day, Palakka Tertiary Channel 2 is 0,0155 kg/day, Tertiary Channel of Batu-Batu 1 was 0,000578 kg/day, Tertiary Channel of Batu-Batu 2 was 0,0199 kg/day, with an average correlation coefficient (R) of 0,960, it shows the relationship between sediment discharge (QS) with water discharge (QW) has a positive direct perfect connection, which is between 0,6 < R <1,0. While on the secondary channel Palakka of 1,218 kg/day, with a correlation coefficient (R) of 0,210, this shows the relationship of sediment discharge (QS) and water discharge (QW) has a direct positive relationship is weak, that is between 0 < R < 0,6.

Abstract

Each of land use is going to give effect to erosion , land damages and run off. Land use policy and it’s conservation can be ditermined from the prediction result of erosion and the permitted erosion rate that is determined. Peanute is one of agrybisnis comodities that have a higher economic value among some kinds of plants else. It is possible enough to be developed in Indonesia. Sustainable development demands to each land user has to take care of conservation principles in order to getting sustainable use and it’s pruductivity kept. Land use policy and it’s conservation can be determined from result of predicted erosion rate and soil loss tolerance. Generally, some factors influence to the erosion rate are precipitation, topography, vegetation and human factor. To anticipate development of peanute plant, it needs to studying about practice factor of concervation and factor of vegetation management. The objective of research is to analyze value of CP factor of USLE equation, that is combination of crop management factor (C) for peanut and practice conservation factor (P) especially nicols terrace. The research is conducted with field measurement approach method by model of plots and by specifications : at field land with 10 % slope, length of land slope 20 m, type of soil Dark Brown Mediterranean (Alfisol/Inceptisol), for about 3 months and amount of precipitation rate about 257.72 mm/month. The research has given a result that CP factor of USLE equation for nicols terrace that combined to vegetation of peanut (CP value for nicols terrace + peanute) is about 0,32.
