STUDI KARAKTERISTIK HUJAN PEMICU LONGSORAN PADA RUAS JALAN TAWAELI-TOBOLI SULAWESI TENGAH
Get PDFLandslide is one of the most types of slope movements of soil\rock often occur in Indonesia and resulting in damages such as in agriculture land, highways, structures and even casualties. From the researches landslides often take place on the rainy season,as well as when the rain is falling or after the rain stopped. This research will be done in two phases. First phase is a numerical modeling to simulate and predict slope hidrological behavior in respon to rainfall. The rainfalls applied for modeling are high and low intensity that are £ 70 mm/hour and 20 mm/day respectively some hours until days. The rainfall modeling results is used as the data for next phase that is slope stability analysis. Slope stability will be analiyzed at the initial condition, when raining and after the rain stopped. This research results the decreased of slope stability caused by the rain depends on the intensity and duration of the rain. The research obtains that the rain intensity of 70 mm/hour is the most potential cause to trigg the landslide than goes of 20 mm/day, 30 mm/hour and 50 mm/hou

Get PDFPerception data of assessment of contractors’ competency is necessary to be collected from any parties who involve in construction projects in order to improve contractor selection system, not only in the stage of prequalification phase, but also in the stage of tender phase or in the stage of a selection of the winning contractor. To obtain the answer of contractors’ perception in terms of the most to the least important factors of the assessment of contractors competency, a structure questionnaire survey was conducted in Palu, where the sample came from a part of small contractors in Palu. Technical and managerial strength and compliance with regulations factors are the highest rank, while financial strength is the lowest rank. Moreover, positive correlations of the techncial and managerial strength exhibit statistically significant with other factors
IMPLEMENTASI ALGORITMA PRIM PADA JARINGAN DISTRIBUSI LISTRIK PRIMER DENGAN MENGGUNAKAN PROGRAM BERBASIS GIS
Get PDFOptimization problem is the demanding problem for optimum solutions. The optimum (best) solution is asolution with minimum values, or maximum among a set of possible alternative solutions. In electricaldistribution network, problem of demanding achievement of optimum condition of system operationalperformance is essential. One of the factors necessary to consider in the designing of the primary electricaldistribution network is cost. Cost is closely related to length of cable used. It highlights the importance ofcalculating the minimum length of cable required in a network. The cable should be not only with as minimalas possible in length, but also regulated for better arrangement.Actually, in regulating the cable installation, longer path is more frequently selected. One of the ways ofachieving optimization condition is to use algorithm to determine a minimum spanning tree of the primaryelectrical distribution network system. In this study, the algorithm used is Prim’s algorithm.The research was conducted by designing a graph model of primary electrical distribution network inappropriate with the data obtained. Based on the graph, each was weighted for distance or length of networkcable by using the ArcView GIS 3.3. The data were then calculated and simulated by using computer to gaina minimum spanning tree of the primary electrical distribution network using the Prim’s algorith
