Abstract

Labor’s productivity is one of the success factors in construction project. The optimal labor’s performances can be measured using the productivities coefficient of the workers. The coefficient of productivities known as BOW analysis is further updated into SNI analysis. However, the value of labor’s coefficient productivity may be different at each location depending on their performances. For example the steel work labor’s who perform their work either outside or inside the project site. Therefore, this research takes some work sites on the steel workshop and the storey building project. The purpose of this study is to know the coefficient of labor’s productivity of steel working on the workshop and the storey building project. Then, the results of the observation is compare with the benchmarks that presents at this moment, which is BOW and SNI so can be obtained the optimum coefficient values of productivity. The results revealed that the coefficient’s value of steel labor productivity for foreman in workshop, building project, BOW, SNI are 0.0179, 0.0089, 0.00 and 0.004 respectively. The value of coefficient productivity for chief worker in workshop, building project, BOW, SNI are 0.00, 0.0089, 0.255 and 0.007 respectively. In the building project, the foreman and the chief worker do not only do steel working but also doing other types of job so it assumed that both of them are doing only 60% in steel working. The value of coefficient productivity for Vulcan in workshop, building project, BOW, SNI are 0.0359, 0.0592, 0.675 and 0.07 respectively. The value of coefficient productivity for assistant worker in workshop, building project, BOW, SNI are 0.0887, 0.0726, 0.675 and 0.07 respectively. Based on the coefficient value, it can be concluded that the order value of the optimum coefficient productivity of the worker is in the  workshop, building projects, SNI and BOW.

Abstract

Setiabudi street, Semarang, is access road to the southern area of Semarang, that is often used in addition to highway. This road connects the Semarang to Tembalang and Banyumanik, also connect to the southern area of Central Java. Some segments have gradient road more than 8% and critical gradient oad is different with RSNI Geometrik Jalan Perkotaan 2004. Setiabudi street that have gradient road > 8% cause acceleration of the vehicle decrease. It also causes traffic accident. Based on the issues conducted research to review the relationships of gradient road and critical gradient length to road safety. The survey method use spot speed and traffic counting. Secondary data is geometric of the Setiabudi street, traffic accident and annual daily traffic. Analytical methods to determine the relationship between gradient road and critical gradient road use regression method and descriptive analysis. The relationship of gradient road and critical gradient length to road safety is indicated by polynomial regression model Y = 174 222 - 3.827E-013X - 13166.052X2 + 3.995E-011X3 (R square= 0.998). The correlation value indicate the relationship gradient road and road safety is close. Some segments with gradient road and critical gradient length is high not necessarily cause a high number of accidents. The simulation results can be concluded the reduction of the degree of saturation cause risk of accident is reduced.

Abstract

The increasing number of private vehicles using in Semarang causes a high traffic volume in some primary roadways of the city. It can be seen from the use of official cars vehicle / personal that originally totaled 34,000 vehicles in 2007 to 44,600 vehicles in 2009 (Badan Pusat Statistik Kota Semarang, 2009). The presence of mass public transportation Bus Rapid Transit, which is Trans Semarang, is considered not able to overcome such problem yet. The value of the load factor both BRT corridor I and II were only 20-30%. (Based on research Chairunnisa R, Yenni N, 2010 and Ilham H. Rasyid, Aldila Bachtawar., 2013). The aim of this research is to evaluate public transportation’s performance and to figure out the policy of public transportation that is suitable for the economic condition, and demand from citizens of the city of Semarang. The methods used are analyzing previous research data about public transportation, especially BRT Trans Semarang, and processing primary data in the form of interview survey to citizens. The survey is done in three sub-districts: Ngaliyan, Pedurungan, and Banyumanik. The aspects that are reviewed through the side of effectiveness and efficiency of public transportation are headway, frequency, public transport fares, security, safety, and comfort. According to the result of the research, it is identified that more than 50% of citizens prefer using private vehicles, because the public transportation had not satisfy yet. Therefore, the effort of improving and developing provided public transportation is needed. In this case, the region is divided into two sections journey, namely urban and suburban areas. In the urban areas, can be done by revamping the BRT transport system, the provision of special BRT lane, and the provision of feeder that fits the needs of society. Whereas in suburban areas, public transportation is needed for high speed travel time savings, in addition to reducing the occurrence of traffic congestion on the main roads of the city.

Abstract

Along with increasing amount of using container as distribution of goods, Central Java Provincial Government with PT. KAI and PT. Pelindo III planned reactivation of railway to distribute freight container. This meant that distribution of container on highway can be reduced, so the density and number of traffic accidents also the use of fuel can be reduced. The study aims to identify the traffic of containers, determine the origin-destination, cargo and container tonnage, predict future container needs, and design the railway construction. Methods of analysis were GDP data processing using shift share analysis and container demand prediction using regression analysis. Railway construction planning refers to PD no.10/1986 and other applicable guidelines. The result showed that container traffic at Semarang Container Terminal is constantly increasing. In 2013, the amount of movement of export-import reached 524.139TEUs, divided into 3 regions of origin/destination, western (24.43%), southern (53.23%) and eastern (22.34%). From the results of shift share analysis and regression, it is predicted that 30years later, container demand will reach 47.254.973Ton/Year. With such loads, the railroad is classified into first class, with maximum speed 60km/h, using R.54 types with 250m length, connected by bolts and welding, fastened by double elastic Pandrol type, and using prestressed concrete pads. Sub-ballast thickness needed is 20cm. Railway crossing is accomodated using wessel no.10.

Abstract

Semarang city is very strategic because it is located in the middle of the north track of Java, connecting East Java and West Java. Annually vehicles across the city of Semarang increases, this was the trigger traffic jams especially on road segment and intersection of the north - west Semarang city. The growth of Gross Regional Domestic Product at Constant Prices 2000 Central Java 6 percent represents that the rate of growth in daily traffic average intersection has increased in the next 5 years. Figures show the feasibility of the service with the highest degree of saturation (DS), the condition on the road DS < 0.75 and at the intersection of DS < 0.85. The results of the analysis of primary data obtained from the field survey in September until Oktober 2013 showed the value of DS on existing roads still eligible, while the value of DS intersections are not eligible. Basic steps of traffic jams problem solving,namely the optimization of intersections with signal timing, intersection geometry settings and traffic management. After these steps are considered not provide significant changes in the value of DS, the last step is planning the construction of northern outer ringroad, or toll road.With the construction of new roads, intersection capacity will be increased with increasing growth rate LHR Semarang city in the years to come.

Abstract

Construction sector in Indonesia, especially for road construction projects are progressing very rapidly in recent years. Indonesia is intensively implementing the road construction project, from new road construction, road maintenance and repairs. Road construction sector in Indonesia is mostly using the conventional contract system, with a lump sum or unit price. In this conventional contract service user must fully bear the risks associated with the quality of work that is to be maintained. It required an innovative method in order to contract the service user and the service provider can be better off, for example with the system performance based contracting (PBC). This study will analyze the differences between the PBC system and conventional system by comparing the life cycle project, project coordination line, the construction, the maintenance period, and the budget plan contract. The research method used was a descriptive analytical methods and data collection through direct field observations and interviews with project case studies Construction Project Semarang-Bawen Road with PBC and Construction Project Semarang-Solo Highway. From the results, the fact that the PBC has a single stage system that is not present in the conventional contract there is system maintenance services. At  the PBC system imposed fines ranging from construction period while the conventional system of fines awarded the contract if the contract or is unable to complete the construction work by the duration of time that has been given. At the PBC system there is not planning consultant contracts while the conventional system, there are consultants planning consultant. At the PBC system maintenance is faster than the conventional contract system maintenance. The budget plan contract at the PBC system is higher than the conventional contract system’s budget plan contract.
