ABSTRACT During the construction period there is often an incompatibility schedule between the planning and implementation in the field. Therefore, the need of doing control performance in order for the project to run in accordance with the contract time. To find out the performance of the project, can be used earned value method. The data that are required to analyze the performance using earned value are BCWP, BCWS, and ACWP. The control of construction project could be done by acceleration. Time Cost Trade Off method is used to obtain the most efficient and effective results. The purpose on this study is to evaluate a project that is experiencing delays in achievements. Based on the contract, if the contractor unable to finish the project in accordance with time that is given in the contract, the contractor will be charged with penalty of 0.1% of the agreed price. After being evaluated at week of 13th using earned value, it turns out that the project is experiencing delays where the project should be completed within 300 days and it turns out 314 days with the cost required to complete the project is IDR.16,139,554,490.00. In order for the project to be completed in accordance with the contract time, the writer does the acceleration by doing additional work time for 3 hours. By using time cost trade off method, the writer could determine the work to be accelerated by selecting from the lowest slope value on the critical path so that it could obtain the most efficient cost to complete the project on time. From the analysis result using time cost trade off, it is found that the acceleration resulting in the minimum total cost to complete the project on time is IDR.16,157,311,547.00. By using the additional working hours, this project could be completed with the most optimal time of 259 days with the total cost required is IDR.16,329,053,679.00. Keywords: earned value, control, time cost trade off

ABSTRACT Cost and time control is the heart of activities for contractors, because of this effort the company can earn profits and avoid risks, so that the survival of the company can be maintained and developed. At the implementation stage the dominant control element is carried out to find out whether time and costs deviate, according to or have exceeded the plan. After knowing the above conditions, it is necessary to project how much time and costs are needed again. The purpose of the schedule and cost projections in the implementation of the building construction project on a concrete bridge is to be able to find out how much time and costs are needed to complete the project, so that it is useful in making decisions. The results of the calculation show the estimated total project cost (Estimate All Cost - EAC) is obtained for = IDR3,671,279,379.50, from the planned IDR2,722,001,580.00. For the total project time estimate (Estimate All Schedule - EAS) is obtained = 112 days, taking the largest value, from the 91 day plan. Keywords: cost, EAC, EAS, time

ABSTRACT Indonesian government has built many dams in some areas and dams that have been built mostly earth dam. Earth dam becomes an option to be built because it was easier to obtain material to build the dam. Building process can be faster. Benel Dam in Melaya sub-district, Jembrana district, Bali province which had been evaluated was an earth dam that had been built in 2010. In order to provide benefits in the long time, the control of the seepage in the dam was needed so that safety can always be monitored. Measurements that were performed to determine the safety of the dam was measurement of the seepage discharge that occurs in the foundation. Therefore it is important to calculate the seepage discharge during the rainy season because in rainy season the water level in the upstream reaches the maximum position so it will cause maximum seepage in the foundation of the dam. The analysis was performed with SEEP/W and flow-net, with no cut off condition and with cut off. The result of the analysis that has been done, the seepage discharge in the dam’s foundation without cut-off for rainy season condition calculated with SEEP/W equal to 3.162 × 10-6 m3/sec and with cut-off obtained 2.077 × 10-6 m3/sec. While seepage discharge in the foundation of the dam without cut-off for rainy season conditions calculated with flow-net obtained 3.15 × 10-6 m3/sec and with a cut-off obtained 1.85 × 10-6m3/sec discharge. The results of this calculation show that the installation of cut off can reduce the amount of seepage. The seepage that occurs in the foundation of the dam was smaller than the allowed seepage that was 4.9206 m3/sec, so that the seepage discharge through the dam's foundation was safe for the dam. Key words: earth dam, flow-net, seepage discharge

ABSTRACT School safety zone (ZoSS) is a government program that began in 2006. The program aims to reduce the number of traffic accidents, especially school children. The use of ZoSS is still not optimal because there are still many road users passing ZoSS at high speed, school children have not used ZoSS facilities, as well as the surrounding community including teachers and parents who do not understand the existence of ZoSS. The approach taken is by observing the behavior of pedestrians, especially school children, the introductory behavior of school children, the behavior of drivers, the speed of vehicles passing on ZoSS, the volume of vehicles that are then analyzed and the performance of the road. The results of the study showed that the behavior of the crossers was 60.01% that meaning ZoSS was effective. The level of introductory behavior is 67.65% that meaning ZoSS was effective. The percentage of vehicles that follow ZoSS regulations is 32.58% that meaning ZoSS was less effective. The performance of the road segment in the ZoSS segment has a degree of saturation of 0.09 service level A. Keywords: driver, vehicle, ZoSS

ABSTRACT The construction phase is a stage that needs attention so that the main goal of producing a quality project can be achieved. In the construction phase, project managers should consider the positive and negative aspects that will occur in the next stage, the operational phase. The construction project is a job sector that has high risk compared to other sectors. The number of work accidents in Indonesia is quite high and continues to increase from previous years. the number of accidents in Indonesia continues to increase from 2007 to 2011. The number of work accidents in Indonesia in 2008 experienced the highest increase of 13.17%. While in 2011 the number of work accidents in Indonesia that the smallest increase is 0.79%. It indicates the risk of accidents in Indonesia is quite high. Cost of safety can be divided by other approaches that consist of cost prevention, inspection cost, and accident cost. If the security system is not valid or there is no safety program, usually the cost of prevention and inspection is not provided or available but small (less adequate), while the accident costs are great. prevention and inspection is sufficient, so as to reduce the cost of accidents to be small. Safety and work safety management system planning is a series of steps, hazard identification, risk assessment, risk control, and cost calculation of risk control. Based on this it becomes interesting to do an assessment of the estimated cost prevention (prevention cost) and inspection cost (K3) on the construction project. The results of the review on the construction project reviewed indicate that the costs required for prevention cost and inspection cost of work accidents amount to IDR 726,182,726.28 or 5.39% of the total contract value consisting of the cost of personal protective equipment amounting to IDR 585,780,486.28, the cost of occupational safety and health equipment of IDR 32,402,240.00 and the cost of personnel of occupational safety and health is IDR 108.000.000,00. Keywords: cost estimation, construction project, risk, work accident

ABSTRACT The activities of taking and picking up by parents of students often cause traffic congestion around the school. This happens almost every day, especially in the morning, when school starts and in the afternoon, when school hours are over. There is not an adequate parking space available at the school, so the introductory and pick-up people use the body of the road to park when delivering and picking up. To overcome this, transportation facilities are needed which can reduce the number of vehicles used to deliver and pick up school students. The information that you want to know from the survey on respondents is monthly family income, factors that are considered important in choosing the type of transport, the vehicle used by students, whether students go to school or alone, vehicle facilities for parents, travel time from home to school, desired service and departure schedule. The number of samples that have been set is a minimum number of samples from statistical calculations as respondents, where as respondents are parents of students. For this reason, questionnaires were distributed to the students, so that they were delivered to their parents. Based on the results of the questionnaire, the transport operation parameter data is obtained between the next pick-up, to get the number of passengers, service pattern, number of vehicles needed and the scheduled departure of transportation. The results of the analysis show that 74% of respondents want the first service pattern to be picked up on the main road at their respective address or residence. The estimated number of passengers to be served by the school student shuttle transportation in Denpasar City is 5148 people, with 214 vehicles needed. Vehicle departure schedule must be every 0.56 minutes starting at 06.50 WITA. Keywords: car pooling, operational, transportation

ABSTRACT The Government of Indonesia was committed to encouraging public-private partnership (PPP) schemes to address gaps in infrastructure development. But not all projects offered through the PPP scheme have a high degree of eligibility because the project is a long-term investment with a considerable degree of risk challenge. Efforts to improve the feasibility of investing in toll road PPP projects were made such as investment guarantees and incentives for the private sector. This study is a continuation of previous research that was an implementation of the incentive system in PPP project contract to increase investment feasibility. In this study, the authors want to obtain a general description of:(1) Existing condition of research location and land use based on Local Regulation around Bali Mandara Highway (Field Observation and Local Regulation), (2) To know the wishes of the people around Highway in a location that allows applied spatial use incentive system (Interview Method), (3) Assessing the spatial plan at the foot of the toll road regarding spatial use plan with guidance on incentives and density utilization of space on the highway (method of cropping the map). From the result of the research, it can be seen the general description of the people's desire to play a role in the utilization of space around the Nusa Dua toll, where the results of satellite image analysis and the spatial regulation on spatial planning allow the availability of land for spatial use activities around highway about 10 hectares. Keywords: highway, KPS, spatial, use of space
