Abstract

Construction work can cause Work Accident Risk, therefore the implementation of construction work is required to implement an occupational safety and health (K3) management system at the work site. However, the IAIN Ambon Library and Laboratory Rehabilitation and Renovation project was not implemented. So this study aims to obtain the Dominant Occupational Accident Risk, the causal factors and how to respond to these causal factors. The method used in this study is a semi-quantitative analysis method combined with the domino method. Semi Quantitative Analysis in the form of distributing questionnaires containing a scale of 'likelihood' and 'consequency' values and processed with SPSS, then analyzed with a Risk Matrix while the domino method is used to identify factors causing work accidents. The results obtained: 1. There are 8 Dominant risks (1) Workers are exposed to noise from iron cutting machines, (2) Workers' heads are exposed to wood impact during baking installation, (3) Workers' eyes are exposed to Splashing of Concrete Mixture, (4) Workers' breathing is disturbed due to ceramic cutting dust, (5) Workers are exposed to noise from ceramic cutting tools, (6) Workers' eyes are exposed to splashes from liquid paint, (7) Workers' breathing is disturbed due to ACP cutting dust, (8) Workers are exposed to noise from ACP cutting tools. 2. Factors causing work accidents (1)Lock of control/Management (2) Basic Cause of accident (3) Immediate cause/symptoms (4) Incident (5)Loss. 3.Response to factors causing work accidents, namely (1) Risk Reduction (2) Risk Transfer.

Abstract

In this study which focuses on the four aspects studied, where for the main reason of being interested in aspects of human resources related to competence, motivation, loyalty and work discipline are general aspects that unwittingly exist in the worker himself and the worker is one of the triggers for the success of a construction project. These four aspects have an impact on the performance of workers, because the work does not reach the deadline. Thus, it gives rise to the desire to explore more deeply the reasons for work that does not reach the target and by increasing work time (overtime), because in the construction project of Masela Block Integrated Laboratory Supporting Buliding of Pattimura University has so many workers in their fields, it is felt that there is a slight delay due to the number of workers with the work itself. The study was conducted by distributing questionnaires for the distribution of questionnaires, the data analysis technique used was SPSS 26 software. Data analysis starts from validity test, reliability test, classical assumption test, namely normality test, descriptive analysis, multiple linear regression analysis and Relative Importance Index (RII) From the results of the analysis carried out on human resources on aspects of worker performance, multiple linear regression analysis shows that human resources have a positive and significant effect on worker performance, and the most dominant influence on the results of the RII calculation is the work discipline aspect, namely 0.820 or 82%, the second is the aspect, namely competency 0.411 or 41%, then the third aspect of motivational is 0.394 or 39% and the last is the loyalty aspect, namely 0.300 or 30%.

Abstract

The construction of the Waiheru Ambon Hajj Embarkment Transit Building was intended to be the object of this study because it was based on the background that occurred in the project, namely delays. Based on secondary data obtained from the project, the Budget Plan (RAB) and Time Schedule are used as project’s duration and normal costs of the project. Then the time cost trade off method is applied which aims to be able to reduce the duration and find out the total cost needed so that the project can reach the planned time target so as not to experience delays. Dimyati, H (2014) explained that there are two reasons why acceleration of construction of construction projects is carried out. First, because off the desire of the owner so that the project can be completed before the deadline for project completion. Second, because in the implementation of the project there is a delay in time or progress, the acceleration must be carried out.This is where the importance of a plan that must be prepared carefully so that cosis that will have an impact on acceleration the project can be controlled properly. Time acceleration in this project, using the Time Cost Trade Off  Method with the principle of increasing overtime working hours. After accelerating with the addition of 3 hours, it could save time by 0.11% where the project cost is reduced by around 0.003%. Meanwhile, the addition of 2 hours could save time by 0.10% where the project cost is also reduced by around 0.003%. While the optimal duration and optimal costs were known in the alternative addition of 3 hours of overtime obtained 94 working days at a cost of IDR 27,388,709,338.20. Meanwhile, in addition to 2 hours of overtime, 95 working days were obtained at a cost of IDR 27,388,026,130.23.

Abstract

Construction  projects are one of the of the activities where the results of the work are influenced by the productivity of the workforce. Activities in construction projects are interrelated, so that if one activity is late it will hinder other activities in the field. Likewis, construction activities are complex work and require more attention in their implementation. The aim of  this research is to obtain what factors influence labor productivity and determine the presentation of the influence of independent variables on labor productivity in the classroom building (RKB) construction project of madrasah ibtidaiyah negeri 5 maluku tengah. The analysis method used in the research this is with the help of the SPSS version 26 program. In the  new classroom building (RKB) Construction project of madrasah ibtidaiyah negeri 5 maluku tengah there are several factor that influence labor productivity including labor, material, weather and environmental factors and the presentation of the influence of independent variables on labor productivity, which is 88.1% and the remaining 11.9% was influenced by other variables not tested in this study.

Abstract

There are several aspects of project implementation management, such as implementation plans, schedules, and others. The emergence of problems in the implementation management aspect hurts project implementation. Then the alternatives that are usually used to support the acceleration of activities is to increase working hours so that it has an impact on the total project cost. The Madrasah Ibtidaiyah Negeri 5 Maluku Tengah New Classroom Construction Project was chosen for the research study because it experienced delays. The CPM (critical path method) is used to analyze the project implementation time to obtain critical work that has no leeway days to be accelerated. The optimal time and cost are obtained from the Crash Program using the Crashing method by adding working hours to each accelerated critical work. From the acceleration, the cost slope value is obtained. the purpose of this research is to determine what work is critical in the project and also get the results of analyzing the calculation of time and cost of work after being accelerated. The result showed that the total normal project cost budget of Rp 2,891,000,000 with an implementation duration of 120 days, in conditions after crashing with an alternative of adding working hours for two hours obtained a cost of Rp 2,943,185,364 greater than the total project cost budget under normal conditions and a reduction in duration to 110 days or faster than the normal duration. The total cost slope value obtained was Rp 64,231,234.
