Abstract

The construction of the new classroom construction project at MTSN 6 Malteng 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. After accelerating with the addition of 3 hours, it could save time by 8,33% where the project cost is reduced by around 0,21%. Meanwhile, the addition of 2 hours could save time by 6,67% where the project cost is also reduced by around 0,17%. While the optimal duration and optimal costs were known in the alternative addition of 3 hours of overtime obtained 110 working days for IDR 2,992,374,365.55. Meanwhile, in addition to 2 hours of overtime, 112 working days were obtained for IDR 2,993,479,584.03.

Abstract

In the world of construction services, labor productivity is one of the determining factors for the success of a development project. It measures the success or failure of a construction project in achieving its objectives. One way to increase worker productivity comes from worker attitudes by increasing worker commitment, satisfaction, and responsibility for work. Therefore, in efforts to analyze labor productivity, variables that might influence the level of productivity must be considered. This research was conducted to find out what factors influence labor productivity and to determine the influence of labor characteristic factors on worker productivity. The research was carried out by observing the productivity level of 15 workers and accompanied by filling out a questionnaire. From the data collection results, both productivity data and questionnaires were processed using the SPSS (Statistical Package for Social Science) version 26 computer program. Based on the results of the analysis of factors that influence productivity, including skill diversity (x1). task identity (x2) variable task significance (x3). Based on the results of hypothesis testing, skill diversity has a positive effect on productivity with a positive T count value of 2.630 > 2.160. Task identification has a positive effect on productivity with a calculated T value of 2.435 > 2.160. Task significance hurts work productivity with a calculated T value of -2.384 < -2.160. Based on the R square test, it can be seen that the characteristics of the workforce consisting of the variables skill diversity, task identity, and task significance simultaneously influence productivity with a multiple determination coefficient values of 84%, and the remaining 8.4% is influenced by other variables not included in this research.

Abstract

Bricks are a building material that has long been known and used by people in both rural and urban areas and has the same function, namely as a construction material. Bricks are used for civil engineering applications such as walls and residential buildings, fences and also channels. Bricks are made from clay which are made using a simple mold made of wood. After being molded, the bricks are dried in the sun to dry. Once dry, the bricks are arranged neatly and burned at a fairly high fire temperature. This burning process can cause the bricks to become hard. This research was carried out to determine the quality of bricks in two villages, namely Hatu village and Laha village using physical and mechanical properties testing on printed brick samples. Based on the results of testing the physical properties in Hatu village, it was found that the specific gravity was 1.596, the bulk density was 14.7 gr, the porosity was 37.8% and in the Laha village the specific gravity was 1.811, 13.6 gr and 42.4%. Meanwhile, the mechanical test results for the bottom sample in Hatu village were 27.31 kg/cm2 and the bottom sample was 40.10 kg/cm2 and the results in the bottom sample village were 19.16 kg/cm2 and the results for the top sample were 18.02 kg/cm2.

Abstract

Brickstone is a material for building house walls made from cement, aggregate, and water. Brick stones are widely used in house construction as a substitute for bricks to speed up construction. Recently, many additional materials have been used as alternatives to reduce high construction costs. One way is using household materials, namely ash from burning, because they are easy to obtain. Therefore, the idea of ​​making bricks using a mixture of lime and burning ash is expected to produce bricks with better characteristics, with fine compressive strength by SNI. In this research, bricks were made with dimensions of 25 cm long, 13 cm wide, and 10 cm high. With a composition of 200 grams of lime, 1500 grams of ash, 1000 grams of sand, and 2000 grams of water. With a total of 3 test objects, the age of the test objects to be tested is 28 days. The average compressive strength test results of ash bricks for the 3 test objects were 8.7 kg/cm2. Following SNI 03-0349-1989 concerning physical requirements for bricks, the average compressive strength value for class IV is 25 kg/cm2. Based on these requirements, ash bricks mixed with lime do not meet SNI.

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.

Abstract

In project implementation, there is often project completion that is not under planning both in terms of cost and time, so to overcome it requires good project management in the form of cost control and good implementation time in order to help the implementation as planned. in the MIN 5 Central Maluku New Classroom Construction Project located in Tulehu Village, Salahutu District, Central Maluku Regency which has a budget of Rp. 2,891,000,000.00 with a planned implementation time of 120 calendar days from June to October 2022 but the realization of the project is late and completed in 161 calendar days. To overcome these problems, the author uses the Result Value method.The Earned Value method is a control method used to control project costs and time in an integrated manner. Project time or schedule control is a process of monitoring the status of project activities to determine the progress or progress of the project. While project cost control is a process of monitoring the status of project costs to find out project costs at the time of the project.From the results of the analysis in the 3rd month, the value of the cost variance (CV) shows the number (-), which means that the cost of project expenses is greater than the budget. While the value (SV) of the schedule variant shows (-), which means the work is carried out later than the work. However, the evaluation in the 4th month seen from the value of the cost variance (CV) shows a number (+), which means that the cost of expenses is smaller than the budget (Rp.2,891,000,000,00) with the actual cost (ACWP) of the 4th month of (Rp.1,775,028,092.00). The profit obtained by the contractor amounted to (Rp.174,661,809). And the time required to complete the project is 5.53 months.
