Abstract

This study aims to analyze the effect of using seashells as a partial replacement for fine aggregates on the compressive strength of concrete and slump value. The research methods include literature review, laboratory experiments following SNI and ASTM standards, mix design calculations, and compressive strength and slump testing on normal concrete samples (BN) and concrete with seashell mixtures (BK). The results indicate that using seashells affects the compressive strength of concrete. Normal concrete achieved a compressive strength of 220.7 Kg/cm², while concrete with a 2.5% seashell mixture achieved a compressive strength of 223.7 Kg/cm², meeting the compressive strength standard for K-200 grade. However, concrete with a 5% seashell mixture only reached a compressive strength of 132.6 Kg/cm², failing to meet the standard for normal concrete. For slump testing, the addition of seashells influenced the slump values. Normal concrete had a slump value of 9 cm, while concrete with 2.5% and 5% seashell mixtures yielded slump values of 8 cm and 10.8 cm, respectively. This study concludes that seashells are effective as a partial replacement for fine aggregates at a 2.5% proportion to improve the compressive strength of concrete, while a 5% proportion does not produce results comparable to normal concrete standards.

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

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.
