Abstract

Artificial coarse aggregates is an innovation to replace natural coarse aggregate. In this study, the material used for the preparation of coarse aggregate is industrial waste, namely Expanded Polystyrene (EPS). The purpose of using this s in addition to knowing the magnitude of the compressive strength, it is also necessary to know the amount of strain that occurs when the concrete receives a load. In addition to improving the performance of compressive strength, steel fibers are also added to the concrete mixture. The method used in this research is experimental and analyzed with a mathematical model to determine the theoretical modeling of the stress-strain curve. The experimental test results show that the use of steel fibers can increase the compressive strength of normal concrete while the effect of this artificial coarse aggregates can increase the strain value by 39% of normal concrete. The results of experimental and theoretical comparisons of mixture composition which are considered to be closest to the stress-strain curve of normal concrete are concrete with a mixture of 15% artificial coarse aggregates and concrete with a mixture of 15% artificial coarse aggregates and 0,75% steel fibers.

Abstract

Learning related to scheduling is done manually and with the help of Microsoft Excel applications. In its implementation, there are still some minor errors that cause changes in the total cost as a whole. The use of applications such as Microsoft Project is believed to be able to minimize the occurrence of this error because of the workflow control feature. The implementation of community service is expected to be able to increase knowledge and improve students' skills in preparing schedules appropriately and in accordance with applicable rules. From the questionnaire, it can be concluded that the students felt this training helped them to be more familiar with the scheduling function with Microsoft Project and helped to better understand the Construction Cost Estimation (EBK) learning.

Abstract

The role of measurement and mapping science in the construction sector is very important. The development of tools used for survey measurements and mapping is now in digital form. The application of land surveying knowledge can not only be obtained at universities but can also be obtained at Vocational High Schools (SMK) which have majors in the field of construction. To improve the quality of learning, competence and skills in the field of land surveying, training can be carried out. This training is a form of Community Service (PKM) which can be carried out by lecturers from the Civil Engineering Undergraduate Study Program. The partner in this PKM is SMK Negeri 1 Sidoarjo where training will be provided in measuring surveys and digital mapping. Adequate skills will be created if teaching staff and educational staff have adequate competence
