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

Rendahnya hasil belajar peserta didik pada elemen Perhitungan Statika Bangunan menjadi fokus utama dalam penelitian ini. Hal tersebut dipengaruhi oleh metode pembelajaran yang kurang melibatkan siswa secara aktif, sehingga peserta didik masih kesulitan dalam memahami konsep tumpuan pada struktur bangunan. Untuk mengatasinya diterapkan model pembelajaran Problem Based Learning (PBL) yang dirancang mampu dalam melibatkan peserta didik terhadap pemecahan masalah nyata sebagai sarana membangun pemahaman. Penelitian ini menggunakan pendekatan kuantitatif dengan desain penelitian yaitu Post-test-Only Control Design, melibatkan dua kelas X Desain Pemodelan dan Informasi Bangunan (DPIB) di SMK Negeri 1 Sidoarjo. Kelas eksperimen sebanyak 38 siswa menggunakan model pembelajaran Problem Based Learning (PBL), sedangkan kelas kontrol sebanyak 37 siswa menggunakan pembelajaran Discovery Learning. Data dikumpulkan melalui observasi, angket, dan tes hasil belajar. Hasil menunjukkan keterlaksanaan di kelas eksperimen sangat baik (guru: 95,5 %; peserta didik:88,6%) dan respon peserta didik sangat positif (82%). Berdasarkan hasil uji-t, diperoleh nilai t hitung = 3,35 yang lebih besar dari t tabel = 1,99, yang menunjukkan perbedaan hasil belajar yang signifikan. Dengan demikian, penggunaan model pembelajaran Problem Based Learning (PBL) terbukti efektif dalam meningkatkan keterlibatan dan hasil belajar peserta didik.
