Abstract

This study uses an experimental method to investigate the behavior of concrete blocks coated with fiber paint, focusing on their shear and flexural strength, ductility, stiffness, and energy dissipation to enhance their mechanical performance. The fiber paint coatings used in this study were applied in different thicknesses, namely 1 mm, 2 mm, and 3 mm. The results show that a 3 mm coating provided the highest improvement, with shear and flexural strengths increasing by 47.36% and 66.06%, respectively. Flexural ductility improved by up to 32%, while stiffness increased by 12% in flexure and 13% in shear. Energy dissipation also showed significant enhancement; total flexural energy increased from 1.38 kNmm to 10.76 kNmm at 3 mm, and shear energy dissipation reached 50.72 kNmm at 3 mm. These results confirm that fiber paint can enhance the shear and flexural strength, ductility, stiffness, and energy dissipation of concrete blocks. This study introduces fiber paint as a practical reinforcement method for concrete block materials, offering a simple, easy-to-apply, and cost-effective alternative that improves both mechanical and aesthetic performance.

Abstract

Penelitian ini bertujuan mengkaji tentang pengembangan modul analisis kurikulum pendidikan teknologi meliputi uji validitas, uji praktikalitas dan uji efektifitas. Penelitian ini termasuk dalam penelitian Research and Development (R&D). Model yang dipakai dalam penelitian ini menggunakan prinsip ADDIE, metode pengumpulan data melalui angket dan tes hasil belajar, analisis data diolah menggunakan pendekatan kuantitatif dari penerapan modul dan dideskripksikan melalui pendekatan kualititatif untuk meyimpulkan hasil penelitian, subjek penelitian terdiri dari dosen dan mahasiswa. Hasil penelitian yang dilakukan terhadap pengembangan modul berbasis android memenuhi kelayakan, ditinjau dari aspek validitas, praktikalitas dan efektifitas. Hasil analisis aspek validitas pengembangan modul dari validator ahli materi adalah 92,98% dengan kriteria sangat valid, sedangkan dari validator ahli media adalah 78,57%, aspek praktikalitas pengembangan modul dari respon dosen pengampu skor persentase rata-rata 98,95% dan respon mahasiswa skor persentase rata-rata 87,76% dengan kriteria sangat praktis. Aspek efektifitas pengembangan modul dilihat dari tes kognitif hasil pembelajaran mahasiswa berupa pre-test dan post-test dengan menggunakan rumus gain score. Hasil tes pengetahuan pada 24 mahasiswa dan mendapatkan nilai skor rata-rata yang baik sebesar 74,29%, sehingga mencapai kriteria sangat tinggi. Kesimpulan bahwa pengembangan modul pembelajaran berbasis android ini mampu menarik perhatian mahasiswa dan membuat mahasiswa paham terhadap materi serta membuat mahasiswa mampu bekerjasama dalam berkelompok.
