Abstract

Cement production worldwide contributes at least a 9% increase in CO2 emissions. Industrial or agricultural waste can cause serious problems for the environment. One of the wastes that can be used as SCM from agricultural waste is sugar cane. This research was conducted to determine the content of chemical elements contained in bagasse ash which is suspected to have chemical content similarities with cement. This study uses an experimental method, with the type of pre-experiment research which has a one shot study case type research scheme. The results indicated that bagasse ash with a final combustion temperature of 600C had the highest silicon content compared to bagasse ash with a final firing temperature of 500C and 700C. The analysis results indicate that with a relatively high percentage of silicon, bagasse ash with a combustion temperature of 600C can be used as an additive or cement substitute.

Abstract

Penelitian ini bertujuan untuk menganalisis perbedaan hasil belajar pada mata kuliah Mekanika Teknik 1 menggunakan video pembelajaran berdasarkan gender. Populasi penelitian ini adalah mahasiswa Pendidikan Teknik Bangunan yang sedang mengambil mata kuliah Mekanika Teknik 1 pada semester ganjil tahun akademik 2023/2024 dengan sampel penelitian yang berjumlah 87 mahasiswa. Metode penelitian yang digunakan yaitu metode kuantitatif dengan teknik pengumpulan data menggunakan tes hasil belajar (pretest dan posttest). Analisis data yaitu dengan menghitung rata-rata hasil pretest dan posttest. Dari hasil analisis tersebut pada nilai rata-rata pretest laki-laki 84,26 dan perempuan 78,23. Sedangkan nilai rata-rata posttest yaitu untuk laki-laki 92,16 dan untuk perempuan 90,08. Maka, dari hasil tersebut dapat disimpulkan bahwa hasil belajar mahasiswa laki-laki lebih besar daripada mahasiswa perempuan pada mata kuliah Mekanika Teknik 1 Pendidikan Teknik Bangunan.

Abstract

The research aims to develop an E-Module for the subject of building maintenance management and the maintenance of architectural and structural components within the Building Engineering Education Major, Faculty of Engineering, Jakarta State University. The method used was Research and Development (R&D), adopting the Four-D (4D) development model, which consists of four stages define, design, development, and dissemination. The validation results from building maintenance experts yielded an average score of 77,33 classified as ‘Feasible’, with a validity score of 0,72 which categorized as 'Valid'. The media expert’s validation yielded an average score of 87,50 classified as 'Highly Feasible', with a validity score of 0,97 which categorized as 'Highly Valid'. The language expert’s validation yielded an average score of 88,00 also classified as 'Highly Feasible', with a validity score of 0,97 which categorized as 'Highly Valid'. In addition, the average pre-test score was 68 points, and the post-test score was 82 points. The N-Gain test results showed a score of 0,43 classified as "Effective" category. Based on the expert validation and the N-Gain test results, it can be concluded that this Building Maintenance E-Module is highly feasible and effective for use in building maintenance courses.
