Abstract

This study aims to identify the most optimal material composition in achieving the best combination of hardness and wear. The experimental method was conducted using a special test bed designed to test the mechanical properties of various material compositions. The material specimens used were weighed before and after the test to calculate the wear rate by observing the change in specimen mass. The results showed that the 50:50 material composition performed significantly better than the 60:40 composition in terms of hardness and wear properties. These findings suggest that the 50:50 composition may be a superior choice in various applications where a combination of strength and wear resistance is required, such as in the manufacturing industry, materials engineering, or the automotive sector. This research provides valuable insights into material selection that can improve the performance and durability of the final product.

Abstract

This research focuses on the wear analysis of heavy vehicle gearbox systems, with particular emphasis on the case study of operational load fluctuations as a factor influencing wear rates. Heavy vehicles play a central role in various industries, and gearboxes are key components that affect operational performance and reliability. In this study, we collected operational data from various heavy vehicles operating under various conditions and environments. Through rigorous statistical analysis, we were able to identify a significant relationship between operational load fluctuations and gearbox wear rates. The results indicate that an increase in operational load fluctuations can proportionally increase the wear rate. These results have important implications in the development of smarter and more efficient maintenance strategies for heavy vehicles, which can reduce unexpected maintenance costs and increase gearbox service life. In addition, this study also confirmed that the basic assumptions in regression analysis, such as normality of residuals, homoscedasticity, and independence of residuals, were well met. This validates the results of the regression analysis and provides a solid basis for decision-making in the context of heavy vehicle maintenance. Recommendations for further research development include more detailed data collection, the use of more advanced analysis methods, and the application of sensor and IoT technologies for real-time monitoring. With continued research in this area, we can advance our understanding of wear on heavy vehicle gearboxes and support the development of smarter maintenance strategies in the heavy transportation industry.

Abstract

Desa Paya Geli merupakan sebuah desa yang memiliki kepala keluarga 4.923 dengan jumlah penduduk 21.265 jiwa pada tahun 2018. Desa ini terletak di kecamatan Sunggal Kabupaten Deli Serdang dan memiliki populasi ternak yang cukup tinggi yaitu 278 ekor kambing. Permasalahan yang sedang dialami Mitra meliputi masalah dari segi Produksi dan Pemasaran, diantaranya adalah a) Kebersihan kandang kambing yang usang membuat kotoran kambing berserakan, b) Pemerasan susu kambing yang masih manual dengan menggunakan tangan mengakibatkan kebersihan pada susu hasil perasan kurang higienis, c) Varian rasa susunya masih original, d) Tampilan susu dalam kemasan plastik masih terlihat biasa dan belum modern, e) Pengemasan yang kurang menarik masih menggunakan kantong plastik untuk tempat susu, f) Tidak adanya promosi yang dilakukan Mitra, sehingga publik tidak mengetahui akan keberadaan susu Kambing Etawa. Solusi dari permasalahan adalah dengan memberikan alat pemerah puting susu, memberikan pelatihan dan pendampingan dalam pembuatan varian rasa susu kambing etawa dengan menambahkan rasa buah, dan penjualan online menggunakan beberapa platform e-comerce yang ada di Indonesia, serta membantu dalam pengurusan perizinan produk susu kambing etawa.

Abstract

Pentingnya perlindungan dan pemeliharaan motor listrik di lingkungan industri yang rentan terhadap beban lebih atau overloading. Overloading terjadi ketika motor listrik dioperasikan dengan beban melebihi kapasitas normal, berpotensi menyebabkan kerusakan dan risiko kebakaran. Sebuah program pelatihan teknisi industri di PT. Prima Multi Peralatan diinisiasi untuk mengajarkan implementasi dan pemeliharaan sistem proteksi motor listrik. Metode dalam pelatihan meliputi sesi teori dan praktik, membekali peserta dengan pengetahuan tentang konsep dasar proteksi, komponen sistem proteksi, dan cara mengatur serta mengimplementasikan proteksi pada motor listrik. Hasil dari pelatihan ini termasuk peningkatan pengetahuan mendalam tentang proteksi motor listrik, keterampilan dalam implementasi sistem proteksi, dan kemampuan pemeliharaan. Para peserta mampu mengidentifikasi risiko beban lebih dan menerapkan sistem proteksi yang tepat. Hal ini membantu mengoptimalkan penggunaan energi, meningkatkan efisiensi operasional perusahaan, dan mengurangi kerusakan dan gangguan produksi.
