Abstract

UKM Wintolo is a small and medium business that produces molds using liquid aluminum as the base material. UKM Wintolo has 3 workers with different age ranges. When initial observations were made, it was seen that the position and posture of workers when working were not neutral and not ergonomic, so community service activities were carried out at UKM Wintolo with the theme of improving processes and work environments in accordance with ergonomics rules at UKM Wintolo. This activity was carried out for 2 days, namely the first day was carried out by providing socialization material according to the theme of the activity, and taking measurements using the anthropometric method in making work facilities. The work facilities that have been refurbished include work chairs that are used for the mold preparation process and the process of taking mold results. On the second day, the products that had been made for these two activities were handed over. Community service activities are carried out to avoid musculoskeletal disorder (MSDs) complaints and this will subsequently have an impact on increasing worker productivity. Through this activity, it can be seen that there is a change in the position and posture of workers while working.

Abstract

Rem merupakan elemen penting untuk menjaga kemampuan manuver dan keselamatan pada kendaraan apa pun, baik yang berputar maupun linier. Sistem pengereman bekerja dengan memanfaatkan gesekan antara cakram dan bantalan, untuk memperlambat kendaraan yang bergerak. Tujuan penelitian ini untuk pembaruan dengan mengintegrasikan analisis thermal transient dan static structure secara bersamaan pada model rem cakram berbasis fenite element. Desain disc brake menggunakan software solidwork dan materialnya menggunakan cast iron steel. Parameter yang digunakan adalah temperatur lingkungan, heat power dan convection. Hasil kualitas mesh yang dengan elemen yang bervariasi untuk menyesuaikan bentuk geometri kompleks, sehingga mendukung akurasi simulasi. Hasil analisis thermal transient menunjukkan adanya distribusi temperatur suhu maksimum mencapai sekitar 101,47°C dan suhu minimum hingga -149,28°C. Kemudian analisis static sctructure menunjukkan nilai tegangan minimum sekitar 9,53×102 N/m², sedangkan nilai maksimum sekitar 3,42×106 N/m². Dari sisi mekanis, tegangan von Mises maksimum yang terjadi jauh di bawah batas leleh material dan mampu menahan beban kerja normal tanpa risiko kegagalan struktural.
