Abstract
This study addresses the problem of brake failure in automatic motorcycles on downhill roads, which is often caused by an increase in drum temperature due to excessive friction that is not monitored in real time. Although previous studies have discussed the effectiveness of drum cooling systems, there is still a research gap in determining the ideal braking interval to keep the brake temperature within safe limits. The main research questions include the extent to which excessive friction contributes to critical temperature increases and how extreme temperatures affect braking effectiveness. The methodology used involves field experiments using a Honda Vario 125 automatic motorcycle equipped with a GY-906 BCC temperature sensor and an ESP32 microcontroller to record drum temperature data, braking time, and testing locations on the downhill road in Karawang. Test results show that repeated friction over short time intervals causes significant heat accumulation, with drum temperatures reaching up to 109.37°C at a load of 130 kg. The braking effectiveness of the drum brake was found to be very low, only 14.69% of the required braking force, indicating a high risk of accidents. In conclusion, the increase in drum temperature due to repeated braking significantly reduces braking effectiveness. For optimal braking, it is recommended to increase the brake lever pull force to a minimum of 120 N, use brake pads with a high friction coefficient (≥ 0.6), and maintain a minimum braking interval of 20–30 seconds to allow for natural cooling. The implementation of dual braking technology or ABS is also recommended to enhance safety. Keywords: drum brake, automatic motorcycle, downhill road, braking interval, brake failure Penelitian ini mengatasi masalah kegagalan pengereman pada motor matic di jalan menurun, yang sering disebabkan oleh peningkatan suhu tromol akibat gesekan berlebih yang tidak terpantau secara real time. Meskipun studi sebelumnya telah banyak membahas efektivitas sistem pendinginan tromol, masih terdapat research gap dalam penentuan interval pengereman ideal untuk menjaga suhu rem dalam batas aman. Rumusan masalah utama mencakup sejauh mana gesekan berlebih berkontribusi pada peningkatan suhu kritis dan bagaimana suhu ekstrem memengaruhi efektivitas pengereman. Metodologi yang digunakan adalah eksperimen lapangan menggunakan motor matic Honda Vario 125 yang dilengkapi sensor suhu GY-906 BCC dan mikrokontroler ESP32 untuk merekam data suhu tromol, waktu pengereman, dan lokasi pengujian di jalan menurun Karawang. Hasil pengujian menunjukkan bahwa gesekan berulang dalam interval waktu pendek menyebabkan akumulasi panas signifikan, dengan suhu tromol mencapai hingga 109.37°C pada beban 130 kg. Efektivitas pengereman rem tromol terbukti sangat rendah, hanya 14.69% dari gaya pengereman yang dibutuhkan, mengindikasikan risiko kecelakaan tinggi. Kesimpulannya, peningkatan suhu tromol akibat pengereman berulang secara signifikan mengurangi efektivitas pengereman. Untuk pengereman optimal, disarankan peningkatan gaya tarik tuas rem hingga minimal 120 N, penggunaan kampas rem dengan koefisien friksi tinggi (≥ 0.6), dan interval pengereman minimal 20-30 detik untuk memungkinkan pendinginan alami. Penerapan teknologi pengereman ganda atau ABS juga direkomendasikan untuk meningkatkan keselamatan. Kata kunci: rem tromol, motor matic, jalan menurun, interval pengereman, kegagalan rem.
