Sistem rem tromol pada kendaraan menghasilkan panas yang cukup tinggi akibat gesekan antara kampas rem dan permukaan tromol, sehingga diperlukan metode pendinginan yang efektif untuk menjaga kinerja dan keamanan sistem pengereman. Salah satu metode yang dapat digunakan adalah pendinginan menggunakan udara bertekanan yang disemprotkan melalui nozzle dengan ukuran tertentu. Penelitian ini bertujuan untuk menganalisis pengaruh variasi ukuran nozzle terhadap efektivitas penurunan temperatur rem tromol. Metode yang digunakan dalam penelitian ini adalah dengan melakukan pemanasan terhadap backplate tromol menggunakan hot gun hingga mencapai temperatur 150°C. Setelah itu, dilakukan penyemprotan udara bertekanan melalui nozzle berukuran 1/4 inci, 1/2 inci, dan 3/4 inci, dengan tekanan udara konstan sebesar 5 bar dan dalam kondisi lingkungan tetap. Temperatur akhir setelah penyemprotan diukur untuk masing-masing ukuran nozzle pada durasi waktu10 detik. Hasil pengujian menunjukkan bahwa nozzle berukuran besar (3/4 inci) mampu menurunkan temperatur tromol secara lebih signifikan dibandingkan ukuran lainnya. Semakin besar ukuran nozzle, semakin besar debit udara yang dihasilkan, sehingga proses perpindahan panas melalui konveksi menjadi lebih efektif. Dengan demikian, dapat disimpulkan bahwa ukuran nozzle merupakan salah satu faktor kunci dalam meningkatkan efisiensi pendinginan rem tromol menggunakan udara bertekanan.

Kecelakaan lalu lintas merupakan permasalahan serius yang terjadi secara global, termasuk di Indonesia. Salah satu faktor utama penyebab kecelakaan adalah kegagalan sistem pengereman, khususnya rem blong. Rem blong umumnya disebabkan oleh overheating pada sistem rem, yang mengakibatkan berkurangnya daya cengkeram rem atau munculnya vapor lock, sehingga pengemudi tidak dapat mengendalikan kendaraannya. Kondisi ini sangat berisiko, terutama pada kendaraan bermuatan berat seperti truk, bus, dan mobil pick-up. Panas berlebih pada sistem rem terjadi karena gesekan saat pengereman menghasilkan temperatur yang melampaui kapasitas sistem, sehingga mempercepat kerusakan dan meningkatkan potensi kecelakaan. Salah satu solusi untuk mengatasi hal ini adalah dengan menjaga temperatur rem tromol, yaitu melalui sistem pendingin otomatis menggunakan udara bertekanan yang diarahkan ke rem tromol. Metode ini  mencegah kegagalan sistem rem akibat panas berlebih dan meningkatkan keselamatan kendaraan berat. Penelitian ini dilakukan pada prototipe rem tromol untuk menguji efektivitas udara bertekanan (5 bar) dengan memvariasikan jarak nozzle (8 mm, 10 mm, dan 12 mm) dengan sudut nozzle (45°) secara otomatis menggunakan Arduino Mega 2560. Tujuan dari penelitian ini adalah untuk mendapatkan data yang akurat mengenai jarak yang paling berpengaruh dalam menurunkan temperatur rem. Hasil terbaik diperoleh pada jarak yang tedekat yaitu 8 mm, dengan temperatur pendinginan terendah sebesar 127,64°C.

Abstract: This research systematically concentrates on the effect of different dyeing temperatures on the mechanical properties of AISI 1045 steel which has an important role in the field of mechanical engineering. These findings are important for the development of engineering components such as shafts and gears. This study aims to analyze the effect of quenching temperature variations on the hardness, tensile strength, and ductility of AISI 1045 steel experimentally. Heat treatment was carried out through samples up to an austenization temperature of 850°C with a holding duration of 30 minutes, followed by flash dipping (rapid cooling) using water media at temperature variations of 5°C, 15°C, 25°C, and 35°C. Each treatment was carried out five times and statistical analysis was given to obtain representative data. Observation of microstructures using serial light microscopy was carried out including evaluation. The results showed a close relationship between the decrease in coolant temperature and the increase in hardness and tensile strength. However, there is an opposite correlation with material durability. The highest hardness, 58 HRC, and the strongest tensile strength, 1250 MPa, were obtained for samples cooled at 5°C.  Microstructure observations show a more dominant martensite formation at cooler immersion temperatures. The results of this study provide insight into the correlation with the transformation of the mechanical and microarchitectural characteristics of AISI 1045 steel.
