Analisis Pengaruh Proses Heat Treatment Terhadap Sifat Kekerasan Pada Mata Pisau Dodos kelapa sawit

This study aims to analyze the effect of the heat treatment process on the hardness of oil palm harvesting blades (dodos) using different cooling media, namely brine, oil, and water. The heat treatment process involved heating the material to the austenitizing temperature, followed by rapid cooling (quenching) using each of the media. The Rockwell hardness test was employed to evaluate changes in the material’s mechanical properties. The results showed that the type of cooling media significantly affected hardness levels, with brine producing the highest hardness compared to oil and water. These findings provide valuable recommendations for selecting the most effective cooling medium to enhance the durability and performance of oil palm dodos.
