Abstract

Saron or commonly called ricik is a gamelan instrument that belongs to the balungan family. In a set of Surakarta style gamelan usually has two pairs of saron barrel pelog and slendro. Saron is made from a blend of copper (Cu) and tin (Sn), with a ratio of three to ten alloys where 22% tin (Sn) and 78% copper (Cu)One of the manufacturing processes is the quenching process. In this process, it was generally done by using water cooling media. Therefore, this time a study was conducted to compare the quenching process using various of cooling media including water, oil and air.From the results of testing the hardness value there is a difference between using water, oil and air cooling media. For the result, the hardness value with water cooling media is 196 BHN, oil is 254 BHN and air is 231 BHN. From the results of the surface roughness test, the following results show that the roughness value of saron blades with water cooling media has a roughness value of 1.2380 µm, for oil cooling media it is 0.3435 µm, and for air conditioning media it has a value of 0.2956 µm. The results of the microstructure test showed differences in the size of the copper (Cu) structure. And the results for testing the chemical composition there were differences in the percentage composition of copper (Cu) and tin (Sn), where for cooling media the Cu content was 77,50% and Sn 21.74%, for oil cooling media the Cu content was 77.51% and Sn 22.24%, for air conditioning media the content of Cu is 76,12% and Sn is 21.90%.
