Abstract
Minyak pelumas daur ulang dapat diketahui melalui keberadaan senyawa penanda dalam pelumas melalui analisa KG-SM. Pada penelitian ini minyak pelumas daur ulang diekstraksi menggunakan pelarut metil etil keton dengan penambahan demulsifier CaCl2 anhidrat. Perbandingan pelarut dan minyak 4:1 dengan demulsifier sebesar 1% dari jumlah total minyak dan pelarut. Hasil ekstraksi difraksinasi, fraksi yang diperoleh diidentifikasi menggunakan KG-SM. Hasil identifikasi menunjukkan terdapat senyawa baru dalam pelumas hasil daur ulang yang dapat dibedakan dengan pelumas barunya yaitu senyawa ester dengan base peak m/z 55 dan 74 serta perilen m/z 252, 266, 280 dan 294. Senyawa ester yang terbentuk adalah kelompok metil ester dari rantai panjang dengan jumlah rantai terkecil (heksadekenoat) dan rantai terpanjang (nonadekenoat). Spesifikasi perilen memiliki perbedaan rantai alifatik yang mengikat cincin perilen dengan berbagai jumlah rantai alifatik.

A recycled lubricant oil can be known through the existence of marking compound by KG-SM analysis. In this research the recycled lubricant oil was extracted by using methyl ethyl keton solvent added demulsifier CaCl2 anhidrat. The ratio of solvent and oil is 4:1 with addition demulsifier 1% of the total oil and solvent. Then the result of extraction is fractionated. The result of fractionation is identified by KG-SM analysis. The result of identification show that there is new compound in the recycled lubricant oil which can be differed with a new lubricant oil such as ester compound with base peak m/z 55 and 74, perylene with base peak m/z 252, 266, 280 and 294. The formed ester compound is methyl ester group from long chain with the sum of smallest chain (heksadecenoat) and the longest chain (nonadecenoat). Perylene specification have difference of aliphatic chain that tie perylene ring with various sum of aliphatic chain.
