Solar, Cetane Number, Calculated Cetane Index, DistilasiAbstract
Kualitas penyalaan bahan bakar solar dinyatakan oleh cetane number (bilangan setana). Penentuan cetane number pada penelitian ini menggunakan korelasi empiris antara densitas dan suhu distilasi dengan standar Calculated Cetane Index (CCI) ASTM D 4737. Pemotongan trayek titik didih solar kilang dilakukan untuk mengetahui pengaruhnya terhadap nilai Calculated Cetane Index (CCI). Pemotongan trayek titik didih dilakukan dengan cara cutting distilasi menjadi 3 variasi. Calculated Cetane Index diukur dengan perhitungan antara data densitas ASTM D 4052 dan distilasi ASTM D 86. Solar Induk yang awalnya memiliki nilai CCI 46, dipotong fraksi beratnya secara bertingkat menjadi variasi 2, nilainya menurun hingga menjadi 41,6. Pada variasi 3, dilakukan pemotongan fraksi ringan secara bertingkat, hasilnya nilai CCI meningkat hingga 55,2. Hasil karakterisasi Fourier Transform Infrared Spectroscopy (FTIR) menunjukkan adanya gugus fungsi C-H stretching dan C-H bending pada bilangan gelombang 2900 cm-1 dan 1456 cm-1. Komposisi heksadekana yang semakin banyak ditemukan pada nilai CCI yang semakin tinggi. Hasil analisis menggunakan instrumen Gas Chromatography-Mass Spectrometry (GC-MS) membuktikan bahwa Solar 3.4 memiliki kandungan heksadekana yang paling tinggi yaitu sebesar 10,19%. Solar Induk memiliki kandungan heksadekana 6,45% sedangkan Solar 2.4 memiliki kandungan heksadekana yang paling rendah yaitu 4,56%.
