Penelitian ini bertujuan untuk mencari bahan bakar alternatif pengganti solar industri yang dimanfaatkan sebagai bahan bakar burner. Bahan bakar alternatif dibuat dengan proses blending (mencampur) IFO:kondensat dan MFO:kondensat pada kenaikan rasio 10% dengan komposisi IFO:kondensat (10:90, 20:80, 30:70, 40:60, 50:50) dan MFO:kondensat (10:90, 20:80, 30:70, 40:60). Komposisi blending yang diharapkan yaitu blending dengan karakteristik sesuai dengan solar industri (dari segi viskositas). Masing-masing hasil blending diuji karakteristiknya. Pengujian tersebut meliputi pengujian viskositas, specific gravity, nilai kalor, water and sediment, kadar abu, residu karbon, Fe, sulfur dan uji bakar. Parameter yang dijadikan acuan utama yaitu viskositas. Dari hasil pengujian viskositas, yang mendekati viskositas solar industri (4,97 cSt) yaitu blending IFO:kondensat 50:50 (4,28 cSt) dan MFO:kondensat 40:60 (4,97 cSt). Kedua komposisi blending inilah yang kemudian sesuai untuk menggantikan solar industri. Perbandingan karakteristik dan spesifikasi blending IFO:kondensat (50:50) dan MFO:kondensat (40:60) masing-masing adalah: (a) specific gravity: 0,8686 g/m3 dan 0,8505 g/m3, (b) nilai kalor IFO:kondensat (50:50): 10203,6 Kcal/Kg, (c) water and sediment: 0,1875% dan 0,2300%, (d) kadar abu: 0,005% dan 0,006%, (e) residu karbon: 2,77% dan 4,29%, (f) Fe: 9,534 ppm dan 8,114 ppm, dan (g) sulfur: 0,21% dan 0,31%. Semua karakteristik tersebut masih sesuai dengan karakteristik dalam bahan bakar yang diatur dalam regulasi negara. Hasil uji bakar menggunakan burner (panjang api dan laju konsumsi bahan bakar), menyimpulkan bahwa semakin meningkat input udara, panjang nyala api semakin meningkat dan konsumsi bahan bakar akan semakin meningkat pula.

This research aims to find an alternative of industrial fuel that used as an burner's fuel. Alternative fuel was made by blending IFO:condensate and MFO:condensate on the rise in the ratio of 10% with the composition IFO:condensate (10:90, 20:80, 30:70, 40:60, 50:50) and MFO:condensate (10:90, 20:80, 30:70, 40:60). The Blending composition that expected was the blends which have the characteristics that accordance with the industrial fuel's characteristics (in terms of viscosity). Characteristics of each blending result was tested. The testing includes viscosity, specific gravity, calorific value, water and sediment, ash content, carbon residue, Fe, sulfur and fuel test. The parameters that used as the main reference is viscosity. From the result of viscosity test, viscosity that was approximately with the industrial fuel's viscosity (4.97 cSt) is the IFO:condensate 50:50 blending (4.28 cSt) and MFO:condensate 40:60 blending (4.97 cSt). Both of the blending composition appropriate to replace the industrial fuel. The comparison of characteristics and specifications of IFO:condensate (50:50) blending and MFO:condensate (40:60) blending, respectively: (a) specific gravity: 0.8686 g/m3 and 0.8505 g/m3, (b) the calorific value IFO:condensate (50:50): 10203.6 Kcal/Kg, (c) water and sediment: 0.1875% and 0.2300%, (d) ash content: 0.005% and 0.006%, (e) carbon residue: 2.77 % and 4.29%, (f) Fe : 9.534 ppm and 8.114 ppm, and (g) total sulfur: 0.21% and 0.31%. All of these characteristics were accordance with the characteristics of the fuel that regulated in the state regulations. Test results using a fuel burner (flame length and rate of fuel consumption), concluded that increasing of air input, flame length and fuel consumption will increase as well.
