pentandra) and biosolar has been conducted. Biosolar and biodiesel mixed with 5 different composition:
B0 (100% biodiesel), B10 (10% biodiesel), B20, B30, and B100 (100% biodiesel). Laboratory experiment
was conducted to obtain several fuel characteristics: heating value, flash point, density, and viscosity.
Biosolar is evaporated at a temperature of 120°C and then the steam is flowed to a bunsen burner with a
fixed discharge (2 ml/minute) and mixed with air in the equivalent ratio variation (?) 0.8; 1; and 1,2 and
turned on. The resulting flame was recorded with the camera and an analysis of the flame was carried
out. Thermal characteristics of this biodiesel have properties in accordance with biosolar standards of
PT Pertamina Indonesia. The heating value of biosolar is 10,602 cal/gram and biodiesel is 8,641
cal/gram, and the mixture has heating value among them. As for the characteristics of the flame with high
heat values, the core of the flame is covered in blue which shows the highest heat value.
