AB  - Biodiesel can be an alternative fuel in Indonesia and can be made from various ingredients. Waste
coconut is one of the ingredients that biodiesel can make because it still contains oil around 15-24% of its
weight. This study was conducted to determine the characteristics of burning biodiesel from waste coconut.
Burning is carried out premixed using a bunsen burner mm at the equivalent ratio of 0.8; 1 and 1. 2. The fuel
used is biosolar that producted of PT Pertamina Indonesia mixed with biodiesel from waste coconut with
variations in the composition of 0 (B0), 10% (B10), 20% (B20), 30% (B30) and 100% (B100). The flame on
the bunser burner is measured it’s the flame temperature and taken photographed to obtain the flame height
and combustion speed. The results showed that the addition of this type of biosiesel to biosolar lowered the
flame temperature because the biodiesel heating value was lower than the biosolar of Pertamina products. This
was proven that the decrease in flame temperature caused the flame height to increase and the combustion speed
decreased, so that, the biodiesel evaporation process took longer than the biosolar produced by Pertamina.
