Abstract:
Rubber plant (Havea brasiliensis) produce natural latex. By product of this plant was
rubber seed that having nutritive value. Now days some farmers used this seed in poultry diet as
animal feedstuffs. Because of its nutrient content, rubber seed had a great potential to be as
economically materials for food, feed or material for industry. The purpose of this research was
to obtain the best treatment of smoking time on rendement and chemical properties of rubber
seed oil that could be used as edible oil. This research was conducted by using the Complete
Random Block Design consists of 4 treatments with 3 replications as a blocks. The treatments
were duration of smoking, respectively 12, 16, 20 and 24 hours. The data obtained then be
analyzed statistically by using ANOVA. The Results of study showed that duration of smoking a
real effect (P <0.05) on rendement and water content of rubber seed oil yield, whereas treatment
did not affect significantly (P> 0.05) on the peroxide number, iodine number, acid number,
density, color and aroma of oil. Based on the results it can be concluded that the duration of
smoking for12 to 24 hours make the quality of rubber seed oil was that oil not feasible as the
cooking oil.
