[ 1 ] - Ultrasound Assisted In Situ Esterification of Rubber Seeds Oil for Biodiesel Production (RESEARCH NOTE)
Since the conventional esterification method requires longer processing time and obtain low yield, the intensification of this process is still interesting subject to be investigated. To reduce the oil extraction cost from seeds which almost 70% of total processing cost, in situ esterification has been recently introduced. The objective of study was to produce biodiesel from rubber seeds oil th...
[ 2 ] - Phytoremediation of Palm Oil Mill Effluent by using Pistia Stratiotes Plant and Algae Spirulina sp for Biomass Production (RESEARCH NOTE)
Producing crude palm oil (CPO) will have side effect on producing palm oil mill effluent (POME). Besides of high COD /BOD contents, POME still contains high amount of nutrients (nitrogen, phosphor and mineral). Traditional treatment of palm oil mill effluent using facultative anaerobic method not fully eliminated COD and BOD into allowable limit. The objective of this research was to utilize p...
