Assessment of inter simple sequence repeat (ISSR) technique in mangosteen (Garcinia mangostana L.) grown in different Sumatra region

Posted Posted in Publikasi Internasional, Publikasi Internasional, Year 2010, Year 2010

Abstract. Inter-simple sequence repeat (ISSR) markers were used to examine the level of genetic diversity in mangosteen. Twenty three accessions of the Garcinia mangostana collection from Sumatra region were screened for ISSR markers. Eleven random ISSR primers were chosen to differentiate the investigated accessions. The primers generated 72 bands of which 42 (58%) were polymorphic […]

Morphological variability of apomictic mangosteen (Garcinia mangostana L.) in Indonesia: Morphological evidence of natural populations from Sumatra and Java

Posted Posted in Publikasi Internasional, Publikasi Internasional, Year 2010, Year 2010

Summary. Indonesia is one of the most important mangosteen producing countries whose the growing areas are scattered on almost all of the islands. Mangosteen variability was observed based on field expeditions from 1992 to 2005. The data were collected on morphological observations on mangosteen production centres in West Sumatra, Riau, Jambi, South Sumatra, Bengkulu, Bangka/Belitung, […]

Comparison of static-mixer and blade agitator reactor in biodiesel production

Posted Posted in Publikasi Internasional, Publikasi Internasional, Year 2010, Year 2010

Abstract. One of the difficulties faced in the current technology for biodiesel production is the requirement for rigorous mixing of methanol with the feedstock oil in the reactor. Utilization of blade mixer is limited by the immiscible state of those substances. This research is devoted to the assessment of static-mixer utilization in a transesterification reactor […]
