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 […]

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, […]

Nusantara Bioscience 2: 23-33. The aim of this research was to increase genetic variability of mangosteen (Garcinia mangostana L.) irradiated by gamma rays dosage of 0 Gy, 20 Gy, 25 Gy, 30 […]

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 […]
