Abstract

Arpiwi  NL, Wahyuni IGAS, Muksin IK, Sutomo. 2018. Conservation and selection of plus trees of Pongamia pinnata in Bali, Indonesia. Biodiversitas 19: 1607-1614. Pongamia pinnata (L.) Pierre or commonly known as pongamia is a tropical legume tree produces oil seeds for biodiesel feedstock. The aims of present study were mapping growth sites of pongamia in Bali,  counting the number of trees and selecting plus trees based on growth parameters such as total height, clear bole height, diameter at breast height, canopy width, and oil content. Method of plus tree selection was comparison tree where one candidate tree was compared with 5 nearby check trees from each village. A total of 126 pongamia trees were found in coastal beach of Bali. The majority of trees were in the north west of the island.  Temperature ranges from 26-28oC, humidity ranges from 74-80% and altitude 5-50 meters above sea level. Eight pongamia plus trees were selected from 4 villages namely Kalibukbuk, Pengulon, Pemogan, and Sanur. In conclusion, pongamia was mostly distributed in the northern-west part of the Bali Island of Buleleng District. Lower number of trees was also found in the southern and western part of the island. Trees either scattered or grown in small groups. The number of pongamia tree in Bali is small and this needs further action for conserving the species.

Abstract

Andila PS, Hendra IPA, Wardani PK, Tirta IG, Sutomo, Fardenan D. 2018. The phytochemistry of Cymbopogon winterianus essential oil from Lombok Island, Indonesia and its antifungal activity against phytopathogenic fungi. Nusantara Bioscience 10: 232-239. Cymbopogon winterianus Jowitt ex Bor [Sereh Wangi] is a plant producing essential oil that has been extensively used in perfumery, mosquito repellent, medicinal, and cosmetic industry. In Indonesia, the accession of C. winterianus plant had been collected from natural forest in Sembalun, Lombok, West Nusa Tenggara (NTB) Province. However, the phytochemical properties and its biological potential of this accession have never been reported. The aim of this study was to determine the phytochemical content of essential oil of C. winterianus from Lombok and to explore its potential as a bioantifungal against several phytopathogen fungi. The essential oils were extracted from fresh stem and leaf of C. winterianus by hydrodistillation. The chemical composition of them was determined by chromatography-mass spectrometry (GC-MS). A total of 26 and 20 compounds were obtained from the stem and leaf oil with the dominant compounds of essential oil in stem were Torreyol (17.89%), Oxirane, octyl- (15.84%), (-)-Isopulegol (14.44%), Isopulegol 2 (12.18%), and Geranyl Acetate (5.89%) while in leaf were (-)-Isopulegol (22.69%), Oxirane, octyl- (16.64%), Cyclohexanol, 5-methyl-2-(1-methylethenyl)- (14.21%), "KW3 AUS Epiglobulol” (9.47%), and Cyclohexene, 1-methyl-4-(1-methylethenyl)- (7.14%). The presence of these contents as dominant chemical compounds in S. winterianus was reported for the first time. The highest content of oils was identified as monoterpene (38.01% and 45.78% in stem and leaf oil) and sesquiterpene ( 27.67% and 17.78 % in stem and Leaf oil). The biological study showed that leaf essential of C. winterianus expressed positive antifungal activity against Fusarium solani, Aspergillus niger, dan Cladosporium sp.
