The purpose of this research was to analysis moleculer varians of genetic material of oil palm based on 4 SSR markers, there were mCnCIR0038, mEgCIR0894, mEgCIR3292 and mEgCIR3663. DARwin 6.0 was used to analysis of the data. The results of this research showed that genetic moleculer varians based on SSR markers was 41.68%

Respon Pertumbuhan Dan Biomassa Semai Rhizopora Apiculata BI Terhadap Salinitas Dan Kandungan Lipidanya Pada Tingkat Pohon

Growth and biomass Rhizopora apiculata BI seedlings under varied salinities and their lipid content at tree stage. The research was conducted at Green house, Faculty of Agriculture and Research Laboratory, Faculty of Pharmacy, University of North Sumatra from August 2011 to July 2012. This study aims to determine the effect of salinity on the growth and biomassa of mangrove non secreter R. apiculata seedlings level and lipid and NSL (Nonsaponifiable Lipids) content at tree level. Five levels of salinities of 0%, 0.5%, 1.5%, 2%, 3% were treated and seedlings were planted for 5 months. The results showed that maximum growth of R. apiculata seedling at 1.5% concentration, leaf number and leaf area were in the salinity of 0.5%. Stem and root biomass achieved in 1.5%, while the leaf biomass in the salinity of 0.5%. The content of total lipid and NSL obtained from the leaves and the roots R. apiculata tree. The content of total lipid R. apiculata trees in the leaves (9.60 mg) were more amounts than in the roots (6.40 mg). NSL content of R. apiculata trees in the roots (0,226 mg) were more than in the leaves (0.10 mg). The results of this study may provide information to the rehabilitation program in order to obtain R. apiculata seedlings growing best based on their salinities

Keragaman Genetik Tiga Populasi Kelapa Sawit (Elaeis Guineensis Jacq.) Tipe Pisifera Berdasarkan Marka Rapd

Palm oil producing oil is one of the famous of oil palm plantations as a source of producer non- petroleum oil for Indonesian foreign exchange. Superior varieties of palm oil produced by various research institutions that is tenera originated crossly from dura x pisifera (DxP). Pisifera has an important function in the production of seed of oil palm. Pisifera population is very important to be managed and developed . A RAPD is a method to identify a number of large polymorphism DNA in the genome quickly, efficiently and suitable for the study of genetic diversity. The purpose of this research is to analyze genetic diversity on pisifera type of palm oil by three population namely Yangambi origin, LaMe origin and LaMe silang lanjut in Bangun Bandar seed productions PT Socfin Indonesia analyzed by RAPD markers. Eighteen sample for each pisifera population of Yangambi origin, LaMe origin and LaMe silang lanjut showed moderate level of genetic diversity which is shown the average value of 0.24 with the highest was 0,28 and the lowest value was 0.21. The percentage of highest polymorphic on the primer 15 and primer 19 of LaMe origin which reached 100%. The Polymorphic information content (PIC) highest on the primer 11 was on Yangambi origin and primer 10 was laMe silang lanjut of 0.49, while to the lowest PIC on primer 21 of LaMe origin was 0.01

Komposisi Senyawa Isoprenoid Pada Mangrove Sejati Minor Jenis Teruntun (Aegiceras Corniculatum (L.) Blanco) Sebagai Biomarker Di Daerah Estuarina

This study described the analyzing of composition and diversity of triterpenoid and phytosterol in North Sumatera mangrove species A. corniculatum as biomarkers and input lipids in to estuarine ecosytem. Phytosterols found in the roots and leaves of A. corniculatum were stigmasterol, campesterol, β-sitosterol, and cycloartenol. Taraxerol, β-amyrin, germanicol, betulin, α-amyrin, lopenone and lupeol were the triterpenoids identified. Betulin was the major component triterpenoids had the highest content (31,8%) in the roots. This research may provide information the composition of triterpenoid and phytosterol to contribute to estimating the lipid input and as biomarker from A. corniculatum to estuarine ecosytem

Karakterisasi Senyawa Isoprenoid Dan Pertumbuhan Semai Mangrove Avicennia Alba Bl.

This study aims to determine the characterization of isoprenoid compounds in the mangrove A. alba and seedling growth of A. alba at different levels of salinity. The results showed the total lipids in the leaves of A. alba (21 mg) was higher than that in the roots (11,7 mg). Total Non Saponifiable Lipids (NSL) content in the leaves of A. alba (1,1 mg) greater than that in the roots (0,6 mg). NSL composition of A. alba consists of 3 major factions namely triterpenoids, phytosterols, and other compounds. Phytosterol composition in the leaves and roots of A. alba showed the presence of compounds such as campesterol, stigmasterol and β-sitosterol. As frase for the composition triterpenoid found the presence of β-amyrin, germanicol, betulin, lupeol and α-amyrin. Phytol, cholesterol, and squalene were also found as the other compounds. The content of the NSL triterpenoid was higher than phytosterol in the leaves and roots of A. alba. The results also showed that phytol compounds had the highest content of leaves of A. alba (71.4 %) and the β-sitosterol had the highest content of root A. alba (27.8 %). Based on the analysis of the effect of salinity on seedling growth of A. alba showed that the salinity of 2% significantly affected the seedling height and diameter of 3 months of A. alba

Respons Cekaman Garam Terhadap Pertumbuhan Dan Konsentrasi Rantai Panjang Polyisoprenoid Pada Mangrove Sonneratia Alba Smith.

Mangrove is one of the richest bioactive source naturally and is able to remove excess of salt. The purpose of this study was to determine optimum salinity concentration for growth of S. alba seedlings and to evaluate effect of salinity on polyisoprenoid composition. S. alba seedlings were used with 5 treatments namely 0%, 0,5%, 1,5%, 2%, and 3% grown for 3 months. Results showed that optimum growth for S. alba seedlings characterized by height, diameter, and dry weight of root in 1,5% salinity, the best number of leaves and moisture content of root were in 0,5% salinity. On the other hand, dry weight of shoot, moisture content of shoot, and ratio of shoot to root were found in 3% salinity, respectively. Analysis of Polyisoprenoid in S. alba seedlings in 3% salinity was higher concentration than 0% treatment
