<![CDATA[The purpose of this research was to examine the effect of phytohormone and its concentration on germination of 1-week storage G. versteegii’s seeds. Factorial Completely Randomize Design was used with two factors: type of phytohormone (J1:Atonik, J2:gibberellic acid) and phytohormone concentration (K1:200ppm, K2:400ppm). ANOVA shows that phytohormone concentration was the only factor that has a significant difference at α=0.05. Four hundred ppm was an ideal concentration that supports G. versteegii’s seed's better germination rate on atonic and gibberellic acid. However, gibberellic acid has supported a better germination rate than atonic at 400 ppm concentration. It is concluded that gibberellic acid at 400 ppm concentration is the best treatment for G. versteegii germination.]]>

<![CDATA[Bioethanol is a future renewable energy for gasoline substitution. Market need for bioethanol has been increased significantly in a decade. That will lead to unbalance between bioethanol supply and bioethanol demand if bioethanol production only come from starch and sugar source (first generation of bioethanol). Using lignocellulose waste (second generation of bioethanol) which abundand in Indonesia is one of good solution for this problem. Rice Straw production in Indonesia approximately 103.57 million ton in a year which make it is the most abundant lignocellulosa waste in this country. Optimizing bioethanol production using rice straw need two adjustment step. First step is adjustment in pre-treatment which important to breakdown insoluble lignin from the waste. Second step is selecting bioconvertion agent that has ability to carry single step fermentation process. Thermophilic clostridium is one of best bioconvertion agent for this process which has several advantage compare to others bioconvertion agent. This will lead to increase of bioethanol production to balance between bioethanol supplay and bioethanol demand.]]>

<![CDATA[The purpose of this research is to compare topology of dendrogram and cladogram of G. versteegii and others Gyrinops members for polyphasic taxonomy approach. Character of leaf, stem, flower and fruit of Gyrinops member were used for numeric phenetic analysis. On the other hands, trnL-trnF interspacer of chloroplast gene sequence were used for phylogenetic analysis. MVSP 3.1A were used for dendrogram construction using Simple Matching Coefficient and Jaccard’s Coefficient as clustering method. Co-stat cohor 6 were used for cophenetic correlation analysis. Multiple sequence alignment of trnL – trnF was carried by ClustalX 2.1 program. MEGA program was used for reconstruction of cladogram. This cladogram uses two different approach algorithms including: Neighbor Joining and Maximum Likelihood with 1000 bootstrap replication. Sequences similarity matrix analysis were carried by Phydit program with cut off value 99% for each Gyrinops members. Based on result, simple matching dendrogram has the same topology as Jaccard’s dendrogram. Cophenetic correlation analysis also confirm that there is no distortion on clustering analysis of these two dendrograms. On the other hand, Neighbor Joining cladogram has different topology from Maximum Likelihood cladogram. Similarity analysis of trnL-trnF sequence shows that each member of Gyrinops has strong phylogenetic relationship. Comparation of dendrogram and cladogram of G. versteegii with other Gyrinops members confirm that this species has different clustering group on dendrogram and cladogram. It could be concluded that G. versteegii has unique phylogenetic relationship and similarity relationship with others Gyrinops members.]]>

<![CDATA[Aquilaria and Gyrinops are the most common genera of Agarwood in Indonesia. These two group have wide distribution in Indonesia. Therefore, Indonesia is one of the biggest agarwood commodity producer in the world. However, the resin on agarwood stem is still main utilization of agarwood commodity in this country. Diversification agarwood utilization other than resin is needed to maximilize the potency of this commodity. Agarwood leaves are one of by product from agarwood cultivation that rarely been utilized. Agarwood leaves contain secondary metabolites that have medical effect such as Phenol, Flavonoid, Terpenoid , Alkaloid and Tannin. Thus, agarwood leaves has a good potency as a source of food and beverage product that have a medicinal effects. Agarwood leaves form Aquilaria group and Gyrinops group both have medicinal effect including antioxidant, antibacterial, cytotoxic and anticancer. Aquilaria leaves also has additional medicinal effect including: anti-inflammatory, anti-diabetic and laxative while Gyrinops leaves also has additional medicinal effect as antiradical source of sunscreen.]]>
