Availability of moleculer marker to identify the important agronomic character of plant is needed to accelerate selection activity of plant. Particularly for the complex quantitatively inherited traits - like e.g. shading tolerance of soybean - the use of such a technique will speed up the process to produce adapted genotypes.The objective of this research is to identify the linkage of molecular marker RAPD with character of shading tolerance. The morphological specific characters wich is corelated to shade tolerance is the number of productive branchs. The intensity 75% of artificial shading is optimal level for doing selection of soybean genotypes. The inheritance of shading tolerance of soybean was controlled by gene with full dominant or by two genes pairs with dominant and ressesive epistasis. There was no maternal effect in the inheritance to shade tolerance. Heritability value (0.45 – 0.54) indicated that the proportion variation caused by the genetic factors was moderate. Molecular analysis by using RAPD technique showed that UBC153, ROTH 480.01, and ROTH 480.03 primer have polymorphic band that can be used for inheritance study and linkage analysis. All polymorphisms segregated independently of each ather. Interval mapping with Mapmaker/QTL indicated that the location of the three QTLs on linkage group were at marker tolerance locus of Roth 480.01-8125 , Roth 480.03-1125, and UBC 153-19125 .

The transportation sector is the second largest final energy consumer after the industry sector. The main energy issue in the transportation sector in Indonesia is the dominant use of oil fuels. Moreover, almost 60% of total oil fuels are being subsidized. On the contrary, the development and application of New and Renwable Energy (NRE) in the transportation sector has not been very successful. This paper applies the Analytical Hirarchy Process (AHP) in conjuction with optimization of the energy system using MARKAL model to select the best strategy for increasing the role of New and Renewable Energy (NRE) in the transportation sector. Three case studies are applied to evaluate the intervention by policy as an effort to increase the role of NRE in the transportation sector.

Most of Country Border Area in Indonesia are underdeveloped area with limited social and economic infrastructure. On the adjacent area, the neighbor country such as Malaysia that adjacent with Sumatera already developed growth centersand border corridors with so many economic activities and trade. The disparity among country can not be avoided, mostly in economic aspect. To develop Country Border Area as equal with neighbor country and surrounding area, it is needed policy to establish Economic Development Area (KPE) in Country BorderArea. KPE is an area consist of some districts in border area that functionally bond to develop integrated superior economic. One of KPE developed is KPE Bagansiapiapi in Riau Province that adjacent with Malaysia. It has strategic location and abundant natural resources, but limited infrastructure as a constrainon economic development. For that reason, it is needed to formulate KPE Bagansiapiapi Strategic Plan based on agropolitan-marine integrated development area (AMIDA) concept.

Aspergillus terreus is a Saprophyte fungus that produces several secondary metabolites as lovastatin (anti-cholesterol drug) and itaconic acid (a polymer material). Lovastatin is one of the statin class of drugs that have efficacy as antihypercholesterolemic. Plasmid transformation is the introduction and incorporation of exogenous plasmid into cells orprotoplast. In this study, pTRLI plasmid (pTRI inserts containing lovE gene as a regulator gene in the biosynthesis of lovastatin) will be transformed by electroporation transformation. The purpose of this research is transformation of pTRLI plasmid into protoplasts of Aspergillus terreus by electroporation and obtain stable transformants. The research was initiated by isolation of pTRLI plasmid. Then pTRLI plasmid was determined purity and concentration by nanodrop. Furthermore, Protoplasts of Aspergillus terreus were isolated enzymatically by adding an enzyme which can degrade the cell wall of Aspergillus terreus which contains chitin and cellulose. PTRLI plasmid were transformed into protoplasts of Aspergillus terreus by electroporation. These transformants were grown in Czapek-Dox medium containing pyrithiamine agar and the number of transformants mg-1 of pTRLI plasmid was calculated. Transformants were selected to grow in Czapek-Dox medium containing piritiamin 1 mg l-1. The number of transformants produced 187 transformants mg-1 of PTRLI plasmid. Transformants are stable up to five generations by growing the transformants in Czapek-Dox medium agar containing piritiamin 1 mg l-1. The success of the transformation indicated by ptrA gene in transformants that can be amplified by PCR. The size of fragment DNA is 801 bp.
