Abstract

Per capita expenditure is very important for a region, It’s estimation are only conducted at national to district level based on National Socio-Economic Survey (Susenas) data conducted by BPS. The survey was designed for a national scale, so the estimation would have low precision if used for smaller sub-populations, such as villages. One attempt to improve the precision of the estimation is by increasing the effectiveness of the sample size known as the small area estimate (SAE). One method in SAE that is very well used for continuous data is the Empirical Best Linear Unbiased Prediction (EBLUP). EBLUP method is used to estimate per capita expenditure of each village in Jember District by using companion variables, the percentage of the Askeskin recipients in the last year. The result is that the estimation of village per capita expenditure in Jember Regency by EBLUP method have better precision than direct estimation. There are three outlier data including Karangrejo, Jember Lor and Sumbersari that have very high per capita expenditures because they are located in urban areas

Abstract

The diversity shown in tribes in Papua has the potential to produce varying genetic diversity. LDLR gene is a gene coding for LDL receptor proteins (LDL-R) that play a very important role in cholesterol homeostasis. The LDLR gene consists of 18 exons and 17 introns that stretch for 45 kilos of base (kb). . The exon 5 and 6 regions are important structural parts in encoding amino acids and are also ligand binding regions that mediate the interaction between receptors and lipoproteins containing Apo B-100 or Apo E. This study aims to characterize the nucleotides of Papuan populations with different origins. The method used is the polymorphism chain reaction method and sequencing method to find out the sequence of nucleotide bases. The results of the exon 5 and 6 regional nucleotide characterization of LDLR genes from 9 UNIPA students from Papua showed identical results because they had the same number of nucleotides and nucleotide arrangements. The number of nucleotides for exon 5 area is 123 pb, consisting of T = 22.0%, C = 24.4%, G = 30.9%, A = 22.8%, A + T = 44.8% and C + G = 55.3%. For exon 6 area with nucleotide amount of 123 pb, the nucleotide composition is T = 16.3%, C = 26.8%, G = 27.6%, A = 29.3%, A + T = 45.6% and C + G = 54.4%. The same results show that the two regions are conserved.

Abstract

Single nucleotide polymorphism (SNP) is a single nucleotide difference in the arrangement of DNA base strands that can show genetic variation. The LDLR gene is a low density lipoprotein (LDL-R) receptor gene that functions to regulate cholesterol levels in the blood. The LDLR gene is composed of 18 exons and contains a 3’untranslated region (3’UTR) which plays an important role in regulating gene expression. This study aims to analyze the SNP in an area of 3'UTR LDLR genes from 6 University of Papua students from Papua. The research was carried out by polymerase chain reaction method to multiply the number of target DNA, then sequenced to find out the sequence of nucleotide bases. The results of this study were from 6 individuals, found 2 SNPs at position *52 and *504 with nucleotide diversity (π) of 0.00149. These polymorphisms forms 3 types of haplotypes, namely GG, GA and AA with a haplotype diversity of 0.600 ± 0.215.

Abstract

The plant Akway (Drimys beccariana.Gibbs) is endemic to Papua and is frequently used traditionally by the Arfak tribe as a medicinal plant. We extract the plant by maceration with ethanol. The antibacterial test is done by Agar diffusion method. As microba test we used Escheresia coli and Bacillus subtilis. Result obtained from fitochemistry skrinning of the leaf and bark contained alkaloid, flavonoid, steroid, tannin, glikosida, saponin, triterpenoid, steroid and fenolik. Concentration of active substances from the leaf are flavonoid (0,3680%) and tanin (10.33 %); while from the bark flavonoid 18.35% and tanin (27.65%). Antibacterial test showed that the plant could be used as an antibaterial substances. The test showed a moderate up to a strong blocking against Escherecia coli (a gram negative bacteri) and Bacillus subtilis (a gram positive bacteri). Thus it could be concluded that the Akway plant contain a substance with a bacteriostatic nature that could block the activity of the bacteri.

Abstract

Sponges are one of the components that compose coral reef which have a potential bioactive substance that has not been utilized. Sponges are generally able to survive in marine waters were nutrients are poor because of associations with other organisms, especially bacteria. This study aimed to isolate and characterize bacteria (endosymbiont and ectosimbion) that produce antimicrobial compounds, and analyze genetic diversity based on Amplified Ribosomal DNA Restriction Analysis (ARDRA). The results of isolation obtained 138 bacterial isolates, which are 70 endofit isolates and 68 surfaces isolates respectively. The results obtained, based on antimicrobial test, was 32 bacterial isolates (45.71%) of the total bacterial isolates that have endofit antimicrobial activity, whereas on the surface bacteria, 20 bacterial isolates (29.41%) of the total surface of the bacterial isolates also have antimicrobial activity. Genetic diversity was carried out on 30 isolates that has the best antimicrobial activity. Amplyfication of 16S rRNA gene is done using specific primers, 63f and 1387r. The profile of 16S rRNA gene band shows a high diversity, which is generated after cutting with three restriction enzymes i.e. RsaI, HaeIII and HinfI. The three restriction enzymes have different cuts and properties. Construction of phylogenetic trees based on analysis of Amplified Ribosomal DNA restriction, grouped 30 isolates from the sponge Jaspis sp. which have a microbial activity on seven filotipe. This grouping is based on the similarities cuts of sites of each isolate after restriction by three different restriction enzymes.
