The objective of the research is to find out the appropriate and beneficial forced molting program that suitable with the environment and the condition of the farmer in Indonesia. The research used 180 medium type chickens, strain Dekalb Warren, aged 84 weeks old. The research applied 2×2×2 factors and used complete randomized design in (CRD) 5 times replications with 4 chickens for each repeat. The first factor was water supplying and without water supply. The second factor was the duration of no feeding for 10 and 5 days. The third factor was the amount of feed given during recovery period, that was 50% and 25% of the normal consumption. So, the total of the treatment of forced molting program applied were 9 treatments. Data obtained were analysed using analysis of variance (ANOVA), orthogonal comparison test. The result obtained showed that the treatment B (without feeding for the first 10 days, having water supply, day 11 to 30 were feed 25% of normal consumption) could be increasing the average of egg production of old chicken to 68.20%, improving feed convertion, egg quality: Haugh Unit value, yolk percentage, significantly and no differences were obsesrved among treatments versus control for egg weighth, albumen percentage, eggshell thickness. The result was also showed that the Forced Molting Stress Method used in this experiment, would be giving profit of Rp 2,500,000;- per 1,000 chickens if implemented; in the contrary, if the old chickens are allow to keep laying egg without treatment, the farmer would get deficit of Rp 467,000;- per 1,000 chickens

Pengaruh Penerapan Good Corporate Governance, Tingkat Suku Bunga Dan Peringkat Obligasi Terhadap Yield to Maturity Obligasi

This study is aimed to give better understanding the impact of Good Corporate Governance (GCG) implementation, interest rate, and bond rating on bond Yield to Maturity (BYTM) through controlled variable namely Debt to Equity Ratio (DER) and Return on Equity (ROE). BYTM is an indicator for the investors to foresee the future value of the bond until its payment due. In order to predict how marketable a bond is, investor must consider an array of aspects, be it internally (GCG and rating) or externally (interest rate).GCG variables that had been set in this study consists of four proxies, namely institutional ownership, managerial ownership, the size of independent supervisory board, and audit commitee. During a period of 2010-2012, 84 bonds from 16 companies were sampled in this study. This study employed panel regression method to analyze the data. The results of this study has shown that proxies from GCG variables, namely institutional ownership, managerial ownership, the size of independent supervisory board, and audit commitee, impart significantly negative effects on BYTM, whereas audit commitee gives unsignificantly positive impact. Interest rate and bond rating impart significantly positive and significantly negative impacts, respectively. Controlled variables of DER and ROE does not give significant effects

MS consists of several species of genus Streptococcus which are sharing similar phenotypes and genotypes. The aim of this study is to determine the genetic diversity of the core species of clinical strains of Streptococcus mutans, Streptococcus sobrinus and Streptococcus downei by using repitative extragenic palindromic (REP) primer. The DNA of the clinical strains of S. mutans (n=10), S. sobrinus (n=05) and S. downei (n=04) have been employed in the present study, which have been previously isolated from caries active subjects. The DNA of the clinical and reference strains was subjected to PCR amplification using REP primer. The phylogenetic dendrogram is constructed from the REP PCR banding profile by neighbour-joining method using PyElph 1.4 software. The size of the DNA amplicons generated by using REP primer were S. mutans (1500 bp to 250 bp), S. sobrinus (6000 bp to 250 bp) and S. downei (5000 bp to 400 bp). The results present common band at 480 bp in all the clinical strains of S. sobrinus. The current study is the first to demonstrate the genetic variety of S. sobrinus and S. downei by using REP primer. REP-PCR have been found to be a powerful method to study the molecular diversity of S. mutans, S. sobrinus and S. downei. Additionally, further studies are suggested to analyze the species specific bands and also to find the possibility to produce a new specific primer for S. sobrinus
