Abstract

The company performance is reflected at the operational profit and  stock price. The stock price is influenced by fundamental factors and macro economic  condition of a country. Exchange rate, BI rate and inflation are  macro economic variables  that often be used to predict stock price, because the variables directly controlled  through monetary policy through Indonesian Bank (BI). The research goals  are to analyze and explain the influence of exchange rate, BI rate, and inflation  to the stock return. The used research method was qualitative with associative descriptive research type. The data collection through documentation by using secondary data that were published by Indonesian Bank (BI) and Indonesian Stock Exchange (BEI). The sample collection technique was non probability, with sample selection by purposive sampling, so obtained 12 samples of banking companies. The data analysis  by using multiple regression analysis. The results that exchange rate, BI rate, and inflation simultaneously significantly influence to the  stock price in period of 2007-2011. The variable contribution in explaining the stock return of 14,2% while the rest of 85,8% influenced by other factors. The exchange rate partially does not significantly influence to the stock return of banking companies. BI rate partially significantly influence to the stock return of banking companies. Inflation partially does not significantly influence to the stock return of banking companies. Keywords: Exchange Rate, BI Rate, and Inflation, Stock Return.   Kinerja perusahaan tercermin dari laba operasional dan harga per lembar saham.

Abstract

ABSTRACTNipah Virus Seroepidemiology in Flying Fox and Pig Husbandry in Several Areasof Indonesia. Nipah is a dangerous zoonotic disease which was carried by flying fox.The disease had been occurred in Malaysia in 1999 and infect pigs and caused humandeath. Indonesia is adjacent country to Malaysia, hence, a serological study had beenconducted on 156 flying fox (P. vampyrus) sera from North Sumatera, West Java, CentralJava and East Java. Besides that, 2740 pig sera was randomly collected in differentprovinces to detect Nipah infection. Both flying fox and pig sera were tested usingELISA test to detect the presence of Nipah antibody. The results indicated that 37 from156 flying fox sera (23.7%) has antibodies against Nipah virus. Infections were occuredin all sampling sites with the prevalence varied from 18% to 33 %. Meanwhile, no pigsera tested (2740) had antibody against Nipah virus. Based on these results it can beconcluded that Nipah virus infections were occurred in flying fox in some parts inIndonesia, but not in pigs. It was suggested that the presence of Nipah virus in Indonesiashould be anticipated. Hence the distribution of its infection in pigs and human must beanticipated. Monitoring of Nipah infection in areas adjacent to Malaysia must be increasedto detect the entering of the disease in Indonesia.Keywords: Nipah, pigs, flying fox, serology

ABSTRACTGenetic Mapping of Indonesian Avian Influenza Viruses 2007.Department of agricultureimplements vaccination as one a tool to control of avian influenza disease. The vaccinationprogram use virus seed such as H5N1, H5N2 and H5N9. Such as vaccination program for otherdiseases, avian influenza vaccine program have lack implementation in the field. In 2007,department of agriculture evaluated the AI vaccination program such as the master seedvaccine that can be used. Result of the evaluation showed that 11 of AI vaccines that weredistributed in Indonesia did not give protection more than 60% to Indonesian isolates in 2006(A/Ck/Pwt-Wij/06). From this point and many AI cases in the field in 2007, the aim of thisstudy was to conduct genetic diversity of avian influenza viruses which have circulated inIndonesia region. We used virus isolation for propagate the viruses, RT-PCR for identificationand DNA sequencing on HA1 region to analysis genetic diversity for genetic mapping anduseful for master seed candidate. The result of the study showed that there were 6 group ofgenetic diversity in 2007; Isolates from group 1, 5 and 6 can be used for AI vaccine candidate.Key words: genetic mapping, genetic diversity and avian influenza viruses
