Analisis Pengaruh Eps, Eva dan Cash Flow terhadap Harga Saham Perusahaan Food And Beverage yang Terdaftar di Bei

This research aimed to analyze the influence of Earning Per Share (EPS), Economic Value Added (EVA) and CashFlow to the stock price of food and beverage companies listed in Indonesian Stock Exchange in 2007-2010. Thepopulation in this research was 18 companies and the samples in this research were 16 food and beveragecompanies in Indonesia Stock Exchange in 2007-2010. The sampling technique used in this study was purposivesampling. While the analysis instrument in this research was the multiple linear regression. On the test coefficient of determination, the value of adjusted R square was 0.853, which meant theindependent variable EPS, EVA and Cash Flow could explain the variability of 85.3% of the dependent variablestock price. While the remaining 14.7% explained by other causes beyond the studied variables. Thesimultaneous regression testing (F-test) indicated that the variable EPS, EVA and Cash Flow had significantinfluence to the stock price. It could be proved from the F count (55.064) was bigger than F table (2.99). In thepartial regression testing (t-test), the variable earning per share (EPS) had siginificant influence to the stock pricewith t count (9.340) was bigger than t table (2.0595). Meanwhile, the economic value added (EVA) variable didnot influence the stock price with t count value (1.697) was smaller than t table value (2.0595) and the cash flowvariable also had no influence with the t count (-0.726) was bigger than t table (-2.0595). Keywords: Eearning Per Share (EPS), Economic Value Added (EVA),Cash Flow, Stock Price

Desain Aplikasi Laporan Arus Kas Serikat Pekerja PT GMF AeroAsia Employees Club (GEC)

Arus globalisasi yang ada saat ini menyebabkan pergerakan aktivitas bisnis semakin dinamis. Pelaku bisnis berlomba-lomba menjadi yang tercepat dalam bertindak dan mengambil keputusan, yang semuanya itu tidak akan bisa dilakukan tanpa informasi. Serikat pekerja memiliki peran penting bagi Perusahaan sebagai partner memajukan USAha dan menciptakan iklim kondusif dimana seluruh pendanaan kegiatannya bersumber dari uang iuran anggota dan harus dipertanggungjawabkan melalui laporan arus kas. Faktanya laporan arus kas berjalan belum optimal karena masih dilakukan secara pembukuan sederhana, melalui tumpukan berkas dengan perhitungan manual, menyebabkan data mudah hilang dan tidak terdokumentasi dengan baik. Proses pembuatan laporan membutuhkan waktu lama sehingga mengakibatkan laporan terlambat sampai ke anggota GEC Unit. Penelitian ini dilaksanakan dengan metode analisa SWOT dan PIECES dilanjut perancangan berbasis objek menggunakan unified modelling language kemudian pemrograman dengan PHP, dreamweaver CS5, MySQL dan Xampp serta pengujian black box. Hasil akhir penelitian ini berupa aplikasi laporan arus kas serikat pekerja yang dapat meningkatkan efektifitas dan akuntabilitas

The influence of exposure and physiology on microplastic ingestion by the freshwater fish Rutilus rutilus (roach) in the River Thames, UK

Microplastics are widespread throughout aquatic environments. However, there is currently insufficient understanding of the factors influencing ingestion of microplastics by organisms, especially higher predators such as fish. In this study we link ingestion of microplastics by the roach Rutilus rutilus, within the non-tidal part of the River Thames, to exposure and physiological factors. Microplastics were found within the gut contents of roach from six out of seven sampling sites. Of sampled fish, 33% contained at least one microplastic particle. The majority of particles were fibres (75%), with fragments and films also seen (22.7% and 2.3% respectively). Polymers identified were polyethylene, polypropylene and polyester, in addition to a synthetic dye. The maximum number of ingested microplastic particles for individual fish was strongly correlated to exposure (based on distance from the source of the river). Additionally, at a given exposure, the size of fish correlated with the actual quantity of microplastics in the gut. Larger (mainly female) fish were more likely to ingest the maximum possible number of particles than smaller (mainly male) fish. This study is the first to show microplastic ingestion within freshwater fish in the UK and provides valuable new evidence of the factors influencing ingestion that can be used to inform future studies on exposure and hazard of microplastics to fish

Quantitative and qualitative differences in celiac disease epitopes among durum wheat varieties identified through deep RNA-amplicon sequencing

BACKGROUND: Wheat gluten is important for the industrial quality of bread wheat (Triticum aestivum L.) and durum wheat (T. turgidum L.). Gluten proteins are also the source of immunogenic peptides that can trigger a T cell reaction in celiac disease (CD) patients, leading to inflammatory responses in the small intestine. Various peptides with three major T cell epitopes involved in CD are derived from alpha-gliadin fraction of gluten. Alpha-gliadins are encoded by a large multigene family and amino acid variation in the CD epitopes is known to influence the immunogenicity of individual gene family members. Current commercial methods of gluten detection are unable to distinguish between immunogenic and non-immunogenic CD epitope variants and thus to accurately quantify the overall CD epitope load of a given wheat variety. Such quantification is indispensable for correct selection of wheat varieties with low potential to cause CD. RESULTS: A 454 RNA-amplicon sequencing method was developed for alpha-gliadin transcripts encompassing the three major CD epitopes and their variants. The method was used to screen developing grains on plants of 61 different durum wheat cultivars and accessions. A dedicated sequence analysis pipeline returned a total of 304 unique alpha-gliadin transcripts, corresponding to a total of 171 ‘unique deduced protein fragments’ of alpha-gliadins. The numbers of these fragments obtained in each plant were used to calculate quantitative and quantitative differences between the CD epitopes expressed in the endosperm of these wheat plants. A few plants showed a lower fraction of CD epitope-encoding alpha-gliadin transcripts, but none were free of CD epitopes. CONCLUSIONS: The dedicated 454 RNA-amplicon sequencing method enables 1) the grouping of wheat plants according to the genetic variation in alpha-gliadin transcripts, and 2) the screening for plants which are potentially less CD-immunogenic. The resulting alpha-gliadin sequence database will be useful as a reference in proteomics analysis regarding the immunogenic potential of mature wheat grains

Prospective comparison of microbial culture and polymerase chain reaction in the diagnosis of corneal ulcer.

PURPOSE: To compare polymerase chain reaction (PCR) to microbial culture for the detection and identification of bacterial and fungal pathogens in microbial keratitis. DESIGN: Prospective cohort study. METHODS: A total of 108 consecutive corneal ulcers were cultured and analyzed by PCR using pan-bacterial and pan-fungal primers. PCR products were cloned, sequenced, and compared to culture results using standard bioinformatics tools. RESULTS: Of the 108 samples, 56 were culture-positive, 25 for bacteria and 31 for fungi; 52 were culture-negative. After eliminating false-positive PCR products, 94 of 108 were positive by PCR, 37 for bacteria and 57 for fungi. Nineteen of 25 bacterial culture-positive samples were positive by PCR, and 29 of 31 samples culture-positive for fungi were positive by PCR. The majority of sequenced PCR products matched the positive culture results. Of the 52 culture-negative samples, 46 (88%) yielded pathogen deoxyribonucleic acid (DNA) PCR products, 18 bacterial and 28 fungal. These represented a variety of species, including at least three novel previously uncultured microbes. CONCLUSIONS: PCR detects microbial DNA in the majority of bacterial and fungal corneal ulcers, and identifies potentially pathogenic organisms in a high proportion of culture-negative cases. Yield and concordance with culture are higher for fungal than bacterial ulcers. Practical use of the technique is limited by artefactual amplification of nonpathogenic organisms. PCR may be used as an adjunct to culture to identify potential pathogens in microbial keratitis
