    The purpose of this research is to analyzed the ratio of company performance measured by accounting-based measurementss with ROA and ROE and company performance measured by market-based measurements with MBV and MVA between ISO 9001 certified and non-certified companies in manufacturing sector listed on the Indonesia Stock Exchange during 2014-2016. Data analysis techniques used are different test with Mann-Whitney. The result of the research shows that there are significant differences to the performance of the organization by accounting-based measurements between ISO 9001 certified and non-certified companies. By market-based measurements, there are significant performance differences in the MBV variables but there is no performance difference in the MVA variables between ISO 9001 certified and non certified companies

    Comparative Analysis of Direct and Indirect 131I Measurement Methods From the Stack to Outdoor

    The radioisotope production facility at PUSPIPTEK Serpong produces and processes 131I that can disperse to the settlements (community) and the environment around the Serpong Nuclear Area (SNA). 131I is produced routinely for medical uses in hospitals and pharmacies, for both domestic uses and export. 131I is a beta and gamma emitting radioactive material and can cause thyroid cancer. The problem was that there was so far no research and in-depth assessment of the aerial dispersion of 131I radioactivity emitted from the radioisotope production stack to the environment at actual conditions. The research was conducted through simultaneous measurement of 131I radioactivity in the stack of the 131I radioisotope production facility, Serpong, and outdoor in house courtyards around SNA in normal condition (no accident) based on the variations of the distance and wind direction. Direct measurements were carried out with a portable in-situ NaI(Tl) detector at outdoor, and with a LaBr3 detector in the stack. Indirect measurements were carried out by using charcoal filter and vacuum pump in the stack and outdoor. The direct measurement method has many advantages over the indirect measurement. The direct measurement method was found to be more accurate, less expensive, easier to operate, needing just one operator in its implementation, portable, and can be operated continuously and for long durations. The overall activity concentrations of 131I on average obtained by either direct or indirect method were still below the upper limit of 131I activity concentration in the air (530 Bq/m3) stipulated by the Regulation of the Chairman of BAPETEN (Perka BAPETEN) No. 7/2013

    The global financial crisis that occurred in 2008, the opening of free trade of Southeast Asia (MEA). As well as the use of new methods in the assessment of the health of the bank directly or indirectly impact on the health of the banking performance changes. This study aims to determine the differences between the health levels of government-owned banks and national enterprises listed on the Indonesia Stock Exchange in 2013 and 2014. An assessment of the soundness of banks is an assessment of the factors RGEC the risk profile (risk profile), corporate governance good (good corporate governance), earnings (earnings), and capital (capital). Banks are becoming a sample of 27 banks of the population of 41 banks with purposive sampling method. The data analysis technique used is the Independent sample T-test.The results showed that the condition of banks in terms of risk profile, corporate governance and capital in a healthy state with PK-II both in 2013 and 2014. In terms of profitability shows that state-owned banks in better shape with a very healthy predicate either in 2013 or 2014 . Meanwhile, a national privately owned banks in the state are healthy enough to PK-III both in 2013 and 2014. in addition, the results also showed that there were no differences between the health levels of government-owned banks and national private sector. Partially factor risk profile, corporate governance and capital did not show any significance between the government and private banks nationwide. While the earnings factor show opposite results

    Community detection algorithms: a comparative analysis

    Uncovering the community structure exhibited by real networks is a crucial step towards an understanding of complex systems that goes beyond the local organization of their constituents. Many algorithms have been proposed so far, but none of them has been subjected to strict tests to evaluate their performance. Most of the sporadic tests performed so far involved small networks with known community structure and/or artificial graphs with a simplified structure, which is very uncommon in real systems. Here we test several methods against a recently introduced class of benchmark graphs, with heterogeneous distributions of degree and community size. The methods are also tested against the benchmark by Girvan and Newman and on random graphs. As a result of our analysis, three recent algorithms introduced by Rosvall and Bergstrom, Blondel et al. and Ronhovde and Nussinov, respectively, have an excellent performance, with the additional advantage of low computational complexity, which enables one to analyze large systems.Comment: 12 pages, 8 figures.
