Abstract

The aim of the research is to know whether the result of school examination in-fluences the result of national examination significantly. Observation data was taken from the third year science students of SMUN1 Limboto Gorontalo Regency Gorontalo Pro-vince. The best method to get regression model with unbias estimator is used the least square was done by using classical assumption examination, those are normal, multi-colinier an correlation ones. The result showed that national examination data, mean of Raport, Tryout, School examination marks and Practice examination, fulfill this assum-ption. Base on analysis data, it that in partially, UAN grades are influenced by: Raport grades with MSE=0,004 and R2=45.9%, Tryout grade with MSE= 0.09931 and R2= 59.3%, School grade with MSE=0.235691 and R2=5.8% and Practical grade with MSE=0.09931 dan R2 = 59.3%. Simultantly, UAN grades are influence by: Raport grade= –0.384, Tryout grade=0.848, School grades = –0.303 and Practical grade=0.082. Based on beta coefficient, it can be concluded that mean variable of tryout mark has the most dominant influences to national examination mark. The surtable mathematics model can be stated as Ŷ=4,985+ 0,182(x1)+0,370(x2)–0,261(x3)–0,280(x4)+0,376(lag_Y).

Abstract

The aim of this study was to know the a mount of production prosess ability at PT Ranjang Gajah Tekstil, by data of defect production. The observation based on secondary data, whereas the analysis approach used was p-control graphic with control chart.By using p-control graphic, it seemed that there was observation out of control caused by uncontrol production. Through some improvements, the result which was abtained showed that production process ability caused by lusi movement decreasing 0,163%, pakan movement decreasing 0,259%, ngapuk decreasing 0,054% , and sobek decreasing 0,041%.It was found that the special cause of defect data of lusi movement were, one the 21st observation cause of rusty sisir the 33rd, 34th adn 37th ones cause of broken fork gird. For pakan movement defects found that on the 1st, 2nd, 3rd, 16th, 17th, and 52nd ones caused by loose shuttle, on the 4th and 5th ones cause of less good shuttle replacement, and on the 6th one cause of sisir kecak. Therefore the result of this study used by the company in order to do improvements and be able to observe process ability continually in order to be stable.

Abstract

In order to give more complete information about stock exchange development to public, "Bursa Efek Jakarta" (BEJ) has spread out stockt value movement data through press and elec-tronic. From fifteen index data component available, the important indi-cator in stock value exchange is Daily Stock Value Index (IHSG) and Trade Volume. Base on data taken by researcher through website of Jakarta Stock Exchange (JSX) on data menu trade at http://www.jsx.co.id, it was obtained data exchange pattern of IHSG and Trade Volume for 358 days and the researcher extrapolated the datum to the next time (predict the next 90 datum) The result of analysis by using software Minitab v13 showed that the mode of quadratic trend pattern is very suitable for both datum. Trend equation of IHSG data is: Yt = 1085,53-0,581334t+4,21E-03t2 and trade volume is: Yt =0,972451-1,50E-04t+3,93E-07t2. Forecasts value for next 90 datum is useful for business user in long term. The pattern of both datum is stationary in the first difference. So Box-Jenkins mode can be formed for IHSG data is ARIMA(1,0,0), with the first mode:Zt = 0,0838 Zt-1 + at; at~indN(0,0.9296); ARIMA(1,0,1) with the first mode: Zt = -0,10498-0,2482Zt-1+at-0,3399at-1; at~ind N(0,0.84843) and ARIMA(1,0,0) with the first mode: Zt = -0,4273Zt-1+at;at~ind N(0,0.6046). With the same way it is obtained Box-jenkins mode for Trade Volume data : ARIMA(1,0,0) with the first mode: Zt= -0,4051Zt-1+at; at~ind N(0,32.0315), ARIMA(0,0,1) with the first mode:Zt = -4,73+at+0,7342at-1; at~ind N(0,6.0753) dan ARIMA(1,0,1) with the first mode: Zt = 3,9811-0,1706Zt-1+at+0,8230at-1­; at~ind N(0,23.04)

Abstract

The choice of prediction in time series sequence, which produced valid and acurate prediction value is the main problem in prediction method. The study of data used by researcher was taken form website of Jakarta Stock Exchange (JSX) on menu of trade data addressed at http://www.jsx.co.id. Significant indikator in Stock Exchange Movement were IHSG and Trade Volume. Index functioned as market trend indicator, so from the index number, we know trend of stock volume movement today and extrapolate in the future. The aions of this research were to predict data pattern of IHSG and trade volume by using smoothing model approach since the best estimstion choice just compared some values of MSE, MAD, MSD and value. The result of analys shows that smooth mode of linear trend is very suitable for both datum. They are for IHSG and for Trade Volume. And then Box-Jenkins mode can be formed for IHSG data is ARIMA(1,0,0) and ARIMA(1,0,1) where as for Trade Volume data is ARIMA(0,0,1), ARIMA(1,0,0) and ARIMA(1,0,1).
