Abstract

The aim of this study is to know the effectiveness of learning based on Web at Number Theory lesson at IKIP PGRI Semarang. The implementation is focused at FPMIPA IKIP PGRI Semarang in fifth semester of mathematics education students which contain of 9 classes. Sampling technique in this study use convenience sampling procedure, where as the experimental is 5B and 5A as the control class and 5G as a class test. Independent variable of this research is the activity of student and learning result as dependent variable. The Data is obtained through observation and tests then we analyze by t test and regression test.. The results showed that implementation of learning achieve effective with characterized by: a) Mean of student learning result greater than KKM = 75, and in classical is more than 85% of students achieve point at 75. b) Effect of activity on the results of study is means that the active variable (X) gives a positive effect on learning result (Y). The value of the effect of creativity on learning result can be seen by R value in the table of Summary Model 0.867 = 86.7%. The Value indicates that the creativity of students affect learning result at 86.7%. c) The Mean of experimental class is 80.94 and 62.60 for the control class, so the class of experiments significantly better than the the control class. Based on the above explanation we conclude that learning based on web at Number Theory in Semarang PGRI IKIP is effective.

Abstract

This paper presents the modeling of the amount of sugar and molasses production in Pabrik Gula Candi Baru Sidoarjo (PGCBS), East Java, by using multivariate mixedlinear models. Estimation of parameters will be done by using maximum likelihood coupled with restricted maximum likelihood methods. The amount of sugar and molasses products which have strong linear correlation, will be set as responses and are supposed to be affected by seven fixed effect variables and four random effect variables. This paper demonstrates that the seven fixed effect variables and only one random effect variable have significant influence on a single response. In the multivariate response modeling, however, all of variables fail to explain the variability of these two responses simultaneously. It is due to the factors matrix has no full rank. As a result, the model response of molasses can be explained by using a model of the amount of sugar obtained.

Abstract

Nonlinear time series are time series that are not stable due to a sudden jump. Nonlinear time series often found in financial data. Threshold Autoregressive (TAR) modeling is a time series modeling with a segmented autoregressive (AR)’s model such that among different regimes may have different AR model. This research studied how to obtain the Ordinary Least Square (OLS) estimator for TAR model and examine signification the OLS’s estimator by using t test. This research also studied the other stages of TAR modeling, which are nonlinearity test using Tsay test, TAR model identification by using arranged AR approach and Akaike’s Information Criterion (AIC), and diagnostic test by examining the white noise properties and normality test on the residuals. As an illustration, the TAR modeling was applied on weekly data of rupiah exchange rate against US dollar for period October 4th 2004 to November 7th 2011. The result show that the best TAR model for the data is TAR with threshold value .

Abstract

Calendar variation method is a technique that combines ARIMA modeling and regression modeling. Calendar variation is a cyclical pattern with varying periods due to the different calendar date position for each year. There are two types of calendar variation, trading day variation and holiday variation. In this research, modeling of time series with holiday variation was studied and modification of the modeling was developed for the case of holiday effect due to Eid’s day occur. The case study was conducted to the data of train passenger number at DAOP V Purwokerto. It was found that the last model for the underlying data was the regression model with the residual following seasonal ARIMA (1,1,1)(0,0,1)12 without constant parameter.

Population in the study were all students of third semester of mathematics education IKIP PGRI Semarang. This study is a research and development. In media studies e-learning development is carried out with 4 (four) stages, namely (a) a preliminary analysis, (b) Design, (c) Evaluation, (d) Revised. Processing the data using descriptive qualitative data analysis techniques. Corresponding results of questionnaires about the development of e-learning in the obtained value sig = 0.00 and R = 0,541, which means it affects the motivation for 54.1% of the student learning outcomes. Gained an average of better learning outcomes between the experimental class at 84.27 compared with 80.05 for the control class. The results obtained from the e-learning instructional media are valid for independent study students on computing courses I according to developmental theory Akker and student learning outcomes.

Abstract

In the real cases, we are frequently faced the problem in which two or more dependent variables are observed at several values of the independent variables, such as at multiple time points. Multi-response nonparametric regression model, especially smoothing spline model, provides powerful tools to model the function which represents association of among the variables. The problem is how to estimate nonparametric regression curve of the multi-response nonparametric regression model. The nonparametric regression curve can be estimated using spline estimator approach, that is by carrying out penalized weighted least-squares optimation. Therefore, we need a covariance matrix which will be used as a weight of the optimation. In this paper, we determine the construction of covariance matrix for both equal and unequal of correlations cases. The results show that the covariance matrices have quite similar construction of diagonal elements but the elements outside the diagonal have very different construction that depend on the construction of the Jordan matrix.

Abstract

This research aims to improve mathematics learning achievement of first semester student majoring biology at IKIP PGRI Semarang using mathematics learning based on constructivism in basic mathematics courses. This type of study is a research of Quasy Experimental. The population is the first semester of students majoring in biology education IKIP PGRI Semarang which consists of five classes. By random sampling technique we choose two classes, class 1A as a class experiment and class 1E as a control class. Variables in this research are the process skills (X) as the independent variable and learning achievement (Y) as the dependent variable. Data collection had been done by observation and learning achievement tests and for analyzing by comparison and influence tests. The results showed that completeness test has average 70.20 . It means that completeness had been and there is a achievement difference between the experimental class and control class. Beside that, we find that variable of process skill has a positive effect to the learning achievement by regression equation and the effect is 20.3%. It is shown that learning at experiment class is effective.

Abstract

Multivariate Cox proportional hazard models have ratio property, that is the ratio of hazard functions for two individuals with covariate vectors z1 and z2 are constant (time independent). In this study we talk about estimation of prameters on multivariate Cox model by using Maximum Partial Likelihood Estimation (MPLE) method. To determine the appropriate estimators that maximize the ln-partial likelihood function, after a score vector and a Hessian matrix are found, numerical iteration methods are applied. In this case, we use a Newton Raphson method. This numerical method is used since the solutions of the equation system of the score vector after setting it equal to zero vector are not closed form. Considering the studies about multivariate Cox model are limited, including the parameter estimation methods, but the methods are urgently needed by some fields of study related such as economics, engineering and medical sciences. For this reasons, the goal of this study is designed to develop parameter estimation methods from univariate to multivariate cases.
