Comparison of Student Achievement in Teaching Analytic Geometry of Planes and Space Using GeoGebra and PowerPoint Media at STKIP Abdi Wacana in Semester VI of the Academic Year 2021/2022 in Wamena

The research examines the comparison of student learning achievement on the topic of analytic geometry of planes and spaces, which is taught using two different learning media, namely GeoGebra and PowerPoint media. This experimental research used two different experimental classes, each consisting of 14 and 15 students. The research design used is a counterbalance design because even though students' initial knowledge is homogeneous, there are still many other variables that affect the process and learning outcomes, which cannot be controlled and are not homogeneous. The research data used were pre-test and post-test scores for each treatment, which were then processed to obtain normalized gain data. Data processing was carried out using SPSS software and was preceded by an analysis of homogeneity tests and normality tests. Based on the Wilcoxon Signed Test, it is clear that the two learning media are able to improve student learning outcomes. The paired samples test is used to compare the learning outcomes of the two learning models. The results showed that learning using GeoGebra media gave higher learning outcomes compared to using PowerPoint media. The average normalized gain difference between the two media is 0.34

PENDUGAAN PERSENTASE KEJADIAN GIZI BURUK DI JAWA TIMUR MENGGUNAKAN MODEL REGRESI TERBOBOTI GEOGRAFIS (RTG)

Provinsi Jawa Timur memiliki karakeristik wilayah yang berbeda. Perbedaan karakteristik wilayah dapat berupa masalah sosial, ekonomi, budaya, pola asuh, pendidikan, dan lingkungan, sehingga dapat menyebabkan adanya perbedaan kejadian balita gizi buruk antara wilayah satu dengan wilayah lainnya. Penderita gizi buruk dari satu wilayah diduga dipengaruhi oleh wilayah sekitarnya.  Oleh karena itu, diperlukan suatu  pemodelan statistik dengan memperhitungkan faktor spasial. Metode statistik yang dapat digunakan untuk menganalisis data dengan memperhitungkan faktor spasial adalah Regresi Terboboti Geografis (RTG). Penelitian ini bertujuan untuk menentukan model kejadian gizi buruk di Provinsi Jawa Timur menggunakan model RTG dengan pembobot kernel adaptif kuadrat ganda dan membandingkan model RTG dengan model regresi linear konvensional.Data yang digunakan adalah data sekunder dari survei sosial ekonomi nasional (SUSENAS) dan Riset Kesehatan Dasar (RISKESDA) 2010 pada 38 kabupaten/kota di Jawa Timur.Pendugaan parameter model dilakukan dengan menggunakan metode Weighted Least Squares (WLS) yaitu dengan memberikan pembobot  yang berbeda untuk setiap wilayah.  Hasil penelitian diperoleh terdapat  38 model kejadian gizi buruk yang berbeda untuk setiap kab/kota di Jawa Timur.   Model RTG dengan menggunakan pembobot fungsi kernel kuadrat ganda lebih baik digunakan untuk memodelkan kejadian gizi buruk di Jawa Timurdibandingkan dengan regresi linear konvensional berdasarkan kriteria kebaikan model yaitu R-square, Mean Square Error (MSE) dan Akaike Information Criterion (AIC)

Estimation of Percentage on Malnutrition Occurrences in East Java using Geographically Weighted Regression Model

The Province of East Java has its own characteristics that differentiate it from any other regions. Dissimilarities in characteristics of a region may encompass issues such as social, economic, cultural, parenting, education, and the environment, so as to cause the difference in case of severe under nutrition between one region to another. Sufferers of malnutrition in one region may be linked and influenced by the surrounding regions. Therefore, we need a statistical modeling that is able to take into account the spatial factor. Statistical methods that can be used to analyze the data and also takes into account the spatial factor are the Geographically Weighted Regression (GWR). This study is aimed to determine the case of malnutrition models in East Java Province using GWR model with kernel adaptive bi-square weighting and comparing it to the conventional linear regression model.  The data used in the study are secondary data obtained from the National Socio-Economic Survey and Basic Health Research (2010) conducted in 38 districts in East Java. Estimation is done by using the Weighted Least Squares method that provides different weighting values to each region. The result showed that there are 38 models of the malnutrition case that is different for each district in East Java. The GWR model with bi-square kernel weighting function is better in modelling the case of malnutrition in East Java compared to the conventional linear regression models that are based on the criteria of goodness that is the R-square, Mean Square Error and the Akaike Information Criterion
