PENERAPAN METODE WEIGTHED LEAST SQUARE UNTUK MENGATASI HETEROSKEDASTISITAS PADA ANALISIS REGRESI LINEAR

Analisis regresi merupakan analisis statistik yang mempalajari bagaimana memodelkan regresi linear. Jika model regresi linear memenuhi uji asumsi klasik dengan metode OLS maka mempunyai sifat BLUE (Beast Linear Unbiased Estimator). Uji heteroskedastisitas,yaitu varian error pada setiap nilai variabel bebas bernilai tidak konstan. Akibat dari heteroskedastisitas yaitu nilai parameter yang diperoleh tetap tidak bias tetapi varian penaksir yang diperoleh menjadi tidak efisien, artinya uji hipotesis yang dilakukan tidak akan memberikan hasil yang baik (tidak valid) atau prediksi koefisien-koefisien populasinya akan keliru. Oleh karena itu untuk mengetahui apakah terdapat heteroskedastisitas dilakukan uji White. Karena terdapat heteroskedastisitas pada skripsi ini, maka harus dilakukan transformasi dengan metode kuadrat trkecil tertimbang (Weighted Least Square). Kata Kunci: Uji Asumsi Klasik, Weighted least Square, Uji White. Regression analysis is a statistical analysis that learn how to model linear regression. If a linear regression model meets the Classic Assumption Test by OLS method, it has the nature of BLUE (Best Linear Unbiased Estimator). Error variance at each independent variable value is not constant. It means that heteroskedasticity test is unfulfilled and the classical assumption is not met.The result of heteroskedastisitas is that the parameter value remains biased but variance estimator becomes inefficient. It means thata hypothesis test wouldn’t give good results (not valid) or predictions coefficients of the population would be mislead. Therefore, to know whether there are heteroskedasticity, White test is conducted. Because heteroskedasticity exists in this thesis, transformation with weighted least squares method (Weighted Least Square) must be carried out.

EFEK ANTI INFLAMASI KITOSAN DARI CANGKANG UDANG PANTAI TRISIK PADA TIKUS MODEL RHEUMATOID ARTHRITIS

This research was conducted to investigate the effect of chitosan as anti-inflammatory in rheumatoid arthritic in reduction of paw edema using plethysmometer. Chitosan was isolated from the shrimp shell on the Trisik Coastal were administered orally on 17-32th day with CMC 0,5%. This research using repeated measure design. To evaluate anti-inflammatory effect of the suspension, an arthritic rats model was developed using Complete Freund`s Adjuvant (CFA) on 1-16th day. In addition, the research was divided into 5 groups (n=6) including normal control groups, positive control groups, negative control groups, 1 group were treated by chitosan suspension at 50 mg/200 gram BW doses and the other group were treated by chitosan suspension at 100 mg/200 gram BW doses. The reduction of paw edema were determined every 3 day after 17th days then analyzed using general linear repeated measure test (p<0,05). The results showed that paw edema of arthritic rats were evidently decreased by chitosan suspension at 100 mg/200 gram BW doses (142,66%) better than chitosan suspension  at 50 mg/200 gram BW doses (117,23%).

Analisis Faktor Konfirmasi Indeks Pembangunan Manusia Indonesia Tahun 2019-2020

The Human Development Index (IPM) is one of the development target indicators that is very important to pay attention to its development, because it is one of the main performance measurement indicators for Regional Incentive Funds (DID) in encouraging community welfare improvements. In 2020, Indonesia's HDI percentage slowed down by 0.03 percent. This research aims to examine the dimensions that need to be developed so that Indonesia's HDI achievements continue to increase. This descriptive and verification research uses a quantitative approach. Secondary data collected in this study were analyzed using confirmatory factor analysis. The results state that the dimension of a decent standard of living has the strongest contribution to HDI achievements. Another result is that Papua is a province with the lowest standard of living in Indonesia which is reflected in its per capita expenditure. Several factors contribute to the low standard of living in the province of Papua, namely the high unemployment rate and poverty rate
