Abstract

ABSTRAK  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 terkecil tertimbang (Weighted Least Square).Kata Kunci: Uji Asumsi Klasik, Weighted least Square, Uji White. ABSTRACT  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.Keyword: Classic Assumption Test, Weighted least Square, White Test.

Abstract

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%). In conclusion, the chitosan from shrimp shell of Trisik coastal is found to be effective as anti-inflammatory in rheumatoid arthritic rats model.

Abstract

This study aims to determine how the effect of compensation and work environment on discipline of employees at PT. Altrak 1978 Branch Pekanbaru. As for the population in this study were employees of PT. Altrak 1978 Branch Pekanbaru 2015 as many as 87 people. Meanwhile, all the population are the respondent of this research, so the method is cencus. Analysis of the data using quantitative analysis tools that multiple linear regression with SPSS version 18.00. From the testing that has been done, simultaneous test (F-test) showed that compensation and work environment simultaneously have significant effect on the discipline of employees, while the partial test (t-test) showed that compensation and work environment partially significant effect on work discipline employee. Companies should pay more attention to discipline the employee to work with the maximum as leaders must have the courage to act decisively to apply penalties to subordinates who violate the rules. If there are employees who do not comply with work rules, the company reserves the right to give strict punishment for those employees. Sanctions here could be a suspension or dismissal of employees when the employee is no longer care for work discipline and reprimand from the boss.Keyword : Compensation, Work Environment and Discipline.

Abstract

Cayenne pepper is a perishable product. One of the damages that can cause spoilage in cayenne pepper is microorganisms. This study examines the quality change of cayenne pepper during storage. The research design employed in this study was a complete factorial randomized design with two factors: voltage levels, comprising 8,00, 9,20, and 10,40 kV, and treatment times of 20, 40, and 60 seconds. Cold plasma effectively reduced microorganisms and did not significantly affect weight loss and color value during storage. Plasma voltage levels significantly influenced hardness, total dissolved solids, and vitamin C content. The treatment with cold plasma at 9,20 kV for 40 seconds was considered the most effective in preserving chili quality. Cold plasma reduced weight loss and maintained chili color, hardness, total dissolved solids, and vitamin C content. The total plate count of cayenne pepper with cold plasma at 9,20 kV for 40 seconds is 6,55 x 105 colony/g. Cold plasma extended the shelf life of cayenne pepper for up to 12 days.

Abstract

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.

Abstract

Piper porphyrophyllum or known as tiger’s betel, is a medicinal plant of the Piper genus that is quite widespread in Indonesia, especially on Java, Sumatra, and Kalimantan island. Tiger’s betel is widely used traditionally to treat headaches, bone pain, chest tightness, skin diseases, relieve inflammation, and diabetes mellitus. This study aims to determine the type of secondary metabolite compounds contained in the ethyl acetate fraction of tiger’s betel and determine its antidiabetic activity. Determination of the type of compound is conducted by phytochemical screening by a qualitative test using various reagents to identify flavonoids, phenolics, saponins, triterpenoids, steroids, alkaloids, and coumarins. The antidiabetic assay was carried out by inhibiting α-glucosidase activity and the results were reported as IC50 values. The ethyl acetate fraction of tiger’s betel positively contains alkaloids, flavonoids, and phenolics. The antidiabetic activity is classified as very strong, with an IC50 value of 14.06 µg/mL.
