Abstract

Cholesterol in the body is divided into three parts, namely Low Density Lipoprotein (LDL) High Density Lipoprotein (HDL) and Triglycerides. Excessive cholesterol in the blood can cause hypercholesterolemia. The Simargaolgaol plant (Aglaonema modestum Schott ex Engl) is one of the plants that people use as traditional medicine to cure various types of diseases. This study aims to analyze the effect of administering simargaolgaol leaf extract on reducing cholesterol levels in male Wistar rats fed a high-fat diet. This study used a Completely Randomized Design (CRD) consisting of 6 groups, namely K0+ (Normal Group), K0- (Negative Control), K+ (Positive Control given simvastatin), varying doses 100 mg/KgBW, 200 mg/KgBW, 300mg/KgBW. The data obtained was analyzed using One way Anova statistical analysis with SPSS for Windows software. The data that has been analyzed has a significant value of p<0.05, which means that administration of ethanol extract of simargaolgaol leaves (Aglaonema modestum Schott ex Engl) shows an effect on reducing cholesterol in the blood. The conclusion of this research is that the ethanol extract of simargaolgaol (Aglaonema modestum Schott ex Engl) leaves has anti-cholesterol activity at a minimum dose of 300 mg/KgBW.

Abstract

This study aims to determine the learning of the Project Based Learning (PjBL) Model assisted by KOKAMI media (Kotak dan Kartu Misteri) on learning outcomes, learning motivation, and the significance between learning outcomes and motivation in chemical equilibrium materials at SMA Negeri 17 Medan. The sample population of all students in grade XI and as a random sample was taken from two classes, namely class XI B as an experimental class and XI C as a control class. The initial learning was carried out in the same pre-test, then learning was carried out for the control class (using the conventional model without KOKAMI media) while the experimental class (using the PjBL model with the help of KOKAMI media). The results data were analyzed using normality, homogeneity, and linearity tests. The hypothesis was tested by simple linear regression, independent t-test, and correlation test. The average pre-test score of the experimental class was 34,00  8,17 the control class was 33,14  6,57 post-test (89.71  3.60 ; 79.57 6.36), with a higher N-Gain value (0.84  0.065 ; 0.69  0.016 ). The results of the simple linear regression test showed a significance value of 0.000 ≤ (α = 0.005) with an average learning motivation of 87.25 (high category), so that Ha was accepted. The t-test shows the value of sig. 0.000 ≤ (α = 0.005), and the third hypothesis test showed sig. 0.001 ≤ (α = 0.005), indicating a significant relationship between learning outcomes and learning motivation
