Abstract

The Influence of Learning Models and Mathematical Abilities on Student Learning Outcomes on the Subject of Chemical Equilibrium. This research aims to determine the influence of learning models, mathematical abilities and the interaction between learning models and mathematical abilities on student learning outcomes on the subject of chemical equilibrium.  The research population was all 10 class XI students of SMA Negeri 1 Percut Sei Tuan. Samples were taken in two stages, namely: first, 2 class samples were taken randomly. In the second stage, each class was divided into 2 groups, namely a high mathematics ability group consisting of 10 people and a low mathematics ability group of 10 people so that the total sample of students used was 40 people. This research used a 2 x 2 complete random factorial design. There were two factors tested, namely factor A: Learning Model which consisted of 2 levels, namely A1 = Problem Based Learning and A2 = Discovery Learning, factor B: Students' mathematical abilities which consisted of 2 levels namely B1 = high mathematical ability and B2 = low mathematical ability. Based on hypothesis testing at a significance level of α = 0.05, it was found that Fhit (A) = 26.61 and Fhit (B) = 10.53 while Ftable = 4.11. Thus, Fhit (A) > Ftable, which means that there is an influence of the learning model on student learning outcomes on the subject of chemical equilibrium. Likewise, Fhit (B) > Ftable means that there is an influence of mathematical ability on student learning outcomes. Furthermore, we obtained Fhit (AB) > Ftable or 7.15 > 4.11, meaning that there is an interaction between the learning model and mathematical abilities on student learning outcomes on the subject of chemical equilibrium.Keywords: Problem-Based Learning, Discovery Learning, Mathematics Ability, Learning Outcomes, Chemical Equilibrium DOI: 10.23960/jppk.v13i2.30259

Abstract

This study aims to determine whether giving beluntas leaf extract has an effect on albumin levels and total serum protein in white mice induced with E.coli bacteria. RAL was used consisting of 3 treatments and 5 replications. White mice were induced and then given 0.5 ml of extract at a dose of 0.00 mg/kgBW; 300 mg/kgBW; and 600 mg/kgBB. The results showed that administration of the extract had a very significant effect on albumin levels and total serum protein in white mice. Giving the extract at a dose of 600 mg/kgBW gave the highest serum albumin levels but gave the lowest total protein levels. Giving the extract at a dose of 0.00 mg/kgBB; 300 mg/kgBW; and 600mg/kgBW in white mice were induced to give average albumin levels of 2,706 g/dL respectively; 2.844 g/dL; 4.454 g/dL and the mean total serum protein levels were 8.51 g/dL respectively; 8.86 g/dL; 8.8 g/dL.
