Abstract

The problem in this study is the low learning outcomes of students on Digital Simulation subjects in SMK N 3 Pariaman. This study aims to determine the effect of learning outcomes by using Active Learning model Practice Rehearsal Pairs type with direct learning models on subjects Digital Simulation class X TKJ odd semester SMK N 3 Pariaman Year Teaching 2017/2018. This type of research uses the Quasi Eksperimental design. Sampling using Probability Sampling technique, The sample of research is class X TKJ B as experiment class using Active Learning model of Practice Rehearsal Pairs type and class X TKJ A as control class using direct learning model. Data collection technique from post-test in experiment and control class, then analyzed for homogeneity test, normality test and hypothesis test. From the experimental class research results obtained an average value of 86.88, while the control class gets an average value of 78.28. Result of hypothesis calculation at significant level α = 0,05 got titung> ttable that is 3,780> 1,678, because big tcount of ttable, hil n hypothesis (H0) rejected and alternative hypothesis (Ha) accepted. Can be concluded mean at the real level, this research shows that, there is influence of student learning outcomes between the use of Active Learning model of Practice Rehearsal Pairs type with direct learning model on Digital Simulation subjects of class X TKJ in SMK N 3 Pariaman. The use of Practice Rehearsal Pairs model has a significant influence on the improvement of Digital Simulation learning outcomes.Keywords: Active Learning, Practice Rehearsal Pairs, Learning Outcomes, Digital Simulation

Abstract

The presence of Chromium (Cr) in electroplating wastewater is a major environmental problem. That toxicity and non-biodegradable where should be eliminated from water. Chlorella sp immobilized in calcium alginate is one of technology that can reduce the concentration of Cr in the electroplating wastewater quickly and without produced sludge. The data were analyzed using AAS on variation cell density in alga beads (0; 1,53x108; 1,76x107; 1,54x106 cells / beads) and contact time (0, 12, 24, 36 and 48 hours). The result showed that the highest removal efficiency of Cr occured at cell density 1,54x106 cells/beads and contact time 48 hours with efficiency of 52,04%.Keywords: biosorption, microalgae, Chlorella sp, cell density, contact time, Cr, electroplating wastewater

Abstract

The objectives of this study were to find out on the topic of two dimentional figure: (1) which was better between Example Non Example, talking stick or Direct learning that produce learning achievement; (2) which one had better learning achievement between students with high, medium or low categories of independency learning; (3) at each category of independency learning, which was better between Example Non Example, talking stick or Direct learning that produce learning achievement; and (4) at each model pembelajaran, which one had better learning achievement between students with high, medium or low categories of independency learning. This study was a quasi-experimental with 3´3 factorial design. The population was all of students in seventh grade of State Junior High School in Pemalang Regency on Academic Year 2019/2020. The samples were taken by using a stratified cluster random sampling technique. The samples was students in seventh grade of SMP Negeri 1 Randudongkal, Moga and Pulosari. The instrument of this study were independency learning questionnaire and learning achievement test. The questionnaire tryout included content validity, internal consistency and reliability, and the test tryout included content validity, difficulty level, discrimination power, and reliability. Before the experiment was done, the balance of prior knowledge was examined by using unbalanced one way anova test. The hypothesis test used unbalanced two ways anova. Test requirements included normality test used Lilliefors method and the homogeneity test used the Bartlett test. The results of the study were as follows: (1) the Example Non Example model produce the learning achievement better than the Talking Stick and direct learning, the Talking Stick model give the same learning achievement as the direct learning; (2) the high and medium categories of independency learning have the same learning achievement, and both category of independency learning have better learning achievement from low categories of independency learning; (3) at each categories of independency learning, the Example Non Example model produce the learning achievement better than the Talking Stick and direct learning, the Talking Stick give the same learning achievement as the direct learning; and (4) at each models, the high and medium categories of independency learning have the same learning achievement, and both of category of independency learning style have better learning achievement from low categories of independency learning.
