Abstract

Hypercholesterolemic, a condition characterized by excess cholesterol content, can lead to coronary heart disease, atherosclerosis, and high-risk heart tissue degeneration. Current drugs, like simvastatin and pravastatin, focus on lowering cholesterol levels without addressing tissue degeneration. This study aimed to determine the effectiveness of sidempuan salacca vinegar in improving cardiac tissue degeneration in hypercholesterolemic mice. The experimental research involved two groups, the treatment group given different doses of sidempuan salacca vinegar and the control group. Histopathological observations showed improvement in cardiac tissue degeneration in hypercholesterolemic mice after treatment with salacca vinegar. The administration of salacca vinegar could serve as a reference for developing alternative hypercholesterolemic drugs that address both cholesterol levels and heart degeneration.

Abstract

Critical thinking is one of the most essential skills to be developed in 21st-century education. However, many classroom activities still rely on conventional methods that fail to actively engage students. This study aimed to investigate the effect of integrating the Problem-Based Learning (PBL) model with Socio-Scientific Issues (SSI) on junior high school students’ critical thinking skills in the topics of ecology and biodiversity. A quasi-experimental method with a non-equivalent control group design was employed. The research subjects consisted of two eighth-grade classes at SMP Negeri 35 Padang: one class implemented the PBL-SSI model as the experimental group, while the other used conventional learning as the control group. Data were collected through pre-tests and post-tests and analyzed using the t-test. The results showed that before the intervention, students in both groups had comparable levels of critical thinking skills. However, after the intervention, the experimental group demonstrated a significant improvement (tcount = 7.234 > ttable = 2.005). Improvements were evident across six indicators of critical thinking, including information analysis, drawing conclusions, and evaluation. These findings indicate that the PBL-SSI model effectively enhances students’ critical thinking skills through meaningful, contextual, and applicable learning experiences. By incorporating real-life issues, this model encourages active student participation in discussion, problem-solving, and decision-making, thereby making the learning process more engaging and meaningful.

Abstract

Low student communication skills have been the cause of this research, which had an impact on learning outcomes because there had not been training on students' communication skills through the application of appropriate learning models. The learning process, which still uses conventional learning models, namely group discussions, has not made each student active and responsible for group assignments and has not trained communication skills in scientific arguments. Therefore, an appropriate learning model is needed, one of which is the Numbered Head Together (NHT) type cooperative learning model. The aim of the research is to determine the effect of implementing the NHT type cooperative learning model on the communication skills of SMPN 3 Tebo students. The research uses a Quasi-Experimental type of research with a Nonequivalent Control Group Design. The research began with a pretest in the experimental class and control class, then treatment was given to the experimental class, and at the end of the learning process, a posttest was given to both classes. Samples were taken using purposive sampling technique. The test instrument consists of 13 description questions. Data were analyzed using Microsoft Excel to carry out prerequisite tests and hypothesis tests on overall communication skills and each ability indicator. The results of the research showed that there was an increase in students' overall communication skills between before and after treatment. Through the Mann Whitney test with Zcount -5.32 and Ztabel 1.96 with the criterion that H0 is accepted if “Ztabel ≤ Zcount ≤ Ztabel, then Zcount -5.32 < -Ztabel -1.96, then H0 is rejected, and H1 is accepted. It can be concluded that there is a significant influence of implementing the Numbered Head Together type learning model on the communication skills of students at SMP Negeri 3 Tebo Regency.
