Abstract

Their self-efficacy or self-confidence, is related to active involvement in solving problems. This belief encourages students to be actively involved in learning and overcoming academic challenges. The solution offered is the application of the Problem Based Learning (PBL) learning model assisted by interactive website-based media. This interactive model and media allow students to be actively involved in learning, to improve their problem-solving skills and strengthen their self-efficacy. The purpose of this study was to analyze the application of the Problem Based Learning (PBL) model assisted by interactive media on improving problem-solving skills and self-efficacy of students. This research method uses a quantitative R&D approach. The population in this study was 143 students, with a sample of 72 students in class XI of SMAN 4 Banda Aceh. Data collection in this study used several techniques, namely the test technique (Problem Solving Skills essay questions) and non-test techniques (Self-Efficacy questionnaire). Based on the research results, it is known that there is an influence of the application of the PBL model assisted by interactive media on improving students' problem-solving skills on the reproductive system material at SMAN 4 Banda Aceh and there is a positive relationship between self-efficacy and students' problem-solving skills through the application of the PBL model assisted by media on the reproductive system material at SMAN 4 Banda Aceh.

Abstract

Oxidative stress plays a crucial role in the development of various degenerative diseases, highlighting the need for safe and effective natural antioxidants. This study aimed to evaluate the antioxidant activity of saga seed (Adenanthera pavonina) extracts using DPPH and ABTS assays and to examine their relationship with total phenolic content (TPC). An in vitro experimental study with a quantitative approach was conducted. The extraction process was performed using maceration with 95% methanol and 95% ethanol as solvents. Antioxidant activity was determined based on IC₅₀ values, while TPC was analyzed using the Folin–Ciocalteu method and expressed as mg gallic acid equivalents (GAE)/g extract. The results demonstrated that the methanolic extract exhibited stronger antioxidant activity (IC₅₀ DPPH = 86.43 ppm; IC₅₀ ABTS = 54.07 ppm) compared to the ethanolic extract (IC₅₀ DPPH = 99.11 ppm; IC₅₀ ABTS = 72.41 ppm). The methanolic extract also showed a higher TPC value (319.90 mg GAE/g) than the ethanolic extract (194.33 mg GAE/g).

Abstract

This learning is designed to facilitate the individual learning needs of different learners by integrating social and emotional awareness. The purpose of this research to improving the motivation and learning outcomes. This research uses the development of the ADDIE model. The results show an increase in student learning outcomes and student learning motivation in class XI IA2 SMA Negeri 1 Krueng Barona Jaya. Student learning outcomes with paired sample T-test test obtained sig. (2-tailed) 0.00 <0.05. Is a significant difference between biology learning outcomes in pre-test and post-test data. Students' responses through plasma membranes in class XI IA2 SMA Negeri 1 Krueng Barona Jaya is Very Good, with a percentage of 91.91%.

Abstract

Teaching at The Right Level (TaRL), is a learning approach by orienting learners to carry out learning. The purpose of this study is to design and implement learning by applying the Teaching at the Right Level (TaRL) approach and applying the Culturally Responsive Teaching (CBT) approach that connects the cultural background of learners with material content. The methods carried out in this study include the preparation stage of compiling assessments, designing, preparing modules, the implementation stage, the evaluation stage and follow-up. The results of this study indicate that the application of Teaching at the right Level (TaRL) and Culturally Responsive Teaching (CRT) approaches is very appropriate to be used in the learning process to meet the diverse ability levels of learners, material content that is associated with the culture of learners raises learners' awareness of their own cultural identity. The use of digital learning media motivates learners in learning because there is an element of novelty and in accordance with technological developments.

Abstract

The goal of this study is to increase students' CTS and CS about quantity and unit material using ethnoscience-based inquiry learning. The study utilized a non-equivalent control group design with two classes: experimental and control. The sample in this study were students of class X IPA 7 and X IPA 8, who were chosen using purposive sampling procedures. The research sample comprised 71 students. The research data was gathered using 15 multiple-choice questions, a CTS questionnaire, and a CS questionnaire. Normality, homogeneity, the t-test, and correlation tests were employed to analyze the data. Based on the research findings, students' CTS and CS rose in the experimental class, with N-gain values of 0.71 (high) and 0.60 (medium). The experimental and control courses showed significant differences in students' CTS and CS outcomes (Sig. < 0.05). Aside from that, there is a very strong correlation between students' CTS and CS results in learning, with r = 0.938. It may be concluded that using an ethnoscience-based inquiry paradigm can help students enhance their CTS and CS. Thus, it is possible to infer that ethnoscience-based inquiry learning may increase students' CTS and students' CS. There is a very strong correlation between CTS and students' CS.
