Abstract

This study aims to determine the application of the Problem Based Learning (PBL) model in improving student learning outcomes on energy change materials in class IVB MI Nahdlatul Ulama Ngingas, Waru, Sidoarjo. This study uses a Classroom Action Research (PTK) approach which consists of two cycles, with each cycle including planning, implementation, observation, and reflection. The data sources in this study include student pretest and posttest results, observations of learning activities, and interviews with students and teachers. The results of the study show that the application of the PBL model can significantly improve student learning outcomes. Before the implementation of PBL, only 50% of students achieved the Minimum Completeness Criteria (KKM), with an average class score of 65. After the implementation of the PBL model, as many as 85% of students achieved grades above the KKM, with the average grade increase to 78. In addition, students also show improvements in critical thinking skills and the ability to collaborate. Based on these findings, it can be concluded that the PBL model is effective in improving student learning outcomes on energy change materials, as well as helping students develop problem-solving and collaboration skills.

Abstract

The Independent Curriculum (Kurikulum Merdeka) has been implemented at SMPN 1 Kecamatan IV Jurai, Pesisir Selatan Regency since the 2022/2023 academic year. The school has conducted workshops at the beginning of each semester to socialize the Independent Curriculum and develop teaching materials in the form of teaching modules. Teachers have also created belajar.id accounts and joined subject-specific communities both within the school and in communities across the regency. This study is motivated by several challenges encountered in implementing the Independent Curriculum, particularly in differentiated learning. These challenges include teachers’ difficulties in recognizing and understanding the individual needs of each student, such as their skill levels, interests, learning styles, and learning preferences. Additionally, teachers face challenges in developing diverse teaching materials that meet students’ needs. Therefore, this study aims to analyze the implementation of differentiated learning within the Independent Curriculum at SMPN 3 Kecamatan IV Jurai, Pesisir Selatan Regency. This research employs a qualitative approach with a descriptive method. The informants consist of the principal, curriculum vice-principal, student affairs vice-principal, and eight teachers at SMPN 1 Kecamatan IV Jurai, selected using purposive sampling. The data consist of primary and secondary data collected through interviews and document studies. Data analysis follows the interactive model by Miles and Huberman, which includes data collection, data reduction, data presentation, and conclusion drawing. The results indicate several stages in implementing differentiated learning: 1) understanding students through diagnostic tests, both academic and non-academic; 2) formulating learning objectives; 3) developing differentiated learning strategies; and 4) using ongoing assessment. Three approaches are applied in differentiated learning at SMPN 3 Kecamatan IV Jurai, Pesisir Selatan Regency: content differentiation, process differentiation, and product differentiation.

Abstract

This study aims to conduct sentiment analysis on user reviews of the Riliv: Mental Health App on Google Play Store using the Support Vector Machine (SVM) algorithm. The analysis process includes review data collection via web scraping, text cleaning using text preprocessing, automatic labeling based on rating scores, data transformation using the TF-IDF method, data splitting with Stratified K-Fold Cross Validation, SVM model training, and performance evaluation. The dataset comprises 2,000 reviews with an imbalanced label distribution: positive (75,3%), netral (5,3%), and negative (19,4%). The classification results show that the SVM model achieved an accuracy of 85.56%. It performed well in identifying positive sentiment with an f1-score of 0.96 and negative sentiment with 0.69. However, the model failed to classify neutral sentiment due to the small number of data, which was insufficient for meaningful pattern recognition. Evaluation and visualization results indicate that label imbalance is a major challenge. Therefore, additional strategies such as data balancing, class weighting, or the use of alternative algorithms are necessary. This research is expected to serve as a foundation for developing a more accurate and fair sentiment analysis system across all sentiment categories in the context of digital mental health services.
