Abstract

This research is based on the limited references to existing independent curriculum teaching tools. This research aims to develop an independent curriculum teaching tool on global warming material to see the feasibility, response of educators and the effectiveness of the teaching tool. The type of research used is Research and Development (R&D) according to Sugiyono which consists of 10 stages, namely potential and problems, data collection, product design, design validation, design revision, small scale trials, product revisions, large scale trials, product revisions. , and mass production, but this research is limited to large-scale tests. The product in this research is a teaching tool, namely a teaching module. The research was conducted in April-September 2023 at MAN 1 Bengkulu City with the research subjects being class X 3 students at MAN 1 Bengkulu City, totaling 34 students. The research instruments used were interviews, validation sheets, response questionnaires and test instruments. The results of the teaching device feasibility test were said to be very valid with a score of 87.69%. The results of the educator response test were very good with a score of 91%, which educators felt was helpful in expressing the concept of global warming with simple experiments and was useful for students in building independent learning so as to increase understanding and learning outcomes in global warming material. The effectiveness of the teaching tools can be seen from the N-Gain, which is 0.618 in the medium category, which shows that the use of the Guided Discovery Learning-based independent curriculum teaching tools that were developed has proven to be effective in improving student learning outcomes on global warming material.

Abstract

Providing learning resources related to the use of natural resources and the environment around us is very necessary, so that the learning process in class is more active and interesting. This research aims to develop a natural product organic chemistry (KOBA) learning module based on research results on the use of natural product compounds, so that students are more motivated in learning. Research and Development (R&D) or development research uses the ADDIE development model which consists of Analysis, Design, Development, Implementation, and Evaluation. The research subjects were 24 seventh semester students of the 2023/2024 Bengkulu University FKIP Chemistry Education Undergraduate Study Program. Data collection techniques use expert validation questionnaire sheets and student response questionnaires and data analysis techniques use quantitative data analysis. The results of the research show that the validator's assessment of the developed module obtained an average score of 93.60%, which is included in the very valid category, while the results of student assessments of the developed module obtained an average of 93%, which is included in the very interesting category. Based on the results of the expert validation assessment questionnaire and student response questionnaire, it can be concluded that the module developed is very suitable for use as a learning resource in the learning process.

Abstract

The rapid advancement of Industry 4.0 has catalyzed the integration of artificial intelligence (AI) into smart manufacturing, with predictive maintenance emerging as a crucial application to reduce downtime and optimize operational efficiency. This study aims to develop and evaluate a deep learning-based predictive maintenance model by leveraging real-time sensor data from a smart factory environment. A convolutional neural network (CNN) architecture was implemented to detect anomalies and predict machinery failures in advance. The dataset, consisting of multivariate time-series signals from industrial sensors, was preprocessed and used to train, validate, and test the model’s predictive performance. Results indicate that the proposed deep learning model achieved a prediction accuracy of 94.6%, outperforming traditional statistical and machine learning methods in both precision and recall. The implementation of this AI-driven system enables proactive maintenance strategies, minimizing production losses and extending equipment lifespan. In conclusion, the research demonstrates the feasibility and effectiveness of deep learning in predictive maintenance applications for smart manufacturing systems and offers a scalable solution adaptable to diverse industrial settings.

Abstract

This study aims to improve students’ conceptual understanding in a contextual and meaningful way through the development of an acid-base e-module based on ethnoscience using the Culturally Responsive Transformative Teaching (CRTT) model. The research employed a Research and Development (R&D) method with the 4D model, limited to the Develop stage. The instruments used included validation sheets, student response questionnaires, and concept understanding tests. Validation results showed that the e-module was highly valid, with a score of 82.72% for content and 87% for media. Student responses were also very positive, with a score of 90.66%. The average N-Gain was 0.83, indicating a high increase in conceptual understanding, particularly in the indicator of relating concepts (0.86). The e-module integrates local ethnoscientific elements from Rejang Lebong culture, such as lemea and candied kedondong, into the acid-base topic. The findings suggest that this e-module is effective for chemistry learning and serves as an innovative, contextual teaching material that supports local cultural preservation. Keywords: E-module, Acid-Base, Ethnoscience, CRTT, Concept Understanding.

Abstract

Chemistry is one of the subjects that is still considered difficult and less interesting by most students, including those at SMAN 2 Bengkulu Tengah. The use of Chemistry Software has become one of the learning media solutions that can help students in learning chemistry. Therefore, an introduction to Chemistry Software was conducted for the students of SMAN 2 Bengkulu Tengah. This activity was carried out through an introduction and demonstration method and took place on September 26, 2025. Based on the results of the satisfaction questionnaire distributed, the majority of participants stated that the implementation of the introduction and use of Chemistry Software was interesting (74%) and very interesting (21%). In addition, the participants felt more motivated to learn chemistry and hoped that similar activities could be held again. Overall, this activity ran smoothly and was enthusiastically participated in by the students. Keywords: Avogadro; IqMol; Computational Chemistry; HyperChem
