Drying is a critical stage in the post-harvest process of rice to maintain the quality and shelf life of the grain. In Indonesia, traditional sun-drying methods are still widely used, which are highly dependent on weather conditions and require significant time and labor. These limitations often lead to grain moisture levels exceeding the ideal range set by the Indonesian National Standard (SNI 6128:2020), which is 13–14%, thereby reducing the quality and market value of the rice. This study aims to design and implement a semi-automatic rice dryer system based on the Arduino Mega 2560 microcontroller to regulate temperature, humidity, and grain moisture levels automatically. The system utilizes DS18B20 sensors for temperature, DHT22 for humidity, and a grain moisture sensor, while controlling fans, heaters, and agitators through programmed logic. Test results show that the prototype can reduce grain moisture levels more efficiently and consistently than traditional methods, with sensor readings falling within acceptable accuracy tolerances. This tool is expected to provide an effective solution for improving rice drying quality and supporting overall farmer productivity

This study developed a web-based application for the classification and detection of tomato leaf diseases using Convolutional Neural Network (CNN) and You Only Look Once (YOLO) models. The research followed a Research and Development approach that consisted of requirement analysis, system design, implementation, model training, and testing. The CNN model was trained to classify tomato leaf images into specific disease categories, while the YOLO model was designed to detect and localize diseased areas in real time. Both models were integrated into a Flask-based web system to provide accessible and interactive functionality through standard web browsers. Testing results showed that the CNN model achieved an accuracy of 96.1%, effectively identifying disease types such as Early Blight and Bacterial Spot. The YOLO model reached a mean Average Precision (mAP) of 87.3% for real-time detection, successfully locating and labeling infected regions on tomato leaves. The integration of CNN and YOLO models demonstrated strong classification and detection performance, offering an efficient and scalable solution to support early disease diagnosis and digital transformation in precision agriculture.

Background: Project-Based Learning (PjBL) has been widely adopted in engineering education to improve students’ achievement and engagement; however, most studies remain outcome-oriented and provide limited insight into the psychological mechanisms underlying its effectiveness. In technically demanding courses such as Analog Electronics, understanding how instructional strategies influence internal learning processes is essential for promoting meaningful learning. Aim: This study aims to examine the effect of PjBL on students’ learning achievement and to investigate whether self-efficacy and self-monitoring function as mediating variables linking PjBL to academic performance. Method: A quantitative quasi-experimental design with a pretest–posttest non-equivalent control group was employed, involving 50 undergraduate engineering students (25 in the PjBL group and 25 in the control group). Data were collected using a learning achievement test and validated questionnaires measuring self-efficacy and self-monitoring. Data analysis was conducted using ANCOVA to assess treatment effects and mediation analysis with bootstrapping (5,000 resamples) to examine indirect effects. Results: The results indicated that PjBL significantly improved students’ posttest scores after controlling for prior knowledge. PjBL also significantly increased both self-efficacy and self-monitoring. However, mediation analysis revealed that only self-efficacy had a significant indirect effect on learning achievement, while self-monitoring did not show a unique mediating effect, likely due to its strong correlation with self-efficacy. The direct effect of PjBL on achievement remained significant, indicating partial mediation. Conclusion: The findings suggest that PjBL enhances learning achievement both directly and indirectly through strengthening students’ self-efficacy. This highlights the importance of incorporating motivational support within project-based environments to foster effective and sustainable learning in engineering education.

This study investigates the effectiveness of the Project-Based Learning (PjBL) model integrated with Liveworksheet media in enhancing the critical thinking skills of vocational high school students. Employing a true experimental design with a pretest- posttest control group approach, the research compared two groups: the experimental group using PjBL with Liveworksheet and the control group receiving conventional instruction. Data collected from pretest and posttest assessments revealed that the experimental group demonstrated a significant improvement in critical thinking skills, with an average posttest score of 81, compared to 64 in the control group. The pretest scores showed no significant differences between the groups, indicating a similar starting point. Post-intervention results were analyzed using statistical tests, confirming the normal distribution and equal variances of data. The hypothesis testing further validated a substantial difference in critical thinking skills, favoring the PjBL model with Liveworksheet media. These results underscore the effectiveness of this innovative teaching approach in fostering critical thinking skills among vocational students

This study examines the influence of academic competence and soft skills on vocational high school students’ work readiness by integrating multiple linear regression and machine learning classification approaches. A quantitative method was applied using data collected from 90 final-year students. Statistical analyses included descriptive statistics, classical assumption testing, and multiple linear regression. Additionally, machine learning models Decision Tree, Naive Bayes, and Support Vector Machine (SVM) were employed to classify students’ work readiness levels. The dataset was divided into training (70%) and testing (30%) subsets, and model performance was evaluated using accuracy, precision, recall, and F1-score. The results show that academic competence (p = 0.000) and soft skills (p = 0.006) significantly influence work readiness, with R² = 0.348. The SVM model achieved the highest accuracy (85.56%). These findings demonstrate that integrating statistical and machine learning approaches provides both explanatory and predictive insights.

The rapid development of the digital era requires schools, particularly Vocational High Schools, not only to prepare graduates who are ready to enter the workforce but also to foster entrepreneurial interest and competencies to face dynamic business and industry challenges. However, the implementation of entrepreneurship education in schools still encounters several issues, such as limited resources, uneven utilization of digital technology, and the suboptimal role of school management in organizing entrepreneurship programs in a systematic manner. This study aims to analyze the efforts of school management in enhancing students’ entrepreneurial interest in the digital era based on the perceptions of teachers, school management, and students at SMKN 1 Lembah Melintang, Pasaman, Indonesia. This research employed a descriptive quantitative approach. The research subjects consisted of 42 teachers and school management members, as well as 145 students. Data were collected through online questionnaires distributed to all respondents. The collected data were analyzed using descriptive quantitative techniques by calculating frequencies and percentages for each research indicator. The results indicate that the majority of teachers, school management, and students are aware of the entrepreneurship programs implemented at the school. School management is perceived to have provided adequate support and encouraged the use of digital technology in entrepreneurship learning, although further optimization is needed, particularly in terms of practical entrepreneurial activities and supporting facilities. The entrepreneurship program was found to have a positive impact on increasing students’ entrepreneurial interest and contributed to the development of business-related skills relevant to the world of work. Nevertheless, the level of satisfaction, which was generally categorized as moderate, suggests the need to strengthen strategic planning, practice-based implementation, and collaboration with business and industry partners to ensure the sustainability and effectiveness of entrepreneurship programs in vocational schools..
