This study discusses a student concentration detection system using Convolutional Neural Network (CNN) with the MobileNetV2 architecture. The dataset was adapted from Classroom Student Behaviors and mapped into four concentration categories: highly focused, focused, less focused, and unfocused. The system was tested with a 720p webcam and produced real-time detection data. The evaluation results show an overall accuracy of 75.85%, with the highest precision achieved in the focused class (0.9859) and the highest recall in the highly focused (0.9739) and unfocused (0.9811) classes. The confusion matrix indicates that the focused class was detected most consistently, while highly focused and unfocused classes were often misclassified as focused, resulting in lower precision. In real-time testing, the system operated at an average of 7 FPS and worked optimally when students faced the camera directly with sufficient lighting, but its performance decreased significantly at face angles greater than 45°. User evaluation shows that 75% of students rated the detection results as accurate/very accurate with an average satisfaction score of 3.6 out of 5, and 75% felt assisted in recognizing their concentration level. From the teachers’ perspective, most stated that the results were consistent with classroom observations, and all expressed willingness to reuse the system.

This study was motivated by the lack of standardized and objective assessment instruments for the teaching of the Syofyani Minang Payung Dance at the junior high school level, resulting in an assessment process that remains largely subjective and fails to measure psychomotor, affective, and cultural aspects in a balanced manner. This study aims to design and test the validity and reliability of a performance assessment rubric for the Syofyani Minang Payung Dance in cultural arts education at SMP Negeri 1 Bukittinggi. The research method used is a mixed-methods approach with a sequential explanatory design. The research subjects consisted of three dance instructors serving as expert judges, one cultural arts teacher, and 33 junior high school students. The research instrument was a performance-based assessment rubric covering five competency indicators: basic movement techniques; alignment with musical rhythm and dynamics; expression and character interpretation; mastery of payung props and movement safety; and accuracy of floor patterns and group synchronization. Quantitative data analysis was conducted using IBM SPSS Statistics through the Corrected Item-Total Correlation validity test and Cronbach’s Alpha reliability test, while qualitative data was analyzed using descriptive-interpretive methods. The research results show that all indicators have validity scores above 0.30 and are therefore considered valid, and the Cronbach’s Alpha reliability score is above 0.70, indicating good internal consistency of the instrument. Furthermore, the interview results indicate that the rubric is considered relevant, clear, and aligned with the learning characteristics of Syofyani’s Minang Payung Dance at the junior high school level. Consequently, the developed assessment rubric is deemed suitable for use as an objective, standardized, and contextually appropriate assessment instrument for dance education rooted in local culture.

This study aims to analyze public sentiment toward the hashtag #KaburAjaDulu, which has circulated widely on the social media platform X (formerly Twitter). The hashtag reflects the growing anxiety among the public, especially younger generations, regarding socio-political issues in Indonesia. The data were collected using web scraping techniques, focusing on user-generated tweets that contain the hashtag. A comprehensive text preprocessing phase was conducted to clean the raw data by removing irrelevant elements such as URLs, emojis, numbers, and punctuation. The research applies a hybrid classification approach using a combination of Support Vector Machine (SVM) and Random Forest algorithms to categorize sentiment into three classes: positive, negative, and neutral. The performance of the model was evaluated using metrics such as accuracy, precision, recall, and F1-score to determine the effectiveness of the classification. The study aims to demonstrate that combining algorithms can improve classification performance compared to using a single algorithm. This research contributes to the field of sentiment analysis and provides valuable insights for researchers, policymakers, and social observers in understanding public opinion trends in digital media.

Expressive short story reading instruction requires both verbal and nonverbal skills so that students can convey the story’s content in a communicative and meaningful way. However, the instructional models currently in use tend to focus on only one aspect, resulting in suboptimal development of oral expression. This study aims to describe the innovative design of the Story Physical Expression (SPE) learning model for expressive short story reading instruction. The study employs a library research method with a qualitative descriptive approach. Data were obtained from various books, scientific articles, and relevant research findings, then analyzed using content analysis techniques. The results indicate that the SPE model was developed through the reconstruction of the storytelling and Total Physical Response (TPR) models by integrating verbal and nonverbal skills into a single learning sequence. This model consists of seven components: stimulation and motivation, story reading examples, exploration of physical expression, guided expression practice, story performance, feedback and reflection, and evaluation and reinforcement. The novelty of the SPE model lies in the integration of story immersion, intonation, pronunciation, facial expressions, gestures, and body movements in the expressive learning of short stories. The SPE model serves as an alternative instructional model that can be used to develop students’ oral expression skills in Indonesian language learning.

High-quality forage selection is a central factor in improving Bali cattle performance, particularly in smallholder systems that rely heavily on local feed resources. This study evaluated the effects of odot grass (Pennisetum purpureum cv. Mott) and pakchong grass (Pennisetum purpureum cv. Thailand) on feed intake, average daily gain, and feed conversion ratio of male Bali cattle. The experiment was conducted for 30 days from February to March 2026 at CV. RnB Farm, Gorontalo Regency. Nine male Bali cattle with relatively homogeneous initial body weights of 150–200 kg was assigned to a completely randomized design with three treatments and three replications. The treatments were P0, field grass as the control; P1, 100% odot grass plus concentrate; and P2, 100% pakchong grass plus concentrate. Dry matter intake did not differ significantly among treatments, with values of 6.47 ± 0.19, 6.52 ± 0.19, and 6.55 ± 0.16 kg/head/day for P0, P1, and P2, respectively. In contrast, average daily gain differed significantly, with the highest value observed in P2 at 0.56 ± 0.08 kg/head/day, followed by P1 at 0.52 ± 0.09 kg/head/day and P0 at 0.45 ± 0.06 kg/head/day. Feed conversion ratio also differed significantly, with the most efficient value recorded in P2 at 11.98 ± 2.10. These findings indicate that pakchong grass combined with concentrate provides the best feed efficiency and growth performance, while odot grass remains a promising alternative forage for improving Bali cattle productivity.

This study examines young people’s perceptions of the Free Nutritious Meal Program (Makan Bergizi Gratis/MBG) and its impact on public trust in the government. The MBG program is one of the Indonesian government’s strategic policies aimed at improving nutritional quality, particularly for students, while supporting social welfare and human resource development toward Indonesia Emas 2045. In the digital era, social media plays a significant role in shaping public opinion, especially among Generation Z, who actively consume and disseminate information through online platforms. This research employed a qualitative descriptive approach with in-depth interviews, social media observations, and documentation studies as data collection techniques. The participants consisted of young people aged 18–25 years in Bandar Lampung selected through purposive sampling. The findings indicate that most informants perceive the MBG program positively because it is considered relevant to community needs, particularly in improving children’s nutrition and supporting economically vulnerable groups. However, public trust in the government remains conditional due to concerns regarding transparency, uneven distribution, food quality, and program supervision. The study also reveals that young people distinguish between support for the program itself and trust in the government as an institution. Positive perceptions of the program can increase political trust, but implementation weaknesses may reduce confidence in government performance. Therefore, transparency, consistency, and effective public communication are essential factors in strengthening public trust and ensuring the sustainability of the MBG program.
