Implementation of learning is one of the main tasks of teachers to teach students. The intended learning is the creation of conditions that allow it to occur in students. Learning will improve cognitive, affective, and psychomotor abilities, these abilities are accompanied by experience gained during the learning process that applies anywhere and anytime and can be applied in everyday life. One of the materials for class XI that is difficult for students to understand is the material on the digestive system. One way that can be done is to make it easier for students to understand the material on the digestive system by developing Contextual Teaching and Learning (CTL) oriented student worksheets teaching materials, with this worksheet students can relate learning materials to everyday life. Student worksheet (LKPD) development is carried out using 3 stages of 4-D model development. The stages are defined, design, and develop. The data collection instruments used were validity and response questionnaires. The student worksheets were validated by 3 validators and a response test was conducted on 25 students of class XI and one Biology teacher at SMA Negeri 2 Lembang Jaya. This research produces student worksheets with Contextual Teaching and Learning (CTL) orientation on the digestive system material for class XI. The results of the validity of the student worksheets obtained 91.78% with very valid criteria both in terms of the feasibility of content, language, presentation, and graphics. The results of the teacher's assessment of the practicality of the student worksheets obtained an average of 93.28% with practical criteria and an average student assessment of 86.65% with very practical criteria in terms of ease of use, efficient learning time, and benefits. It can be concluded that the student worksheets (LKPD) oriented to Contextual Teaching and Learning (CTL) with a valid category and the responses of teachers and students about its practicality are included in the very practical category.

Low student engagement and modest Computer-Aided Design (CAD) learning outcomes remain challenges in automotive engineering education. This study examined the implementation of Problem-Based Learning (PBL) to support student engagement and CAD learning achievement in an Automotive Engineering course. A Classroom Action Research design was conducted in two cycles comprising planning, action, observation, and reflection. The participants were 25 Automotive Engineering students in the 2025/2026 even semester. Data were collected through observation, pre-test, post-test, and documentation, and analyzed descriptively. The results showed that learning mastery increased from 72% in Cycle I to 88% in Cycle II, while the average score increased from 70.04 to 78.48. Classroom observations also indicated more active participation in discussion, problem-solving, group work, and presentations. These findings suggest that PBL can support CAD learning achievement and student engagement in this classroom action context.

Capaian pembelajaran merupakan output dari kegiatan pembelajaran yang ditentukan melalui kegiatan pengukuran atau evaluasi, yang bertujuan mengukur tingkat pencapaian yang telah diraih. Sementara itu, keaktifan peserta didik merujuk pada keterlibatan atau kesibukan mereka dalam proses pembelajaran. Keaktifan ini muncul dalam berbagai bentuk kebutuhan belajar, namun tingkatnya dapat berbeda-beda bergantung pada bentuk kegiatan yang dilakukan, isi pelajaran yang sedang dikaji, dan sasaran yang hendak diraih. Rendahnya keaktifan peserta didik juga akan berdampak kepada hasil belajarnya itulah yang melatarbelakangi penelitian ini yang telihat pada mata kuliah Kesehatan dan Keselamatan Kerja (K3). Tujuan penelitian adalah meningkatkan keaktifan dan hasil belajar melalui penerapan model Problem Based Learning (PBL) pada mata kuliah Kesehatan dan Keselamatan Kerja (K3). Penelitian ini menggunakan metode kuantitatif dengan jenis penelitian tindakan kelas. Hasil penelitian ini menunjukkan bahwa untuk Persentase keaktifan belajar terjadi peningkatan yaitu siklus 1 pertemuan I (45 %), siklus 1 Pertemuan II (51,33%), Siklus 2 Pertemuan I (61,66%), Siklus 2 pertemuan II (73,33%). Begitu juga dengan persentase hasil belajar yaitu pratindakan (64,08%), siklus 1 (70,04%), dan siklus 2 (77,36%). Dapat disimpulkan adanya peningkatan keaktifan dan hasil belajar mahasiswa dalam perkuliahan yang dapat dilihat pada siklus 2

This study is motivated by the low utilization rate of the National Digital Samsat (SIGNAL) application in Padang City, which only reached 2.1%. According to Grajek and Kretschmer (2008), a digital technology can be considered to have reached the critical mass phase when adoption rates range between 10% and 25% of the target market (Mahler & Rogers, 1999; Cool et al., 1995). Therefore, the adoption level of SIGNAL in Padang is still considered very low and has not yet entered a self-sustaining phase. This study aims to analyze the factors that influence the acceptance of the SIGNAL application using the Technology Acceptance Model (TAM). A quantitative method was applied, using data from 99 respondents analyzed through PLS-SEM with SmartPLS 4.0. The results show that Perceived Ease of Use (PEU) significantly affects both Perceived Usefulness (PU) and Attitude Toward Using (ATU), while PU does not significantly influence ATU. PU and ATU have a significant influence on Intention to Use (ITU), which subsequently affects Actual System Usage (USE). The strongest outer loading indicators were: “easy to understand” (0.854) for PEU, “improves productivity” (0.803) for PU, “rejecting alternative options” (0.861) for ATU, “motivation to continue using” (0.852) for ITU, and “user satisfaction” (0.856) for USE.
