This research based on the problem of the learning process of the Engineering Mechanics course. The teacher center learning process causes students to be passive so that students feel bored because of one way communication. Based on data student learning outcomes, it is still not well achieved, therefore it is necessary to apply the numbered heads together learning model to improve learning motivation and learning outcomes. This type of reseach is a factorial 2x2. The subjects of this study were 48 students. The sampling technique is carried out random cluster sampling. Data collection by dissemination of learning motivation questionnaires and learning outcome test instruments and analyzed using two ways anova. Based on the results of data testing, it can be concluded that the Numbered heads together learning model can improve student motivation and learning outcomes. Penelitian ini dilatar belakangi permasalahan proses pembelajaran mata kuliah Mekanika Teknik. Proses pembelajaran yang terpusat pada dosen menyebabkan mahasiswa menjadi pasif sehingga mahasiswa merasa bosan karena komunikasi satu arah. Berdasarkan data hasil belajar mahasiswa masih belum tercapai dengan baik, maka dari itu perlu dilakukan penerapan model pembelajaran numbered heads together dalam peningkatan motivasi belajar dan hasil belajar. Jenis penelitian ini eksperimen dengan desain faktorial 2x2. Subjek penelitian ini mahasiswa yang berjumlah 48 orang. Teknik pengambilan sampel dilakukan random cluster sampling. Pengumpulan data dengan penyebaran angket motivasi belajar dan Instrumen tes hasil belajar dan dianalisa dengan two ways anova. Berdasarkan hasil pengujian data dapat disimpulkan bahwa model pembelajaran numbered heads together dapat meningkatkan motivasi belajar dan hasil belajar mahasiswa.

Kenagarian Koto Tinggi, Kecamatan Baso, Kabupaten Agam, dikenal sebagai daerah penghasil ubi jalar berkualitas tinggi. Namun, petani di wilayah ini menghadapi tantangan besar akibat proses pencucian ubi jalar yang masih dilakukan secara manual. Metode ini menghabiskan banyak waktu dan tenaga serta kurang efisien, yang berpotensi menurunkan nilai jual produk. Dalam upaya mengatasi masalah ini, pengabdian masyarakat bertujuan untuk meningkatkan efisiensi dan kualitas pencucian ubi jalar melalui penerapan teknologi mesin pencuci. Hasil dari pengabdian ini adalah tercipta sebuah mesin pencuci ubi jalar dengan kapasitas 300 kg/jam. Dengan menggunakan mesin pencuci ubi model rotary ini, mitra dapat meningkatkan produktivitasnya dan mengurangi beban kerja fisik. Mesin ini bekerja dengan prinsip putaran drum yang dilengkapi sikat pembersih, memungkinkan ubi bersentuhan dengan alat pembersih saat berputar, sehingga kotoran dan tanah dapat dihilangkan secara efektif. Setelah serah terima mesin dan pelatihan penggunaan kepada mitra pada 8 September 2024, hasilnya mulai terlihat. Dengan penerapan teknologi ini, nilai jual ubi jalar mengalami peningkatan dari Rp 4.500/kg menjadi Rp 5.500/kg. Keberhasilan ini tidak hanya meningkatkan pendapatan petani tetapi juga membuka peluang untuk diversifikasi produk, menjadikan kegiatan ini bermanfaat bagi masyarakat di Nagari Koto Tinggi.

Flat-hull ships are known to have higher resistance than streamlined hulls. Although the Hull Vane® concept has been proven effective as a stern-mounted energy-saving device through pressure-field modification and stern-wave interaction, most previous studies have focused on straight-foil configurations (straight planform). The effect of planform shape optimization, particularly the sweptback configuration, on the hydrodynamic performance of flat-hull ships is limited in the literature. This study modifies the geometry of a Hull Vane® into a sweptback stern foil and evaluates its performance using Computational Fluid Dynamics simulations. The results show that a 15° sweptback angle yields the greatest reduction in total drag. Velocity contour analysis shows a narrower wake and a more uniform velocity-gradient distribution in the stern area for the 15° swept-back stern-foil configuration compared to other configurations. Meanwhile, the turbulence length distribution shows a tendency toward reduced intensity of large-scale turbulent structures behind the ship, indicating improved wake-flow characteristics. The identified drag reduction mechanism primarily stems from improved pressure recovery and modified pressure distribution in the stern area, which is consistent with the working principle of Hull Vane®. Optimizing the sweptback planform geometry yields more efficient flow interaction than the straight-foil configuration. These findings indicate that planform optimization is an important design parameter in the development of stern foils to improve the hydrodynamic efficiency of medium-to high-speed commercial vessels.

Advances in artificial intelligence (AI) have been widely used in learning innovation. This study aims to determine the effectiveness of using AI chatboxes integrated with case method on the science learning outcomes of basic education students. This research is a quasi-experimental research with a pretest-posttest control group design, which allows to compare learning outcomes in both sample classes. Data collection was carried out through pretest and posttest tests to measure the improvement of learning outcomes, and analysis of research data using SPSS 22. The population used was basic education students at Padang State University. The results showed that the use of AI chatbox integrated case method was quite effective in improving science learning outcomes with the acquisition of n-gain in the experimental class of 0.62 with a moderate category. The results of hypothesis test analysis show the Sig value. 0.004 <0.05 so that Ha is accepted. These results prove that the use of AI chatboxes integrated with the case method is effective in improving the science learning outcomes of basic education students. This research shows that the innovative use of AI technology in learning can have a positive impact on student academic achievement, especially in the field of basic education.

Low creative thinking skills in automotive engineering learning can limit students’ ability to generate, adapt, and elaborate technical solutions. This study described the implementation of Problem-Based Learning (PBL) and examined changes in students’ creative thinking skills in the Fundamentals of Automotive Engineering course. A Classroom Action Research design was used with 21 Automotive Engineering students and conducted in two cycles consisting of planning, action, observation, and reflection. Data were collected using observation sheets on creative thinking indicators and analyzed descriptively based on creativity categories. In the pre-cycle condition, most students were classified as fairly creative (52.38%), while only 4.76% were very creative. After PBL implementation in Cycle II, the creative category increased to 47.62% and the very creative category increased to 28.57%, while the least creative category decreased to 0%. These findings suggest that PBL can support the development of students’ creative thinking in automotive engineering learning.

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
