Abstract

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.

Abstract

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.

Abstract

Welding is one of the essential competencies that students in the Welding and Metal Fabrication Engineering Expertise Program must possess. However, the practical learning process still faces limitations in equipment facilities, both in terms of quantity and usability, requiring students to take turns using the equipment and making practice time less effective. This condition has the potential to affect students’ welding skill outcomes. This study aims to determine the effect of practical equipment facilities on the welding skill outcomes of Grade XI students in the Welding and Metal Fabrication Engineering Department at SMK Negeri 2 Payakumbuh. This study employed a quantitative approach with a correlational method. The research population included all Grade XI students in the Welding and Metal Fabrication Engineering Department of SMK Negeri 2 Payakumbuh, totaling 55 students. The sample was determined using the total sampling technique, so the entire population was used as the research sample. Data were collected through a questionnaire to measure practical equipment facilities and an assessment rubric to measure students’ welding skills. Data analysis included prerequisite analysis tests, namely normality, linearity, and homoscedasticity tests, as well as hypothesis testing using simple linear regression, the t-test, and the coefficient of determination (R²). The results show that practical equipment facilities do not have a significant effect on students’ welding skill outcomes, with a significance value of 0.318 > 0.05. The coefficient of determination (R²) value of 0.019 indicates that practical equipment facilities can explain only 1.9% of the variation in students’ welding skill outcomes, while 98.1% is influenced by other factors outside this study. In addition, the direction of the relationship obtained is negative and not significant, with a regression coefficient value of -0.187. The conclusion of this study emphasizes that practical equipment facilities are not the main factor determining students’ welding skills; rather, other factors play a greater role, such as interest, motivation, theoretical understanding, and the learning process. The implications of this study emphasize the importance of a more comprehensive evaluation of practical learning by considering students’ internal factors and the quality of the vocational learning process.
