Abstract-this study aims to reveal the effectiveness of the seven steps of Project based learning model (PjBL) in order to enhance the student's productive competences. The implementation of the PjBL model was implemented in two places at different times, there were at Akademi Komunitas Negeri Tanah Datar and Akademi Komunitas Negeri Pesisir Selatan. Previously, the seven steps of PjBL model was validated by experts judgment and measured by Aiken coefficient significantly (0.796), also this syntax e reliable to be implemented in vocational learning process. The seven steps, consisting of: (1) the formulating the expected learning outcome, (2) understanding the concept of the teaching materials, (3) skills training, (4) designing the project theme, (5) making the project proposal, (6) executing the tasks of projects and (7) presentation of the project report. The study showed that the implementation of seven steps of PjBL, were practice and effective to enhance student's productive competences.
Developing engineering students whose ability to work and make a real contribution to the development of technology can be done not only after they have graduated from college but also when they are still in college. One of the strategies is by implementing project-based learning with the project based on the potential of the student's region. This study aims to reveal students’ perceptions of learning and soft skills acquisition toward the implementation of the strategy to answer whether the project is effective to implement. This study was conducted on fifty-one Indonesian college students who took Mechanical Drawing course. It belongs to a one-shot case study with mixed-method approach. The result shows that the project based on the potential of the student’s region is effective to raise their perception of motivation, interest, real-world, very beneficial, learning more lecture and enjoyable so that they learn more actively and provide more time to study. It also develops students’ soft skills, including teamwork, project management, communication, and interpersonal skills. The results may have pedagogical implications in improving learning quality in Mechanical Drawing course by enriching project references used in implementing project-based learning. Furthermore, the project given can be a solution in developing the potential of the students’ regions.
Flat hull ship has some advantages in the manufacturing aspect which are relatively easy to fabricate and does not require high technology equipment. This ship has a weakness where the resistance of flat hull ship is bigger than the other ships among streamlined bow. A factor that influences the ship resistance is the type of bow. So, this study is needed to investigate the effects of bow design and ship resistance. This study aims to reveal the influence of various bows design on resistance and speed of flat hull ship. This study method is numerical analysis using Maxsurf software. The analysis was carried out on four types of bow direction for flat plate hull types, namely Raked Bow, Maier Form, Raked Bow II, and Plumb Bow. The result shows that the flat hull ship with the Raked Bow had the lowest resistance and power. Meanwhile, the flat hull ship with raked bow II had the highest resistance. These results can be a guide for the shipping industry on development and production, and for other researchers in developing the flat hull ship.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
