This study aims to develop Applied Physics teaching materials based on a scientific approach to enhance students' creativity in the Nautical Technology Study Program at the Politeknik Pelayaran Sumatera Barat. Creativity, which includes critical thinking, flexibility, and originality, is an essential competence in science education to address the challenges of the workforce. This study employs the Research and Development (R&D) method with the ADDIE development model, encompassing the stages of Analysis, Design, Development, Implementation, and Evaluation. The results indicate that students previously lacked relevant printed teaching materials, and the learning process relied on digital resources like presentations, which were deemed less scientific. The developed teaching materials cover Statics, Motion Dynamics, Fluids, and Temperature, presented systematically and applicatively. Experts have confirmed that these teaching materials have high feasibility, with an average score of ≥3.26, although some revisions are needed to enhance the context and relevance of the content. Student responses to these teaching materials demonstrate high effectiveness in helping them understand Applied Physics concepts, with average scores for material and language aspects reaching ≥3.09, respectively. Moreover, the scientific activities in the teaching materials successfully encouraged students to think creatively and generate new ideas. In conclusion, the scientific-based Applied Physics teaching materials developed effectively enhance student creativity and are relevant to education and industry needs. This study significantly contributes to innovation in science teaching methods in higher education.

Pumps play an important role in moving fluids from one place to another. In this study, the Ebara 125 x 100 FS4KA centrifugal pump was used. The thing that made the author interested in conducting this research was the reduction in the performance of the centrifugal pump to circulate water from the training pool to the holding tank and back to the pool. The aim of this was to determine the factors causing the decline in the performance of the centrifugal pump. The method used is observation through data collection and data processing, data obtained from the field, namely wear and tear on the impeller diameter, which greatly influences pump performance. Before the pump was repaired with an impeller diameter of 245 mm, the pump capacity was 78 m3/hour, the pump hydraulic power was 5.8 Kw, the pump head was 27.4 m, the pump efficiency was 43.20%, and the fluid speed was 1,014 m/sec. After repairing the Ebara 125 x 100 FS4KA centrifugal pump by replacing the impeller size by 250 mm, the performance of the Ebara 125 x 100 FS4KA centrifugal pump increased by 80 m3/hour, pump hydraulic power 6.04 KW, pump head 28 m, pump efficiency of 45.24%, and fluid velocity of 1,032 m/sec.

The absence of a standardized operational-level practical test instrument for Technology Nautical Study Program cadets has led to inconsistencies in evaluating critical competencies, ultimately affecting the quality of training and readiness in maritime operations. This community service activity was initiated to address this gap by identifying the root causes behind the lack of implementation, such as inadequate alignment between practical assessments and core competencies, and by highlighting the consequential impact on vocational education quality. Using a qualitative approach through lectures, training sessions, and Participatory Action Research (PAR), this study involved lecturers and cadets from AMSS and Poltekpel Barombong. The intervention focused on socializing and implementing a competency-based assessment instrument that, based on preliminary indicators and observational data, demonstrated improvements in measuring participant skills with increased objectivity, validity, and reliability. However, limitations remain in that the instrument currently addresses only operational-level competencies and does not fully encompass all practical scenarios aligned with core competencies. The findings underscore the need for further research to expand and refine assessment tools, particularly at the management level, thereby contributing to enhanced vocational training and competency-based education in the nautical field.

This community service was held in response to the initial finding that Maritime English instruction at SMK Negeri 10 Padang remains hampered by a lack of textbooks aligned with IMO Model Course 3.17, limited teacher training, and students’ insufficient mastery of navigational terminology. The project introduced and disseminated the textbook Maritime English for Navigational Watch Officers developed according to IMO, SMCP, technical terminology, formative exercises, a glossary, and supporting visual resources. A participatory outreach methodology was employed, comprising presentations, group discussions, maritime communication simulations, and a practicality questionnaire. This event took place on 21 July 2025 in the school prayer hall, with participants including Poltekpel Sumbar team, SMK Negeri 10 Padang’s teachers, teaching staff, and students. Quantitative results indicated average “Yes” practicality scores of 70 % from 17 teachers and 83 % from 40 students, particularly regarding ease of use, engaging design, and support for independent learning; concerns remained over textbook ownership and the potential to replace teacher presence. Qualitative feedback underscored the need for online modules, a translated edition, audio–video content, and field visits to Poltekpel Sumbar. The discussion highlights the effectiveness of bilingual instruction, scaffolding, dialogic teaching, and experiential learning in enhancing navigational watch officer competencies. Pedagogical implications include enriching contextual and interactive media; institutional implications stress the importance of formal MoUs, sustainable funding, and local cadre teams; strategic implications advocate for additional ESP maritime titles and digital platforms. The project is envisioned as a replicable model for vocational collaboration to bolster graduate competitiveness in the global shipping industry.
