Abstract

Background: The maritime industry's increasing emphasis on holistic well-being and environmental responsibility necessitates a reevaluation of traditional training methods. This research evaluates maritime education program effectiveness in preparing cadets for industry demands, uniquely integrating health and sustainability with vocational competencies. This study aimed to evaluate the adequacy of current maritime education in preparing cadets for the physical, mental, and vocational demands of seafaring, and to identify methods for better integrating health and sustainability into the curriculum. Methods: This qualitative study explored cadet preparedness in maritime education, focusing on health, sustainability, and vocational competencies. Data were collected through semi-structured interviews with 30 participants, including maritime experts, lecturers, and graduates, selected for their diverse perspectives. Classroom and training observations supplemented interview data, providing a holistic view of current practices. Thematic analysis was employed to identify key themes related to competency development and sustainability, allowing for cross-group comparisons. Finally, narrative synthesis integrated findings into a cohesive understanding of how maritime education can better prepare future seafarers. This multi-method approach ensured a comprehensive and triangulated dataset, enhancing the robustness of the research findings. Results: The results indicate that current programs effectively prepare cadets for physical and vocational challenges, and sustainability practices are incorporated. However, there is a need for enhanced mental health support and deeper integration of contemporary sustainability practices. Conclusions: To ensure a resilient and sustainable workforce in the evolving maritime industry, it is crucial to refine maritime education by balancing physical, mental, and vocational competencies with comprehensive sustainability training.

Abstract

This research was motivated by the many difficulties experienced by students in the mathematics learning process which had an impact on the occurrence of errors in working on mathematics story problems. These errors need to be known so that it is easier to find solutions so that these errors can be minimized. This research aims to determine the types and causes of errors made by students in solving mathematics story problems on single interest and compound interest materials using Polya's steps. This research method is qualitative with descriptive research type. The research subjects consisted of 2 students from 13 class XI TKP SMKN 1 Pariaman students, with the criteria being 1 student each from the medium group and 1 student from the low group. Data collection techniques include tests and interviews. The results of the research show that the percentage of errors made by students in solving mathematics story problems on single interest and compound interest material using Polya steps is: in question number 1, the biggest error made in the step of understanding the problem was 23.08%. Question number 2, the biggest error made during the rechecking step was 15.38%. In question number 3, the biggest mistake made in the step of understanding the problem was 19.23%. The factors that cause students to make mistakes include, not being used to writing information on questions using their own words, not writing down what they know and what is asked in the question correctly, not focusing when working on questions, not being careful in carrying out the calculation process, not being used to checking again, and rushing through the settlement process.

Abstract

This research aims to analyze the evaluation results of micro teaching lectures for Islamic Education students using assessment indicators of teaching skills based on Islamic values. Islamic Education students are prepared to become prospective Islamic Education teachers through basic teaching skills that consist of skills in opening, explaining, questioning, providing reinforcement, variation, using media, managing the classroom, and closing the learning process. The observation results show that the Islamic Education students have not optimally implemented Islamic values in micro teaching practices. The preliminary questionnaire results with two indicators, opening and questioning skills, indicate that 70% of respondents are not skilled in using Islamic values. This research uses a mixed method approach by combining analysis of the results of a questionnaire on Islamic teaching skills, with coursework grades and interviews. The results show that the highest micro teaching skills based on Islamic values are found in the indicators "delivering learning objectives in an Islamic way" and "providing a review of the material and relevant connections with Islamic concepts through verses and hadiths," both of which achieved 100% (Very Skilled). In contrast, the skills with the lowest achievement of Islamic values are found in the indicator "preparing students' mental state in an Islamic way," with a percentage of 50% (Less Skilled).

Abstract

This study aims to analyze the impact of Single Truck Identification Data (STID) and Occupational Health and Safety (OHS) on the smooth flow of goods and its implications on logistics efficiency at Tanjung Priok Port. The main issue faced at the port is the irregularity in the distribution of goods due to delays in vehicle verification and suboptimal safety conditions, which reduces logistics efficiency and affects the operational performance of the port. This study adopts a quantitative approach with a cross-sectional design, involving 380 respondents, including truck drivers, terminal operators, and port management, selected through purposive sampling. Data collection was carried out via questionnaires and analyzed using SmartPLS to test the direct and indirect effects among the variables. The results indicate that STID significantly affects the smooth flow of goods (t-statistic = 3.483) and logistics efficiency (t-statistic = 2.730), while OHS significantly affects the smooth flow of goods (t-statistic = 4.192) and logistics efficiency (t-statistic = 5.125). Additionally, both variables also have an indirect impact on logistics efficiency through the smooth flow of goods. In conclusion, the implementation of STID and OHS can improve logistics efficiency. It is recommended to strengthen the implementation of STID and the OHS program at the port. Future research could explore this further using a qualitative approach and longitudinal analysis.

Abstract

Low reflective thinking skills and a lack of understanding of local values among students in Islamic Religious Education are problems at State Senior High School 1 Lintau. Theoretical learning makes it difficult for students to relate religious teachings to the ethnographic culture of Minangkabau. This study aims to compare the effectiveness of project-based learning and differentiated learning models in improving students' reflective thinking skills in integrated Islamic Education lessons incorporating Keminangkabau ethnography. The study used a quantitative comparative approach through an experiment involving 158 students and 4 educators. Data were collected through questionnaires and interviews. The results indicate that the differentiated learning model is more effective in enhancing self-awareness, reflection in action, and future planning. Meanwhile, the project-based model is superior in fostering social reflection. These findings highlight the importance of selecting appropriate learning models to develop reflective skills and strengthen understanding of local values, thereby making Islamic Education more meaningful and contextual.
