Abstract

This research is motivated by the lack of attractive learning materials used by teachers, so that students have difficulties in understanding the lessons. One solution is to design learning materials in the form of Student Worksheets (LKPD) using a learning model that can improve the abilities and interests of students. The model used in the design of this LKPD is a model (Predict Observe Explain POE. The research carried out includes the type of Research and Development (R&D). The data collection instrument is an LKPD questionnaire based on the Predict Observe Explain model, a questionnaire to determine the practicality of the LKPD. LKPD based on the Predict Observe model Explain was tested at SMAN 2 Lubuk Alung Class X Semester 1. Based on the results of the LKPD validation analysis by the validator, a valid LKPD was obtained with an average score of 79.13% of the validity of the lecturer's questionnaire, and 80% of the validity of the teacher's questionnaire. POE-based LKPD which is very practical with an average score of 78.30% of the practicality of teachers, and 85.83% of practicality of students.

Abstract

COVID-19 pandemic has changed many things in human life, including education where the learning process is now required to be online. Online learning has various drawbacks, one of which is the difficulty of students and lecturers connecting within the specified lecture time. Therefore, flexible and easily accessible learning media is needed to increase student understanding. Contextual learning videos are the solution that can answer these problems because of their flexibility and ease of access. The practicality of learning videos was evaluated through student responses to aspects of Ease of Use, Time Effectiveness, Attractiveness, and Benefits. The average score for the Ease of Use aspect is 86.24%, for the Time Effectiveness aspect it is 85.94%; the Attractiveness aspect scored 82.81%, and the Benefit aspect scored 85.42%. This study indicates that the learning video used was practical and very helpful in the online learning process during the Covid-19 period

Abstract

This research was conducted due to the problem of cadets' leadership, which is still not perfect. The cadets' leadership is assumed to be influenced by parenting patterns from the institution and their self-efficacy. This research aims to describe the influence of parenting patterns and self-efficacy on the leadership of the cadet regiment. This quantitative research applied ex post facto methods. The population was the cadets of Batch VII and VIII at Merchant Marine Polytechnic of West Sumatera. Accordingly, the research sample used a probability sampling technique with proportionate stratified random sampling by using the Slovin formula. The total sample of this research was 191 cadets, while the instrumentation was a questionnaire about parenting patterns, self-efficacy, and leadership. The data collection technique involved giving a questionnaire directly to the sample. The data analysis technique used multiple linear regression analysis by using the SPSS application. The results showed that Hypotheses 1, 2, and 3 were accepted, which means parenting patterns and self-efficacy influenced the leadership of the cadet regiment, and there is an influence of self-efficacy and parenting patterns simultaneously on the leadership of the cadet regiment. The relevant practical implication of this research focused on both internal stakeholders, namely the lecturers or officers and the cadets of Merchant Marine Polytechnic of West Sumatera. Therefore, it is recommended that the director and management pay attention to the parenting patterns and the cadets pay attention to their self-efficacy in order to develop better leadership of the cadet regiment.

Abstract

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.
