Abstract

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.

Abstract

Cargo handling is a core operational activity in ports that directly affects berth time efficiency and vessel departure punctuality, as any delay in this process will impact the overall sailing schedule. This study aims to analyze the influence of cargo handling operations and passenger boarding on the departure punctuality of the passenger vessel KM Bukit Siguntang and to formulate strategic operational recommendations to improve departure time performance. The study employs a descriptive qualitative approach, with data collected through semi-structured interviews, field observations during Voyage 16.2025, and operational documentation including ETA, ETD, and actual ATD records. Informants consist of ship crews and port operational personnel. Data were analyzed using an interactive analysis model involving data reduction, data display, and conclusion drawing. The findings indicate that the impact of delays is proportional to berth duration; therefore, shorter port stays carry a higher risk of operational time loss. The study recommends the implementation of proportional buffer time, stricter boarding cut-off policies, optimized cargo planning, improved equipment readiness, and the establishment of a monitoring and evaluation system based on key performance indicators to enhance vessel departure punctuality.

Abstract

In an increasingly competitive service industry, understanding the determinants of user satisfaction is essential for organizational growth and customer retention. This study aims to examine the effects of service quality and service loyalty on user satisfaction at PT. Adhigana Pratama Mulya Batam. Employing a quantitative ex-post facto design, data were collected through questionnaires distributed to 200 respondents, consisting of ship crew members as direct users of the company’s services. The data were analyzed using multiple linear regression with the SPSS application. The results reveal that both service quality (t(197) = 4.419 > 1.984, p < 0.001) and service loyalty (t(197) = 9.957 > 1.984, p < 0.001) have significant positive effects on user satisfaction, while their combined influence is also statistically significant (F(2, 197) = 96.379 > 3.00, p < 0.001). These findings indicate that higher levels of service quality and employee loyalty lead to greater user satisfaction. The study suggests that the company should strengthen employee training, enhance user engagement, and continuously improve global service standards. Future research should incorporate additional factors such as infrastructure, technological facilities, pricing competitiveness, and brand image to obtain a more comprehensive understanding of user satisfaction

Abstract

The rapid growth of maritime tourism in Banyuwangi, Indonesia, presents both significant economic opportunities and increasing pressure on fragile marine ecosystems. This article is framed as a conceptual and experiential case study that examines the role of passenger education in promoting marine environmental sustainability within yacht tourism operations. Drawing on participatory observation grounded in the author’s professional experience as a yacht captain, the study identifies recurring patterns of environmentally detrimental passenger behaviour and develops a simple educational intervention embedded within routine operational practices. The proposed 5-Minute Pre-Sail Briefing model integrates concise sustainability messages into standard operating procedures, with emphasis on waste prevention, coral reef protection, and respectful interaction with marine life. The findings represent observational insights rather than empirical validation, suggesting that brief, context-specific educational communication has the potential to encourage pro-environmental behaviour among yacht passengers. Although the model is not intended to be generalisable, it demonstrates potential transferability to comparable small-scale maritime tourism contexts. Overall, this study underscores the importance of behavioural and educational strategies as complementary elements of sustainable maritime transport.

Abstract

This study aims to examine the effects of rewards, work–life balance, and coworker support on employee job satisfaction. Employing a quantitative design with independent samples t tests, the research population comprised all employees of Politeknik Pelayaran Sumatera Barat in 2025 (150 persons), with a purposive sampling technique based on percentage to select respondents. So, the pilot sample is 37 persons, and the research sample is 113 persons. A structured questionnaire was used to measure the variables of recognition, work–life balance, coworker support, and job satisfaction, and data were analyzed using SPSS. The findings reveal that rewards, work–life balance, and coworker support significantly influence job satisfaction (t-calculated > t-critical; 21.849, 14.508, 21.991 > 1.66). Rewards also impact work–life balance, which in turn affects coworker support, although they do not directly influence it. Implications of this research suggest that implementing a structured reward system can be an effective strategy to enhance job satisfaction in vocational education settings. Future studies are advised to employ mixed methods designs and broaden the sample to multiple institutions to verify and generalize these results. It is recommended that the management of Politeknik Pelayaran Sumatera Barat develop and implement integrated reward programs and flexible work policies to optimize employee well-being and productivity.

Abstract

This study examines how information literacy influences students’ disaster preparedness by incorporating risk perception as a mediating variable. Disaster-prone higher education environments require strong information comprehension skills to support readiness against potential hazards. The research involved 184 students from Merchant Marine Polytechnic of West Sumatra and STKIP Ahlussunnah, selected using purposive sampling. quantitative survey design approach was applied using SEM-PLS path analysis to evaluate direct and indirect effects. The results show that information literacy significantly influences disaster preparedness through an indirect effect mediated by risk perception (β = 0.205; p = 0.000). This finding highlights that risk perception strengthens the translation of information literacy into concrete preparedness actions. Practically, institutions should design information literacy programs that enhance not only access to technical data but als4o students’ awareness and appraisal of disaster risks. This study is limited by its focus on two campuses in a specific geographic area, suggesting the need for broader comparative studies. Overall, the research confirms that incorporating psychological components such as risk perception is essential for optimizing disaster preparedness strategies among university students.

Abstract

Penelitian ini didasari oleh kebutuhan untuk memahami faktor penentu prestasi matematika mahasiswa, khususnya pemecahan masalah dan efikasi diri, yang belum banyak dikaji secara simultan. Tujuan penelitian adalah menguji H1 mengenai pengaruh signifikan pemecahan masalah terhadap performa matematika, H2 mengenai pengaruh signifikan efikasi diri, dan H3 mengenai pengaruh simultan kedua variabel tersebut. Metode penelitian menggunakan pendekatan kuantitatif ex-post facto. Penelitian ini dilaksanakan di Politeknik Pelayaran Sumatera Barat, dari April sampai September 2025. Populasi penelitian yaitu mahasiswa angkatan VIII dan IX, sebanyak 158 orang. Sampel penelitian dipilih menggunakan total sampling yang terdiri dari 40 mahasiswa angkatan VIII sebagai sampel uji coba instrumen dan 118 mahasiswa angkatan IX sebagai sampel utama. Instrumen penelitian berupa kuesioner terstruktur yang telah diuji validitas dan reliabilitasnya. Teknik analisis data menggunakan regresi linear berganda. Hasil penelitian menunjukkan bahwa secara simultan pemecahan masalah dan efikasi diri berpengaruh signifikan terhadap prestasi matematika, dengan nilai koefisien regresi yang signifikan pada ??=?0,05. Kesimpulan penelitian menyatakan bahwa integrasi strategi pemecahan masalah dan penguatan efikasi diri merupakan kunci peningkatan performa matematika mahasiswa. Saran bagi praktisi pendidikan antara lain merancang modul pembelajaran yang menggabungkan latihan pemecahan masalah dan kegiatan peningkatan efikasi diri melalui refleksi, serta melakukan penelitian lanjutan di berbagai institusi untuk memperkuat generalisasi temuan.     This study was motivated by the need to understand the determinants of students’ mathematics performance, specifically problem-solving skills and self-efficacy, which have rarely been examined simultaneously. The objectives are to test three hypotheses: H1: problem-solving ability has a significant effect on mathematics performance; H2: self-efficacy has a significant effect on mathematics performance; and H3: the two variables jointly affect mathematics performance. Employing a quantitative ex post facto design, the research was conducted at Politeknik Pelayaran Sumatera Barat from April to September 2025. The population is students batch VIII and IX (N = 158). By using total sampling, 40 batch VIII students served as the trial sample, while 118 batch IX students constituted the main sample. A structured questionnaire validated for content and reliability was used to collect data. Multiple linear regression analysis was used as a data analysis technique. The results revealed that problem-solving and self-efficacy together significantly predicted mathematics performance (? = 0.05). It is concluded that integrating problem-solving strategies with enhanced self-efficacy is key to improving students’ mathematics performance. Practitioners are advised to develop instructional modules that combine structured problem-solving exercises with reflective self-efficacy enhancement activities, and to undertake further research across diverse institutions to strengthen the generalizability of these findings.

Abstract

In response to the increasing demands for 21st-century competencies, this study adopts an explanatory quantitative research design to investigate the mediating role of Immersive Learning Experiences (ILE) in the relationship between Augmented Reality (AR) and Learning Motivation (LM) toward the acquisition of 21st-Century Skills (CS). Using a quantitative explanatory design with Partial Least Squares Structural Equation Modeling (PLS-SEM), this study analyzes data from Generation Z students (aged 17–25) enrolled at the Ministry of Transportation's maritime campus in Sumatra to evaluate this relationship. The results show that AR has a significant positive effect on ILE (β = 0.603; t = 3.878; p < 0.001), while its direct effect on 21st-Century Skills (CS) is negative and insignificant (β = -0.225; t = 1.461; p = 0.144). ILE, in turn, significantly influenced CS (β = 0.599; t = 4.928; p < 0.001) and significantly mediated the effect of AR on CS (β = 0.361; t = 2.924; p = 0.003). Meanwhile, Learning Motivation (LM) did not show a significant direct or indirect effect on CS through ILE. This finding highlights that ILE plays a significant mediating role in linking AR to 21st-century skills, while LM did not show a comparable influence. This suggests that intrinsic factors such as motivation are crucial, with technology-enhanced learning environments playing a more dominant role in developing 21st-century skills. The limited mediation effect of ILE in the LM–CS pathway may stem from the inherently cognitive–affective nature of motivation, which may require different pedagogical support. Future research is recommended to incorporate moderator variables such as digital literacy and adopt a longitudinal design to assess the sustained impact of immersive learning on skill development.
