Abstract

High logistics costs remain a major challenge in supporting export-import competitiveness, particularly in archipelagic countries that rely heavily on maritime transportation. One strategic approach considered capable of reducing logistics costs is the implementation of a multimodal maritime transportation system that is effectively integrated with other modes of transportation. This study aims to analyze the impact of increasing the efficiency of multimodal maritime transportation on export-import logistics costs, focusing on key implementation factors, the current state of multimodal system efficiency, and integration barriers that cause cost inefficiencies. The research method used was a literature review of various scientific journals, research articles, international agency reports, and relevant academic publications published between 2020 and 2025. The analysis was conducted using a content analysis approach to identify patterns, key findings, and gaps in previous research. The results of the study indicate that the efficiency of multimodal maritime transportation is significantly influenced by the level of intermodal infrastructure integration, institutional coordination, regulatory harmonization, logistics system digitalization, and port operational performance. However, various previous studies have also revealed significant obstacles, such as limited supporting infrastructure, policy fragmentation, low interoperability of information systems, and weak coordination between stakeholders, which have resulted in increased logistics costs and delivery times. This study concludes that optimizing the multimodal maritime transportation system plays a strategic role in reducing export-import logistics costs, but requires an integrated and sustainable policy approach. The findings of this study are expected to provide a conceptual basis for formulating transportation and logistics policies and serve as a reference for further empirical research.

Abstract

Maritime higher education institutions face complex and multidimensional risks arising from academic activities, operational processes, maritime training practices, safety requirements, and regulatory compliance. Unlike conventional higher education institutions, maritime colleges are required to manage risks associated with shipboard training, simulators, laboratories, cadet discipline, and international maritime standards. This study aims to analyze the implementation of risk management in maritime higher education institutions and identify key risk categories, mitigation strategies, and governance mechanisms. Using a qualitative literature review approach, this study synthesizes findings from academic journals, international maritime organization reports, and regulatory frameworks published between 2020 and 2025. The results indicate that effective risk management in maritime higher education requires an integrated framework encompassing academic risk, operational risk, safety risk, compliance risk, and reputational risk. Institutional leadership commitment, risk-based governance, and digital risk monitoring systems emerge as critical success factors. This study contributes to the development of a structured risk management model tailored to the unique characteristics of maritime higher education institutions.

Abstract

Problem-solving ability is a core competence in mathematics learning and a key indicator of students’ higher-order thinking skills. However, many students experience difficulties in solving mathematical problems due to differences in prior knowledge, learning pace, and cognitive abilities. Adaptive Learning Systems (ALS) have emerged as an innovative instructional approach that personalizes learning experiences based on individual student needs. This study aims to examine the effectiveness of Adaptive Learning Systems in improving students’ problem-solving ability in mathematics. The research employed a quasi-experimental design with a pretest–posttest control group. The sample consisted of secondary school students divided into an experimental group using an Adaptive Learning System and a control group receiving conventional instruction. Data were collected through problem-solving tests and analyzed using descriptive and inferential statistics. The results indicate that students who learned through the Adaptive Learning System demonstrated significantly higher improvements in mathematical problem-solving ability compared to those in the conventional learning group. These findings suggest that Adaptive Learning Systems can serve as an effective instructional strategy to enhance students’ problem-solving skills in mathematics.

Abstract

Akademi Maritim Belawan tiffanybutarbutar22@gmail.com Abstract The fisheries sector plays an essential role in supporting the livelihoods of coastal communities. One of the major factors affecting fishermen's income is the effectiveness of operational fishing cost management. Poor cost management often leads to excessive operational expenditures, reducing net income despite favorable fishing yields. This study aims to examine the effect of operational fishing cost management on fishermen's income in Pantai Labu and Percut Sei Tuan Districts, Deli Serdang Regency, North Sumatra, Indonesia. This research employed a quantitative approach with an associative research design. The population consisted of 63 fishermen, while 51 respondents were selected using purposive sampling. Primary data were collected through structured questionnaires and analyzed using SPSS version 26. The analytical techniques included validity and reliability tests, classical assumption tests, simple linear regression analysis, and hypothesis testing using the t-test. The findings reveal that operational fishing cost management has a positive and statistically significant effect on fishermen's income. The regression equation obtained was Y = 3.376 + 0.729X, with a significance value of 0.000 (< 0.05). These results indicate that effective planning, recording, controlling, and evaluating operational fishing costs contribute significantly to increasing fishermen's income. Therefore, improving fishermen's financial management capabilities should become an important strategy for enhancing the economic welfare of coastal communities.

Abstract

The rapid digital transformation of the maritime industry has fundamentally reshaped the career orientation of maritime transportation students, shifting their aspirations from conventional employment in the shipping industry toward technology-driven entrepreneurship. This transition has created a new digital maritime business ecosystem that not only generates economic opportunities but also facilitates the social construction of entrepreneurial identity. This study aims to examine the process through which maritime transportation students construct their entrepreneurial identity within the digital maritime business ecosystem and to identify the internal and external factors influencing this process. A qualitative approach employing an interpretative phenomenological design was adopted. Data were collected through in-depth interviews with twelve maritime transportation students actively operating digital maritime businesses. Additional data were obtained from digital business documentation and observations of participants' social media activities. The collected data were analyzed using data reduction, thematic categorization, and contextual interpretation. The findings reveal that entrepreneurial identity develops through three interconnected stages: identity exploration, social legitimization, and entrepreneurial role internalization. This process is shaped by the interaction between personal motivation, entrepreneurial self-efficacy, supportive entrepreneurial communities, and the utilization of digital ecosystems, including social media and maritime digital business platforms. Furthermore, digital transformation within the logistics and shipping industries has significantly influenced students' career preferences by encouraging technology-based entrepreneurial activities. The study concludes that entrepreneurial identity in the context of digital maritime business represents a dynamic socio-digital construct emerging from the integration of entrepreneurial experience, digital presence, and ongoing industrial transformation. These findings contribute to the theoretical development of entrepreneurial identity research while offering practical implications for strengthening digital-based maritime entrepreneurship education in higher education institutions.
