This study aims to develop an effective seafarer competency improvement model in reducing turnover rates in the Indonesian maritime industry. The research method used is a mixed-method with a quantitative and qualitative descriptive approach. Data collection was carried out through questionnaires, interviews, and documentation studies of 150 seafarers from five national shipping companies. The Technology Readiness Level (TRL) of the proposed model was evaluated at TRL 7, indicating that this model has been tested in a limited operational environment with adequate results. The results showed that 65% of seafarers felt they did not receive adequate competency-based training, while 48% of them indicated a desire to change jobs shortly. The competency improvement model, designed based on digital technology and simulation-based training, succeeded in increasing the average competency score of seafarers from 68% to 85% within six months. In addition, the turnover rate of the company that became the pilot project for this model decreased from 22% to 14%. This study offers a state-of-the-art in the form of an integration of competency-based approaches with digital technology, different from previous studies that focused on conventional interventions. The novelty of this study lies in the use of a digital-based model that combines continuous evaluation and adaptive training programs that are tailored to the needs of individual seafarers. This model is expected to be a strategic solution to increase seafarer retention in the maritime industry while strengthening the competitiveness of the Indonesian workforce in the international market.

Sharia Securities-based crowdfunding (Sharia SBC) has emerged as a novel financial innovation that integrates Islamic principles with financial technology, expanding investment access in Indonesia. However, this development has also created significant regulatory gaps and legal risks related to data protection, Sharia compliance, information asymmetry, and weak dispute resolution mechanisms. This study examines the adequacy of Indonesia’s dual regulatory model, the Financial Services Authority (OJK) and the National Sharia Council (DSN-MUI), in protecting investors and ensuring Sharia compliance in SBC. Using normative legal methods combined with comparative and policy-oriented approaches, the study identifies the lack of binding force in DSN-MUI fatwas, the limited role of the Sharia Supervisory Board, and weak enforcement of data security and disclosure standards. Comparative studies from Malaysia and Bahrain suggest that integrating Sharia audits and a centralized dispute resolution mechanism can strengthen legal certainty. These findings underscore the need for regulatory reforms to render DSN-MUI fatwas legally binding, establish a Sharia arbitration body, and mandate annual Sharia compliance audits for SBC operators. These recommendations aim to improve legal certainty, investor protection, and the integrity of Shariabased financial technology in Indonesia.

This study examines the association between Bridge Simulator training, seafarers’ self-awareness, and emergency decision-making performance. A quantitative correlational design was employed involving 105 active seafarers who had participated in certified bridge simulator training. Data were collected using a structured questionnaire measuring perceived training quality, self-awareness, and emergency decision-making performance. Spearman’s rho correlation analysis revealed a strong positive association between Bridge Simulator training and self-awareness (ρ = 0.764), as well as between Bridge Simulator training and emergency decision-making performance (ρ = 0.744). These findings indicate that higher perceived quality of simulator training is associated with higher levels of self-awareness and decision-making performance in emergency contexts. The study contributes empirical evidence on the psychological and cognitive dimensions associated with simulator-based maritime training and highlights implications for maritime education and safety training.
