<![CDATA[Adolescence represents a critical stage of physical and cognitive development, requiring balanced nutrition to support growth, concentration, and academic performance. However, many students still lack awareness of healthy dietary practices and continue to consume nutrient-poor foods, leading to increased risks of metabolic and cognitive disorders. To address this issue, a dual-focus educational program was implemented at SMA Negeri 6 Penajam Paser Utara, combining balanced nutrition education with the introduction of simple renewable energy technology through biodiesel production from waste cooking oil. The program, conducted in collaboration with the Kalimantan Institute of Technology (ITK), employed interactive lectures, demonstrations, and hands-on sessions to enhance student understanding. A pre-test and post-test evaluation involving 40 students demonstrated a substantial improvement in knowledge, increasing from 45% to 96% after the intervention. Participants also expressed strong positive responses to the integration of nutritional awareness and eco-friendly technology, recognizing its relevance to daily life and environmental sustainability. The results show that this dual educational approach effectively strengthens students’ understanding of healthy eating habits while promoting environmental responsibility through waste-to-energy concepts. Overall, the program highlights the potential of combining nutrition education and renewable energy literacy as a strategic model for school-based community outreach aimed at fostering healthier, more environmentally conscious future generations.]]>

<![CDATA[Patrol boat play a crucial role in maritime security and law enforcement, where optimizing hull performance is essential to achieve both efficiency and stability in various sea states. This study analyzes the influence of hard chine variations on the resistance and stability of a patrol boat hull. Four hull models single and double chine with angles of 0° and 10° were evaluated using Maxsurf Resistance and Stability. Total resistance was calculated at service speeds of 10 and 15 knots, while stability was assessed based on IMO Resolution A.749(18), Chapter 3. Results show that at 10 knots, the single chine 10° model produced the lowest resistance, whereas at 15 knots, the double chine 10° gave the best performance. Stability analysis indicated that all models met IMO criteria, with the double chine 10° achieving the highest GMt, maximum GZ, and angle of maximum GZ. The findings suggest that the single chine 10° is more efficient for calm-water operations, while the double chine 10° provides superior stability for rough-sea conditions]]>

<![CDATA[Ship docking operations require careful planning and precise implementation to ensure safety and operational efficiency. One widely applied method in shipyard practice is the use of marine airbags to support vessels during docking and undocking processes. This study analyzes the application of a marine airbag-assisted docking system for the barge BG. Liana at PT. Jhonlin Marine Trans using an analytical and field-based approach. The analysis focuses on determining the required number of airbags, evaluating load distribution, and identifying factors contributing to airbag failure during docking operations. Vessel principal dimensions and marine airbag specifications were used as primary input parameters, while field observations were conducted to assess actual operational conditions. The results indicate that a minimum of 21 marine airbags is required to ensure adequate load sharing and structural safety; however, only seven airbags were deployed in practice, leading to excessive load concentration and increased risk of airbag failure. The failure analysis demonstrates that the observed damage was predominantly caused by controllable operational factors, including inadequate airbag quantity, improper placement, pressure inconsistencies, and runway conditions. These findings highlight the importance of strict compliance with analytical planning and operational procedures to enhance safety and reliability in marine airbag-assisted docking operations.]]>

<![CDATA[The Indonesian maritime industry faces a critical human capital paradox, where a surplus of vocational graduates exists alongside persistent difficulty among shipyards in recruiting personnel capable of executing modern Product-Oriented Work Breakdown Structure and digital drafting workflows. This study investigates this disconnect through the pilot implementation of an Applied CAD for Maritime Engineering curriculum at a partner vocational high school, SMKN 5. Using a Guided Replication methodology, the intervention bridged the gap between theoretical software knowledge and industrial application by emphasizing parametric modeling and design-for-production logic. The results show that student aptitude is high, as evidenced by the rapid acquisition of three-dimensional modeling skills, while the national vocational infrastructure remains critically unprepared. The study identified a significant technological readiness gap in which existing school hardware was unable to support industry-standard software, requiring external technical intervention. These findings indicate that closing the maritime skills gap requires more than curriculum reform alone, but also necessitates fundamental improvements in school computing infrastructure and a pedagogical shift from software-centric instruction toward production-centric learning. This research proposes a scalable framework for integrating industrial competencies into vocational education to support the long-term development of Indonesia’s maritime workforce.]]>

<![CDATA[The use of synthetic fibers in composite materials in the shipping industry provides mechanical advantages but produces non-biodegradable waste. This encourages the development of more environmentally friendly natural fiber-reinforced composite materials. This study examines the physical properties and tensile strength of composites made from a mixture of coconut petiole fibers and fiberglass, including the effect of immersion in seawater and freshwater for 30 days. The results show that the composites experience an average water absorption of 0.074% (freshwater) and 0.065% (seawater). Tensile tests show average tensile strength values of 35.837 MPa (freshwater), 31.890 MPa (seawater), and 41.290 MPa (without immersion). Immersion in an aqueous medium reduces the tensile strength due to interfacial degradation between the fiber and the matrix. Coconut petiole fiber–fiberglass composites have the potential to be an alternative material for ship components with competitive and environmentally friendly mechanical characteristics]]>
