Abstract

The Riau Archipelago is one of the provinces that geographically consist of 1700 islands surrounded by sea, both small and large, with a percentage of 98% sea and 2% land. So, to support the minimal health facilities on the Riau Archipelago, an Ambulance Boat is needed to mobilize patients to hospitals with better facilities. In this study, it aims to modify the design of the High Speed Landing Craft Boat Passenger to become an Ambulance Boat with a length of 12 m, a width of 3 m, a height of 1.2 m, and a draft of 0.6 m. Then perform technical calculations including hull shape coefficient analysis, stability, seakeeping, resistance, speed, ship power, and Motion Sickness Incidence (MSI) analysis. From MSI analysis with ISO 2631 parameters, the wave heading is divided into 5 sections: 00 (Following Seas), 450 (Stern Quartering Seas), 900 (Beam Seas), 1350 (Bow Quartering Seas), and 1800 (Head Seas). The value MSI is obtained after carrying out a comprehensive analysis, the results are depicted in the MSI chart for sea state 1 calm (0-0.1 m) and sea state 2 smooth (0.1-0.5 m) conditions with the following wave directions, waves coming from the side (beam seas), and waves coming from the front (head seas).

Abstract

Riau Islands Province as a maritime region is known for its marine tourism and tourist attraction on small islands. Answering the current challenges in tourism sector of Riau Islands Province is through the support of reliable and eco-friendly infrastructure to support attractiveness of marine tourism especially in terms of tourism ship design. The aim of this research is to design energy efficiency tourism ship by applying renewable energy using solar panels that can reduce exhaust emission and energy efficiency. Innovation of energy saving tourism ship was designed by analyzing the maximum GZ stability at 2,603 m at 67.3 degrees at the ship's maximum draft. By utilizing bottom glass platform technology that can directly see underwater coral reefs, this tourism ship has become a ship with the latest innovations with the application of renewable energy technology that answers the challenges of tourism strategies in the Riau Islands Province region.

Abstract

The operational efficiency and safety of patrol vessels critically depend on minimizing hydrodynamic resistance and enhancing seakeeping performance. This study explores the effect of stern foils with different NACA airfoil sections on a patrol vessel. Employing Computational Fluid Dynamics (CFD), we assessed water resistance in calm conditions and seakeeping traits in regular head seas. Based on the results obtained, the total resistance value (RT) without stern foil shows a value of 202,112 N. Findings show that stern foils lead to a considerable reduction in total resistance, with the NACA 2412 profile achieving the greatest reduction at 14.85%, followed by NACA 64-212 (14.70%) and NACA 4412 (11.67%) at 20 knots and Fn 0.418. Additionally, seakeeping assessments revealed a significant mitigation of pitch and heave motions across all foil designs, notably a marked decrease in pitch Response Amplitude Operator (RAO) at the dominant frequency of 0.13 Hz. This work provides significant contributions to the optimization of patrol vessel design through advanced hydrodynamic additions, contributing to better fuel economy and greater operational stability in challenging maritime environments.

Abstract

Literasi teknologi merupakan salah satu kompetensi kunci abad ke-21 yang perlu ditanamkan sejak pendidikan dasar. Namun, masih banyak siswa sekolah dasar yang belum terbiasa menggunakan teknologi dalam konteks pembelajaran. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengenalkan media pembelajaran flipbook terintegrasi Augmented Reality (AR) kepada siswa SD Negeri 010 Kota Tanjungpinang sebagai upaya penguatan literasi teknologi. Kegiatan dilakukan melalui pendekatan sosialisasi, demonstrasi langsung, dan evaluasi sederhana. Hasil kegiatan menunjukkan bahwa siswa mampu memahami konsep dasar penggunaan teknologi dalam belajar, serta menunjukkan antusiasme tinggi terhadap media pembelajaran flipbook AR. Visualisasi objek digital yang ditampilkan dalam media flipbook AR terbukti meningkatkan motivasi dan antusian siswa untuk terlibat dalam proses pembelajaran. Selain itu, guru menunjukkan ketertarikan terhadap penggunaan media serupa dalam proses belajar-mengajar dan menyampaikan perlunya pelatihan lanjutan. Temuan ini mengindikasikan bahwa flipbook AR memiliki potensi besar sebagai media pembelajaran interaktif yang dapat mendukung transformasi digital di lingkungan pendidikan dasar. Diharapkan kegiatan ini dapat dikembangkan lebih lanjut sebagai bagian dari strategi inovasi pembelajaran yang berkelanjutan.

Abstract

The increasing demand for energy and the continued reliance on fossil fuels in Indonesia present serious environmental and economic challenges. This community service project introduces an innovative solution by developing bio-briquettes from cassava peel waste in South Toapaya Village, Bintan Island. The program applies a Participatory Action Research (PAR) approach to engage the community in a hands-on learning experience, from problem identification to production and evaluation. Through interactive socialization and technical training, villagers—especially farmers and housewives—were educated on the benefits of converting plantation waste into renewable energy. The process involved drying, pyrolysis, mixing with natural adhesives, molding, and testing of the resulting briquettes. The produced bio-briquettes demonstrated effective burn duration up to 42 minutes with low smoke output, making them a viable alternative to firewood. This initiative not only reduced organic waste but also empowered the community to create economic value from local resources. While the project achieved its educational and technical goals, limitations included a lack of laboratory validation and small-scale outreach. The results show promising potential for broader implementation in rural energy innovation.

Abstract

ABSTRACT – Longitudinal strength is a fundamental aspect of barge structural safety because variations in loading magnitude and load position may significantly affect the global hull girder response. This study aims to evaluate the longitudinal strength of a cargo barge based on shear force and still water bending moment under various loading conditions. The object of the study is a cargo barge with principal dimensions of 330 ft × 90 ft × 21 ft and a lightship weight of 1802.9 tons. The analysis was carried out using a still-water longitudinal strength approach based on the distribution of weight and buoyancy along the vessel length. Six loading conditions were investigated, namely lightship, fully loaded, partially loaded at 50%, and three crane-shift positions at the aft, midship, and fore sections. The net load distribution was obtained from the difference between distributed weight and buoyancy, and then integrated to determine the shear force and still water bending moment along the hull. The results show that the fully loaded condition produced the most critical structural response, with a maximum shear force of 0.385 × 10³ ton at Frame 50 and a maximum still water bending moment of -6.212 × 10³ ton·m at Frame 35. In contrast, the lightship condition generated the lowest internal force response. All evaluated loading conditions remained below the permissible shear force and still water bending moment limits, indicating that the barge satisfies the applicable longitudinal strength requirements. The study concludes that the vessel is structurally acceptable under all investigated loading scenarios, with the fully loaded condition representing the governing case for safe operation and load planning.
