Abstract

The lack of proper tourism infrastructure often limits the potential of marine ecotourism. In Karimunjawa, coral reef tourism is a major attraction. However, accessibility remains an issue, especially for visitors who cannot swim or dive. This research focuses on the design and construction of a glass-bottom leisure boat prototype to provide a safe and immersive underwater panorama experience. This study falls within naval architecture and marine engineering, addressing the challenge of designing a stable, efficient, and safe tourism vessel. A key concern in ship design is balancing hydrodynamic efficiency with stability. While monohull boats are common, their transverse stability is relatively low. To overcome this, a catamaran hull configuration was chosen for better stability, larger deck space, and reduced resistance. The prototype was constructed with dimensions of 21.81 m in length, 2.63 m in height, and 7.51 m in width, featuring a glass-bottom viewing area to enhance the tourism experience. Hydrodynamic performance analysis showed an average increase in resistance of 12.39307 N as speed increased, demonstrating the vessel’s efficiency. The construction and testing process confirmed that the catamaran hull improves passenger safety, minimizes capsizing risk, and enhances the underwater viewing experience. This research contributes to sustainable marine tourism by introducing an innovative tourism ride that allows visitors to explore the underwater beauty of Karimunjawa without requiring diving skills. The successful design and construction of this prototype provide a model for future eco-aafriendly tourism vessels.

Abstract

Gastronomi menjadi salah satu bidang unggulan Prancis terkenal di penjuru dunia, sehingga terdapat satu bidang khusus untuk mempelajarinya yakni français de la restauration et de la cuisine atau Bahasa Prancis bidang restorasi dan dapur. Bidang ini dipelajari salah satunya oleh siswa SMK jurusan Tata Boga. Banyaknya istilah universal di bidang ini seperti nama makanan, alat masak dan proses memasak yang berbahasa Prancis tidak serta merta dikuasai pengucapannya oleh siswa SMK. Permasalahan yang muncul adalah belum diberikannya pelajaran Bahasa Prancis khusus restorasi dan dapur kepada siswa jurusan Tata Boga di SMK Ibu Kartini Semarang karena tidak ada guru bahasa Prancis di sekolah tersebut. Kegiatan ini terfokus pada pelatihan terminologi kuliner dan penggunaan bahasa yang dilaksanakan untuk meningkatkan kemampuan bahasa dan pemahaman konteks siswa. Kemampuan mereka dalam menggunakan kosakata dan frasa yang tepat dalam konteks restorasi dan dapur direalisasikan dengan menggunakan 4 metode, yakni ceramah, drill, permainan dan praktik yang akan dilakukan secara rutin tiap pekan. Hasil akhir dari pelaksanaan kegiatan ini adalah bertambahnya pengetahuan para guru dan siswa tata boga SMK Ibu Kartini mengenai istilah bahasa Prancis yang sering digunakan di bidang gastronomi.
