Unfortunately, this vast potential has not yet been utilized optimally in the Indonesian seas. Ocean wave energy technology has developed rapidly in various countries worldwide. One of the most famous ocean wave power generation technologies is the Oscillating Water Column (OWC), which utilizes airflow from ocean waves oscillating movement. Inspired by OWC, an innovative ocean wave power generation technology model was designed using a simpler fan turbine because it is directly integrated with an electric dynamo and an internal flow system in a venturi tube which can increase airspeed based on the concept of continuity theory. The experiment's results succeeded in creating up and down movements of ocean waves with a high tide of 15 cm and a low tide of 12 cm. Ocean wave oscillations can produce gusts of air with a speed of 1.56 m/s. The final result is obtained by model performance with an average turbine rotation speed of 42.191 rpm, an average electric voltage of 0.809 volts, and a more optimal turbine efficiency of 67.9%.","PeriodicalId":263381,"journal":{"name":"Wave: Jurnal Ilmiah Teknologi Maritim","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135619304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the type of sail propulsion has been found since time immemorial, research on sails and their effects on sailboats is very rarely done. In general, research only focuses on calculating the size of the sail so that the sailboat is able to go at the desired speed without considering other things that might happen to the sailboat if the sail is used. Therefore, the researcher intends to analyze the force on the sail with variations of the sail and ring and its effect on the sailboat. Based on the results of the research conducted, taking into account the wind conditions in the coastal area of Banyuwangi, the results of the data analysis are as follows, including the size of the main sailing vessel that is suitable for having a length of 5 meters, a width of 2 meters and a height of 1 meter and a water laden depth of 0 ,5 meters. The best wind direction is at 180° or behind the sail boat. The optimum wind speed that can be used is 30 knots or 15 m/s. And the maximum heeling degree that can be tolerated before the sail boat is 25° Direction of port side and right.","PeriodicalId":263381,"journal":{"name":"Wave: Jurnal Ilmiah Teknologi Maritim","volume":"288 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136381218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Riset dilaksanakan menggunakan Finite Element Analysis dengan pemodelan menggunakan bantuan software Ansys. Model ladder dibuat sesuai aktual dengan panjang ladder 59 m. Kemudian dibuat masing-masing model diagonal bracing dan x-bracing khusus pada konstruksi pondasi katrol. Beban yang bekerja pada ladder untuk 2 model sama yaitu berat pipa dan lumpur sebesar 1,42 x 105 N, berat cutter sebesar 0,57 x 105 N dan torsi cutter sebesar 0,67 x 108 Nmm. Hasil analisa menunjukkan bahwa tegangan maksimum terjadi pada komponen strut tepat dibawah pondasi katrol untuk model diagonal bracing sebesar 57,32 N/mm2 dibandingkan dengan model x-bracing sebesar 25,44 N/mm2. Hasil ini menunjukkan bahwa konstruksi brace yang dipasang pada area katrol ladder sangat mempengaruhi nilai tegangan sehingga untuk meminimalisir kegagalan struktur ladder khususnya pada area katrol sebaiknya menggunakan konstruksi x-bracing karena memiliki nilai tegangan minimum dibandingkan konstruksi diagonal bracing yang terpasang saat ini pada Kapal Isap Produksi.","PeriodicalId":263381,"journal":{"name":"Wave: Jurnal Ilmiah Teknologi Maritim","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126420719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Berdasarkan hipotesa, hal ini disebabkan oleh gaya angkat yang diberikan Hull Vane® terlalu besar sehingga kapal mengalami trim haluan. Untuk mengurangi trim haluan maka dibuat ukuran Hull Vane® yang lebih kecil antara lain Hull Vane® dengan AR = 8.5, AR = 22.9 dan AR = 28.94 dengan kecepatan uji pada 11 knot (Fn = 0.34), 17 knot (Fn = 0.53), 20 knot (Fn = 0.62) dan 26 knot (Fn = 0.8). Dari hasil simulasi yang dilakukan, didapatkan bahwa penggunaan Hull Vane® lurus di setiap variasi aspect ratio pada kapal uji hanya efektif pada kecepatan 11 knot dimana mampu mengurangi resistance kapal hingga 17%. Untuk kecepatan di atas 11 knot, peningkatan aspect ratio mampu untuk mengurangi hambatan namun resistance pada kapal dengan Hull Vane® lurus masih lebih besar dibandingkan dengan kapal tanpa Hull Vane® yang disebabkan nilai lift force oleh Hull Vane® lurus pada buritan kapal masih terlalu besar sehingga haluan kapal lebih banyak tercelup dibandingkan kapal tanpa Hull Vane®. Hal tersebut mengakibatkan nilai wetted surface area (WSA) dan nilai hydrodynamic pressure meningkat dibandingkan kapal tanpa Hull Vane® sehingga nilai resistance kapal pun bertambah.","PeriodicalId":263381,"journal":{"name":"Wave: Jurnal Ilmiah Teknologi Maritim","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129495335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aktifitas perekonomian antar pulau, masyarakat secara umum menggunakan transportasi laut berupa kapal pelayaran rakyat (Pelra), kapal penyeberangan berukuran kecil dan kapal perintis. Pada penelitian ini dilakukan studi konseptual perencanaan fasilitas transportasi laut berupa waterbus yang bertujuan untuk meningkatkan kemudahan akses kegiatan ekonomi masyarakat kepulauan kangenan. Metode yang digunakan pada penelitian ini berupa studi lapangan untuk mengetahui pola operasi kapal serta menggunakan data kapal pembanding yang beroperasi di Kepulauan Kangean. Berdasarkan hasil studi lapangan diperoleh bahwa mayoritas kapal yang melayani pelayaran di kepulauan kangenan adalah kapal pelayaran rakyat. Hasil regresi linear diperoleh ukuran utama kapal Waterbus adalah L=15 m, B=4 m, H=1,71 m, T=0,86 m, GT=16,71 ton.
