The pump moves fluid from a low pressure place to a place with a higher pressure, to overcome this pressure difference a power is needed. The cooling system is a system that serves to keep the engine temperature in ideal conditions.Seawater cooling pump used on the MV.BAHARI 22 ship, experienced a problem of decreased suction power analyzed using quantitative research methods in which research uses data taken directly on the ship. Then the analysis of this study uses a predetermined formula. Research findings and analyzed data are head loss which includes static head, head pressure, head speed, head major loss, head minor loss. \u0000The decrease in the pressure of the sea water coolant pump on the ship is caused by the total head of the system which exceeds the pump head where the head of the system according to the calculation is 61 m, while the maximum head of the pump is only 55 m so that the cavitation in the pump is ensured which causes impeller damage and damages the house the snail This can be proven from the calculation results where the NPSHr value = 5.49 meters far exceeds the NPSHa value which is only 2.52 m.","PeriodicalId":308610,"journal":{"name":"JURNAL JALASENA","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128414681","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}

Hal ini mengakibatkan penumpang yang seharusnya turun dari kapal menjadi naik dari kapal, dan harus di tarik dari kapal ke atas ponton. Jumlah kapal yang berlabuh di ponton Sri Tanjung Gelam sebanyak 24 kapal setiap harinya. Dari data yang di kumpul penulis free board kapal yang ada berkisar antara 800mm sampai 1000mm, maka penulis melakukan desain ulang dan menetukan rata-rata free board kapal tersebut sebesar 900mm. Ponton ini secara perhitungan dan design menghasilkan free board yang tepat seperti yang direncanakan yaitu tinggi 1400mm, draft/ saratnya 500mm, dan free board 900mm. Ketinggian ponton yang ada saat ini 2000mm dengan Sarat 600mm Free board nya 1400mm. Kesalahan pada perencanaan sebuah ponton akan menimbulkan dampak yang serius terhadap keselamatan pengunaannya. Dari data perbandingan ukuran ponton baru dan ponton lama di atas bisa didapatkan penghematan pemakian material dari ponton lama. Pentingnya perhitungan draf atau free board ponton yang tepat akan memberikan keuntungan baik dari segi keselamatan pengguna maupun pembiayaan pembangunannya.","PeriodicalId":308610,"journal":{"name":"JURNAL JALASENA","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123363852","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}

Kapal fast monohull memiliki desain yang dirancang sedemikian rupa untuk mencapai kecepatan yang diinginkan. Dalam pembuatan sebuah kapal selalu memperhatikan parameter- parameter desain desain yang direncanakan juga pertimbangan sisi ekenomis. Dalam hal bentuk lambung, kapal fast monohull sudah berkembang dengan memiliki berbagai macam konfigurasi. Salah satu konvigurasi bentuk lambung yang cukup populer belakangan ini adalah bentuk ‘Axe Bow’ yang di desain oleh Delft University of Technology (TU Delft) dan Maritime Research Institute Netherlands (MARIN). Keunikan dari konvigurasi lambung ini adalah bentuk bow (haluan)-nya yang tegak lurus kedepan menyerupai kapak yang diklaim memiliki performa hidrodinamis yang baik. Pada penelitian ini dilakukan analisa hambatan terhadap bentuk lambung kapal patroli dengan konvigurasi perubahan sudut lambung yang mendekati tegak lurus hingga tegak lurus. Dan mendapatkan hasil bahwa sudut kemiringan 90’ pada bow memberikan aspek hidrodinamis yang paling baik diantara variasi lainnya dengan hambatan total (Rt) senilai 474.8 kN dengan metode Holtrop, 604.8 kN dengan metode Compton dan 633.4 kN dengan metode Fung.","PeriodicalId":308610,"journal":{"name":"JURNAL JALASENA","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114752614","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}
