The system is designed using two models with the same specifications, each with an inlet cross-sectional area of 0.12 m2. The Francis turbine, with a turbine height specification of 0.3 m and a diameter of 0.576 m, is used to rotate the turbine blades, which can then be used to turn a generator to produce electricity for the power needs of a 6500 DWT tanker. The flow rate results show that the highest speed in the envelope of the seawater flow utilization system is 4,820 m/s with a water discharge of 0,578 m3/s. The power generated from one turbine from the system is 5,508 kW, while the electrical power generated is 4,710 kW. The computational fluid dynamic (CFD) method will be used to examine the velocity of fluid flow passing through the envelope of the seawater flow utilization system.\u0000 ","PeriodicalId":364471,"journal":{"name":"BAITA Engineering: Journal of Naval Architecture and Marine Engineering","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115746930","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}

This study aims to determine the calculation of the Production Cost of aluminum boats using the application of activity-based costing methods. As well as to find out the comparison of the calculation of the Production Cost of aluminum ships with traditional system methods and activity-based costing. At the data analysis stage, this study uses the activity-based costing method. The end result of this study is in the form of data from the results of data analysis from the application of the activity-based costing method, the advantages and disadvantages obtained while using this method. Based on the research results it can be concluded that by using the activity-based costing method, the company will get a positive impact in calculating the Production Cost in imposing factory overhead costs on each product.","PeriodicalId":364471,"journal":{"name":"BAITA Engineering: Journal of Naval Architecture and Marine Engineering","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127678161","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}

Barge is a type of ship with a flat hull or a large floating box, barges generally do not have a propulsion system but nowadays many barges have a propulsion system which is usually called a Self Propelled Barge. While barges are usually used to transport dry bulk goods or liquid bulk or recently also used to transport containers in connection with short sea shipping. So that in this study the aim is to design a general plan for room arrangement for the isolation room for COVID-19 patients. the need to design a room arrangement for the isolation room for covid-19 patients and the need to know the number of patients that can be brought. Equipped with several safety components, medical equipment, hospital facilities or a preventive measure that must exist in an emergency condition. The safety components on board must be managed as well as possible and must go through inspection procedures before being installed on the ship. This serves to ensure that everything is in good and optimal condition. This research will provide methods of data collection, design of plain lines and general plans, determination of load space capacity. The results obtained are barges with a capacity Alternative 1 patients amounted to 32 people and alternative 2 amounted to 48 people. From this capacity, the stability of the ship has met the requirements.","PeriodicalId":364471,"journal":{"name":"BAITA Engineering: Journal of Naval Architecture and Marine Engineering","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123309075","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}

Hazards are identified using HAZOP (hazard and operability) while the frequency of hazard is conducted by means of fault tree and event tree analysis. The consequence of hazards is analyzed using process hazard analysis tools and risk is represented in F-N curve according to Hongkong Government Risk Guidelines (HKRG). Five leak diameter scenarios were examined resulting that two hazards are potentially occur during the ammonia loading process such as gas dispersion and explosion. According to the result of frequency and consequence analysis, those hazards is laid in ALARP (as low as reasonably practicable) region, hence there is no mitigation necessarily to be taken. However, for the safe operation, the company should ensure that the risks will not move to unacceptable region by performing routine maintenance and all safety procedures established by the company were well implemented.","PeriodicalId":364471,"journal":{"name":"BAITA Engineering: Journal of Naval Architecture and Marine Engineering","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129012779","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}

By using the regression method, an analysis of the technical data of existing tugboats is carried out. The data is obtained by collecting data on tugboats that are registered and in operation, including as many as 381 tugboats. From the results of the analysis carried out, it was found that the relations model power propulsion to hull forms is parametric, and the model was validated by testing the existing tugboat to determine how many errors the relations model has. Based on the results of the analysis carried out, power propulsion affects the hull forms parametric, where the increase in power propulsion will increase the value of the hull forms parametric, in this case the main dimension of the tugboat (L, B, D, and T). The value of power propulsion in the main dimension of a tugboat has a different effect on each type of tugboat.","PeriodicalId":364471,"journal":{"name":"BAITA Engineering: Journal of Naval Architecture and Marine Engineering","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125814440","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}
