This journal discusses the development of information systems that are interconnected and real time providing reports to all parties who need information. Overall, we find that the potential for oil sabotage is always present in the delivery of tankers from FPSO to shuttle tankers. The concept of integrated FPSO offloading management to tankers implies minimizing the potential loss of cargo. At the same time, the intelligent technology most often used to control maritime security is the Automatic Integrated System.","PeriodicalId":212685,"journal":{"name":"Maritime Park : Journal of Maritime Technology and Society","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116594465","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}

The goods transported are usually packaged goods. Using a bulbous bow on the ship's bow is the best alternative. Bulbous bows are installed on ships with high speed to reduce drag, whose nature depends on the function of the block coefficient and Froude number of ships. Ships with particular Cb and Fn can use a Bulbous bow due to considering the advantages of a significant enough resistance reduction, or vice versa. This research is a general cargo ship model with a bulbous bow. They are using the main dimensions of the ship with Length Over All (LOA) 153.45 m, Length Between Perpendicular (LBP) 144.2 m, Length On Load Waterline (LWL) 147.8 m, and Breadth (B) 25.27 m. height (H) 13.5 m, Draft (T) 9.52 m, Speed ​​(V) 14.75 Knots.

Adult lobsters can generally be found on a stretch of sand with coral spots with a depth of between 5-100 meters. This condition will cause a low number of young lobsters in the waters. This research was conducted with a case study regarding the policy of opening lobster seed export, which aims to find out how the policy is to open the export of lobster seed. The data obtained is done by reviewing the literature on the internet. Based on the analysis, the export profit of lobster seeds has continued to increase every month since it was again allowed by the government in May 2020. Based on data from the Central Statistics Agency (BPS), lobster seeds began to be re-exported in June 2020 at 32 kilograms, costing the US $ 112,990. The government can help with training and outreach on lobster cultivation. The government can offer Lobster a partnership package to help people start a freshwater crayfish business.","PeriodicalId":212685,"journal":{"name":"Maritime Park : Journal of Maritime Technology and Society","volume":"171 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123566355","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}

Fish catches from the Sunda Strait are landed in Pandeglang Regency, one of which is at the Labuan Coastal Fishing Port. The types of fish that are targeted for catching are mackerel and tuna. The high selling price of fish causes fishing operations to continue to be improved. Fishing operations that continue to increase can lead to a scarcity of fishery resources. Therefore, it is necessary to study the rate of fish resource utilization to determine their status. This study aimed to evaluate the rate of exploitation of tuna in the Sunda Strait based on fish catch data on 30 GT vessels and analyze it using policies issued by the Indonesian government. In this study, a simple linear regression method was used.
