It can result in symptoms of illness or an uncomfortable atmosphere for passengers on board. This symptom is often referred to as seasickness or motion sickness. The main cause of seasickness is the absence of similarity of excitability or conformity between the stimulus, eye and ear labyrinth the human brain receives. Usually, people who get seasick are on closed decks because their eyes cannot see any movement. At the same time, the ear labyrinth responds to the ship's movement so that there is a conflict between the stimuli received by the eyes and the ear labyrinth, which is responsible for body balance, causing nausea. In severe cases, passengers or crew must be taken to the hospital. Modelling MSI on Finite Element Method Software, it can be seen that passengers experience ship sickness or, in this case, experience MSI at what time on a cruise on the Cilacap sea lane processed to determine the condition of the ship's MSI to passengers by the acquisition of 6 degrees of freedom where various components that affect such as wind, the main current is a wave it occurs 6 degrees of freedom, i.e. Surging is a translational movement along the X axis, Rolling is the movement of the ship around the X axis, Swaying is the translational movement of the ship that occurs when the ship moves along the Y axis, Pitching is the movement of the ship around the Y axis, Heaving is the movement of the ship along the Z axis. A ship with a speed of 12.5 knots sailing in the Cilacap sea with a wave height reaching an average wave of 2.5 meters, the MSI of the ship occurs, namely the effect of sea conditions on the movement of the ship indicating that the ship's response to the sea is at 90 degrees. In the opposite direction of the wave, MSI occurs in 20% of passengers after 2 hours on the vehicle deck at the bow point. At that time, the magnitude of the encounter frequency was 2.137 Hz.","PeriodicalId":212685,"journal":{"name":"Maritime Park : Journal of Maritime Technology and Society","volume":"39 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":"116901086","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}

While all stakeholders or stakeholders expect the success of tourism which contributes to economic improvement, community welfare, human resource development, and improvement of public health and the environment, tourism activities on Kayangan Island need clean water for their development. Considering that the island is one of the favourite tourist destinations and is growing quite rapidly at this time, there is no effective source of clean water available on the island. Therefore, it can be attempted to provide clean water by using subsea pipes sourced from PDAM Makassar. According to observations from various aspects, the pipe will cross the ocean with a span of ±1500 meters by flowing water with a discharge of 10 lt/s using HDPE pipes with a diameter of 140mm PE100, PN 16 according to SNI standards. For a fairly good security system, the jet pump and the pipe will be tied to a 110 mm diameter stainless steel sling bridge. In addition, at every 6 meters distance, the pipe bridge slings are fitted with ballast loads with hanging slings. In this study, the installation of subsea pipelines requires a variety of supporting equipment and also a complicated implementation, but it is can be carried out considering this needs to be done to support the need for clean water on Kayangan Island to support tourism development.","PeriodicalId":212685,"journal":{"name":"Maritime Park : Journal of Maritime Technology and Society","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126786165","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}

In recent years, the condition of the Kenjeran Beach area has experienced a decline in tourists. Given that, for several years there have been no significant changes in the development of the Kenjeran Beach area. For Kenjeran tourism to be more optimally developed, it is necessary to integrate and integrate many objects and tourist attractions in one area. The method used is the descriptive qualitative method. The results of the study describe the potential of the Kenjeran coastal area and then several policies that have been carried out by the government to develop the Kenjeran coastal area along with several impacts or conflicts on the local community. The cable car development policy for Kenjeran coastal tourism is very beneficial for the lives of coastal communities in the tourism sector and the economic life of the local community. However, the development only knocked down three fishing posts, which disturbed the people who had previously supported them. Although in the end the three posts were rebuilt in making policies, it is necessary to pay attention to no more losses on the one hand. Furthermore, the Bulak Fish Center policy whose impact is very beneficial for the survival of the Kenjeran coastal community because it is a form of livelihood so economic growth is very rapid. There are still many efforts that can be made for the implementation of policies on the Kenjeran coastal area to be more developed, but in that case, it needs to be analyzed again so that the policy is implemented properly.","PeriodicalId":212685,"journal":{"name":"Maritime Park : Journal of Maritime Technology and Society","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128926792","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}
