<![CDATA[The perpose of this study was to determine the effect of motivation and psychological contracts on job satisfaction and its implications for employee performance at the Bumi Akpelni Polytechnic Semarang. This study is a quantitative descriptive study with a sample of 68 employees. The dependent variable in this study is job satisfaction and performance, while the independent variables are motivation and psychological contract. In this study using the method of purpose sampling as a sampling technique. The results of the study explain that the psychological contract variable has a t-count calculation (0.538) with a significance (0.000 <0.05) so it can be concluded that the psychological contract variable has a positive and significant effect, while the motivation variable has a result with a path calculation of (0.028). it means that the motivation variable is also said to have a positive effect through job satisfaction. It is explained in the first equation that the adjusted R2 square is 0.057 meaning 5.7% of the job satisfaction variable can be explained by the variation of the two independent variables, namely work motivation and psychological contract, while 94.3% is explained by other reasons outside this research model. in the second equation it is stated that the adjusted R2 square is 0.265, meaning that 26.5% of the performance variable can be explained by the psychological contract variable, while the remaining 73.5% is explained by other reasons outside this study.]]>

<![CDATA[Along with the development of increasingly sophisticated technology, vessels as means of transportation at sea have progressed a lot. There is a part of activities aboard vessel which determines the effectiveness of every voyage of the vessel which is communication aboard vessel. Communication which occurs intensively and properly leads to effective communication. In radio communication committing flouting maxim of conversation could not be avoided. The radio communication context plays significant role to interpret the meaning of the speech itself. This study aims to determine the conversational implicature used aboard vessel and the flouting maxims which arise especially from the external radio communication. The design of the research was descriptive qualitative in which the data were taken from the radio communication among cadet’s radio communication practice in bridge simulator. The finding shows that the four types of maxim flouting were committed by the duty officers on radio communication. The highest maxim flouted was flouting maxim of quantity as much as 36,3%. The less frequent maxim to be flouted was maxim of manner and quality as much as 18,2%. The other 27,3% was the occurrence of flouting maxim of relevance. The rationales behind the flouting maxims were also revealed in this study to get the knowledge and best practices onboard radio communication.]]>

<![CDATA[There are five main components that affect port performance, namely: Ship movement, labor productivity, equipment, cargo intensity at moorings, and cargo flow intensity at storage locations. (media.neliti.com, 2019). These five components affect the effectiveness of loading and unloading activities at the port. In analyzing the data the author uses qualitative methods in analyzing a data that is in the field. Factors that greatly affect delays or hinder unloading activities are when the process of unloading cargo; the ship performs ballast; bad weather. General Cargo's unloading process performs with cargo safety guidelines, which prioritize safety in loading and unloading performance, namely to cargo. Every ship is more concerned with work safety, but on the other hand, the ship is more concerned with cargo safety when operating the unloading to the dock or to the barge.]]>
