Abstract

Central warehouse PT. X is a place to store materials needed for production. PT. X is a large company operating in the maritime and energy sectors. 5S work culture (Seiri, Seiton, Seiso, Seikatsu, Shitsuke) is a work culture adopted from Japan which aims to create an orderly work environment and increase safety, efficiency and reduce non-value added activities. The implementation of the 5S+Safety culture is implemented according to the SOPs in the central warehouse, but the implementation is not optimal. Implementation of the 5S+Safety method in the PT warehouse. X is considered not optimal because only 2S (Seiketsu and Shitsuke) is running well while 4S (Seiri, Seiton, Seiso, Safety) is not running well. Warehouse employees are advised to apply the 5R checklist and carry out routine independent audits which will be supervised by the department head. Therefore, this research was conducted to evaluate the implementation of 5S+Safety in PT. X’s central warehouse. Evaluation results using the 5S+Safety method support increasing company productivity and performance.

Abstract

The era of globalization has prompted countries, including Indonesia, to reconsider their defense capabilities in the face of increasingly complex threats. Indonesia's primary focus lies in the development of the maritime sector, given its strategic geographic position between the Pacific and Indian Oceans. Maritime security is crucial for smooth trade, considering that Indonesia is the world's second-largest producer of fish. The significant potential of marine resources requires attention to maritime security. Concurrently, globalization has altered the patterns and forms of threats, especially in international trade routes such as the Malacca Strait.This research employs the method of literature study to depict Indonesia's maritime conditions, infrastructure development, and the impact of globalization on maritime trade. The government's focus on enhancing logistical efficiency and infrastructure development aims to support industrial and trade growth. However, challenges persist, particularly in optimizing the management of marine resources and improving coordination among relevant institutions. In this context, Indonesia is presented with an opportunity to become a strong maritime nation with global competitiveness, supported by an active community and a profound understanding of its maritime identity. , , .

Abstract

The research method used was a qualitative experiment, starting with taking broken piston rings No. 2 and 3, cutting the piston rings and testing them with hardness tests and composition tests carried out at the Indonesian State Maritime Polytechnic and Undip Central Java Integrated Lab. From the results of this research, it can be concluded that the used broken ring number 3 has the highest hardness of 140.26 HB and the used ring number 2 is 131.50 HB, so it can be concluded that the piston ring that has been used and exposed to high heat causes an increase in hardness and causes it to break. The composition test results showed that the carbon content of the new ring no. 2 was the highest at 15.30% and that in the used ring no. 2 was 12.08% because the compression ring was in direct contact with the compression chamber or in contact with heat. For the used number 3 piston ring, the carbon content is 10.43 and the new one is 11.02 because it is positioned below the compression ring and is not in direct contact with heat. for the used ring no.2, the Silicon (Si) content is low, namely 2.15% compared to the new one, 2.75% because the nature of Silicium is that it is resistant to high temperatures and as a compression ring compared to ring no.3, fracture occurs because there are no Manganese or Phosphate elements. which is wear resistant, strong and elastic. The microstructure of piston ring No. 2 is broken and the new two piston rings are less dense and have rough gaps. The broken piston ring structure of No. 3 and the new one looks a bit gray and has high levels of graphite iron and carbon elements.

Abstract

Indonesia as an archipelagic country has very high resources in the fisheries and marine sectors, where these resources become weapons in improving the welfare of the people in particular and become capital in national development patterns. However, poverty is still an icon for fishermen. The income of fishing fishermen can be said to be different from other types of business because the fishing business is uncertain, where the income fluctuates and speculates, which can lead to the growth of poverty. The aim to be achieved in this research is to reveal and analyze things that influence the income of capture fisheries fishermen. Meanwhile, the author took the explanatory descriptive method as the research method. Data collection came from 100 fishermen respondents with discussion of fishermen's profiles in the form of age, education, family responsibilities, experience and length of time at sea.
