Salt is a strategic resource or commodity with great potential and has not been appropriately managed. Indonesia, with a potential coastline of 81,000, has great potential to become a salt-exporting country, but currently, to meet the national salt demand, Indonesia must import salt. The right solution is needed to eliminate the problem of importing salt that occurs. The concept of the Blue Economy, which prioritizes economic growth from the marine and fisheries sector while ensuring the sustainability of resources and the coastal and marine environment, is closely related to the current salt import policy. This study aims to analyze the policy of importing salt from other countries to Indonesia as a threat or opportunity to realizing a Blue Economy in Indonesia. The method used in this study is a qualitative approach and the analysis used is PESTEL. It is recorded that 20 factors represent opportunities to import salt and 15 factors that threaten salt import. Even so, the study results show that the score for import opportunities is lower than the threat. From the score obtained, it can be concluded that although many factors encourage Indonesia to import salt, the urgency for Indonesia to import salt is still not too strong. This policy-making must be in line with the Blue Economy concept, which emphasizes the benefits and impacts of achieving welfare for the community. There needs to be a government policy to increase national salt production to suppress the increasing number of salt imports. The critical factor for its success is increasing the amount of domestic salt production. In the future, the results of this study can be used as material for consideration by the Indonesian government in developing national salt production

Bengkalis Regency is located on the north coast of Riau Province, where the coastal area is very vulnerable to the threat of maritime disasters. Global warming can result in natural disasters, which means catastrophe on earth. Global warming causes an increase in the temperature of the earth's surface. This study aims to analyze the progress of the coastline and sea level rise that occurs and their impact on the degradation of Mangrove land on the north coast of Bengkalis Island, Riau Province. The research method used is the quantitative method through analysis of satellite images to map predictions of abrasion in the future. Data processing is carried out using satellite image data with different temporal, namely 1991, 2002, 2012, and 2021. Analysis of shoreline change predictions is carried out using the Digital Shorelines Analysis System Method. Utilization of GIS data can be used to map areas with the potential for abrasion, and make anticipatory measures against abrasion that may occur. In Bengkalis Regency itself, several efforts have been made by the local government, namely through mangrove planting programs, and increasing public awareness.

This study aims to analyse the changes in the coastline that will occur using geographic information system technology and formulate anticipatory efforts from the government to overcome the threat of abrasion on the north coast of Bengkalis Island, Riau Province. Bengkalis is a Regency located on the north coast of Riau Province, where the coastal area is very vulnerable to maritime disasters. This is evidenced by tidal waves or high tides that regularly occur at the end of the year in the north coastal area of the Bengkalis Regency. There are hundreds of houses and shopping centre shops submerged by the tide; this is causes harm to the community. In addition, the threat of abrasion, which causes changes to the coastline toward settlements, continues to increase every year; this problem threatens the country’s sovereignty because the worst possibility is to eliminate the island. This study found that coastal abrasion that occurred on the coast of Bengkalis Island reached 39 meters a year, and the average rate of change of the coastline was 14 meters a year.Without serious handling and countermeasures from the government, this will become a big problem.

Leadership can be seen as an instrument in an effort to influence and control a person or group of people to cooperate in achieving certain goals. The Blue Economy is expected to be able to answer the dependence between the economy and the ecosystem as well as the negative impacts of economic activities including climate change and global warming. The principles contained in the blue economy can be a golden key in national development planning. The purpose of this study is to find out how important strategic leadership is in Indonesia's commitment to building a blue economy-based marine economy. The approach used in this research is qualitative - descriptive with the researcher as the main research instrument and the design approach used is descriptive-explanative. the findings in this study found that the role of leadership is very crucial in realizing the success of development with a blue economy approach, Indonesia's abundant natural resources will be meaningless if there is no role of leaders who are able to manage and mobilize all their potential. It is important that all parties involved are involved in helping to create a prosperous marine economy based on a blue economy. The demand for marine and fishery resource-based development to be used as a driving force in national economic development.

Tanjung Piai, Malaysia Coastline changes are caused by abrasion and accretion processes triggered by intensive human activities in coastal areas. A coastline change will bring the potential for conflict and security threats to maritime countries, such as Indonesia. Monitoring shoreline changes is essential for studying coastal dynamics, protecting the coastal environment, and developing the coastal environment. This study aims to determine the changes of Tanjung Piai, Malaysia Coastline with Digital Shoreline Analysis System method and the effect on Indonesia's maritime security. The type of data used in this research is secondary data. This study shows that the Coastline changes along the West Coast of Tanjung Piai, Malaysia tend to be significant from year to year. Prediction the coastline that directly faced the Malacca Strait will experience accretion, while it will experience abrasion in the east. The highest accretion on transect 2, namely Sungai Permas Kechil of 19m/year with a distance of 600 meters. It was found that the influence of changes in the coastline of Tanjung Piai, Malaysia, on maritime security was seen from four aspects, namely aspects of sea power, marine safety, blue economy, and human security
