World Ocean Day has been commemorated every June 8 since the first submission in 1992 by Canada at the Earth Summit in Rio de Janeiro, Brazil. This anniversary was then endorsed by the UN at the end of 2008. World Ocean Day is a memorial day to appreciate the world's Oceans by celebrating the results provided by Oceans, such as seafood and marine life for aquariums, pets and it’s time to appreciate the intrinsic value itself. The sea also provides shipping lanes for international trade. In addition to appreciating the World's Oceans, World Ocean Day is also commemorated to raise awareness of the community to preserve the sea. For Indonesia as an archipelagic country that has a vast sea zone and rich in marine biodiversity, World Ocean Day becomes an important moment for the Indonesian nation. World Sea Day commemoration again awakens the Indonesian people about the importance of preserving the sea of Indonesia and inviting the community to participate actively. The Indonesian government has been trying to preserve the environment of Indonesia by making various conservation areas as national parks. Indonesia has many national parks and some of them include marine areas. Let's get to know the marine national parks in Indonesia. Before contributing actively in the effort to conserve the sea, first identify 5 Indonesian Marine National Parks in various regions in Indonesia. The first one is Bunaken National Park. This National Park is located in North Sulawesi. The marine beauty of Bunaken National Park is no longer indisputable, considering becomes the home of more than 300 species of coral reefs and various marine biotas. Because Bunaken National Park is located close to the center of the Coral Triangle, a coral reef triangle that becomes the center of marine biodiversity in the world as well as the top priority of global marine conservation. Second park is Wakatobi National Park. This park which is located in Southeast Sulawesi is a part of conservation of coral reefs and marine life, such as stingrays and whales. Wakatobi itself stands for the name of the four main islands in the area namely Wangi-Wangi, Kaledupa, Tomia, and Binongko. Third one is still on the island of Sulawesi, Togean Islands National Park which is located in Central Sulawesi. The islands and waters of Togean are protected because they have a wealth of coral reefs and amazing marine life. In addition, the Togean Islands become home to the Bajo Tribe; one of the tribes in Indonesia whose life is very close to the sea. Therefore, this national park not only offers the experience of enjoying the beauty of nature but also learning the richness of Indonesian culture. In addition to the island of Sulawesi, Java Island also has a marine national park. It is located not far from the capital of Jakarta that is in Ujung Kulon, Banten. Besides covering the islands and waters with diverse biological riches, Ujung Kulon is also home to endangered rhinoceros, the Javanese Rhino. Krakatau volcano which was famous for its massive eruption in the past is included into the Ujung Kulon National Park. Finally, Komodo National Park is located in East Nusa Tenggara. This area gets the title of the national park because it has stunning sea beauty. This national park has become a favorite tourist destination for both domestic and foreign tourists. One of the attractions of Komodo National Park is the presence of endemic species of Indonesian endangered komodo dragons.
