Kakaban Island

Archipelago Uniqueness River delta east of Berau, East Kalimantan named Derawan Islands. This archipelago consists of six main islands, namely Pulau Maratua, Derawan Island, Charitable Island, Long Island, and Samama Island Kakaban. The islands are also carrying an hatcheries green turtle (Chelonia mydas), the largest in Southeast Asia, thus making the locations are known internationally.

Archipelago Uniqueness River delta east of Berau, East Kalimantan named Derawan Islands. This archipelago consists of six main islands, namely Pulau Maratua, Derawan Island, Charitable Island, Long Island, and Samama Island Kakaban. The islands are also carrying an hatcheries green turtle (Chelonia mydas), the largest in Southeast Asia, thus making the locations are known internationally.

Among Derawan Islands, there are also two atoll islands, namely Pulau Kakaban and Maratua. Kakaban an atoll is unique, because it has a lake of this type of jellyfish Mastigia papua, as contained in the Palau Islands in Micronesia, about 750 km in the southeastern part of the Philippines.

Kakaban is ring-shaped atoll with a lagoon tertutup.Laguna intact is a brackish water lake separated from the sea and surrounding Kakaban, makes this island so unique. The water in the lake were still affected tides, but water is not mixed seasin sea water because the rain water (Tomascik & Mah, 1994).

Atoll Kakaban as high as 40-60m above sea level is expected to be formed during 1-2 million years, through the process of elevation of oceanic plate from a depth of about 200-300 meters (Kuenen, 1933) Over millions of years, the lagoon closed-named Lake Kakaban with characteristics are unique, encouraging the process of evolution and adaptation of the biota that live in it, thus forming a community of biota of the lake anchaline unique and endemic.

Most of the biota of the lake kakaban such as the types of jellyfish, Anemone marine predator jellyfish, marine algae, molluscs, sponges, sea stars, sea cucumbers, too type of crab was discovered Orcovita saltatrix (Ng & Tomascik, 1994), a type of -endemic species are newly discovered or described, or a kind rarely found elsewhere.

The results of biological diversity of Lake Kakaban by researchers LIPI joint team from Leiden, Netherlands in October 2003, shows in addition to the four types of jellyfish, there are also 29 species of algae, 43 species of sponges, and three types of tunikata. (Still a lot of these types This as yet unidentified).

In addition to the unique lake, Kakaban still have traction lain.Di biodiversity around lakes, vegetation switch to the roots of mangrove trees with a unique and a place to live for the sponge and the type tunikata around the lake. Forest
jungle with tall trees growing on the coral atoll meeting this island, making it appear similar in mainland forests of Borneo. Outer side Kakaban is high and steep cliff straight into the sea, with its coral reefs are very beautiful, bergua-caves and alleys, are a paradise for divers.

Therefore, the Islands Kakaban Derawan and his unique, felt very proper to be appointed at the international level, by proposing a World Heritage Site
