Halmahera Island is the largest island in the Maluku archipelago which is located in North Maluku Province. Divided into six districts with a total land area of ​​17,780 km2. This land stretches to form a large peninsula, most of which is covered with natural forest. The highest peak is at an altitude of 1,560 meters above sea level. Forest cover is dominated by secondary and primary forests, stretching to form clusters of hills and lowlands. There is one conservation area on Halmahera Island, namely the Aketajawe Lolobata National Park which is divided into two forest block areas, namely the Aketajawe and Lolobata forest blocks.

Many people on this island live in coastal areas. There are various tribes living, including Tobelo, Ternate, Tidore, Makian, Bugis, Buton, Sangihe, Minahasa, Sundanese and Javanese. Potential natural resources used as the main source of livelihood by village communities are coconut, nutmeg, cloves and wood. In the industrial sector, the largest potential minerals are nickel and gold.

Halmahera Island is home to 252 species of birds, 26 of which are endemic to North Maluku, and four of which can only be found on Halmahera Island, namely the mandar gendang, the droopy kingfisher, the Halmahera kepudang, and the Halmahera sungut.

Because it has a very unique biodiversity, a famous explorer named Alfred Rusell Wallace in the 19th century visited Halmahera and its satellite islands and got the greatest inspiration about adaptation and the origins of species diversity which became the forerunner to the theory of the evolution of living things.
