Kumai is a port in Central Kalimantan province in Indonesia, on the island of Borneo. It lies on the Kumai River.
It was from here that the M/V Senopati Nusantara set out on its ill-fated voyage in December 2006.
Administratively, Kumai is a kecamatan (district) of West Kotawaringin Regency.
Kumai was once part of the Kutaringin Monarchy. It was originally led by Pangeran Bendahara, who later gave Kumai to Muhammad Cik, Kumai's village leader. Cik then gave his position to Amsar, who was chosen to be regent of Kumai.
Kumai was a base for Indonesian fighters attacking the Dutch and Japanese on January 14, 1946. Many soldiers died at the base, but it was maintained. To commemorate the battle, the government built a monument and the Taman Bahagia Park in Sei. On Tendang, and on every January 14, people celebrate in the park to remember Kumai's soldiers. The Kobar regent always attends.
Later, the regent H. Abdul Razak signed a region regulation regarding district forming in a plenary council meeting. Seven factions of council supporters agreed and accepted the Raperda that divided the Kumai District into the specified regions: Pangkalan Lada, Pangkalan Banteng, and Kumai as the main district. Razak later explained, "By forming two new districts, we expect that it can support the public service in governance affairs, development issue and social affairs."
The motto of Kumai is "Beriman," which is an acronym of Bersih (clean), Indah (beautiful), Ramah (sociable) and Aman (peaceful). The motto itself is generally translated as "Religious".
Roads throughout the district vary from dirt to asphalt, but remain adequate. Residents often rent a car or "mikrolet" to travel between towns.
Much transportation takes place on the river. The dock at Panglima Oetar port is the hub for inter-island sea transportation, and is where imports and exports enter and leave the district. Other ports include the CPO and Ferry ports in Sei. Tempenik. Goods and people are also transported on various rivers throughout the district.
Electricity services are dispersed throughout the region, and while many residents drink water from rivers and wells, there is also a drinking water distribution company: PDAM.
