Mukim Rambai

Mukim Rambai is a mukim in Tutong District, Brunei. The population was 1,404 in 2016.

Name
It is said that there is an area where traders stop and gather to buy and sell goods in exchange for goods such as salt, copper goods with forest products, agriculture and the like from people in the interior. This settlement is one of the stopping places called 'empat betamu for business before heading to other villages along this river including villages close to tributaries whose mouths flow into the Tutong River. In the area where the betamu is held, there is a fruit tree called Pohon rambai which since the beginning has grown in the depths near the bank of the river.

The tree had sunk in a sitting position, that is, the whole tree went into the river. Some say that the tree appears on the surface of the water when the moon is full. When this tree emerges from the surface of the water, the tree is filled with flowers and according to the story there is a fish called ikan dalak (haruan) the size of a bushel, which has scales in the form of beads around it between his head and body playing while swimming around the tree. With the story of Pokok Rambai, the local residents at that time named this village in conjunction with the name of the tree, which is Kampong Rambai. The scene of the incident has been eroded due to the river's headland breaking off and being eroded by river water and climate change from time to time.

Geography

The distance is approximately 36 kilometers from Pekan Tutong to the headwaters of this river. In the past, before there was progress in the interior of this area, the river was a very important link. The river is not only a source of daily needs, agriculture, fishery, but it is also the main link for boat transport between traders and people who live along the Tutong River.
