The main commodity export of Malaysia is still oil palm which is known as the backbone of Malaysian agriculture. Various problems and techniques on managing oil palm plantation has been introduces by many researchers and found that monitoring the status of oil palm plantation through online facility is very important. This could be achieved by using game engine technology. This paper discussed the conceptual idea of developing an online 3D oil palm management system based on game engine technology. The game engine can be utilized to simulate the management of an oil palm plantation, as using 3D will allow a lot more information to be conveyed. Game engines allow so much customization as able to construct an online 3D oil palm plantation. This idea would be beneficial to everyone especially future developers who might expand this idea.
