Rubber is a hydrocarbon polymer formed from a milky emulsion (known as latex) obtained from the sap of several types of rubber tree plants but can also be produced synthetically. More than half of the rubber used today is synthetic, but several million tons of natural rubber are still produced annually, and it is still an important material for several industries including automotive equipment, hospital equipment, household appliances, and military equipment. A number of locations in Indonesia have suitable land conditions for rubber cultivation, most of which are in Sumatra and Kalimantan.

The amount of world rubber consumption is increasing and higher than the existing production. That way, Indonesia will have the opportunity to become the world's largest producer because the main competing countries such as Thailand and Malaysia are increasingly lacking in land and it is difficult to get cheap labor so that this can be a comparative and competitive advantage for Indonesia to be better for the improvement of the rubber industry.
