Indonesia began to grow natural rubber in 1902, and is now the largest country in the world to grow natural rubber. The total cultivated area in 2006 is 3.309 million hectares.
Indonesia natural rubber planting area is the first in the world, but it has the world's largest production, mainly because of low productivity of natural rubber in Indonesia, because of the natural rubber prices fall, small plastic glue park owner was forced to leave, the other for a living, the small plastic garden neglected, even facing abandoned, but in recent years, due to the natural rubber price rises year by year, farmers produce glue enthusiasm is greatly increased, back to the garden is committed to the production of rubber, rubber so production is growing rapidly, despite Indonesia yield per unit of output is lower, But the average annual growth rate of natural rubber production increased from 2.8% in 1991-2000 to 8.7% in 2000-2006, and even to 11.6% in 2006. Indonesia's share of world rubber production increased from 22.1 per cent in 2001 to 27.8 per cent in 2006
Indonesian rubber analysing mainly SIR20, produces 80% of the total output, most of the small park owner use cup adhesive clot SIR20 as production raw material, the clot is made from natural latex coagulation, often containing impurities, and contains a lot of water, when storage is not easy to weightlessness, so farmers mainly on clot weight estimated net sales glue content, general clot net glue content is 55%.
The traditional processing technology is still adopted in Indonesia. SIR processing is different from other countries. The main difference is that the raw materials must undergo a natural air-drying process for 10-14 days.
