Farmers grow a large number of crops. Major industries are gas refining and manufacturing of steel, aluminum, cement, fertilizers, paper, textiles, and cigarettes. They also make cars, trucks, and airplanes. They produce farm products, wood products, soap, and other goods. Indonesian fisherman catch anchovies, mackerel, sardines, scad, tuna, and other fish from the waters.
Fish are a major part of coastal people's diet.
Forestry in Indonesia includes bamboo, mangrove bark, which is used for dyes, and cinchona bark, which is used for medicine in Indonesia. The transportation is small because of the mountains and forests. Small vehicles called ''Bemos'' pick up and let off passengers along Indonesian roads. Railroads operate on the islands of Java, Mandura, and Sumatra. Vessels carry passengers and freight along coastal islands.
