Zulkifli Nasution, MSc, PhD (Chair), Kasyful Mahalli, SE, MSi (Member), and Drs. HB. Tarmizi, SU (Member). Rubber is one of the plantation commodities in Indonesia. This commodity has been known and cultured for a relatively longer than the other plantation commodities. In the early period of rubber culturing, Indonesia used to be the first rubber producing country in the world before being replaced by Malaysia which began to culture rubber some time after Indonesia did. The Province of Sumatera Utara is known as one of the natural rubber exporters which exports the rubber produced in various districts. Mandailing Natal District is one of the rubber producing districts whose latex production kept increasing from 2004 to 2008. The purposes of this study were to examine the influence of work capital, man power, and land area on rubber production and to analyze the role of rubber as a commodity in the regional economic development of Mandailing Natal District.
