The research objectives were: (1) to determine which ruminants could be developed based on regional resource support; and (2) to identify the potential of agricultural waste to support livestock development in Pidie Regency, Aceh. This research used descriptive and exploratory methods. The descriptive method described the condition of development of potential forage areas in the Pidie district. The population data for large ruminants was calculated based on the population structure of production (weaning, young, adult, and imported cattle). Furthermore, the population based on age was converted into Animal Unit (AU). The results found that the Pidie regency had the potential for livestock development. The sub-districts of Padang Tiji had an ample opportunity as producer of rice farming waste with a total of 4,734.80 tonnes/year, maize 81.3; cassava 12.5; soybean 4.95; green beans 1.37 and peanuts 0.822 DDM tonnes/year. The potential that had not been utilized was 4,241.57 tonnes/year and has a capacity of 3,720.68 (ST/year), followed by Sakti district and Mutiara Timur districts. The conclusion showed Pidie Regency can increase the population of ruminants by increasing the benefits of feed from agricultural waste.
