摘要：The objectives of this study were to investigate and estimate the economic, social and ecological benefits of agricultural waste processing and to assess farmers' perception on agricultural waste processing. This research was conducted in Kecamatan Tanjung Lago, Banyuasin, Sumatera Selatan. Survey data were collected from farmers selected using disproportionate stratified random sampling. The results showed that the economic benefits of agricultural waste processing were reducing production costs, increasing income of rice and maize farming, and improving the welfare of farmers. The social benefits were raising the nature of cooperation and triggering farmers to have broader knowledge by organizing associations to exchange the knowledge. Whereas, the ecological benefits were reducing air pollution caused by combustion of agricultural wastes, improving soil physical properties and restoring nutrients obtained from agricultural waste processing. The value of economic benefits estimated from agricultural waste processing to produce liquid bacterial fertilizer were 29.4% and 29.8% increase in income of rice farmers and maize farmers respectively. The overall score of perception of farmers applying agricultural waste processing was higher than those not applying.
