The knowledge of the distribution pattern of a commodity is an important factor in determining ways and means of reducing processing and handling losses as well as in maintaining good grain quality. A study on rough rice and maize had been conducted at Kabupaten Kediri, East Java [Indonesia], where the flow of the commodity was traced from harvest to farmers' village cooperatives (KUD), private millers and Logistic Depot (DOLOG). As an approach to the problem, a mass balance model for both commodities at each node of the flow network was developed. Data collection was designed to cover the peak harvests for the wet and dry seasons of 1986 and 1987. Through mathematical analysis, the occurrence of post-harvest losses from the farm to DOLOG's storage was determined. There was a strong indication that under the present handling system, rough rice and maize are still retained cumulatively in significant amount at farm level. It is recommended that KUD operation in the region be increased to reduce further the amount of post-harvest losses and to maintain good and consistent product quality.
