Abstract
Use of Side Products of Rice Mills in Support of Agroindustry. Sri Widowati. Rice is the
most important food crop in Indonesia. Rice production, processing, and distribution activities need more labours and may become sources of income to the farmers. The country's rice production rate is relatively low, i.e. 50% of the population growth rate. Therefore, rice production need to be imporved by increasing of the crop productivity, breeding through conventional and modern technologies (biotechnology), extensification, as well as post harvest handling and processing of side product from rice mills. Type of rice grain polish affected the physical quality of rice. Type of grain friction resulted in lower rice brewers (2%), glossy, but low whiteness (41%). Type of grain abrassiveness type resulted in higher rice brewers (5%), but seem to be more whiteness (55%). Polishing rate enfluenced the yield recovery of the side product, especially for rice bran; the higher polishing rate, the higher office bran recovery. Side
product from rice mills are rice husk (15-20%), rice bran (8-12%), and rice brewer (5%). The annual rice production of the country is approximately 49.8 million ton. This means that about 7.5-10 million ton of rice husk, 4-6 million ton of rice bran, and 2.5 million ton of rice brewer were produced annually. The use of side product from rice mills were still limited. Rice brewer is commonly used material for traditional food product, flour, and high protein rice flour. Rice husk is used for planting media, fuel, component in brick making. Coarse bran was used as animal feed, while the fine bran was used in making traditional food and extrusion product. High nutrient content of stabilized rice bran can be used as raw material in food and non-food industries.
