This research report is manipulated that summarized the moment of research project in the subject of “The optimal image processing for paddy studies: Variety classification and rice kernel damage inspection”. This project had been take time in 12 mounts. We focused on rice variety classification and rice kernel damage inspection. We also investigated the apparent friction of rice surface. Results showed that area and size were the quantities that have the potential to classify rice variety and also rice kernel damage inspection. In addition we also found that geometric mean diameter performed characteristic to apparent friction of rice surface in kerosene. These results have the potential to be the basis information in terms of developing instrument for quality control and variety classification of cereal.

FAO reported in year 2008 world paddy production more than 40 countries and about 60 million tones of rice straw were produced in Thailand. For most farmers use an easy method for land clearing by straw burning in open area. Greenhouse gases such as carbon dioxide(CO2) emissions from paddy field burning to atmosphere is causes of global warming problem. This project aimed to utilize agricultural waste from rice field to be cheap biomass energy was started in 2009 at Nhongjork area. The waste was mixed with molasses and kaolin in ratio of rice straw : molasses : kaolin as 80:10:10 by weights. A size of rice straw fuel pellet was 1.54 cm. diameter and 2 cm. height. The calorific value of the rice straw pellet was tested by using Gallekamp Autobomb instrument by ASTM(American Society of Testing and Materials) standard. The results of testing found : CO2 emission from rice straw fuel pellets as half of burning in open area (by weight). Cost of energy for cooking by using Bio-fuel pellets only 7 Baht( 0.25 US $) and half price by comparing with LPG. The useful of rice straw Bio-fuel pellet is one of a cheap biomass energy for household and small manufacturers.
