บทคัดย่อ (EN): This study was aied to develop the Decision Support System (DSS) for sustainable rnanagement and utilization of natural resources. The DSS is used for emphasis in agricultural resources managernent where were damaged by landslide in the area of Maephoon Sub-district, Lablae District, Uttaradit province. The key criteria and constraints used for decision making on the appropriate measures for manageinent and utilization of agricultural resources in farmn scale, namely topography, current land-use, soil fertility status, landslide and mud deposition characteristics, type and size of deposited materials, and plant species used for land rehabilitation. These parameters could indicate how suitable the environmental conditions of individual plot. DSS was designed using Visual Basic 2008 which consists of three major components: (1) agricultural resources database management systemn, (2) functions for assessing land suitability, and (3) functions for determining the appropriate measures for management and utilization of agricultural resources in farm scale. As a result, the created DSS can contribute to help in the decision making process for determnining the appropriate measures for management and utilization of agricultural resources under various environmental situations at fann scale Utilization of low amylose content rice mixing with high anylose content rice, ratio of mixing and rice varieties of using is still a secret for each rice mill and there has been no written data or publications. The objective of this research was to improve the texture after cooking of Chainat | and Phitsanulok2 rice to be similar to that of Khao Dawk Mali105 rice by using low amylose content rice mixed with Chainatl and Phitsanulok2 rice in appropriate ratio in order to improve the texture after cooking. The suitable ratio of low amylose content rice such as Patumthani 1 and RD6 rice to mix with Chainat1 and Phitsanulok2 rice and the ratio of rice to water were determined due to obtaining texture quality after cooking be similar to that of Khao Dawk Mali105 rice. The physical, chemical and physicochenical properties of Khao Dawk Mali105, Chainat 1, Phitsanulok2, Patunthanil and RD6 and mixed rice at different ratio before and after cooking were investigated. Furthermore, marketing test, inventory cost and technology transfer to target group were conducted. Before cooking, all five rice varieties had the length of grain 6.93-7.73 mm, breadth of grain 2.06- 2.24 mn, length-breadth ratio 3.09-3.65. RD6 rice had significantly higher lightness value than that of other rice whereas Khao Dawk Mali105 had significantly lower lightness value than that of other rice (p0.05). RD6 rice had significantly higher alkali spreading value than that of other rice (Ps0.05), following by Phitsanulok2 and Patunthanil whereas Khao Dawk Mali105 and Chainatl rice had significantly lowest (p_0.05). Increasing the ratio of mixing between Patumthanil and RD6 rice to that of Phitsanulok2 and Chainatl rice, the length of grain of mixing rice before cooking was significantly decreased (P?0.05). Increasing the ratio of mixing between Patuntbanil and Phitsanulok2 rice, the lightness value decreased. When mixing Phitsanulok2 and Chainatl rice with RD6 rice, increasing ratio of RD6 rice resulted in significantly increased lightness value of mixed rice (PS0.05). All mixing ratio between Phitsanulok2 and RD6 rice had significantly higher lightness value than that of other mixed rice (p_0.05). Increasing the mixing ratio between Phitsanulok2 and Patumthani l rice reduced the protein content of the mixed rice. All mixing ratio between Chainat1 and Patumthanil rice had no significant differences in protein content (p>0.05). Increasing the ratio of mixing between Patumthani l and RD6 rice with that of Phitsanulok2 and Chainatl rice, the amylose content of mixed rice significantly decreased (P?0.05). Mixing of Phitsanulok2 and Chainat1 rice with Patumthanil rice increased the amylose content of the mixed rice higher than that mixing with RD6 rice (PS0.05). Mixing of four rice varieties at different ratio resulted in no significant differences in the moisture content of the mixed rice (p>0.05). The study of physical and chemical properties after cooking of five rice varieties showed that cooking time of Chainat1 rice (18.00 min) and Phitsanulok2 rice (19.00 min) wwas significantly longer than that of other rice (P0.05). Phitsanulok2 rice had the highest percentage of increasing volume (Ps0.05), following by Chainatl, RD6, Patumthanil and Khao Dawk Mali105, respectively. Percentage of length elongation of five rice varieties was not significantly different (p>0.05). Percentage of breadth elongation of Patumthanil and Chainat1 rice was significantly higher than that of other rice (PS0.05). RD6 bad significantly lowest percentage of breadth elongation (Ps0.05). Percentage of water absorption of Phitsanulok2 rice was significantly higher than that of other rice (Ps0.05), following by Chainatl, Patumthanil, Khao Dawk Mali105 and RD6, respectively. Phitsanulok2 rice had significantly higher lightness value than that of other rice whereas RD6 rice had the significantly lowest (P?0.05). The protein content of Chainat1 and Phitsanulok2 rice was not significant differences (p>0.05) and it was higher than that of RD6, Khao Dawk Mali105 and Patumthani l, respectively. The texture after cooking of five rice varieties revealed that all texture properties of Chainat1 and Phitsanulok2 rice were significantly higher than that of Khao Dawk Mali105, Patumthanil and RD6 (PS0.05). This was mainly due to these two rice varieties had high amylose content. From the results, the most appropriate rice variety and mixing ratio could be selected in order to get the texture after cooking of mixed rice similar to that of Khao Dawk Malil105 rice. These were Phitsanulok2 mixed with Patumthanil rice at the ratio of 6 0:4 O and rice to water ratio of 1 :2.3 and Chainatl mixed with Patumthanil rice at the ratio of 50:50 and rice to water ratio of 1:2.0. Therefore, the selected mixed rice was used for the liking test or acceptance test of 345 consumers compared to Khao Dawk Mali105 rice. All 345 consumers used to consume and liked cooked rice because it was the main course. Three hundred and forty consur umers interested in mixing of 2 rice varieties due to obtaining properties similar to that of Khao Dawk Mali105 rice. The reason for this was the price, following by the nutrition. Five consumers were not interested in mixed rice because they didnt like soft texture rice. The most important characteristic of rice grain that consumers wanted was the nutrition. The package of rice grain that consumers liked was the plastic bag with the appropriate weight of 5 kg and the price of 200-250 Baht. The most important factor that affected the decision n making of purchase was the price, following by the nutrition. The liking scores of all tested sensory attributes of Phitsanulok2 mixed with Patunthanil rice and Chainat I mixed with Patumthanil rice was in the range of Tike slightly - Tike moderately while for that of Khao Dawk Mali105 was in the range of like moderately - like very much. However, the selected mixed rice from this research was well accepted by the consumers. When the inventory cost of mixed rice was compared to that of Khao Dawk Mali105 rice, it was found that Phitsanulok2 mixed with Patumthani l rice at the ratio of 60:40 and Chainatl mixed with Patumthanil rice at the ratio of 50:50 bad the inventory cost of 20-25 Baht/kg which was cheaper than that of Khao Dawk Mali105 rice which had the cost of 33- 37 Baht/kg. The technology transfer was conducted to the target group of 32 people and it was found that all attendees had the happiness scores both format and content of both theory and practical sessions in the level of very good. In conclusion, the texture after cooking of Phitsanulok2 and Chainatl could be improved similary to that of Khao Dawk Mali105 by mixing with Patumthani l rice at an appropriate ratio.
