Abstract

The purpose of this study is to examine the physical quality of grain and milling quality of the local varieties of Yogyakarta rice (Mentikgrompol) and several new superior varieties (Sembada Merah, Sembada Hitam and Inpari 43). The results showed that the percentage of empty grains of Mentikgrompol and Inpari 43 fulfilled the requirements of Indonesian National Standard (INS) of grain in 1993 in the first quality class. While the percentage of green / chalky grains of Mentikgrompol and Inpari 43 met the second quality class. Grain density and weight of 1000 grains of four rice samples ranged from 449.0 g/l (Sembada Hitam) to 531.5 g / l (Mentikgrompol) and 20.09 (Inpari 43) to 24.67 (Mentikgrompol) respectively. Based on the rice form, Mentikgrompol included as bold rice (1,1-2,0), Sembada Merah and Sembada Hitam included as medium rice (2,1-3,0), and Inpari 43 included as slender rice (> 3.0). The yield of broken rice ranged from 69.24% (Sembada Hitam) to 77.56% (Inpari 43) and the yield of milled rice ranged from 62.08% (Mentikgrompol) to 67.81% (Inpari 43). Inpari 43 has the best head rice percentage (94.04%) and almost fulfilled the premium quality class of INS of rice in 2015.
