Sensory evaluation with descriptive method on Aceh local rice (Oryza sativa L.) mutant M6 using Gamma-ray irradiation

Abstract

Aceh is the richest province in Indonesia in the context of diversity with the local rice varieties. Therefore, it requires conservation efforts within this issue. The weakness parameters of local rice are long-lived and low production. One of the technologies that are been used to obtain the characteristics of short-lived local rice and high production is by using gamma-ray irradiation technology. This research aims to know the quality of sensory evaluation with descriptive method on Aceh local rice Mutant M6 by gamma-ray irradiation. The Aceh local rice Mutant M6 that has been used in this study were I-CKU-6, UF1 B4-9-2017, O-SGP, O-10D, S-103, S-97, S-01 (conventional and organic cultivation), O-39 e, O-10 d, O-57 e (organic cultivation), S-97, S-84 dan UFi-B (conventional cultivation). The approach that has been used in this research was using Completely Randomized Design (CRD) non factorial with three replicates. The result showed that local rice with irradiated gamma-ray (M6) had a very significant effect on the flavour, color, texture, shape, and overall acceptance of rice by conventional and organic cultivation. The local rice O-SGP (5.82) is the local rice that has been received by panelists, followed by local rice S-103 (5.75), O-10D (4.95) and S-97 (4.70), while the aroma was favored by panelists is O-SGP (4.92). The S-84 local rice which was grown conventionally was preferred by panelists with a value of 9.85.
