Pengaruh Beberapa Kemasan Plastik terhadap Kualitas Benih Kedelai Selama Penyimpanan

Soybean seed var. Argomulyo has been processed and dried to < 10% moisture content. Seeds were stored in 3 different kinds of plastic packaging ie. HDPE, hermetic plastic and vacuum plastic for a period of 6 months at room temperature. The research aims to determine the best type of plastic packaging for soybean seed. The experimental design was arranged in RBD consisting of 2 block and 1 factor; different engine rotation n speed (rpm) threshing and packaging material. Sample was carried out every month until 6 months of storage. The following analyses were carried out: moisture content, germination, damaged grains, additional weight and free fatty acid (FFA). Result show that kinds of packaging significantly affect moisture content and additional weights. It was found that seed moisture contentin HDPE packaging was increase and showed positive correlation with additional weight. Engine rotation speed (rpm) threshing was significantly affect damaged grains that high rpm showed positively corelation with increasing damaged grain. Percent of FFA < 0.4% untill 6 months of storage. From this research, soybean seed was stored in hermetic plastic observed have the ability to maintain moisture content and hold up additional weight followed by vacuum plastic and HDPE. Soybean seed were stored in HDPE, hermetic plastic and vacuum plastic have percent of germination ≥70% after 6 months stored and moisture content < 10%
