Judul: Pemanfaatan alat pengusangan cepat (APC) IPB 77-1 MM untuk pendugaan vigor daya simpan benih kedelai (Glycine Max (L.) Merr.)
Abstrak: The research was conducted at the Laboratory of Seed Science and Technology, Department of Agronomy and Horticulture, Faculty of Agriculture, Bogor Agricultural Institute from April to May 2012. The objective of the research was to test the utilization of Rapid Aging Tools (APC) IPB 77-1 MM to estimate the shelf life vigor of soybean (Glycine max (L.) Merr.) seed and to obtain the procedures for using APC IPB 77-1 MM. This research used physical accelerated aging and chemical accelerated aging on soybean seed of different vigor levels by using APC IPB 77-1 MM. The working principle of this tool is aging seed with a scourging heat vapor for physical accelerated aging and the steam of 95% ethanol for chemical accelerated aging during a given period. The results showed that APC IPB 77-1 MM can be used to estimate the shelf life of soybean seed vigor with physical accelerated aging and chemical accelerated aging. However, a method of physical accelerated aging more consistent than with chemical accelerated aging. Physical accelerated aging conducted using a scourging heat vapor for 0, 1×15, 2×15, 3×15 dan 4×15 minutes on temperature and RH of 52°C and 89%, and chemical accelerated aging conducted using the steam of 95% ethanol for 0, 1×20, 2×20, 3×20 dan 4×20 minutes on temperature and RH of 32°C and 82%. In terms of technical, procedure of chemical accelerated aging easier to do than with physical accelerated aging.

Judul: The use of accelerated aging machine IPB 77-1 MM for varieties screening of soybean (Glycine max L.) based on seed vigor related to storability
Abstrak: Accelerated Aging Machine IPB 77-1 MM could be used for varieties screening of soybean (Glycine max L.) based on seed vigor related to storability with physical or chemical accelerated aging test. The aim of the research were to find out a simple, fast and accurate accelerated aging method by accelerated aging machine IPB 77-1 MM which is suitable for varieties screening of soybean based on seed vigor related to storability. Two methods of accelerated aging test (physical and chemical treatment) by accelerated aging machine IPB 77-1 MM, were applied to Anjasmoro soybean seeds varieties. The best accelerated aging method then was used to 23 soybean seeds varieties screening based on seed vigor related to storability. The seed vigor related to storability of 23 soybean seeds varieties which is detected by accelerated aging machine MPC IPB 77-1 MM were compared with seed vigor related to storability of 23 soybean seeds varieties which is stored 10 weeks in natural storage system.Result of the experiment showed that chemical and physical treatment of accelerated aging method in accelerated aging machine IPB 77-1 MM could decreased seed vigor, but the chemical treatment could decreased seed vigor more fast and chemical treatment was more practical and simple. Accelerated aging machine IPB 77-1 MM could be used for varieties screening of soybean based on seed vigor related to storability by using electrical conductivity test.
