Abstrak: Accelerated Aging Machine (MPC IPB 77-1 MM) is a tool that can accelerate the deterioration of seed by using 96% ethanol vapor. Utilization of these machines are intended to be seen accelerated aging of seeds and comparing it with the natural deterioration during storage. This research aims to determine the suitability of loss of viability, vigor and increased electrical conductivity of soybean seeds that have accelerated aging using ethanol vapor compare to natural storage and estimate the vigor storability. The research consisted of two experiments is a natural storage and accelerated aging. Natural storage consists of 7 storage periods are 0, 1, 2, 3, 4, 5, 6 months and accelerated aging also consists of 7 periods are 0, 1x15, 2x15, 3x15, 4x15, 5x15 and 6x15 minutes. Results showed that the rate of decline suitability viability, vigor and an increase in electrical conductivity between natural storage with accelerated aging using ethanol vapor. MPC IPB 77-1 MM can estimate vigor storability of soybean seed on the benchmarks Germination (DB), Vigor Index (IV) and Speed Growth (KCT). KCT benchmarks more sensitive in predicting vigor storability, but a measure electrical conductivity is not sensitive in predicting vigor storability. Tanggamus and Wilis varieties have high vigor storability, while the varieties Kaba and Sinabung have lower vigor storability.

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.

Abstrak: Reticulated python is a non-venomous snake native to South and Southeast Asia. It is the world's longest snake. The purpose of this literature review study is to investigate the common bacterial flora found in oral cavity of the reticulated python. The data for this case study was obtained from several articles, journals, books and credible websites. Based on existing data, there are a wide variety of bacteria in the oral cavity of free-living reticulated pythons. The majority of the organisms were Gram-negative. Pseudomonas spp. were the most commonly isolated bacterial species, being found in 50% of the snakes sampled, and was followed by Staphylococcus sciuri.
