Judul: Pemanfaatan Mesin Pengusangan Cepat (MPC IPB 77-1 MM) Menggunakan Etanol untuk Pendugaan Vigor Daya Simpan Benih Kedelai (Glycine max L. Merr.).
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.

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.

Judul: Bakteri Flora Paling Umum Ditemukan Di Rongga Mulut Python Retikulatus Liar
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.
