Universitas Brawijaya students Create a Lifetime lamp Monday, 18 MEI 2015 | 5:10 pm Malang, Faculty of Fisheries and Marine Science Universitas Brawijaya transform bacteria into energy-saving lamps.
With Elok ,Fitriany Tauziat, Nurhasna Fauziyyah, and Alfie M. Arifin hands, bacteria Bioluminescene processed into biolie lamp which produces light 10.68 watts. This lamp is able to light up a room within a radius of 68 meters.
"Energy-saving lamps can overcome the problems of the energy crisis," said Elok, Sunday, May 17, 2015. Along with population growth, the growing energy needs. While the energy supply dwindling fossil-based energy.
Bacterial Bioluminescence is a bacteria that is stuck in the body of the squid. The bacteria are able to emit blue light. The lights grew brighter if the number of bacteria content plus. "The light that is generated does not generate heat," he said.
The lamp has a variety of advantages, namely the environmentally friendly and economical because it can be worn for life. Because of dead bacteria will produce new sires. Easy lamp against the wall or placed on a table.
How to make it, the bacteria from the body of the squid isolated in a biolie with a concentration of 4,6x109 CFU per milliliter. Biolie is a device consisting of a lens mica, compressed sawdust, and aerator.
"To be able to continue to shine this light, the bacteria nourished," she said. Nutrients in the form of organic material from fermented vegetables. The trick, finely chopped vegetables poured soy sauce, sugar, and EM4 then dried.

In developing countries, patient safety is threatened because the inconsistent supply of electricity when the medical operation. Seeing this, Louise Jaiyeola Oduyoye, a student of a university in the UK, creating Neva. Products made by 21-year-old girl can last up to 60 charging cycles thereby increasing patient safety and optimize the operation process. The medical team involved in the operation can focus on their duties without worrying about the power off when needed.
