Padjadjaran University student researching the fungus to break down Styrofoam
Student
majoring in Biology class of 2009 , University of Padjadjaran , Mutiara
Pramoedya Ningtyas , researching fungi that can break down styrofoam
waste . The
study, presented in the International Conference of Live Science and
Biological Engineering at Osaka , Japan , last month attracted the
attention of scientists .
Pearl mushroom research pioneered two years ago . Started when he saw a used plastic box white cake covered with mushrooms like cotton . He suspects there are microbes that can grow on plastic . Most mold is then taken to be grown on agar and further examined .
"
There are eight types of microbial fungi , " Pearl said in the hall
campus of the University of Padjadjaran in Bandung , Monday, December
23, 2013 . He then sort it by jenisnya.Pada microbial research project was initially to race , wearing pearls to styrofoam mold parsed . The reason , it took a century styrofoam to be destroyed in nature . Research to accelerate the destruction of the waste in the ground . ( Read also : Surviving Mercury Waste 10 Thousand Years )
From
the results of experiments with submerged fermentation method , there
is one type of microbes that can break down styrofoam pieces measuring 3
x 3 cm thickness of approximately 2 millimeters . "
Analysis of microbial DNA that is being done , we do not know whether
it's new or old type , " said Astri Wulandari Peni , Pearls research
supervisor .
Lecturer innovation Universitas Sebelas Maret: Environmentally Friendly Foam
At first glance the yellow foam pieces were not different from the commonly used foam society . New differences appear when the surface is touched . The foam feels rough and rather stiff .
"If
the foam on the market or synthetic foam manufacturing process
petroleum wear , we use corn and oil palm waste , " said research team
leader Polymers and Composites Department of Mathematics and Natural
Sciences Faculty of Teacher Training and Education University March
Surakarta , Mohammad Masykuri , on campus , Thursday, October 3, 2013 .Corn
waste foam is environmentally friendly because it can decompose by
itself within 300 days after being dumped or buried in the ground . As with the synthetic foam that can not be destroyed despite decades . " Waste of synthetic foam can damage soil structure , " said Masykuri .
Environmentally friendly foams are named BioFoam PUU - gz or BioFoam Poly ( urethane - urea ) - g- Zein . Research environmentally friendly foam started two years ago . Since the beginning Masykuri wear corn waste because it has the character of a natural polymer . "The skin of the banana and crab shells can also be used , " he said .
Innovation senior high school students 10 Malang: Multifunctional Reactor
Two
high school students Negeri 10 Malang successfully won the special
award and a bronze medal in the International Environment Project
Olympiad High School in Oswego , New York , United States . This
award is given to Edwin Lutfi Saputra and Steavanny for inventing the
multifunctional reactor Interconnected named B Reactor ." Just us and the Hong Kong award -winning special , " said Edwin on Tempo , Monday, July 8, 2013 . They compete with 325 participants from 58 countries . Used batteries converted into mineral crystals useful for fertilizer , animal feed supplements and water purification . The
equipment is designed for five months caught the attention of the jury ,
because the whole process without the use of fossil fuels .
They
create an airtight reactor made of plastic tube about 20 centimeters
in diameter , pumps , manometers , four glass tubes , and plastic cups .
This equipment spending budget of Rp 200 thousand . " Tool is all around us , easy , and inexpensive , " said Edwin .
The
working process of the device is a component of zinc sulfate batteries
are inserted in the tube to react with acids to produce hydrogen
crystals and minerals . Each 120 milliliters of acid produces enough hydrogen to process for 10 minutes . The hydrogen produced is used for heating in the form of an advanced process that produces crystals of the glass tube .
" So the fuel produced by the reactor system , " said Steavanny . The resulting mineral crystals have been tested for fertilizer plants . The result , faster plant growth . This tool is also developed for the purification of water . Bound and dirt settle to the bottom surface of the water . In
addition , functions as a forage supplement also showed results ,
manure has a low content of methane gas , so it does not damage the
ozone layer .
Information Technology Student ITB 2010 make intelligent monitoring application jammed . Applications called Smart Traffic Controller it presents a real time conditions of congestion on the road , such as Jakarta , Bandung , and Surabaya .
The application of artificial Rizal Islamic Flag and Okharyadi Saputra . They rely on the system Global Positioning System ( GPS ) on a smart phone application users . From GPS , the observed position of the rider and the road which traversed .
Indication of the presence of obstacles in the road or congestion , based on the decrease in vehicle speed . " For example, when running smoothly 40 km / h , then dropped to 10 km / hour or until the highway was silent as usual , we can avoid that path , " said Rizal . The application is reserved for motorists with four or more wheels .
Such data from over one user , then processed server . The results serve as a warning barriers or bottlenecks . On screen phone or tablet , jam it in the form of a round green dot on the map .
The more users who experience such conditions , traffic jams, and more accurate information . On the condition of vehicles lined up for a red light , the server ignores the data. The vehicles were parked too silent because not count .
On the map of Jakarta , for example , there were five Tempo round green dots flashing on a laptop screen smart cell phone also . While in London at the same time , there are eleven similar point is lit . Monitoring the traffic on Thursday, November 28, 2013 , at 11:38 pm .
In Jakarta , the green dot lights up , among others, on a map of the Jakarta-Merak toll road , Jalan Sultan Iskandar Muda near the junction with Jalan Purification , and in Palmerah . While in London , the distribution of the congestion point at the same time observed in Dago area , such as Cisitu Road , Sangkuriang , Dayang Sumbi , and Tubagus Ismail .
Smart Stove: Water power
Fire resulting from the combustion process is not colored red water cooker and blue, but the color is white. The fire did not cause scars burnt in wok cooking place. Therefore, the fuel source of water. Siti and other water cooker student inventors hope the findings could be used wider community. "Stove expected to address the water supply of fuel oil continues to decrease," said Siti.
