DwiNailul Izzah and Rintya Aprianti Miki are two students who won the
gold medal at the Indonesian Science Project Olympiad (ISPO), which
is held every year at the end of February in Jakarta, with their
original invention and respectful of environment.
The
two young inventors have create an affordable air freshener made from
cow dung. Yes dung, as weird as it sounds, the formulation actually
has a pleasant herbal smell. This two girls overcame 1,000 other
competitors with their surprising freshener, which was created by
collecting unused cow manure from a cattle farm in Lamongam, East
Java, and fermenting it for 3 days: "Then they extracted the
water from the fermented manure and mixed it with coconut water.
Finally, they distilled the liquid to eliminate all impurities. The
whole process took 7 days, which is pretty long, but in the end they
obtained what they were looking for – a liquid air freshener with
an herbal aroma from digested cow food."
Their
natural deodorant is healthier, contains no chemicals that are found
in similar products available on the market, and is also cheaper.
While a traditional deodorant to 275 grams costs 39,000 Indonesian
rupiahs (about $ 4), a 225-gram cans of deodorant from cow dung only
costs 21,000 rupees (about $ 2), which is half. Explains Dwi Nailul
Izzah: "Our air freshener is not supplemented with chemicals to
smell fragrant, it’s pure and smells like the natural plants fed to
cows."
Dwi
and Rintya are ready to show their cow poop air freshener at the
International Environment Project Olympiad (INEPO) held in Istanbul,
Turkey during May, and are going to file for a patent.
