Five students of Faculty of Agriculture Technology of Brawijaya University created tool of Batik industry textile waste processor used “Platinum Inert Electrolysis Technology and Activated Carbon”. They are Juli Erwanda (TBP 2013), M.Dody Darmawan (TBP 2013), Agus Setiawan (TEP 2012), Natalia Simanjuntak (TBP 2013), Rahma Wati Pertiwi (TBP 2013), under supervising Shinta Rosalia Dewi, S.Si., M.Sc.
“Our first idea is batik is gift for Indonesia people and it admitted in world. But, from many craftsmen in the world, there is no batik waste process that really effective and efficient. This will causes in the emergence of harmful wastes and the adverse impact on the surrounding environment. Surveys have proved there are about 50.000 Indonesian batik craftsmen spread. Currently in Malang city itself there are about 230 craftsmen. Our current partners are Rudi Arianto Bhre Tumapel batik industry owners in the village Bandungrejo Sari sub district Breadfruit Malang. To produce three pieces of batik cloth from beginning to end takes more than fifty liters of clean water every week. So if calculated for one month would require more than 200 liters of clean water. Yet it was only in the batik industry in the city of Malang. Well what if we calculate entire batik industry in Malang? Indonesia? “ Juli Erwanda said as team leader.
Doddy, other team members added, “Our equipment uses platinum as inert electrode to reduce the heavy metals contained in the waste of batik. The use of platinum in the electrolysis process is considered very good because platinum is one metal that is difficult to react with water, air and other chemicals, so that platinum is resistant to corrosion. After the electrolysis process, the wastewater flows into a pipe that contains activated carbon. Activated carbon serves as adsorbent in purifying water electrolysis process results.” He explained.
“We hope that in addition to qualifying National Science Week, our waste treatment plant can be accepted by society. Our future goals is to create a useful tool for all aspects, whether human, environmental, as well as the world. With the implementation of this tool then these three aspects can be realized, “he concluded. (dse/Translated by Ratri)
