There is a wisdom behind the disaster, maybe this is the right sentence that describes what was done by the student of Semarang Diponegoro University (UNDIP). Recently their work was awarded a gold medal in the International Trade Fair of Ideas Invention and New Product contest in Germany in November 2018.
Considering that Indonesia is in the ring of fire area which has resulted in a lot of geological activity that has the potential for earthquakes, the students consisting of Yunnia Rahmandanni, Latifa Nida, Nurul Hidayah (Faculty of Science and Mathematics), Ibadurrahman (Faculty of Engineering), and Rifqi Rudwi (Faculty of Fisheries and Sciences Marine) created a work on Innovation in anti-earthquake roof tiles which are claimed to be suitable for use in earthquake-prone areas
Anti-earthquake roof tiles are made from materials that are often found around the house. Roof tiles are made of sand, cement, water and styrofoam waste. Because given an additional Styrofoam, this tile is different from the general tile, because it weighs lighter. With that lightness, this tile is claimed to be suitable for use in earthquake-prone areas. When an earthquake occurs, it is expected to minimize casualties.
The Chair of the Styrofoam Roof Tile Team, Yunnia Rahmadani, explained that the tile was made specifically in the area where she lived, in Grobogan Regency. She claimed to need several attempts to make the tiles made according to specifications.
She also explained that the anti-earthquake tile could be called environmentally friendly because it was able to recycle styrofoam waste. Some of the waste material is also taken from the Final Disposal Site (TPA) in UNDIP.
The waste taken is then mashed, mixed with sand and cement mixture, then put into the mold. Based on laboratory data, the strength of the anti-earthquake tile is on average strong, with a weight per tile reaching 760 grams. “This tile is environmentally friendly. We use the Styrofoam waste from the many UNDIP landfills.
Styrofoam was chosen because the waste is difficult to decompose, “said the 7th semester student. Together with her team, Yunnia then tried to include the work in the competition in Germany. The ideas compete with 800 researchers from other countries, of which two of them are from Indonesia. The supervisor of Styrofoam Tile, M Nur Sholeh said, the difference between tile and other tiles is the addition of addictive substances in the form of waste. Styrofoam waste taken from TPA is then mashed, mixed with the mixture.
This work is very in accordance with the geography in Indonesia, hopefully with the right socialization and government contribution, this work can be patented as an authentic Indonesian product and can inspire other young generation to continue working to make things constructive and beneficial for the country and nation.
