Klojen, MC – At the National Science Olympiad, the innovation of young people in Malang City once again showed its quality. The Leachate Treatment Study, which previously succeeded in breaking through to the Energy Awards event at the Ministry of Energy and Mineral Resources in 2016, has now been selected to be grand finalist National Science Olympiad organized by Pertamina.
The final is planned to be held in November in Jakarta and will compete again with competitors from various regions. For this achievement, the Air Lindi innovation pioneered by Hardiansyah, Gadis Maulina, and Izah from the Faculty of Agriculture, Brawijaya University (UB) received financial support from Pertamina to build an Air Lindi processing installation.
Gadis Maulina, one of the team members, said that before entering the final nomination, their proposal had initially managed to beat hundreds of other proposals from various universities throughout Indonesia and made it into the top 45.
"After that we also managed to eliminate other participants and enter the final round. Grand finale "which will be held from 19 to 25 November," said Gadis, Wednesday (26/10)
The innovation of Leachate Treatment initially emerged when participating in the 2016 Malang City Technology Innovation Competition (Inotek) held by the Malang City Regional Planning and Development Agency (Bappeda) which was then included in various competitions including those held by Pertamina.
Responding to this achievement, the Mayor of Malang, H. Moch Anton, said he was proud because the young people in this City of Education never stop looking for the latest innovations in various fields.
The Mayor, who is familiarly called Abah Anton, added that the many innovations and creations, especially from young people, could have a positive impact on the residents of Malang City.
"Like the innovation of Air Lindi which produces energy, this is a discovery that is quite proud and is recognized by national academics and even by the Ministry of Energy and Mineral Resources," said Abah Anton.
The number one person in the Malang City Government hopes for support and prayers from the community so that the Air Lindi innovation can be the best in the science olympiad event. "The Malang City Government strongly supports innovation and creativity of young people," he added.
The idea of the emergence of leachate innovation began with the fact that the high population growth rate was followed by a fairly rapid urbanization movement, so that waste increased by around 600-800 tons each day. That was what was observed by scientists from UB and saw the potential for waste to produce 800 liters of leachate per day.
In scientific studies, leachate is a liquid produced from the exposure of rainwater to waste piles. This liquid carries suspended and dissolved materials which are waste degradation products, its composition is influenced by several factors such as the type of waste deposited, the amount of rainfall in the TPA (Final Disposal Site) area and the specific conditions of the disposal site.
Contains organic compounds such as Hydrocarbons, Humic Acid, Sulfate, Tannate and Gallate and inorganic compounds such as Sodium, Potassium, Calcium, Magnesium, Chlorine, Sulfate, Phosphate, Phenol, Nitrogen and high heavy metal compounds. So that the existence of leachate accompanied by innovation and technology around the Supit Urang TPA can be used as a source of renewable electrical energy. (say/yon)
