Piles of material suspected to be B3 waste (hazardous and toxic material) were found in Kemloko Hamlet, Jotangan Village, Mojosari District, Mojokerto Regency. The pile of material suspected to be waste from coal with the type of bottom ash and fly ash was discovered first by Gangsar Aji Santoso, Friday (05/31/2019). Gangsar added, the effect that may occur if people exposed by bottom ash is that they will experience itching on the skin. If rain comes and the water absorbs the material, it will pollute the flow of water around and can not be consumed (jatimnow.com, 2019).
