<\/p>\nJAKARTA \u2013 Wastes have been always a problem in agricultural sector. The higher the agricultural production, the bigger the problem potentially caused by the wastes.<\/p>\n
<\/p>\n
A number of researchers from the National Research and Innovation Board (BRIN) have managed to create an innovation by using the rice husks and palm boiler ash, the wastes from rice and palm oil production, to produce biosilica product with high economic value.<\/p>\n
Hoerudin, a researcher of BRIN\u2019s Agroindustry Research Center (PRA) said that rice husks and palm boiler ash have a high content of silica. \u201cThe rice husks have silica content of 15-20%, while palm boiler ash up to 50-60%. This silica from living organism we call biogenic silica or biosilica,\u201d he said.<\/p>\n
\u201cFrom 5 tons of harvested rice per hectare and 20 tons of palm fresh fruit bunches per hectare, respectively have around 154 kg and 230 kg of silica,\u201d Hoerudin said in a press release on Monday (22\/7\/2024).<\/p>\n
According to him, out of their researches PRA BRIN has managed to produce a number of liquid and powdered silica products based on raw material of rice husks and palm boiler ash in the forms of nanoparticles.<\/p>\n
