Pengaruh Kerapatan Biorafia Terhadap Penurunan Kadar Logam Berat (Pb Dan Cr) …
One of pollutants that enter the Sail River is heavy metal. Efforts to reduce the level of heavy metal (Pb and Cr) can be conducted by using biocords. In this research the biocord fibers were replaced with raffia fibers (biorafia). To understand the effect of biorafia density toward the decreasing level of heavy metal such as Pb and Cr on the water of the Sail River, a research has been done in…
