ABSTRACT
DITA ANASTASIA SARAH ZURENAHUSLA: Activated Carbon from Tea
Waste to Increase Water’s Physical Quality, supervised by AINUN ROHANAH and SAIPUL BAHRI DAULAY.
The research was aimed to know water’s physical quality after activated carbon applicated which has been roasted carbonized and activated with
H-3PO4and to know the percentation of moisture content, ash content and vollatile
matter of activated carbon which appropriate with quality standard of activated carbon.
The research was done in Agricultural Engineering Laboratory Agriculture Faculty University of North Sumatera from February till April 2016. The method of the research was experimental and literature studying from related sourceswith the experiment,and moisture content, ash content, vollatile matter and water’s physical quality were tested.
The results proved that the application of activated carbon to Deli river water could fix and increase water’s physical quality with the quality standard of moisture content and ash content of 5,35% and 5,20% respectively.
Keywords: tea waste, H3PO4, activated carbon, quality standard of
activated carbon
