Abstract:
World seaweed production in 2020 published by the Food and Agriculture
Organization of the United Nations (FAO), Indonesia was ranked second as the largest
seaweed producer with production of 10.8 million tons. The aim of this research is: To
analyze the characteristics of seaweed liquid waste at PT. XYZ. To design a seaweed liquid
waste processing process at PT. XYZ based on physics-chemistry as recycled water.
Methods include analysis and experiments. This method is used to analyze the
characteristics of liquid waste and determine the design of the seaweed liquid waste
processing process at PT. XYZ. Research results: The characteristics of the seaweed liquid
waste produced do not meet the quality standards in Kep.08/Men. LH/2009 concerning
Industrial Waste. A physic-chemical based liquid waste processing process with
neutralization, filtering and aeration can be used as recycled water in the alkali treatment
process.
