Abstract

Seaweed is one of the strategic commodities in fisheries revitalization program in Indonesia. The problems faced by seaweed producers are the low quality and products diversification of seaweeds due to traditional post-harvest handling and unknown critical factors as quality benchmark of seaweeds products. This study was aimed to determine the condition of the quality of raw materials and end products that have been produced on the market and give recommendations for better seaweed processing technology. The steps taken were the collection of data and information, purchase of raw materials and seaweed based food products, analysis of various seaweed products purchased from the survei areas, process improvement based on the results of analysis, and product analysis as the results of process improvement results.
