Seaweed Farming

The most commonly employed methods of seaweed farming are Off-Bottom method and Long-Lines method, for Off-Bottom method seaweeds are tied to a rope supported by stakes at height about 30cm above sea floor, this method only used in shallow water. Long-Lines method uses long rope (between 50 to 100m) tied to an anchor and supported by several buoys, usually an empty plastic bottle, long lines method keep seaweed at floating around sea surface so that it can continously receive direct sunlights.

A new farming method also been introduced such as Floating Cage which keep seaweeds afloat below sea surface with a help of special cage made of plastic pipe protected with nets, to keep the seaweed from being eaten by harmful organism such as fish.

It takes between 45 to 60 days for seaweed before it can be harvested, farmer can add fertilizer if needed to stimulate the growth of seaweed, after harvested seaweed can be sell directly or dried for higher price.

Seaweed Drying

Drying seaweeds usually takes around 2-3 days depending on the intensity of the sunlights, type of seaweeds and moisture requirement. There are several drying methods commonly employed for drying seaweeds, these methods are Direct Ground, Tarpaulin, Para-para Bed and Hanged.

  • Direct ground, seaweeds are dried on top of the ground without any base, we avoid this kind of drying process because it introduce more impurities to our products
  • Tarpaulin, seaweeds are put on top of tarpaulin, allows heat to be distributed evenly, this is the most commonly uses method for seaweed drying (and other type of commodities such as dried cloves)
  • Para-para Bed, seaweeds are placed on top of net supported by bamboo structure, this method allows water and seaweed secretion to drip to the ground
  • Hanged, seaweeds are hanged to a wire (without touching the ground), this considered the best method recommended by SNI2690:2015, it reduces impurities and speed up drying process


There are many application for seaweeds based products such as Carrageenan E407 which is a compounds derived from Eucheuma Cottonii or Eucheuma Spinosum or combination of both, Semi-Refined Carrageenan (E407a) in form of dried seaweed either Dried Eucheuma Cottonii or Dried Eucheuma Spinosum, application of Carrageenan are ranging from Meat Binder, Food Stabilizer, Cocoa Suspension or Cosmetic.

Unlike Eucheuma Cottonii or Eucheuma Spinosum, Gracilaria Sp are usually extracted for it's polysaccharides, pollysacharides is long chain of polymeric carbohydrates which is used to create Agar (E406), Agar mostly used for manufacturing Jelly or Yoghurt. Because of the nature of seaweeds which is source of polysaccharides, seaweeds can be bio-converted into bio-ethanol through hydrolisis process by converting those polysaccharides into fermentable sugars.

Another application for seaweed based products are for cattle feed, seaweeds are being used as cattle feeds which is the largest contribution of methane gases, seaweed based cattle feed could cut cattle methane emission up to 80%. Another use of seaweed is for bio-plastic, which uses polysaccharides as natural biopolymers, bio-plastic only accounts for 0.2% for global polymer markets but it keeps increasing at steady pace at 16.2% Compound Annual Growth Rate (CAGR) and will reach 19.93 billion by 2026.
