KAJIAN PRODUKSI TEPUNG ATC (ALKALI TREATMENT CARRAGEENAN) DI TINGKAT PETANI RUMPUT LAUT DENGAN MENGGUNAKAN PELARUT KOH

Abstract

Seaweed is a biological resource that many found in Indonesia. The use of seaweed in Indonesia
as a source of food is still limited. While seaweed has a bioactive compound that is very benefcial
for health. Seaweed processing among seaweed farmers is still very limited. So far, seaweed
farmers process seaweed into dry form only, not yet made into semi-fnished products. The
purpose of this research was to learn how to extract seaweed that can be applied at the level of
seaweed farmers to produce ATC (alkali treatment carrageenan) which contains fber, calcium,
and natural iodine. The extracting solution used was KOH with concentrations of 6%, 7%, and
8%. The yield of ATC (alkali treatment carrageenan) obtained from seaweed extraction process
with 8% KOH yields the highest yield (32,5%), ash 12,03%, carbohydrate 24,93%, and calcium
927,15 mg / l. The extraction of seaweed with KOH 6% yields the highest crude fber (23,62%)
and iodine 8,36%.
