Rumput laut (seaweed) atau alga merupakan bagian terbesar dari tanaman laut dan komoditi ekspor yang potensial untuk dikembangkan. Indonesia memiliki lima jenis rumput laut yang bernilai ekonomis tinggi sebagai komoditi ekspor dan juga dikonsumsi domestik yaitu Eucheuma sp., Glacillaria sp., Gelidium sp., Sargassum sp. dan Hypnea sp. E. cottoni dan E. spinosum merupakan spesies alga merah penghasil karaginan dan andalan eksport Indonesia. Rumput laut jenis ini banyak dibudidayakan di Propinsi Maluku khususnya di Kota Ambon dan Kabupaten Maluku Tenggara Barat. Tujuan dari penelitian ini adalah menentukan sifat fisiko-kimia semi refined carrageenan (SRC) E. cottonii yang berasal dari Desa Waiheru, Kota Ambon dan Desa Lermatang, Kabupaten Maluku Tenggara Barat. Metode penelitian adalah deskriptif. Analisis meliputi perhitungan rendemen, fiskositas, kekutan gel, kadar air, abu dan sulfat. Hasil pengamatan sifat fisiko-kimia SRC dari desa Lermatang Kabupaten Maluku Tenggara Barat rendemen yaitu 26,8%, fiskositas 60,80 cP, kekutan gel 100 g/cm2, kadar air 15,79%, abu 21,24%, dan sulfat 13,27%, dan SRC dari desa Waiheru Kota Ambon dengan rendemen 24,73%, fiskositas 121,60 cP, kekuatan gel 700 g/cm 2, kadar air 16,04 %, abu 15,26%, dan sulfat 12,34%.

“…Kualitas karaginan berkaitan erat dengan faktor-faktor pada saat budidaya, pemanenan, dan penanganan pascapanen serta metode ekstraksinya (Wenno et al, 2012). Berbagai metode ekstraksi telah banyak dilakukan, satu diantaranya adalah penggunaan larutan alkali untuk menghasilkan karaginan yang bermutu dan bernilai ekonomis tinggi.…”

“…Nilai ini sangat besar jika dibandingkan dengan penelelitian Diharmi et al (2011) yang melaporkan hasil kadar abu tak larut asam hanya sebesar 0,30%. Rendahnya kadar abu tidak larut asam menunjukkan karaginan yang tidak banyak terkontaminasi selama proses penanganan bahan baku dan pengolahan (Wenno et al, 2012).…”

Carrageenan is a gelling form of polysaccharide obtained from extraction process of red seaweeds (Rhodophyceae) including Kappaphycus alvarezii. Carrageenan is widely used for pharmacy, cosmetics, food, gelling, and binding agent as well as emulsifier and stabi-lizer. The quality of carrageenan is affected by several factors, one of them such as concen-tration of KOH. The objectives of this research were to define the best concentration of KOH for extraction and characterize the functional properties. Functional properties of carrageen-an in this research were sulphate content, acid insoluble ash, gell strength, fiber, and whiteness. The experimental design used for this research was completely ran-domized design with four treatments of KOH concentrations i.e. 1%, 3%, 5%, and 7%. The study showed that the use of KOH concentarion of 7% resulted the best of carrageenan quality containing 24.36% sulphate, 1.96% acid insoluble ash, 17.80 g/cm2 gell strength, 8.94% fiber and 58.91% whiteness. Keywords: carrageenan, extraction, functional properties, Kalium Hydroxide, Kappaphycus alvarezii

Seaweed Kappaphycus alvarezii is a pre-eminent commodity in the field of marine and fisheries Indonesia which has been widely cultivated in coastal waters. Currently, the main problem faced by the cultivators is the limited stock of seeds, both in terms of quality and quantity. Selection is one method that is expected to increase the rate of seaweed growth quickly, cheap, easy, bulk, and sustainable.This study aims to determine the effect of selection on the growth of seaweed so that it can be done superior seed production for cultivation purposes. Seaweed cultivation was done in Kulu Village, Wori District, North Minahasa Regency, North Sulawesi by using long line method in April-June 2015. Selection is based on the daily growth rate parameter (DGR) and the selection method refers to the selection protocol that has been developed on K. alvarezii seaweed. Results showed that DGR of selection seedlings were higher (P <0.05) compared to controls, in which DGR of selection reached 5.87%/day, while DGR of control was 1.89%/day. From three seed production cycles (G-1 - G-3), the average DGR resulted from the selection was 5.53%/day and control 2.19%/day. Carrageenan content of selection result is relatively higher (47.66%) than control (31.28%) with mean for three cycle (G-1 - G-3) that is 43.55% for selection and 33.20% for control. Water quality (temperature, salinity, nitrate, phosphate) during the study is still within the appropriate range for seaweed growth. Therefore it is concluded that with the application of the method of seaweed selection can increase the daily growth rate and carrageenan content of seaweed K. alvarezii which directly affects the increase of production both in quantity and quality.
