General kind of seaweed that species of sargassum crassifolium is browm colored cause the domination pigment fikosantin covered the clorofil pigment until the algae seen as brown. Thallus branching saragassum crassifolium molded formation two-two not be arranged that contrast at especially length side thallus that called (pinnate alternate). Leaf at algae is oval- shaped with big size about 40 mm and wide about 10 mm. It grow wider and serrated with slippery surface. It has thallus formed flat with leafy branches alternately resemble to land plant. in the surah Al- an‘am / 6 : 141

In edge shave serrated has bubble had called vesicle. This bubble air functions as defend leaf in order to surface of the water. Diameter bubble from about 15 mm with flat and wing size. Reproduction sargassu crassifolium consist to two wind, the first reproduction is vegetative and secondly is generative. The vegetative reproduction is doing by fragmention, In a generative manner is multiply individual pass through to antheridia and oogenia. In depth womb compound active among others in amino sour, mineral, alginate, and also extra positive contained the flavonoid, triterpenoid, and saponin.

  1. Algiant, used in store industrialization drag as emulsifier, stabilizer, suspended agent in tablet production and capsule.
  2. Cosmetic, used to pulverizer in cream production, lotion and salve.
  3. Food , used as stabilizer enulsifer, thickener, additive, or addition material in textile industrialization.
  4. Agar, much using in industrialization/ sector : paper, ceramics, photography and excetera.
  5. Microbiologiacal used to culture media.
  6. Cultivation.


B. The Kinds of Seaweed

kinds of seaweed the author will explain, they are :

1. Gelidium Sp

Seaweed of this kind is part of species rhodophtya (red seaweed). Red color in seaweed of pigment fikoeritrin, It has long about 20 cm and wide about 1,5 mm.

2. Gracilaria Verrucosa

Seaweed of this kind from is resemble to the root, leaf stick of fruit. Its shape characteristic is thin to cylinder from that is not branching uniform.

3. Eucheuma Spinosum

C. The Classification and Characteristic of Seaweed

Classification of Seaweed:
  • Kingdom : Plantae
  • Class : Rhodophyta
  • Ordo : Gigartinales
  • Family : Solieriaceae
  • Genus : Eucheuma
  • Spesies : Eucheuma Cottonii
  • Division : Rhodophyceae
Algae was classified into seven division, based on the pigmentation in algae’s body, they are :

1. Cyanphyta Division (blue algae)

It lives in most place, fresh water and lives in temperature about 0-75 from some clans that free life, epifit, epizoik, endofit and clings waters bottom, also simbiosis. Body’s structure is uniseluler and photosynthesis to gets flour and sianofisin (like protein). in the al-Qur’an surah al-fatir :12

وَمَا يَسْتَوِى ٱلْبَحْرَانِ هَٰذَا عَذْبٌ فُرَاتٌ سَآئِغٌ شَرَابُهُۥ وَهَٰذَا مِلْحٌ أُجَاجٌ ۖ وَمِن كُلٍّ تَأْكُلُونَ لَحْمًا طَرِيًّا وَتَسْتَخْرِجُونَ حِلْيَةً تَلْبَسُونَهَا ۖ وَتَرَى ٱلْفُلْكَ فِيهِ مَوَاخِرَ لِتَبْتَغُوا۟ مِن فَضْلِهِۦ وَلَعَلَّكُمْ تَشْكُرُونَ

2. Chlorophyta Division (green algae)

Divided into two species, they are :

(1) Chlorophyceae

Have doing photosyinthesis process to get amilum and grease proliferated to sporik and gemetes

(2) Charophyceae (coral algae)

Body’s structure is uniseluler and poliseluler. Proliferated to vegetative and gametes.

3. Euglenophyta Division

Live as zooplankton and endozoik, proliferated to longitudinal cleared.

4. Phyrophyta Division (fire algae)

Its revolve movememt, lives in sea and freshwater has clorofil pigmentation, are “a” and “c”

5. Chrysopyta Division (golden algae)

Divided into three species they are :

(1) Xanthophyceae

Yellowish dominant colored with character life in adhere and free

(2) Chrysophyceae (golden algae)

(3) Bacillariophyceae (rustle or diatome algae)

6. Phaeophyta Division (brown algae)

Body’s structure is multiseluler and divided into leaf, stalk,and bus as root. Its food reserve similar to manitol (alcohol chem) and laminarin (carbohydrate chem)

7. Rhodophyta (red algae)

Body’s structure is multiseluler and uniseluler, with food reserve similar to florida flour.

Characteristic of Seaweed

Seaweed grow in all hydrofis until to order on sunshine depth to achieve it. Seaweed lives as fitobento with adhere it self mod subrat, sand and excetera.

Proliferation into two kinds, are: generative between male gemetes and female gametes, vegetative, conjugative and response. The suitable salinity waters to this clan is about 15-34 ppt. Seaweed needs strong activation on of water and adhere to hard subtract, cause inventing in hindian ocean state.

Which one of charming seaweed’s character is haven’t spora or swimming gametes with tremble hair or whipping.
