Response of Light Intensity to The Carotenoid Content of Sea Grape Caulerpa sp.

Caulerpa sp. is a green alga that grows naturally in Indonesian waters. shallow seas with calm currents and attaches to coral substrates or sand rock fragments. In Indonesia, this widely used as food ingredient. Contains lignan which beneficial human health, namely its ability prevent the growth of cancer cells. This study aims determine difference number carotenoids different light intensities using controlled containers at Laboratory Fish Production Reproduction, University Mataram. The method was experimental Randomized Block Design (RAK) 30 days maintenance. results showed highest treatment D (3 3000 lux) an average absolute 80 g, specific 0,92 %, stolon length 6,4 cm, carotenoid content. lowest value A (1 500 35 0,44%, 4,6 formula 2,6 content 0.15 mg/g
