Microalgae Dunaliella salina (Teodoresco, 1905) Growth Using the LED Light (Light Limiting Dioda) and Different Media

The purpose of this research was to analyze the growth of Dunaliella salina (Teodoresco, 1905) with different media types and based light source of LED as well as obtaining the optimum media and light source that generate the highest growh of D. salina. The data was analyzed using ANOVA. The material used was D. salina which cultured on 3 L bottles, with three treatments and three replications. The treatments given were respectively Walne Jepara, Walne Lampung, and Za added with NPK, which were then illuminated by using red LED and blue LED. The density of D. salina cells were determined using a light microscope with a Neubauer chamber. The highets result of D. salina density is 8.504 × 104 cell · mL–1 which produced by the red LED treatment in the media of Walne Jepara. The results of blue LED treatment showed that D. salina density was 5.768 × 104 cell · mL–1 with Walne Jepara.
