The effect of fermentation time and different raw materials on N and P content as nutrient sources of Caulerpa sp. organic

Caulerpa sp. seaweed. is one of the seaweeds being developed because it has great potential in addition to being consumed by humans but in the cultivation of Caulerpa sp. Fertilizer is needed as a source of nutrients for growth. The purpose of this study was to determine the length of time and raw materials containing the highest nitrogen and phosphate that can be used as fertilizer as a source of nutrients Caulerpa sp. The design used is a factorial pattern design with a completely randomized basic design. As for what was tested, factor A was the length of fermentation time (14, 16, and 18 days) and the second factor was raw materials (bean sprouts, Gracillaria sp. seaweed, and banana weevil). The results showed that different treatments for fermentation time and raw materials had a significant effect (p<0.005) on Nitrogen and Phosphate content.153,398ppm and 25,585ppm.
