Abstract

Culture media is one useful aspect for the development of microalgae. Adding fertilizer to the culture media can affect the density of Chlorella sp. When carrying out culture, it is necessary to have liquid organic fertilizer (POC) which is easy to obtain and found in nature, especially liquid organic fertilizer made from a fermented mixture of rice water, coconut water and eco enzymes. This research seeks to determine the effect of density of Chlorella sp. by administering liquid organic fertilizer made from rice water, coconut water and Eco enzyme fermentation, we can find out the ideal dose needed for the growth of chlorella sp. The highest throughout the study was obtained in treatment A (dose of 5 ml eco enzyme), which was followed by treatment C (does 12 ml/l POC + 2 ml/l eco enzyme), treatment B (does 8 ml/l POC + 2 ml/l eco enzyme), and the lowest in treatment D (dose 16 ml/l POC + 2 ml/l eco enzyme). Providing liquid organic fertilizer with rice washing water and coconut water had a significant effect on density of Chlorella sp. (p value <0.05). The highest density occurred on day 6 in treatment C, where a mixture of rice washing water and coconut water containing 5 ml of eco enzyme produced a population density of 6996.67 x 104 cells/ml.

Abstract

Chlorella sp. has significantly higher nutritional content compared to artificial feed. To obtain Chlorella sp. as a natural feed, it was necessary to cultivate pure phytoplankton to meet the availability of crude feed in sufficient quantities. In conducting the cultivation, there was a need for liquid organic fertilizer (LOF) that could be easily obtained and was available in nature, which was liquid organic fertilizer made from a mixture of rice washing water and coconut water fermented using EM4. This research aimed to determine the density of Chlorella sp. using liquid organic fertilizer from rice washing water, and coconut water fermented using EM4 and the effect of the best fertilizer dosage on the growth of Chlorella sp. This research used a Completely Randomized Design (CRD) consisting of 4 treatments with four replications. The highest average cell density of Chlorella sp. throughout the research was obtained in treatment C (15 ml dosage), followed by treatment B (10 ml dosage), treatment D (20 ml dosage), and the lowest in treatment A (control). The application of liquid organic fertilizer from rice washing water and coconut water significantly affected the density of Chlorella sp. (p <0.05). The highest density was recorded on day 6 in treatment C with a dosage of rice washing water and coconut water of 15 ml, with a population density of 12,466.25 x 104 cells/ml.

Abstract

Chlorella sp. is one of the microalgae that is used as natural food because it contains more nutrients compared to artificial food. In order to obtain microalgae such as Chlorella sp. The aim of the cultivation process is to obtain microalgae in good condition, so that the availability of natural food can be fulfilled through the culture process. To support the culture process, organic materials are needed in the form of POC which are easy to find and of course naturally available. One example is the use of POC organic material which is produced from adding coconut water, rice washing water and chicken egg shells, then fermented using EM4. The aim of this research was to determine the effect of using liquid organic materials (POC) on the density of Chlorella sp. and the best concentration treatment during the long-term culture process. The research method applied was a Completely Randomized Design (CRD), including four treatments and three repetitions throughout the research. Chlorella sp cell density. The highest occurred in treatment K (control concentration 25 ml/container), then treatment B (concentration 200 ml/container), treatment A (concentration 100 ml/culture container), and the lowest density was in treatment C (concentration 300 ml/container). The use of ingredients (POC) derived from coconut water, rice washing water, and chicken egg shells has an effect on the cell density of Chlorella sp. with a p value <0.05). The highest density was on day 10 with a density value of Based on the results obtained from the use of POC as a natural fertilizer for the cultivation of Chlorella sp. For this reason, it is hoped that cultivators need to use POC in the surrounding environment as an alternative fertilizer to replace chemical fertilizers because it has good nutritional content for the Chlorella sp cultivation process and does not pollute the aquatic environment.
