Pengaruh Pemberian Pupuk Cair Azolla Microphylla Terhadap Pertumbuhan Populasi Nannochloropsis Oculata Skala Laboratorium

---

Nannochloropsis oculata is a microalgae that is often used as natural food for fish larvae. In general, microalgae cultivation uses standardized Walne fertilizer. This dependence causes the need to develop alternative natural liquid fertilizers such as Azolla microphylla. This research uses an experimental method which aims to determine the effect of administering A. microphylla liquid fertilizer at different doses on the growth of the N. oculata population on a laboratory scale. This experiment began with making A. microphylla liquid fertilizer, preparing cultivation and cultivation media as well as calculating the population density of N. oculata and checking the water quality of the cultivation media in September-October 2022 at the Experimental Pond Laboratory, Biotechnology Laboratory and Marine Biology Laboratory, Department of Marine Science, Faculty of Fisheries and Marine, Riau University. This research used a Simple Completely Randomized Design (RALS) with 4 treatment levels and 3 replications. The treatment used A. microphylla liquid fertilizer with doses A (2 ml), B (3 ml), C (4 ml) and D (Walne fertilizer control). RALS analysis was carried out in IMB SPSS Statistics software on the peak day of N. oculata growth. The results showed that the highest population density was in treatment D (control) on day-6 with a value of 483.5 x 105 (cells/ml) and treatment C (4 ml A. microphylla fertilizer dose) on day-5 with a value of 437. 3 x 105 (cells/ml). The results of the ANOVA test showed a significance value of 0.007 < 0.05, which indicated that there was a real effect (significantly different) between the treatment of A. microphylla liquid organic fertilizer at different doses on the density of N. oculata. Relatively, the growth rate of N. oculata in treatment D (giving Walne fertilizer) was still the highest with a value of 170.868% and treatment C with a percentage of 145.005%. Furthermore, the specific growth rate in treatment B was the highest with a value of 1.730% on day-4. The Walne liquid fertilizer treatment which was the control was still higher and dominated the population and growth rate of N. oculata and could not be replaced with A. microphylla liquid fertilizer.
