One of the microalgae that are widely used in the industrial world is Spirulina platensis which has high nutritional content of protein, fatty acids, vitamins and antioxidants. In its growth, this microalgae requires media and the addition of macronutrients nitrate and phosphate which greatly affect the growth and productivity of S. platensis biomass. This study aims to determine the effect of nitrate and phosphate concentrations on S. platensis biomass on an indoor scale and to determine the optimal nitrate and phosphate concentrations to achieve maximum biomass. This research was conducted in August 2020 as an experimental method, with culturing S. platensis with the addition of different concentrations of nitrate and phosphate. The design used in this study was a Completely Randomized Design consisting of 5 treatments that are 0 ppm, 10 ppm, 20 ppm, 30 ppm, and 40 ppm, each treatment with 3 repetitions. The source of nitrate and phosphate used is NPK. Water quality parameters during culture with temperatures ranging from 29-30oC, salinity 25-26 ppt, and pH 8. The optimal concentrations of nitrate and phosphate to achieve the maximum biomass is in treatment C (30 ppm) with a total of biomass 0,43 g. Whereas in treatment D (40 ppm) the biomass did not show a significant increase because the dose was too high with a total of biomass only 0,299 g

ABSTRACT This study aims to determine the effect of the optimal dose of cherry leaf extract solution on incubation time, hatchability, and survival of larvae of catfish (Clarias gariepinus). The research used an experimental method using a Completely Randomized Design (CRD) with 5 treatments and 3 replications, namely: (P1) 2,0 gr/l, (P2) 2,5 gr/l, (P3) 3,0 gr/l , (P4) 3,5 gr/l and (P5) 4,0 gr/l. The test eggs used came from artificial spawning at the Fish Seed Center (BBI), Riau Islamic University. The container used is a jar with a capacity of 10 liters of 15 pieces. This research was conducted for 21 days on October 2019 at the Laboratory of Fish Seed Center (BBI), Faculty of Agriculture, Riau Islamic University, Pekanbaru. The results showed that the best adhesion was found on (P5) 4,0 gr/l of 98,89%. The incubation time and hatchability of the best treatment at (P3) 3,0 gr / l, the incubation time is 17 hours 27 minutes with a hatchability of 83,33%. Furthermore, the best treatment life was on (P2) 2,5 gr/l was 42,08%.

The aim of the study was to evaluate the effect of Spirulina platensis, formulation containing microalgal extract, post-extraction residue, and formulation without algal extract (containing only emulsifier) on the content of FAs in the eggs of laying hens. The experiment was conducted on 90 laying hens (ISA Brown) as a completely randomized design. Hens were assigned to five experimental groups (six replicates). The FAs content in eggs was determined after 30, 60, 90, and 120 days of the experiment. There were no statistically significant differences in FA profiles after 30 days of the experiment. It was shown that after 60, 90, and 120 days of the experiment, the investigated additives had a significant impact on the content of such acids as: dodecanoic acid (C12:0), C15:0, nonadecanoic acid (C19:0), myristoleic acid (C14:1 n-5), α-linolenic acid (ALA, C18:3 n-3), DPA, C20:2 n-6, and decosahexaenoic acid (DHA C22:6 n-6). There were also significant differences in total PUFA n-3, PUFA n-6, and n-6/n-3 ratio in eggs. The obtained results suggest that the use of algae extract and emulsifier in laying hens nutrition has the greatest impact on the FA profile in the eggs.

The mortality of tinfoil barb during transportation is relatively high due to the oxygen consumption rate and excretion of these fishes. Therefore, the use of an appropriate anesthetic drug becomes one of the solutions for solving this transportation problem of tinfoil barb. One of the natural anesthetic drugs with potential to be studied is Chromolaena odorata leaves. The purpose of this study is to evaluate the effectiveness of anesthetic compounds from Chromolaena odorata leaves in the closed transportation of tinfoil barb. The experimental design used was a non-factorial completely randomized design that consisted of four treatments and three replications,then followed by a Tukey test to see if there was a significant difference. The experimental treatments were A (0 ml/L of leaves filtrate), B (80 ml/L of leaves filtrate), C (90 ml/L of leaves filtrate), and D (100 ml/L of leaves filtrate). The observed parameters were fish behavior towards unconscious condition, onset time, immotilization time, survival rate, and water quality. The results showed that the shortest onset time was obtained from treatment D (100 ml/L leaves filtrate), namely 58 minutes towards unconscious condition, then the longest immotilization time was also shown by treatment D, which was 371 minutes. The highest survival rates were also shown by treatment D which were 94,33% during transportation and 76,33% during culture. The water quality parameters during the experiment were in an optimum condition of tinfoil barb. Keywords:AnestheticChromolaenaodorataTransportationTinfoil barb

Abstract This study aims to determine the effect of giving Morinda fruit distilation for handling Argulus on Carrasius auratus auratus. The research method that used was experimentally with Completely Randomized Design (CRD) with five treatments and four replications. The used treatment are : medium with Morinda distilation mixed 0% (A), medium with Morinda distilation mixed 2,5% (B), medium with Morinda distilation mixed 3% (C), medium with Morinda distilation mixed 3,5% (D), medium with Morinda distilation mixed 4% (E). The results showed that giving Morinda fruit distillation on Carrasius auratus auratus which have Argulus infest significantly different (p <0.05) with the best treatment in D with six releasing Argulus and that fish can survive within 15 minutes dipping. The lowest treatment result in A (control) with nothing releasing Argulus. Water quality parameters are supporting this research. Supporting parameters measured during the study is the water temperature ranges 27° C, pH 7,5-8,5, DO 8 mg/L to 5 mg/L, and salinity from 0 to 3 ppt. Water quality parameter are still within tolerance limit for Carrasius auratus auratus
