Abstract

ABSTRACT This research was conducted for 21 days starting from November 12 until December 2, 2017. Located at the Seed Fish Hall (BBI) Faculty of Agriculture, Islamic University of Riau Pekanbaru. The purpose of this research is to know the effect of silkworm with the different percentages on the survival and growth of baung larvae (H. nemurus). The method used was an experimental method using Completely Randomized Design (RAL) with 4 treatments and 3 replications namely, P1 (Giving silkworm 3%/fish weight), P2 (Giving silkworm 6%/fish weight), P3 (Giving silkworm 9%/ weight of fish) and P4 (12% silkworm/fish weight). The test fish used were larvae of 3-day-old bamboo fish with an average weight of 0.02 gr and an average length of 0,7 cm. Larva baung fish obtained from the spawning in the Seed Fish Hall (BBI) Faculty of Agriculture, Islamic University of Riau Pekanbaru. The container used is 10 liters or 10 liters capacity. From the research result, the best survival percentage on P4 is 90%, then P3 is 89%, then P2 is 87% and the lowest at P1 is 85%. The absolute and absolute highest absolute growth is found in P4 weighing 0,28 gr and length 2.13 cm, then P3 weighing 0,27 gr and length 2,10 cm, then P2 weighing 0,26 gr and the next 2,07 cm length lowest on P1 weighing 0.24 gr and length of 2,03 cm. The highest daily growth rate was also found in P4 13,81%, P3 13,57%, P2 13,32%, and the lowest in P1 was 13,05%. Keywords: Silk Worms, Survival, Growth, Baung

Abstract

This study aims to determine the effect of giving POC with different time ranges on abundance. The study was carried out for 18 days in the Microalgae Laboratory of the Fish Seed Institute of the Faculty of Agriculture, Riau Islamic University, Pekanbaru. The method used is a completely randomized design (CRD) with 5 treatments 3 replications, namely: P1 giving POC on day 5, P2 giving POC on day 6, P3 giving POC on day 7, P4 giving POC on day -8 and P5 administration of POC on the 9th day. From the results of the study, the highest density of Chlorella sp was found on P3 treatment with a total density of 9,833,333 cells/ml on the 5th day. The lowest average peak was in the treatment of P1 with 2,566,667 cells/ml on the 12th day. Water quality such as temperature ranged from 25 to 300 C and pH between 6.5-7.

Abstract

"Giving vermicompost POC with different doses to the increase in the population of Chlorella sp." The research was carried out for 23 days starting from 10 April 2018 to 3 May 2018, at the Microalgae Laboratory of the Fish Seed Center, Faculty of Agriculture, Riau Islamic University, Pekanbaru. This study aims to determine the effect of giving vermicompost POC with different doses on the increase in the population of Chlorella sp. The method used was a completely randomized design (CRD) with 5 treatments and 3 replications, namely: P1 administration of vermicompost POC at a dose of 0.5 cc/l, P2 giving vermicompost POC at a dose of 1.0 cc/l, P3 giving vermicompost POC at a dose of 1,5 cc/l, P4 was given vermicompost POC at a dose of 2.0 cc/l and P5 was given vermicompost POC at a dose of 2.5 cc/l. From the results of the study, the highest density of Chlorella sp was in treatment P2 with a total density of 14,500,000 cells/ml on day 11. With the lowest average peak in treatment P5 with a total cell count of 6,333,333 cells/ml on day 4. Water quality such as temperatures ranging from 25-30 0C, pH 6.5-7.
