Abstract

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 results of measurements of water quality parameters in this study had temperatures ranging from 290 C - 340 C, pH 6,0-6,5, ammonia between 0,28-0,97 and DO range between 3,14-3,81.

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

The purpose of this study was to determine the effect of the combination of chicken manure and buffalo manure on the growth and production of maggot and to determine the percentage of the best combination of chicken manure and buffalo dung on the growth and production of maggot. This study used a completely randomized design with five treatments and three replications, consisting of treatments P1: Chicken Manure (100%), P2: Buffalo Manure (25%) + Chicken Manure (75%), P3: Buffalo Manure (50%) + Chicken Manure (50%), P4: Buffalo Manure (75%) + Chicken Manure (25%), and P5: Buffalo Manure (100%). The results showed that the best treatment was found on P2: Buffalo Manure (25%) + Chicken Manure (75%) with maggot weight growth of P2 0.143 g, maggot length growth of 1.49 cm, maggot daily growth rate of 1.02%, and 93.00 gr for maggot production.

Abstract

This study aims to determine the effect of the long soaking of silkworms (Tubifex sp) in turmeric flour solution on the dilution and growth of baung fish fry (Hemibagrus nemurus). The method used is a Complete Randomized Design (RAL) with 5 treatments of 3 tests, namely P0 treatment = no soaking, P1 = Soaking for 20 minutes, P2 = 25 minutes, P3 = 30 minutes and P4 35 minutes. The baung fish used are fry that are 8 days old with an average weight of 0.09 gr / tail with a length of 0.70 cm / tail. The seeds were obtained from Saprizal's UPR in Padang Mutung village, Kampar district. From the results of the study, the highest dilution was obtained in the P4 treatment by 100% and the lowest in P0 by 97.33%. The highest absolute weight growth of P4 treatment was 0.57 gr and the lowest was 0.37 gr. The highest absolute length growth in the P4 treatment was 3.46 cm and the lowest was 2.99 cm. The highest daily growth rate of P4 treatment was 0.08% and the lowest was 0.05%. The best feed conversion value is P4 treatment of 0.463%. Water quality parameters are temperature 28-30 0C, pH 6.13-7.69, dissolved oxygen 3.4-6.3 mg/L and Ammonia 0.88-4.22 mg/L.

Abstract

This study aims to determine the effect of giving a combination of tofu pulp and fermented bread on the growth and production of maggots. The method used is a complete Randomized Design (RAL) 5 treatments with 3 tests, namely, P1: Tofu dregs (100%), P2: tofu dregs (75%) + afkir bread (25%), P3: tofu dregs (50%) + afkir bread (50%), P4: tofu dregs (25%) + afkir bread (75%) and P5: afkir bread (100%). The results of the study obtained the best combination of nutrients, namely P3with a weight growth of 0.236 gr and a length growth of 2.00 cm. From the results of the protein content test, the highest maggot protein at P5 was obtained at 43.09%. While the measurement of maggot media obtained a temperature of 34-40oC and a pH of 4.5-7.
