Abstract

Leachate, as liquid waste is rich in nutrients, can be used as organic material for the microalgae culture such as Chlorella sp. This study aims to determine the effect of different concentrations to of leachate on the abundance of Chlorella sp populations. The observation was conducted at the laboratory of Microalgae, Agriculture faculty, Islamic University of Riau. The method used in this study was an experimental method using a randomized design; one factor, namely the different concentrations of leachate with five levels, were  5%, 10%, 15%, 20%, and 25%/l of water and three replications. The testing organism in this study was phytoplankton Chlorella sp. The culture container used was a gallon with 20 L of capacity and a water volume of 16 L. The measured parameters were cell abundance, specific growth rate, and water quality. The obtained results showed that the highest abundance of Chlorella sp at a concentration of 25% at 7,322,222 cells/ml, and the peak on day 16, the lowest concentration of 5%, was 2,580,556 cells/ml. On the sixth day, the highest specific growth rate was at a concentration 5% at 0.195/day, and the lowest was 20% at 0.077/day.

Abstract

The study aims to determine the feeding of different products on the growth of the fish slice. Culture vessel in the form of net bags of 1 x 1 x 1.2 (m) of 9 bags with stocking density 20 birds. The method used experiment with completely randomized design (CRD), three treatments and three looping. Such treatment is P1 = Feeding Comfeed products, P2 = Feeding Sun products, and P3 = Feeding Charoen Pokphand products. From the results of research feeding with different products derived growth to slice fish weight of 17.23 grams P1, P2 was 19.26 grams, and P3 of 17.83 gr. The growth of the fish slice length of 4.13 cm for P1, P2 and P3 of 5.30 cm is 27 cm. The growth rate of daily weight of the fish slice to P1sebesar 2.13%, with a value of 2.27% P2 and P3 of 2.19%. Slice fish mortality during the study for as many as 1 tail P1, P2 and P3 2 tails as much as 1 tail. For all three types of feed of different products is not a significant effect on the growth of the fish slice. Water quality parameters for such a study, the water temperature ranges from 25-28 ° C, acidity (pH) of 5-8, dissolved oxygen (DO) between 5.97 to 6.38 ppm, and ammonia (NH3) between 0.19 - 0.32 ppm. Value parameter water quality of Lake Betung waters during the study still supports for the life and growth of fish slice.
