Abstract

This study aims to determine the effect of the use of a combination of lemna minor substrates and mud on the biomass of the population of Tubifex sp. This research is experimental, with a completely randomized design (CRD), with five levels of treatment P1 = 100% (lemna minor ) + 2,000 gr (mud), P2 = 75% (lemna minor ) + 2,000 gr (mud), P3 = 50 % (lemna minor ) + 2,000 gr (mud), P4 = 25% (lemna minor) + 2,000 gr (mud), P5 = 0% (lemna minor) + 2,000 gr (mud). Data obtained from research results in analysis of variance (ANOVA) and in further testing with the Smallest Significant Difference test. The main parameters observed were the number of population and biomass of Tubifex sp. The results of the study showed that the combination of Lemna minor substrate and mud significantly (p <0.05) on the growth of biomass and the population of Tubifex sp. The best results were found in the treatment with the treatment formulation P1 = 100% (lemna minor ) + 2,000 gr (mud) which produced a population of 6,250 ind / gr and biomass 8.60 gr / m2.

Abstract

This study aimed to determine the effect of caffein with various doses on the survival rate and gorwth of galah shrimp (Macrobrachium rosenbergii). This research using completely randomized design with five treatments and three replications. Caffeine is given through the feed at a doses 0,0; 0,5; 1,0; 1,5; and 2,0 g caffein/kg feed. The result showed that applied caffein in commercial feed has a significant effect (P < 0,05) on the survival rate of galah shrimp. And no significant effect (P > 0,05) on absolute weight growth and relative growth rate of galah shrimp. Survival rates range from 35% - 80%, absolute weigh growth range from 0,4 – 0,46 g and relative growth rate range from 1,05 – 1,31% / days. The best treatment is P5 (2 g caffein/kg feed) with an 80% survival rate; and 0,46 g absolute weight growth; and 1,31% / days relative growth rate. pH range from 6,4-7,4; temperature range from 25-30 oC. The results of these water quality parameters indicate normal water quality for galah shrimp survival.
