Abstract

The goal of this research was to observe the effects of yeast on the density rate of Alona sp. with various concentrations compared to the density rate in horse manure media. The treatments are as follows, treatment A yeast 30 mg yeast/0.5 L water, treatment B yeast 10 mg yeast/0.5 L water, treatment C yeast 5 mg yeast/0.5 L water, treatment D yeast 1 mg yeast/0.5 L water, treatment E 0.5 L well water, treatment F horse manure media (horse manure 10 gr, soil 50 g in 0.5 L water). The research was carried out for two weeks, and the density calculation was done once a week. The results obtained based on Anova One Way analysis are that yeast with different concentrations does not have a significant effect on the density of Alona sp. Nevertheless, it was concluded that the giving of yeast to Alona sp. is much more efficient and effective compared to horse manure media, because it is more hygienic, easy to obtain and not expensive, also from nutritional value, yeast has a higher value compared to horse manure media. The measuring of water quality parameter during the research was temperature around 26-30°C.

Abstract

The purpose of this research was to investigate the population density of Alona sp. on yeast media with different concentrations. The study was conducted using a completely randomized design (CRD) consisting of 5 treatments and 3 replications for 21 days. The treatments given were A: 10 ppm yeast, B: 5 ppm yeast, C: 1 ppm yeast, D: horse manure, and E: well water. The initial stocking density of Alona sp. for each treatment was 15 individuals/300 mL of well water. The water quality parameter measured during the study was temperature. The results of the one-way ANOVA test showed that there were significant differences between treatments on the density level of Alona sp. (p <0.05). Tukey's further test showed that treatment B was the best with a density of Alona sp. as many as 8059 individuals/300 mL of well water. The temperature during the study, in the morning was 26 ± 0.52°C and in the afternoon was 26 ± 0.46°C.

Abstract

The purposes of research were to examine the effect of extract of Acalypha indica leaf on the growth of Nile tilapia and determine the dose of leaf extract that could enhance the growth of tilapia optimally. The fish used were Nile tilapia taken from the Tatelu Center for Freshwater Aquaculture with an average weight of 3.79±0.50 g. The medicinal plant A. indica was collected from around the Faculty of Fisheries and Marine Science complex and from the North Bolaang Mongondow area. After being washed, the leaves were dried and then ground to obtain leaf powder. Leaf flour was then extracted by maceration method with 95% alcohol solvent. After being concentrated, the extract was then used as a treatment with different concentrations, including A: 0 g extract/kg feed, B:10 g extract/kg feed, C:20 g extract/kg feed, D:30 g extract/kg feed and E: 40g extract/kg feed. The data collected consisted of absolute growth, daily growth and relative growth. The results showed that the extract of A. indica leaf added to the feed had a significantly effect on the growth of tilapia indicated by an increase in absolute growth, daily growth, and relative growth (p<0.05). The best fish growth was achieved in fish fed with feed with the addition of 20 g extract/kg feed. In conclusion, leaf extract of A. indica can increase the growth of Nile tilapia

Abstract

The objective of this study was to determine the difference in density of Alona sp in fermented rice straw and unfermented rice straw media. This research was conducted at the Aquaculture Technology Laboratory and the Fish Health, Environment and Toxicology Laboratory, Faculty of Fisheries and Marine Sciences, Sam Ratulangi University, Manado, from March to June 2021.The experiment was based on four treatments, namely fermented rice straw media with Effective Microorganisms-4 (EM-4) solution, unfermented rice straw media, horse manure media and water media. The experimental design used was a completely randomized design (CRD) with 4 treatments, each treatment was repeated 3 times, so there were 12 experimental units. The results obtained are the density of Alona sp. cultured on fermented rice straw media were not significantly different from those cultured on unfermented rice straw media but significantly different from horse manure and water media. There was no significant difference between fermented straw media and unfermented straw media on the increase in density of Alona sp., apparently caused by the fermentation time of EM-4 solution of rice straw which was not long enough.
