Tingkat kepadatan populasi Alona sp. pada media tumbuh ragi
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.
