Abstract

This study aims to estimate the wealth and stability of traditional and intensive brackishwater pond waters through biological index calculation (diversity, uniformity and dominance of plankton) in traditional and intensive brackishwater pond waters of Probolinggo Regency, East Java Province. Sampling plankton and water from the site, considered to represent the diversity of plankton and water stability of traditional and intensive brackishwater pond. Plankton was collected using a plankton net no. 25, then preserved using 1% lugol solution. Measurement of water quality variables include temperature, salinity, dissolved oxygen and pH, whereas the laboratory analyzes that Total Organic Matter (TOM), NO2, NO3, NH3, PO4, Total Suspended Solids (TSS), and Fe. Plankton identification using microscope and calculation with cell counting method. The results of analysis of plankton in intensive brackishwater pond waters are obtained as much as 23 genera consisting of 16 genera of phytoplankton were included into three classes, namely Bacillariophyceae as much as 5 genera, Cyanophyceae 3 genera, Dinophyceae and Chlorophyceae, each of the four genera, whereas zooplankton consisting of 7 genera are included into two classes, namely Crustaceae 6 genera and Rotatoria 1 genus. In traditional brackishwater pond earned as much as 13 genera consisting of 8 genera of phytoplankton were included into Bacillariophyceae 5 genera, Cyanophyceae 2 genera, and Dinophyceae 3 genera, whereas zooplankton consisting of three genera are included into class Crustaceae 2 genera and Rotatoria 1 genus. Plankton abundance in intensive brackishwater pond ranges 702 - 4269 ind./L, diversity index of 0.26 -2.38, uniformity index of 0.10 - 1.5, and dominance index of 0.02 - 0.68. In traditional brackishwater pond have an abundance of plankton range 134 - 776 ind./L, diversity index of 0.10 - 1.97, uniformity index of 0.08 - 1.0, and dominance index of 0.01 - 0.75. Traditional and intensive brackishwater pond waters condition still within the limits that can be tolerated by the culture organism. Based on the index value of biological, diversity of genus in the intensive brackishwater pond is relatively higher than traditional brackishwater pond and the community stability moderate, whereas traditional brackishwater pond unstable. On average, the uniformity of the genus in both  brackishwater ponds are relatively evenly and genus of plankton to dominate the others genus.

Abstract

Iron (Fe) and Zinc (Zn) play important role in health both of live stock and human. Fe and Zn in organic form were claimed increasing their viabilities. They bind to certain amino acid formed as a product of microbial metabolism. The Amount Fe and Zn absorbed may indicated the Fe and Zn organic produced. The aim of the study is to determine the absorption of microelement of Fe and Zn by local isolates of Saccharomyces cerevisiae to produce Fe and Zn in organic forms. S. cerevisae BCC F0205, BCC F0206, and BCC F0214 were treated with Fe or Zn 10 ppm to obtain S. cerevisae which has the highest of total concentration of Fe and Zn. Selected isolate was then treated with Fe or Zn respectively 2.5, 5, 10 ppm and their combination. Fe and Zn absorbed by isolates were measured by Atomic Absorption Spectrophotometer (AAS). The results show that  S. cerevisae BCC F0205, BCC F0206, and BCC F0214 treated with 10 ppm Fe or Zn contained total concentration of Fe respectively 1.57, 3.07, 2.24 ppm  and total concentration of Zn respectively 2.34, 3.20, 3.13 ppm. Then, S. cerevisae BCC F0206 treated with 2.5, 5, 10 ppm Fe or Zn, absorbed Fe 1.45, 0.50, 0.94 ppm and Zn 0.73, 0.38, 0.53 ppm respectively. Furthermore, combination of Fe and Zn (2.5:2.5, 5:5, 10:10 ppm) produce absorption of Fe 3.10, 2.13, 3.67 ppm and Zn 0.11, 0.10, 0.28 ppm per gram S. cerevisae BCC F0206. Percentages of absorption by S. cerevisae are up to 100% for Fe and up to 47.20% for Zn. In conclusion, this study indicated that S. cerevisae BCC F0206 absorb Fe and Zn higher than BCC F0205 and BCC F0214 and there are antagonistic interactions found between Fe and Zn in this research.
