Abstract

The zooplankton ecological index which includes diversity, uniformity and dominance is one approach used to determine the condition of the aquatic environment. This study aims to determine the environmental status of the waters based on zooplankton ecological index which includes diversity, uniformity, and dominance in Doreri Bay water, Manokwari. This study was conducted in September 2020 at two 5- and 10-meter stations depth from the water's surface. Water quality measurements and water sampling were carried out at both stations thrice for 1 week. Water sampling to determine individual zooplankton used a 5 L volume Van Dorn. Temperature, salinity, and pH of the waters were measured successively using a rod-type thermometer with a 50 °C scale, a handheld refractometer RHSN-10ATC, and a pH meter of Orion A215 type. The measurement results obtained the temperature, salinity, and pH values ranging from 29.1 – 29.9 °C with an average of 29.5 °C, 30 – 35 ppt with an average of 33.2 ppt, and 7.9 – 8.3 with an average of 8.1, respectively. The diversity, uniformity, and dominance indexes ranged from 1.5 – 2.2, 0.7 – 1.0, and 0.1 – 0.4, respectively. The ecological status of Doreri Bay waters based on the diversity, uniformity, and dominance indexes show that the components of the food chain are still complete, including the producer and consumer groups and reducers. The effect of liquid waste from land activities around the bay has not disturbed the zooplankton.

Abstract

After knowing how to take and handle plankton water samples and knowing and understanding how to use a microscope, the next problem that arises is how to count or observe and identify plankton water samples with a microscope in the laboratory. Based on this, this community service aims to describe in detail how to identify plankton in the laboratory. The tools and materials used for plankton identification in the laboratory consist of a reversible microscope, preparations, Sedwig rafter cells, coverglass, dropper pipettes, counters, plankton water sample bottles, spray bottles, notebooks or HVS paper, 2B pencils, erasers and tissues. The stages of plankton identification in the laboratory consist of the preparation stage and the implementation stage. The preparation stage consists of preparations outside the laboratory and in the laboratory. Preparations outside the laboratory include plankton water sample bottles, spray bottles, counters, notebooks or HVS paper, 2B pencils, erasers and tissues. The most important preparation outside the laboratory is to prepare plankton identification sheets and plankton identification books. Preparations in the laboratory include a reciprocating microscope, preparations or SRC, dropper pipettes, and coverglass. The implementation stage of plankton identification in the laboratory consists of 18 procedures that must be followed sequentially. Plankton identification includes 18 procedures with a primary focus on sample loading, microscope setup, determination methods, and plankton counts.
