3. Title “Freshwater Quality Monitoring at University of Indonesia”

4. Objective To investigate the freshwater quality of several lakes at University of Indonesia

5. Description of Activity 1. Freshwater Quantitative Measurement Students will take the quantitative measurement of the lake, measurements such as; dissolved oxygen, pH, temperature, transparency etc. These measurements will provide the basis for discussion to analyse the condition of the ecosystem 2. Freshwater Invertebrate Biological Indicator Students will learn how to identify several freshwater invertebrate biological indicators in the lake. These animals will be the key for students to know the water quality of the lake. 3. Plankton collection Students will collect samples of plankton using plankton net. These planktons with its particular characteristics will help students to determine the water quality of the lake.

6. Background In this activity we will investigate how much pollution has affected the condition of a named freshwater ecosystem (e.g. lake) using an ecological approach. Through this simple method of investigation it is hoped to give a hands on experience of learning for us, and the results will be useful for them and also for whom it may concern and also for further studies. University of Indonesia has 5 lakes, these lakes act as a water reservoir for the town of Depok. The lakes get their waters from surrounding small rivers and drains. Consequently, these lakes are prone to water pollution. This location will provide the best condition and also experience to us to do freshwater ecosystem studies. Write about Study Area.
