Design System Analysis of Water Quality Survey Using Macro Benthos Indicator with Biotic Family Index Approach

摘要

Waters are an important part of an ecosystem and have important functions for human life, such as the need for drinking water, household activities, agro-industry, manufacturing and other production activities requiring water so that the aquatic environment needs to be maintained in quality. One of the biological factors from water quality is the life of macro benthos organisms. In some existing studies macro benthos is usually used as a bioindicator of water quality. The presence of a specific macro benthos family or macro benthos organism that has similarities in the aquatic environment signifies the water quality level. Such extreme environmental changes provide a macro benthos life tolerance value called the Biotic Factor Index (BFI). The purpose of this publication is Knowing the relationship between the biotic index and water quality, SQL syntax to calculate the Biotic Index from the input of each sampling point, the design of the system that accommodates each macro benthos findings from each sampling point in a water. The biotic value from spring to autumn is 2.59, 2.68, 3.22, 3.42, all of them is in very good water quality.
