Climate change causing a shift in the dry and rainy seasons, and impacts the availability of water that is getting less. Its change people activity used the river directly thus increasing pollution. As a river management effort, it is necessary to carry out periodic monitoring by public. This study aims to determine the biological water quality of the Gajah Wong river segment Yogyakarta city, Indonesia based on biomonitoring with family biotic index (FBI). The data used are primary data form field data collection. The data collection method used is biomonitoring. The observed parameters were the overall diversity of benthic macroinvertebrates, Water quality follow analysis with family biotic index (FBI). The results showed the stations Gajah Wong 2 (GW2), GW3, and GW8 were of the water quality good, whereas the stations GW1, GW7, and GW6 were of the quality fair fairly. Then the stations GW5 and GW10 were of the water quality fairly poor, the stations GW9 poor very, and finally, station GW4 were of the water quality very poor, this can be seen in the result of the collected organism data, namely the majority is Tubificidae group found 65.30%.
