This research was carried out in the Cirahab water source area located in Curuggoong Village, Padarincang District, Serang-Banten Regency. This research aims to determine the diversity of insects as an indicator of the cleanliness of the Cirahab source water which is widely used by local communities for bathing, washing and other needs. which of course can affect the existence of these freshwater insects. Hence, the insect samples collected use various equipment, such as buckets, trays, insect tissue, which are taken from the Cirahab water source. The calculation method used is by referring to the formula from Shannon Wiener. The results of calculating the diversity index value obtained a result of 2.63566, this result shows a "Medium" result. Apart from that, there are measurements of water cleanliness, including temperature with a value of 24 mg/l, TDS 45 mg/l, BOD 0.93 mg/l, COD 90,321 mg/l, DO 50 mg/l and water flow of 0.20 m/s.
