The conclusion of this study is that there is a relationship between the age and depth of diving toward the incidence of ear barotrauma in traditional diver fishermen, while the factors of working period, dive duration, frequency of diving, rest duration, and diving procedures are not related to the occurrence of ear barotrauma in traditional diver fishermen in Bulawa Sub-district Bone BolangoRegency.
