Background and Objectives: The environmental permit from the construction of the TanjungJati B 5-6 steam power plant has consequences for environmental responsibility, in the form of environmental monitoring activities. This research is a monitoring activity on aspects of marine aquatic biology and avifauna status, as a biocontrol of ecological balance. Materials and Methods: The research was conducted by laboratory experimental methods by calculating diversity index, uniformity index, and dominance index in plankton, benthos, and nekton, while avifauna analysis was carried out based on the results of inventory and observations of their encounters at the research location. Results: The status of the water in the study site is included in the medium polluted category. The status of the water in the study site is included in the medium polluted category. The results of the evaluation of diversity index parameters and the plankton-benthos dominance index showed a positive tendency, while the dominance index was negative. The nekton evaluation trends for all negative parameters. Status of the frequency of encounters for Ardea alba, Egretta garzetta, and Ibis bubulcus with a negative tendency. The avifauna is a type that is protected by the Government of the Republic of Indonesia. Conclusion: Action is needed to maintain the evaluation trend of modeling positive trends in all parameters so that the ecological balance in locations around the Tanjung Jati B steam power plant remains good.
