According to Zaini, the environmental quality index in the good category shows that the implementation of development has been accompanied by efforts to manage the environment. He said that IKLH was used as the basis for the preparation of the Regional Medium-Term Development Plan (RPJMD) which was related to environmental protection and management.

The air quality index is calculated based on sulfur dioxide (SO2) and nitrogen dioxide (NO2) parameters and the land cover quality index is calculated based on the area of forest cover, non-forest vegetation cover area, green open space, biodiversity park area, and area of forest and land rehabilitation coverage.
