Tanah Bumbu Regency is one of the areas in South Kalimantan, Indonesia, which is known
as the "Industrial Regency" because of its diverse industrial activities, especially in the
mining sector, both mineral and coal. This research aims to understand the supervision
carried out by the Environmental Service on the environmental impacts of coal mining
companies and to identify obstacles and solutions that can be implemented in this
supervision in an effort to prevent environmental pollution in Tanah Bumbu Regency. The
type of research carried out is empirical legal research, which focuses on social facts in
the field. This research was conducted by interacting directly with respondents to obtain
primary data, which was then supported by secondary data from various legal sources. The
research results show that the supervision carried out by the Tanah Bumbu Regency
Environmental Service regarding the environmental impacts of coal mining companies is
quite good through direct and indirect supervision. However, this supervision is not yet
optimal because there are several obstacles, such as limited human resources and the
budget allocated by management for environmental management and monitoring. Efforts
to increase supervision need to be made so that the negative impacts of mining activities
can be minimized.
