This thesis is entitled "Legal protection of Lake Poso from damage caused by PT. Poso
Energy's dredging activities for hydropower in the town of Tentena, Poso Regency,
Central Sulawesi". The lake is a freshwater ecosystem that stores various natural
resources, and is spread over various islands in Indonesia. Lakes are managed and
utilized, among others, as a source of water for daily needs, fishing activities, energy
sources, tourism activities and as a habitat for biodiversity. It is known that Lake Poso is
the third largest lake in Indonesia which was formed due to geological activities, namely
tectonic and has become a habitat for various types of fish, including endemic fish. To
increase the availability of water for hydropower, dredging activities are carried out,
especially in the Poso river area. Regarding dredging, it has been regulated in
Attachment 1 to Regulation of the Minister of Environment and Forestry Number 4 of
2021 concerning List of businesses and/or activities that are required to have an
Environmental Impact Analysis, Environmental Management Efforts, and
Environmental Monitoring Efforts or a Statement of Ability to Manage and Utilize
Environment. Dredging activities have positive and negative sides for Lake Poso. For
this reason, legal instruments are needed to provide legal protection for Lake Poso to
avoid damage.
