This study aims to analyse and criticise the application of sustainable development principles in forest spatial planning. The research method used is normative juridical research, and the approach used is the context and statutory approaches. The study results show that law in the primary sector must refer to sustainable development and people's welfare. Forest destruction cannot be considered a consequence of activities in this sector; it also reflects the failure of spatial planning in an area. The embodiment of spatial planning that can realise environmental preservation must lead to how the law exists in the community. The community around the forest area, as the leading actor, plays a crucial role in controlling and protecting the forest, and their involvement is vital for successful environmental preservation. An extraordinary, measurable, planned, and directed spatial arrangement is urgently and significantly needed. This is done so that the living environment is maintained and planned. Good planning is expected to lead to good spatial use, but this requires consistent management so that environmental sustainability remains aligned with spatial planning scenarios.
