Compatibility of Local Spatial Planning Based on Traditional Rules in Kampung Naga with the Formal Spatial Planning in Indonesia

People, in general, have knowledge derived from their experience in adapting to the natural environment, which is known as Indigenous knowledge or local wisdom.This research explains the internalization of local wisdom values of spatial planning in Kampung Naga by employing a mixed method of qualitative and quantitative approaches.To identify the plausibly and reasonably aspects, an analysis of 16 variables related to norms and planning standards was conducted, meanwhile, to explore the procedures for spatial planning, interviews were carried out with key respondents and local communities.Data collection is done through interviews and questionnaires with 220 respondents.This study found that customary spatial planning resulted in strict protection of protected forests and areas.The values of local spatial placement can be explained plausibly and reasonably, which can be seen in 93.75% of the 16 variables of norms and planning standards and 85.71% of the technical settlements analyzed agreeing with the results.The results also show that 84.9% of protection is carried out internally, not through formal policy intervention.The defense against space changes is carried out by custom (90.8%), protection of space is managed by local institutions (98.3%), and supervision is conducted by local leaders and communities (95.8%).This study suggests that spatial planning should consider the values of local wisdom and seek to replicate them in other places.In addition, the results of this study complement and correct the theory and practice of communicative planning.
