The Regional Spatial Planning Policy (RTRW) is a legal umbrella in regional development, but the policy is sometimes not based on actual conditions on the ground, resulting in an out-of-sync with the direction of spatial use. As a result, there is a gap between the spatial planning policy and its realization. This is what happened to the Garut Regency RTRW policy related to the Industrial Designated Area. This study aims to determine the suitability and gap between the Garut Regency RTRW policy and the realization, especially regarding the industrial designation area for the Sukastret leather tanning industry, Garut Kota District. The policy research method (policy research) is used in this study by synchronizing the RTRW policy with conditions in the field and with related laws and regulations combined with an Importance Performance Analysis (IPA) approach to determine the level of a gap between policy and realization. Based on the analysis results, the direction of the spatial pattern of the RTRW related to the industrial designation area in Garut Kota District has not been based on regulations, laws, and conditions in the field, so that there is asynchrony in planning. Likewise, with the direction of the spatial planning policy with actual conditions in the field, there is a gap of 42 percent. For the spatial planning policy to be effective, the existing RTRW Regional Regulation needs to be reviewed (PK) for further revision based on the relevant laws and regulations and actual conditions in the field.
