**5.5 Differences in classification of activities between Indonesian business field standard code and the classification in the guidelines**

The difference in the classification of activities stated in the guidelines with the classification of activities in the guidelines for the preparation of RDTR and PZ issued by the Ministry of Agrarian Affairs and Spatial Planning (ATR) and the Indonesian Business Field Standard Code (KBLI) [10] issued by BPS, often raises doubts for planners. This problem will continue to be dynamic because BPS determines the KBLI and will continue to develop. The code from this KBLI will be used and listed in the Trading Business License (SIUP), Company Registration Certificate (TDP), and investment permits issued by a notary and affect business activities for investment activities. Therefore, it will be used as a basis for investment, including the application for permits related to spatial planning.
