The regulation on MSMEs in Indonesia is not yet harmonious and harmonious, due to the emergence of new terms in the business sector such as ultra-micro enterprises and people's business credit, all of which are included in the business sector group. The grouping of MSMEs and large businesses as regulated in the Law on MSMEs has not yet fully integrated the various terms and their regulations. The regulation of business fields that are grouped outside the MSMES has its terms so that there is disharmony in the regulation of MSMEs in Indonesia. The emergence of a stimulus due to the covid-19 pandemic from the government to overcome the downturn of MSMEs has not yet touched other business fields. This stimulus Law number 11 of 2020 concerning Job Creation has not touched the harmonization of regulations regarding MSMEs. Harmonization of MSME regulations is important, besides the criteria, so that the focus of MSME development and terms that appear that fall into the category of MSMEs can be regulated, transparently, and can be accounted for. The single database mandated by the Job Creation Law is the main factor in harmonizing MSME regulations.
