ABSTRACTImplementing entrepreneurship as part of the Merdeka Curriculum is considered suboptimal due to the numerous challenges schools face. This is consistent with the survey results among chemistry educators in the Singkawang, which showed that while most have implemented entrepreneurship in their teaching, it has not yet incorporated local wisdom and has not been included in their teaching tools. The purpose of this community service program (PKM) is to enhance educators' ability to develop entrepreneurship-based learning that incorporates local wisdom and to describe educators' responses to the training activities conducted. The method used in this PKM is a training method for 24 chemistry educators in Singkawang, consisting of three stages: preparation, implementation, and evaluation. The results of the PKM activities showed increased knowledge and helped Singkawang's chemistry educators integrate these two concepts into their teaching.Keywords: Learning Development, Entreprenuership, Local Wisdom ABSTRAKPelaksanaan kewirausahaan sebagai implementasi kurikulum merdeka dirasa belum optimal dikarenakan terdapat banyak kendala yang harus dihadapi oleh sekolah.
