Penelitian ini bertujuan untuk menganalisis kelayakan Lembar Kerja Siswa (LKS) model Problem Based Learning (PBL) Berbasis STEM (Science, Technology, Engineering, and Mathematics) untuk membangun kreativitas siswa kelas X dalam pembuatan model bentuk molekul. Metode penelitian yang digunakan yaitu penelitian deskriptif kualitataif dan dalam pembuatan LKS menggunakan desain penelitian dan pengembangan (Research and Development). Penelitian ini terdiri dari tiga tahap yaitu tahap persiapan, pelaksanaan dan pelaporan. Instrumen yang digunakan dibagi menjadi 3 bagian yaitu intrumen uji kelayakan internal, instrumen uji kelayakan eksternal dan instrumen penilaian kelayakan berdasarkan tinjauan TCOF. Partisipan dalam penelitian ini sebanyak 2 orang dosen pendidikan kimia, 1 orang guru kimia di salah satu SMA di Tasikmalaya, 3 orang siswa SMA dan 1 orang observer TCOF. Penelitian ini dilakukan ketika keadaaan sedang pandemi, sehingga uji coba dilakukan secara terbatas menggunakan media aplikasi zoom dan partisipan yaitu siswa dipilih berdasarkan jarak tempat tinggal yang berdekatan sehingga masih bisa untuk membuat kelompok kerja dan melaksakan penelitian dengan memperhatikan protokol kesehatan. Hasil penilaian uji kelayakan internal memperoleh persentase 95,64% (Sangan Baik), hasil penilaian uji kelayakan eksternal memperoleh persentase 94.71% (Sangat Baik), dan hasil penilaian kelayakan LKS berdasarkan tinjauan TCOF memperoleh nilai sebesar 2.48 (Tinggi). Berdasarkan hasil penilaian, maka LKS model PBL berbasis STEM dalam pembuatan model bentuk molekul layak digunakan untuk membangun kreativitas siswa. This research aims to analyze the feasibility of student worksheets (LKS) problem based learning motedos, STEM based to improve the creativity of class X student in making molecular shape models. The research method used is descriptive qualitative research and in making LKS using research and development designs. This research consists of three stagessteps: preparation, implementation and reporting. The instrumen used was divided into 3 part, namely the internal feasibility test assesement itnstrument, the external feasibility test instrument and the feasibility assesment instrument based on the TCOF review. Participants in this study here 2 chemistry lectures, 1 chemistry teacher in one of the high schools in Tasikmalaya, 3 high school student and 1 TCOF observer. This research was carried out when it was pandemic, so trials were carried out in a limited manner, so the trials were carried out in a limited manner using the media aplication of the zoom and participants namely choosen based on the distance at the adjacent living spaces so the they could still create working groups and carry out research by paying attention to health protocols. Internal feasibility test result obtained a percentage of 95.64% (Very good) the results of the assesment of external feasibility test obtained a percentage of 94.71% (Very good) and the results of the assesment of the feasibility of LKS based on TCOF review obtained a value of 2.48 (higt). Based on the results of the assessment, the STEM-based PBL LKS model in making molecular shaped models is appropriate to be used to increase student creativity.
