ABSTRACT The research was conducted with the aim of improving collaboration skills in 5th grade elementary school students using the Problem Based Learning (PBL) instructional model. The study took place at SDN Tingkir Tengah 02 Salatiga in the first semester of the 2023/2024 academic year, with a total of 28 students. This research is a Classroom Action Research with non-test data collection techniques, and quantitative data analysis. The instrument used was an observation sheet for collaboration skills. The research consisted of two cycles. The results of the research showed that the Problem Based Learning instructional model can enhance collaboration skills. This was evidenced by the pre-cycle data, where only 32.14% of the fifth-grade students exhibited good collaboration skills, while 67.86% were still lacking in collaboration skills. In the first cycle, there was an increase to 53.57% of students with good collaboration skills, while 46.43% of students still had insufficient collaboration skills. In the second cycle, there was a further improvement, with 82.57% of students demonstrating good collaboration skills, and 17.43% of students still lacking in collaboration skills. This improvement was evident in changes in student behavior, as students in the pre-cycle appeared to prefer working individually, but after the implementation of this model, students were very enthusiastic about collaboration.   Keywords: Collaboration Skills, Problem Based Learning (PBL) ABSTRAK Penelitian dilaksanakan dengan tujuan untuk meningkatkan collaboration skils pada siswa kelas 5 Sekolah Dasar dengan menggunakan model pembelajaran Problem Based Learning (PBL).
