Program Magang dan Studi Independen Bersertifikat (MSIB) menjadi salah satu program Merdeka Belajar-Kampus Merdeka (MBKM) yang paling diminati mahasiswa karena dapat membekali keterampilan nyata dunia kerja dengan konversi maksimal 20 SKS. Selain memberikan manfaat bagi mahasiswa, program tersebut juga memberikan tantangan baru bagi mereka. Mahasiswa dinilai membutuhkan kemampuan adaptabilitas karier agar dapat mengoptimalkan performanya dalam program tersebut. Penelitian ini bertujuan untuk mengetahui peran core self-evaluation dan kepribadian proaktif dalam memediasi hubungan dukungan sosial dengan adaptabilitas karier pada mahasiswa yang sedang menjalani program MSIB. Partisipan penelitian ini terdiri atas 175 orang mahasiswa Indonesia yang sedang menjalani program MSIB. Alat ukur yang digunakan dalam penelitian ini adalah Career Adapt-Abilities Sca le International Form (CAAS-IF), Child and Adolescent Social Support Scale (CASSS), Core Self-Evaluation Scale (CSES), dan Proactive Personality Scale (PPS), yang sudah diadaptasi dan diterjemahkan ke dalam Bahasa Indonesia serta dimodifikasi sesuai dengan konteks penelitian. Hasil penelitian menunjukkan bahwa core self-evaluation dan kepribadian proaktif memediasi secara parsial hubungan antara dukungan sosial dan adaptabilitas karier mahasiswa yang sedang menjalani program MSIB. Semakin tinggi dukungan sosial yang diperoleh mahasiswa, maka akan semakin meningkatkan core self-evaluation dan kepribadian proaktifnya, yang pada akhirnya akan meningkatkan kemampuan adaptabilitas kariernya. Di sisi lain, dukungan sosial sendiri dapat memengaruhi adaptabilitas karier secara langsung, yaitu semakin tinggi dukungan sosial yang diperoleh mahasiswa, maka akan semakin meningkatkan kemampuan adaptabilitas kariernya.
