ABSTRAK
Penelitian ini dilakukan untuk mengetahui ada atau tidaknya efek mediasi kepribadian proaktif dalam pengaruh kecerdasan emosi terhadap efikasi diri keputusan karier siswa Sekolah Menengah Kejuruan (SMK). Siswa SMK diketahui mengalami kesulitan dalam membuat keputusan karier di akhir masa studinya, padahal mereka telah menentukan kejuruan mereka sejak memasuki SMK. Salah satu penyebabnya adalah siswa kurang memiliki efikasi diri keputusan karier. Untuk menanggulangi hal tersebut, efikasi diri keputusan karier siswa perlu ditingkatkan melalui faktor lain yang memengaruhinya, seperti kecerdasan emosi. Kepribadian proaktif dipilih sebagai variabel mediator. Studi kuantitatif ini dilakukan terhadap 833 orang siswa SMK kelas 12 di sembilan sekolah wilayah Depok dan Jakarta Selatan, dengan menggunakan metode non-probability sampling jenis accidental sampling. Alat ukur yang digunakan yaitu Career Decision Self-Efficacy Scale-Short Form (CDSES-SF), Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF), serta Proactive Personality Scale (PPS), dengan masing-masing alat ukur memiliki reliabilitas > 0,7. Analisis mediasi dilakukan menggunakan PROCESS oleh Hayes, dengan hasil kepribadian proaktif mampu memediasi pengaruh kecerdasan emosi terhadap efikasi diri keputusan karier secara partial (ab = 0,10, c' = 0,12, p<0,01). Hasil studi ini dapat digunakan pada program intervensi untuk meningkatkan efikasi diri keputusan karier siswa, dengan memperhatikan faktor kecerdasan emosi dan kepribadian proaktif pada siswa.
