Pada April 2020, diresmikan program kartu prakerja, yaitu pelatihan gratis bersertifikat dan pemberian insentif dalam rangka peningkatan keterampilan. Penelitian ini membahas transformasi pendapatan pekerja melalui program pelatihan prakerja dengan memfokuskan pada dampak penggunaan digital dan karakteristik usia. Ordinary Least Square (OLS) digunakan dalam 3 model untuk melihat dampak umur dan dugaan pola U terbalik pada pendapatan, interaksi variabel pelatihan prakerja dan umur, interaksi variabel pelatihan prakerja dan penggunaan digital yang diolah dari Sakernas Agustus 2022. Hasil analisis menunjukkan bahwa penerima pelatihan program prakerja menerima 2,61% pendapatan yang lebih tinggi dibanding non penerima pelatihan. Sementara, pendapatan pekerja akan meningkat sebesar 2,89% setiap tahunnya sampai pada umur 45, kemudian pertumbuhan pendapatan menurun. Namun, dampak upah dari pelatihan prakerja tidak berbeda secara signifikan berdasarkan usia.
