Salah satunya adalah bisnis berbasis teknologi digital dalam bidang keuangan atau Financial Technology (Fintech). OVO merupakan Fintech yang bergerak di sektor dompet digital (E-wallet). Dengan banyaknya pengguna OVO, maka kualitas sistem dan kepuasan pengguna harus sangat diperhatikan oleh OVO sendiri agar pengguna dapat merasakan kepuasan setiap menggunakan layanan dari OVO. Data yang digunakan dalam penelitian ini adalah data primer yang diperoleh dari kuesioner yang dibagikan kepada mahasiswa perguruan tinggi teknologi pengguna OVO dengan minimal 58 responden dari 52 responden berdasarkan referensi Statistical Power dari Cohen dengan jumlah 2 arah panah, significance level 5% dan minimum R2 0,25. Skala pengukuran yang digunakan adalah skala linier dengan skala 4. Artinya, 4 = sangat setuju, 3 = setuju, 2 = tidak setuju, dan 1 = sangat tidak setuju. Data responden dianalisis menggunakan metode SEM-PLS. Kemudian dilakukan tahap pengujian validitas dan reliabilitas dengan indicator reliability, internal consistency reliability, convergen validity, dan discriminan validity. Pada tahap pengujian validitas dan reliabilitas terdapat indikator yang tidak valid atau reliabel yaitu pada indikator X1.6. Lalu dilakukan analisis multivariate antar konstruk dengan menggunakan pengujian coefficients of determinaton (R2), pengujian ukuran efek (f2), dan uji hipotesis. Pada analisis ini dilakukan dua kali iterasi dimana pada iterasi pertama pada tahap uji hipotesis, hanya hipotesis 2 yang diterima sedangkan hipotesis 1 ditolak. Namun, pada iterasi kedua yang dilakukan dengan menghapus indikator X1.6, hipotesis 1 dan hipotesis 2 diterima.Kata kunci: E-Wallet, Kualitas Sistem, Kepuasan Pelanggan, OVO, SEM-PLSABSTRACTTechnology has developed rapidly to encourage competition in the business world.
