Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan menggunakan studi kasus. Data diperoleh melalui wawancara, observasi, dan dokumentasi. Subjek penelitian dipilih menggunakan purposive sampling. Teknik analisis data yang digunakan mengacu pada model Miles dan Huberman, yaitu mereduksi data, menampilkan data, dan menyimpulkan. Hasil penelitian menunjukkan adanya kesamaan metode yang digunakan kedua Ponpes tersebut. Keduanya mengintegrasikan visi, misi, dan program kegiatan ke dalam nilai-nilai pendidikan karakter melalui ko-kurikuler, intrakurikuler, ekstrakurikuler, dan habituasi. Santri mempraktikkan nilai-nilai seperti agama, kesopanan, disiplin, jujur, kerja keras, mandiri, bertanggung jawab, saling membantu, toleran, peduli terhadap lingkungan sosial dalam kehidupan sehari-hari. Kontrol minimum mampu memberi kesempatan bagi Santri untuk menghindari perilaku negatif. Pendidikan karakter yang diprogramkan dan terintegrasi ke semua kegiatan di Ponpes cukup efektif untuk membangun karakter Santri yang membutuhkan kolaborasi intensif antara orang tua dan masyarakat untuk mendidik dan mengontrol Santri ketika mereka berada di luar wilayah Ponpes.
