Penelitian ini menggunakan metode penelitian kualitatif dengan pendekatan deskriptif, sedangkan pengumpulan data diperoleh dengan observasi, wawancara, dan dokumentasi yang dilakukan di pondok pesantren Al-Ishlah. Dalam penelitian penulis menggunakan Teori Konstruksi Sosial Berger dan Luckmann dengan menggunakan 3 konsep dialektis pembentukan makna radikalisme bagi para santri.
Berdasarkan penelitian yang dilakukan, ditemukan bahwa pembentukan makna radikalisme pada santri didasari pada pengetahuan subjektif mereka tentang radikalisme yang didapat dari cadangan pengetahuan santri yang didapatkan dari banyak hal dalam kehidupan santri dimana santri diberi pengetahuan mengenai ajaran agama sesuai Ahlussunsah Waljamaah. Sehingga santri dapat mentransfer kembali ilmu mereka yang di dapat dari pondok pesantren kepada masyarakat luas. Terdapat 4 peranan pondok pesantren Al-Ishlah dalam mencegah muncul dan maraknya aliran keagamaan yang menyimpang. Pertama, strategi pembelajarn pesantren yang moderat. Kedua, kyai sebagai teladan santri. Ketiga, manjemen kurikulum pondok pesantren. Keempat, penguatan aturan pondok pesantren.

FKUB (Forum Kerukunan antar Umat Beragama) menjadi wadah yang dapat memfasilitasi komunikasi antar umat beragama agat tidak ada lagi dominasi agama tertentu.
