In order to preserve and support local wisdom, Community Development PT. Kukuh Mandiri Lestari also supports Istifalan Activities in order to welcome the arrival of the Holy Month of Ramadan at several Ta'lim Assemblies located in Muara Village, Lemo Village, Tanjung Burung Village, and Tanjung Pasir Village, Teluknaga District and Dadap Village, East Kosambi Village, Kosambi District Kosambi Village.

The activity was filled with the appearance of speeches, deposits of memorization of the holy verses of the Qur'an, as well as tausiyah from children who for approximately 1 year had studied in the assembly. This Istifalan activity is also a closing of learning activities in each Ta'lim Assembly located in Teluknaga District and Kosambi District, as well as to train the courage of the next generation of the nation to dare to appear in public.

In addition, parents also participate in supporting Istifalan Activities by giving 'saweran' to their children when they perform on stage. On this occasion, the PIK 2 Community Development Team also gave a number of Qurans to children through the Ta'lim Assembly so that they would be more enthusiastic in learning and worshipping during the Holy Month of Ramadan.
