This study aims to determine the impact of the traditional practice of "sesan" on the indigenous people of Lampung "Pepadun" Negara Aji Baru Lampung, which is intended to inculcate social values in "sharia" or Islamic law. A qualitative research design was used to guide the research. The main data sources came from interviews conducted with "Penyimbang Adat" ("Penyimbang" custom), religious leaders, and the indigenous people of Lampung "Pepadun" Bumi Aji. The research findings reveal that the traditional practice of "sesan" is a form of local wisdom of the indigenous people of Lampung "Pepadun," which must be implemented in the marriage contract. Social values in "sharia" provide an understanding of the position of "sesan" property in marriage seen from the wisdom and benefits it obtains. "Sesan" treasure aims to glorify a wife like a queen in a household who needs various household facilities. This is intended to reduce the fear of getting married because they do not have the facilities for their household needs. "Sesan" property is not allowed if in practice it conflicts with social values in the Lampung "Pepadun" custom which places the male party as an object imposed by self-interest, not based on mutual help. The novelty of this study states that the theoretical concepts used have succeeded in finding the understanding gaps that occur in the indigenous people of Lampung "Pepadun." The findings also reveal that the inculcation of social values is through mutual cooperation between relatives or because of the services provided by relatives in customary community marriages. It should be understood that the "sesan" custom in marriage is intended to be the basic capital in fostering a household. The traditional practice of "sesan" which raises property issues in indigenous peoples is expected to contribute to the cultivation of Islamic law and social values and local wisdom and become a source of knowledge as a form of self-actualization and alternative moral education.
