The research shows that the reason students in the Special Region of Yogyakarta tend to be more consumptive when using TikTok Shop PayLater is due to easy access, the availability of various payment terms, peer and environmental influence, the lure of discounts, as well as social pressure (FOMO) and a hedonistic lifestyle. From the perspective of Islamic legal sociology, this practice indicates a shift in consumption patterns from actual needs (hajat) to symbolic and emotional consumption for social recognition. This suggests a weak internalization of the value of hifz al-mal (protection of wealth) and a tendency toward israf and tabzir behavior, even though formally, the transaction contract meets the requirements of a valid contract.340.115 Sosiologi Hukum2026-07-16UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SYARI’AH DAN HUKUMThesis
