Abstract

The Community Service Program (PKM) themed “Gen Z and PayLater: Digital Financial Literacy to Prevent Financial Risk” was conducted to improve digital financial literacy and raise awareness of PayLater risks among Generation Z in Pontianak City. This activity was motivated by the rapid growth of financial technology, especially Buy Now Pay Later (BNPL), which is widely used but often misunderstood as non-debt.The methods included presentations, interactive discussions, and evaluation using pre-test, post-test, and questionnaires completed by 80 participants. The evaluation focused on four variables: digital financial literacy, socialization/education, PayLater usage behavior, and financial risk. The results showed that digital financial literacy was categorized as Good (4.38), socialization/education as Very Good (4.62), PayLater usage behavior as Good (4.35), and financial risk awareness as Very Good (4.58). Regression analysis indicated that digital financial literacy and socialization significantly influenced PayLater usage behavior, while behavior had the strongest effect on financial risk. In conclusion, this PKM activity effectively improved participants’ financial understanding, encouraged responsible PayLater usage, and increased awareness of financial risks, contributing to healthier financial behavior among Generation Z in the digital era.

Abstract

This study explores the potential of pineapple leaf fiber (PALF) from the Queen variety as a sustainable reinforcement material for green composites and textiles, focusing on the effects of mechanical retting. The research addresses critical barriers to industrial adoption, such as fiber-quality variability and hydrophilicity, while highlighting an innovative waterless extraction method that reduces environmental impact compared with conventional processes. A quantitative experimental approach was employed to comprehensively characterize PALF, incorporating standardized tensile testing to measure mechanical properties and microscopic analyses with a Scanning Electron Microscope (SEM) to observe fiber morphology. Findings demonstrate that mechanical retting significantly improves PALF’s tensile strength (23.2 g/tex) and fineness (33.7 dtex). Microscopic analysis reveals a uniform, compact fiber structure that underpins the material's enhanced mechanical performance. PALF emerges as a viable, eco-friendly alternative to synthetic fibers. The waterless mechanical retting process is an effective method for producing high-quality reinforcement fibers, offering practical guidance for industries. This approach contributes significantly to agricultural waste reduction and advances circular economy principles in sustainable materials development.
