Abstract

Abstract: Fashion consumption behavior among adolescents tends to increase along with developments in fashion trends and the influence of the social environment. This condition indicates that consumption decisions are not only based on needs but are also influenced by lifestyle and friendship groups. This study aims to determine the influence of hedonistic lifestyle and peer conformity on fashion consumption behavior of students at SMA Negeri 3 Medan, both partially and simultaneously. This study used a quantitative approach with a causal associative method. The study population was 288 eleventh-grade students at SMA Negeri 3 Medan taking Economics. The study sample of 167 students was determined using stratified random sampling. Data collection was carried out through questionnaires. Data analysis used multiple linear regression, t-tests, F-tests, and coefficients of determination using SPSS. The results of the study indicate that a hedonistic lifestyle and peer conformity have a positive and significant influence on students' fashion consumption behavior, both partially and simultaneously. The coefficient of determination (R Square) of 0.547 indicates that 54.7% of the variation in students' fashion consumption behavior can be explained by these two variables, while 45.3% is influenced by other factors outside the study. Based on the results of the study, it is necessary to improve financial literacy and understanding of rational consumption so that students can make wiser consumption decisions. Keywords: Hedonistic Lifestyle, Peer Conformity, Fashion Consumption Behavior.   Abstrak: Perilaku konsumsi fashion di kalangan remaja cenderung meningkat seiring perkembangan tren fashion dan pengaruh lingkungan sosial.

Abstract

The traditional herbal medicine (jamu) business group in Medan Krio Village faces systemic challenges of low productivity due to manual processing and a lack of basic financial bookkeeping knowledge. This community service program aims to accelerate micro-enterprise productivity and efficiency through integrated operational and bookkeeping strategies. Implementation methods included situation analysis, focus group discussions, practical training and handover of appropriate technology (TTG) tools, alongside bookkeeping and business management training. Implemented solutions consisted of two wet jamu grinding units (20–30 kg/hour capacity), an 80-cm diameter cauldron, a 50-liter storage container, and a financial ledger. Results showed a 60–70% leap in operational efficiency (reducing time from 6–8 hours to 2–3 hours) and a 100% increase in daily output capacity (reaching 10–20 liters per batch). Partners' managerial literacy surged by 85–90% in preparing independent income statements separate from household finances. The synergy of production mechanization and managerial literacy successfully revolutionized the traditional jamu business ecosystem into an efficient, sustainable micro-enterprise.
