Abstract

Pengabdian Masyarakat ini mengangkat isu kurangnya kesadaran dan pengetahuan masyarakat tentang bahaya sampah plastik serta rendahnya pemahaman masyarakat mengenai dampak sampah plastik di Pantai Mertasari, Sanur bagi ekosistem pantai dan sekitar. Meningkatnya kesadaran masyarakat tentang pentingnya menjaga kebersihan ekosistem laut melalui metode sosialisasi secara digital dan pembuatan papan infografis dalam menjelaskan waktu degradasi plastik adalah tujuan dari pengabdian ini. Hasil pengabdian ini merefleksikan bahwa kesadaran dari masyarakat sudah mulai meningkat dengan berkurangnya sampah plastik setiap minggu menjadi 21,6 kg dari 50 kg sampah plastik, dan berdasarkan hasil survei sosialisasi digital masyarakat yang menunjukan 93,33% memahami dampak sampah plastik terhadap lingkungan.

Abstract

Product packaging not only serves as protection but also functions as a strategic visual element that shapes consumer perception at the point of sale. With the advancement of neuroscience-based marketing, neuromarketing has emerged as a promising approach to investigate brain responses to visual stimuli. This study aims to analyze alpha wave activity in response to product packaging images categorized as attractive and unattractive. A total of 25 participants were involved, with visual stimuli selected based on a prior survey of 60 respondents. Brain activity was recorded using EEG from channels O1 and O2 and analyzed using the Power Spectral Density (PSD) method. The results indicate that attractive packaging elicited higher alpha wave activity compared to unattractive packaging and baseline, suggesting increased visual attention. Furthermore, PSD features were classified using three machine learning algorithms: Random Forest, Support Vector Machine, and K-Nearest Neighbors. Among them, Random Forest achieved the highest test accuracy at 78%. This study contributes to the objective evaluation of product packaging design through brain signal analysis and supports the development of data-driven marketing strategies.
