Abstract

This study aimed to identify public awareness regarding the halal status of cough medicines containing alcohol in Indonesia. Although Indonesia is the country with the largest Muslim population, many medicines in Indonesia still contain substances prohibited by Islam, such as alcohol. This research employs a qualitative approach with a literature review to explore the community’s understanding and behavior toward halal-certified medicines. The findings revealed that public awareness regarding the halal status of cough medicines is relatively low. Many respondents did not consistently check for halal logos or ingredients on medicine packaging. Additionally, it is difficult to obtain clear and reliable information about the halal status of these medicines. The study concluded that increased educational and social efforts are necessary to enhance public knowledge and prioritization of halal medicines. Ensuring accessible information on halal certification is crucial for promoting the consumption of halal products, particularly in the health sector.

Abstract

The development of edible films using natural polysaccharides presents a sustainable alternative to synthetic packaging materials. This study aimed to enhance the barrier properties of edible films composed of carboxymethyl cellulose (CMC), konjac glucomannan (KGM), and κ-carrageenan (κCarr) by incorporating stearic acid (SA). Films were prepared by blending the biopolymers with SA at varying concentrations (0.1–0.5% w/w) and characterized for their structural, physical, and mechanical properties. Fourier-transform infrared (FTIR) spectroscopy confirmed molecular interactions between SA and the polysaccharide matrix, evidenced by reduced O–H absorption bands and intensified –CH₂– peaks. SA incorporation increased film thickness and moisture content but reduced tensile strength, elongation at break, solubility, and water vapor permeability (WVP). Although the WVP of SA-modified films did not meet the Japanese Industrial Standard at the tested concentrations, the observed trend suggests that higher SA levels could further improve barrier performance. The optimal formulation (0.5% SA) demonstrated enhanced hydrophobicity, acceptable water activity, and moderate tensile strength and opacity. These findings indicate that stearic acid can effectively modify the functional properties of polysaccharide-based edible films, advancing their potential as eco-friendly food packaging materials. Further optimization of SA concentration is recommended to achieve industrial moisture barrier standards.
