Abstract

This study aims to analyze consumer preferences to the quality of street-vendor coffee in payakumbuh city and identify the factors influencing consumer purchasing decisions. The method used is a quantitative approach. 100 street-vendor coffee consumers selected using purposive sampling method. Data were collected through questionnaires, observations, and documentation, then analyzed using Spearman’s Rank Correlation Analysis. The results showed that the price perception factor has the strongest and most significant relationship with purchasing decisions (rs = 0.727) and followed by product quality (rs = 0.512). These findings suggest that affordability, perceived price fairness, consistent taste, safety, and practical packaging are key determinants shaping consumer preferences and encouraging repeat purchases. The demographic characteristics of respondents dominated by young consumers with low to middle income further emphasize the importance of competitive pricing in this market segment. This findings implicate that street-vendor coffee business operators need to implement competitive pricing strategies while maintaining consistent product quality, particularly in terms of taste, safety, and practical packaging, in order to enhance perceived value and encourage purchases. Local governments should design empowerment programs for street-vendor coffee MSMEs, including food hygiene training, product quality improvement, and market-oriented business management.

Abstract

This study aims to analyze the entrepreneurial behaviors of MSME actors in the cassava processing sector in Padang City and their influence on business performance. A descriptive quantitative approach was employed, with data collected through interviews and a 5-point Likert scale questionnaire distributed to cassava processing entrepreneurs. The results indicate that individual factors such as education, experience, and motivation are categorized as high and positively contribute to entrepreneurial behavior. Environmental factors such as input availability, training, capital assistance, promotion, and the cohesiveness among entrepreneurs also support business performance, although challenges remain in extension services, marketing, and business regulations. Overall, the business performance of cassava processing MSMEs in Padang City is classified as high, as reflected in market expansion, increased income, and competitive advantage. The synergy between strong individual characteristics and optimal environmental support is key to enhancing the competitiveness and sustainability of cassava processing businesses in Padang City.

Abstract

The increasing environmental concerns associated with conventional plastic packaging have accelerated the global pursuit of sustainable alternatives. This review explored the innovative transformation of agricultural waste into eco-friendly food packaging materials, highlighting its potential to address both ecological and economic challenges. Agricultural residues—such as cereal by-products, sugar and starch crop wastes, fruit processing leftovers, and leaf waste—were rich in biopolymers like cellulose, starch, and pectin, making them suitable candidates for biodegradable packaging. Through advancements in green chemistry, biotechnology, and materials science, these wastes are now being repurposed into high-performance, compostable packaging solutions. Relevant literature was selected through a systematic search of peer-reviewed journal articles from databases such as Scopus, ScienceDirect, and Google Scholar, focusing on publications from the last five years that addressed agricultural waste utilization in ecofriendly food packaging. The review synthesizes recent research and technological breakthroughs in this field, showcasing applications ranging from rice husk-based films to cassava starch bioplastics. Furthermore, it examines the environmental benefits of reduced plastic pollution and landfill burden, alongside the economic advantages of waste valorization, rural job creation, and market competitiveness. By turning agricultural residues into valuable resources, this approach supports circular economy principles, enhances food system sustainability, and paves the way for a greener packaging industry.
