Abstract

Sunflowers have excellent prospects for future development in Indonesia. This commodity offers a variety of uses, from food and medicine to industrial use and even as a beauty product. Currently, development is focused on marginal land, particularly sandy soil. However, such land is known to have various limitations, necessitating innovations to enable its use as cultivation. One such approach is the application of fertilization technology using maggot compost and chicken manure. The purpose of this study was to evaluate the effectiveness of maggot compost and chicken manure on sunflowers in sandy soil. This study was conducted in Pasir Putih, Padang City, from June to September 2025. The design used in this study was a randomized block design with two factors and three replications. The first factor was the dose of maggot compost and the second was the dose of chicken manure. The results showed that the application of chicken manure and maggot compost at various doses resulted in increased growth and yield of sunflowers in sandy soil with each dose increase. Maggot compost at a dose of 20 g/plant and chicken manure at a dose of 30 g/plant had an interaction on plant height. Meanwhile, at a dose of 20 g/plant of chicken manure fertilizer and 15 g/plant of maggot compost, there was an interaction on the number of sunflower seeds.

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.
