Abstract

This study aims to develop a mathematical model to analyze the impact of the revitalization program at Koga Market, Bandar Lampung, on traders’ profits by examining the influence of sales volume, marketing costs, staple-goods prices, and infrastructure costs. Using a quantitative survey approach involving 50 randomly selected traders, data were collected through questionnaires, interviews, and documentation, and analyzed using descriptive statistics, classical assumption tests, and multiple linear regression. The results show that staple-goods prices and infrastructure costs have a strong and significant positive effect on traders’ profits, marketing costs also contribute positively, while sales volume shows a negative but insignificant effect. All classical assumptions were met, indicating that the regression model is valid for explaining the profit determinants. The findings confirm that market revitalization has generated measurable economic benefits through improved infrastructure and stable commodity prices, suggesting the need for continued infrastructure enhancement and strengthened marketing strategies to further support traders’ economic sustainability.

Abstract

Banana bud is an underutilized byproduct of the banana plant. Banana bud is rich in fiber and macronutrients that promote health. The potential of banana bud can be optimized by transforming it into convenient ready-to-eat food products. This study was contributed to facilitate the conversion of agricultural waste into nutrient-dense functional foods. This investigation will involve the preparation of flakes using banana bud flour and arrowroot flour as substitutes for wheat flour. Each mixture incorporated banana bud and arrowroot flour at concentrations of 5%, 10%, and 15%. Additionally, the flakes will undergo assessment of their chemical, physical, and sensory characteristics. The incorporation of banana bud and arrowroot flour into the flakes resulted in a considerable increase in total protein and crude fiber values compared to the control sample. The hardness and crunchiness of the flakes varied considerably, although the water absorption capacity rose markedly. The incorporation of banana bud flour resulted in the flakes acquiring a reddish hue. The outcomes of the descriptive sensory evaluation yielded an assessment of color, odor, texture, flavor, aftertaste, and texture after rehydration conducted by the panellists. The study's results indicate that banana plant waste can be utilized to produce nutrient-dense food products favored by panellists.
