Abstract

Arabica coffee is celebrated for its unique flavor profile, yet enhancing its global market competitiveness requires innovation in post-harvest processing. Fermentation using lactic acid bacteria (LAB) specifically Lactobacillus plantarum and Lactobacillus brevis holds promise for modifying the coffee’s flavor, boosting acidity, and enriching its aroma and flavor complexity. However, the use of this technique in Arabica coffee processing remains limited. This study therefore aims to examine how LAB fermentation and roasting techniques influence the quality of Arabica coffee. The key controlled variables were fermentation duration (0, 12, 48, and 72 hours) and roasting method, which included light roast (160°C), medium roast (180°C), and dark roast (200°C). The experiment followed a Factorial Randomized Complete Block Design (RCBD) with a 4×3 factorial arrangement and three replications, yielding a total of 36 experimental units. Data were analyzed using Analysis of Variance (ANOVA) as part of a quantitative descriptive analysis. Based on the research findings, it can be concluded that fermentation time, roasting technique, and their interaction significantly affect the pH and moisture content of Arabica coffee beans. Meanwhile, roasting technique alone significantly influences caffeine content. The optimal treatment identified in this study was Arabica coffee beans fermented with Lactobacillus plantarum for 24 hours followed by medium roasting (180°C), which yielded a pH of 5.18, moisture content of 3.77%, caffeine content of 1.20%, a cupping score of 78.35, and a chlorogenic acid (CGA) content of 18.16 mg/g of roasted coffee beans.

Abstract

Students at Al Ma’soem Elementary School represent a group vulnerable to hazardous non-food dyes (such as Rhodamine B) due to the high consumption of brightly colored snacks and low food safety literacy. This issue is exacerbated by the lack of knowledge among local producers regarding Food Additive (BTP) regulations. The 'Food Detective' Program aims to enhance students' awareness and motor skills in identifying hazardous substances independently to foster more selective consumption behavior. Implementation utilizes experiential learning through visual socialization, simple science experiments (rapid tests) using natural indicators like turmeric, and evaluations via pre-tests and post-tests. Mentorship was also provided to canteen operators to transition to natural dyes. This initiative significantly improved student literacy, as evidenced by post-activity evaluation scores. Managerially, the program successfully established 'Food Detective' cadres as a sustainable internal school monitoring system. Furthermore, collaboration with canteen vendors in using natural alternatives (such as suji leaves or beets) has created a healthy canteen ecosystem.

Abstract

The potential of Lini S Arabica coffee, known for its sweet base flavor and floral nuances, is often not fully realized due to conventional post-harvest processing. This study aimed to analyze the influence of controlled fermentation using Lactobacillus plantarum combined with a medium roast profile on the sensory quality of Lini S variety brewed coffee. The research employed an experimental design with two treatment groups: a control group (C) undergoing natural fermentation and a treatment group (F) inoculated with L. plantarum. Both groups were then roasted using a medium roast profile (final temperature of 205°C). Sensory analysis was conducted using the SCAA cupping method by three trained panelists. The obtained data were tested statistically using an independent t-test at a 5% significance level (? = 0.05). This research conclusively demonstrates that the controlled fermentation treatment using the bacterium Lactobacillus plantarum combined with a medium roast significantly improved the sensory quality of Arabica coffee, Lini S variety, compared to natural fermentation (control). The SCAA cupping scores reinforce this finding, where the treatment group (F) inoculated with L. plantarum obtained a significantly higher total score (86.25) compared to the control group (C) (78.75). This score improvement was observed across all sensory attributes. The highest score increases were seen in the attributes of flavor (from 7.25 to 8.50), acidity (from 7.00 to 8.50), and balance (from 7.00 to 8.50). The study concludes that the effect of L. plantarum$ fermentation combined with a medium roast is a viable method for enhancing the sensory quality and commercial value of Arabica Lini S coffee.
