Abstract

The quality of the Garlic seed bulbs needs to be improved by seed propagation through tissue culture techniques to get uniform and big cloves. Utilizing the suitable color spectrum of light is one way to stimulate plant morphogenesis. This study aimed to identify the influence of light color and obtain the best color in the morphogenesis of garlic callus explants. This research was carried out from June to September 2022 at the Tissue Culture Laboratory, Faculty of Agriculture, Universitas Andalas. This study used a completely randomized design with three treatment levels: red, blue, and white. The F test analyzed observational data at a 5% level, followed by Duncan's multiple Range Test (DNMRT) at a 5% level. The results showed light color influences embryogenic callus formation and shoot formation from garlic callus explants. Blue light is better than red and white light in inducing embryogenic callus, increasing the rate of explants forming shoots but giving no significant difference in the length of the shoot.

Abstract

Competition in the culinary industry requires restaurants not only to excel in product quality but also to manage their resources efficiently. This study aims to optimize employee assignment in the bar section of Ever Green Restaurant to minimize operational time using a scientific approach. The research employs a quantitative approach with a case study design, in which primary data were obtained through direct observation and time measurements of five bar employees performing five different beverage-related tasks. The collected data were then analyzed using the Hungarian Method based on the one man one task principle. The results indicate that the application of the Hungarian Method produces an optimal assignment configuration with a minimum operational time of 17 minutes. This assignment allocates each employee to the task most aligned with their competencies, thereby reducing waiting time and workload imbalance. These findings suggest that the application of optimization methods provides a more objective approach to improving operational efficiency and service quality in restaurants.
