Drinking coffee has currently become one of the new lifestyles of young people in Yogyakarta and the increasing coffee shop business facilitates tight competition. The previous research on coffee shops focused on service quality or customer satisfaction analysis. Due to the changing of the business environment, elaborating how customers decide to buy coffee shop product is important. Therefore, this research aims to examine the influence of service quality and brand image on the purchase decisions of coffee shop products. A quantitative approach of multiple regression analysis was used, while the samples were three coffee shops in Yogyakarta with different characteristics such as the length of service experience, location, and shop size. The result showed that both service quality and brand image significantly influenced purchase decisions. The service quality significantly influenced the 3 shops, but only 1 was influenced by brand image. Hence, service quality and brand image are useful for coffee shops with certain characteristics such as the business location.
The majority of coffee plantations in Indonesia is dominated by Robusta coffee. Some of them have a distinctive quality with a strong relation to their origin, in which the coffee has been cultivated. These are known as single-origin coffee. Most of the coffees are produced in the western part of the country. This study aimed to profile the chemical quality parameters of robusta single-origin coffee in the western part of Indonesia. Green coffee bean from various regions of the western part of the country, namely Empat Lawang, Menoreh, and Gunung Kelir, which were cultivated at various elevation ranges, were collected and analyzed in their chemical quality parameters such as caffeine, sucrose, total fat, and fatty acids. ANOVA was then performed on the collected data, and the results are discussed in this paper.
