Abstract

The purposes of the research were to: 1) develop a mobile application for calculating electricity costs of home appliances and 2) study the user satisfaction of the application for calculating electricity costs of home appliances. The sample group included 44 employees of N.P. Unipack Co., Ltd., living in Staff Housing, Zone 1, in the area of House No. 291/3, Moo. 2 Ban Khlong Suan Sub-district, Phra Samut Chedi District, Samut Prakan Province. The tool used to develop the home appliance calculation application was a Kodular application. The research instruments used to collect opinions from the experts and the employees from the sample group were the application quality assessment forms and the application satisfaction assessment forms. The statistics used to analyze the data were percentage, mean, and standard deviation. The results showed that: the overall result of the quality assessment of the application for calculating electricity costs of home appliances examined by the experts was at a high level ( X= 4.10, S.D. = 0.13); and the overall result of the assessment of satisfaction with the use of the application for calculating electricity costs of home appliances determined by the employees of N.P. Unipack Co., Ltd. was also at a high level ( X= 3.77, S.D. = 0.73). It was also discovered that application users could apply their knowledge to determine the costs of home appliances and future expenditures.
