Measures for improving the adoption of higher efficiency appliances in Indonesian households: An analysis of lifetime use and decision-making in the purchase of electrical appliances

One approach to decreasing electricity consumption is to facilitate the replacement of older appliances with new, higher-efficiency. The objectives of this paper are to compare and analyse the replacement of appliances in two cities of Indonesia - Yogyakarta and Bandung - that are characterised by different cultural backgrounds, ethnicities, and decision-making processes in the household purchase of electrical appliances. A questionnaire survey method was employed to obtain information on behavioural economics and human psychosocial variables such as attitudes, beliefs and perceived benefits regarding the replacement and purchase of electrical appliances. The results show that refrigerators in Yogyakarta have a longer lifetime than in Bandung. However, in Bandung, air conditioners, electric fans, rice cookers, and water pumps have a longer lifetime than in Yogyakarta. These differences in the lifetime of appliances can be attributed to the cultural differences within the two cities that are reflected in the manner in which people use electrical appliances as well as to their lack of knowledge regarding appliance operation. An analysis of the factors influencing the purchase of appliances indicated that people in Yogyakarta show a greater awareness of the benefits of adopting higher-efficiency appliances than do persons in Bandung. The following suggestions could be implemented to improve the strategy of encouraging the adoption of higher-efficiency appliances: (1) in Yogyakarta, energy labelling could be applied to assist customers in understanding the rate of energy consumption of selected appliances; (2) in Bandung, the store sales staff could be trained to adapt their promotional messages to persuade people to purchase high-efficiency appliances and to promote the adoption of higher-efficiency models; and (3) the price of appliances could be correlated with the rate of energy consumption, and the total lifetime cost of use should be displayed in the store and included in promotional materials.
