Demographic Characteristics in Correlation with Household Electricity Use

Household has been identified by researchers as an important target group of energy conservation. User behavior in utilizing electricity becomes significant. Energy consumption in the residential sector offers an important opportunity for conserving resources. This study attempts to identify the role of the economic behaviour of resident households. In this paper, we analyse the extent to which the use of electricity is determined by the technical specifications of the dwelling as compared to the demographic characteristics of the residents. Analysis is based on a sample of 210 Padang homes and their occupants. Results show that electricity consumption varies more directly with household composition. The results provide a scientific evidence for stakeholders on the potential of controlling electricity consumption and designing energy policy in residential sector

Ergonomics intervention on an alternative design of a spinal board.

A spinal board is the evacuation tool of first aid to help the injured spinal cord. The existing spinal board has several weaknesses, both in terms of user comfort and the effectiveness and efficiency of the evacuation process. This study designs an ergonomic spinal board using the quality function deployment approach. A preliminary survey was conducted through direct observation and interviews with volunteers from the Indonesian Red Cross. Data gathered were translated into a questionnaire and answered by 47 participants in West Sumatra. The results indicate that the selection of materials, the application of strap systems as well as the addition of features are very important in designing an ergonomic spinal board. The data were used in designing an ergonomic spinal board. The use of anthropometric data ensures that this product can accommodate safety and comfort when immobilized, as well as the flexibility and speed of the rescue evacuation process.
