Design guidelines for sustainable utilization of agricultural appropriate technology: Enhancing human factors and user experience

The utilization of appropriate technology (AT) has become the Indonesian government strategy to increase productivity of agricultural commodities due to its simplicity and cost-effectiveness. However, the current utilization of AT remains suboptimal mostly due to design deficiencies that insufficiently account for human factors and user experience. In response, the aim of this study is to establish comprehensive AT design guidelines for sustainable AT utilization, focused on agricultural processing machines. An intensive observation was initially conducted in a rural community in Indonesia, to summarize difficulties faced by AT users. Supported by an exhaustive review of literature, a total of 44 human factors related design criteria were defined. Subsequently, these criteria underwent rigorous validation through a questionnaire administered to 197 respondents, consisting of AT designers, experts, and users. Employing the framework of principal component analysis (PCA), novel dimensions of AT design criteria were suggested, encompassing safety and error prevention, functionality and economics, user-friendly, low physical effort, physical workspace compatibility, and perceptible information. To augment the insights gleaned from the PCA, a matrix of importance-performance analysis was created, affording a map of the relative significance and concurrent performance of the defined criteria. The implications of this study are further discussed.
