Mobile application development for environmental informatics and feedback on cooking oil use and disposal in Indonesia

A web-based mobile application was developed to investigate cooking oil use and disposal of households in Indonesia, and released in February, 2014. The application was designed as an interactive program visualizing Green House Gas emission calculated by individual cooking oil consumption and disposals, as well as a potential GHG reduction if the same amountof waste cooking oil was recycled. On 13 and 14 February, 2014, the released mobile application was demonstrated at three high schools, SMA2, SMA3, SMAPGRI4 in Bogor, Indonesia. The responses of 188 households were collected by a mobile application and paper questionnaires. The results showed that 51% of households disposed waste cooking oil to drainage.17%to soil, and 15% gave it to maids for further use. The average monthly consumption and disposal of cooking oil were 3.6L and 0.8L respectively. The feedback of the GHG emission by user´s own cooking oil consumption and disposal seemed to have enhanced users´ environmental recognition and incentive to participate in Bogor City´s waste cooking oil recycling program. The application was proved as an environmental informatics and feedback system of daily food consumption and disposal.
