Prevention of Littering through Improved Visual Design

Littering is a daunting environmental issue that occurs daily; the impact of littering can range from lowering the aesthetic appeal of a city to polluting waterways and biomes. Littering persists on a collective and individual level despite the existence of numerous laws and regulations that prohibit it. We assume that there is a correlation between the effectiveness of visual aids and littering behavior. Poorly designed prohibitive signs and inaccessible trash bins could be part of the reason why littering persists. The current research aims to evaluate existing prohibitive signs and trash bins and to design some improvements. The researchers used direct observation methods of visual designs based on socio-psychological persuasion techniques and a questionnaire conducted at the School of Environmental Science of Universitas Indonesia. The results showed that respondents were generally aware of littering being a serious issue that could lead to environmental problems. The university campus was generally clean; however, respondents stated that they often saw plastic trash in sewer and drainage areas. University residents do litter despite adverse social judgment. In addition, respondents stated that they responded better to visually pleasing encouragement posters rather than the standard prohibitive signs on proper waste disposal behavior.
