Mobile Crowdsourcing App Design: Managing Waste Through Waste Bank in Rural Area of Indonesia

Waste bank management is one of the efforts to reduce waste piles, prevent environmental pollution, and function as a socio-economic community. This effort is in line with the concern of the United Nations in achieving the Sustainable Development Goals, especially Goal 11 (Make cities and human settlements inclusive, safe, resilient, and sustainable). However, the lack of community participation in waste bank activities is an obstacle to managing waste banks. One of the reasons they have yet to become participants or customers of Waste Bank is that it takes a long time to collect their waste until it is ready to be deposited into the waste bank. Based on these problems, we propose a crowdsourcing mobile application design solution for community participation in waste management. It can be a solution to involve the community in waste bank activities, one of which is collecting waste together (crowdsourcing) so that waste can be collected more quickly and reporting locations where there are landfills. The design of this application's user interface uses the design thinking method and produces nine design solution features in the form of an interactive prototype named Klik Sampah. Usability Testing of the Klik Sampah application prototype was carried out based on ISO 9241-11 and obtained a score of 89.84%, which is included in category A (Excellent). This study also shows that user preferences for the Klik Sampah application design solution depend on the habits and amount of waste collected by each user. If the amount of waste collected is too small, users prefer to collaborate with other users to collect more waste, deposit it in the Waste Bank, and get more rewards.
