This is part of a Design Thinking Workshop, a multi-disciplinary project, held in school during my second year. My team went to survey Hamparan Perak, a village in Medan, Indonesia. We worked alongside Mercy Relief, a non-governmental humanitarian charity organization, to observe and understand some of the difficulties that the villagers face. Shortage of money, insufficient electricity and unclean water are just some of the examples to name. Then we generated ideas to help the villagers solve some of the problems.

The team decided to solve the problems of improper disposal of crop waste and the insufficient electricity at night. We found that the villagers use car batteries as sources of electricity during nighttime. Our ideas were to use the resources available on site such as water drums as composting barrels and an unused dam to generate hydroelectricity. After a few rounds of critique sessions, we decided to merge the composting barrels and a turbine which is used to charge multiple car batteries together.

As a result, composting barrels provide compost for personal or commercial uses, while the turbine charges car batteries for additional electricity at night.
