An urbanist and founder of LabTanya, a community laboratory that develops various collective research, experiment, and participation methods for social transformation. Wilma co-initiated Kota Tanpa Sampah (literal translation: Wasteless City), an initiative and social experiment that began in 2015, engaging with the community to actively develop eco-conscious, low-waste knowledge and practice. Through an experience working with residents of 38 neighborhoods in Jakarta, South Tangerang, and Banjarmasin, Wilma observed that most of the contributing and committed residents were women. According to Wilma, women play a great part in solving the waste problem through their role in domestic governance, thus needing to be supported as a form of vernacular knowledge production.

Wilma strongly hopes that the works by the women involved would inspire the city to expand this movement, and that these women would serve as important actors for change.

In the past three years, Wilma and LabTanya have been assisting several neighborhoods in Jakarta and South Tangerang in the participatory planning for their waste management system.
