Nusantara Bersih began as a student-led initiative founded by Kayleen as part of her Creativity, Activity, and Service (CAS) project within the International Baccalaureate curriculum.

Driven by a shared desire to contribute to a cleaner and healthier society, Kayleen formed a team with Ashley and Serafina. Together, they developed Nusantara Bersih into a project focused on improving hygiene access across Indonesia through practical, sustainable, and locally inspired solutions.

What started as a school project gradually grew into a wider mission. Through research, product development, and community outreach, the team created Kotak Kebersihan Indonesia, cleaning kits designed to support families and communities in maintaining cleaner and healthier living environments.
