Tasya is the Executive Director and Co-Founder of Biorock Indonesia, an Organization which established following the International award-winning foundation, Yayasan Karang Lestari Teluk Pemuteran, based in Bali. The organization focused on coral reef restoration using cutting edge Biorock technology, so coral grows faster and healthier, even in poor water quality. Unfortunately, Coral Reef Restoration mistakenly understood as the ceremonial event which focused on the amount of coral transplant and press coverage only, instead of the process of restoring the coral reef ecosystem resulting 36,18% of coral reef in Indonesia still in damaged condition. By using community-based and blue economy approach, the community will take the initiative to restore coral reefs, protect the restoration area, and at the same time gaining income to feed their family and run the project for decades until the coral reef fully recovered.

Tasya has been involved with Biorock since 2003, a technology that creates artificial coral reefs from the accumulation of minerals. She received the opportunity to study Biorock technology with the inventors, Prof. Wolf Hilbertz and Dr. Tom Goreau. Her university thesis on Application of Biorock to Pearl Oyster Juvenile, Pinctada Maxima was presented worldwide during a conference organized by the Society Ecological Restoration in Merida, Mexico in 2011. Her research was also published in “Innovative Methods of Marine Restoration”. Since 2014, she has lead more than 15 Biorock Indonesia’s projects with the help of her team and partners, from surveying to planning, to installation and maintenance. Currently, Tasya and her team are working closely with Indonesian Ministries and UNDP Indonesia to prepare community-based coral reef restoration with Biorock technology in archipelagic island states.

She worked as a Consultant for Clean Development Mechanism for five years and is also an expert in community involvement strategy and managing nonprofit projects. Tasya worked previously at the Child Protection NGO and Bird Conservation Foundation in administration and management.

Including her amazing work for Biorock, Tasya is also an advocate for women’s empowerment and equality. As a mother of three young children, Tasya understands the challenges that can come with being a working mother and promotes a work/family balance among her teammates.
