The festival marked 29 years of mangrove rehabilitation at the site from roughly 9 hectares to about 65 hectares of healthy forest across a 99.82-hectare area once used as illegal fish ponds, now home to wildlife including sea eagles. The event opened with remarks from Ir. Ken Savitri Ambarsari, MBA, President Director of TWA Angke Kapuk, followed by a wildlife photography exhibition by Ezron Tarigan and hands-on workshops (Eco Print, Pottery, Rattan Weaving) attended by 100+ participants, plus 500+ volunteers mobilized by Jiva Catalyst.

A talk show titled “Roots of Change: The Role of Communities in Protecting Mangroves for a Better Climate Future” featured Maya Lynn BC (Jiva Catalyst founder), Putri Melta Sari (Trash Ranger Indonesia co-founder), and Fitra Gautama (TWA Angke Kapuk management), who spoke on mangroves’ role in preventing abrasion and filtering marine waste, and the need for stronger community involvement. This was followed by a clean-up, mangrove tour, and a performance by Lahila Band.
