Implementasi Rahabilitasi Ekosistem Karang Menggunakan Terumbu Buatan dengan Memanfaatkan FABA di Perairan Pulau Ketawai, Desa Kurau Timur, Bangka Tengah

Abstract

The waste generated from the combustion of FABA (Fly Ash Bottom Ash) at a coal-fired power plant (PLTU) can serve as an alternative raw material for the construction of artificial reefs in the rehabilitation of coral reef ecosystems. In October 2023, the artificial reefs made from FABA were submerged in the Ketawai Island Waters, specifically in the Central Bangka Regency. This marked the first implementation of a community service project in the Bangka Belitung Province, particularly utilizing FABA-based artificial reefs. The reefs were crafted into 3D miniature characters inspired by a well-known American animated television series, SpongeBob SquarePants. Constructions involved a blend of cement and sand combined, reinforced with cast steel bars, and incorporating FABA as the key component in the raw material mix.
