Abstract. Khasanah RI, Herawati EY, Hariati AM, Mahmudi M, Sartimbul A, Wiadnya DGR, Asrial E, Yudatomo, Nabil R. 2019. Growth rate of Acropora formosa coral fragments transplanted on different compositions of faba kerbstone artificial reef. Biodiversitas 20: 3593-3598. A counter measure and an alternative technique to reduce coral reef destruction is through transplantation, which requires the relocation or cutting of a live coral, planted in a designated place containing damaged varieties. Faba kerbstone is a product innovation similar to paving block/brick, made from fly and bottom ash (FABA), which is the dominant waste product from PT Jawa Power, Probolinggo, Indonesia. In addition, it has also been widely utilized as a raw material in the creation of paving and concrete blocks, composed by harmless material, with a length, width, and height of 40, 25 and 15 cm, respectively. This study aims to observe the growth rate of Acropora formosa coral fragments transplanted on a faba kerbstone, using five different fly and bottom ash compositions: K1 = 0% Fa, K2 = 25% Fa and 75% Ba, K3 = 50% FA and 50% Ba, K4 = 75% Fa and 25% Ba, while K5 = 100% Fa and 0% Ba. Furthermore, the observations were conducted underwater, using scuba diving for six months, observing the parameters of fragment length, colony diameter, and branches number. In addition, the highest elongation rate of A. formosa coral fragments was identified at K2 (1.313 ± 0.447 cm/month), and K1 (1.185 ± 0.642 cm/month), while the most significant increment in colony diameter was observed in K2 (0.077 ± 0.060 cm/month) and K1 (0.063 ± 0.071 cm/month), and the largest number of branches was also found in K2 (29.50 or 4.28 branches/month) and K1 (25.25 or 3.67 branches/month). Furthermore, the one-way ANOVA and Tukey's HSD test (p = 0.05) showed was no significant difference in the fragments elongation and colony diameters in the K1 and K2 models, although there was substantial variation from the K3, K4, and K5.

Motile cryptofauna inhabiting coral reefs are complex assemblages that utilize the space available among dead coral stands and the surrounding coral rubble substrate. They comprise a group of organisms largely overlooked in biodiversity estimates because they are hard to collect and identify, and their collection causes disturbance that is unsustainable in light of widespread reef degradation. Artificial substrate units (ASUs) provide a better sampling alternative and have the potential to enhance biodiversity estimates. The present study examines the effectiveness of ASUs made with defaunated coral rubble to estimate the diversity of motile cryptic crustaceans in the back-reef zone of the Puerto Morelos Reef National Park, Mexico. Species richness, Simpson’s diversity index, Shannon–Wiener index and the composition of assemblages were compared between ASUs and samples from the surrounding coral rubble substrate. A combined total of 2,740 specimens of 178 different species, belonging to five orders of Crustacea (Amphipoda, Cumacea, Isopoda, Tanaidacea and Decapoda) were collected. Species richness was higher in the surrounding coral rubble and Shannon–Wiener and Simpson indexes were higher in ASUs. Species composition differed between methods, with only 71 species being shared among sampling methods. Decapoda was more speciose in ASUs and Peracarids in the surrounding coral rubble. Combining the use of ASUs with surrounding rubble provided a better inventory of motile cryptic crustacean biodiversity, as 65% of the species were represented by one or two specimens.

Corals are associations of millions polyps that live in symbiotic way with zooxanthellae algae. Most of the polyps live in colonies and form a reef. Coral reefs are rich ecosystems that contain diverse organisms living in it. However, the threat of damage increases with the pressure that enters the waters. Coral transplantation is one way of restorations that can be done to restore damaged corals by cutting live corals and then planting them in places where the corals have been damaged. This study aims to determine the growth rate of Acropora formosa corals that were transplanted on fixed and hanging media. Data was collected in Malalayang Coast Waters, Manado City, North Sulawesi. The research took place for seven months. Beginning with the coral transplant activity of Acropora formosa on fixed and hanging media, then continued with monitoring every month for six months. Transplanted corals were measured using a ruler to determine the length of the coral from the beginning to the end of the study and then the data was analyzed using Microsoft Excel. The results obtained for the average growth rate of Acropora formosa corals transplanted on fixed media were 0.8 cm and on hanging media 1.8 cm. Overall growth rate averaged 1.3 cm.Keywords: Coral, Coral Reef, Transplant, Acropora formosa.
