“…Almost all types of coral are very sensitive to changes in physical and chemical waters (Luthfi et al, 2017), so the water parameters in the aquarium need to be considered and maintained properly. The results of the physical and chemical conditions of the waters can be seen in (Table 1).…”

The phylum Coelenterata, class Anthozoa, includes a group of marine living things known as corals. Due to its geographic setting, Indonesia has an extremely high level of coral diversity and is the world's largest exporter of ornamental coral. Demand on the market for natural ornamental corals is now rising, along with trends in the rate of industrial development. Allowing this industrial activity to grow will result in huge exploitation and put the coral reef environment at danger. Therefore, to quickly increase the number of corals, this research examined transplantation methods. The montipora and echinopora genera were the focus of this study. The Montipora capricornis coral sample from PT. Tirta Samudra Bali had the highest growth rate of the Montipora genus corals, with an average growth rate of 1,404 cm 2 /week. The highest growth rate of the Echinopora genus corals had an average growth rate of 0.362 cm 2 /week. As they have a 100% survival record, cultivation activities using the transplant method performed at PT. Tirta Samudra Bali are regarded as successful.

“…For example, while an excess of Cu and Zn can be toxic, these elements are vital for coral growth, forming parts of various enzymes like cytochrome oxidase (Cu, Medeiros and Jennings, 2002) and carbonic anhydrase (Zn, Morel et al., 1994). They also play significant roles in electron transmission during zooxanthellae photosynthesis, reactive oxygen clearance in the coral body, and coral calcification (Ferrier‐Pagès et al., 2005; Luthfi et al., 2017; Nyström et al., 2001). Mo is another critical trace element, serving as a key component in enzymes related to carbon, nitrogen, and sulfur cycling (Mendel, 2013; Schwarz et al., 2009).…”

In the face of diverse challenges like global warming, ocean acidification, and human activities, the world's coral reefs are confronting a severe ecological crisis. Understanding the historical coevolution of corals with their environment and their resilience to current climate change is crucial for protecting these ecosystems and predicting their future. In this context, metal stable isotopes in corals present a novel and alternative methodology. Their significant fractionation during coral biological processes, persistent presence in coral skeletons, and relatively straightforward sources make them a valuable tool. However, the complexity of coral biology necessitates a deeper investigation into the fundamental mechanisms behind the isotopic fractionation of these biologically utilized metal elements. A comprehensive and systematic study of the roles of metal stable elements in coral biological processes is essential. This includes examining the fractionation of metal isotopes across different parts of the corals, such as tissues, zooxanthellae, and skeletons. To achieve these goals, multidisciplinary collaborations are essential. They should focus on several key areas: interpreting metal stable isotopes data in the context of coral physiology and ecology; conducting controlled laboratory experiments on coral cultivation; engaging in comparative studies with inorganically precipitated aragonites; and developing a holistic understanding within the framework of coral biomineralization models.

“…The availability of trace metals spread out in water column due to the upwelling, anchoring, dredging, volcano activity, and terrestrial input. Hence, various environment of coral reef grew in around the world with different degree of pollution, colony size, and species resulted in different concentration of heavy metals bound in the skeleton (Luthfi et al, 2017).…”

Coral reef is a massive natural building block that mainly composed of hard coral. In ecological view coral reef is the center of biological activity for shelter, foraging and feeding place. Porites lutea is a common coral in reef flat area such as in Pantai Kondang Merak. This coral can form a massive with hillocky colony surface and has a slow linear extension rate, that made this coral has long longevity. The annual growth band of coral skeleton provide information of pollutants in the coastal extending back over several years ago due to ability of coral aragonite traped trace metal from environment. The aim of this research was to determine the concentration of trace metals of Cd, Cu and As along with the coral annual banding. The heavy metals detection was performed using ICP-OES (iCAP 7400 Series). The concentration of Cd, Cu and As in sample 1 (KM1) were 2.236 mg/kg, 9.726 mg/ kg, and 2.474 mg/kg, while sample 2 (KM2) were 1.989 mg/kg, 19.157 mg/kg, and 2,064 mg/kg respectively. Two ways mechanism of trace metals to be trapped in the coral skeleton are by direct mechanism when trace metals in a form dissolved ion that were uptaken by coral then stored into coral skeleton and by indirect mechanism when particulate metals ingested by plankton then eaten by coral through coral tissue. The tracing of heavy metal in coral is provided important information of environment condition of the sea from 2009 -2015 that may be used for authority decision regarding pollutant ambient in the sea environment.
