Abstract
Artificial reefs are structures that can be natural or artificial materials that are intentionally placed on the seabed, placed at one time or over a long period of time, and ideally will work as part of a natural ecosystem. In artificial reefs deployment, it is necessary to pay attention to several factors so that the artificial reef itself functions optimally. Therefore, competent human resources are needed through the correct technical understanding of artificial reef deployment. The less-than-optimal deployment of artificial reefs in Damas waters is caused by a lack of understanding of human resources, so that when monitoring was carried out, it was found that 22 of the 25 artificial reefs found were mostly in poor condition.
TopBackground
The Artificial Reef Structures
Artificial reefs are structures that are intentionally placed on the seabed to achieve the biological but also socio-economic or engineering goals of one or more stakeholders. The structure can be of natural or artificial material, placed at one time or over a long period, and will ideally serve as a habitat that functions as part of a natural ecosystem (Lindberg & Seaman, 2011). The forms of artificial reefs certainly have advantages and disadvantages depending on the type of base material.
These objects are expected to be a place for new coral animals to attach (Sirait et al., 2021; Thaeraniza et al., 2020). The submerged artificial reef model is a hollow concrete cube model. The surface area of the artificial reef was measured directly underwater using a sewing meter. Each rib is 60 cm long and 8 cm thick. The dimensions are presented in Figure 1.
