The roaming method is carried out at 2 stations with data collection that is 100 m long. Next, data collection using the quadratic transect method was carried out by drawing a 10 m long transect line and placing a quadratic plot in a zig-zag manner next to the transect line. There were 5 plots observed measuring 1m x 1m with a plot distance of 2 m. Determining the distance of each station is 50 m from the first transect line and other transect lines. The results of research on the waters of Tambala Village that were obtained as a whole included four classes, namely Asteroidea, Holothuroidea, Echinoidea, and Ophiuroidea with a total of 8 types.

The outbreak of COVID-19 to date indicates an urgency to find and develop effective therapeutic agents. One alternative that needs to be explored is to design drug candidates from marine fauna. Marine microbes have promising molecular potential as a source of pharmaceutical biomaterials, including Prochloron didemni which associated with Ascidiacea belongs to the invertebrate subphylum Tunicata in Manado Bay, North Sulawesi. This microbe has been isolated from its host Lissoclinum patella and cultivated in the laboratory. P. didemni has been reported to produce several cyclic peptides including patelamide E compound. One approach to develop this compound as antiviral drug is in silico analysis using AutoDock. This analysis aims to predict the ability of patelamide E compounds to inhibit the activity of the non-structural protein (nsp13) SARS-CoV-2 which is known to play an important role in the viral replication. Its molecular structure was downloaded from the RCSB Protein Database with ID 6ZSL. As ligands, the molecular structure of patelamide E and the recommended drugs for COVID-19 (ivermectin, remdesivir, malnupiravir, favipiravir and oseltamivir) were downloaded from https://pubchem.ncbi.nlm.nih.gov/. The binding affinity between the protein and the ligand was assessed using AutoDock and visualized by PyMol. The results show that the free energy (∆G) value of -15.4 kcal/mol was obtained for binding affinity of patelamide E towards nsp13 SARS-CoV-2, indicating that this compound could inhibit the viral replication. The inhibitory ability of patelamide E is stronger than the recommended drugs (ivermectin, remdesivir, malnupiravir, favipiravir and oseltamivir) with ∆G values ranged from -6.7 to -13.7 kcal/mol. This analysis is obviously necessary to accomplish with further computer simulation for assesing the binding stability.
