Echinoderms are very important in marine ecosystems and are useful as a component in the food chain. Echinoderms can be detritus eaters, herbivores, carnivores and omnivores. This research was conducted for 2 weeks. The methods used are the cruise method and the quadrat transect method. 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. Based on data analysis using the quadratic transect method, it was obtained: at station I H' = 1.067, the highest species density of Echinometra mathaei was 6.4 ind/m2 and the relative density was 55.49%, while at station II it was obtained H'= 0.831, the density the highest species Ophiocoma erinaceus was 15.53 ind/m2 and the relative density was 54.56%.Keywords: Echinoderms, Diversity, Abundance of species ABSTRAKEchinodermata sangat penting di dalam ekosistem laut dan bermanfaat sebagai salah satukomponen dalam rantai makanan.

Anti-UV compounds are compounds used for making sunscreen or sunscreen/sunblock that can absorb sunlight. Several classes of antioxidant active compounds such as cinnamates, flavonoids, tannins, quinones, and others have been studied to have the ability to protect the skin from UV rays. The purpose of this study was to determine the anti-UV substance of extracts of three types of sea cucumbers H. atra, H. scabra and S. maculata. This test was conducted using spectrophotometric analysis method using UV-Vis spectrophotometer. Spectrophotometer is a tool used to measure energy relatively if the energy is transmitted, reflected or emitted as a function of wavelength. The results of the anti-UV activity test showed that the three sea cucumbers were able to absorb UV A at 320-400 nm. From this study it can be concluded that sea cucumbers have the potential as anti-UV. It is suggested that it can be further researched with the purification stage.

The COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has lead to a global health emergency. 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. The potential of patelamide E as an anti-SARS-CoV-2 drug candidate should be more clinically assayed after in vitro and in vivo analyses.Keywords: Molecular docking, nsp 13, patellamide E, SARS-CoV-2, marine microbes

The purpose of this study was to determine the type and diversity of macrobenthos that inhabit the aggregation of Septifer bilocularis shellfish in the coastal waters of Tiwoho, North Minahasa Regency, North Sulawesi. Sampling of macrobenthos was carried out using core (PVC), both at the position of small aggregation (AK), middle large aggregation (ABT), and large edge aggregation (ABP). Sampling was carried out 4 times on different aggregations of shellfish. The data has been analyzed using the Diversity Index (H), the dominance index (D), and the Uniformity Index (E). It was identified that there were 25 types of macrobenthos occupying all aggregations of septifer bilocularis shells, which came from 11 classes including Gastropods, Bivalves, Malacostraca, Florideiphyceae, Ulvophyceae Ophiuroidea, Clitelatta, Maxillopoda, Globothalamea, Tubothalamea and Phaeophyceae. Biota diversity index varies from 1.60 – 1.70 which indicates that the biota in each aggregation has moderate diversity. The uniformity index value also varied, namely 0.069 for macrobenthos occupying the small aggregation (AK), then 0.066 in the middle large aggregation (ABT) and 0.064 in the large margin aggregation (GBP), which indicates the low uniformity of the macrobenthos in each aggregation. The dominance index of all aggregations was obtained between 0.27 - 0.36, which indicates that there is no species dominance for macrobenthos occupying different shellfish aggregations.Keywords: Diversity, Macrobenthos, Septifer bilocularis, Tiwoho

Mangrove forests play an important role in mitigating the effects of global warming as mangroves can absorbs and stores carbon therefor, mangrove plants including A. marina can act as carbon sinks. The study aim is to estimate the carbon content contained in A. marina pneumatophore biomass. The data was taken b using line transect method. The number of research stations are 3 stations contain 3 plots (10 x 10 m2) for each station. Samples were taken at low tide by established 3 microplots (50 x 50 cm2) in each 10 x10 m2 plots. The results showed that the highest biomass value was found at Station 3 of 0.49 Kg/m2, followed by Station 1 of 0.42 Kg/m2, and the least pneumatophore biomass value was found at Station 2 of 0.41 Kg/m2. This finding is in line to the potenntial potential carbon content in pneumatophores where Station 3 has C content (0.08 Kg C/m2), dand 0.07 Kg C/m2 for both station 1 and 2 respectively. The average of C Contain in pneumatphores was 0.28 Kg C/m2. Keyword : Carbon Content, Biomass, Pneumatophores, Avicennia marina

Seagrass ecosystems services in the coastal waters are included as primary producers, nutrient recycler, bottom stabilizers, sediment traps, and erosion barriers. Gleaning fisheries in seagrass bed in Mokupa waters could cause damage on seagrass, that can be marked by changes in seagrass cover. The purposes of this study were to identify the types of seagrasses and to determine the health condition of seagrass bed ecosystem in Mokupa waters. The research method used in this study is quadrat transect method. Data collection was carried out by laid three transects (100 m) with distance between each transect was 50 m. A square frame (50×50 cm2) which is divided into 4 squares is placed on the right side of the transect, with 10 m distance between frame. This study found four types of seagrasses, namely Enhalus acoroides, Thalassia hemprichii, Halodule pinifolia and Halophila ovalis. E. acoroides have the highest percentage cover (16.19%) followed byT. hemprichii (6.91%), H. pinifolia (4.50%) and H. ovalis (1.56%) respectively. Seagrass cover in the study area is considered medium (26-50%) while the health condition was poor (29.25%).

Padina australis is a species of marine algae from the Phaeophyta division (brown algae) which is generally distributed in marine waters. This algae is able to live in waters with high levels of heavy metals such as in the Kima Bajo waters. This study aims to isolate arsenic (As)-resistant bacteria in P. australis, observe cell shape and bacterial characteristics, and determine bacterial resistance to antibiotics. The method used is conventional bacterial isolation which has been tested on As2O3 compounds. The results obtained were that P. australis contained arsenic resistant bacteria at concentrations of 250 ppm, 500 ppm, and 1000 ppm. The bacteria obtained were Gram positive, in the form of bacilli. These arsenic-resistant bacteria are also resistant to antibiotics such as amoxicillin, cefixime, and doxycycline.Keywords: Padina australis, Arsen (As), Kima Bajo
