Abstract

Caulerpa is a green macroalgae found on Lemukutan Island, West Kalimantan. Caulerpa contains bioactive compounds that have potential to inhibit the alpha-glucosidase enzyme for people with diabetes mellitus. Inhibition of the alpha-glucosidase enzyme will have an impact on delaying glucose absorption. In addition, it is necessary to carry out a toxicity test to detect toxic effects and assess safety in the use of compounds. Therefore, the purpose of this study was to determine the inhibitory activity of the alpha-glucosidase enzyme and the toxicity of the ethanolic extract of Caulerpa seaweed in Lemukutan Island waters. Identification of secondary metabolites was determined from phytochemical tests. Inhibitory activity of the alpha-glucosidase enzyme determined by using enzymatic reactions, while the toxicity by method of BSLT. The showed that the percentage yield of Caulerpa ethanol extract was 3.66%. The content of bioactive compounds in the ethanolic extract of Caulerpa contains positive alkaloids, flavonoids, saponins, tannins, steroids, and phenolics. The inhibitory of the alpha-glucosidase enzyme had the highest percentage of inhibition with a concentration of 300 ppm indicating a percent inhibition of 16.85%. Toxicity obtained LC50 value of 598.19 ppm which is classified as low toxic.

Abstract

Cempedak Island is one of the Coastal and Small Islands Conservation Areas (KKP3K) in West Kalimantan has various marine biological resources and important ecosystems, including seagrass. Seagrass is used as the main food source for dugong, potential habitat for various types of organisms, and potential to be developed as marine ecotourism. On the other hand, seagrass ecosystems faced threats, such as high sedimentation and the influence of anthropogenic activities. It is unknown about the current status of seagrass on Cempedak Island. This research aimed to analyze the structure of seagrass in the southeastern waters of Cempedak Island. Seagrass data collection was carried out in the tidal zone using line transect of 70 m and a quadratic transect of 1x1 m2. Data collection on seagrass and water parameters was carried out in October 2023. Determination of research sites was done using an explorative method based on the presence of seagrass. The seagrass found consisted of 4 species, namely Enhalus acoroides, Cymodocea rotundata, Halodule pinifolia, and Halophila ovalis. Seagrass cover ranged from 9.17–16.74%, with an abundance of 1.4–373.3 ind/m2. The diversity index (H') is in the low to medium category, the uniformity index (E) is in the medium category and the dominance index (C) is in the low category. Conditions of water quality parameters were into the optimal range to support seagrass life.

Abstract

Desa Sungai Nibung is a village located in Teluk Pakedai District, Kubu Raya Regency, West Kalimantan. This village is one of the conservation areas established by the Regional Government of West Kalimantan Province in 2020. Desa Sungai Nibung has a high diversity of natural resources, one of which is gastropods. Gastropods are organisms that act as grazers, scavengers, and predators. These organisms can live in waters, coastal and terrestrial. Its diversity has been reported to be more than 75,000 species. Several gastropods have been used by the local community as food with a high protein source. Gastropods found on the coast of Sungai Nibung Village are Ellobium, Cassidula, Nerita, Neritina, Chicoreus, Cerithidea, Littoria, Potamopyrgus, and Onchidium.

Abstract

Desa Sungai Nyirih, as one of the coastal villages in Jawai District, West Kalimantan, has the potential for a mangrove ecosystem with a diversity of aquatic biota, including bivalves. Most of the coastal communities in West Kalimantan catch and consume shellfish because it contains high nutrients. Therefore, shellfish can be an alternative source of animal protein. The aim of the study was to identify the genus of bivalves in the mangrove area of Desa Sungai Nyirih, Jawai District, West Kalimantan. The collection of bivalves was carried out using the exploratory method, as many as ±5 individuals of each genus were collected and all genera of bivalves were identified. The results showed that there were two genera found, such as the cockle (Geloina expansa) and the blood clam (Tegillarca nodifera).

Abstract

Plastic waste has become a national and international issue. Plastic waste will degrade into smaller sizes, such as microplastics. Microplastic contamination can occur in coastal and marine areas which can have a negative impact on the environment, disrupting the balance of the ecosystem and aquatic biota. Sungai Jebung located in the coastal area of Desa Sungai Nibung, has the potential to microplastic pollution. This research aims to identify the type, density and type of polymer of microplastics in Sungai Jebung, Desa Sungai Nibung, West Kalimantan. Water sampling was carried out at three stations with two repetitions. Identification of microplastic types was carried out using a binocular microscope and polymer analysis was done using FTIR. The types of microplastics found in the water samples consisted of films, fibers, fragments and pellets. Film and fiber have a higher percentage compared to other types. The average total density of microplastics was 3,188.94 particles/L. The types of polymers found include polyethylene (PE), polystyrene (PS), and polytetrafluorethylene (PTFE).
