Abstract

Naturally, the human body has tolerance to free radical attacks. However, the natural antioxidant ability will decrease when exposure to free radicals from within and outside the body occurs intensively. Antioxidants play potential preventive role to protect the body from damage associated with oxidative stress by free radicals. One of the potential marine resources used as an antioxidant is macroalgae. Turbinaria is widely distributed in tropical waters of Indonesia, including West Kalimantan. This genus produces secondary metabolites with several biological activities. This genus abundantly grows in Kabung Island. However, it has not been used by the local community, even tends to be considered as a weed that disturbs others marine biota. This study aimed to evaluate the potential antioxidant activity of tropical brown macroalgae Turbinaria ethanol extract from Kabung Island, West Kalimantan. antioxidant activity was evaluated using the DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenger method with UV-vis spectrophotometer. The result showed that the ethanolic extract had a high of potential antioxidant activity which IC50 was 87.31 mg/L and it was classified into strong antioxidant potential.

Abstract

Lemukutan Island in West Kalimantan has marine natural resources with a high level of diversity such as seagrass, coral reefs, macroalgae, and gastropods. Gastropods are one of the largest Mollusc phylum groups that are abundant in the waters of Lemukutan Island. Several types of gastropods have been reported to have high economic value and high nutritional content as well as macro minerals such as Na, Ca, K, F, and P. Therefore, these biota are more widely used as food. This study aims to analyze the proximate and mineral content of gastropods (Lambis and Monetaria) from the waters of Lemukutan Island. The moisture content and ash content of the sample were determined by the gravimetric method. The results of the study found that macro mineral content was determined in Lambis and Monetaria by Atomic Absorption Spectrophotometer (AAS). The protein content in both types of gastropods is quite high. Monetaria has a higher protein content (63.69%) than Lambis (50.06%). However, the fat content in Lambis is 1.88% and Monetaria is 1.14%. The highest mineral content of these two types of gastropods is iron (Fe). Lambis and Monetaria have Fe content of 0.2762 mg/kg and 0.1818 mg/kg, respectively.

Abstract

Xestospongia sp. is a barrel sponge belonging to the phylum porifera of the class Demospongia. This sponge abundant in coral reefs ecosystem. It is a filter feeder where the filtering of nutrients available in the environment occurs in the pores along the body. Various microorganisms in the seawater were exposed to sponges, so that they can produce various biological activities. This study aims to determine the antioxidant activity of crude protein from sponge Xestospongia sp from Spermonde waters of Sulawesi Island. The protein of the sponge was extracted using ammonium sulfate. Then, the protein was determined by the Lowry method in each fraction. Furthermore, the antioxidant activity was carried out by the DPPH method. The crude protein extracts in various fractions produced intermediate antioxidant activity produced from each fraction. They are fraction 1 (0-30%) of 81.31 ppm, fraction 2 (30-60%) was 180.22 ppm, and fraction 3 (60–90%) was 93.97 ppm, while crude protein was 128.33 ppm.The ascorbic acid as a positive control has antioxidant 2.98 ppm.

Abstract

Sargassum belongs to Phaeophyceae is widely distributed in Indonesian waters, including Kabung Island. Seaweed has bioactive compounds that potential to be developed. In the health sector, one of the global problems that still increasing is the bacterial infection. This condition leads us to explore antibiotic from natural resources to overcome this problem. Sargassum grow abundantly in the waters of Kabung Island and this genus has not been utilized by local community. For this reason, the aim of this study is to evaluate the antibacterial and cytotoxic activity from ethyl acetate extract of Sargassum from Kabung Island, West Kalimantan. Antibacterial activity test of the ethyl acetate extract against E. coli and S. aureus was conducted using the diffusion method with concentration series of 100; 50; 25; 5; 1; and 0.1 g/mL. While, the assessment of cytotoxic activity was carried out with concentration of 10; 100 and 1000 g/mL. The result showed that ethyl acetate extract of Sargassum from Kabung Island only showed antibacterial activity against E. coli bacteria. The greatest inhibition zone was 11.59 mm at a concentration of 100 g/mL, while in the cytotoxic test exhibited that the LC50 was more than 1000 ppm, so it was considered into non-toxic category.

Abstract

Desa Bakau is located in Sambas Regency, West Kalimantan which has the potential for mangrove forests with an area of ± 305 Ha. Ecologically, mangrove forests have various roles, one of them is as a habitat for various types of aquatic biota, including gastropods. Several gastropods have important economic value for the community as food and medicine. The local community catches and consumes the mangrove gastropods. As a food ingredient, gastropods have a high nutritional content and essential macro minerals. Gastropods can be used as an alternative source of animal protein at an affordable price. This study aimed to determine the nutritional value of the gastropod Cassidula from the mangrove area of Desa Bakau, Sambas Regency, West Kalimantan. Quantitatively, nutrient content such as protein, carbohydrates, fat, moisture, and ash content were determined according to the AOAC (2005) standard method, whereas macro minerals content (Na, K, Mg, Ca, and P) was carried out according to the AOAC method (2016) using Atomic Absorption Spectroscopy (AAS). The result showed that Cassidula had a protein content (57.02%) with the highest value compared to other types of nutrients. In addition, Cassidula also contained an essential macro mineral, such as calcium (37.0006 mg/kg) with the highest value followed by sodium (21.7364 mg/kg), respectively. The results showed that Cassidula can be used as an alternative food ingredient for human.

Abstract

Desa Sungai Nibung, Kubu Raya Regency, has been designated as one of the conservation areas in West Kalimantan. The coastal area of this village has potential of natural resources with a high level of diversity, including bivalves. Local community catch and sell bivalves for consumption. It is due to their high nutritional content, so that they are used by the local community as food and a source of protein. Inventory of biota is the first step to manage biological resources and support the management plan for a conservation area in this village. The study aimed to determine the diversity of bivalves in the coast of Desa Sungai Nibung, West Kalimantan. The research was conducted in December 2022. Sample collection was done using an exploratory method. Bivalves were taken, then stored in the cooling box for further identification. The result showed three bivalve species, such as Polymesoda erosa, Anadara granosa, and A. antiquata.
