Abstract

Uncaria gambir is a member of Rubiaceae family. Information related to antioxidants and the use of this plant in the food and cosmetic industry has been widely reported. This study aims to determine the physicochemical properties, phytochemical content and antioxidant activity of herbal tea made from gambir claw, which was collected from the Pontianak City area of ​​West Kalimantan. Determination of physicochemical properties is based on measuring the parameters of pH, water content, ash content and organoleptic including taste, odor and color when dissolved in water. Phytochemical screening was carried out using specific reagents to determine the presence of flavonoid compounds, tannins, alkaloids and saponins. Antioxidant activity was determined using the free radical scavenging method 2,2-diphenyl-1-picrylhydrazyl (DPPH). From the results of the measurement of the physical and chemical properties of gambir claw herbal tea, the pH, ash content, moisture content and powder conditions met the requirements of SNI No 3836 of 2013, phytochemical screening showed positive results for flavonoid and tannin compounds, and antioxidant activity was obtained at 88,398 ppm, classified as a strong antioxidant.

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

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 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.
