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

The akar kuning plant (Arcangelisia flava L) from the Menispermaceae family is one of the Bajakah plant groups, which propagate among large trees and are commonly found in tropical forests in the West Kalimantan region. The purpose of this study was to determine the phytochemical compound and activity of anti-inflammatory from the akar kuning stem ethanol extract through the stabilization ability of the human red blood cell membrane (HRBC) in vitro. The akar kuning plant was taken from the forest of the Kapuas Hulu region, dried and mashed first and then extracted by maceration using the organic solvent ethanol. The ethanol extract obtained was concentrated using a rotary evaporatory, then a sample solution of akar kuning ethanol extract was made at several concentrations. Based on the results of phytochemical testing, this plant contained flavonoids, tannins, alkaloids and saponins. Anti-inflammatory activity testing using rabbit blood and using diclofenac sodium as a positive control. The measurement results showed the anti-inflammatory activity of the ethanol extract of the yellow root plant at concentrations of 50, 100, 150, 200 and 250 mg/mL were 28.77, 39.45, 57.53, , 62.80 and 75.50%, while the percentage of HRBC stabilization of the positive control was at the same concentration were 34.55, 46.34., 56.56, 69.88 and 87.33%.

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

The increase in side effects due to the use of chemical drugs encourages people to return to nature, utilize the plants around them in dealing with health problems. Red ginger (Z. officinale Var Rubrum) and elephant ginger (Z. officinale var Roscoe) have been used empirically in medicine especially to boost immunity. This study aims to determine the tonic activity of the ethanol extract of red ginger and elephant ginger in vivo using the natatary exhaustin method with white rats (Rattus norvegicus) as test animals. The natural fatigue method was based on the resistance of the test animals to swimming in water after being treated with ethanol extract of red ginger and elephant ginger rhizome at a dose of 70 mg/kg body weight, using Na-CMC solution as a blank and caffeine solution as a positive comparison. Based on research data testing the tonic activity of red ginger and elephant ginger extracts in vivo showed that the tonic activity of red ginger ethanol extract with the swimming endurance of the test animals was for 27.72 seconds, longer than the swimming endurance of the treated animals. with elephant ginger ethanol extract which is only 16.46 seconds.

Abstract

Micro minerals are a number of minerals that the body needs to carry out its functions normally, even if only in very small amounts. The high need for minerals to improve health, especially in handling stunting in children during the growth and development period, encourages the search for food sources that are cheap and easy to consume. Sipunculus nudus is a marine animal that lives immersed in sand where the waters are relatively fertile, and is often found in the East of South Sulawesi region. The aim of this research is to determine the micro mineral content of iron (Fe), zinc (Zn) and iodine (I) in the meat of S. nudus in Samboang waters. Fe and Zn were determined using an atomic absorption spectrophotometer, while iodine was determined using an HPLC instrument. The results showed that the S. nudus sample contained Fe and Zn of 221.43 ppm and 21 ppm respectively, and the mineral Iodine (I) was 14.11 ppm.
