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

Tengkuyung (Cerithidea obtuse) is one of the many snails that live in mangrove areas, being a source of food and the economy, especially for people in coastal areas. Land and sea development and transportation activities have the potential to become a source of Pb contamination in tengkuyung and its environment. This study aims to determine the concentration of lead metal (Pb) in sediments and tengkuyung in the Kuala mangrove area of Singkawang City. Sampling was carried out at two station points. Measurement of heavy metal lead (Pb) in sediments and tengkuyung was carried out using atomic absorption spectrophotometry (SAA) method. The results showed that the content of lead (Pb) in the sediment and tengkuyung at station 1 was 0.0914 µg/g and <0.0070 (µg/g), while at station 2 it was 0.3927 µg/g and <0.0070 (µg/g). The content of Pb metal in tengkuyung meat still meets the eligibility for consumption because it is below the threshold according to SNI no. 7387 in 2009, which is 0.5 mg/kg (0.5 ppm).
