This study aims to determine the species and density of sea urchins, as well as the relationship between their length and weight in seagrass ecosystems in the waters of Teluk Tomini, Pohuwato Regency, Gorontalo. The method used in this study is random sampling, where research stations are determined based on the presence of seagrass. Data collection was carried out in January 2022 at two locations, namely the villages of Bumbulan and Libuo, Paguat District, Pohuwato Regency, using a 4 × 25 m square transect method placed perpendicular to the coastline towards the sea. From this study, three (3) species were found, namely Diadema setosum, Diadema savignyi, and Echi-nothrix calamaris, with varying density values. The analysis showed that D. setosum is the species with the highest density value in both locations, namely 0.016 ind/m2 (Bumbulan) and 0.09 (Libuo). Furthermore, D. savignyi species with a density of 0.03 and 0.05 ind/m2, while E. calamaris was only found in Bumbulan with a density value of 0.02 ind/m2. The analysis of body length and weight showed a negative relationship for all species.","PeriodicalId":210626,"journal":{"name":"Jurnal Penelitian Sains","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129889479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prevention of DM complications could be avoided by using antihyperglycemic therapy. Thus, may increase the risk of adverse effects. The discovery of antihyperglycemic compounds from medicinal plants was carried out to avoid adverse effects. One of the medicinal plants that has antihyperglycemic potential is karamunting (Rhodomyrtus tomentosa (Aiton) Hassk). This study was aimed to examine the antihyperglycemic activity of karamunting leaf extract and the compounds present in the extract with the highest activity. Activity test was carried out in vivo using Wistar strain male white rats. Extraction was carried out by multilevel maceration using n-hexane, ethyl acetate, and 96% ethanol as solvents. There were 6 treatment groups, namely the normal group, positive control, negative control, n-hexane extract, ethyl acetate extract, and 96% ethanol extract. The positive control was glibenclamide and the negative control was 0.5% Na CMC. Identification of the compounds contained in the extract was carried out by phytochemical screening. Statistical data analysis using one way ANOVA. The results showed that 96% ethanol extract of karamunting leaves had the best activity in reducing blood glucose levels with a decrease of 40%. The statistical test results showed a significant difference between each treatment group (p<0.05). In 96% ethanol extract of karamunting leaves, flavonoids, phenols, tannins and saponins were identified.
