The aim of this study was to evaluate acute toxicity of methanol extract of Sargassum echinocarpum on male and female of mice (Mus musculus) strain BALB/c two month age. S. echinocarpum was obtained from Talango Island in April 2008. The powder of S. echinocarpum was macerated by methanol (1:3) at 4 °C for 3 x 24 hours, then concentrated, dried, and extracted. The extract was screened to observe the phytochemical compounds. For acute toxicity extracts was given orally and once on one hour before feeding. The dose treatments were 0; 625; 1250; 2500; and 5000 mg/kg body weight (BW). Parameters measured were phytochemical contain, body weight during the study, 50 percent of lethal doses, and histology score of liver and kidney. The phytochemical study showed that methanol extract of S. echinocarpum contained tannins, polyphenols, saponins, glycosides, and steroids. On 1250 mg/kg BW or more, methanol extract of S. echinocarpum inhibited the increasing of body weight on mice, but, until 5000 mg/kg BW, it did not cause mortality on mice. On 1250 mg/kg BW or more, methanol extracts caused necrosis on hepatocyt and tubulus.Key words: acute toxicity, methanol extract, Sargassum echinocarpum

The aim of this research is to determine students' mathematical numeracy literacy skills in matrix material in terms of the self-efficacy of class XI IPA 3 SMA Negeri 1 Simpang Hilir, totaling 28 students. Of the 28 students, they will be categorized based on each student's abilities. This research began by providing a self-efficacy questionnaire, a test of numeracy literacy skills, and interviews to categorize students' ability levels. After this, it was continued with analyzing and categorizing based on self-efficacy and level of numeracy literacy skills to determine the research subjects who would be interviewed by selecting 9 subjects. The results of the research concluded that students who have high self-efficacy meet 3 indicators, namely using various kinds of numbers and symbols related to basic mathematics to solve problems in various contexts of daily life, analyzing information displayed in various forms (graphs, tables, sections, diagrams, and so on), and interpret the results of the analysis to predict and make decisions. Students who have moderate self-efficacy meet 2 indicators, namely using various kinds of numbers and symbols related to basic mathematics to solve problems in various contexts of daily life, analyzing information displayed in various forms (graphs, tables, sections, diagrams, etc). Students who have low self-efficacy only meet 1 indicator, namely using a wide variety of numbers and symbols related to basic mathematics to solve problems in various contexts of daily life.
