Abstract

The determination of Zinc Concentration (Zn) in seaweed (Eucheuma cotonii) from Kwandang sub district Ponelo beach by Atomic Absorption Spektrophotometriy Method. This is search aim to know the Zinc Concentration in seaweed (E. cotonii) from Kwandang sub district beach with Atomic Absorption Spectrofotometry Method. This process begins with destructed the sample which is clean from organic compounds. Based on the measurement of standard soluble of Zn got the calibration curve with linier equilibration Y = 0,3481 + 0,0766 X and the Zn concentration in sample from Kwandang sub district Gorontalo beach district is 1.862 mg/mL in 8,02 gram sample.

Abstract

The title of classroom action research is Improving the achievement of concep atom structure thought cooperativeThis research involves the students of class X4 SMA N 3 Gorontalo of in academic year 2008/2009. with cooperative learning model jigasaw type thats have purpose for increasing study result of students class X4 in subject of atom strukture.Based in classroom action prosedure, analysis and reflection on action hypothesis testing doing in a stage. And continuous that is on every ending activities from every cycle. 85 students who on observation paper minimal reach the nice category. The students achievement in cycle I, from 32 students there are 18 students who get more than (6,9), and 14 students get less that (6,9) with the average (6,74), while in the cycle II is improve where 32 students there are 28 students (87,5) get more than 6,9 and students get less than 6,9 with the average 8,0 and the average of applicapibility 82,75. Based on the students achievement in apply of cooperative learning model jigsaw type in structure atom can be improve the students achievement, so the hypothesis in this research is valid.

Abstract

This research is an Action Classrom Research that is held in SMAN I Limboto at Even Semester, 2008/2009 Academic Years. The subject of research is class XI IPA 3 which have 28 students that consist of 9 boys and 19 girls. The object of thisreserch is to increase the students achievement by using Type TAI (Tiem Accelerated Instruction) Cooperative Learning Style. This researchheld in 2 cycles that research is 85 % Student get up to 70 and the learning activities which are marked by using observation sheet minimally reach good category. The students achievement on the first cycle shows the classical absorptive power reaches 89,55% and the study completeness reaches 96.43% This achievement show that the usage of type TAI (Team Accelerated Instruction) Cooparative Learning Style could increase the Students Achievement.

Abstract

This research is a laboratory experiment, which intends to isolate and characterize chitosan of windu shrimps skin, which is cultivated in Gorontalo by using Fourier Transform Infra Red Spectrophotometer. The result of water analysis and degree, ash degree, and the degree of deasetilation, which were found were in accordance to standard parameter of chitosan which is required, that are 8%, 1,5% and 80,01%. The test of chitosan solubility characteristic was apparently in accordance with standard parameter of chitosan quality that is not soluble in water, concentrated NH3, Na2SO4 2%, slightly soluble in concentrated HCl, concentrated HNO3 and soluble in CH3COOH 1%.
