Abstract

The experiment purpose to find out fatty acid profil in catfish oil were used soybean oil with different level and to detect soybean oil concentrate in dietary hight produce catfish oil contens omega-3 fatty acid EPA and DHA. This research uses experimental methods and experimental design used completely randomized design (CRD) with five treatments , the percentage giving linolenic acid in the feed catfish at A = 0 % , B = 5 % , C = 10 % , D = 15 % , and E 20 % with each of the three replicates (15 experimental units) . Data were analyzed statistically is the content of EPA and DHA oils catfish at each treatment . Catfish oil extraction is done by wet rendering . How to wet rendering applied to fish that are high in fat and in large numbers . Further fatty acid content is determined based on the area that is formed using a Gas Chromatography . Soy bean oil as a source of linolenic acid in the diet had no effect on oil fatty acid profile catfish (Clarias sp) in terms of the aspect of the type of fatty acids , but in terms of aspects of the concentration of each type of soybean oil fatty acids influence . Changes in fatty acid levels to concentrations of soybean oil are generally not patterned , the pattern follows the curve of a parabola and hyperbole, at concentrations of 0%, 5% trend fatty acid concentration increased until optimal at concentrations of 10% and at a concentration of 15 % and 20 % trend of concentration fatty acids then declined. Soybean oil concentration in the feed oil producing catfish containing omega-3 fatty acids , EPA and DHA concentration is highest at 10 % . Generated at these concentrations of omega - 3 fatty acids 8.33%, 5.05% EPA and DHA of 1.14 % .

Abstract

The problem in this study was the lack of student activities and low learning outcomes of students in science subject at fourth grade SDN Kawatuna Palu. This study was classroom action research consist of two cycles. Each cycle consists of two meetings. The stages of every cycle were planning, action, observation and reflection. By through the six phases of Student Team Achievement Division (STAD) learning, that students activity and student learning outcomes on the material force and motion of objects might increase. The activity of student in first cycle reached 72.7%, (good categories according to Likert scale), teacher activity reached 75% (good categories) and learning outcomes in the form of classical completeness reached 59.4% (enough category). In the second cycle, the student activity reached 84.9% and teacher reached 87.5%, the result of classical completeness increased up to 100%. These results provide a positive impact in improving the activity and student learning outcomes. STAD might made students more familiar and more active in learning. Familiar means that students work together in completing the LKS group, they cooperate by accepting the differences of each member of the group. Active in this case was students more active to ask and answer the question, both of teachers and of other groups at the time of the learning process.

Abstract

Physics as a subject of the natural phenomenon is expected to be taught in a simplistic so the learning model and media are used by teachers greatly affect students' understanding of a concept. This study aimed to describe:(1) the effect of the initial capabilities of the students' understanding of concepts in a dynamic electrical material. (2) the effect of learning model for understanding the concept. (3) identify the interaction between the initial capabilities and learning model for understanding the concept. The population in this study were all students of class X of SMAN 8 Palu academic year 2013/2014, amounting to 103 students. Data collection techniques with a random sample, and the test in the form of multiple choice. The tests are given to measure students' understanding of physics concepts. Data analysis technique used was qualitative quai experiment with a 2x2 factorial design. The results showed that: (1) The initial capability significantly affect students' understanding of the concept. (2) the learning STAD significantly affect students' understanding of the concept. (3) there is no interaction between prior knowledge and understanding of the concept of students' learning model.
