Abstract

The study of effect of cooperative learning model of snowball throwing type in the molecule shape had been conducted. This study aims to find out the effect of cooperative learning model of snowball throwing on the student’s study outcome in molecule shape material science of SMA Negeri 1 Pasangkayu for 2013 neadenic year. The samples of study are grade XI Science 3 as experimental class (learning by using cooperative learning model of snowball throwing type) with 30 students and grade XI science 1 as a control class (convensional learning) 30 students. Data collection was conducted by using test instrument of study outcome in molecule shape material wich was validated before. The data analysis obtained average score in experimental class = 77.23 and for control class obtained average score 58.7. Based on the hypotesis analysis with t-test of statistic on the party was obtained the value of tcounted= 5.65 and ttable= 1.671 on a = 0.05. H1 was accepted and H0 was rejected, because tcounted was in area of rejection. This shows that the cooperative learning model of snowball throwing type gave positive effect on student study outcome in the molecule shape material in grade XI science of SMA Negeri 1 Pasangkayu.

Abstract

Lamtoro gung (leucaena leucocephala) is one of the food materials containing high enough protein which allow to be used as raw material for producing tempeh through fermentation. This study aimed to determine the effect of fermentation time to the protein levels of lamtoro gung seeds tempeh with variation fermentation times of 24, 36, 48, 60 and 72 hours. Steps in this study were sample preparation, producing lamtoro gung seeds tempeh,and protein levels analysis. The protein level was determined by Kjeldahl method. The results showed that there was an effect of fermentation time to the protein levels. The longer the fermentation time took effect to the lower the levels of protein produced. The highest protein level was obtained at 24 hours of fermentation time that was equal to 7.943%, while the protein level on fermentation time of 36 hours was equal to 7.725%, 48 hours fermentation time was equal to 7.195%, 60 hours fermentation time was equal to 7.197%, and 72 hours fermentation time was equal to 5.733%.

Abstract

The use of instructional media could help teachers to develop and deepen in teaching and learning process in the classroom. This study aims to determine the effect of using atomic structure card media and periodic systems toward learning outcome of the eleventh grade students of SMA Negeri 6 Palu. The population in this study was all of the eleventh grade students on Science Program of SMA Negeri 6 Palu in the academic year 2013/2014 which consists of 3 classes. The sample in this study was 30 students of Science Program 1 as the experimental class and 32 students of Science Program 2 as the control class. Testing research data used statistical analysis of the t test (right) with the prerequisite test, test for normality, and homogeneity. The data analysis result obtained for the average score in the experiment class X1 = 68.03 with deviation standard = 10.50 and the control class X2 = 54.75 with deviation standard = 9.57. Based on the testing result of hypothesis by statistical t-test values obtained right side of tcounted> ttable is 5.37 > 1.67 with a confidence level of 0.05 and degrees of freedom = 60. From the results of hypothesis testing, then, Ho was rejected so it can be concluded that there is a better influence in using atomic structure card media and periodic system toward learning outcome of the leventh grade students of SMA Negeri 6 Palu.

Abstract

Banana is a type of fruit that is relative widely consumed by community, either directly consumed or processed into other foods such as fried bananas and chips, while the peelsare usually thrown as waste. Banana peel is one source of pectin. Pectin is a polymer of D-galactaconic acid linked by an α-1,4-glycosidic bond. Pectin compounds are widely used in pharmaceutical, food, and beverage industries. This study aimed to determine pectin levels in banana peel and banana raja. This study was done by extraction method using HCl, added with 96% ethanol to filtrate to precipitate the pectin, then dried to obtain dry pectin. The solvent used was 0.05 N HCl (pH 1.5) with extraction temperature 90 for 80 minutes. The results showed that the extraction of banana kepok peel produced 12.243% pectin, while the extraction of banana raja peel produced 6.383% pectin.
