Abstract

Internal factors greatly affect the success of students’ learning. Identify the learning style can be used for grouping students in learning so that students can learn in a proper way, comfortable and positive. This study aims to: (1) Describe the differences in learning outcomes and students’ activity with problem solving approach between grouping based on learning styles and grouping not based on learning styles, (2) Describe the interaction effect of grouping based on learning styles in a problem solving approach with learning style of each students towards their learning outcomes and activity. Population of this study were the students of the grade XI IPA in SMAN 1 Dolo, and with purposive sampling technique, the samples taken were the students of the grade XI IPA 1 and XI IPA 2. Collecting data using a VAK (visual-auditory-kinesthetic) learning styles questionnaire, objective tests, and students’ activity observation sheet. This type of research is quasy experiment. Data were analyzed using two-way ANOVA test. Based on the results of data analysis can be concluded that: (1) There are differences in learning outcomes and students’ activity with problem solving approach between grouping based on learning styles and grouping not based on learning styles, (2) There are interactions of grouping based on learning styles in a problem solving approach with learning style of each students towards their learning outcomes, but there is no interaction of grouping based on learning styles in a problem solving approach with learning style of each students towards their activity.

Abstract

The aim of this study to observe the effect rearing time of Banggai cardinalfish were infected with Vibrio sp. from mortality rate and verify tissue’s abnormalities through histopathology test. Rearing time were 5, 10 and 15 days using a completely randomized design with three replications. Data processing is done by analysis of variance one-way ANOVA. Histology bacterial identification and data were analyzed descriptively. Research conducted at the Installation Building Fish Quarantine of Palu, Microbiology Laboratory of Palu and Histology Laboratory Fish Quarantine of Makassar in April to August 2015. Based on identification, found 8 bacteria of Vibrio sp were V. pelagius, V. damsela, V. carchariae, V. anguillarum, V. ordalii, V. parahaemolyticus, V. alginolyticus and V. aerogenes.

The analysis showed that the independent variables (Xi) jointly significant effect on the dependent variable (Y) levels of food insecurity Biromaru Sigi district area, this is indicated by the value of the F-count 3246.506> F-table sig 19.16. 2 tile Adstj2 0.000 R2 = 0.999 means a 99.9% value variation of the food security area (Y) can be explained by variable food availability (X1), food access (X2), and utilization of food (X3), and the remaining 0.1% described other models. Value variations in the level of food security region (Y) can be explained by variable food availability (X1), Access to food (X2), and Utilization of Food (X3), regression coefficient / elasticity of food availability (X1) = 0.103, Access to food (X2) = 0.942, Utilization of Food (X3) = 0.606. The results of the analysis of the relationship of food availability, food access and food utilization level of food security to the region shows the influence of both direct and indirect effect on food security in the sub district of Sigi Biromaru
