Abstract

Dahlia variabilis is one of plant that commonly growing in highland hills in Indonesia. The preliminary screening on secondary metabolitesshowed that the presence of flavonoids, phenolics and saponin in methanol extract of this plant’s tuber. Its methanol extract was subjectedto the evaluation of non-specific parameter of extract standardization as well as antimicrobial assay using disc diffusion method againstEscherichia coli and Staphylococcus aureus. The result revealed that the methanol extract contained 25.48±1.63% of water content,4.06±0.15% of ash content, and there was no heavy metal contamination detected. Antibacterial activity assay of three differenceconcentrations of the extract (10; 8 and 2%) demonstrated that extract with 10% of concentration gave the strongest activity against twotested bacterium with diameter of inhibition of 8.67±0.57 and 8.33±0.28 mm against Escherichia coli and Staphylococcus aureus, respectively.

Abstract

The aims of this reasearch are to find out the influence of POE model through experiment and demonstration methods viewed by prior knowledge and generic science skill and the interaction of them to students’ cognitive, afective, and phsycomotor learning achievements on environment pollution subject. The population of this reseach was all students of the seventh grade of MTs PPMI Assalam Sukoharjo. The sample of this reseach was determined by using cluster random sampling and the result got two classes. Experiment class I (7C) used POE model with experiment method and experiment class II used POE model with demonstration method. Data collected technique used test to get students’ cognitive achievement, while observation sheets were used to get students’ affective and phsycomotor acievements, and test sheets were used to get students’ prior knowledge and generic science skill. Hypothesis was analyzed used ANAVA. The results of the research were as follow: There was influence of prior knowledge and generic science skill to the student cognitive achievement and also there was interaction between the POE model through experiment and demonstration methods, prior knowledge, and generic science skill to the students’ cognitive achievement.
