Abstract

The aim of this research is to find out the effectivness of problem solving approach, to increase students’ mathematics ability of multiplication. This research was implemented at SDN Guntur 04 Pagi Setiabudi South Jakarta, with 44 students as subject of research. This is an action research by using Kemmis and McTaggart model in three cycles. Each cycle consists of planing, acting, observing, and reflecting. The data was collected through the students’ mathematic ability of multiplication by test, and non test observation of implementation the problem solving approach by sheet of observation to teacher and students activities, transcript of activities and document analysis, interviews and the documentation. The implication of researched indicates that the usage of problem solving approach can make students more active based on their mental ages development. Teacher can develop innovative method to suit the needs of sudents, so that learning becomes dynamic and meaningful.Keywords: problem solving approach, mathematics ability of multiplication, action research.

Abstract

Dental caries is still a dental health problem in Indonesia. Fluoride, one of the dental caries prevention material, but its safety and the danger of fluorosis is still debated. Theobromine is an alkaloid compound contained in cocoa beans. Theobromine is believed to increase enamel microhardness with mineral changes in the enamel superficial layer. Objectives: To determine the influence of theobromine on the enamel surface microhardness. Methods: This study used 40 premolar tooth crown pieces that were embedded in epoxy resin. Furthermore specimens were randomly divided into 4 groups, which were control (distilled water), theobromine 100 mg/L (T100), theobromine 500 mg/L (T500) and theobromine 1000 mg/L (T1000). Specimens were immersed for 15 minutes and microhardness test was performed using Knoop microhardness tester. Results: Increasing enamel microhardness was observed after treatment with four different theobromine concentrations. The highest icreased of enamel microhardness was shown in T1000 group and difference compared to other groups were statistically significant (p<0.05). Conclusion: theobromine is a potential dental caries prevention material due to its effect in improving the microhardness of tooth enamel.
