Abstract This study aimed to reveal the difference of the basic ability of scientific work development between students who are teached using discovery learning and conventional learning. This study used quasy experiment with The Non Equivalent Pretest-Posttest Design. The subyek which are 58 VIII grade students in one of junior high school in Palu City are chosen with simple random sampling. Data were collected by observation sheets (check list) and were analyzed by normality, homogenity, and t-test using IBM SPSS Statistic 22 program. The result shows that the significance of Sig (2-tailed) is 0.00 < 0.005, which means that H0 is rejected and H1 was accepted. In addition, the data of the basic ability of scientific work development showed that the value for students teached by the discovery learning model is 58.28% and students teached by the conventional learning model is 47.13%, so it can be concluded that there is a significant difference on the basic ability of scientific work development between students who are teached using discovery learning and conventional learning in the material of sight and optical devices.

The Difference

The rough surface of a heat cured acrylic resin as a denture base can cause a pathogenic buildup of plaques and biofilms, so an effort to clean the denture base is needed. The available denture cleaning chemicals are proof of some disadvantages, so it is necessary to do research on alternative natural ingredients. Srikaya seed extract using ethanol 96% solvent has been shown to have antibacterial activity and with its various properties, so that it has the potential to become denture cleaning agents. Samples were made based on ADA No.17 specifications with 5 samples in each of the 6 treatment groups, sampling using Simple Random Sampling. Samples contaminated with S. mutans were soaked in srikaya seed extract 25%, 50%, 75%, 100%, 0.5% NaOCl and sterile aquadest. There was a significant difference (p <0.05) in each treatment group. There is an influence of the difference in concentration of srikaya seed extract on the growth of S. mutans bacteria on a heat cured acrylic base. Keywords: heat cured acrylic resin, S.mutans, srikaya seed extract, absorbance

The purpose of this research is to know and investigate the difference of students’ ability in doing social arithmetic and the implementation of contextual teaching and learning model in experimental class and students’ ability in doing social arithmetic that taught by applying tutor method in control class. This research is classified as a quasi-experimental design which is used pre and posttest control group design. The sample of this research was eight B grade students as experimental class and eight grade A students as a control class. This research took place at junior High School (SMP) Negeri 2 Gondang, Bojonegoro, East java. This research applied random sampling technique. The sum of subject of the research was about 56 students which consist of 28 students from control class and 28 students from experimental class. The result of the research shows that there is difference in implementation of two different learning models. The implementation of contextual teaching and learning model is better than tutor model. It can be proved from the mean score of posttest in experimental class. It was 75.89 while in control class was about 71.96. It can be said that there was significant difference about 3.93. It can be concluded that contextual teaching and learning  (CLT) model can improve students’ ability in doing social arithmetic better than tutor model.   Tujuan dari penelitian ini adalah untuk mengetahui perbedaan kemampuan siswa menyelesaikan soal aritmatika sosial dari implementasi model pembelajaran Contextual Teaching and Learningdi kelas eksperimen dibandingkan dengan kemampuan siswa menyelesaikan soal aritmatika sosial dengan model pembelajaran ceramah di kelas kontrol.

This Research Is Motivated By The Mathematical Value Of FPB and KPK material which is still below the KKM. This happens because in learning the teacher has not applied the model and media so that students' mathematical understanding is still lacking. This study aims to determine the effectiveness of the application of discovery learning model assisted by office board media to improve mathematical understanding of FPB and KPK material in grade IV SD Negeri Sendangmulyo 02.This type of research is quantitative research, with a pre-experimental research design in the form of One-Group. Pretest-Posttest. The population of this research is class IV SD Negeri Sendangmulyo 02, the sample taken by class IV B SD Negeri Sendangmulyo 02 with the number of students is 36, using the simple random sampling type Probability Sampling technique. In collecting data, researchers used several techniques including interviews, observation, documentation, and tests. The results showed that there were differences between the pretest and posttest scores. The average pretest score was 57.87 and the average posttest score was 76.62. This is evidenced by the calculation of the t test obtained ttable (2.030) and tcount (10.375). So tcount> ttable, meaning that Ho is rejected and Ha is accepted, and the percentage of students reaches 83%. This proves that the application of the discovery learning model assisted by office board media is effective in improving the mathematical understanding of FPB and KPK material in grade IV SD Negeri Sendangmulyo 02
