The purpose of this research is to analyze the effect of Krulick Rudnick Heuristic Strategy based on ethnomathematics on student geometric representation skill (GRS). The research conductes at Junior High School in Jakarta in Academic Year 2018/2019. This research was quasi-experimental method with randomized posttest only control group, which is involve 27 students in experimental class and 25 students in control class that choosen by cluster random sampling technique. The data collecting for GRS used by using the test. The result of research revealed that student’s GRS taught by Krulick Rudnick’s Heuristic strategy based on ethnomathematics is higher than those taught by expository strategy. That skills include visual, symbolic, and verbal indicators. Ethnomatematics involved include culture of bamboo fishtrap (bubu), transplantation of coral reefs, mangrove conservation, processed fish food, fishing activities (manyang), tourist resorts, historic building, and food served in traditional traditions (sea parties). The conclusion of this show that the use of Krulik Rudnick heuristic strategy based on etnomathematics is more effective in enhanching students’ GRS compared with an expository strategy. (η2=0,102).

Abstract Cancer cases are increasing every year and the costs incurred for cancer treatment are getting bigger so there is a need to prevent cancer prevention, one of them is through IVA examination. Given the importance of examining IVA to detect early cervical cancer in an effort to reduce the incidence and death of cervical cancer. Knowledge is an important factor for generating early detection behaviours. One of the efforts is to increase community knowledge and interest by using counselling. This study uses a quantitative approach. The method used in this study is quasi-experimental or quasi-experimental. The design of this study used a randomized two-group design. This design aims to see the magnitude of the effect of treatment given to the experimental group given health education and the control group given leaflets. The population in this study were all 5,900 women of childbearing age (WUS) who had or had been married as much as 5,900 people. The sampling technique was done by cluster random sampling technique as many as 80 respondents consisting of 40 experimental samples and 40 control samples. The measuring instrument used in this study was a questionnaire to measure the knowledge and interest of mothers in conducting IVA examinations. The statistical test used in this study uses Independent T-Test. The result of the study is that there is a difference in WUS knowledge about cervical cancer in the group given Health Education and the group given the leaflet/brochure is indicated by the p-value of 0,000. There is a difference in the interest of WUS in examining the IVA in the group given Health Education and the group given the leaflet/brochure is indicated by the p-value of 0.000.     Keywords: Health Education, IVA Test, Interest  Abstrak Kasus penyakit kanker bertambah setiap tahun dan biaya yang ditanggung untuk pengobatan kanker semakin besar sehingga perlu adanya tiondakan pencegahan penyakit kanker salah sarunya melalui pemeriksaan IVA. Mengingat betapa pentingnya pemeriksaan IVA untuk mendeteksi dini untuk kanker serviks dalam upaya menurunkan insiden dan kematian akibat kanker serviks.

This study aims to know whether there is a correlation between students’ Quranic memorization and their English vocabulary retention. This study chose 28 of seventh graders at Islamic Junior High School Az-Zahra Lampung in 2018/2019 academic year as the sample by means of cluster random sampling technique. This study applied correlational research design. The documented data of Quranic memorization of learners and the English vocabulary preservation were collected from the test and then analyzed for hypothetical testing employing Pearson's Product Moment equation. The outcome of the hypothetical test shows that Sig. (value) was generated by the value of significance = 0.000 < α = 0.05. It means the acceptance of Ha and the rejection of H0. Furthermore, based on the r value interpretation table, it is known that the observed r is a high correlation as the value of observed r is 0.622 in the 0.600 – 0.800 level. It can therefore be inferred that there is a significant correlation between the Quranic memorization of learners and the acquisition of English vocabulary.

Science Material

Natural science material is abstract such as the solar system causing students to have difficulty understanding the material so visualization is needed to study it. Interactive learning media is needed so that abstract material becomes simpler and easier to understand, learning is interesting, and meaningful. The purpose of this study was to determine the effect of Lectora Inspire-based interactive science media on students' analytical skills. The type of research used is a quasi-experimental with pretest posttest nonequivalent control group design. The population used consisted of 6 classes with cluster random sampling sampling technique taken 2 classes, namely VII B as the experimental class and class VII E as the control class, each of which amounted to 30 students. The results of the analysis using the Independent Sample T-Test show that there is an influence of interactive science media based on Lectora inspire to improve students' analytical skills. Therefore, the use of interactive science media based on Lectora inspire can be used in learning to improve students' analytical skills.
