Abstract

Soil Transmitted Helmiths (STH) infections is still a problem in many areas of the world, there are more than 1.5 billion people, or 2.4% of the world population is infected with intestinal worms that are transmitted through the soil. STH distribution in Indonesia includes all islands in Indonesia, where the prevalence is highest in Papua and North Sumatra with a prevalence of between 50% to 80%. One source of infection was water and mud used in the cultivation of vegetables. Contamination worms may occur especially on vegetables that propagate in the soil or close to the soil. This research is performed in an analytic study with cross sectional design. vegetables are included in the sample in this research was lettuce, leeks, cabbage, spinach, and mustard as many as 50 samples taken from traditional markets and modern markets in Medan city. From the results done, it is known that the highest positive results is in traditional markets as much as 10 vegetables or (40.0%) and the lowest positive results is in modern markets as much as 3 vegetables or (25.0%). Based on these results we can conclude that there are differences between traditional markets and modern markets as evidenced by the value of p in this comparison are p=0,035, So there are differences of Soil Transmitted helminths contamination in raw vegetables sold in traditional markets and modern markets

Abstract

Review text is a text that results from an analysis of various things. Analysis can take the form of books, novels, news, reports or fairy tales. The text provides responses or analyzes related to the setting, time, place, and characters in the text. Basically, the review text is a book review or summary. The purpose of this study was to improve the students' ability to write text reviews using the Concept Sentence learning model. This classroom action research activity was carried out in two cycles using data collection techniques, observation sheets and assessment sheets. The subjects of this study were students of class VIII-1 SMP Negeri 2 Tuhemberua in the even semester, totaling 26 students, with 15 boys and 11 girls. The results of this study indicate that there is an increase in the ability to write reviewed texts through the concept sentence learning model. Cycle I with an average value of 62.11 the lowest score is 50, the highest score is 80, while in the second cycle with an average value of 80 the lowest score is 75 the highest score is 90. Students who complete the first cycle are 9 people with an average percentage 34.6% while the students who completed the second cycle were 26 people with an average percentage of 100%. The results of student observations in the first cycle of the first meeting were 76.15% and the second meeting was 79.23%, whereas in the second cycle the first meeting was 85.38% and the second meeting was 93.46%. The results of observations on the performance of researchers in the first cycle of the first meeting were 57.89% and the second meeting was 72.36%, while the second cycle of the first meeting was 81.57% and the second meeting was 88.15%. Based on the results of the study, the researchers concluded that: using the Concept Sentence learning model can improve the ability to write review texts in class VIII-1 students of SMP Negeri 2 Tuhemberua in the Learning Year. Suggestions from these results, the researchers suggest that: 1) for students it is expected to be able to increase interest in writing review texts, 2) for teachers of SMP Negeri 2 Tuhemberua, this research can enrich the knowledge of teachers in the field of study in solving problems related to teacher efforts. in improving the skills of SMP Negeri 2 Tuhemberua.

Abstract

This research began with the problem of the low Mathematics learning outcomes of class VIII students of SMP Negeri 2 Mandrehe, West Nias Regency on the Pythagorean Theorem material, under the Minimum Completeness Criteria (KKM) of 67. Of the 27 total students, only 12 students reached the KKM, which is around 44%. . The purpose of this study was to improve the learning outcomes of eighth grade students of SMP Negeri 2 Mandrehe. This research is a classroom action research (CAR) which is carried out in two cycles. This research was conducted in class VIII of SMP Negeri 2 Mandrehe in the 2019/2020 school year. Based on the results of the discussion and analysis, it is concluded that the application of the problem based learning (PBL) model can improve student learning outcomes on the Pythagorean theorem material. The increase in teacher activity in the learning process is caused by the teacher using a problem based learning (PBL) learning model. Student learning outcomes have increased from cycle I to cycle II. Student learning outcomes before the action reached the KKM only 12 students with a classical average of 44%. Then in the first cycle, only 18 students reached the KKM with a classical average of 67%. Cycle II students who reach the KKM 25 students with a classical average of 93%
