Malaria merupakan penyakit infeksi yang disebabkan oleh parasit Plasmodium yang ditularkan melalui nyamuk Anopheles betina. Untuk mencegah penyebaran malaria saat ini kita memerlukan keterlibatan dari masyarakat di setiap wilayah terjangkit secara aktif. Kegiatan pengabdian kepada masyarakat bertujuan untuk meningkatkan pemahaman masyarakat melalui edukasi sehingga masyarakat dapat mengimplementasikannya dikehidupan sehari-hari sebagai upaya untuk mencegah dan mengendalikan penyebaran parasite malaria di Kelurahan Tanjung Kasuari dan dilanjutkan dengan melakukan pemeriksaan laboratorium menggunakan RDT di akhir kegiatan. Metode pelaksanaan pengabdian yaitu memberikan edukasi tentang pencegahan dan pengendalian parasite plasmodium, pemeriksaan menggunakan metode POCT dengan alat rapid diagnostic test. Hasil pemeriksaan menunjukkan empat sampel dinyatakan positif terjangkit parasite plasmodium. Hasil evaluasi memperlihatkan dengan dilaksanakannya kegiatan pengabdian ini membawa pengaruh positif bagi masyarakat setempat. Kegiatan pengabdian ini sangat efektif membantu pengetahuan masyarakat tentang bahaya malaria
Abstract. This study discusses the influence of the scientific approach to mathematical learning outcomes. The type of research used in this writing is quasi-experimental, with scientific approach data collection on students' mathematical learning outcomes. Data analysis used with Simple Regression Analysis Test. Based on the analysis obtained by the results of the study, namely: the relationship or correlation between learning approaches with student learning outcomes with regression , with . The values for testing the data can use the Anova table and the significance level of 0.000 < 0.05. So that it can be said that the values of the two data are different. Thus, it can be concluded that there is the influence of the scientific approach to students' mathematical learning outcomes. This shows that the learning approach has a significant effect on students' mathematical learning outcomes. The coefficient of determination is means that the contribution or influence of the santifik approach (X) on the students' mathematical learning outcomes (Y) is . Thus, the scientific approach is better at contributing to students' mathematical learning outcomes.Keywords: Scientific Approach, Learning Outcomes
Abstract. Computers are essential tools for teaching, learning, and doing mathematics. Computers can visualize or represent mathematical ideas, organize and analyze data, and calculate effectively and accurately. Computers can help students conduct investigations through representations in various fields of mathematics such as geometry, calculus, statistics, algebra, measurements, and numbers. This paper discusses the role of Maple assisted representation in calculus learning. Representation is very supportive in increasing students' understanding of mathematical relations and concepts. There are three main functions of representation, namely complementing, constraining, and constructing. Complementing function is to complete the process and complete the information. The constraining function is to help students experience difficulties in a representation. The constructing function is to support constructing a deeper understanding of a concept. Students can get a deeper understanding if difficulties with only one representation. Maple software is a facility that is very supportive in making representations in learning mathematics as in calculus learning. By using Maple we can do numerical and symbolic calculations and perform graphical representations well. Maple can also effectively determine limits, derivatives, integrals, and a series of other functions and capabilities. With this Maple software capability, we can use it to improve students' understanding of calculus courses.Keywords: Representation, Computers, Maple, Calculus
Abstract. The purpose of this research is to know the understanding of mathematical concepts of students with the use of conceptual attainment model is better than the understanding of students' mathematical concepts with conventional learning. This research is quasi experimental research. The research design used was randomized subjects posttest only control group design. By selecting a Class VIII-2 sample as an experimental class and class VIII-1 as a control class of analytical techniques using the t-test as a hypothesis test, the prerequisite test is a normality test and homogeneity test. Based on the hypothesis test, t-test, obtained the price tarithmetic = 3.073 and price ttable = -1.997 at the real level of 0.05. Because tarithmetic > ttable, so Ha accepted and H0 rejected. So it can be concluded that the ability to understand the concept of mathematics students using conceptual learning model attainment better than the ability to understand the concept of mathematics students using conventional learning model.Keywords: Concept Attainment, Understanding of Concept
Communication skills focus on the importance of speaking, writing, describing and explaining mathematical concepts. In achieving that success is by using cooperative learning model. This model is an effective teaching strategy in improving student achievement and socialization while contributed to their changing of attitudes and perceptions of the importance of learning and cooperation, including for their understanding of their peers from different ethnic backgrounds. This research was conducted at SD IT Faza Azkia Kelurahan Hutaraja, South Tapanuli Regency, North Sumatera Province. This research uses quasi experimental research method. This study aims to describe how to improve students 'mathematical communication skills before and after using cooperative learning model, and also to know the effectiveness of using cooperative learning model in improving students' mathematical communication ability. Based on the results of the study concluded there is an increase in the mathematical communication skills of students before and after using cooperative learning model. And the cooperative learning model is effective for teaching count number operations. This is shown by: the effectiveness of student learning activities, the ability of teachers in managing learning is effective, students 'responses to learning is positive and mastery of students' mathematical communication skills reach 100%.
