Abstract

This time, this community service aims to develop the creativity of waste bank volunteers to utilize existing waste into valuable materials. Indeed, the volunteer team had previously been able to make trash into items that had selling value such as bags, table cloths and so on. However, based on the desire of the volunteer team to be able to contribute to education, the service team presented a solution so that they could use what was available as a learning medium. Some of these learning media are number chess and counting funnels. Number chess has benefits for teaching number ordering material, the concept of larger or smaller numbers, and training students to have a tenacious and persistent attitude. While the counting funnel can be used to teach multiplication and division material. The state of learning media is very important in mathematics because everyone knows that abstract learning can be conveyed contextually by the presence of a learning media. Community service has been carried out with lesson study, namely the planning stage, implementation stage, and reflection stage. At the planning stage the servant determines the day and steps for making the media. At the implementation stage, the service team accompanies volunteers in making learning media. Meanwhile, in the reflection stage, the waste bank service team and volunteers discussed the advantages, disadvantages, and economic value possessed by each media Pengabdian masyarakat kali ini memiliki tujuan untuk mengembangkan kreatifitas relawan bank sampah untuk memanfaatkan sampah yang ada menjadi bahan yang bernilai. Memang tim relawan sebelumnya telah mampu membuat sampah menjadi barang yang memiliki nilai jual seperti tas, tapalak meja dan sebagainya. Namun, berdasarkan keinginan tim relawan agar dapat berkontribusi dalam pendidikan, maka tim pengabdi mengahadirkan suatu solusi agar dapat memanfaatkan apa yang ada menjadi media pembelajaran. Beberapa media pembelajaran tersebut yaitu catur angka dan corong hitung. Catur angka memiliki manfaaat untuk mengajarkan materi pengurutan bilangan, konsep bilangan lebih besar atau lebih kecil, serta melatih siswa untuk memiliki sikap ulet dan tekun. Sedangkan corong hitung dapat digunakan untuk mengajarkan materi perkalian dan pembagian. Keadaan media pembelajaran sungguh sangat penting dalam matematika karena semua telah mengetahui bahwa pembelajaran yang bersifat abstrak dapat tersampaikan secara kontekstual dengan adanya suatu media pembelajaran. Pengabdian masyarakat telah dilaksanakan dengan lesson study yaitu tahap perencanaan, tahap pelaksanaan, dan tahap refleksi. Pada tahap perencanaan pengabdi menentukan hari dan langkah-langkah pembuatan media. Pada tahap pelaksanaan, tim pengabdi mendampingi relawan dalam pembuatan media pembelajaran. Sedangkan pada tahap refleksi tim pengabdi dan relawan bank sampah mendiskusikan akan kelebihan, kekurangan, serta nilai ekonomis yang dimiliki oleh setiap media.

Abstract

This study aims to improve students' mathematics learning outcomes of class VII G SMPN 48 Surabaya by applying the Tutor Sebaya method of learning. This research is a classroom action research (PTK). The subjects of the study were Class VII G SMPN 48 Surabaya, amounting to 38 students. The indicator of success in this study is determined by 70% of students complete learning. This research was conducted in two cycles with four stages of implementation, namely action planning, action implementation, observation or evaluation, and reflection. Data collection techniques of this study are tests, observations and documents. The results of this study indicate that the application of peer tutoring method on the subject of Algebra Shape can improve student learning outcomes of class VII G SMPN 48 Surabaya. This is shown in the improvement of the learning outcomes of each cycle that is on the pre-cycle result percentage of completeness of 23.68% has not reached the criteria of success, as well as in the first cycle of the completion percentage of 36.84% has not reached the criteria of success, as well as on the second cycle of the completion percentage of 71.05% has reached the expected success criteria. Â Keywords : Peer tutor method, the result of learning mathematics

Abstract

The purpose of this research is to 1) Knowing whether or not the influence of mastery of the concept of flat wake up to the ability to solve the problems of building the flat side space of students of grade VIII SMP Negeri 1 Kunjang, 2) Knowing there or not the influence of mastering the concept of algebra on the ability to solve the problems of building flatspace on the students of grade VIII SMP Negeri 1 Kunjang, 3) Knowing whether or not the influence of mastery of the concept of wake-up and algebraic concept of the ability to solve the problem of building the flat- side room of the class VIII SMP Negeri 1 Kunjang. This is acomparative causal study. Members of the population of 218 students. Technique of sampling technique of random sampling. Samples were taken about 13% of the total population of 42 students. Technique of collecting data using test method and method of documentation. Data analysis technique using multiple linear regression analysis. The results of the analysis together obtained Fhitung of 78.929> Ftabel=3.24 and Asymp probability value. Sig0,0000<a(0.05). This means there is asignificant influence between the mastery of the concept of wake-up and algebraic concept of the ability to solve the problem of building flat side space with the coefficient of determination of . Partially, the mastery of the concept of wake up to the ability to solve the problem of building the flat side space is shown by the result ofttes to btained thitung=11,029>ttable =2.02 and Asymp probability value. Sig is 0,0000 <a(0,05) with coefficient of determination . Mastery of algebraic concept on the ability to solve the problem of building flat side space is shown by ttest result obtained tcount= 8,793>ttable=2.02 and Asymp Sig value of 0,0000<a(0,05) with coefficient of determination.
