<![CDATA[The aim of this research is to find out students‘ errors and the factors which cause students to make errors when they solve problems in Basic ComputerProgramming using Matlab. The methods used to collect the data aredocumentation, test, and interview. This is a qualitative and uses descriptive method. The subject of this research is 35 students of Mathe-matics Education Departement class of 2015B. Three students with low ability who made errors in their worksheet are chosen as the interview subject. The data validation test is conducted with triangulation technique. The result is that the students‘ errors are divided into three categories, i.e: the errors in understanding the concept, the procedure, and the final result. Based on the result of this research, it is concluded that 17.1% of the students made errors in understanding the concept, 46, 7% of the students made errors in the procedure, and 5, 7% made errors in the final result. The factors influencing the students‘ errors are lack of understanding in prerequisite materials and lack of practice in solving Basic Computer Programming problems.]]>

<![CDATA[abstract: Mathematics is a subject that is still considered difficult by some students. This is because, mathematics is always associated with calculations, formulas, and graphics. In addition there is material in mathematics that is abstract. So students must imagine something abstract in order to understand the material. For this reason, students need intermediaries who make it easy to understand something abstract. This intermediary is called learning media. Based on interviews with mathematics teachers at MTs Miftahul Ulum Ngembal and PGRI Tutur Islamic Middle School, the procurement of mathematics learning media is still lacking. The learning media used are worksheets. The appearance of worksheets is not very interesting and only contains a summary of material and questions, making students less motivated to learn worksheets. They study when the test will be held. This causes learning outcomes, especially mathematics is still low, with a KKM value of 6.5. Problems faced by MTs. Miftahul Ulum Ngembal and PGRI Tutur Islamic Middle School are: a) Lack of learning media that attracts students' attention. b) Lack of student learning motivation in learning mathematics, especially Linear Equation of One Variable. c) Student learning outcomes are low, namely with KKM 6.5. d) Lack of student understanding of algebra material, especially the system of linear equations of one variable. This is because this material is material that has just been received at the junior high school level. The solution offered is to provide Mathematics Comic Training for students of PGRI Tutur Islamic Middle School and MTs Mifathul Ulum Ngembal. This training aims to increase student learning motivation which will have an impact on student learning outcomes. This training will be held in 2 meetings so as not to disturb the learning and teaching process. In practice, students will be divided into groups. Each group will be given a mathematical comic that contains material about one variable linear equations and questions related to one variable linear equations.]]>

<![CDATA[Penelitian ini bertujuan untuk mendeskripsikan kemampuan komunikasi matematika tertulis dalam menyelesaikan masalah cerita pada materi lingkaran. Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kualitatif dengan jenis penelitian deskriptif. Penelitian dilaksanakan di kelas VIIA SMP PGRI 6 Malang yang berjumlah 28 siswa. Teknik pengumpulan data yang digunakan adalah tes dan wawancara. Analisis data dilakukan berdasarkan hasil tes dan wawancara mengacu pada kriteria keterampilan komunikasi matematis dengan menggunakan 6 tingkat keterampilan komunikasi tertulis dalam menyelesaikan masalah cerita. Hasil penelitian menunjukkan bahwa tingkat keterampilan komunikasi tertulis siswa kelas VIII A materi circle berada pada kategori rendah, hal ini terlihat dari persentase masing-masing level yang ada untuk level 0 dan level 1. Dalam kategori sedang. ada untuk level 2 dan untuk level 3. Di kategori tinggi ada untuk level 4 dan untuk level 5. Kemudian diambil tiga persentase terbesar dari setiap kategori, antara lain untuk kategori rendah di level 0, kategori sedang di level 2 dan kategori tinggi di level 4. This study aims to describe the ability of written mathematical communication in solving story problems on circle material. The approach used in this study is a qualitative approach to the type of descriptive research. The study was conducted in class VIIA SMP PGRI 6 Malang, with a total of 28 students. Data collection techniques used were tests and interviews. Data analysis was performed based on test results and interviews referring to the criteria of mathematical communication skills using 6 levels of written communication skills in solving story problems. The results showed that the level of written communication skills of students in class VIII A on the material circle was in the low category, this is evident from the percentage of each level that is there for level 0 and for level 1. In the medium category there is for level 2 and for level 3. In the high category there are for level 4 and for level 5. Then the three biggest percentages of each category are taken, among others for the low category at level 0, the medium category at level 2 and the high category at level 4.]]>

<![CDATA[The purpose of this dedication is to overcome the problems at SMP Al Inayah and Islamic Junior High School PGRI Tutur. The problem in both schools is the lack of learning media in the form of props or other innovative media. Students learn math more through direct explanation by teachers who are dominated by giving lectures. Considering the students' lack of understanding in the set matter it is necessary to hold a manipulative media training activity at SMP Al Inayah Purwosari and Islamic Junior High School PGRI Tutur on the set material. Students in this area desperately need a refresher related to instructional design, in order to develop their conceptual comprehension skills which leads to improving students' mathematics learning outcomes on the subject matter using Venn Smart Diagram media. Benefits of this devotion is the benefits gained among students obtaining learning with manipulative media that are rarely implemented so that students' understanding of the material set increases. Increased understanding of concepts and student learning outcomes in the set material that is marked with 90% of junior high school students Al Inayah and 88% of students of Islamic Junior High School PGRI Tutur can solve the problem set well. ]]>

<![CDATA[Students consider fractions to be complex material. The results of the dialogue on preliminary observations with a mathematics subject teacher at a junior high school in Malang showed that many students could not model problems in the form of mathematics. According to the Newman stage, this study aims to analyze students' mistakes in working on story questions about fractions. This type of research is descriptive qualitative research. A total of 23 students were given instruments in the form of 2 fraction test questions. Based on the test scores obtained, the students were categorized (high, medium, and low), and two subjects were selected for each category for the interview. They were checking the validity of the findings using the triangulation technique, namely, by comparing the results of direct observation, student test results, and interview data. Based on the research results, there were three biggest mistakes of the students: transformation errors, reading errors, and misunderstanding of the questions. Further research is recommended that students be given more story questions about solving fraction problems so that similar errors do not happen again]]>

<![CDATA[Proses produksi jamu tradisional dengan mesin manual memerlukan waktu yang relatif lama. Proses produksi yang lama akan menghasilkan produksi jamu yang sedikit dan juga resiko tumbuhnya bakteri. Tujuan dari pengabdian ini yaitu membuat mesin modifikasi jamu untuk meningkatkan produksi jamu. Pengabdi melalui kegiatan PKM (Program Kemitraan Masyarakat) menawarkan metode pada mitra antara lain diskusi, pelatihan dan pendampingan. Diskusi berguna untuk menggali kelemahan dan kelebihan mitra. Pelatihan dibantu ahli mesin terkait pengoperasian mesin modifikasi jamu dan perawatannya. Sedangkan pendampingan dilakukan pengabdi mulai dari penyediaan mesin modifikasi jamu sampai produksi jamu. Hasil pengabdian menunjukkan kegiatan berjalan dengan lancar dengan penjadwalan yang sudah disepakati pengabdi dan mitra. Selain itu mitra juga berpartisipasi aktif dalam kegiatan pengabdian PKM ini. Penggunaan mesin modifikasi jamu dapat meningkatkan produksi jamu mitra.]]>
