Indonesia has changed the national assessment of school students from the national exam (NE) to the minimum competency assessment (MCA) in 2021. In the minimum competency assessment, one of the student's abilities measured is numeracy skills. So that the valid, practical, and effective assessment instruments that evaluate students' numeracy skills are needed. This study described the feasibility of developing a numeracy test instrument for minimum competency assessments and described students' numeracy abilities. This research was development research. This research involved junior high school students with different mathematical abilities. The data were analyzed descriptively by collecting observations, tests and document analysis. This study showed that the development of test instruments could be used as a reference to measure students' numeracy skills. The test instrument was categorized as very feasible, valid and practical. The test results indicated that there was a potential effect on students' numeracy skills. In solving numeracy test questions, the potential effect of the test instrument on numeracy skills was 75.69%, with the emerging mathematical understanding ability of 80.22%, the ability to apply mathematics in problem-solving by 74.94%, and mathematical reasoning ability of 71.93 %.

Mathematics students with a reflective thinking tend to have self-confidence in solving mathematics easily. In recent years, however, there have not been the results of the researches that classify students' reflective thinking for solving non-routine questions of Analytical Geometry questions, in particular. The present research paper reveals the new classification of the students' reflective thinking for solving the problems. These are solving Analytical Geometry which can cause the students' confusion to apply their reflective thinking. The classification of the study comprises four components. It employed a descriptive-qualitative approach. The amounts of the subjects were 21 out of 140 students who used their reflective thinking for solving questions. The data collection consisted of test, observation, and in-depth interview. The data validation employed a method triangulation technique. The results of the study show there are three classification of reflective thinking, namely: assumptive, virtual, and connective. The three classifications differ in the way they deal with confusion. Meanwhile, the three classifications have similarities. The students tended to use all of the reflective thinking components although there were a few indicators that were not realized maximally. These were making a plan before solving the problems, using an efficient way, and relating among concepts. The factor is students play an inactive role or low active in reflective thinking. Moreover, they think that the most important thing is answering the questions correctly and they do not understand the purposes of the problem. Therefore, the students need to get the treatments.

Hidroponik adalah salah satu cara bercocok tanam yang inovatif untuk diterapkan masyarakat di masa sekarang. Proses penerapan hidroponik dilakukan dengan sangat sederhana dan tidak memerlukan banyak tempat. Selain itu, banyak keuntungan yang bisa didapatkan melalui bercocok tanam hidroponik. Di masa pandemi covid-19 ini, banyak masyarakat yang bekerja dari rumah sehingga banyak waktu luang yang dimiliki. Oleh sebab itu, dilakukan kegiatan Pengabdian kepada Masyarakat yaitu Pelatihan Workshop Hidroponik untuk masyarakat Desa Kasri Kabupaten Malang. Adanya pelatihan ini diharapkan dapat meningkatkan produktifitas msayarakat Kasri di masa pandemic Covid-19. Tema yang diusung adalah berhidroponik dengan memanfaatkan barang-barang bekas yang mudah ditemui di sekitar tempat tinggal seperti penggunaan botol plastik dan kain flannel bekas. Pelatihan workshop yang dilakukan tidak hanya  penyampaian materi saja, tetapi juga melakukan praktik hidroponik secara langsung dengan menggunakan teknik wick system. Proses praktik yang dilakukan mulai dari penyemaian hingga pembibitan. Kegiatan ini berhasil dilakukan diukur dari fakta peserta yang bergabung mampu membuat hidroponik dengan bahan dasar barang bekas. Adapun tindakan lanjutan dari program ini adalah menjadikan hidroponik sebagai komersil bisnis baru bagi masayarakat Kasri sehingga bisa meningkatkan perekonomian mereka. Abstract: Hydroponics is one of the innovative farming methods that society applies today. The process of applying hydroponics is very simple and does not require a lot of space. In addition, there are many benefits that can be obtained through hydroponic cultivation. During the Covid-19 pandemic, many people work from home so they have a lot of free time. Therefore, Community Service activities were carried out, namely Hydroponic Workshop Training for the people of Kasri Village, Malang Regency. This training is expected to increase the productivity of the Kasri community during the Covid-19 pandemic. The theme carried is hydroponic by utilizing used items that are easily found around the residence, such as the use of used plastic bottles and flannels. Workshop training is carried out not only in delivering material, but also conducting direct hydroponic practice using the wick system technique. The practical process is carried out from seeding to seeding. This activity was successfully carried out as measured by the fact that the participants who joined were able to make hydroponics using used materials as basic materials. The follow-up action of this program is to make hydroponics a new commercial business for the Kasri community so that they can improve their economy.

<p><strong>Abstract:</strong> This research aims to the mathematical communication of students who experience folding back when solving mathematical problems. The eight grade students of SMP Islam Syabilurrosyad Malang have participated here. Student with high communication going through folding back effectively and clearly following logic reasoning. Student with high communication could write folding back result rightly and consecutively. Student with medium communication going through folding back after intervention. Student with medium communication have communicated folding back result clearly and consecutively but still there were mistakes in the last solution.</p><strong>Abstrak:</strong><em> </em>Penelitian ini bertujuan untuk mendeskripsikan komunikasi matematis siswa yang mengalami <em>folding back </em>ketika menyelesaikan masalah matematika. Penelitian ini dilaksanakan di kelas VIII SMP Islam Syabilurrosyad kota Malang. Siswa dengan kemampuan tinggi mengomunikasikan <em>folding back</em>nya dengan efektif dan jelas disertai alasan logis. Subjek berkemampuan tinggi juga menuliskan respons hasil <em>folding back</em> nya dengan benar dan terurut. Subjek berkemampuan sedang mengalami <em>folding back</em> setelah adanya intervensi. Subjek mengomunikasikan hasil <em>folding back </em>dengan jelas dan terurut, namun masih terdapat kesalahan pada solusi akhir jawabannya.

<pre><strong>Abstract: </strong>This study aimed to describe the relational thinking of male and female visual students in solving mathematical problems. The method used is descriptive analysis. Subjects in this study were 1 male student and 1 female student who had visual learning style. The instruments consists a learning style questionnaires, test questions and interview guidelines. The results showed that visual male students who were able to see equal to (=) as relation symbol, could focus on the expression structure and could provide rationality the problem solving strategy. However, male visual students have not been able to focus on structure because students make computational errors. </pre><pre><strong></strong><strong>Abstrak:</strong> Penelitian ini bertujuan untuk mendeskripsikan berpikir relasional siswa visual laki-laki dan perempuan dalam menyelesaikan masalah matematika. Metode yang digunakan adalah analisis deskriptif. Subjek pada penelitian ini adalah satu siswa laki-laki dan satu siswa perempuan yang memilki gaya belajar visual. Instrumen berupa angket gaya belajar, soal tes, dan pedoman wawancara. Hasil penelitian menunjukkan siswa visual laki-laki maupun perempuan mampu melihat tanda sama dengan (=) sebagai simbol relasi, dapat fokus pada struktur ekspresi dan dapat memberikan rasionalitas penggunaan strategi penyelesaian masalah. Namun, siswa visual laki-laki belum mampu fokus pada struktur ekspresi karena siswa melakukan kesalahan komputasi.</pre>
