Abstract

This study aims to describe the ability of students' mathematical representation on the material of a two-variable linear equation system reviewed from Self Efficacy. The type of research used is qualitative research with descriptive methods. The sampling technique used is purposive sampling. The data collection technique used a test of students' mathematical representation ability, self-efficacy questionnaire, semi-structured interviews, and documentation. The data obtained was then analyzed in 3 stages, namely data reduction, data presentation and conclusion drawn. The results showed that students with a high self-efficacy category met all three indicators of mathematical representation ability, namely using visual representations to solve problems, solving problems by involving mathematical expressions and writing Steps to solve mathematical problems with words. Students with the category of self-efficacy Moderate meet two indicators of mathematical representation ability, namely using visual representation to solve problems and solve problems by involving mathematical expressions. Students with low self-efficacy meet one indicator of mathematical representation ability, namely solving problems by involving mathematical expressions.

Abstract

Minimum competency assessment is a basic competency that all students need to be able to develop their own abilities and play an active role in society in positive activities. Minimum competency assessment aims to measure students' cognitive learning outcomes which include reading literacy and numeracy competencies. This study aims to determine the types of errors made by students in solving algebraic domain numeracy problems based on the kastolan theory, namely: (1) conceptual errors, (2) procedural errors, (3) technical errors. The research that has been conducted is a qualitative descriptive study with a research instrument of three AKM type algebra essay questions on 26 class VIII 3 students at SMP N 1 Tambusai. The results obtained based on the results of student answer sheets include: (1) conceptual errors of 30.76%, procedural errors of 38.46%, and technical errors of 32.05%. It can be concluded that the mistakes that students often make are procedural errors. The results of this study provide an overview of the various errors made by students in solving algebraic domain AKM problems, so that they can determine follow-up actions so that students' numeracy skills become better.

Abstract

Upaya peningkatan literasi marketing para pelaku UMKM dipandang penting untuk dilakukan. Salah satu strategi marketing dalam rangka menarik penjualan adalah pemberian diskon. Melalui peningkatan literasi tentang diskon dapat memberikan alternatif bagi penjual (pelaku UMKM) untuk meningkatkan minat konsumen. Literasi marketing yang diajarkan antara lain Waktu diskon, diskon sesuai nama, post and discount, diskon pengguna kartu kredit, diskon cashback, grup diskon, dan diskon member. Strategi yang digunakan dalam peningkatan literasi ini melalui ceramah, diskusi, dan tanya jawab. Hasil dari kegiatan pengabdian ini adalah bertambahnya wawasan pelaku UMKM Batik Citra Gendhis, Kabupaten Malang.

Abstract

Kelompok usaha pengrajin gula aren di desa Desa Rambah Tengah Hulu merupakan pengrajin gula aren skala rumah tangga yang memproduksi gula aren secara tradisional. Teknologi yang digunakan berasal dari teknologi turun temurun termasuk proses pengemasan produk dan belum memiliki label, PIRT, dan Nomor Izin Berusaha. Saat ini produk gula aren yang dihasilkan para pengrajin juga masih dalam satu bentuk produk saja yaitu gula aren berbentuk balok. Berdasarkan informasi dari pengrajin bahwa mereka belum memahami tentang cara membuat produk hasil gula aren selain dari gula aren cetak/balok, artinya para pengrajin memiliki keterbatasan pengetahuan tentang potensi pembuatan gula aren menjadi produk lainnya, misalkan gula semut. Untuk meningkatkan pendapatan para pengrajin gula aren maka perlu ditingkatkan nilai tambah dari gula aren itu sendiri, sehingga tujuan dari pengabdian ini adalah perbaikan kemasan dan diversifikasi gula aren menjadi gula semut. Metode pelaksanaan kegiatan adalah pertama-tama pengrajin diberi penyuluhan tentang pentingnya NIB dan PIRT serta cara pengurusannya, selanjutnya para pengrajin diberi pelatihan tentang teknik pembuatan gula semut dan cara pengoperasian alatnya. Hasil dari pelaksanaan kegiatan ini yaitu Rata-rata pemahaman mitra tentang pentingnya NIB dan PIRT serta cara pengurusannya sudah mencapai 88%. Selanjutnya sebanyak 100% mitra sudah mengetahui tentang gula semut, cara pembuatan gula semut dan tahapan pembuatan gula semut. Mitra sudah memiliki alat pembuatan gula semut.

Abstract

Twenty-first-century learning requires teachers, particularly prospective mathematics teachers, to possess strong mathematical literacy in order to guide students in understanding, applying, and interpreting mathematics in various real-life contexts. This study aimed to develop a valid and reliable mathematical literacy assessment instrument for prospective mathematics teachers by adopting the 4-D development model. The instrument focused on counting techniques and probability concepts, aligned with the AKM/IEA mathematical literacy cognitive levels of knowing, applying, and reasoning. The trial participants consisted of 64 undergraduate students enrolled in the mathematics education program at the second, third, and fourth-year levels. Content validity analysis using Aiken’s index indicated that all items were valid, with coefficients ranging from 0.80 to 0.95. Furthermore, construct validity testing through Confirmatory Factor Analysis (CFA) demonstrated adequate convergent validity, as indicated by an Average Variance Extracted (AVE) value of 0.581 and a composite reliability (ρc) value of 0.815. These findings indicate that the developed mathematical literacy assessment instrument meets validity and reliability criteria and is therefore suitable for use as an item bank in basic statistics courses or related subjects.
