Abstract

The purpose of this study was to describe students' mathematical literacy abilities based on the level of mathematical connection ability using a qualitative descriptive approach. The researcher as the main instrument was assisted by test questions to measure the ability to connect mathematics and mathematical literacy, as well as interviews. The research subjects were 3 class IX students of SMP Islam Pakis. Subject selection was made based on high, medium, and low levels of mathematical connection ability. The results showed: The selection of research subjects was carried out by purposive sampling technique based on high, medium, and low levels of mathematical connection ability. The results of the data analysis obtained: (1) students at a high level of mathematical connection succeeded in achieving all indicators of mathematical literacy ability, such as being able to identify the information contained in the problem, make mathematical models, do reasoning, use symbols, design and implement appropriate problem strategies, summarizing the results, as well as conducting evaluations; (2) students who are categorized in the moderate level of mathematical connection ability are able to achieve five of the seven indicator components contained in mathematical literacy ability; (3) students who belong to a low level of mathematical connection ability are only able to achieve three of the seven indicator components needed in literacy skills.

Abstract

Trigonometry is a fundamental competency that holds particular importance for vocational students, as it is widely applied in fields such as engineering, design, architecture, and other practical domains. However, many vocational students still encounter difficulties, particularly in visualizing right-angled triangles in non-standard orientations, which hinders their understanding of trigonometric ratios. This study is a development research that produced an interactive visual application called AVIGO. The application provides concise learning materials, exercises involving right-angled triangles in both standard and non-standard positions, and contextual problems relevant to daily life. The findings of this study offer recommendations for mathematics education practitioners regarding the use of AVIGO as a learning medium to enhance students’ comprehension of trigonometric ratios. Furthermore, AVIGO is expected to foster students’ motivation to engage actively in learning trigonometry, thereby supporting the improvement of their conceptual understanding.

Abstract

Numerasi merupakan keterampilan dasar yang penting dikembangkan sejak usia dini karena menjadi fondasi bagi kemampuan berpikir logis, pemecahan masalah, dan kesiapan anak memahami konsep matematika yang lebih kompleks. Namun, guru RA Tazakka Kota Malang menghadapi berbagai kendala dalam menyusun dan mengimplementasikan program pembelajaran numerasi, seperti keterbatasan pemahaman konsep, kreativitas, media pembelajaran, serta ketidaksesuaian dengan kurikulum. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan kompetensi guru RA melalui pelatihan penyusunan program penguatan numerasi yang kreatif, interaktif, dan relevan dengan tahap perkembangan anak. Metode pelaksanaan meliputi observasi kebutuhan mitra, pelatihan konseptual dan praktik pembuatan alat peraga, simulasi penyusunan program, serta evaluasi melalui pre-test, post-test, dan kuesioner kepuasan. Hasil kegiatan menunjukkan adanya peningkatan pemahaman guru pada seluruh indikator, dengan persentase peningkatan antara 26,7% hingga 50%, terutama pada kemampuan menilai perkembangan numerasi anak dan pemanfaatan media interaktif. Seluruh peserta juga menyatakan kepuasan yang tinggi terhadap kegiatan ini dan merasakan manfaat nyata dalam merancang pembelajaran numerasi. Program pelatihan ini terbukti efektif dalam memperkuat kompetensi guru RA Tazakka dan dapat direplikasi di lembaga PAUD lain untuk mendukung penguatan numerasi sejak dini.

Abstract

Kampung Wisata Ekologis Puspa Jagad, sebagai destinasi yang mengedepankan pendidikan ekologis dan budaya, saat ini menghadapi tantangan dalam menyampaikan materi edukatif dan informasi secara efektif akibat keterbatasan peralatan, khususnya kekurangan LCD proyektor. Polinema melalui kegiatan Pengabdian Pada Masyarakat (PPM) hadir membantu memberikan solusi atas permasalahan mitra. Kegiatan yang dilaksanakan berupa pelatihan pengoperasian sistem proyeksi digital dan diikuti dengan penyerahan seperangkat alat pendukung berupa LCD proyektor dan layar proyektor tripod. Pelatihan mencakup cara mengoperasikan LCD proyektor sesuai tipe dan fiturnya. Hasil kuisioner menunjukkan bahwa seluruh responden (100%) sangat setuju terhadap semua aspek pelaksanaan kegiatan PPM di Kawasan Wisata Ekologis Puspa Jagad. Hal ini menegaskan bahwa program PPM dirancang sesuai kebutuhan, memberikan solusi efektif, serta meningkatkan pengetahuan, keterampilan, dan kemandirian mitra dalam mengelola destinasi wisata. Tim PPM juga dinilai responsif dan pendampingannya dianggap memadai.
