Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memanfaatkan limbah plastik menjadi paving block sebagai upaya pemberdayaan dan peningkatan keterampilan anak pemulung di Kelurahan Terjun, Kota Medan. Kegiatan ini berbeda dari program PkM sejenis karena secara spesifik menyasar anak pemulung sebagai subjek utama pemberdayaan melalui pendekatan edukatif dan berkelanjutan. Metode yang digunakan meliputi sosialisasi lingkungan, pelatihan teknis pembuatan paving block, serta pendampingan praktik berbasis learning by doing. Kegiatan ini melibatkan 15 anak pemulung, dengan hasil berupa peningkatan keterampilan teknis pengolahan limbah plastik dan produksi 45 unit paving block. Selain capaian teknis, program ini juga berdampak pada peningkatan kesadaran lingkungan, kepercayaan diri, dan sikap positif terhadap pembelajaran produktif. Kegiatan ini menunjukkan bahwa pengolahan limbah plastik berbasis teknologi tepat guna dapat menjadi sarana edukatif dan pemberdayaan sosial bagi anak pemulung.

Abstract

This study aims to conduct a diagnostic analysis of students by mapping their numeracy literacy (NL) and Mathematical Habits of Mind (MHOM) profiles, as well as examining the relationship between the two in solving non-routine problems. A mixed methods approach with a cross-sectional diagnostic design was employed, involving 120 elementary school students from three schools. Data were collected through a numeracy literacy diagnostic test, an MHOM questionnaire, structured observations, and in-depth interviews. The results indicate that students’ numeracy literacy ability falls into the moderately low category, with an average mastery percentage of 46.13%. The main weakness was found in the interpreting process, with a mastery percentage of 34.45%, while students showed relatively better performance in the applying process. The MHOM profile was in the moderate category, with relatively high scores in perseverance and working accurately, but low scores in seeking patterns and flexible thinking. The correlation analysis revealed a significant positive relationship between overall numeracy literacy and Mathematical Habits of Mind (r = 0.582, p < .001). Qualitative findings further showed that students with weak flexible thinking tended to repeat ineffective procedures when facing unfamiliar or non-routine problems. These findings indicate that students’ numeracy literacy difficulties are not only related to content mastery but also to dispositional barriers, particularly limited flexible thinking. This study contributes by providing a diagnostic mapping that links numeracy literacy difficulties with students’ Mathematical Habits of Mind. The findings suggest that instructional interventions should strengthen flexible thinking and pattern seeking to support students’ functional numeracy literacy.
