Abstract

As part of the community environment, the school faces challenges in managing the growing amount of plastic waste. Through a project of making paving blocks from plastic waste, this study aims to help students learn geometry by integrating the concept of surface area of 3D shapes into real-life practice. Students took part in the project by designing and creating hexagonal prism-shaped paving blocks to cover the archery extracurricular area, which often gets muddy during rainy days. This study was conducted using a descriptive qualitative approach. Interviews with students and teachers, project process documentation, and observation of learning activities were all methods used to collect data. The results show that the Design Thinking approach supported students in understanding surface area in a more practical way, especially in calculating the dimensions and quantity of paving blocks needed. The project also encouraged students to be more aware of environmental issues.

Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan literasi matematis siswa Sekolah Satu Atap dalam menyelesaikan soal transformasi geometri, khususnya pada materi pencerminan. Metode penelitian yang digunakan adalah deskriptif kualitatif dengan subjek siswa kelas IX SMP Negeri 3 Satu Atap Tamanan tahun ajaran 2025/2026. Data dikumpulkan melalui tes kemampuan literasi matematis yang mengukur tiga aspek utama, yaitu formulate, employ, dan interpret. Hasil penelitian menunjukkan bahwa siswa hanya memahami konsep pencerminan secara visual dan intuitif tanpa mampu menerapkannya secara matematis. Total skor yang diperoleh siswa adalah 3 dari skor maksimum 8 dengan nilai kemampuan literasi matematis sebesar 37,5, sehingga tergolong kategori rendah. Kesalahan yang muncul mencakup ketidaktepatan dalam menentukan koordinat bayangan, kurangnya penerapan prosedur matematis, serta ketidakmampuan menginterpretasikan hasil dalam konteks simetri batik. Temuan ini menegaskan perlunya pembelajaran geometri yang lebih kontekstual dan berbasis literasi matematis agar siswa mampu mengaitkan konsep matematika dengan fenomena kehidupan nyata.

Abstract

This study aims to identify and describe in depth the emergence of conceptual misconceptions and procedural errors, as well as the dynamics of students' thinking processes when solving triangle geometry problems. The research used a descriptive qualitative approach with a case study design on three mathematics education students who had taken basic geometry, selected purposively to represent a variety of academic abilities and allow for intensive exploration of thought processes. The instrument is a triangular geometry problem solving task that looks for height, area, and lateral relations. Data was collected through written answer sheets, video recordings of the work, and retrospective clarification interviews, then analyzed qualitatively to trace patterns of misconceptions and procedural errors in the problem-solving flow. Data validity through source triangulation and trail auditing. The results showed that the three students displayed a neat calculation procedure, but were conceptually fragile. The height of a triangle is not interpreted as a perpendicular relation, the use of the theorem is carried out without prerequisites, and the relations between the lateral segments are assumed intuitively. Weak monitoring and evaluation during the problem-solving process hinders the formation of a coherent conceptual framework. These findings confirm the need for geometry learning that emphasizes the status of mathematical objects, adherence to the prerequisites of concepts and theorems, and the development of reflective monitoring habits in problem solving.
