Abstract

Inorganic waste is waste that is difficult to decompose, for example, plastic snacks, plastic bags, plastic/glass bottles, etc. Handling inorganic waste requires attention because wise methods are needed to manage and recycle inorganic waste properly. Because in reality, inorganic waste is the largest waste produced by humans. This can be seen from the accumulation of plastic waste around humans. Therefore, this activity aims to provide students with direct knowledge of how to process inorganic waste into valuable products. The method used in this journal is a qualitative descriptive method. This activity was carried out in class VIII I of SMP Negeri 7 Mstaram starting from 2 – 26 October 2023. The total number of students in this class is 40 students. The method of implementing this activity includes several stages, namely the problem identification stage, the action planning stage, the action implementation stage, and the final stage is turning around the results and actions. The products produced from processing this inorganic waste are handicrafts such as pencil cases, flower vases, pots, cars, and so on. Then the students' handicrafts were packaged and displayed. It is hoped that this activity can continue to be carried out and developed by the school to improve the quality of learning and improve student performance in processing and utilizing inorganic waste effectively and efficiently.

Abstract

Tujuan dalam penelitian ini adalah untuk mengetahui keefektifan model Problem Based Learning (PBL) terhadap Kemampuan Pemecahan Masalah Matematis siswa. Penelitian ini merupakan penelitian eksperimen semu dengan pendekatan kuantitatif. Populasi dalam penelitian ini adalah siswa kelas IX SMPN 16 Mataram dimana sampel diambil menggunakan teknik cluster random sampling dengan subjek penelitian adalah kelas IX A sebagai kelas eksperimen dan kelas IX B sebagai kelas kontrol pada tahun ajaran 2024/2025. Instrumen dalam penelitian ini berupa tes, lembar observasi dan pedoman wawancara. Teknik analisis data yang digunakan adalah teknik analisis deskriptif dan inferensial. Hasil perhitungan statistik uji independent sample t-test menunjukkan bahwa nilai   yaitu nilai nilai 2,002 dengan taraf signifikansi yaitu  yang menunjukkan bahwa  ditolak dan  diterima. Hal ini berarti terdapat perbedaan rata-rata kemampuan pemecahan masalah siswa kelas eksperimen dan kelas kontrol seperti nilai rata-rata kemampuan pemecahan masalah siswa kelas eksperimen lebih tinggi dibandingkan siswa kelas kontrol. Hal ini berarti penggunaan model PBL lebih efektif terhadap kemampuan pemecahan masalah siswa. Maka dapat disimpulkan bahwa penerapan model PBL efektif terhadap peningkatan kemampuan pemecahan masalah matematis pada siswa kelas IX SMPN 16 Mataram tahun ajaran 2024/2025.
