Kemampuan komunikasi matematis dan kesadaran pengentasan kemiskinan merupakan dua aspek yang diperlukan dalam mencapai tujuan sdg nomor 1. kenyataannya kemampuan komunikasi matematis dan kesadaran terhadap pengentasan kemiskinan siswa masih rendah. oleh karena itu dibutuhkan satu upaya yang mampu meningkatkan kemampuan komunikasi matematis dan kesadaran pengentasan kemiskinan siswa. salah satu solusinya yaitu menerapkan model problem based learning (pbl) konteks sedekah. tujuan penelitian adalah untuk mengetahui peningkatan komunikasi matematis, kesadaran terhadap pengentasan kemiskinan siswa setelah memperoleh pembelajaran pbl melalui konteks sedekah dengan pembelajaran konvensional serta untuk mengetahui interaksi antara model pembelajaran dengan level siswa terhadap peningkatan kemampuan komunikasi matematis dan kesadaran terhadap pengentasan kemiskinan siswa. pendekatan penelitian kuantitatif dengan jenis eksperimen, desain penelitian yaitu quasi experimental, pretest dan posttest control group design. populasi penelitian adalah seluruh siswa kelas x sman 3 banda aceh. sampel penelitian yaitu satu kelas eksperimen 37 siswa dan satu kelas kontrol 36 siswa yang dipilih secara random sampling. instrumen yang digunakan yaitu tes kemampuan komunikasi matematis dan angket kesadaran terhadap pengentasan kemiskinan. teknik analisis data menggunakan uji one way anova dan two way anova. hasil penelitian menunjukkan: 1) terdapat perbedaan peningkatan kemampuan komunikasi matematis dan kesadaran terhadap pengentasan kemiskinan siswa melalui pbl konteks sedekah dengan siswa melalui pembelajaran konvensional, 2) tidak terdapat interaksi antara model pembelajaran dan level siswa terhadap kemampuan komunikasi matematis dan kesadaran terhadap pengentasan kemiskinan siswa. guru dapat menggunakan model pbl konteks sedekah pada pembelajaran matematika khususnya materi eksponen untuk meningkatkan kemampuan komunikasi matematis dan kesadaran siswa terhadap pengentasan kemiskinan. kata kunci: kemampuan komunikasi matematis, no poverty, problem based learning, sedekah, sdgs.

Mathematical communication skills and awareness of poverty alleviation are two aspects necessary for achieving the goal of SDG number 1. In reality, students' mathematical communication skills and awareness of poverty alleviation remain low. Therefore, an effort is needed to improve students' mathematical communication skills and awareness of no poverty. One solution is to implement a Problem Based Learning (PBL) model within the context of sedekah. The purpose of this study is to determine the improvement in mathematical communication skills and awareness of poverty alleviation among students after receiving PBL instruction through the context of charity compared to conventional learning, as well as to investigate the interaction between the learning model and students' levels regarding the enhancement of mathematical communication skills and awareness of no poverty. This research adopts a quantitative approach with an experimental type, specifically a quasi-experimental design, using a pretest and posttest control group design. The population of the study consists of all grade X students at SMAN 3 Banda Aceh. The sample includes one experimental class with 37 students and one control class with 36 students, selected through random sampling. The instruments used are tests for mathematical communication skills and questionnaires on awareness of poverty alleviation. Data analysis techniques employ one-way ANOVA and two-way ANOVA. The results of the study show: 1) there is a difference in the improvement of mathematical communication skills and awareness of poverty alleviation among students taught through the PBL context of charity compared to those taught through conventional learning; 2) there is no interaction between the learning model and students' levels regarding mathematical communication skills and awareness of poverty alleviation. Teachers can utilize the PBL model in the context of sedekah in mathematics instruction, particularly for exponent topics, to enhance students' mathematical communication skills and their awareness of no poverty Keywords: Mathematical communication skills, No Poverty, Problem Based Learning, sedekah, SDGs.
