Abstract

This Community Service (PKM) aims to build a sustainable and creative learning environment at SMA Swasta Yapim Taruna Stabat. This program was motivated by the lack of students' creative activities and the dominance of gadget use that inhibits social interaction and innovation in learning. This PKM activity involves various programs, such as entrepreneurship, gadget-free days in class, library cleanliness, and reading corners (literacy corners). The PKM implementation method includes initial observation, preparation of work programs, and implementation of various activities that last for one month. The results of this activity show an increase in student creativity in utilizing available resources, increased awareness of the cleanliness of the school environment, and increased social interaction through literacy and entrepreneurial activities. In conclusion, this PKM activity succeeded in having a positive impact on the learning environment at SMA Swasta Yapim Taruna Stabat. Suggestions for the sustainability of this program are the need for further monitoring and mentoring so that the results achieved can continue to grow and provide long-term benefits for students and schools.

Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan komunikasi matematis dan kemampuan pemecahan masalah murid pada materi Sistem Persamaan Linear Dua Variabel (SPLDV) di kelas VIII SMP Swasta HKBP Sidorame Tahun Ajaran 2025/2026. Latar belakang penelitian ini adalah rendahnya keterampilan murid dalam mengomunikasikan ide matematis serta menyelesaikan permasalahan yang berkaitan dengan kehidupan sehari-hari.Jenis penelitian ini adalah deskriptif kualitatif dengan subjek 14 murid kelas VIII. Instrumen yang digunakan terdiri atas tes uraian kemampuan komunikasi matematis, tes pemecahan masalah, dan wawancara. Data dianalisis melalui uji validitas, reliabilitas, tingkat kesukaran, dan daya pembeda, kemudian disajikan secara deskriptif berdasarkan indikator yang ditetapkan.Hasil penelitian menunjukkan bahwa kemampuan komunikasi matematis murid berada pada kategori sedang, dengan 14,29% murid pada kategori tinggi, 57,14% pada kategori sedang, dan 28,57% pada kategori rendah. Pada aspek pemecahan masalah, diperoleh 21,43% murid berada pada kategori tinggi, 64,29% pada kategori sedang, dan 14,28% pada kategori rendah. Murid relatif mampu menyatakan ide matematis dalam bentuk visual maupun tulisan serta menyusun rencana penyelesaian, namun masih kesulitan dalam menafsirkan ide dan memeriksa kembali hasil jawabannya. Kesimpulan dari penelitian ini bahwa kemampuan komunikasi matematis dan pemecahan masalah murid tergolong sedang sehingga diperlukan strategi pembelajaran yang lebih variatif untuk meningkatkan kedua kemampuan tersebut

Abstract

This study aims to analyze students’ mathematical communication skills and problem-solving abilities on the topic of Systems of Linear Equations in Two Variables (SPLDV) in Grade VIII of SMP Swasta HKBP Sidorame in the Academic Year 2025/2026. The background of this research is the low level of students’ skills in communicating mathematical ideas and in solving problems related to real-life situations.This research is a descriptive qualitative study with 14 eighth-grade students as the subjects. The instruments used consisted of an essay test on mathematical communication skills, a problem-solving test, and interviews. The data were analyzed through validity testing, reliability testing, difficulty level, and discriminating power, and then presented descriptively based on the established indicators.The results of the study indicate that students’ mathematical communication skills fall into the medium category, with 14.29% of students in the high category, 57.14% in the medium category, and 28.57% in the low category. In terms of problem-solving skills, 21.43% of students were in the high category, 64.29% in the medium category, and 14.28% in the low category. Students were relatively able to express mathematical ideas in both visual and written forms and to develop a solution plan, but they still experienced difficulties in interpreting ideas and reviewing their answers. The study concludes that students’ mathematical communication and problem-solving skills are in the medium category, thus more varied learning strategies are needed to improve these two abilities.
