KOMUNIKASI MATEMATIS
%X Penelitian ini merupakan penelitian pengembangan yang bertujuan untuk
menghasilkan LKPD berbasis pendekatan Realistic Mathematic Education (RME)
yang memenuhi kriteria valid, praktis dan efektif dalam meningkatkan kemampuan
komunikasi matematis. Penelitian dan pengembangan mengacu kepada langkahlangkah model pengembangan 4-D terdiri 4 tahapan utama yaitu: Pendefinisian
(Define), Perencanaan (Design), Pengembangan (Develop), Penyebaran
(Disseminate). Penelitian dilakukan di SMAN 2 Natar kelas X Semester genap tahun
pelajaran 2022/2023. Deskripsi penelitian pengembangan yang digunakan adalah
pre-post control group design. Teknik pengumpulan data pada penelitian ini meliputi
wawancara, observasi, lembar angket, dan tes kemampuan komunikasi matematis.
Teknik analisis yang digunakan adalah statistik deskripsi dan uji-t. Berdasarkan
analisis data hasil validasi ahli media dan materi didapat rerata 84,6% dan 89,85%
dengan kriteria sangat valid, serta tanggapan guru dan siswa tentang kepraktisan
LKPD berbasis RME diperoleh skor 93,2% dan 90,65% dengan kriteria sangat
praktis. Berdasarkan hasil uji-t terhadap peningkatan (N-gain) kemampuan
komunikasi matematis 0.00001 < 0.005, sehingga LKPD berbasis Realistic
Mathematic Education (RME) efektif meningkatkan kemampuan komunikasi
matematis. Jadi dapat disimpulkan bahawa LKPD berbasis Realistic Mathematic
Education (RME) memenuhi kritria valid, praktis dan efektif untuk meningkatkan
kemampuan komunikasi matematis.
Kata Kunci: Lembar Kerja Peserta Didik (LKPD), Pendekatan RME, Kemampuan
Komunikasi Matematis.

This research is a development research that aims to LKPD products based on the
Realistic Mathematical Education (RME) approach that meet valid, practical and
effective criteria in improving mathematical communication skills. Research and
development refers to the steps of the 4-D development model consisting of 4 main
stages, namely: Define, Design, Develop, Disseminate. The research was conducted
at SMAN 2 Natar class X even semester of the 2022/2023 academic year. The
description of the development research used was the pre-post control group design.
Data collection techniques in this study included interviews, observation,
questionnaires, and tests of mathematical communication skills. The analysis
technique used is descriptive statistics and t-test. Based on the analysis of data from
media and material expert validation results, the average value was 84.6% and
89.85% with very valid criteria, as well as teacher and student responses regarding
the practicality of RME-based LKPD obtained scores of 93.2% and 90.65% with
very practical criteria. Based on the results of the t-test on increasing (N-gain)
mathematical communication skills 0.00001 <0.005, so that LKPD based on
Realistic Mathematics Education (RME) is effective in improving mathematical
communication skills. So it can be concluded that LKPD based on Realistic
Mathematics Education (RME) meets valid, practical and effective criteria for
improving mathematical communication skills.
