Abstract

Penelitian ini bertujuan untuk menganalisis jenis-jenis kesalahan berbahasa yang dilakukan oleh siswa SMP dan SMA, khususnya dalam penggunaan huruf kapital, kata baku, dan tanda baca (tanda tanya, tanda seru, titik, koma, tanda petik). Penelitian ini menggunakan metode kuantitatif dengan melibatkan 43 siswa/i SMP dan SMA dari berbagai sekolah dengan mengisi kuesioner melalui Google Form. Data dianalisis menggunakan analisis data deskriptif dengan mendesktipsikan data secara apa adanya dan mendeskripsikan setiap jawaban dari responden. Hasil penelitian ini menunjukkan bahwa mayoritas responden memiliki pemahaman yang cukup baik mengenai penggunaan tata bahasa dan tanda baca dalam bahasa Indonesia. Hal ini bisa dilihat dari rata-rata skor yang telah diperoleh serta dominan jawaban yang sudah sesuai dengan kaidah bahasa baku. Meskipun demikian, masih terdapat beberapa responden yang mengalami kekeliruan dalam pemilihan kata baku, pemisahan kata, sera penggunaan tanda baca yang tepat. Hal inii menunjukkan bahwa masih perlu dilakukan bimbingan lebih lanjut kepada peserta didik dalam memahami tata cara berbahasa Indonesia.

Abstract

This study aimed to develop and evaluate the validity, practicality, and effectiveness of KoMaCu (Funny Mathematics Comics) as a digital comic-based learning medium for probability topics among ninth-grade students at Imelda Private Junior High School, Medan. The study was motivated by students’ low motivation and achievement in mathematics due to predominantly conventional and monotonous instructional practices. KoMaCu was designed by integrating visual narratives with the Realistic Mathematics Education (RME) approach to promote contextual and meaningful learning. The study employed a Research and Development (R&D) methodology using the ADDIE model, encompassing analysis, design, development, implementation, and evaluation stages. Data were collected through expert validation sheets, student response questionnaires, and pre-test and post-test assessments. The participants consisted of 18 ninth-grade students. The validation results indicated that KoMaCu achieved a highly valid category in terms of content, language, and media design. Practicality testing yielded a feasibility score of 66%, indicating positive student responses. Furthermore, students’ learning outcomes improved substantially, with the mean score increasing from 13.3 in the pre-test to 40.5 in the post-test. These findings demonstrate that KoMaCu is valid, practical, and effective in enhancing students’ understanding and motivation in learning probability, thereby contributing to the development of innovative digital learning media in mathematics education.
