Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan model pembelajaran Group Investigation (GI) berbantuan media sosial X terhadap kemampuan menulis teks berita murid kelas XI SMK Jakarta 1. Penelitian ini dilatarbelakangi oleh perlunya penerapan model pembelajaran yang dapat meningkatkan keterlibatan murid dalam memperoleh, mengolah, dan mengembangkan informasi faktual menjadi teks berita. Penelitian ini menggunakan pendekatan kuantitatif dengan metode quasi experiment dan desain pretest-posttest Control Group Design. Sampel penelitian terdiri atas 60 murid kelas XI SMK Jakarta 1 yang terbagi menjadi 30 murid pada kelas eksperimen dan 30 murid pada kelas kontrol. Pengumpulan data dilakukan melalui tes menulis teks berita yang diberikan dalam bentuk pretest dan posttest. Kelas eksperimen diberikan perlakuan menggunakan model pembelajaran Group Investigation (GI) berbantuan media sosial X, sedangkan kelas kontrol diberikan pembelajaran konvensional. Data penelitian dianalisis menggunakan statistik deskriptif, uji normalitas, uji homogenitas, dan uji hipotesis dengan Independent Samples t-Test. Hasil penelitian menunjukkan bahwa rata-rata nilai pretest kelas eksperimen sebesar 74,47 meningkat menjadi 86,67 pada posttest. Hasil uji normalitas menunjukkan bahwa data pretest dan posttest pada kelas eksperimen dan kelas kontrol berdistribusi normal, sedangkan hasil uji homogenitas menunjukkan bahwa data memiliki varians yang homogen. Hasil uji hipotesis memperoleh nilai Sig. (2-tailed) < 0,001 dengan nilai thitung sebesar 11,452 dan ttabel sebesar 2,001. Karena thitung > ttabel dan nilai signifikansi < 0,05, H₀ ditolak dan H₁ diterima. Dengan demikian, dapat disimpulkan bahwa terdapat pengaruh yang signifikan dari penggunaan model pembelajaran Group Investigation (GI) berbantuan media sosial X terhadap kemampuan menulis teks berita murid kelas XI SMK Jakarta 1. Kata Kunci: Group Investigation, media sosial X, kemampuan menulis, teks berita. ***** This study aims to determine the effect of the Group Investigation (GI) learning model assisted by social media X on the news writing ability of eleventh-grade students at SMK Jakarta 1. This study was motivated by the need to implement a learning model that can increase students' involvement in obtaining, processing, and developing factual information into news texts. This research employed a quantitative approach using a quasi-experimental method with a Pretest-Posttest Control Group Design. The sample consisted of 60 eleventh-grade students at SMK Jakarta 1, with 30 students assigned to the experimental class and 30 students assigned to the control class. Data were collected through a news writing test administered in the form of a Pretest and a Posttest. The experimental class received treatment using the Group Investigation (GI) learning model assisted by social media X, while the control class received conventional instruction. The data were analyzed using descriptive statistics, a normality test, a homogeneity test, and hypothesis testing using an Independent Samples t-Test. The results showed that the mean Pretest score of the experimental class was 74.47, which increased to 86.67 in the Posttest. The normality test results indicated that the Pretest and Posttest data of both the experimental and control classes were normally distributed, while the homogeneity test indicated that the data had homogeneous variances. The hypothesis testing results obtained a Sig. (2-tailed) value of < 0.001, with a t-count of 11.452 and a t-table value of 2.001. Since the t-count was greater than the t-table and the significance value was less than 0.05, H₀ was rejected and H₁ was accepted. Therefore, it can be concluded that the use of the Group Investigation (GI) learning model assisted by social media X has a significant effect on the news writing ability of eleventh-grade students at SMK Jakarta 1. Keywords: Group Investigation, social media X, writing ability, news text.
