<![CDATA[Descriptive text writing is an essential competency in Indonesian language learning, requiring students to observe objects, develop ideas, select appropriate diction, and organize information coherently. However, many students still encounter difficulties in generating ideas and developing detailed descriptions. This study aimed to analyze the effectiveness of AI-assisted image media through Google Gemini in improving the descriptive text writing skills of eleventh-grade students at SMK Negeri 1 Kragilan. The study employed a quantitative approach using a pre-experimental method with a One Group Pretest-Posttest design. The sample consisted of 30 students from class XI TJKT selected through purposive sampling. Data were collected through descriptive writing tests administered before and after the treatment and were analyzed using descriptive statistics, the Shapiro–Wilk normality test, a Paired Sample t-Test, and N-Gain analysis. The results indicated that the use of AI-assisted image media was accompanied by an improvement in students’ descriptive writing skills. The mean score increased from 34.83 in the pretest to 83.60 in the posttest, with improvements observed across all assessment aspects, including content relevance, text structure, diction, spelling and punctuation, as well as coherence and creativity. The Paired Sample t-Test revealed a significant difference between the pretest and posttest scores (p < 0.001), while the N-Gain score of 0.75 was categorized as high. These findings suggest that AI-assisted image media has the potential to serve as an effective instructional medium for helping students generate ideas and compose descriptive texts more systematically. ABSTRAK Keterampilan menulis teks deskripsi merupakan salah satu kompetensi penting dalam pembelajaran Bahasa Indonesia yang menuntut kemampuan siswa mengamati objek, mengembangkan gagasan, memilih diksi yang tepat, serta menyusun tulisan secara runtut. Namun, banyak siswa masih mengalami kesulitan dalam menemukan ide dan mengembangkan deskripsi secara rinci. Penelitian ini bertujuan untuk menganalisis efektivitas penggunaan media gambar berbantuan Artificial Intelligence (AI) melalui Google Gemini dalam meningkatkan keterampilan menulis teks deskripsi siswa kelas XI SMK Negeri 1 Kragilan. Penelitian menggunakan pendekatan kuantitatif dengan metode pre-experimental dan desain One Group Pretest-Posttest. Sampel penelitian berjumlah 30 siswa kelas XI TJKT yang dipilih melalui teknik purposive sampling. Data dikumpulkan melalui tes menulis teks deskripsi sebelum dan sesudah perlakuan, kemudian dianalisis menggunakan statistik deskriptif, uji normalitas Shapiro–Wilk, Paired Sample t-Test, dan N-Gain. Hasil penelitian menunjukkan bahwa penggunaan media gambar berbantuan AI diikuti oleh peningkatan keterampilan menulis teks deskripsi siswa. Nilai rata-rata meningkat dari 34,83 pada pretest menjadi 83,60 pada posttest, disertai peningkatan pada seluruh aspek penilaian, yaitu kesesuaian isi, struktur teks, penggunaan diksi, ejaan dan tanda baca, serta keruntutan dan kreativitas tulisan. Hasil Paired Sample t-Test menunjukkan perbedaan yang signifikan antara skor pretest dan posttest (p < 0,001), sedangkan nilai N-Gain sebesar 0,75 berada pada kategori tinggi. Temuan ini menunjukkan bahwa media gambar berbantuan AI berpotensi menjadi alternatif media pembelajaran yang efektif untuk membantu siswa mengembangkan ide dan menyusun teks deskripsi secara lebih terarah.]]>
