ABSTRAK Penelitian ini bertujuan untuk mengetahui efektivitas model pembelajaran inkuiri terbimbing terhadap hasil belajar peserta didik kelas XI KIMIA 2 di SMAN 9 Makassar pada materi pokok asam basa. Metode yang digunakan dalam penelitian ini adalah metode pra eksperimen dengan desain penelitian one group pretest posttest. Subjek penelitian terdiri atas 25 siswa kelas XI KIMIA 2 SMAN 9 Makassar. Data dikumpulkan melalui pretest dan posttest dan dianalisis secara deskriptif dan inferensial. Hasil analisis statistik deskriptif menunjukkan rata-rata N-gain hasil belajar 0,72 yang berada pada kategori tinggi. Pengujian hipotesis dilakukan dengan menggunakan analisis statistik inferensial. Analisis statistic inferensial dilakukan dengan menggunakan Uji Wilcoxon Signed-Rank. Hasil analisis menunjukkan nilai Zhitung = 4,37 dan Ztabel = 1,65. Nilai Zhitung lebih besar daripada Ztabel sehingga H0 ditolak dan H1 diterima dan disimpulkan bahwa penggunaan model inkuiri terbimbing efektif terhadap hasil belajar peserta didik kelas XI KIMIA 2 di SMAN 9 makassar pada materi pokok asam basa. ABSTRACT This study aims to determine the effectiveness of the guided inquiry learning model on the learning outcomes of eleventh-grade chemistry students (Class XI KIMIA 2) at SMAN 9 Makassar on the subject matter of acids and bases. The method used in this study was a pre-experimental method with a one-group pretest-posttest research design. The research subjects consisted of 25 students from class XI KIMIA 2 at SMAN 9 Makassar. Data were collected through a pretest and posttest and analyzed descriptively and inferentially. The results of the descriptive statistical analysis showed that the average N-gain of learning outcomes was 0,72, which is in the high category. Hypothesis testing was conducted using inferential statistical analysis, specifically the Wilcoxon Signed-Rank Test. The analysis results Zcalculated value of 4,37 and Ztable value of 1,65. Since the Zcalcuated value is greater than the Ztable value, H0 is rejected and H1 is accepted. Thus, it can be concluded that the use of the guided inquiry model is effective on the learning outcomes of eleventh-grade chemistry students (Class XI KIMIA 2) at SMAN 9 Makassar on the subject matter of acids and bases..
