<![CDATA[Abstract: Improving chemistry learning outcomes for vocational students using ARIAS learning model. Objectives: This classroom action research was carried out to investigate students’ chemistry learning outcomes at vocational level through ARIAS learning model. Methods: The study was conducted in two cycles, each cycle consisting of two meetings. Findings: The mean score before the treatment (T0) was 66.89 with learning mastery percentage of 40.54%, then the mean score increased to 76.51 after teacher applied ARIAS learning model in cycle I (T1) with learning mastery percentage of 62.16%. The improvement of the mean score of students’ cognitive learning outcomes also occurred in the last cycle. The mean score of student cognitive test result was 84.09 with learning mastery percentage of 89.19%. Students also gave positive responses of learning process. Conclusion: It indicated that the ARIAS learning model was proven to be able to effectively improve student learning outcomes, especially in Chemistry subjects at the vocational level.Keywords: Classroom action research, ARIAS learning model, chemistry learning outcomes.Abstrak: Meningkatkan hasil belajar kimia siswa kejuruan melalui model pembelajaran ARIAS. Tujuan: Tujuan: Menginvestigasi hasil belajar peserta didik pada bidang kejuruan dengan menerapkan model pembelajaran ARIAS. Metode: Penelitian ini dilakukan dengan dua siklus, masing-masing siklus terdiri dari 2 pertemuan. Temuan: Rata-rata hasil belajar sebelum diberikan perlakukan (T0) adalah sebesar 66,89 dengan persentase ketuntasan belajar sebesar 40,54%, kemudian rata-rata skor hasil belajar meningkat menjadi 76,51 setelah guru menerapkan model pembelajaran ARIAS pada siklus pertama. Peningkatan rata-rata skor hasil belajar kognitif siswa juga terjadi pada siklus terakhir. Skor rata-rata hasil tes kognitif siswa adalah 84.09 dengan persentase ketuntasan belajar sebesar 89,19%. Siswa juga memberikan respon positif terhadap proses pembelajaran. Kesimpulan: Model pembelajaran ARIAS terbukti dapat secara efektif meningkatkan hasil belajar siswa, terutama dalam mata pelajaran Kimia di tingkat kejuruan.Kata kunci: Penelitian tindakan kelas, model pembelajaran ARIAS, hasil belajar kimia.DOI: http://dx.doi.org/10.23960/jpp.v8.i2.201813]]>
