Aksi demonstrasi atau unjuk rasa merupakan salah satu fenomena di dunia nyata yang sering terjadi dan melibatkan berbagai kalangan, baik mahasiswa, buruh, maupun anggota suatu organisasi. Khususnya di Sumatera Barat, pada tanggal 23 dan 25 September 2019 telah terjadi demonstrasi polemik RUU di gedung DPRD Sumatera Barat yang melibatkan ribuan mahasiswa, aparat kepolisian, dan anggota DPRD Tingkat I.
Pada penelitian ini dibahas model matematika aksi demonstrasi mahasiswa. Model ini merujuk pada model Richardson. Model dianalisis kestabilannya melalui analisis kestabilan titik ekuilibrium. Kestabilan titik ekuilibrium ditentukan dari nilai eigen matriks koefisien yang diperoleh. Hasil analitik dikonfirmasi dengan hasil numerik. Parameter model yang digunakan pada simulasi numerik diperoleh dari data yang diolah berdasarkan kuisioner yang diambil dari responden. Berdasarkan hasil yang diperoleh dapat disimpulkan bahwa aksi demonstrasi yang terjadi berlangsung anarkis. Hal ini sesuai dengan kenyataan yang terjadi di lapangan bahwa aksi demonstrasi yang terjadi pada kasus demonstrasi polemik RUU di gedung DPRD Sumatera Barat tanggal 25 September 2019 merupakan demonstrasi anarkis.
