Penelitian ini bertujuan untuk mengevaluasi dan mengoptimasi kinerja kolom light end stripper di PT X guna meningkatkan efisiensi energi dan pemisahan. Simulasi dilakukan menggunakan Aspen HYSYS dengan pendekatan optimasi energi melalui penurunan laju alir steam dan optimasi pemisahan melalui variasi reflux rate. Hasil simulasi menunjukkan bahwa kebutuhan panas reboiler untuk mempertahankan kemurnian 99,63% hanya sebesar 374.868,43 kJ/jam atau 24,53 kg/jam steam, dibandingkan kondisi aktual sebesar 10.168.709,92 kJ/jam atau 665,4 kg/jam steam, sehingga terjadi penghematan energi sebesar 96,31%. Optimasi pemisahan dengan peningkatan reflux rate hingga 14.000 kg/jam menghasilkan kemurnian propilena 99,8% dengan reboiler duty 5.219.207,95 kJ/jam dan juga penghematan energi 48.69% dibanding kondisi aktual. Temuan ini menunjukkan bahwa kolom memiliki potensi efisiensi signifikan, namun diperlukan verifikasi lapangan, inspeksi internal, serta uji bertahap pengurangan aliran steam sebelum penerapan penuh untuk memastikan hasil simulasi dapat diterapkan secara nyata di unit produksi PT X.
