CV. Barsya Eka Plastindo merupakan perusahaan manufaktur yang bergerak dalam bidang daur ulang plastik. Pada proses produksinya memiliki dua area dalam pabrik, yaitu area produksi pertama dan area produksi kedua. Penelitian ini fokus ke salah satu area produksi karena memiliki proses yang sama. Permasalahan yang diakibatkan beban kerja tidak merata berdampak pada tingkat efisiensi dan produktivitas kerja yang kurang optimal. Penelitian ini bertujuan mengoptimalkan keseimbangan lintasan produksi berdasarkan beban kerja masing-masing operator. Metode pengambilan data dengan melakukan pengukuran secara langsung pada seluruh elemen kerja pada operator menggunakan stopwatch. Penelitian ini menggunakan metode Ranked Positional Weight (RPW) untuk menentukan alokasi beban kerja dari setiap operator. Hasil penelitian menunjukkan jumlah operator yang ideal untuk produksi daur ulang plastik sebanyak 4 operator dari jumlah semula sebanyak 6 operator. Pemerataan beban kerja dapat meningkatkan nilai efisiensi dari 53% menjadi 80,1 %. Peningkatan efisiensi lini ini disebabkan efektivitas elemen kerja/gerak masing-masing operator kerja. Peningkatan efesiensi lini, berdampak penurunan Balance Delay (BD) dari 47 %, menjadi 19,9 % dan Smoothing Index (SI) dari 78,58 detik menjadi 22,58 detik.
