Abstract
Minyak kelapa sawit memiliki peran krusial sebagai penyumbang devisa negara melalui ekspor serta berkontribusi signifikan dalam industri minyak kelapa sawit dan kopra. Selama proses produksi, limbah, termasuk limbah cair, terbentuk dan memerlukan perhatian khusus untuk menjaga keberlanjutan lingkungan. Oleh karena itu, penerapan Instalasi Pengolahan Air Limbah (IPAL) yang efisien dan optimal dengan pendekatan pemodelan matematika menjadi penting. Penelitian ini mengevaluasi pengaruh Dissolve Oxygen (DO), variasi nilai Mixed Liquor Suspended Solids (MLSS) awal, dan Solid Retention Time (SRT) dalam sistem lumpur aktif terhadap kinerja dan waktu yang dibutuhkan untuk mencapai periode transien. Metode Rune-Kutta orde-4 diterapkan dalam penelitian ini. Hasil penelitian menunjukkan bahwa waktu untuk mencapai periode transien dipengaruhi oleh DO, MLSS awal, dan SRT di tangki aerasi. Hasil simulasi menunjukkan bahwa pilihan SRT terbaik untuk nilai awal MLSS 250 mg/l dan 500 mg/l adalah 24 hari. Sementara itu, kombinasi terbaik untuk sistem lumpur aktif di Industri `X` adalah MLSS sebesar 1000 mg/l dan SRT selama 16 hari, dengan periode transien tercapai lebih cepat pada hari ke-27,04.
============================================================
Palm oil has a crusial role as a contributor toa the country's foreign exchange through exports and contributes significantly to the palm oil and copra industries. During the production process, waste, including liquid waste, is formed and requires special attention to mantain environmental sustainability. Therefore, implementing an efficient and optimal Waste Water Treatment Plant (IPAL) using a mathematical modeling approach id important. This research evaluates the effect of initial Dissolve Oxygen (DO), variations in the value of Mixed Liquor Suspended Solids (MLSS), and Solid Retention Time (SRT) in the activated sludge system on the performance and time required to reach the transient period. The 4th order Runge-Kutta method was used in this research. The results showed that the time to reach the transient period was influenced by DO, initial MLSS, and SRT in the aeration tank. The simulation results show that the best SRT choice for initial MLSS values of 250 mg/l and 500 mg/l is 24 days. Meanwhile, the best combination for an activated sludge system in Industry `X` is MLSS of 1000 mg/l and SRT for 16 days, with the transient period reached sooner at day 27, 04.
