Abstract
Level Crude Palm Oil (CPO) di dalam tangki timbun merupakan salah satu variabel penting yang harus diatur dan dipantau. Tangki timbun didesain lengkap dengan sistem pemanas yang menyuplai steam dari boiler mengalir pada saluran pipa secara konstan. Proses pemanasan dimulai saat CPO mengisi tangki timbun. Proses ini diperlukan untuk memenuhi persyaratan temperatur (50oC), sehingga CPO dapat disalurkan ke pelanggan. Permasalahan terjadi ketika level CPO menurun karena valve keluaran dibuka yang menyebabkan temperatur meningkat. Volume CPO yang lebih kecil di dalam tangki timbun dengan aliran steam yang konstan akan menyebabkan kelebihan energi panas yang ditransfer dan temperatur meningkat. Dengan mengacu pada permasalahan tersebut, sistem pengaturan level CPO diperlukan untuk menjaga level CPO mendekati konstan dan temperatur yang diinginkan dapat tercapai. Dengan mengatur aliran yang masuk ke dalam tangki, level CPO juga dapat diatur. Pada sistem real, banyak faktor yang dapat menyebabkan parameter sistem berubah-ubah, sehingga kontroler PI MRAS harus dipilih untuk membangun suatu sistem adaptif. Dari hasil simulasi diperoleh bahwa sistem ini dapat menyesuaikan dengan referensi model dan lebih cepat beradaptasi ketika terjadi perubahan parameter.
========================================================
Crude Palm Oil (CPO) level inside of storage tank was a crucial variable that must be under controlled and monitored. A storage tank was designed completely with a heating system that supply the steam flowing on a pipeline constantly from the boiler. Heating process will be started while CPO fill the storage tank. This process is needed to satisfy the temperature requirement (50oC), so that the CPO can be distributed to the customer. The problem is occurred when the CPO level is going down by the output valve opened, that affect the temperature is getting higher. Lower CPO volume inside the storage tank with the constant steam flow heating will cause excess heat energy transferred and the temperature increased. According to that problem, a CPO level control system was required to keep the CPO level almost constant and the desired temperature can be achieved. By controlling the inlet flow, the CPO level also able to be controlled. In the real system, there are many factors that cause the system parameter changed, so that the PI MRAS controller must be selected to build an adaptive system. The simulation result show that these system can follow the reference model and adapt faster when the system parameter changed.
