Abstract
Mikroalga adalah mikroorganisme uniseluler yang memiliki potensi besar sebagai produsen biomassa di masa depan, karena mampu mengandung lipid dalam jumlah yang tinggi walaupun dengan kondisi kekurangan nitrogen sekaligus mengonsumsi CO2 industri. Pertumbuhan mikroalga sangat berperan penting dalam produksi biomassa yang lebih banyak. Intensitas cahaya adalah salah satu faktor yang mempengaruhi pertumbuhannya sehingga dapat diatur intensitas cahaya yang masuk untuk memaksimalkan hasil biomassa. Kemudian dilakukan pengendalian optimal pada intensitas cahaya menggunakan Prinsip Minimum Pontryagin. Dalam Tugas Akhir ini menunjukkan peningkatan jumlah biomassa dalam waktu 2 pada kondisi awal (s,q,x)=(20,10,1.825) dengan proporsi c=42 dan kondisi awal (s,q,x)=(25,15,2.825) dengan proporsi c=63. Dari hasil simulasi diperoleh jumlah biomassa meningkat dua kali lipat dari kondisi awalnya.

Microalgae are unicellular microorganisms that have great potential as future biomass producers, being able to contain high amounts of lipids despite the nitrogen deficiency conditions while consuming industrial CO2. The growth of microalgae an important role in the production of more biomass. The intensity of light is one of the factors that influence its growth so that it can be adjusted incoming light intensity to maximize biomass yield. Then performed optimal control on the light intensity using the Pontryagin Minimum Principle. In this Final Project shows an increase in the number of biomass within 2 with the initial conditions (s,q,x)=(20,10,1.825) with the proportion c=42 and the initial conditions (s,q,x)=(25,15,2.825) with the proportion of c=63. From the simulation results obtained the amount of biomass doubled from the initial conditions.
