Abstract
Reaktor merupakan alat yang penting dalam industri kimia.
Reaktor mengubah bahan baku menjadi produk dengan reaksi
kimia. Desain dari sebuah reaktor tergantung pada banyaknya
variabel. CSTR (Continous Stirred Tank Reactor) merupakan
salah satu reaktor yang umum dalam industri. Volume CSTR
tunggal yang besar dibutuhkan ketika konversi yang diinginkan
besar namun reaktor CSTR yang dipasang secara seri mampu
mengatasi masalah tersebut. Perubahan konversi intermediate
akan merubah volume total multiple CSTR yang dipasang secara
seri. Asumsikan bahwa volume reaktor yang kecil akan
menghasilkan total biaya yang kecil, maka penelitian ini akan
menentukan konfigurasi multiple reaktor CSTR dengan volume
minimum dan melakukan analisa kestabilan steady-state pada
masing-masing reaktor pada berbagai konfigurasi multiple reaktor
secara grafis maupun secara analitis. Berdasarkan hasil simulasi,
multiple CSTR dengan konfigurasi seri menghasilkan volume
total reaktor yang paling kecil sedangkan rangkaian parallel
menghasilkan volume terbesar. Hasil analisa kestabilan secaira
grafis menunjukkan jika grafik memiliki satu titik perpotongan
maka titik tersebut stabil dan hasil analisa kestabilan secara
analitis menunjukkan hal yang sama sedangakn jika grafik
memiliki 3 titik perpotongan maka reaktor memiliki 2 titik yang
stabil yaitu upper dan lower sedangkan titik bagian tengah tidak stabil namun hasil analisa secara analitik menunjukkan bahwa
hanya perpotongan pada bagian bawah yang stabil.

Reactor is an important equipment in chemical industry.
Reactor converts raw material to be a product with chemical
reaction. Design of reactor will depend on amount of the variable.
One of the most common reactor in chemical industry is CSTR
(Continous Stirred Tank Reactor). Big volume of single CSTR is
needed when high level of conversion is desired but multiple
CSTR in series is able to deal with that problem. The changing of
intermediate conversion will change the total volume of mutiple
CSTR in series. Assume that small volume of reactor will result
low total cost, so this study will deteremine the configuration of
multiple CSTR with minimum volume and perform an analysis of
stability for each reactor on various kind of multiple reactor
configuration by graphical analysis and analytical analysis. Based
on the simulation, multiple CSTR with series configuration result
smallest total reactor volume while parallel configuration result
highest total reactor volume. Graphical analysis showed that the
graph with one intersection is stable and analytical analysis
showed the same result. If there are three intersection, the reactor
has two stable point that is the lower and upper point but the
middle point is unstable however the analytical analysis showed
that only lower point is stable
