The treatment on optical fiber can be in the form of heating, applying connection material, pressure, indentation or by giving treatment by replacing protective sleeves and jackets. For this reason, optical sensors such as waveguides are continuously optimized in every aspect, one of which is their mechanical properties, such as their resistance to pressure. Previously, someone had researched the construction of a waveguide, but had not yet analyzed the stress and strain. The aim of this research is to determine the exact composition of the waveguide with polyester-chitosan composite material. This study uses the finite element principle using packaged software to simulate waveguide conditions. The composition variation for the waveguide itself is 50% Polyester - 50% Chitosan, 40% Polyester - 60% Chitosan, 30% Polyester - 70% Chitosan, 20% Polyester - 80% Chitosan, 60% Polyester - 40% Chitosan, 70% Polyester - 30% Chitosan, 80% Polyester - 20% Chitosan with a total length of 50 mm and a maximum width of 1 mm, and a thickness of 1 mm. The load on the waveguide is stressed 20, 25, 30, 35 and 40 MPa. The boundary condition given is the encastre at both ends of the waveguide. The model shows the highest stress when the model is subjected to a maximum pressure of 35 MPa. The best results were obtained when the composition was 80% polyester - 20% chitosan. For von Mises results from the composition of 80% polyester - 20% chitosan produced 43.01 MPa on polyester material and 54.58 MPa on chitosan material. The strain resulting from the composition of 80% polyester - 20% chitosan is 0.03392 for polyester material and 0.05187 for chitosan material. The highest safety factor of polyester material is when the composition is 80% polyester which is 1.465 and the highest safety factor of chitosan material is when the composition is 20% chitosan which is 1.026.
