Palm is an edible feedstock which is immensely popular in Malaysia as an alternative fuel which can substitute diesel fuel. However, use of Palm biodiesel in diesel engine have a negative effect on food security, thus, in this study authors used Mustard biodiesel, which has poor fuel properties, with Palm biodiesel to produce an optimum blend. This blend will have better fuel properties compared to Mustard biodiesel and will help eliminate dependency of Palm biodiesel. To ensure that optimized blend achieves better fuel properties MATLAB optimization tool was used to find out the optimum blend ratio. Linear relationship among the fuel properties was considered for MATLAB coding. The resultant optimum blend is represented by PM. Optimum blend revealed improved fuel properties compared to mustard biodiesel.

Fossil fuel is depleting due to increase in usage and we are facing energy crises. For us to get out of such plight situations, scientists are looking into alternative ways to produce energy that can be attained at low cost and also eco-friendly. Biodiesel can be an effective solution in spite of some limitations to use as fuel because of poor fuel properties. From this point of view, experiment had been conducted to improve fuel properties of palm biodiesel by blending with coconut and jatropha biodiesel. MATLAB optimization tool was used to find out the optimum blend ratio to achieve overall better fuel properties. Linear relationship among the fuel properties was considered for MATLAB coding. The resultant optimum blend ratio and the equations of the MATLAB code were used to predict the fuel properties values and the experimental fuel properties values of the optimum blends were compared with the predicted values.
