Complaints about blast wave vibrations often occur due to blasting activities in a mining operation area. The main cause of this incident is the high level of PPV from the vibration waves resulting from blasting activities. Because of that research to reduce PPV levels as little as possible but still achieve the objectives of blasting activities continues to the present. Calculations for predicting PPV levels to date generally use the Scaled Distance method which does not take into account aspects of delay timing. To pay attention to the aspect of delay timing, the signature hole method is used. This is because the signature hole method in its calculation allows the calculation of wave superposition to a full blast from the wave signature that has been obtained from measurements in the field. However, until now the calculation of the signature hole method in practice is still limited and rigid in the calculation of its variables so that it is not enough to meet practical needs with real conditions on a daily basis. Based on that, this research construct software to be able to answer those needs. The software in this study was made using Microsoft Visual Studio 2019 and MATLAB R2018a using the C # and Matlab programming languages. Inputs for the software made in this study were taken by exporting files from Blastware and Shotplus software as well as creating text files manually, in addition to the input text files for this software also using direct input on the software interface. The output of this software is the recommendation of an optimal blasting design scenario from some of the scenarios provided as well as a visual representation and calculation report.
