Deteksi Kerusakan Pipa Dalam Bentuk Retak Dan Penyok Menggunakan Sinyal Suara Dan Dual Mikrofon

---

Piping system is used for fluid distribution that is very important in various fields of industry. When compared to other transportation systems such as vehicles, piping systems have a higher level of integration and are more effective. The need for systems is increasing in the industrial sector. Therefore, various types of damage that can occur in the pipeline system are important to be assessed and prevented. To prevent various losses and work accidents it is very important to detect damage to the pipe system. Pipe damage in the form of crack and dented is a problem that often occurs in pipe systems. Crack in the pipe can cause leakage and the level of damage will increase due to fluid pressure in the pipe. Dent in the pipe can cause blunt impact on the pipe and will cause a blockage that can divert the flow of fluid in the pipe. In this study, the detection of damage to the pipe is done using sound signals and dual microphones. The sound signal method is an intelligent structural health monitoring that can prevent damage at a lower cost. Sound excitation was generated by loudspeaker and the response of the sound signal is sampled using a dual microphone. The damage provided consists of repetition and dents in different sizes, distances and polar positions. Sound signal data from dual microphones is processed using wavelet transforms. From the experimental results it was found that the greatest wavelet coefficient of the microphone position is estimated to be the polar position of the damage with the largest estimated error in the combined damage at the quarter dent position of 6.81%.
