Indonesia’s energy consumption is using 95% fossil fuels and considered as a country with a fairly high level of energy consumption. Currently, Indonesia is in the state of energy crisis with oil reserves of 3.7 billion barrels, or 0.3% of world reserves. Leakages in oil piping system are among one of the major problem responsible to the lack of energy resources in some areas. This research aims to apply leakage detection system on pipeline based on acoustic and vibration methods.
Yogyakarta as a city of education becomes one of the destination for young people who want to pursue a university level degree. Their arrival increased the number of Yogyakarta’s population. In Indonesia, the increment of population is followed by the increment of vehicles. Meanwhile, the result of having a lot of amount of vehicles is not followed by the streets capacities and therefore causes traffic jam. Traffic jam creates a high noise level which is produced from vehicle engine, horn and muffler. This noisiness might distract some learning activities and create inconvenient education environment.
