Advanced in the field of fracture mechanics have helped to offset some of the potential dangers posed by increase technologycomplexity. Our understanding of how materials fail and our ability to prevent such failures has increased considerably since World War II. Much remains to be learned, however, and existting knowledge of fracture mechanics is not always applied when appropriate. In the first instance, existing procedures are sufficient to avoid failure, but are not followed by one ore more of the parties involved, due to human error, ignorance, or willfull misconduct. Poor workmanship, inappropriate, or substandard materials, error in stress analysis, and operator error are examples of where the appropriate technology and experience are available, but not applied.

Distribution system is very important in the distribution of electric power to the load. Therefore, a good and efficient distribution system is needed. The underlying cause of poor electric power distribution system is the amount of voltage drop values in the existing system. In the electric power distribution, 20 kV medium-voltage and 380/220V low voltage networks are used. The distribution system of Gandum Feeder in Angke Substation uses medium-voltage network with Underground Cable channel. They are used because of the towering buildings and the dense population in the area. It is known that the longest the channel and the load current are, the greater the voltage drop. From the result of the voltage drop calculation of Feeder Gandum in Angke Substation, which uses manual calculation and ETAP 12.6.0 program, it showed a slight difference in the result. The result of the voltage drop obtained from manual calculation showed that the percentage value of voltage is 1,94%, while the result obtained from ETAP 12.6.0 program showed that the percentage value is 2,01% These results are still in the PLN standard, because it has not exceeded the specified standard that is -10% of its nominal voltage.
