Lightning is a serious problem for modern community. Direct lightning stroke can damage or destroy an obect and hurt or even kill a living thing. Indirect lightning stroke can damage elecronic and microcontroller stuff because it has very small or thin insulation. For all of that reason, Lightning Detection System (LDS) is needed to minimize the loss that caused by lightning strike. LDS can split into real time application and historical application. Real time application of LDS used as early warning of lightning strike. Historical application of LDS used as consideration in long planning such as structure planning, work shift planning, and lightning protection planning, etc. Observation area is DKI Jakarta from 4th April 2017 until 18th July 2018. In this study, the data collection is done through documentation studies. Data collection done by collecting data from existing database that belong to PT PLN Puslitbang using software Vaisala FALLS and web interface Thunderstorm Manager. The data that collected is the location, time, and peak current of flash. Lightning data then get processed using Microsoft Excel and Google Earth then shown as flash density map, variance of monthly lightning events, and peak current probability. That lightning data also used to determine the risk of lightning strike to an asset and can be used to evaluate the correlation between lightining event and fault event.
