The Analysis of Dry Weather Aerial Photography in Sermo Kulonprogo Reservoir using DJI Spark Drone

Abstract

Drones are a very important medium in the world of aerial photography to map military operations, agricultural areas, plantations, mining, urban planning, disaster mitigation, and outreach to remote areas and two types have been identified which are the winged and quadcopter. This research was conducted to map the drought-prone areas during the dry season in the Sermo Reservoir area, Kokap, Kulon Progo Regency between 14-15 August 2019. This involved the use of the DJI Spark quadcopter due to its more stability and wind resistance. The process involved connecting the DJI Spark drone remote controller to a smartphone, opening of DJI Go application, DJI Spark drone activation, smartphone installation on the remote controller holder, propeller installation, GPS settings in a locked position, drone flight and position adjustment, and capturing of the images on the smartphone screen. The results showed the water flow of the Sermo Reservoir has decreased by approximately 4 meters due to the dry season. This was evident in the changes from its original position of136.6 meters above sea level to 132.6 meters and this limits the quantity of water available to irrigate rice fields. The reservoir still has the capability to supply 800 liters per second in Pengasih District but the results of the aerial photographs showed the existence of drought and a decrease in the water discharge.
