“…In addition to being able to find the center of the fire, the drone is also designed to be able to extinguish fires in a method that can minimize smoke from burning. For this reason, the authors innovate to use Fire Extinguisher Balls, which are balls like fire extinguishers filled with fire suppression fluid but in the form of a ball with a foam sheath wrapped in PVC [21] [22][23] [24]. These Fire Extinguisher Balls react quickly to heat and fire so that when the drone drops the ball to a hotspot it will trigger a substance embedded in the ball and respond by spreading the dry chemical fire suppressant inside [25][26] [27].…”

Burning activities are still common in Indonesia, but the handling by the government has not been able to maximize performance in extinguishing fires that are difficult to achieve with standard equipment. The drone that the author developed is named Zerologic which is designed to use a remote monitoring system with machine learning algorithms and image processing methods in finding hotspots using a webcam camera. This camera sends object data which is then processed on the Raspberry Pi 4 using the OpenCV Python software. Besides being designed to search for hotspots, this drone can also minimize the spread of smoke by using a fire extinguisher ball that functions as a fire extinguisher that will be carried directly by the drone. ZEROlogic drones are useful for making it easier for forest firefighters to handle forest fires by finding and extinguishing hotspots that are difficult to reach by humans. In addition to being able to search for and search for fire, this drone ZEROlogic goes directly to the hotspots. Keywords: Drone; Fire Extingusher Ball; Image Processing; Machine Learning

“…The dip coating method is a thin film coating technique by dipping the substrate into a container containing a solution. The substrate is immersed at the specified time then immersed and pulled vertically [15]. The benefit of this method are low cost, have a high level of precision and do not damage the environment [16].…”

The availability of fossil energy is decreasing day by day. Therefore, a New Renewable Energy solution is needed. One of the renewable energy is DSSC. DSSC is a photoelectrochemical-based solar cell that has a lower cost, less difficult preparation, and is environmentally friendly. DSSC be composed of working electrode, dye, electrolyte, and counter electrode. This researchintend to investigate the performance of the working electrode where the manufacture of a thin film using the dip coating method with variations in immersion and its effect on the efficiency of DSSC. This research is an experimental research. In this study, the semiconductor working electrode was made based on 9% ZnO/Ag synthesis by going through a sol-gel process. The working electrode was coated with variations of immersion 1, 3 and 5 times. The 9% ZnO/Ag thin layer was characterized by UV-DR Spectrometer. Based on the results, 9% Ag doped ZnO deposited on the ITO substrate with variations of immersion 1, 3 and 5 times showed, a band gap of 3.09 eV, 3.10 eV and 3.12 eV, respectively. Based on these data, it was applied to DSSC with the optimum efficiency shown at the electrode 1 time dip. Therefore, the greater the amount of immersion, the lower the efficiency of the DSSC.The availability of fossil energy is decreasing day by day. Therefore, a New Renewable Energy solution is needed.

“…Mientras que trabajos recientes como el reportado por(Yohandri, Khairunnisa, Ramli, & Zainul, 2019), presentan el desarrollo de la tecnología de recubrimiento por inmersión basada en microcontroladores de libre código como Arduino. El sistema electrónico se implementa para controlar el tiempo de inmersión y la velocidad de extracción a través de un motor paso a paso, datos que, además, son ingresados digitalmente a través de un teclado con un rango de valores de 0.02 mm/s a 10 mm/s.…”
