Abstract

Tomato fruit yields have a variety, not only ripe fruit but also the condition of tomatoes that are still raw or half-ripe. By naked eye, tomato ripeness can be seen by the difference in three colors, namely red, yellow and green. Each color difference describes the level of maturity. However, human decisions in distinguishing the color of ripe tomatoes can vary and are more subjective. With the help of an image processing system, the selection of tomato ripeness can be faster and more objective. This study uses the YOLOv4 algorithm which is implemented into a mobile computing device, namely the Raspberry Pi 3, to select the tomato image captured by a camera. The results of the YOLOv4 image process will be output to the actuator in the form of a conveyor equipped with a wiper that will sort tomatoes automatically. The result of this research is a prototype with the YOLOv4 algorithm that has been trained with the tomato dataset.

Abstract

Photovoltaic functions to convert solar energy into electrical energy. The use of photovoltaic requires a charging controller to improve the performance of PV to be more optimal. The parts of the charging controller consist of a DC-DC converter and maximum power point tracking (MPPT). DC DC converter is used to change the value of the output voltage of the photovoltaic to reach the peak power of the photovoltaic. To determine the peak power value of photovoltaic, MPPT is needed with incremental conductance algorithm. The DC-DC converter uses a buck converter type with a switching frequency of 150kHz and an inductor of 35µH. The incremental conductance algorithm embedded in the microcontroller works by comparing changes in current and voltage to get the peak power value. The result of this microcontroller is a pulse wave whose duty cycle varies based on the results of the algorithm. This pulse wave will control the buck converter. From the results of this study the charging controller is able to work by changing the value of the duty cycle according to the PV conditions when absorbing power.
