Abstract

This research is about post-harvest tomato selection where the TCS230 color sensor Will go through a way of assessing light intensity by emitting caused by super bright leds through objects, reading light intensity values ​​starting with an 8x8 photodiode matrix, on 64 photodiodes will be divided into 4 parts of color reading, on the color illuminated by the led reflected by the led light to the photodiode, the reflection of the light will be extended by a wave that changes depending on the color of the object being detected, the TCS230 color sensor can read several colors. A tomato will enter its place, the tomato may always stop right under the sensor so that the sensor will not be able to detect the presence of tomatoes that pass, and cannot read the RGB value of the tomatoes that pass. The results of 10 tests showed that selecting tomatoes successfully classified tomato grades, could control servo motors and DC motors automatically based on RGB values ​​through a processing time of about 3 seconds with an error rate of 2%.

Abstract

In the digital era, the need for electricity supply is very large. According to research data from the Ministry of Communication and Information, in 2019 Indonesia had a high need for electrical energy, reaching 50,000 Mega Watts. Fulfillment of renewable energy such as PLTO in Indonesia's maritime areas is still very possible. The aim of this research is to design a PLTO device using the cylinder float method on a small scale. Ocean waves will move the buoy up and down and move a series of gears and generators. The amount of lifting power (buoyancy) is influenced by the dimensions (length and width) of the cylinder float. The dimensions (length and location of inertia) of the arm also determine the amount of torque to rotate the gearbox and generator. From the results of the float mass-based PLTO design, it can be seen that on the first day of data collection the highest voltage was 16.06 V, current 0.66 A and electrical power 10.59 W, on the second day the highest voltage was 18.2 V, current 0.66 A and power electricity 10.53 W.
