Abstract

The quality of the meat can be seen from the level of freshness of the meat. The level of freshness of the meat will determine the meat that is suitable for consumption and the meat that is no longer suitable for consumption. There is a lot of public interest in consuming fish and beef, so there are unscrupulous meat sellers who commit fraud by continuing to market meat that is not fresh and even given preservatives so as not to get a loss. Therefore, a system was designed that can detect the level of freshness and formalin in fish and beef. This tool is designed using Arduino Uno, HCHO sensor, MQ 135 sensor, pH sensor,Sensor Ultrasonic, LCD, Buzzer,Water Pump and DC fan. This tool will detect the formalin contained in the meat by using the HCHO sensor if > 1 ppm. Then the ammonia value and pH value were processed using the Fuzzy Logic Tsukamoto method so as to get the level of freshness of the meat

Abstract

Interactive technology is part of technological developments that can attract the attention of various groups ranging from children, teenagers and the elderly. This interactive technology has developed evenly in various aspects, one of which is financial education. Financial education is an important aspect in the development of children so they can manage finances wisely from an early age. In this era, piggy banks are still used to teach children how to save money properly and correctly. However, children are slowly starting to get bored and their intention to save is decreasing, this is because the piggy bank still has a monotonous storage method and lacks appeal, so children are starting to lose interest in saving their money. One of the media that can increase children's interest in saving is an interactive piggy bank, this media is equipped with ESP32, button, LED, DFplayer, speaker, infrared sensor, color sensor, proximity sensor, stepper motor, relay, solenoid, 16x2 LCD and telegram so that The technology and media developed, interactive piggy banks not only calculate the total number of coins and banknotes, but can also interact directly with children and increase children's understanding of saving money in a good and correct way. By using this method, children will be interested in using interactive piggy banks. Slowly, children's interest in saving will begin to increase and they will start to get used to saving money again.
