Abstract

Before coffee products are marketed, packaging is generally carried out first. Apart from protecting against damage, the packaging also aims to make it easier to carry while traveling. The conventional packaging process is quite time and energy consuming. This results in the packaging process being less efficient. With an automatic packaging system, it is hoped that it will make things easier and save time and energy. Automatic coffee bean packaging tools are built using several electronic devices. Arduino Uno is used as a controller, a load cell sensor to weigh the coffee packaging, a DS18B20 temperature sensor to measure the temperature of the packaging sealer and a proximity sensor to detect plastic packaging. In the actuator section, a servo motor is used to open the coffee bean reservoir valve (hopper tank), a DC motor is used to pull the packaging plastic and a stepper motor is used to press the packaging plastic. The plastic press is equipped with a heating mechanism using nickel wire so that the two layers of plastic can stick together. An LCD module is used to display information on the weight value of the coffee packaging, the temperature value of the sealer and the status of the packaging process. From the test results, it is known that the coffee bean packaging tool is capable of packaging coffee beans automatically. Coffee beans can be packaged in plastic with the weight and length of the packaging according to the design with a success rate of up to 87.5%

Abstract

The widespread use of smartphones in public places has driven the adoption of power banks as a solution for power needs. However, power banks have several drawbacks. To address these needs in public places, charger station systems have been widely implemented, including solar panel-based charger stations as their power source. These developments have also extended to commercial applications, allowing the use of charger station facilities in public places to be subject to specific charges. In this study, a solar charger station system with coin-operated payment for electricity was developed. Additionally, for system security, a feature was added to limit the current flow to the load to a specific amount. The charger station was built using several components, including solar panels, solar charge controllers, and batteries, which are integrated to produce electricity. An inverter is used to convert DC current into AC current, which is then connected to electrical terminals via a solid-state relay switch. Arduino Uno is used to control the electrical connection from the inverter to the terminal through the solid-state relay based on data from the coin acceptor and the PZEM-004T sensor. An LCD is also used to display information required by the users. The test results showed that the solar charger station system could successfully charge smartphones using 1,000-rupiah coins with a 100% success rate. With a rate of 1,000 rupiahs per 40Wh, the charger station system can disconnect the power supply to each load after consuming 40Wh of electricity. Additionally, the system is capable of disconnecting the load when the attached load exceeds 40W.
