Abstract

Robotic-based sorting systems offer an innovative solution to enhance efficiency and accuracy in the logistics industry. This research aims to design and implement a robotic system capable of automatically sorting goods by integrating barcode scanning technology and line tracer navigation. The system is built using an Arduino Mega 2560 as the main controller and is equipped with Stepper motors, DC motors, mecanum wheels, a GM65 barcode scanner, and various supporting actuators.Experimental results show that the GM65 sensor can optimally read barcodes at distances ranging from 15 to 55 cm. The servo motor demonstrates an accuracy rate of over 98%, while the Stepper motor performs optimally at a minimum voltage of 9.0 V. Additionally, line sensor calibration yields a threshold range between 528 and 573, ensuring accurate line detection. The system also exhibits stable movement with consistent speed and minimal travel time variation, indicating efficient operational performance.By integrating these technologies, the developed robotic sorter system significantly improves productivity, accuracy, and reliability in automated goods sorting processes. The implementation of this system is expected to support automation in the logistics sector and provide a practical solution to distribution management challenges in the era of Industry 4.0.

Abstract

Utilization of electronic technology in various aspects of human life, both in household needs, education, industry, and human habitation itself. In this discussion is how to design a queuing system based on the Internet of Things using a Raspberry Pi W Zero controller. Internet of Things is a concept in which an object or object is implanted with technologies such as sensors and software with the aim of communicating, controlling, connecting, and exchanging data through other devices while still connected to the internet. In designing this queuing system, a website is needed to support this tool to make it easier for users to register online without having to manually take queue numbers. The programming language used for the Raspberry Pi W Zero controller uses python. Testing this queuing system 100% went well and according to what was designed for the design of an Internet of Things based anti covid 19 queuing system using the Raspberry Pi W Zero. With this tool, it can make it easier for users to register queue numbers and be able to run the appropriate Health protocol system.

Abstract

Most people, especially women, are generally not educated about what ingredients are contained in a cosmetic and only rely on social media as a reference by looking at influencers who advertise a beauty product. To consult with a dermatologist also requires a lot of money, so they choose not to care about it, this causes many cases handled by dermatologists are cases that are too severe. Therefore, there is a need for awareness and education for women, especially teenagers regarding the use of illegal cosmetics, so through this research, the authors try to propose a free, expert-based platform that can be accessed in general by people from anywhere and anytime to carry out self- assessments or self-examinations. or education that makes it easier for the public to get easy and detailed information access regarding the hazardous ingredients contained in cosmetics. So in this study, we propose an educational media and expert-based assessment of the symptoms of the disease suffered in the form of developing an expert system based on the forward chaining algorithm and certainty factor, which involves a dermatologist. based on the results of testing the accuracy of 20 data samples, 18 data were appropriate and 2 data were not appropriate so that the accuracy obtained was 90%, and from user satisfaction testing it was found that 80% were satisfied with the system created and 20% were not satisfied.

Abstract

Sign language is a form of language that can be learned which prioritizes communication with body language, facial expressions, and some non-sounds. This sign language is widely used by the deaf and mute. However, there is still a lack of institutions teaching sign language, books on sign language, and a tool for learning sign language. This study aims to design a hardware system that can translate sign language and output in the form of audio and display on the LCD. The stages of the research included designing the physical form of the device, testing the sensor flex, testing the MPU6050, testing the Nrf24l01, testing the Dfplayer, testing the Liquid Crystal Display (LCD), and testing the overall device on the A-Z alphabet. The results showed that when the Flex sensor was not indented the average error was 1.23%, and when it was indented the average error was 2.01%. The delay time required in sending data using Nrf24l01 media for conditions without obstructions is 0 seconds with a distance of 1 meter, with a barrier of 9.84 seconds with a distance of 3 meters, at a distance of 3 meters the data cannot be sent.

Abstract

Electrical energy is a primary need in modern life that continues to increase along with the rapid development of technology and the use of portable electronic devices. Dependence on conventional power plants sourced from fossil fuels is considered unable to meet energy needs when outside the conventional electricity grid. Therefore, a more flexible and easy-to-produce renewable energy alternative is needed. One solution that can be offered is the use of piezoelectrics, which are capable of producing electrical energy only through mechanical pressure without relying on weather conditions such as solar power plants or wind power plants. This study aims to design and test a portable power generator based on piezoelectrics. The piezoelectric circuit is designed with a series-parallel configuration of 30 piezoelectric pieces, which are connected to rectifier diodes, elcos, storage batteries, and step- down modules for voltage adjustment to electronic devices. The test results show that the device can produce an output voltage of up to 32.47 VAC. Then, the highest DC voltage is 87.3 VDC. The voltage stored in Elco is 24.92 VDC, with the final output on the battery being 13.69 VDC and a current of 1 A within 2 minutes. Meanwhile, the time required to charge 1% on a mobile phone is 9 minutes, indicating the potential effectiveness of the device with further pressure increases.
