Abstract

Shrimp crackers are snacks made from tapioca flour and shrimp. Crackers also have variations of colour, shape, size, smell, taste, crispness, thickness, or nutritional value. Some of the production of ready-to-eat shrimp crackers is made by home industry that still use traditional equipment to reduce the oil content in the cracker. This affects the quality of the crackers which can cause the crackers not durable and smell it is caused by high oil level due to not optimal draining. Therefore this study aims to design a prototype of oil spinner machine for shrimp crackers equipped with an electric motor, a 4x4 keypad as a timer setting, a current sensor and a voltage sensor to calculate the cost of using electric power, the HC-SR04 sensor as a sensor that detects the liquid level in the container, LCD as a monitor, and a buzzer that functions as an alarm when the engine is off and when the oil container is full which will be connected to the arduino uno microcontroller. After testing with different times, the slicing process was succedeed in reducing the oil content in shrimp crackers by 21.55 % and the cost of using electric power on machine was Rp. 0.8444,- per minute and its also equipped with an oil reservoir that can hold an oil level as high as 3 cm so that the machine is more ergonomic that can improve the quality of shrimp cracker production.

Abstract

Ergonomic challenges are associated with study tables often ignore the user's optimal dimensions and posture. A comfortable study environment is needed to improve productivity and health. It is necessary to design and implement an automatic control system for the table height and study light intensity, utilizing ultrasonic sensors and Light Dependent Resistors (LDR) to adapt to the user's needs. Previous studies often neglect the integration of adjustable furniture with smart lighting systems, causing discomfort and inefficiency in the study environment. A new method is needed by combining a linear DC motor actuator with an L298N motor driver to facilitate table height adjustment between 70 cm and 80 cm, while using a relay module to control the brightness of the lights based on ambient light conditions. The results show that the developed system significantly improves user comfort and health, demonstrating its effectiveness in various settings, including home and workplace. The results show that ergonomic design when paired with automation, can improve user concentration and productivity. This study contributes to the field of ergonomic design by providing a practical solution that addresses table height and lighting, ultimately promoting a healthier and more efficient study environment.

Abstract

This study aims to develop a simulation of the ETCS (European Train Control System) system based on Arduino Uno for Light Rail Transit (LRT) trains in South Sumatra. The main focus of the study is on the automation of train operation, the identification of disturbing objects, and handling potential errors in programming. Tests and analysis show that an active Ultrasonic Sensor allows the train to stop if there is an object blocking it in front of it at a distance of less than 20 cm. The TCS200 color sensor plays an important role in activating the Servo so that the crossbar can be active so that the train can run again. The colored signal LED lights become markers, the red LED indicates the down bar and the green LED lights indicates the up bar. The LCD is here to display the destination of the train station which is located on the side of the train body. The buzzer is a marker for the train stopping and the timer is set to 5 seconds per each train stopping at the station. Of course there are drawbacks, namely that there are no automatic doors when the train stops at the station and the station is relatively quiet and there are no additional accessories and lights at the station

Abstract

Catfish farming in Indonesia has significant potential; however, conventional methods of counting fish fry still face various challenges, such as the considerable time required and a high risk of errors. This study aims to design and build an automatic counting device for catfish fry based on the Arduino Mega 2560 microcontroller, integrated with an E18-D80NK infrared proximity sensor and a DS18B20 temperature sensor. The device is specifically designed to count catfish fry measuring between 6 to 8 cm, where the infrared proximity sensor is used to count the number of fish fry passing through, while the DS18B20 sensor functions to detect the water temperature in the holding tank. The operational process of the device includes inputting the number of fry via a 4x4 keypad, opening the counting path using a servo motor, measuring the water temperature, displaying data on a 16x2 LCD, and closing the path after the counting process is completed. The test results indicate that the DS18B20 sensor has an accuracy of 97.68% with an average error of 2.32%, while the infrared proximity sensor achieves an accuracy of 89.08% with an average error of 10.92%. This device successfully counts the number of catfish fry automatically, monitors the water temperature, and displays information in real-time on the LCD. Therefore, the catfish fry counting device based on the Arduino Mega 2560 is expected to enhance time and labor efficiency, as well as minimize errors in the counting and distribution processes of catfish fry.

Abstract

Air pollution caused by fossil fuel-powered vehicles has a significant impact on public health and the environment, encouraging the transition to electric vehicles in accordance with Presidential Regulation No. 55 of 2019. Electric vehicles use batteries as their main energy source, making a safe charging system essential to prevent overcharging. This study designs a lead-acid battery fast charging system based on the Constant Current (CC) method with a constant current of 2.7 A, equipped with an automatic cut-off. Testing was conducted through field observation, interviews, and literature review. Results show that the charging time is only ±3 hours 13 minutes, significantly faster than the conventional method (10 hours), with component measurements within tolerance limits. The PZEM-017 and voltage divider sensors accurately read voltage according to the datasheet. This system proves to be efficient, safe, and capable of preventing battery damage due to overcharging.

Abstract

Group travel in densely populated areas presents risks of losing members, especially during peak periods such as weekends. This study aims to develop a wireless communication glove device as an aid for inter-member detection to prevent loss during travel. The method involves designing a device based on the Wemos microcontroller integrated with GPS sensors for position tracking, MAX30100 heartbeat sensor for health monitoring, an OLED I2C display as visual interface, and a buzzer as alarm. The system functions by identifying unique IDs between devices within a certain radius and triggers an alarm when connection is lost. Testing results indicate the heartbeat sensor accuracy with an average deviation of less than 3 bpm compared to manual measurements. Maximum connection distance without physical obstacles ranges from 24 to 26 meters, decreasing to 18 meters with wall obstructions. The master device detects connection loss within approximately 20 seconds, indicated by an audio alarm and display changes on the OLED screen. The estimated operational duration is 5.5 hours at 2.4 Watts power consumption. Overall, this device effectively prevents member loss with simple health monitoring and reliable connection detection features.
