Abstract

Eccentricity measurement techniques are developed to ensure optimization of operational works, either for large or small objects such as upper bearing kWH meter. Small object eccentricity testing has been done by using precise and sensitive touch trigger probing and a special sofware that makes it expensive. This study developed a more economical vision systemin eccentricity testing. It consists of bearing holder and CCD microscope as an image recorder and computerized image processing. It uses three tested bearing during image recording process, which obtained 12 images from each tested bearing taken from every 30o angle, and one image as registration reference. Image registration process is conducted to correct imperfections bearing mounting into its holder and use centroid method to test the eccentricity of upper bearing kWH meter. This study is succeed in making an eccentricity testing prototype of upper bearing kWH meter which obtained result of 2nd bearing has its largest standard deviation. From all standard deviation value obtained that x -axis (horizontal) standard deviation is larger than y-axis (vertical) which means that detection of x direction is more accurate than y direction. To enhance precision image acquisition in the next study, it is expected the use of a computer system with homogeneous illumination is enabled.

Abstract

The use of Borax as a food additive has adverse effects on public health. In an effort to prevent contaminated foodstuffs from becoming public consumption and to detect this contamination quickly and effectively, this research proposes the design of an Internet of Things (IoT)-based borax detection tool using color recognition technology from the HuskyLens Camera. This tool is designed to detect the presence of borax in food with high accuracy and in a short time. This research uses the HuskyLens Camera as a sensor that is sensitive to the target contaminant, and the data obtained from this sensor is transmitted through the IoT network to the MIT App Inventor platform. Optimized detection methods and data processing algorithms are used to accurately interpret the sensor results, providing authorities with immediate information on the safety status of the tested foodstuffs. Experimental test results show that the proposed detection tool has good performance in detecting borax in various types of foodstuffs. It provides an efficient and reliable solution to the challenge of food contamination. With the integration of IoT technology, the detector is able to provide real-time information to authorities, potentially raising awareness about overall food safety. Thus, the design of this IoT-based borax detector has great potential to overcome the problem of food contamination and make a significant contribution to maintaining public health.

Abstract

Processing rice products into rice requires further processing, where the grain harvested from farmers is processed into rice. The Nagari Binaan Community Service team from Padang State University will later develop this process. Farmer groups say that the availability of continuous and cheap electricity is their obstacle in producing good and cheap rice products. Counseling and assistance in making civil buildings capture turbulence water micro-hydro power plants is a solution to partner problems offered by the community service team of the Nagari program assisted by Padang State University. The output of the Nagari Fostered Program will be used to build a 5000-watt capacity power plant, supporting the need for free and environmentally friendly electricity. This aligns with the government's renewable energy program for 2030, which aims to produce 25% of the national electricity from renewable sources. This program is planned for 3 (three) stages, where the first year is mapping and detailed engineering design in the form of reports and design drawings. The second year is in the form of civil construction, and the third year's target is the installation of electrical machines and panels for commissioning. There will be training for partners, such as farmers in Kanagarian Kamang Hilia, Agam.

Abstract

The dosimat feeder is a device used to weigh additional materials before entering the mill for grinding. It includes a hopper that functions as temporary storage before the material is transferred to the belt conveyor. The main issues addressed in this study are frequent material shortages that can disrupt industrial operations, and uneven filling that may affect system performance and reduce production efficiency. This research adopts the Research and Development (R&D) method, aiming to develop a product and evaluate its effectiveness. The system is designed using an Arduino Uno microcontroller to process data from sensors. Ultrasonic sensor 1 is configured to control material filling, while ultrasonic sensors 2, 3, and 4 are used to monitor material evenness, with a maximum distance tolerance of 2 cm for ultrasonic sensor 1. A DC vibrator motor is activated when the material inside the hopper is detected to be uneven. The results of the study show that the material level and surface flatness status are successfully displayed on a 16x2 LCD.

Abstract

The Dosimat feeder is a device used to accurately weigh additional materials before they enter the mill for the grinding process. The Dosimat feeder adjusts the material weight by increasing the motor speed when the hopper does not release supplementary materials such as gypsum. This research employs the Research and Development (R&D) method, which aims to produce a specific product and test its effectiveness. The results show that the measured weight data is displayed on a 16x2 LCD via an I2C module. A buzzer activates when the material weight drops below 331 grams, and the motor stops until the minimum weight is reached. Testing indicates that the load cell has an average accuracy of 98% (with an error margin of 0.6%–5%) for weights ranging from 100 to 400 grams. Motor speed decreases from 32 rpm (at 360 grams) to 21 rpm (at 480 grams) as the load increases. The system operates optimally when Dosimat 2 and 3 are active and all three LEDs are on, thereby improving production efficiency and preventing losses due to material shortages.

Abstract

Uneven material distribution on the dosimat feeder belt conveyor at PT Semen Padang causes the belt to tilt, resulting in material spillage and decreased production efficiency. To address this issue, an Internet of Things (IoT)-based control system was designed to detect belt tilting and automatically guide the material back to the center of the belt. This system utilizes an ESP32 microcontroller, a load cell sensor to read load distribution, four limit switches (two for detecting tilting and two for detecting material that veers off the track), two servo motors to direct material from the right and left sides, and a buzzer to provide an alert when material goes off the track. Real-time monitoring is conducted through the Blynk platform. Testing results showed that the load cell sensor had an average error of 1.68%, with the highest error of 3.3% at a 100-gram load and the lowest error of 1.17% at 200 and 400 grams. The limit switches for tilt detection were activated at an 85-gram load to trigger the servo, while the limit switches for material off-track were activated at a 100-gram load to stop the system and activate the buzzer. This system has proven effective in reducing material loss and improving production efficiency.
