Abstract

Flat coil sensor works by evaluating changes the mutual inductance of the measuring object immersed in a magnetic field of coil. The spiral coil detects without a physical contact with object made on FR4 Printed Circuit Board (PCB). LC-oscillators are used to evaluate change the inductances of two identical sensors in a differential structure with a measured object of copper beryllium (CuBe) moving parallel between the sensors. Flat coil evaluation sensor using LC oscillator produces the eigen frequency of 1MHz up to 2MHz. The linearization of flat coils are carry out using output differential between two oscillator and shown a linear output.

Abstract

This research aims to design and develop a Mocaf (Modified Cassava Flour) processing system based on automation using Omron PLC software. Mocaf flour is a cassava-derived product whose processing involves fermentation, drying, and milling stages. The designed system focuses on improving production efficiency, maintaining product quality, and minimizing errors caused by human factors. The research method includes system requirements analysis, hardware and software design, as well as implementation and testing on a prototype. The Omron PLC serves as the main controller, integrating various sensors and actuators to monitor and control the processes automatically. The system is also equipped with a user interface to facilitate process monitoring and parameter settings. The results indicate that the designed system can optimize the Mocaf flour production process with high precision and reliability. Additionally, the use of Omron PLC-based automation has proven effective in reducing processing time and increasing productivity. This research is expected to contribute to the development of a more modern and efficient local food industry.

Abstract

The self-balancing robot is unstable and will fall without external control so an excellent control method is needed so that the robot can automatically maintain a balanced position. This research aims to design and control a two-wheeled self-balancing robot to be able to maintain a good balance perpendicular to a flat surface. In this study, tests were conducted by comparing the P, PD, PI, and PID control methods to obtain the best control method to be applied to the two-wheeled self-balancing robot. The PID controller proved to be the best compared to other control methods. The performance of the PID controller carried out in the study is measured by the length of time the robot can stand stable at rest, in motion, and the presence of external disturbances. The system uses an Inertial Measurement Unit (IMU) sensor to reduce the centrifugal force exerted on the robot, detects the tilt angle and angular velocity, and uses an Arduino as the control center and data process. The self-balancing robot that has been designed can balance itself stably on the PID parameters used, namely , and . With these PID parameters, the robot can maintain an upright and balanced position with or without external disturbances and can stabilize for 600 seconds (10 minutes) even longer as long as battery power is still available.

Abstract

Orchids are one type of plant that can be cultivated in a greenhouse. The growth of orchid plants is influenced by several factors, including altitude, light intensity, envirnmental temperature, environmental humidity, and water content in the planting medium. If some of these factors do not meet the needs, then the growth of the orchid plant will be disrupted, the roots and flowers produced by the orchid will not be healthy and beautiful. The aim of this research is to create a system that is able to monitor and control the environmental conditions in the place/location where this orchid grows so that it is always in a stable condition. The technology used is misting misting based on an Android application using sensors and IoT to maintain and maintain the condition of orchid plants so that they are always in optimal condition. In the results of the tests carried out, the data obtained were good, namely that this instrument had an accuracy of 80%. The application that has been created is capable of controlling and monitoring the environmental conditions of orchids very well

Abstract

Budidaya anggrek memerlukan suhu dan kelembapan yang terjaga dalam batas optimal agar pertumbuhan tanaman berlangsung baik. Penelitian ini bertujuan untuk mengembangkan dan menguji sistem pemantauan serta pengendalian suhu dan kelembapan berbasis Internet of Things (IoT) dengan teknologi pengabutan pada rumah kaca anggrek. Metode yang digunakan meliputi integrasi sensor SHT20 dan GY49, mikrokontroler ESP32, serta aktuator seperti Sonoff, pompa, dan nozzle, dengan sistem pemantauan berbasis platform ITERAHERO. Kalibrasi dan validasi dilakukan untuk menjamin akurasi sensor. Hasil pengujian menunjukkan bahwa sistem mampu menjaga suhu dan kelembapan dalam rentang ideal (26–28°C dan 70–90%), dengan akurasi sensor di atas 98% dan waktu respons aktuator kurang dari satu detik. Sistem ini terbukti efektif dalam mengatur mikroklimat rumah kaca secara otomatis dan real-time, sehingga mendukung efisiensi energi dan produktivitas budidaya anggrek
