Abstract

The aim of this research is to determine analysis for optimizing tape fermentation using a Temperature and Fermentation Controlled Chamber (TFCC) with a Hybrid System. The resulting numerical model was analyzed using a non-linear differential method using Runge-Kutta. The thing that was analyzed was the change in the rate of yeast concentration, the rate of change in the concentration of ethanol and glucose resulting from the fermentation process. TFCC with Hybrid System Technology is equipped with an automated system accompanied by sensors that detect food quality and can be directly observed through the LCD screen integrated in the device. The research method used is experimental research by designing a tool that can be used to produce/cook fermented foods while monitoring pH, alcohol, glucose levels and temperature levels which are integrated in a set of tools called the TFCC with Hybrid Systems Technology . From the numerical explanation, it can be seen that when t is small, the rate of yeast development in the fermentation process will be small, the number of yeast cells is still small. As a result, the growth rate will be slow. This can be seen from the graph of the increase in X(t) and P(t) as well as the graph of S(t) which is still slow. The greater the time t, the rate of yeast consumption is also greater because the number of yeast cells is also increasing. As a result, the growth rate of ethanol and sugar is also large. This can be seen from the graph of an increase in X(t) and P(t) as well as a graph of a faster decline in S(t). When the maximum consumption rate is reached, then the values of X(t), S(t) and P(t) are constant. The amount of concentration in the resulting ethanol is close to the initial concentration of sugar produced.

Abstract

This study aims to develop a transporter robot as a learning tool for elementary and secondary school students to introduce them to robotics. The robot features a differential drive system and a lifting arm akin to a forklift system. The robot is controlled using an ESP32 microcontroller and connected to an Android application through a Firebase cloud database. Utilizing an IoT platform, the training can be conducted online, allowing students to control the robot remotely while it remains at the training location. The transporter robot is designed to provide an interactive and hands-on learning experience in robotics, enabling students to grasp fundamental concepts in robotics, programming, and control systems. The differential drive system offers excellent maneuverability, while the lifting arm allows the robot to perform tasks such as lifting and moving objects, adding functional aspects to the learning process. Test results indicate that the robot performs well under online control, with fast and accurate responses to commands from the Android application. The use of Firebase ensures stable and real-time communication between the robot and the application. This implementation not only enhances the accessibility of robotics training but also enables the development of students' STEM skills in a more flexible and affordable manner. The study concludes that an ESP32-based transporter robot with online control via an Android application and Firebase cloud database can be an effective and innovative learning tool. This tool aims to enhance students’ STEM skills -especially in programming, control systems, and mechanical design- through interactive, real-world applications.

Abstract

The application of technology in the livestock sector has been carried out to increase the productivity of the livestock business. Closed chicken coops are one of the applications of technology in the livestock sector by utilizing a microcontroller that can control the temperature and ammonia levels in the coop under optimal conditions for fattening chickens. When the temperature rises (hot), the system set on the microcontroller will make the fan turn on automatically. This study aims to improve the offline and semi-manual fan control system in closed chicken coops to become automatic. By utilizing Internet of Things (IoT)-based technology, monitoring the condition of the chicken coop can be more easily accessed remotely. The method uses the if-then rule to regulate fan performance based on variable temperature and ammonia levels. The fan work set-point value can be set through the Android application online. Based on the test results, the IoT system treatment can work well. A consumer satisfaction survey was conducted on breeders with satisfactory results to ensure their feasibility as a commercial product.

Produk ini dirancang sebagai perangkat modular berbasis mikrokontroler dan sensor, yang mudah digunakan untuk pelatihan tingkat dasar hingga menengah. Meskipun pengembangan alat ini telah berjalan melalui riset sebelumnya, pemanfaatan dan hilirisasi produk tersebut masih terbatas karena belum adanya modul pelatihan standar serta strategi promosi yang terstruktur. Hal ini berdampak pada rendahnya tingkat adopsi produk oleh sekolah-sekolah mitra atau komunitas pendidikan lainnya. Permasalahan yang dialami oleh mitra antara lain; belum ada pengembangan modul pelatihan yang efektif dan sesuai dengan kebutuhan pembelajaran STEM untuk penggunaan Smart Robotic Kit di lingkungan TEFA ECC di desa Badean, belum konfermasi dalam meningkatkan keterampilan dan pemahaman pelajar dalam bidang robotika dan teknologi melalui kegiatan pelatihan berbasis Smart Robot Kit dan belum adanya strategi promosi dan komersialisasi produk Smart Robotic Kit agar dapat diterima secara luas oleh sekolah-sekolah di desa Badean.

Abstract

This research presents the development of a teleoperation system for a mecanum wheel robot actuation integrated with the MQTT (Message Queuing Telemetry Transport) protocol to be used as an interactive STEM (Science, Technology, Engineering, and Mathematics) learning tool. The system employs four independently actuated mecanum wheels enabling omnidirectional mobility through coordinated wheel control. The teleoperation architecture utilizes a Raspberry Pi 3B+ connected to HiveMQ Cloud broker implementing MQTT protocol for real-time remote actuation via Flutter-based mobile interface. Each wheel actuation is controlled through L298N motor drivers operating at 300Hz PWM (Pulse Width Modulation) frequency, providing precise speed and directional control. Experimental results demonstrate system reliability with an average position deviation of 1.86 cm for forward actuation, 1.93 cm for backward, 2.64 cm for left slide, and 1.71 cm for right slide movements across 140 cm distance. The MQTT integration achieves a command execution latency of 200-400ms, suitable for educational teleoperation applications. The Flutter interface provides intuitive control with real-time visualization of wheel actuation states, enhancing user understanding of mecanum wheel kinematics. This implementation successfully demonstrates the effective use of teleoperation of a mecanum wheel robot actuation as platform for interactive STEM education, providing hands-on experience in robotics actuation, IoT protocols, control systems, and mobile application development.
