Bermula dari kegemaran masyarakat akan konsumi sari buah yang siap saji dapat memberikan peluang yang sangat besar bagi para petani apel guna menigkatkan harga jual dari produk olahan mereka. akan tetapi proses pembuatan sari apel sendiri masih menggunakan proses manual, yakni pemerasan inti sari apel menggunakan kain sebagai medianya. Berdasarkan penelitian terdahulu terkait pengaturan kecepatan crusher motor dalam proses ekstraksi buah apel yang menggunakan metode PI masih belum menghasilkan kontrol waktu yang stabil, maka dari itu pada penelitian ini mengunakan fuzzy logic yang ditanamkan pada microcontroller sebagai kontrolernya dan sensor rotary encoder sebagai sensor kecepatannya. fuzzy terdiri dari Error dengan membersif function Kurang, Samadengan, Ples, DError adalah, - =, + dan memiliki Output lambat, sedang, cepat. Dengan set point 2000 RPM Chrusher dapat menstabilkan kecepatan motor chrasher terhadap variasi beban dari 1Kg dan 2 Kg. waktu tunda = 2 detik, waktu naik = 2 detik, waktu puncak = 3 detik, overshoot maksimal = 3.75%,error steasi state = 1,9% waktu setling = 3 detik. hasil dari respon sisten dihubungkan secara real time dengan HMI.

Tungku pemanas yang digunakan dengan ukuran diameter tungku 70 cm dengan tinggi 45.5 cm dan kapasitas 175 L. Suhu yang dikontrol pada tungku adalah 100°C - 115°C dengan menggunakan fine tuning diperoleh nilai Kp = 1.0 , Ti = 20.0 dan Td =0.00003. Hasil dari pengujian sistem kontrol suhu didapatkan efesiensi sistem 99.9%. Dan berdasarkan grafik respon sistem diperoleh karakteristik error steady state 0.3 – 0.7 % dan overshoot tidak lebih dari 1%. Dari parameter kontrol fine tuning PID tersebut, menunjukkan respon sistem yang baik dan mampu menjaga suhu sesuai dengan set point yang diberikan pada HMI.

It introduces a design of the control system for rehabilitation horse based on MCU STC89C52. The system’s control core is an 8-bit MCU STC89C52. First, the user input commands through the keyboard, then send commands to the DA conversion chip PCF8591 which can achieve the digital signal to analog signal output after dealing with MCU. Finally, PCF8591 send analog signal to the speed controller of DC motor in order to control the DC motor’s speed. Meanwhile, it builds a human-machine interface (HMI) to display the real-time speed of the horse through LCD.

Nuclear Power Plants (NPPs) are nowadays facing a transition from analog to digital control rooms, mainly in the form of new interfaces for displaying sensor information as of Human Machine Interface (HMI) were one-sided, taking into consideration either the human or the machine perspective. The approach presented in the present article considers human machine interfaces met in nuclear power plants as a joint system, where the performance of the NPP operator is evaluated according to the cooperation level achieved with the machine. In particular, the purpose of this study is to provide a methodology to evaluate the degree of flexibility of an operator during the transition period from an analog to a digital system. The proposed methodology has been implemented by utilizing fuzzy logic inference and realized with the fuzzy toolbox embedded in Matlab software.

Protective Relays

Engineering laboratories are key elements in engineering learning and are essential for a concrete understanding of engineering topics and experiments. These key laboratories are no longer just hardware-dependent, they are a creative combination of programmable hardware and also user-defined driving software. In this work, an educational power system protective relaying laboratory platform was designed and implemented using a programmable logic controller (PLC) and human–machine interface (HMI) in order to introduce engineering students to the operating mechanisms experimentally. It engaged the students in selecting settings and upgrading the inverse definite minimum time (IDMT) protection relays for overcurrent, overvoltage, undervoltage, and differential current. With the platform and the help of the HMI, the students mastered (or came close to mastering) the field of protective relays, especially those explicitly implemented in the platform. The students were also able to see the real-time response that is equivalent to the relay operation time of the protective relays under the various possible settings, and the kinesthetic learning that was involved gave them a deeper understanding of what is involved in relays upgrading.

Machine Interface

Process industries such as oil refineries, petrochemical plants, and power plants require a human-machine interface system to monitor continuously. The operator usually carries out monitoring via a human-machine interface. However, it is difficult to know the condition of process equipment in real-time. The implementation of augmented reality allows engineers to visualize process equipment in real-time when conducting field inspections. The implementation of augmented reality at the human-machine interface to the fluid catalytic cracking process in an oil refinery is discussed in this paper. The design was started by developing a three-dimensional process equipment model using Autodesk Inventor. The result of the three-dimensional model then using Unity 3D software connected to the Vuforia Engine was implemented on a gadget into an augmented reality application. Data communication performance analysis was carried out using inferential statistics methods to test variations in service quality at levels 0, 1, and 2. The result of the Tukey test showed that the communication network latency value in level 2 was significantly higher than levels 0 and 1, which was 0.704±0.108 seconds. These results indicate that augmented reality can be implemented on human-machine interfaces by ensuring the quality of data communication services using Message Queue Telemetry Transport (MQTT) protocol at levels 0 or 1.
