Abstract

Modul reaktor alir tangki berpengaduk (RATB) bench scale adalah suatu perangkat reaktor untuk reaksi kimia yang spesifikasi teknisnya diperoleh dari hasil desain dengan mengadopsi kaidah desain RATB namun dengan ukuran desain yang kecil (volume 1000 mL) yang dilengkapi dengan sistem pengatur debit dan kecepatan pengadukan serta pengendali temperatur. Tujuan penelitian ini adalah melakukan uji fungsi pengatur debit dan pengendali temperatur pada modul RATB bench scale gelas untuk persiapan sintesis zirconium basic sulphate (ZBS) - Zr5O8(SO4)2.15H2O berdasarkan karakteristik perubahan volume dan temperatur fluida yang terukur dalam reaktor. Metode yang dilakukan diawali dengan kalibrasi pompa dosis sebagai pengukur kecepatan alir larutan ZrOCl2, reaktan (NH4)2SO4, dan slurry ZBS. Kemudian dari data debit fluida dilakukan percobaan pengaruh waktu tinggal fluida (60, 75, 90, 105, 120 menit) dan kecepatan pengadukan fluida (100, 200, 250, 300 rpm) terhadap penyimpangan volume dan temperatur fluida terukur dari data desain modul RATB bench scale dengan volume 1000 mL dan temperatur 90 oC. Hasil penelitian menunjukkan bahwa pada percobaan pengaruh waktu tinggal dan kecepatan pengadukan memberikan rentang volume fluida 900 – 1030 mL atau dengan penyimpangan volume fluida 0 – 5 % dan rentang temperatur fluida di dalam reaktor 89,0 – 92,6 oC atau dengan penyimpangan temperatur fluida 1,1 – 2,8 %. Berdasarkan data penyimpangan volume dan temperatur fluida terukur yang < 10 %, maka dapat disimpulkan bahwa alat pengatur debit dan pengendali temperatur pada RATB bench scale memiliki kinerja yang baik.

Abstract

The monitoring system for temperature, humidity and air pressure in the electron accelerator’s room has been designed. This research is based on operational environmental monitoring procedures in the accelerator room that must be carried out before the accelerator operates. We offer a simple and adaptable monitoring solution for the electron accelerator room. Parameter data can be monitored using a smart device. Operators do not need to go into the accelerator room to carry out environmental monitoring. The proposed system uses Arduino technology and the Internet of Things (IoT). Data acquisition programming was performed using Arduino IDE and ESP8266 NodeMCU as microcontrollers. The microcontroller then transmits temperature, humidity, and pressure data parameters to the cloud server, where they are then displayed on the smart device via the Blynk app. The results show that the system that has been designed is able to read and store parameter readings on the sensors used and the system has been able to make decisions in the form of notifications about whether the Electron Beam Machine is ready or not to be operated.

Abstract

An improved design of the conveyor system of Arjuna 1.0 electron accelerator for 3D object irradiation has been done. The penetration of low energy electrons is less than 1 cm in the surface, causing a challenge for the irradiation process for sterilization of 3D objects. We design a conveyor that can be rotated 360o to irradiate objects evenly. The dimension of this conveyor is 1750 x 600 x 800 mm and the maximum diameter of the object is 7 cm. Based on the Frame Bending Stress analysis to calculate the strength of the conveyor frame, it is shown that the maximum displacement is only 0.029 mm, which is very small so it will cause no disturbance to power transfer from the motor to the conveyor. The normal stress (Smax) is 3.926 MPa and the bending stress for Smax (Mx) and Smax (My), are 2.391 MPa and 3.925 MPa respectively. We also calculate the stress analysis of the 3 mm-thickness of the motor mount and found that the Von-Misses Stress, first, and third Principal Stress are 4.425 MPa, 5.01 MPa, and 1.95 MPa respectively. These results confirm that the design and the material used for the conveyor are safe because the stress is very low than the material’s yield strength which is 207 MPa. The power needed for this conveyor is 0.01724 kW, with a maximum speed is 880 rpm. The new model of 3D conveyor has been constructed and can be implemented to ARJUNA 1.0 to irradiate objects on all its surfaces

Abstract

Particle accelerators receive significant attention from researchers. This machine consists of various interdependent elements, so it is complex. Efficient system tuning and diagnostics are essential for utilizing accelerator technology. In addition, machine learning (ML) has been applied in several applications. ML methods such as artificial neural networks, random forest, reinforcement learning, genetic algorithm, and Bayesian optimization have been used for accelerator optimization. The optimization of particle accelerators covers their performance and efficiency. This paper reviews the application of ML techniques in optimizing particle accelerators, highlighting their importance in addressing the complexity inherent in accelerator systems and advancing accelerator science and technology.
