Abstract

A computational calculation to determine production capacity of 90Y from the results of nuclearreactions 89Rb(p,n)89Sr/90Y from several medical cyclotrons has been carried out. Calculations were used to obtain the target thickness of 89Rb and maximum activity of 90Y on variable energy, time and irradiation currents. Calculations were also carried out to measure the impurity radionuclide activity during the reaction. The results activities of 90Y were obtained through modeling using the SRIM-2013 software and the TENDL-2017 application and calculated using MATLAB software. The results modeling and of calculations can predict the activity of 90Y and it can be used as an initial reference in the radionuclide production process using a cyclotron. The maximum activity of 90Y of 5409.80 mCi with a 10.54 mm-target thickness of 89Rb is generated from a cyclotron which has a 30 MeV proton beam with a 50 μA radiation current beam and 2 hours irradiation time. Using the same proton, current and irradiation time at irradiation energy of 8 MeV, 15 MeV and 22 MeV, the produced activity of 90Y was smaller, there are 552.28 mCi, 2100.39 mCi and 3644.31 mCi. The radioisotope of 90Y can be used in patients with a normal dose of 0.4 mCi / kg body weight, therefore in one production can supply the needs of 104 patients.Keywords: medical cyclotron, calculation and modeling, 90Y activity

Abstract

Computed tomography (CT) merupakan suatu alat yang digunakan untuk mendapatkan citra tubuh pasien untuk mendiagnosis berbagai penyakit. Tujuan penilitian ini adalah mengotomasi posisi meja pasien CT scan menggunakan kamera Kinect berbasis Mikro-kontroler ATmega 328p sesuai ukuran tubuh pasien. Mikro-kontroler ATmega 328p digunakan sebagai pusat kendali otomatis dalam menggerakkan meja pasien ke atas-bawah sehingga posisi tengah pasien tepat berada pada iso-center. Adapun Mikro-kontroler mendapt input dari perbedaan posisi center pasien dan iso-center pesawat CT yang diperoleh dari citra yang dihasilkan oleh kamera Kinect. Penelitian ini telah berhasil merealisasi sistem otomatisasi posisi meja CT yang dapat dinaikkan dan diturunkan secara otomatis dan dikendalikan berdasarkan input dari kamera Kinect. Meja pasien CT bergerak naik 1 cm untuk setiap empat kali putaran motor. Meja dapat begerak hingga batas maksimal sejauh 15 cm.Kata Kunci: CT, meja pasien, mikro-kontroler, kamera Kinect, patient center, gearbox.

Abstract

The purpose of this researh is to analyze a crystalinity and size of zinc oxide (ZnO) nanoparticles. ZnO nanoparticles were synthesized using precipitation method followed by ultrasonic radiation. Precipitation products were calcined at temperature of 100oC and 200oC. ZnO nanoparticles were characterized using X-Ray Diffractometer (XRD) and Scanning Electron Microscope (SEM). The XRD pattern showed formation of ZnO nanoparticles with wurtzite hexagonal structure. ZnO nanoparticles with crystalinity higher than 50% was obtained at calcination temperature of 200oC. ZnO nanoparticles composed by a collection of crystallites that form spherical particle with size in the range 150–250 nm.Keywords: zinc oxide, nanoparticles, precipitation, crystal structure, crystallinity

Abstract

The aim of this research is to design and to implement a computer numerical control (CNC) machine using a cellular phone through bluetooth networks for drawing on a two-dimensional (2D) area of 40 mm x 40 mm. The machine consisted of several main parts, including DVD motor stepper, L293D, servo motor, HC-05, and cellular phone. The control was carried out by using the Blynk application that can be used in two modes, namely automatic (G-code based) and manual modes. The capability of the machine to draw test images were carried out, including linear motion, circular motion, up and down motion, displaying menu, rectangle shape, triangle shape, and circular shape. Results show that the CNC machine can move to draw images according to the commands given in each command mode.Keywords: CNC, Cellular phone, Bluetooth, Blynk

Abstract

The aim of this study is to develop an automatic drilling machine based on Atmega328integrated with the 3.2 inch-Nextion LCD Touchscreen. The drilling machine was designed to automatically determine the distance and the number of holes according to the LCD touchscreen nextion display, both for movement on the Y-axis and X-axis, using a PH268-21 series unipolar of stepper motor and was controlled by a CSD2120P type motor driver. Meanwhile, to perforate the workpiece using an AC motor with a voltage of 220 volts. Machine control used 2 Limit Switches as calculation indicators to be processed by a microcontroller that has been programmed using the Arduino IDE software and displayed on the Nextion LCD touchscreen. From the test it was found that this automation system is very accurate to produce number of holes. The accuracy of distance used as an initial indicator of this automatic drilling machine was 1 mm and it can be changed according to desired needs. Therefore, this automatic drilling machine can provide more effective and efficient results so that it is expected to help in maximizing results for industrial-scale.Keywords: limit switch, unipolar stepper motor, micro-controller, Nextion LCD touchscreen
