Abstract

This research aimed to design the KvP meter for checking the error of output voltage from X-Ray machine with the range of 50-70 KvP. It used Arduino Gelatino microcontroller programmed with Arduino IDE software as data processor of detector result. The detector was designed based on the physics principle using material attenuation coefficient namely aluminum whose good effect in reducing the energy level of X-ray photons. Thus, the photodiode sensor only read the effective energy of the X-ray energy. Based on the radiation intensity ratio through the aluminum filter with 0.25 mm and 0.5 mm thickness, it is better to measure X-ray tube voltage non-invasively The KvP Meter was tested by setting duration of X-ray exposure that was 0.3 second, tube current was 10 mA, and KvP Meter distance from collimator was 90 cm. A prototype unit was made, and the performance was tested in terms of error and precision. After testing and analyzing the data, the error result was less than 5.1% with the highest measurement precision of ± 1.50.  It is generally concluded that this equipment can be used to measure the voltage of the X-ray tube.

Abstract

ABSTRAKOxygen analyzer sebelumnya hanya dilengkapi dengan penyimpanan data internal dengan maksimal penyimpanan 10 data. Berdasarkan permasalahan tersebut, dibuatlah oxygen analyzer untuk mengukur kadar oksigen pada output gas medis dengan parameter kadar oksigen (%) dilengkapi dengan penyimpanan data eksternal yang bisa menyimpan banyak data untuk keperluan kalibrasi peralatan dan pengecekan kevalidan dari kadar oksigen yang diberikan ke pasien sehingga data perlu disimpan dengan baik tanpa dicatat satu persatu tapi otomatis tersimpan pada memori eksternal yang bisa dipindah ke komputer. Untuk mengukur kadar oksigen pada output gas medis digunakan sensor oksigen tipe KE-50, dan mikrokontroler Arduino Uno. Setelah pengujian data, nilai error yang didapatkan berada di bawah 1% dan penyimpanan data eksternal berfungsi dengan baik.Kata kunci: Oksigen, Sensor Oksigen, Gas Medis, penyimpanan data, arduino ABSTRACTThe previous study designed an oxygen analyzer that was only equipped with internal data storage with a maximum of 10 data storage. Therefore a tool was made to measure oxygen levels at the output of medical gas with oxygen level parameters (%) equipped with external data storage that can store a lot of data for the purposes of equipment calibration and checking the validity of the oxygen level given to the patient so that the data needs to be stored neatly without needing to be recorded one by one but automatically stored in external memory that can be moved to the computer. To measure oxygen levels at the output of medical gas used the KE-50 type of oxygen sensor, and the Arduino Uno microcontroller. After testing the data, the error values obtained are below 1% and external data storage works properly.Keywords: Oxygen, Oxygen sensor, Medical gas, data storage, arduino

Abstract

Each device requires redundancy, including the X-ray machine. In an X-ray machine, there is an important component as the location for the creation of X-rays, namely the X-ray tube. This tube needs routine maintenance to increase the tube's lifetime. In addition, maintenance that was originally done manually, with this device can be done automatically and more quickly. In addition, maintenance that was originally done manually can be done automatically and faster with this device. X-ray tube oil vacuum is used as an effective solution for the maintenance of an X-ray tube machine that lasts for days. This device comes with easy use, equipped with two buttons and a display. This device can increase the productivity of both the device and the technician itself. The application of the use of X-ray tube oil vacuum is intended for hospitals and health facilities that have active X-ray machines. This device has been able to be built. Based on the results, it has a 2.5% error for the measurement at minimum and maximum pressure and a 3% error at -15 KPa pressure. The volume of the X-ray tube fully filled is always the same for each measurement. It can be concluded that this device can be effective in time because it only takes minutes to fill the X-ray tube up to full. Still, many parts can be improved and developed, such as the size and the weight.
