Linac radiotherapy measurentoften experience instability. One of the irradiation errors with Linac can occur because the radiation beam that comes out is not expected properly. Determination of the correction factor and linearity is important to analyze the charge output of the electron energy emitted by Linac's modality to see the stability of the emitted charge. This study uses Electron Linear Accelerator Electron beam daily output data with a 10 cm × 10 cm applicator, 100 cm SSD, 0.125 cc cylindrical ionization detector PTW type 31010 Semiflek and uses a slab solid phantom with energy variations of 6 MeV, 8 MeV, 10 MeV, 12 MeV and 15 MeV. The measurement results are calculated using the IAEA TRS 398 protocol. The result of linearity correction factor of 96.87% which shows the stability value of the electron beam load output is very good, and the results of the correction factor show the enumeration values of each energy 6 MeV, 8 MeV, 10 MeV, 12 MeV and 15 MeV namely 0.030342129 nC, 0.03034 nC, 0.03034 nC, 0.03034 nC and 0.03034 nC values respectively still within the tolerance range of measurement ± 1. The correction factor that has been obtained is used as a parameter in calculating the absorbance dose to the maximum depth.

This study is aimed to numerically and experimentally investigate the magnetic field dynamics in hemisphericalelectrodes plasma focus. We have initiated the numerical magnetic field propagation by finite differenceapproach with Taylor expansion for the purpose of each distribution to plasma focus medium but not specifiedfor hemispherical electrodes design. Although the magnetic field profile is still in arbitrary numbers, this modelcan simply be used to compare with the experimental results. The absorption and attenuation of magnetic fieldare affected by the plasma medium mainly the production of electron and charged particle movement. However,the code generated for magnetic field attenuation is assumed for dimension and time dependant only.

Proses kelistrikan ini menggunakan elektroda grafit pensil yang digunakan untuk melucuti gas pembentukan plasma dengan metode electrical-discharge pada rentang tekanan atmosfir. Plasma Karbon diproduksi dengan mengoperasikan tegangan (DC)<3,5kV dan mengalirkan gas butana ke dalam tabung plasma. Hasil eksperimen menunjukkan tegangan jatuh dan arus listrik. Tegangan dan arus listrik diperoleh sebelum dan sesudah terjadi breakdown. Densitas dan temperatur plasma Karbon dihitung dari arus listrik dan tegangan jatuh. Hasil eksperimen menunjukkan ionisasi udara pada tekanan rendah memiliki tegangan maksimum 570V, tegangan jatuh 530-570V dan arus listrik 0,27-0,45mA, sedangkan pada tekanan tinggi memiliki tegangan maksimum 1160V, tegangan jatuh 900-1100V dan arus 0,46-0,6mA. Ionisasi yang terjadi saat penambahan gas butana (ketidakmurnian campuran udara) pada tekanan rendah memiliki tegangan maksimum 772V, tegangan jatuh 536-775V dan arus listrik 0,03-0,45mA, sedangkan pada tekanan tinggi memiliki tegangan maksimum 1044V, tegangan jatuh 675-1055V dan arus listrik 0,03-0,69mA.

Helium plasma source modelling was performed in order to obtain species density at balanced conditions under pressure of 1 atm. The software used in this modelling is matrix laboratory software (MATLAB). The equation used is a continuity equation that depends on the position and parameters of Arrhenius. Plasma temperatures used were 0.1 eV, 0.2 eV, 0.3 eV, and 0.5 eV. Species involved in a plasma consist of electrons, He, He+, He2+, He*, and He2*. The modelling results showed that the density value of He species increases as temperature increases. It is noted that the obtained the density of He (nHe) when reaching a balanced condition at the temperature of T = 0.1, 0.2, 0.3, and 0.5 are 3.0137 × 1025, 7.9506 × 1026, nHe = 1.6489 × 1028, and 7.1384 × 1029, respectively. This is because He is a noble gas that is monatomic and chemically inert. Thus resulting in stable plasma production and gaining an increase in density value. Plasma-charged species are the main media that cause the disinfection of microorganisms because they can break the hydrogen bond of the organic molecules that make up the dental plaque. So the influence of charged species when applied to dental plaque has more effective than that of neutral reactive species.

The density and reaction rate values of plasma are physical quantities needed to produce plasma hydrogen. Both are needed to estimate the heat and the operating time of plasma generator. Density and reaction rate of plasma values are obtained by computational modeling using the continuity and Arrhenius equation. Five spesies of hydrogen are used in this research i.e electron, H2, H2+, H and H+. The pressure used was 9.7 mTorr and the temperature of electron used is higher than the temperatures of the hydrogen species. The temperatures scale used in high at 34812 Kelvin for electron and 9283.2 for other species. The study resulted that hydrogen gas can be plasma when it reaches the time span 3.8x10-7second. The equilibrium conditions last for 10-3 second after the time limit be returned as plasma gas. The result of density for each species at range 1016 until 1018 m-3. The value of the fastest reaction rate equal to 7,3 x 1053 m-3 s-1.

The ion carbon species are massively produced througharc plasma for synthesizing carbon nanotube. Positive ions would have tendencies to move towards the negative charged cathode. The moving of the massive ions generated electric field in direction parallel with the ion movement. In this paper, we discuss the particle collisions subsequently resulting a new carbon species namely carbon nanotube (CNT) composed from single/many graphene layer rolled up alike nanostraw structure.

Pendeteksian jantung masih terus berkembang karena persoalannya serius terhadap perilaku hidup manusia sehingga perlu upaya untuk mencari jalan lain untuk lebih mudah mendeteksi jantung. Saat ini pendeteksian jantung dapat dilakukan tanpa harus pergi ke rumah sakit seperti dengan menggunakan ponsel, jam tangan, dan lain-lain. Fiber Bragg Grating (FBG) banyak juga digunakan untuk mendeteksi jantung, karena bisa diterima dalam bentuk tekanan yang mengakibatkan terjadinya perubahan regangan. FBG dipilih karena memiliki sensitivitas yang tinggi terhadap regangan. Pendeteksian denyut jantung dapat dilakukan dengan beberapa cara seperti menggunakan teleskop, namun dengan menggunakan FBG memiliki tingkat akurasi yang tinggi dan sensitif terhadap regangan. Penelitian ini bertujuan untuk merancang dan mengukur perubahan daya keluaran pada FBG serta menganalisa pengaruh perubahan regangan pada FBG oleh getaran loudspeaker. Panjang gelombang Bragg yang digunakan adalah 1310 nm dan 1550 nm dengan daya 1 mW sebagai sumber laser dioda serta keluaran diukur dengan optical power meter. Perubahan daya keluaran tertinggi pada panjang gelombang Bragg 1310 nm senilai dengan 0,736 µW, sedangkan pada panjang gelombang 1550 nm senilai dengan 0,009 µW. Pergeseran panjang gelombang Bragg tertinggi pada panjang gelombang Bragg 1310 nm senilai 0,598 nm, sedangkan pada panjang gelombang Bragg 1550 nm senilai 0,552 nm. Perubahan regangan tertinggi pada panjang gelombang Bragg 1310 nm senilai 576,186 µε, sedangkan pada panjang gelombang Bragg 1550 nm senilai 432,113 µε. Ini menunjukkan bahwa respon pada panjang gelombang Bragg 1310 nm lebih sensitif daripada panjang gelombang Bragg 1550 nm.
