Karakterisasi Bolus Berbahan Campuran Beeswax dan Petroleum Jelly Menggunakan Berkas Elektron Pada Energi 6 MeV dan 9 MeV
Oleh: Adrial, Rico, Ningsih, Desy Yulia, Fadhilah, Zhafirah Putri
In radiotherapy cases of cancer on the surface of the skin generally use electron beams. The electron beam has not been able to provide the optimum surface radiation dose. Therefore, a material that is able to increase the dose of surface radiation is needed, which is called a bolus. This study test...

Peningkatan Fungsi Daun Chaya sebagai Agen Reduksi pada Sintesis Seng Nanopartikel
Oleh: suciayti, sri wahyu, Suprihatin, Suprihatin, Liani, Fegi
Nano-ZnO biosynthesis has been carried out using Chaya leaves with the addition of 0.7M NaOH. The aim is to determine the results of nano-ZnO synthesis regarding the formation of functional groups, phase structure, morphology, band gap energy, and its potential as an antibacterial. The synthesis pro...

Electric Field Controlled Anisotropic Rashba Splitting in Janus Chromium Dichalcogenide Monolayers : A Computational Study based on Density Functional Theory
Oleh: Anshory, Muhammad, Darojat, Yusron, Affandi, Yusuf
In this study, we explore the electronic structure of Janus Chromium Dichalcogenide monolayers CrXY (X ? Y = S, Se, Te) in the first Brillouin zone using Density Functional Theory. Due to the mirror symmetry break and strong SOC in the crystal structure of Janus Chromium Dichalcogenide monolayer, we...

Analisis Pengaruh Ukuran Lantai Muatan Timbangan Terhadap Nilai Error Pada Pengujian Eksentrisitas Timbangan Elektronik Sesuai OIML R76
Oleh: Muntoha, Geston Bakti, Erwanto, Danang, Afifah, Dian Septi Nur
The use of high-intensity non-automatic weighing instruments can cause users to overlook the load's location during weighing. However, electronic non-automatic weighing instruments maintain measurement accuracy regardless of the load's position. This study aims to analyze the effect of load recepto...

Dynamic Viscosity Measurement Method Based on the Stokes Drag of Prolate Ellipsoidal Mass
Oleh: Putra, Arifrahman Yustika, Yudiarsah, Efta, Sudarmaji, Arief
Viscometer plays an important role in the field of tribology. One way to measure viscosity is to use the Stokes drag principle in the underdamped harmonic oscillation phenomenon. This paper proposes a dynamic viscosity measurement method based on the related physical laws. Our experimental model inv...
