Solar activity is very important to be observed in order to study its effects to Earth's climate and space weather generally. In order to understand the behavior of the Sun and its activity, developing ground-based instruments is one of the ways to record the occurrence of the activity other than satellites data. We present in this paper our work on the implementation of Log Periodic Dipole Antenna (LPDA). The LPDA has been successfully set up at UiTM Shah Alam, Malaysia in 2016 with high performance with 8.4-meter height and it has achieved gain as high as 7.28 dB. It mainly records solar radio bursts during the occurrence of solar activity and has been operating at frequency range of 45-870 Hz. This project is done under International Space Weather Initiative (ISWI) by using CALLISTO spectrometer at the same frequency range to monitor solar observations in supporting developing countries with latest technologies of instrument. Beneficially in Malaysia, our station contributes half of the data on e-CALLISTO website due to 12 hours Sun exposure compared to other stations in different countries. All types of solar bursts obtained by e-CALISTO are presented in this paper. © 2021 Published under licence by IOP Publishing Ltd.
