Di era modern seperti saat ini, energi listrik memegang peranan penting dalam kehidupan. Saat ini energi listrik pada umumnya diperoleh dari sistem pembangkit berbahan bakar fosil dan gas yang merupakan energi tidak dapat diperbarui. Disamping itu, polusi udara yang diakibatkan oleh gas sisa hasil pembakaran sudah dalam tahap memprihatinkan, keterbatasan penggunaan enegri ini memaksa para ilmuw…
In this study, an evaluation of the lightning protection system was carried out at PT. PLN (PERSERO) UP2D S2JB Palembang, namely the Base Transceiver Station (BTS) tower, Office building, Operation & Maintance Electrical Distribution System Campus building and Yantek Ampera building using electrogeometric methods. In the calculation results obtained a peak lightning current of 54.360 and a stri…
The major emphasis of this book is on physical mechanisms and sources of the ULF/ELF natural electromagnetic fields noises. In the course of this text, some of these mechanisms of magnetospheric origin will be treated in detail and others in a more sketchy fashion, while the global electromagnetic resonances excited by lightning activity and other sources are the priority. The interested reader…
Schumann resonance has been studied for more than half a century. The field became popular among researchers of the terrestrial environment using natural sources of electromagnetic radiation—lightning strokes, primarily—and now many Schumann observatories have been established around the world. A huge number of publications can be found in the literature, the most recent collection of which…
Penggunaan batu bara Indonesia didominasi oleh hard coal yang diproyeksikan sebagai sumber energi utama (±25%) pada 2050. Batu bara peringkat rendah digunakan sebagai pengganti hard coal melalui proses Upgrading Brown Coal (UBC). Teknologi UBC bertujuan untuk meningkatkan nilai kalor batubara dengan cara meningkatkan C/H ratio yang ada pada batubara, serta dapat mengurangi jumlah pemakaia…
