"Seiring dengan perkembangan jaman, kebutuhan manusia semakin meningkat dan teknologi semakin berkembang, hal ini juga akan mempengaruhi tingkat permintaan akan tenaga listrik. Kebutuhan listrik masyarakat Indonesia semakin meningkat setiap tahunnya, menurut RUPTL (Rencana Usaha Penyediaan Tenaga Listrik) PT. PLN 2013-2022, konsumsi listrik Indonesia diperkirakan akan meningkat dari 189 TWh pada tahun 2013 menjadi 386 TWh pada tahun 2022. Untuk itu, dimungkinkan memberikan kesempatan pada pihak ketiga non-IPP untuk membangun dan menyediakan listrik dengan melalui skema power wheeling. Power wheeling merupakan pemanfaatan suatu jaringan tenaga listrik oleh penyedia listrik lain sebagai suatu alternatif permasalahan penyediaan pasokan serta keandalan sistem tenaga listrik. Terdapat beberapa metode yang dapat diterapkan pada pemanfaatan bersama jaringan transmisi (PBJT), namun dalam hal ini penulis menggunakan metode MVA-Mile dan Postage Stamp untuk diterapkan pada jalur transmisi 150 kV dan 500 kV pada area Jakarta-Banten dengan menganalisis beberapa permasalahan yang ada pada sistem jaringan transmisi tersebut. Dengan jarak penghantar daya yang sama, penggunaan jalur transmisi 500 kV dan 150 kV dalam penyaluran daya memiliki tingkat efisiensi yang lebih tinggi dibandingkan dengan hanya menggunakan jalur transmisi 150 kV, namun pada sistem yang hanya menggunakan jalur 150 kV lebih mudah dalam perhitungan biaya transmisi.

Along with the development, human needs are increasing and technology is growing, it will also affect the level of demand for electric power. The electricity needs of the people of Indonesia is increasing every year, according to RUPTL (Electrical Power Supply Business Plan) PT. PLN 2013-2022, Indonesia's electricity consumption is expected to increase from 189 TWh in 2013 to 386 TWh in 2022. To that end, it is possible provide opportunities for third-party non-IPP to build and provides electricity to power wheeling through the scheme. Power wheeling is the use of an electric power network by another electricity provider as an alternative to the provision of supply problems and power system reliability. There are several methods that can be applied to the joint utilization of the transmission network (PBJT), but in this case the authors use the method of MVA-Mile and the Postage Stamp to be applied to the transmission lines of 150 kV and 500 kV in the area of Jakarta, Banten by analyzing some of the problems that exist in The transmission network system. With the same power conductor spacing, use of transmission lines of 500 kV and 150 kV in the transmission of power has a higher degree of efficiency compared to only use 150 kV transmission lines, but in a system that only uses 150 kV lines easier in the calculation of transmission cost.

"This book offers a concise introduction to the analysis of electrical transients aimed at students who have completed introductory circuits and freshman calculus courses. While it is written under the assumption that these students are encountering transient electrical circuits for the first time, the mathematical and physical theory is not ‘watered-down.’ That is, the analysis of both lumped and continuous (transmission line) parameter circuits is performed with the use of differential equations (both ordinary and partial) in the time domain, and the Laplace transform. The transform is fully developed in the book for readers who are not assumed to have seen it before. The use of singular time functions (unit step and impulse) is addressed and illustrated through detailed examples.
The appearance of paradoxical circuit situations, often ignored in many textbooks (because they are, perhaps, considered ‘difficult’ to explain) is fully embraced as an opportunity to challenge students. In addition, historical commentary is included throughout the book, to combat the misconception that the material in engineering textbooks was found engraved on Biblical stones, rather than painstakingly discovered by people of genius who often went down many wrong paths before finding the right one. MATLAB® is used throughout the book, with simple codes to quickly and easily generate transient response curves."

"This book addresses the design challenges in near-field wireless power transfer (WPT) systems, such as high efficiency, compact size, and long transmission range. It presents new low-profile designs for the TX/RX structures using different shapes of defected ground structures (DGS) like (H, semi-H, and spiral-strips DGS). Most near-field WPT systems depend on magnetic resonant coupling (MRC) using 3-D wire loops or helical antennas, which are often bulky. This, in turn, poses technical difficulties in their application in small electronic devices and biomedical implants. To obtain compact structures, printed spiral coils (PSCs) have recently emerged as a candidate for low-profile WPT systems. However, most of the MRC WPT systems that use PSCs have limitations in the maximum achievable efficiency due to the feeding method. Inductive feeding constrains the geometric dimensions of the main transmitting (TX)/receiving (RX) resonators, which do not achieve the maximum achievable unloaded quality factor. This book will be of interest to researchers and professionals working on WPT-related problems."

"Sebagai perusahaan listrik milik negara, PT PLN persero berusaha untuk menyuplai energi listrik secara optimal. Untuk menjaga kualitas energi listrik yang disalurkan, sistem pengaman dan pemeliharaan perlatan listrik suatu gardu induk sangat diperlukan. Pengujian pada transformator dilakukan untuk menjaga durability dan reliability dari sebuah sistem tenaga listrik terutama transformator daya yang berperan penting dalam penyaluran tenaga listrik. Untuk itu diperlukan pengujian transformator daya secara berkala. Sehingga jika ditemukan ketidaknormalan pada suatu transformator, dapat segera dilakukan penyelidikan lebih lanjut. Dengan demikian tidak akan terjadi kegagalan saat transformator beroperasi.

As state-owned enterprises, PT PLN persero manage to supply the electric energy optimally. In order to utilize and maintain the quality of the electrical energy, a system of maintenance and protection of substation electrical equipment are required. Transformer testing performed to maintain the durability and reliability of power system, especially power transformers that have an important role in the distribution of electricity. Therefor, periodic testing of power transformer is needed, so that in case there is an abnormality on the transformer, a further investigation can be done immediately. thus the failure of the transformer during operation can be avoided."

"ABSTRAK
Band Pass Filter (BPF) memiliki peran penting dalam banyak aplikasi Radio
Frekuensi (RF). BPF digunakan untuk memisahkan frekuensi yang berbeda. Hal ini
disebabkan Spektrum elektromagnetik merupakan sumberdaya terbatas sehingga
harus dibagi. BPF digunakan untuk memilih sinyal RF dalam frekuensi kerjanya.
Berbagai aplikasi komunikasi nirkabel terus muncul dan mengharapkan kinerja filter
RF dengan kinerja yang tinggi dan ukuran yang lebih kecil. Proyek ini mempelajari
prinsip mikro-strip bandpass RF filter. Metode yang digunakan Tangga dan Hairpin.
Jenis Chebysev dengan orde 5 dan ripple sebesar 0,01 dB. Sistem ini disimulasikan
dalam software Desain Advanced System (ADS), kemudian di pabrikasi dan diukur
untuk memvalidasi desain. Tujuan penelitian ini adalah untuk merancang Microstrip
filter bandpass untuk Automatic Dependent Surveilance Broadcast (ADS-B)
dengan Frekuensi Pusat 1090 MHz menggunakan Ladder dan Metode Hairpin dan
kemudian membandingkan kedua metode untuk memperoleh kinerja yang lebih
tinggi dan ukuran yang lebih kecil.

ABSTRACT
Band Pass Filters has an important role in many Radio Frequency (RF) applications.
They are used to separate different frequencies. The electromagnetic spectrum is
limited and has to be shared; filters are used to select the RF signals within assigned
spectral limits. Emerging applications such as wireless communications continue to
challenge RF filters with ever more stringent requirements—higher performance and
smaller size. This project studied the principle of micro-strip RF bandpass filter. The
method used the Ladder and Hairpin. The Chebysev type with order 5 and ripple of
0.01 dB was used. The system is simulated in software Advanced Design System
(ADS), fabricated and measured for validate the design. The objectives are to
design Micro-strip bandpass filter for Automatic Dependent Surveilance Broadcast
(ADS-B) with Frequency Center 1090 MHz using Ladder and Hairpin Method and
then compare the both methods for obtain higher performance and smaller size."
