"One of the great pioneers of electrical science, Oliver Heaviside (1850-1925) was a self-educated, fiercely independent genius who cared nothing for social or mathematical conventions. Among many achievements, he showed how to rid telephone lines of distortion and put Maxwell's wonderful but hitherto inaccessible theory of electromagnetism into its modern form. In his writings, and in life, he was always provocative, often amusing, sometimes infuriating, but never dull.This is a compelling account of Heaviside's life with a powerful insight into his scientific thinking and why it has been so influential."

"Sistem Ereke merupakan sistem kelistrikan di kawasan sisi utara pulau Buton yang masuk wilayah Kabupaten Buton Utara. Namun pola operasi pada sistem Ereke dipasok dari sistem Baubau dan dalam beberapa kondisi dioperasikan secara isolated. Dari pola operasi tersebut, terjadi beberapa kondisi yaitu kualitas tegangan yang buruk akibat letak geografis Ereke dan Baubau terlampau jauh ±199,1 kms, kemudian apabila terjadi padam meluas/padam total (Blackout) proses penormalan pada sistem Ereke membutuhkan waktu yang cukup lama karena kondisi Ereke yang berada di ujung jaringan dan tercatat pada tahun 2021, sistem Ereke mengalami padam total sebanyak 63 kali. Dari hasil analisis diperoleh bahwa apabila menggunakan pola operasi dipasok dari sistem Baubau, maka biaya yang dibutuhkan sebesar Rp 1.159.452.493,9/bulan dengan tegangan pangkal 15,6 kV pada pelanggan serta lamanya pemulihan pasca padam meluas/padam total dan apabila isolated Rp 1.622.262.413,2/bulan dengan tegangan pangkal 19,7 kV namun biaya lebih mahal namun dapat mengurangi lama waktu pemulihan pasca gangguan karena jaringan lebih pendek dan rugi jaringan berkurang. Selain itu, nilai SAIDI pada bulan Mei 2021 yaitu 5,03 jam/pelanggan/tahun dan SAIFI 5,97 kali/pelanggan/tahun. Dengan demikian, pilihan terbaik dalam pengembangan sistem pembangkitan di Ereke adalah dengan membangun sistem Ereke interkoneksi dengan sistem Baubau dengan disertai dengan pembangunan sejumlah penyulang untuk menaikkan kualitas tegangan dan kehandalan sistem Ereke dan menggunakan simulasi pada software DigSilent. Semua analisa mempertimbangkan RUPTL terbaru tahun 2021-2030.

The Ereke system was an electrical system used on the northern Buton island, a part of the North Buton Regency. The operating methods on the Ereke system were the operation method which was supplied from Baubau system and, in some conditions, isolated operation. There were several conditions caused by those operating methods, which were the poor voltage quality due to the geographical distance from Ereke to Baubau that were too far (±199,1 kms) and the long duration of the normalization process if there was a widespread blackout since Ereke was located at end of the network. In addition, the Ereke system experienced a total of 63 outages in 2021. From the analysis result, it was obtained that the operating method which was supplied from the Baubau system will cost Rp. 1,159,452,439.9/month with 15.6 kV base voltage and a long normalization duration after blackout/total blackout. On the other hand, it was also obtained that the isolated operation method will cost Rp. 1,622,262,413.2/month with 19.7 kV base voltage which was more expensive but with a shorter normalization duration after interruptions due to shorter network and the decreased network loss. Otherwise, the SAIDI value in May 2021 is 5.03 hours/customer/year and SAIFI 5.97 times/customer/year Therefore, developing interconnection of Ereke system and Baubau system along with the constructions of feeders to increase the voltage quality and reliability also with the use of DigSilent simulation software will improve the quality of electrical generation development in Ereke. The latest RUPTL (2021-2030) was considered through every analysis."

"Dilakukan perancangan dan pengembangan sistem pengukuran arus inverter 3 fasa, tegangan DC-Link, posisi sudut rotor, dan kecepatan sudut rotor menggunakan modulator sigma-delta terisolasi, absolute encoder, dan incremental encoder. Dilakukan pembandingan hasil pembacaan arus dan tegangan oleh sensor yang dikembangkan dengan arus dan tegangan yang didapatkan dari osiloskop. Didapatkan MAEArusFasaA = 0.510594 A, MAEArusFasaB = 0.71434 A, MAEArusFasaC = 0.710017 A, dan MAETeganganFasaA-N = 30.35317 V. Meskipun tidak dapat diimplementasikan ke dalam sistem, algoritma pembacaan sudut as menggunakan absolute encoder berhasil melakukan pembacaan sudut as, dibuktikan dengan pembandingan grafik sudut as yang dibentuk oleh incremental encoder. Dikemukakan pula kemungkinan alasan kegagalan integrasi absolute encoder tersebut pada bagian analisis.

Design and development of a 3-phase inverter current measurement, DC-Link voltage, rotor angular position, and rotor angular speed system using isolated sigma-delta modulator, absolute encoder, and incremental encoder has been conducted. The results of current and voltage readings by the developed sensor modules are compared with the current and voltage obtained from the oscilloscope. Performance parameters is obtained with MAEArusFasaA = 0.510594 A, MAEArusFasaB = 0.71434 A, MAEArusFasaC = 0.710017 A, dan MAETeganganFasaA-N = 30.35317 V. Although it cannot be implemented into the system, the algorithm for reading the shaft angular position using an absolute encoder in reading the angular position has been performed as showed by the comparison of angular position graph generated by the incremental encoder. The possible reasons for the failure of the absolute encoder integration has been proposed in the analysis section."

Saat ini, listrik merupakan sumber daya yang sangat penting untuk semua orang dalam menunjang aktivitas sehari-hari yang mereka lakukan. Masyarakat dimudahkan dengan banyaknya metode pembayaran tagihan listrik yang bisa mereka pilih. Pada skripsi ini dilakukan penggunaan teknologi Blockchain dalam sistem pembayaran tagihan listrik. Teknologi Blockchain adalah teknologi yang memungkinkan transaksi dilakukan secara terdesentralisasi, transparan, dan aman. Dalam skripsi ini dijelaskan secara sederhana tentang teknologi Blockchain serta bagaimana teknologi ini dapat diterapkan dalam sistem pembayaran tagihan listrik di indonesia dengan membuat sebuah situs web yang dapat digunakan oleh pengguna untuk melakukan pembayaran tagihan listrik elektronik berbasis Blockchain dengan Ethereum sebagai jaringan blockchain yang digunakan. Dari 3 pilihan gas fee yang diujikan sebanyak 10x percobaan, pilihan “aggressive” adalah pilihan yang tepat apabila pengguna ingin proses transaksi yang cepat (4.5s), pilihan “market” cocok untuk pengguna yang baru pertama kali mencoba dan ingin mengikuti standar yang telah ditetapkan oleh metamask (9.4s). Pilihan “low” adalah pilihan yang paling nyaman para pengguna yang mengutamakan fungsi dan tidak mementingkan kecepatan transaksi (18.8s).

Nowadays, electricity is a very important resource for everyone to support their daily activities. People are facilitated by the various methods to pay electricity bills that are available for them. In this research, Blockchain technology is used in the electricity bill payment system. Blockchain technology is a technology that allows transactions to be carried out in a decentralized, transparent, and secure manner. This research explained about Blockchain technology and how this technology can be applied in the electricity bill payment system in Indonesia by creating a website that can be used by users to pay their electricity bills with Ethereum as the blockchain network. Of the three gas fee options tested, “aggressive” option is the right choice if users want a fast transaction process (4.5s), “market” option is suitable for first-time users and wants to follow the standards set by metamask (9.4s). The “low” option is the most comfortable choice for users who prioritize function and are less concerned with transaction speed (18.8s)."

"A properly co-ordinated protection system is vital to ensure that an electricity distribution network can operate within preset requirements for safety for individual items of equipment, staff and public, and the network overall. Suitable and reliable equipment should be installed on all circuits and electrical equipment and to do this, protective relays are used to initiate the isolation of faulted sections of a network in order to maintain supplies elsewhere on the system. This then leads to an improved electricity service with better continuity and quality of supply.Written by two practising electrical engineers, this second edition of the best selling Protection of Electricity Distribution Networks (IEE, 1998) offers both practical and theoretical coverage of the technologies, from the classical electromechanical relays to the new numerical types which protect equipment on networks and in electrical plant."
