ABSTRAKKWh meter prabayar 1 phasa merupakan kWh meter elektronik dengan sistem pelanggan harus mendeposit kWh sebelum dapat menggunakan energi listrik. KWh meter prabayar memiliki tingkat akurasi yang lebih baik dibanding kWh meter elektromekanik dan tersusun atas sensor arus, sensor tegangan, rangkaian pengkondisi sinyal dan mikrokontroller. Sistem penginderaan arus menggunakan sistem double sensing pada phasa dan netral. Keluaran dari sensor arus akan dibandingkan dan diambil nilai tertinggi yang digunakan sebagai perhitungan energi listrik. KWh meter prabayar mampu mengukur hingga harmonisa ke-15 dan dilengkapi anti tempering. Fitur yang dimiliki kWh meter prabayar ini pada aplikasinya ditemukan permasalahan yaitu kWh meter tetap mengukur pada keadaan MCB off atau tanpa beban. Kejadian tersebut ditemukan pada pelanggan yang memasang sistem pentanahan (grounding) pada instalasi kWh meter dan instalasi bangunan. Dari permasalahan yang timbul tersebut maka perlu dilakukan penelitian pengaruh sistem pentanahan terhadap kesalahan pengukuran pada kWh meter prabayar.
ABSTRACTOne phase prepaid energy meter is an electronic energy meter with system customers must deposit kWh before customers can use electrical energy. Prepaid energy meter have an accuracy rate of better than electromechanical energy meters and is composed of the current sensor, voltage sensor, signal conditioning circuit and microcontroller. Current sensing system uses a system of double sensing the phase and neutral. The Output of the current sensor will be compared and taken the highest value is used as the energy calculations. Prepayment energy meter capable of measuring up to the 15th harmonic and equipped with anti tempering. Fitur owned prepayment energy meter is the application found that problems remain energy meter gauge on the condition MCB off or no load. The incident was found at customers who install the grounding system in energy meter installation and installation of the building. The problems arising from it is necessary to study the effect of the grounding system of the measurement errors on prepayment energy met, One phase prepaid energy meter is an electronic energy meter with system customers must deposit kWh before customers can use electrical energy.

ABSTRAKPertumbuhan penduduk yang tinggi menjadi faktor utama meningkatnya kebutuhan listrik di Indonesia. Kondisi fluktuasi beban yang sangat cepat ini harus diantisipasi dengan ketersediaan pembangkit yang memadai. Apabila beban meningkat tetapi suplai yang diberikan turun maka akan terjadi overload. Overload ini mengakibatkan suplai akan padam karena neraca suplai daya dengan beban tidak seimbang. Load shedding adalah metode tahapan pemisahan beban secara terencana untuk mengatasi terjadinya penurunan frekuensi yang disebabkan oleh kenaikan beban pada generator. Prioritas beban sangat berpengaruh terhadap tahapan load shedding.
ABSTRACTA high population growth has become a major factor from increasing electricity demand in Indonesia. The conditions of rapid load fluctuations must be anticipated by the availability of adequate power plant. If the load increases but the supply decreases there will be overloaded. The effect of this overload conditions will cause the supply is outages due to between supply and load is unbalanced. Load shedding is a method of unburdening stages planned to address the decline in frequency caused by the increase in the load on the generator. Load Priority greatly affect the load shedding stage"

"Seiring dengan pesatnya kebutuhan layanan multimedia semakin menuntut peningkatan bandwidth dan kehandalan jaringan yang memadai. Oleh karena itu PT Telkom Indonesia, Tbk melakukan perencanaan jaringan backbone DWDM 100 Gbps link Cirebon-Tegal guna memenuhi kebutuhan bandwidth tersebut. Pada perencanaannya dilakukan prediksi kebutuhan bandwidth dimasa yang akan datang. Berdasarkan keakuratan regresi linear yang hanya sampai 4 tahun, maka perhitungan prediksi dilakukan hanya sampai tahun 2017 dengan besar kapasitas yaitu 721.793 Gbps. Selain itu dilakukan kalkulasi level daya serta perhitungan BER untuk mengetahui performansi jaringan. BER yang diperoleh dari jaringan ini sebesar 4.48 x 10-31 sehingga dapat dikatakan bahwa jaringan ini memiliki performansi yang baik. Dari jaringan 100 Gbps ini pula diperoleh nilai tambah untuk segala bidang baik edukasi, kesejahteraan sosial hingga kemajuan teknologi selain itu nilai tambah yang dapat dihasilkan dari perencanaan jaringan 100 Gbps ini adalah penekanan biaya operasional serta pengurangan total loss yang terjadi selama pentransmisian.
Along with the increasing of multimedia services needs rapidly, it is adequate the increased bandwidth and network reliability. Therefore, PT Telkom Indonesia Tbk planning 100 Gbps DWDM backbone network for link Cirebon-Tegal to meet the bandwidth requirements. In the planning, the prediction bandwidth is one of requirements in the future . Based on the accuracy of linear regression that only up to 5 years , then the prediction calculation is performed only in 2017 with a large capacity is 721.793 Gbps. Moreover the power level and the BER calculation is needed to determine network’s performance. BER is obtained from this network is 4.48 x 10-31 so it can be said that this network has a good performance . From 100 Gbps network is also obtained value added to all areas such as education, social welfare until the advancement of technology besides these added values, other added value that can be generated from 100 Gbps network planning is operational cost reduction as well as reduction in the total loss that occurs during transmission."
