"In this paper an improved prediction-based power control is proposed for code division multiple access (CDMA) systems in Rayleigh fading channel environments. One of the most serious problems which degrades the performance of power control algorithm is the effect of feedback delay. To overcome the effect of feedback delay, power control needs to employ prediction algorithm which utilises the correlation property of the past channel samples measurementsto predict the future sample values. In CDMA power control, however, the correlation property of channel measurements is destroyed because the transmit power is continuously updated for each power control interval. The prediction algorithm in this paper uses the recursive least square (RLS) technique and an improved predictor algorithm is proposed to compensate for the channel correlation. The result shows that the performance of improved predictivepower control proposed in this paper evaluated in terms of bit error rate (BER) as a function of bit energy-tointerference power density ratio Eb/Io improved significantly from that of the conventional predictor."

"Dengan diterapkannya jaringan listrik konvensional pada sistem kelistrikan Indonesia, pemenuhan kebutuhan listrik yang meningkat pada waktu beban puncak menyebabkan tingginya biaya operasional penyediaan listrik pada saat itu. Hal ini dapat diantisipasi dengan melibatkan konsumen untuk ikut berperan aktif menghasilkan energi listrik bersama dengan Perusahaan Listrik Negara (PT. PLN). Virtual Power Plant dapat menjadi pilihan dalam mengendalikan berbagai jenis pembangkit dan terintegrasi untuk memenuhi kebutuhan listrik, termasuk mengendalikan energi listrik yang berasal dari rumah pelanggan. Oleh karena itu, diperlukan perancangan dua model diantranya Master Controller Unit dan Slave Controller Unit dalam sistem Centralized Virtual Power Plant yang dapat mengintegrasikan beberapa pembangkit, dan mendukung PLN dalam menghadapi kebutuhan energi listrik pada waktu beban puncak. Virtual Power Plant memudahkan pengguna untuk melakukan monitoring sistem pembangkit listrik dan melakukan transaksi energi listrik dengan PLN.

By implementing conventional power grids in Indonesian electrical system, fulfilling the increase of power demand during peak causes a high operational cost for electrical supply at that time. It can be anticipated by involving the consumers to actively contribute producing energy with State Electricity Company (PLN). Virtual Power Plants would be an option in controlling various types of power plants and be integrated in order to suffice the electricity demand, including controlling electrical energy originating from customers' houses. Therefore, it is need to design two architectural models as a Master Controller Unit and a Slave Controller Unit in a Centralized Virtual Power Plant System that can integrate several power plants, and support PLN when facing the electrical energy demand at peak load times. The Virtual Power Plant makes it easy for users to monitor power generation systems and conduct electrical energy transactions with PLN."

"Kebutuhan energi listrik dari tahun ke tahun semakin meningkat. Peningkatan ini sejalan dengan meningkatnya laju pertumbuhan ekonomi, laju pertumbuhan penduduk, dan pesatnya perkembangan di sektor industri. Adapun pembangkit tenaga listrik di Indonesia dapat dikelompokkan berdasarkan kepentingannya, yaitu untuk kepentingan umum dan untuk kepentingan sendiri. Pembangkit tenaga listrik untuk kepentingan umum sebagian besar dipasok oleh PT PLN (Persero) dan sebagian lagi dipasok oleh perusahaan tenaga listrik swasta, dalam istilah umum disebut IPP (Independent Power Producer), serta koperasi. Untuk memenuhi kebutuhan para pelaku indutri diatas, maka penulis mencoba mengaplikasikan keinginin para pelaku indutri melalui Skripsi ini. Adapun pada skripsi ini menjelaskan tentang penggunaan Sistem automasi untuk monitoring daya listrik pada rumah cerdas yang dapat diakses secara online melalui Web Browser Internet Explorer. Dengan sistem online energy monitoring ini memungkinkan setiap rumah yang menggunakan solar system akan menjadi pemain aktif (active network) pasar yang dapat menentukan kapan saatnya jual / beli daya listrik dengan mengkontrol keseimbangan konsumsi dan daya yang dihasilkan sehingga alat ini menjadi alternatif aplikasi dalam memenuhi kebutuhan listrik, terutama kebutuhan listrik rumah tangga dimana tidak tergantung lagi pada jaringan listrik PLN.

Electricity needs from year to year increase. This increase is in line with the increasing pace of economic growth, population growth, and rapid development in the industrial sector. The power plant in Indonesia can be classified based on their interests, the public interest and for its own sake. Power generation for public largely supplied by PT PLN (Persero) and partly supplied by private power companies, in general terms called IPP (Independent Power Producer), as well as cooperatives.

To meet the needs of industry, the writer tries to apply the industry was through the desire of the perpetrators of this thesis. As in this thesis describes the use of automation system for monitoring electrical power in smart houses that can be accessed online via the Web browser Internet Explorer.

With online energy monitoring system allows each home with solar system will be active players (active network) market to determine when to buy / sell power to control the balance of power consumption and produced so that it becomes an alternative application in meeting the electricity needs , especially the electricity needs of households which do not depend anymore on the public electricity network."
