<![CDATA[Radio frequency identification (RFID) is a tool for identifying objects using radio waves. RFID reader consists of a reader and a tag as the object is read. This technology is efficiently used in the manual library UNTAD as library card for its use without having direct contact (Contacless). Results of identification RFID reader in the form of a unique series of numbers. RFID reader is connected directly to a PC via a USB cable (Universal Serial Bus), so that the identification appear on the LCD monitor screen. The identification result is managed by the application that is made from Visual Basic 6 with GUI (grapichal User Interface) that simple connected in Acess 2007 database so that the library data is stored properly. Microcontroller ATMega8535 serves as a voice recorder module controller ISD 1820 remind visitors to fill out the list of visitors of the PIR sensor detection results when there are visitors who come in and as recipients visitor data contained in the application is then displayed on the LCD 2x16. From the combination of these technologies can overcome UNTAD library system is still manual because it produces a rapid and accurate data.]]>

<![CDATA[Salah satu indikator dari keandalan sistem distribusi tenaga adalah ketahanan kelangsungan pasokan listrik kepada konsumen. Oleh karena itu, diperlukan suatu sistem yang mampu dalam melakukan tugas pengawasan dan pengendalian kinerja sistem distribusi tenaga secara real-time dan berbasis komputer. Sistem itu berarti kriteria yang disebutkan sebelumnya adalah sistem SCADA (Supervisory Control dan Data Acquisition). Sistem SCADA yang telah terintegrasi ke sistem distribusi listrik memiliki kemampuan untuk meminimalkan disturbanced yang memiliki implikasi pada indeks keandalan jaringan distribusi listrik. Beberapa parameter indeks keandalan jaringan distribusi listrik adalah nilai SAIDI (Sistem Average Interruption Duration Index), nilai SAIFI (Indeks Frekuensi Sistem rata Gangguan), dan nilai CAIDI (Pelanggan rata-Gangguan Duration Index). Yang lebih kecil dari indeks nilai, lebih dapat diandalkan dari kinerja sistem. Untuk memaksimalkan keandalan listrik jaringan distribusi listrik yang terintegrasi dengan sistem SCADA, infrastruktur pendukung sistem harus peduli. Ini berarti bahwa peralatan listrik di jaringan distribusi yang terintegrasi dengan sistem SCADA harus memiliki synchonization akurat, kemampuan untuk remote control, dan dapat dipantau dan contorlled secara real-time Kata kunci: SCADA, SAIDI, SAIFI, CAIDI and Index of Power System Distribution Reliabilty]]>

<![CDATA[Pengendali digital PID (Proportional Integral Differensial) adalah pengendali yang banyakdigunakan pada sistem pengendalian proses industri. Pengendali ini memiliki struktur yangsederhana tetapi memiliki aplikasi yang luas. Pengendali ini dapat diturunkan menjadipengendali PI (Proportional Integral) dan PD (Proportional Differensial). Suatu pengendali digitalmengukur variabel proses yang akan dikendalikan pada setiap selang waktu yang spesifik yangdisebut waktu sampling. Pada setiap sampling atau pada tiap pengukuran dari variabel proses,datanya adalah adalah data analog yang harus dikonversi ke dalam bentuk digital sebelumdiproses oleh kontroler. Kemudian pengendali mengolah tiap sampel dari variabel proses untukmenentukan besar error terhadap set-point, dan berdasarkan error inilah, pengendali digital PIDdengan menggunakan algoritma PID menghitung sinyal kendali yang harus diberikan ke proses.Tujuan penelitian ini adalah merancang pengendali steam turbin berbasis kendali PID denganmenggunakan perangkat lunak yang dibangun dengan menggunakan algoritma PID. Padaperancangan sistem kendali ini diharapkan dapat memberikan sistem pengaturan frekuensiterhadap gangguan perubahan beban yang dapat mengakibatkan kerusakan peralatan listrik,serta tidak meninggalkan kinerja dari kontroler PID dalam aspek tanggapan peralihan, kesalahankeadaaan tunak, dan kesalahan kuadratik yang diterapkan pada sistem pengendali steamturbin]]>

<![CDATA[AC Induction motors are sized for maximum load and are operated at a constant full speed, because they are supplied with power from AC lined at a fixed-sinusoidal voltage and fixed frequency. However, load of motor does not always same at many conditions but the input voltage and power of motor is fixed. Of course, it will influence the efficiency of the motor. One method to improve efficiency of the motor is varying the voltage as loaded its and called Motor Controlled. Motor Controlled is AC Drive that using SCR (Silicon Controlled Rectifier) as the output voltage controller by controlling the firing angle. By employing SCR Motor Controller that adjust the voltage of the motor offers advantageous to improve efficiency of motor and potential for significant energy savings.]]>

<![CDATA[Optimization problem is the demanding problem for optimum solutions. The optimum (best) solution is asolution with minimum values, or maximum among a set of possible alternative solutions. In electricaldistribution network, problem of demanding achievement of optimum condition of system operationalperformance is essential. One of the factors necessary to consider in the designing of the primary electricaldistribution network is cost. Cost is closely related to length of cable used. It highlights the importance ofcalculating the minimum length of cable required in a network. The cable should be not only with as minimalas possible in length, but also regulated for better arrangement.Actually, in regulating the cable installation, longer path is more frequently selected. One of the ways ofachieving optimization condition is to use algorithm to determine a minimum spanning tree of the primaryelectrical distribution network system. In this study, the algorithm used is Prim’s algorithm.The research was conducted by designing a graph model of primary electrical distribution network inappropriate with the data obtained. Based on the graph, each was weighted for distance or length of networkcable by using the ArcView GIS 3.3. The data were then calculated and simulated by using computer to gaina minimum spanning tree of the primary electrical distribution network using the Prim’s algorithm]]>
