Abstract

Penelitian ini bertujuan untuk mengetahui kinerja penyearah terkendali satu phasa dengan melakukan perbandingan penggunaan filter pasif dan filter aktif yang dibebani tahanan (resistor) sebesar 20 Ohm. Nilai Total Distorsi Harmonik (THD) dan faktor kerja (PF yang menunjukkan kinerja penyearah diukur secara langsung di dalam simulasi rangkaian dengan menggunakan PSPICE versi 7.1 Hasil penelitian menunjukkan bahwa harmonisa atau THD yang timbul pada penyearah terkendali satu phasa dengan menggunakan filter pasif pada sudut penyalaan 100 – 600 adalah 1,914% -2,591%, sedangkan pada filter aktif sebesar 0,448% - 0,769. Dari sisi keluaran penyearah diperoleh riak tegangan sebesar 17,13% – 52,52% pada filter pasif, sedangkan filter aktif sebesar 21,53% - 30,92%. Berdasarkan riak tegangan yang diperoleh dari kedua filter ini, maka diperoleh faktor daya antara 0,27 - 0,52 (leading) dan efisiensi antara 78,38%-97,15% pada filter pasif sedangkan pada filter aktif diperoleh faktor daya sebesar 0,76 – 0,9 (lagging) dan efisiensi 91,27%-95,57. Dari hasil analisis dari kedua filter tersebut menunjukkan bahwa kinerja filter aktif lebih baik dibanding dengan filter pasif.

Abstract

This research aims to control the DC motor rotation using the control system using PID (Proportional Integral Derivative). To see the performance of PID controller, it will be compared to a DC motor using PI controller (Proportional Integral)). From the results of experiments that have been done indicate that the DC motor using PID controller when starting without load takes about 0.066 seconds. While the DC motor using PI controller takes about 2.345 seconds. At the time of granting the load, the DC motor using PID controller requires recovery time to reach the setpoint was 0.034 seconds. While for DC motor using PI controller requires recovery time to reach the setpoint is 0.411 seconds.

Abstract

The advance of computer security technology has led to the invention of many cryptography algorithms. Visual Cryptography is a cryptography technique that needs no cryptographic computation in decoding. To encode a secret image, the image is encrypted to several transparent shares. In order to retrieve the secret image shares are stacked on top of each other. This paper describes a technical implementation of this algorithm on a square black and white image for VC2,2 Scheme and VC3,3 Scheme. The result shows that the model works well with an image that contains text.

Abstract

Education world of Indonesia experiences development along with integration between conventional study and e-learning bases method on web. Some universities in Indonesia offers service e-learning to base on web with a few content interaktif which can be exploited for expansion of quality of education. Content e-learning for example upload/download matter bases on document, chatting, live video streaming, and video conference. University of Nusa Cendana (Undana) also does system development of study of e-learning bases on web. Now content which on the market still limited to upload and download document. Video service conference have been implementation, but communications only support communications point-to-point and has not integrated with website elearning. Based on the limitation hence writer wish to develop the system becomes communications multipoint to base on web and can be integrated with website e-learning undana.

Abstract

Global of System for Mobile Communication (GSM) is a cellular communications technology having the character of digital. Technology GSM many applied at peripatetic communications, especially handphone. This technology exploits microwave and delivery of signal divided based on time, so that information signal sent will come up with purpose. GSM is made by global standard for cellular communications at the same time as cellular technology which at most applied people in the worldIn this study will make a simulation of dual-band GSM 900 and GSM 1800, system 1 traffic will overflow to system 2 if the server system 1 is busy. Traffic on the system 2 will be blocked if the server system 2 is busy. Simulations are made with varying number of server, number of events, average arrival rate, and service rate to see its effect on blocking dual band system. The simulation results show that increasing the number of servers (N) and the service rate (μ) will lower the value of blocking. While increasing the number of events (LE) and the average arrival rate (λ) will increase the value of blocking.

Abstract

Generally installation of lighting applies manual switches to turn-on and turn-off the light electricity through connection cable. This system besides less efficiently also able to generate voltage shoot or losses energy if lamp distance with rather far linkage switches. More than anything else if there are any diffuse joint, hence can result heating generating over current, even can cause burning.This paper aim to make a controller device by using infrared. Remote infrared control can replace function of switches that is commonly use at installation of lighting without using connection cable. Planning of this device done by using data signal 660 Hz while signal carrier applies frequency 40 Khz. Result of gauging of oscilloscope at data frequency is obtained by gauging of 666,67 Hz or there is difference around 1.01 %. Then at generator carrier is obtained by gauging of frequency around 41.67 Khz or there is difference around 4.18 %. Result of assaying of device indicates that remote control has functioned carefully as according to what planned, that is can turn-on and tirn-off lighting without using switches. Lamp controller can be put accross comes up with distance 9 meter with acceptance angle 0 - 20 degrees.

Abstract

Diesel Power Plant (Diesel) is one of the plants that use fuel oil to generate electricity. Because of the high price of fuel, it is necessary to schedule the operation of the generating units, so that in addition of generating electrical power quality in accordance with the needs also fuel consumption can be optimized. Optimal scheduling of generating units can be done by selecting a combination of operating generating units which produce a certain power and the least fuel consumption as a first priority to operate.This study aims to examine the optimization of fuel consumption in Diesel Kefamenanu. By calculating the Incremental Rate of generating units that exist by using algebraic methods, it can show the optimal combination of operating generating units and how much the fuel consumption of the combined operation of the plant units.
