Abstract

Wireless transmission system is hampered by a condition that causes multipath channel fading at the receiver. It required transmission technologies that are resistant to multipath channel conditions. One is multiple access technology combination of OFDM and CDMA. To further increase the interference immunity of signal channel is carried out in combination with the MIMO antenna diversity technology.  This final project is to make simulation of multiple access technologies CDMA-OFDM combined with MIMO. The parameters varied are the number of the receiving antenna and the speed of the user. Channel used is the Rayleigh channel and Additive White Gaussian Noise (AWGN). The performance of the system can be measured Bit Error Rate (BER) compared to the value of Eb / No. Performance of 2x5 MIMO system with the speed of the user 5 km/h produces Eb/No 3 dB lower than 2x3 MIMO and 1,5 dB lower than 2x4 MIMO to achieve the target BER 10-3. Performance of 2x5 MIMO system with the speed of the user 40 km/h produces Eb / No 4 dB lower than 2x3 MIMO and 1 dB lower than 2x4 MIMO to achieve the target BER 10-3. At speeds of 80 km /h, the performance of MIMO  CDMA -OFDM system worst found on 2x3 MIMO scheme, the target BER 10-3 can not be fulfilled on the value of Eb/No = 30. 2x4 and 2x5 schemes provide better performance with a value of Eb/No of 8 dB and 4 dB to achieve the target BER.The increase in user speed degrade the performance of MIMO CDMA -OFDM system. With 2x5 MIMO scheme on the user speed 5 km / h, the target BER 10-3 is reached on the value of Eb/No of about 1 dB. While at the speed of 40 km / h and 80 km/h achieved at Eb/No value of about 2 dB and 4 dB. Keyword :   CDMA, OFDM, MIMO, Rayleigh, AWGN

Abstract

Fasilitas Pengolahan Air terpadu (WTIP) merupakan fasilitas penting dalam industri minyak bagian hulu. Dalam fasilitas ini digunakan beberapa motor induksi yang berfungsi untuk menggerakkan pompa, mengaduk isi tangki dan fungsi penting lainya. Sumber kelistrikan diperoleh dari Generator-set berbahan bakar diesel dan lepas dari sumber PLN, hal ini dikarenakan letak plant yang tidak memungkinkan untuk memasang jaringan ke PLN. Dalam perancangan sistem kelistrikan harus dibuat suatu skenario terburuk yang mungkin terjadi. Skenario terburuk yang mungkin terjadi adalah starting motor terbesar saat kondisi sistem dalam keadaan bekerja. Perhitungan kapasitas daya pembangkit yang harus disediakan harus memperhatikan skenario terburuk tersebut. Setelah dilakukan perhitungan secara manual maka system yang sudah dibuat disimulasikan menggunakan software ETAP versi 6.0 untuk memastikan system tersebut dapat bekerja secara optimal atau tidak. Dengan adanya hasil simulasi tersebut diharapkan sistem kelistrikan fasilitas pengolahan air terpadu dapat bekerja sesuai dengan yang diharapkan. Selain itu juga diharapkan dapat membuat perancangan sistem menjadi lebih efektif dan efisien. Keyword :   Water Treatment and Injection Plant (WTIP), ETAP, Worst scenario.

Abstract

Currently, determining the exact position and orientation in a technical system has an important role, especially in terms of control on a navigation system. One of the instruments used in navigation systems is the Inertial Measurement Unit (IMU). The IMU consists of a combination of the acceleration sensor (accelerometer) and the angular sensor (gyroscope) to track the whereabouts and movement of an object. Accelerometer sensor is one that has undergone a lot of progress and applied to measure the slope, vibration, acceleration, and position. Accelerometer can also be applied to the measurement of earthquake activity and electronic equipment, such as 3-dimensional game, computer mouse, and telephone. For further applications, sensors are widely used for the purposes of navigate in relation to the position of objects. This final project perform design and manufacture of instrumentation accelerometer as one component of IMU to detect the position / distance with 3 degrees of freedom. Data obtained from the position of the double integral of the accelerometer output in the form of acceleration. Instrumentation system consists of an accelerometer sensor, signal conditioning, microcontroller ATmega 32 as the main processing unit, and computers that will process data input and display output data using Visual C#, while the g-select function is used to determine which mode to use the accelerometer to minimize error in the measurement. Keyword :   Accelerometer, Microcontroller ATmega 32, Double Integral, Position

Abstract

Nowadays, the vehicle’s robbing or the usage of not allowed route is often happen. Therefore, vehicle tracking system is needed to reduce this risk. Vehicle tracking system is a system’s combination  that installed in the vehicle so that can be tracked by the owner or the third part. Modern vehicle tracking system usually use GPS to determine vehicle’s location. This system also usually have communication component such as cellular or satellite to send vehicle’s position to user in another place. In this Final Project, the vehicle tracking tool based on GPS via cellular  will be created. This tool is a part of vehicle tracking system. This tool will respond a command which is sent by tracker via SMS. The device contains of three parts. There are microcontroller as a control part, GPS which provide positioning information, and GSM modem which is used to send or receive message. All of these parts will cooperate to process all of the messages sent by tracker. Then server will get information about position in form of longitude, latitude, date and time. This device will be tested in case of receiving’s delay at tracker side, timer’s precision, location’s precision which is showed by GPS, vehicle tracking. Based on testing, there are varying receiving delay at traker side. Timer has  ran well so that getting data appropriate to the interval which is asked. Position which is showed by GPS is not precision in fact. However, the tracking can be done and similar with the fact in the field.Keyword :   GPS, vehicle tracking system, cellular communication
