PEMETAAN DAN LOKALISASI SECARA SIMULTAN ROBOT iSRo MENGGUNAKAN MULTI-SENSOR
No full textSLAM (Simultaneous Localization And Mapping) is a technique used by a mobile robot to build maps of the area being explored, where the area previously unknown forms of terrain. In SLAM, the robot will perform two tasks at once, which form the map and also able to determine the position of the robot in the map. In this final project, created a program visualization to describe the movement of a robot, either direction toward the robot, the distance the robot, the form of obstacles that have been detected by the robot. Package data transmitted by the robot contains data about the distance from obstacles ultrasonic sensors, direction toward robots that come from digital compass output CMPS03, and the distance the robot using data from the rotary encoder. Data packet will be sent to the software that was created by using serial communication continuously. Moreover, in this program, we also can know the position of the robot which is updated continuously. From the results of testing this final project, obtained data that the image distance between the process of updating the position-x with the-x-1 is still too far away or there is a gap so that the resulting picture is less subtle. In addition, the slip that occurred on the wheels also provide a level of reading error, because the slip will not be readable by the rotary sensor. Range compass sensor readings are still not detailed. Range of measurement will be changed every 100 course not every 10 thus affecting the level of subtlety of images produced when the mapping process. Keywords: SLAM, robot, ultrasonic sensors, digital compass, rotary encode

Visualisasi Kinerja Pengkodean Menggunakan Algoritma Viterbi
No full textDalam perkembangan teknologi informasi dan
telekomunikasi yang begitu pesat khususnya pada sistem
komunikasi, proses pertukaran data yang terbagi pada dua sisi
utama yaitu pada sisi pengirim dan pada sisi penerima, masing
masing memiliki mekanisme kerja tersendiri dan memiliki ruang
lingkup yang sangat luas. Sangat tidak mungkin untuk
mengetahui dan memahami seluruh mekanisme yang ada tanpa
mengetahui setidaknya salah satu bagian dari mekanisme
tersebut atau prinsip kerjanya, untuk itulah pada proyek akhir ini
dibuat suatu sistem perangkat lunak untuk sebuah visualisasi
kinerja pengkodean menggunakan algoritma viterbi.
Prinsip kerja dari algoritma viterbi adalah mengkodekan
kembali bit - bit data yang telah dikodekan oleh convolutional
code dengan prinsip maximum likelihood atau mencari
kemungkinan bit - bit yang paling mirip antara bit yang diterima
pada sisi decoder dengan kemungkinan bit - bit yang muncul
sesuai hasil proses pada convolutional code pada tiap - tiap
percabangan trellis.
Dengan mengetahui bagaimana kinerja algoritma viterbi
kita dapat mengetahui setidaknya satu mekanisme pembentuk
suatu sistem komunikasi yang komplek, sehingga dapat menjadi
media pembelajaran yang baik dalam sistem komunikasi.

Analisa Kinerja Implementasi Wireless Distribution System Pada Perangkat Access Point 802.11 G Menggunakan OpenWRT
No full textWireless network is one of the best alternative for building a practical computer network. In some public area such as parks and cafes also office buildings have now largely been equipped with hot spot facility so that the visitors can enjoy a wireless Internet service. In addition, several agencies and offices have been using wireless network to support the existing cable network. However, the implementation of wireless nework still rely on a cable network that became the backbone of the access points so that connected clients (laptops, PCs, etc.) can access the Internet. This wiring problem would be a significant constraint on the places that are difficult to reach. The Solution of this problem is to implement the Wireless Distribution System (WDS) on access point device. WDS is a system that develop a wireless Internet network without using of network cable as a backbone for the access point, but taking the advantage of the wireless line from the access point. In this final project, the implementation of WDS methods are analyzed to determine the impact of its application to the quality and channel capacity of wireless networks. From the analysis and observations it is known that the implementation of the WDS can reduce channel capacity up to 33% of capacity without the application of WDS Keyword : Wireless Network, Wireless Distribution System (WDS), Access Point, openWRT
Analisa Sinyal Suara Pada Layanan IVR dan Predictive Dialer Berbasis CTI
No full textThe system used telemarketing are now sufficiently developed, where telemarketing is a service of selling goods or services via long distance. The majority of companies engaged in sales or services using this system, one development of the current telemarketing system is a network of information using IVR and Predictive Dialer systems. In this final project be carried on Voice Signal Analysis IVR service and Predictive Dialer based CTI. This analysis was conducted to determine the software and the best recording format, for further implemented on the IVR and Predictive Dialer systems. In the IVR system using the best software and the Predictive Dialer using the best recording format. The analysis process was carried out subjectively by Mean Opinion Score (MOS) and objectively by Signal to Noise Ratio (SNR) and Power Spectral Dencity (PSD). The result of this final project is the best kind of softwere implemented on the IVR system that is using wavesurver with survey results of 3.61 and the best recording format uses ADPCM 8KHz which are implemented on systems with Predictive Dialer survey results by 3.55 and SNR of 1.5780 dB Keywords: Subjective and objective analysis, IVR system, a Predictive Diale

PENGEMBANGAN SISTEM MONITORING TETESAN INFUS PADA RUANG PERAWATAN RUMAH SAKIT
No full textSystem of equipment for patient care at hospital in Indonesia is very less and also very dependent on the supply of equipment from abroad that cost is relatively expensive. On the other hand, the equipment is simple to use and in accordance with what they want the doctors and nurses or in the case of equipment that could quickly provide an information on the patient's condition, is still not optimal. Therefore, this final project aims to create monitoring tools that quickly provide information, easy to use and safe in terms of subject and object user. These systems monitor and control the drip rate in accordance with setting the upper and lower limit of the user. The system also sends data via serial communication on a PC, ie the number of drops per minute infusion / rate infusion. The droplets control is feedback from the input of setting the upper limit and lower limit which then will be maintained by a motor that has a drip hose clamp system. The design consists of microcontroller hardware atmega16, the drip of LED sensors and photo diodes, the series of LCDs, motor control and design software that is developing the algorithm, motor control, serial communication to interface on a PC using Visual Basic 6.0 programming language
