Penentuan Kapasitas Arus Surja Alat Proteksi Petir (SPDs) Yang Dibutuhkan Sebuah Gedung Yang Tersambar Petir Secara Langsung
Get PDFIf lightning rod of building is directly struck by lightning, then lightning current will flow through lightning rod, down conductor and then through bonding bar. Lightning current will be distributed to lines that are connected with the bonding bar, among other things: grounding electrode, plumbing, power line, telephone line and other conductors are connected to the bonding bar in the building. Lightning current distribution on a building is different from other buildings, depending on the existing conductor lines in the building. Therefore, before installing SPDs at the lightning protection system on a building must first calculate the lightning current distribution in the building to determine the maximum current surja be borne by SPDs. In this study conducted determining the maximum lightning current capacity of the SPDs that required every conductor lines in the building by calculating the ligtning current distribution. Variables that cause changes on distribution lightning current was varied to obtain the maximum lightning current that bear by SPDs. The calculation is done by using EMTP program. The results showed that when the building directly struck by lightning, not all lightning current flow into the grounding but will be distributed to the existing conductor lines in the building. The results showed that out of five cases calculated, the largest lightning current flow into power lines are 7.29 kA and the largest lightning current through the telephone line is 50.9 kA. Key words: Lightning current, SPDs, EMT
SISTEM TELEMETRI Unmanned Aerial Vehicle (UAV) BERBASIS Inertial Measurement Unit (IMU)
Get PDFTelemetry is a process used to measure or record of a physical quantity in a location far away from thecentral processing of measurement results. Telemetry systems on unmanned aerial vehicles can provide information such as position, altitude, direction, and status in real time rides themselves during air vehicleis operated.The system consists of hardware and software. Hardware such as the IMU consisting of microcontrollers and sensors. For software consists of ground station systems that receive and process data from the IMU.On the software is equipped with aircraft instrumentation systems.On the test results, the system is able to provide information IMU slope rides, although there is still a noise at the output of each sensor. Instrumentation rides well it works exhibit a vehicle. Tracking can be performed by using a ground station

Get PDFProses Pengiriman Paket IP Menggunakan All Optical Label Swapping (AOLS)
Get PDFTransmission IP packet into WDM network will experience of encapsulation process at Data Link Layer with adding overhead to packet. IP packet through Gigabit Ethernet have more less overhead than ATM. The usage of All Optical Label Swapping (AOLS) technology for transmitting IP packet into WDM network with using label swapping will add optical label to packet. At AOLS, process routing decision is to be done with only processing the optic label. During that process data payload constantly within optic domain. Key word : ATM, Gigabit Ethernet, AOLS, optic label
Conveyor Simulation of ER Performer MK2 Robot
Get PDFRobot simulation softwares are usually required by designers or engineers to model a robotic work-cell, simulate its operation, and program the robot before operating it in its real situation. One of the most powerful CAD/CAM robot simulation softwares is CATIA, a product name developed by Dassault System. This software is well-recognized by several of its positive features in which two of them are wireframe modelling and collision detection. The development and operation of ER (Eshed Robotic) Performer MK2 robot modelling and simulation in this research is carried out using wireframe modelling capability of the CATIA software. This software is capable to create 3D objects in 3D space mode
Desain Dan Implementasi Wireless LAN Berdasarkan Perhitungan Link Budget Dan Throughput (Studi Kasus BBS UnilaNet Tiga Satu Mandiri Prima)
Get PDFWireless LAN (Local Area Network) or WLAN is an information technology (IT) which use radio frequency or infrared (IR) as a transmission media. WLAN technologies have a wide coverage area and large capacity. WLAN Implementation must follow the rule of design; one of this is link budget calculation. University of Lampung (Unila) in this matter represented by Bulletin Board Service University of Lampung (BBS UNILANET) is.developing a hotspot wireless network in Unila using WLAN technologies. BBS UNILANET working together with experts from PT. TigaSatuMandiri Prima, an IT company, to implement WLAN in Unila. From this cooperation, it became necessary to implement a wireless network connecting BBS UNILANET to PT. TigaSatu Mandiri Prima. The purpose of this experiment is to design and implement WLAN from BBS UNILANET to PT. TigaSatu Mandiri Prima and to get calculation result of link budget and throughput. The result of the experiment show WLAN design from BBS UNILANET to PT. TigaSatu Mandiri Prima designed with a qualified standard rule of WLAN, based on height (BBS 124 meter, PT. TSMP 107 meter) and between the two point is Line Of Sight (LOS) ranged at 7.18 Km. Implementation builded with a set of Senao and WLG-2450-24 Grid Antenna in each location and pointed at each other (point to point) resulted in signal quality of 100 percents and signal strength of 70 percents.
