Disaster Recovery using Oracle Data Guard
No full textThe needs of the IT system is now become much higher, especially in terms of reliability and availability to support corporate's business continuity. It is important for companies to implement the concept of High Availability (HA) in order to protect the data which is the most important asset of the company. The purpose of this final project is to build disaster-recovery system that is easy to use, inexpensive, comprehensive, effective, efficient, reliable, and ensure the availability of data. The results of this project is a Data Guard system that can be implemented in enterprises, educational institutions, or other institution that use Oracle Database, to protect enterprise�s data from damage, disaster, failure, error, and routine maintenance that causes downtime. The system is expected to guarantee the availability of data for 24 hours per day, 7 days per week. In this system there are two kinds of database, the main database (primary database) and one or more database backup (standby database) which will be used if downtime occurred in the primary database
A NEW APPROACH TO ANALYSIS INVERTER OUTPUT CURRENT RIPPLE
No full textA new approach to analysis output current ripple from inverters is proposed. Current ripple has been analyzed by many different approach, such as time domain analysis, frequency domain analysis, and numerical method using digital simulation. Each of those method provides advantages and disadvantages itself. In this paper, frequency domain analysis is used. This method is based on the Fourier principle applied for inverter output waveform. The analysis is done by deriving the phase-to-phase mean square value of inverter’s load. Type of inverters will be analyzed in this research are three-phase inverter and six-phase inverter with dual wound stator induction motor. A technique to control the switching of these inverter is Pulse Width Modulation (PWM). Simulation also provided to verify the analytical result
ANALISA UNJUK KERJA AUDIO DAN VIDEO STREAMING PADA JARINGAN MPLS VPN BERBASIS IPSec
No full textSaat ini makin banyak masyarakat di Indonesia yang menggunakan aplikasi audio dan video streaming dalam kehidupan sehari-harinya. Dengan adanya videostreaming bisa digunakan untuk berbagai kegiatan seperti pendidikan jarak jauh ataupun sebagai sarana monitoring. Pada jaringan publik mempunyai kelemahan yaitu kurangnya keamanan komunikasinya, untuk mengatasi hal itu maka digunakanlah teknologi VPN (Virtual Private Network) pada jaringan tersebut. VPN memungkinkan terbentuknya sebuah jaringan data privat pada jaringan publik dengan menerapkan autentikasi dan enkripsi sehingga akses terhadap jaringan tersebut hanya dapat dilakukan oleh pihak-pihak tertentu. Pada paper ini menganalisa Qos dari jaringan MPLS VPN, meliputi parameter Qos yaitu delay, jitter, packet loss dan troughput. Dengan analisa ini diharapkan para pengguna teknologi audio dan video streaming mengetahui sejauh mana performansi dari aplikasi tersebut melalui jaringan MPLS VPN
RANCANG BANGUN MODUL PRAKTIKUM ELEKTRONIKA DAYA (BUCK CONVERTER - BOOST CONVERTER)
No full textElectronic switch-mode DC to DC converters or also known as DC Chopper is mainly used to provide the varies DC output voltage magnitude according to demand of the load. Power input from DC-DC process is derived from the DC power source which typically has a fixed input voltage. Basically, to produce a DC output voltage which achieved, able to do by setting the length of linkage time between the output and input on the same circuit. Components used to perform a liaison function none other is the switches (solid state electronic switches) such as thyristor, MOSFET, IGBT, GTO. Generally there are two functions of DC Chopper operation that is reducee voltage (Boost Converter) from 39 Volt to 15 Volt , and increase voltage (Buck- Converter) 10 Volt to 25 Volt. In this last project we used a PI controller to obtain good output (constant) of a series of DC - DC converter. But, there are still happen any fault om method deciding parameters of KP and KI. So, causing deformity as 6.4% on buck converter�s output within 15 Volt as setpoint, and 28% on boost converter within 25 as setpoint at maximum load.

SISTEM EMERGENCY DAN EVAKUASI BENCANA GUNUNG MELETUS-STUDI KASUS : GUNUNG API KELUD (SUB JUDUL : SMS GATEWAY)
No full textThe importance of information relating to the condition of Kelud Volcano very hard to identify. By using SMS Gateway-based Information System, the data processed by the system will be faster in terms of dissemination information to the public. This system will provide information about early warning systems and emergency evacuation systems. There are several stages it takes to manufacture the systems in digitasi process, design and create database, and perform the determination of early warning and evacuation systems and visualized. Because the information system is SMS (Short Message Service)-based, then use the appropriate technology that is python programming as system builder, gammu as sms engine and PostgreSQL as data storage. By using SMS Gateway-based Information System, data which are processed by the system will be faster in terms of dissemination information to the public. This system will provide information to the user who has the registration form of the status of emergency, disaster the actions to be performed, as well as providing information in the form of medicines, transportation, and other supplies through interactive sms
Real-Time WEB Base Laboratory Untuk Pembelajaran Jarak Jauh
No full textThe rapid science today require that every individual can compete and apply science knowledge to facilitate and expedite a settlement of the problem. With that reason, built a Web-based Real-time Laboratory for Remote Learning history. This web is built on six practical modules, namely Basic Logic Gate, Basic Series, Simplification of Basic Logic, Half Adder, concatenation Multilevel NAND and XOR circuits. This web was built using PHP, AJAX, MySQL database and displays using Dreamweaver CS3. With the construction of this website is expected to assist and facilitate the teaching-learning process, especially on Digital Elektonika practicum. This web is built on two sides, which acts as the client side and server-side students who act as administrators. Based on the results that have been done there are factors in the data transmission delay, delay is generated at each laboratory ranged from 1 ms to 3 ms on local network PENS, while using a wired LAN (pear to pear) delay value ranging from 1 ms to 5 ms depending on tissuefactor

Penerapan Algoritma Maze Mapping Untuk Menyelesaikan Maze pada Line Tracer
No full textABSTRACT Maze was a complex road network. In the robotics there were two types of maze that commonly used, namely the wall maze and line maze. Wall maze was generally known as the labyrinth, namely a road network that formed over the halls with the walls without a roof. In the line maze, a road network was formed by using the line. If the line was coloured white then the background was coloured black or vice versa. Problems that arose in the line maze was a way to get the shortest path from the line maze. In this final project, the problems in the line maze solved by maze mapping algorithm. This algorithm consists of two modes, namely search mode and return mode. In search mode, the robot traveled from the start position to finish with a rule that will put the robot to turn left when found intersection. Unique codes was generated when robot met with the intersection. In the return mode, the robot had been running from start to finish with the shortest way. The shortest path was obtained from a unique code that had been converted. Based on the experimental conversion program that had been done, it needed a powerful formulation to obtain the desired results. In testing the entire system, obtained an error of 10% from 10 attempts in a row. This error caused the battery condition was weakening. Keyword : robot, maze, mapping, PID, line senso
