Abstract

Distributed system is a computer networking technology which can be hardware or software. In hardware distributed system by a collection of computers that are heterogeneous, being in the software system is distributed in the form of software that connects two applications in the form of client and server side. TSC method is a method that already existed before, which can be used increase the ranking o f a blog. Implementation distributed system for TSC using landing page as the intermediary. Landing page serves as a liaison between web applications or blogs are listed as a member to raise the ranking of a database on the application server side. When someone does click on landing page seoindonesia, will open a blog or other web members. Landing page so it can be used as a way to count the number of visitors to a blog or website, which in turn can increase the number o f page visits and 1 with 1 clickbutton seoindonesia for test in histats.com.

Abstract

Many colleges already apply web based academic information system use internet connection, so it is need a system security to protect from attacks such as SQL Injection and Brute Force. Honeypot is a system security which devide two system that are original and fake system. Original system used by user to access academic information system that source from correct database. While fake system used to separate hacker and user. Hackers who try to enter with SQL Injection is send to fake system directly which has wrong data. This fake system seems correct and all action that was happened in will be noted on log history. When hacker try some password ese Brute Force, system will reset user password automatically. This system already test with 79 times SQL Injection and 29 times Brute Force attack. All attacks can handle nicely with honeypot algorithm.

Abstract

Lately, PLN as the state electricity company that supplmost of the electricity needs in Indonesia is being hit by a "trial" which is in a row with the burning of several Interbus Transformers (IBT) in several regions. This can be caused by the rupture of the bushing so that it triggers a short circuit and results in the burning of the transformer. However, so far the investigation of other causes has been minimal as well as the effect of the load which is primarily a nonlinear load. Electricity is a device / device that can function if it is electrified. The device / tool is used to convert electrical energy into other energy such as motion, heat, light and so on. Electricity load consists of linear load and non linear load. changes in the use of linear loads to non-linear loads, among others, from incandescent lamps to TL lamps, and many non-linear loads that are widely used such as the use of induction motors (motors used in water pumps, refrigerators, air conditioners, etc.), rectifiers, static power converter (rectifiers and or inverters), electronic ballasts cause harmonics. Harmonics are sinusoidal waves with frequencies which are round multiples of the fundamental frequency. Harmonics can affect the work function of the transformer, which causes more heating to the iron core, which causes an increase in loss. In this study, the losses will be tested if the load is linear and also if it is loaded with non-linear loads. The results showed that for small loads, the response of the two loads showed almost the same current. While for moderate loads there is a difference that has not been so large, and for large loads large currents indicated there are large differences. So that the copper losses and iron losses are greater when the load is large. Given copper losses there is a current flowing in the transformer winding and the presence of resistance in the winding (I2R1 + I2R2). so that the increase in load current will increase copper losses. So thereby increasing copper losses causes a decrease in transformer efficiency.

Abstract

The library is a place that is used as a study and reading room, so that a comfortable place is needed from disturbances in the library building. Based on the decision of the Minister of Environment in 1996, the standard noise for library environments ranged from 45 to 55 dB. but in fact there is often a commotion caused by visitors. in this study a noise level detection system was created where the noise detection system is expected to be used as a media for comfort control in the library room. The noise level detector uses a sound sensor that is connected to Arduino.The system will be equipped with a warning system in the form of Buzzer and Warning Text sounds that will be displayed on the P10 LED Panel and equipped with Internet of Things technology that allows the supervisor or guard of the library to monitor the noise of the library room real time via Web Server. The test results show that this tool can detect noise levels in the range of at least 41 dB and a maximum of 69 dB with a deviation of 0.6 and an average error of 1.0%. the average sound intensity measured in the library room is 56.24 dB. The average percentage of the success of the system against Buzzer and Warning text warnings is equal to 97.3% and the average percentage of the success of sending data to the web server in the noise level detector is 95%
