Abstract

The development of mobile technologies very rapidly at this time, can be seen in all areas of human life. It triggers the level of usage of mobile equipment itself, this time in the form of a smartphone gadgets familiar to the adults and children. IQ tests that exist today are still many that are manual and less desirable, especially for the children. With combined by mobile technology and packed into a game, is expected to add to the child's interest and can be used as a means of learning. The test results of 30 respondents, the level of user satisfaction based GUI Display, User Friendly and Final Game IQ Method Using Binet-Simon-Based Mobile, obtained a percentage of 71.31% keselurahan assessment. Thus Game IQ can be said Good

Abstract

Student departure monitoring is an Android-based app used to monitor student departure to school. This system runs on parent smartphones so parents can see the existence of students and the app will give a message if the student out of the route path that has been set. Arduino used is arduino uno nano type. Arduino programmed using C language, to monitor the existence of students also required some components such as GSM Module and GPS Module. In testing the user application can monitor the existence of the students through the mobile phone that has been installed the application, before monitoring the departure of parents students are required to enter data coordinates home, coordinate data route and data coordinates of schools entered manually. To get the coordinate data the parent can take it through google Maps. To avoid failure in the use of remote control applications should use Android smartphone version 4.1 Jelly bean to version 6.0 Marshmallow. In the experiments this application can run smoothly with the Android version 4.1 to Android version 6.0 and the results of the questionnaire given to the 30 respondents with 9 questions 75.77% results obtained using Likert-scale calculations, which results obtained a good assessment interval.

Abstract

The limitations between the amount of bandwidth and users can make the internet slow. Observing the flow of data on the internet network is one way to identify the  bandwidth requirements which used on the STTA office network. This thesis analyzes the data traffic with sharing system model. The observed data is in the category of elastic flow rate, i.e: TCP (Transmission Control Protocol). The traffic data is converted to a measured data graph and then  analyzed  by  traffic  load,  throughput,  and  flow  of  loss  parameters.  The  highest observation value of traffic load is 0.37, Throughput of 9.3 Mbps (93%), and the flow of loss of 23%. From the results of the research, it can be concluded that in general internet network at STTA office is in good category.

Abstract

Rookieinside is a store that moves in the field convection. Rookieinside had a bad in the determination of goods production which must be manufactured for sale and sometimes experience of excess supply in stock goods in the warehouse. Rookieinside requires a tool aids that can help and to maximize their performance in forecasts of work that must be manufactured so that work was not pile up in the warehouse. This application is made by using this method Weight Moving Average and Smoothing Exponential. Result of this application information about the number of record amounts that might have happened in the same will come. This application is useful to take a decision in determines the amount of work that will be produced in next period.

Abstract

The earthquake that occurred around the world, generally always cause building damage and casualties. The number of fatalities occurred due to the lack of early notification and earthquakes happen very quickly. The software developed in this study can detect the strength of the earthquake. Magnitude detection software is designed to be equipped smartphone device accelerometer sensors and GPS. Smartphone users who apply this device will allow earthquake information (magnitude) faster than BMKG. The experimental results with comparison earthquakes that have occurred naturally suggest the software can be applied to well. Users of smartphones equipped with an accelerometer and GPS that applying this software can improve alertness when it will take place.

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.
