Abstract

The more commercial flights now, will be result more the number of aircraft operated and the competition to become the airline can keep operating even more difficult. Some airline companies can not compete with other companies, has gone out of business. This is one of them caused by the inaccuracy of an airline's decision in the selection of aircraft types. Type of aircraft used for flight routes should be tailored to the needs so that it can provide benefits to the company. The selection of planes is determined based on market analysis with indicators of the number of passengers, aircraft, engineering aspects of the commercial aspects or the operational costs of aircraft and competitor analysis. Aircraft direct operating costs are costs directly related to the operator of the aircraft in flight routes. Direct operating cost is very influential in the selection of aircraft types that will be used. On certain conditions the determination of the decision must be taken quickly, in which one of the conditions is the availability of relevant information. Information is the output system that can be utilized by the parties in need. Decision support system to determine the type of aircraft is a computer application that provides output in the form of aircraft operating cost information that can support managers in making decisions determining the effective fleet at the new flight routes.

Abstract

Presence is the most important activity, because it is related to productivity of employees and one part of human resources control indicator which aim to improve the potential of human resources itself. The function of presence programme is for knowing presence of employees by used android smartphone. The employees can entry their presence data by use the presence programme, they just need to touch the attendance button, check out from office button and also take a leave button, the result of entry data will be entered into database system in the form of an admin web. The function of the web is to determine the employees data entry and add employees data. The employees should used android smartphone with same wifi local area of the company that used also by the admin web because it became the benefits of local wifi. In this case we need three days for trial, with a wide range of trials from 10 users testing, 10 smartphones testing, access point testing, blackbox testing and also white box testing. The aim of user testing is done by employees with android smartphone is to know does the time result of entry data equal with the time result of admin in web. Smartphone trial by the employees is done by view notification alerts presence was accepted by the admin, the result show if the average is less than 20 seconds. Access point trial done by the admin, is to show the speed of access point received by androind smartphone is less than 10 seconds. Black box trial and white box trial done by admin, the flow of the web, and also the flow of android smartphone program get the 100%. The result of three days trial finds that everything in presence program is going well.

Abstract

One way to take advantage of current technological developments is to utilize the smartphone as a means of accessing the Internet network. Open Journal System Application (OJS) Application Design Concept (OJS) In Mobile / Android Covered For Readers and Author (OJS based on android) is where the application system will access the existing OJS database on the server then the data will be transferred into the application , So that OJS data on the server can be retrieved and can be entered into OJS Based Application android. Thus users / readers no longer need to access the browser, because in the Android-based OJS application will display the pdf-shaped article files.From the analysis of comparative function and viewing of OJS application that opened with browser, with OJS android based application, in essence has the same function that is displaying the work of ilmia from an institution from a researcher, but there are some deficiencies in OJS Application Based Android , Such as in the application can not display data that resides in OJS database as a whole.

Abstract

The increasing number o f passengers Trans Jogja bus stops can result in the existing capacity can not accommodate the number of passengers comfortably. Problems that often arise include delays resulting bus passenger waiting time is longer and there is a buildup of the number of passengers at stops. As a result of these problems, the capacity o f passenger stops can be full so that prospective passengers waiting outside the bus stop. Forecasting is one very important element in the decision. In this study using stationary and trend forecasting the data because the data are not significant changes between time and swell in certain periods and a normal in periods others. Time series methods for forecasting the number o f passengers on the Trans Jogja stop using exponential smoothing calculation and least square. From these calculations the value sought MAD (Mean Absolute Deviation) or least square error is exponential smoothing and forecasting results with small error. Forecasting will be better if it contains fewer possible errors.

Abstract

Lamp is a kind of electronic that created light. Light is obtained through the flow of electricity as a current to add a voltage. the die and the life of light are controled  by humans using switch. Applying the  Internet of Things, as known as IoT determined the life and the die of a lamp by determined by the active light censor. The die and the life of the lamp automatically depends on the light sensor by capturing the intensity of the light produced. The result of the function test found that the data in the form of lux value generated by the light sensor, the value is exposed on a website with the display of graphics and websites serve as a web service provides control values to determine the response lamp, if the value of lux above 30 percent then the lights off And vice versa if under 30 percent of the lamps are on, so that a small value will be sent to the lamp and the lamp will respond that the lights are off or on.
