The ability to perform vehicle tracking is very useful in daily life - today, such as security on personal vehicles, public transportation systems, fleet management and other mass transit. In this study, we designed an application of Geographic Information Systems (GIS) that will be applied to public transport services. This system provides real-time position tracking of each vehicle (taxi) and capable of providing a taxi with the best category for passengers using Dijkstra's algorithm. This system can be helpful, especially for passengers who are often too long waiting for a taxi that had been booked and also helps the driver to save fuel consumption because the taxi drivers do not have to drive across town to get the passengers and are just waiting for confirmation sent by this system.

High Altitude Platform Station (HAPS) is one of a new infrastructure in telecommunication, which is like airship or aircraft that is placed on the stratosphere. The distance of platform is about 17-22 km from the earth's surface. However, in its application HAPS that placed on the stratosphere layer of air is affected by the wind gusting. Position HAPS can change from the normal state that is called Platform Displacement. In this research discuss about platform displacement impact that experienced by the mobile station (MS) during the handover (HO) process. User is mobile WiMAX user who is using VoIP communications services. Performance of the system is calculated by some parameters value, there are throughput, data dropped, and HO (handover) delay. System will be simulated using simulator OPNET Modeler 14.5. In the simulation results can be seen the influence of platform displacement and speed of the user. When platform moves to the higher altitude will increase the area of cells coverage so that each cell can interfere its neighbor cells, especially in the transition region where MS do HO process. This condition can disturb HO process and increase data dropped during HO process.

Current fan is not able to display room temperature and humidity. It also cannot run automatically on a specified time or room temperature. Therefore it should consider a system that can overcome these weaknesses. This research will make a room temperature control system that can detect temperature and humidity, and displays the results to the application. Systems made useful to control the fan so that the room temperature is still cool. The system will interact with the user through the application, both for switching on and off the fan directly or automatically based on temperature and time. This research uses the C# programming language in the creation of applications and C for coding of microcontroller. The methodology used is prototyping. Testing conducted concluded that the application can display the values of temperature and humidity, a function to turn on and turn off the fan directly or based on temperature and time can run well.

In this paper, a beam reconfiguration of antenna array composed of four elements microstrip square patch antenna is proposed by use of capacitor chips. The array of antenna which is deployed on an FR4 Epoxy dielectric substrate is intended to operate at center frequency 2.4GHz for wireless communication application. The four patch antennas are arranged in a horizontal array employing microstrip line as its feeding network. There are two configurations of capacitor chips incorporated into the antenna array, the first with capacitances of 1pF, 10pF, 10pF, 1pF and the second with capacitances of 0.5pF, 1.5pF, 1.5pF, 0.5pF for each feeding line connected the antenna patch. The beam reconfiguration is shown by characterizing the antenna array and comparing the result for an array without and with capacitor chips. From the measured results, it shows that the magnitude and phase of reflection coefficient as well as the radiation pattern of proposed antenna array are influenced by the presence of capacitor chips. The first configuration of capacitor chips changes the reflection coefficient at frequency of 2.46GHz from -17.18dB to -9.68dB, the phase shift into 81.48°, and a slight deflecting beam maximum angle of 10°. Whilst from the second configuration, the result shows the reflection coefficient of -7.46dB at frequency of 2.48GHz, shift of antenna phase into 73.89°, and deflection of beam angle up to 20°.

In this paper, a broadband user demand forecasting in Indonesia based on Fourier analysis is presented. In this approach, the historical data of broadband user demand is considered as time-series data. To obtain trend of the time-series data, polynomial expression is incorporated in the Fourier series representation instead of constant. The presented forecasting model is then confirmed its validity by using hypotethical daily price fluctuation data. It can be shown that the presented forecasting model gives good agreement between forecasted data and actual data. The same forecasting model then is applied to forecast broadband user demand in Indonesia. Several cases of fixed and mobile broadband are presented. It can be shown that the forecasting model based on Fourier analysis gives good result with the error of the estimated value is less than 10%.

The design of digital TV DVB-T2 transmitter infrastructure is done by multiplexing broadcasters in Indonesia, at this time there are many who use the concept of analog TV transmitter infrastructure planning, which in its design avoid two transmitters with the same frequency in the service area as it will cause interference to received signal by the public. With Digital TV DVB-T2 technology allows to design 2 transmitter in the area of service without occurring interference to each other (SFN), it is due to the feature of the guard interval that tolerate varying propagation delay between 2 transmitter antenna when the signal received by public. In this paper carried out the design of a digital transmitter infrastructure that utilizes new features DVB-T2 technology to provide Jabodebatek area TV digital broadcasting. To utilize the DVB-T2 features, three design options was proposed Option I use one transmitter, option II use two transmitters and option III use the four transmitters. All option was designed in order to meet the minimum operational parameters that have been set by the government. After designing all options is done, then compared the results technically and economically. Technical analysis is done by comparing the capacity and coverage of the population of each design, economic analysis is done by comparing the analysis of business each design using a calculation of payback period, NPV (Net Present Value) and IRR (Internal Rate of Return). It was concluded from the results that the design that use 4 transmitters is the most optimal to be implemented in the Jabodebatek area. The optimum design obtained 27.87 Mbps in capacity, 99.9% in population coverage (29,408,063 inhabitants) and IRR 9.64%.

The development of technology has an impact for the transportation sector, one of them is about parking the vehicle. Parking is a state where a vehicle is not moving for a short time because the driver is going for somewhere else. To find an empty parking spot, a driver must look up for a parking lot that has been allowed for parking, it is quite difficult to find a parking spot because the space available for parking is very limited and the amount of vehicles that need parking is very high. It needs a relatively long time for a driver to get a parking spot and can cause a traffic jam in the parking lot because many drivers are trying to find an empty spot for their vehicles. This is the reason why the author develops an application for parking lot using Android Smartphone. This paper uses Rational Unified Process Methodology and the tool that used for this paper is Photoshop CS5, Adobe Dreamweaver, MySQL, and using Unified Modeling Language tools. The programming language that used for this paper is PHP (Hypertext Preprocessor).

This paper presents an impedance matching circuit for monopole antenna in the frequency range 30-88MHz which is integrated by microcontroller with tuning algorithm as an automation component. An impedance matching type L is used for the circuit, while for the realization some trimmer capacitors and SMD inductors are employed. To get an input voltage for the microcontroller, some supporting circuits are designed including VSWR meter, comparator and amplifier with 2 levels. It shows that the circuit is successfully tested by replacing values of load impedance with ZA = 75 + 14.6952j and ZB = 75 + 25.6224j, and tuning frequency values in frequency range of 41-45MHz. When impedance matching circuit is active, VSWR values for load impedance ZA = 75 + 14.6952j in the frequency 41MHz, 43MHz, and 45MHz are 1.34, 1.35 and 1.5, respectively and for load impedance ZB = 75 + 25.6224j are 1.37, 1.373 and 1.5.
