<![CDATA[Wireless communication is used in many sectors to support the need of communication, the example of wireless communication is applied in mission critical network. Wireless communication system that used in mission critical are Terrestrial Trunked Radio (TETRA) and Long Term Evolution (LTE). TETRA systems supports voice services while LTE supports voice and data services. Co-exsitence between LTE and TETRA in same frequency band is one of the optimilazition quality for mission critical network. For this final project analyses interference in co-exsitence between LTE and TETRA in frequency band 800 MHz. There are four scenarios using extended-hata model propagation in urban area. There are several parameters that reviewed, desired Received Signal Strength (dRSS), interfering Received Signal Strength (iRSS), Carrier to Interference ratio (C/I) and probability of interference. In all scenarios occur Co-Channel Interference (CCI) between LTE and TETRA in frequency band 800 MHz so the performance not optimal. The performance increased when add guard band variation. The variation that applied are 0,5 MHz, 0,75 MHz, 1 MHz. Based on the result of the simulation that have been done, proposed the used of guard band variation for elevate the performance.]]>

<![CDATA[Satellite technology is a telecommunications technology where the satellite is a communication device placed in space and requires the allocation of the frequency spectrum for telecommunications services. The most widely used frequencies for satellite communication are the C-Band frequency (4 GHz to 8 GHz) and the Ku-Band frequency (12 GHz to 18 GHz). Also, Ka-Band frequency (26,5 GHz to 40 GHz) is the center of attention in the telecommunications industry nowadays because it has a large enough bandwidth to accommodate more service capacity. In this article, a microstrip antenna with a rectangular patch of four elements (array 2x2) has been designed using line feed rationing techniques that work at a frequency of 29,25 GHz (Ka-Band) for satellite communication. An appropriate antenna dimension is required so that the antenna can work and has a good performance at the expected frequency. Simulation results show a return loss value of -43,052 dB, VSWR is worth 1,014 with a bandwidth of 2,728 GHz. In addition, the resulting gain value is 7,823 dB with directional radiation patterns and ellipse polarization.]]>

<![CDATA[This article discusses about device-to-device communication on 5G cellular networks using mmWave. Device-to-device communication will support 5G cellular technology, because it can be a solution to overcome the limitations of cellular coverage and service capacity. D2D can be used in a variety of applications. The main problem in D2D is that interference between signals in one cell will be very vulnerable to occur, so that effective resource management is needed. In addition, the use of D2D will also increase the complexity of a cellular system, in terms of resource management, interference, and also the routing required. Several studies have been carried out to create D2D communication that can be implemented effectively on 5G. One of them is research to perfect the load balancing scheme which is one of the functions obtained from D2D communication. Load balancing is the distribution of cellular traffic loads, using D2D the traffic load is channeled to communication between devices and reduces the burden on the main network.]]>

The simulation model implemented in this study uses Ansoft HFSS 14.0 software. HFSS stands for high frequency structure simulator is a pioneer in the use of finite element method for electromagnetic wave simulators that implement tangential vector finite elements, adaptive meshing and Adaptive Lanczos-Pade Sweep (ALPS) technology. By using HFSS 14.0 simulation, the axial ratio value of 35.0359 dB that means linier polarization. For the value of s-parameter -21,1851 db and VSWR value approaches 1, that is 1.5195 db. The gain value obtained is 0.7469 dB, the gain value needs to be optimized by using a metamaterial to get a good gain.]]>

<![CDATA[DOTA 2 is one of the eSports that are in great demand both by the general society and the game professional communities. They compete with each other to develop the best strategy to defeat all enemies they faced. In order to develop the best strategy, a good and accurate analysis system is needed. Data mining can be used to solve these problems by digging valuable information from dataset using certain method. Prediction method is one of the methods in data mining that is most appropriate for finding the winning predictions for the DOTA 2 game. One method that is quite simple and can be used is Naive Bayes. The results of this study indicate that Naive Bayes can make predictions well with an accuracy of 98,804 %. The data used in this research as much as 50000 that obtained from open data. It is expected that this research can assist players in providing information for developing game strategies.]]>

<![CDATA[Earth stations are built to monitor the presence of satellites starting from satellite data, monitoring satellites, and carry out orders and corrections if needed. On the earth station there is a satellite data receiving antenna, the more elevation angle of the current satellite data receiver antenna can affect the time duration of the satellite data. The purpose of this research is to apply the Artificial Neural Network (ANN) method to design a time optimization system for satellite data at the LAPAN Pekayon earth station, East Jakarta. The data used as input is the elevation angle. The benefit of this research is expected to make it easier for operators and technicians to measure the time optimization of satellite data at earth stations. The best training results with learning rate = 0.2, error = 0.0001, max. epoch = 100000, neuron hidden layer = 15. The MSE value obtained is 0.0001 reaching the goal at epoch 68810. Regret the training / training reverse sequence reaches 0.99878. The best test result is to use learning speed 0.2 hidden layer neurons 15 comparison of training data = 54 and test data = 18. The accurate result is exactly the same as the specified error, namely 0.0001. The difference in the average target duration is 3 seconds compared to the ANN target. Artificial Neural Network (ANN) with the back propagation method of training function gradient descent (traingd), was successfully used to an optimization system for satellite data acquisition time at earth stations.]]>

<![CDATA[Electricity is one of the basic needs of the community. The ability of PLN to provide electricity to the Indonesian people is still an obstacle and a challenge. On the other hand Indonesia has so much potential for water that has not been utilized optimally, which is around 75,000 MW and which is currently utilized only at 10.1% or 7,572 MW. Micro hydro power (MHP) with each 5 MW MHP in 2014. This study aims to utilize the remaining water flow from the existing mill for the installation of the second wheel to obtain maximum power. Experiments were carried out using equipment such as embedded iron fast pipes, waterwheel 1 and 2, pulleys, and generators. Installation on the end of the pipe against pin 1 uses the over-flow method to obtain optimal power. The average rotation speed of the generator for mill 1 is around 1500rpm and for the mill 2 around 1000rpm. The final result of this study, for generator 1 on wheel 1 can run smoothly and produce the appropriate output voltage of 220V, for generator 2 the generator 2 the output generator cannot be optimized because the generator component we use requires a minimum of 1500rpm to run it.]]>
