<![CDATA[Belakangan ini, kepopuleran dari PLTAn (Pembangkit Listrik Tenaga Angin) kecepatan variabel yang berbasis DFIG (Doubly Fed Induction Generator) telah melampaui PLTAn kecepatan tetap. Kepopuleran ini terutama disebabkan karena dalam operasinya, kecepatan rotasi generator dari PLTAn kecepatan variabel yang berbasis DFIG dapat bervariasi pada interval yang jauh lebih lebar dibandingkan PLTAn kecepatan tetap sehingga ekstraksi energi angin dapat dilakukan dengan lebih optimal. Untuk mengevaluasi performa keadaan mantap (steady state) dari suatu sistem tenaga listrik, seluruh komponen-komponen sistem (termasuk PLTAn) harus dimodelkan dengan baik dan benar. Makalah ini mengusulkan model keadaan mantap DFIG untuk analisis aliran daya sistem distribusi tenaga listrik. Usulan model tersebut diperoleh berdasarkan rumusan-rumusan daya dari PLTAn yaitu: daya turbin, daya-daya rotor dan stator DFIG, serta keluaran daya listrik PLTAn. Model yang diusulkan ini dapat diaplikasikan pada berbagai mode operasi faktor daya DFIG. Untuk memverifikasi usulan model, makalah ini juga membahas studi kasus dimana penerapan usulan model pada suatu sistem distribusi tenaga listrik dilakukan. Hasil studi memperlihakan bahwa pada kecepatan-kecepatan angin antar 5 m/d sampai 12 m/d, keluaran daya aktif PLTAn bervariasi diantara 0,09 MW sampai 2,10 MW. Sedangkan keluaran daya reaktifnya bervariasi diantara 0,03 MVAR sampai 0,67 MVAR (untuk faktor daya 0,95 leading), dan diantara -0,69 MVAR sampai -0,03 MVAR (untuk faktor daya 0,95 lagging). Hasil-hasil penyelidikan dalam studi kasus ini juga mengkonfirmasi validitas usulan model PLTAn yang berbasis DFIG tersebut.]]>

<![CDATA[The conversion of solar energy into electrical can be utilized by using the solar panel, but the energy conversion ratio is still low. Maximum Power Point Tracking (MPPT) is a method used to increase energy production in the process of converting electrical to the solar panel. Artificial Neural Network (ANN) is one of the soft-computing methods that can be applied as MPPT with the advantage of having a learning process, very stable, fast, doesn’t require complicated mathematical modeling, and has good performance. ANN is proposed with input from the short circuit current of the solar panel and is used as a reference for the ANN to reach the maximum power. The process of detecting a short circuit current is indicated by a momentary decrease of the power by the solar panel. The results show the proposed algorithm can reach the maximum power operating point of the solar panel despite the change of radiation. When at maximum power operating point, ANN can hold the value, so the resulting value doesn’t change and doesn’t generate ripple. At radiation of 1000 W/m2 and using 100 WP, ANN can produce a maximum power of 99.97 Watts with a time of 0.063 seconds. ]]>

<![CDATA[In recent years the use of wireless technology is growing rapidly. Not only limited to the use of cell phones but also other wireless devices that use the air media as the information transmission line. The antenna is a very important component in wireless devices because its function is to convert electrical signals into electromagnetic signals and vice versa on transmitting the information in the air. One of the technologies that can overcome this is the use of microstrip antennas. The microstrip antenna is a lightweight, easy to fabricate so that can be placed on almost any type of surface and small size compared to other types of antennas. Because of its properties, microstrip antennas are highly suited to current needs. This antenna can be integrated with other telecommunications equipment in small size. This paper describes the design and realization of microstrip meander-line antenna at working frequency 915 MHz to be integrated on a telemetry measuring device pH meter water. The integration of the meander-line microstrip antenna on the pH meter measurements is capable of transmitting pH data at unobstructed conditions with a maximum distance of 210 meters, and in a blocked condition, a building is capable of transmitting pH data with a maximum distance of 110 meters. ]]>

<![CDATA[Wireless network uses transmission media based on radio waves. This type of networks is mainly useddue to its efficiency and mobility in data exchanging. This paper reports the modeling and simulation of wirelessnetworks based on Cisco Aironet 1130ag access point devices with IEEE 802.11a and IEEE 802.11g standards. Themodeling and simulation are performed using network simulator version 2 (NS-2) that is installed on operationsystem Linux Ubuntu v.10.10. The NS-2 is commonly used and works well in numerous types of network simulation. From simulation, we obtain quality of service parameters by employing several simulation scenarios in terms ofnumber of nodes, distances, and packet data sizes. It can be concluded from simulation results that the IEEE 802.11gnetworks transfer data with better quality than those of IEEE 802.11a networks. Furthermore, the IEEE 802.11gnetworks provide a higher throughput, with smaller amount of delay and packet loss percentage compared to thoseof IEEE 802.11a networks.]]>

<![CDATA[The line follower robot is a mobile robot which can navigate and traverse to another place by following a trajectory which is generally in the form of black or white lines. This robot can also assist human in carrying out transportation and industrial automation. However, this robot also has several challenges with regard to the calibration issue, incompatibility on wavy surfaces, and also the light sensor placement due to the line width variation. Robot vision utilizes image processing and computer vision technology for recognizing objects and controlling the robot motion. This study discusses the implementation of vision based line follower robot using a camera as the only sensor used to capture objects. A comparison of robot performance employing different CPU controllers, namely Raspberry Pi and Jetson Nano, is made. The image processing uses an edge detection method which detect the border to discriminate two image areas and mark different parts. This method aims to enable the robot to control its motion based on the object captured by the webcam. The results show that the accuracies of the robot employing the Raspberry Pi and Jetson Nano are 96% and 98%, respectively.]]>

<![CDATA[The photovoltaic grid-connected business opportunity offers challenges to power quality and voltage fluctuations in the distribution system. The purpose of this study is to optimize the location and power capacity of the grid-connected photovoltaic so that the voltage values are in accordance with the operating standards and meet the requirements of the connection techniques in the distribution system. The distribution system tested is the 69 Buses radial distribution feeder. The optimization uses three constraints namely voltage constraints, active power capacity constraints and total active power capacity constraints of the Grid-Connected Photovoltaic. The Optimization is carried out by considering the value of the percentage of the total active power of the Grid-Connected Photovoltaic capacity to the total load in the distribution system. The optimization results in the first simulation indicated seven grid locations with a total active power of 1.156 MW (38% PV) and produced a fitness value of 0.029. The second Simulation showed 7 locations with a total active power of 1.243 MW (41% PV) and produced a fitness value of 0.023. The Third simulation was identified with 11 locations with a total active power of 1.385 MW (46% PV) and produced a fitness value of 0.022. The best fitness value is the lowest value of the active power losses. The entry of a number of the Grid-Connected Photovoltaic System with distributed location can increase the voltage level in the distribution system.]]>

<![CDATA[Epoxy resin has been developed as an insulator material on the distribution and transmission line. In its development, the basic composition of DGEBA epoxy resin with MPDA as hardener is hydrophilic. Silane is added to improve the surface properties of materials to be more hydrophobic. To reduce the volume of epoxy resin as base material, silica sand from PLTP Dieng is added as filler. This paper presents the results of research on the effect of adding the composition of silica materials from PLTP Dieng upon silane epoxy resin sample to the value of the dielectric loss factor, contact angle and leakage current. Samples were prepared with a sample size 120mm x 50mm x 5mm. Material is composed of DGEBA, MPDA, silanes and silica with a various composition. Sample codes were 10%, 20%, 30%, 40% and 50%. Contact angle and leakage current were carried out according with IEC 587:1984 standards. Measurement of the dielectric loss factor (Tan ) was carried out at the Laboratory of High Voltage Engineering, PT. PLN (Persero) Electricity RD, Duren Tiga Jakarta, using a measuring instrument series M4100 Insulation Analyzer Instrument. The electrodes used in these measurements have diameter of 2.5 cm and 5 cm. The results showed that the composition of silica materials PLTP Dieng upon silane epoxy resin samples affect the value of dielectric loss factor. Based on the results of the measurement, it is concluded that the higher composition of silica materials, the higher value of dielectric loss factor are. Based on these results, it is suggested that the use of silica as a filler must consider the effect on the value of dielectric loss factor. When the dielectric loss factor is high, then the losses in the dielectric material is also high. ]]>

<![CDATA[The influence of the industrial revolution 4.0 resulted in very significant changes. Many companies compete to produce robots that facilitate human work, in terms of energy and time in the process of producing goods. One of the robots being developed is the Automated Guided Vehicle (AGV), a vehicle with automatic control. AGV has high accuracy, easy maintenance, and a long operating time. This study discusses the design and implementation of AGV using 2 motors. The front motor using a servo motor is used for steering to turn right and turn left, while the rear motor in the form of a DC motor is used to regulate the speed of the AGV. The AGV movement system is controlled by computer vision. The AGV problem encountered is that the camera reading distance is close, which makes it less efficient in industrial use. This problem can be solved with a camera connected to a raspberry pi capable of capturing text and images from a distance of 100 cm. The use of computer vision makes the AGV robot easy to move. In this study, the accuracy of the movement of the AGV robot to the trajectory pattern has an average angle difference of 3.09°. The difference in the angle indicates a small error so that the AGV can operate optimally. Infield applications, this AGV is used in the manufacturing industry to move goods. Therefore, the use of AGV is needed because it has high accuracy and small error.]]>

<![CDATA[This article describes the design and implementation of behavior-based robotic (BBR) algorithm on a wheeled mobile robot (WMR) Pioneer P3-DX in a maze exploration mission using V-REP simulator. This robot must trace and search for targets placed randomly on a labyrinth. After successfully meeting the objective, robot runs back to home position using the nearest path. Robot navigation system applies BBR algorithm to reach the target using behavior modules which work simultaneously to obtain the desired robot’s trajectory. The most fundamental behavior which is highly affordable to build on the robot system is a wall-following behavior. To make the robot could follow the wall in a safe, smooth and responsive condition, proportional-integral-derivative (PID) controller is applied. PID controller runs by utilizing the reading of sixteen proximity sensors carried on Pioneer P3-DX robot toward the expected wall distance while the robot is exploring the labyrinth. To ensure the designed system works properly, several tests were conducted, including BBR test and PID controller test. BBR test shows that the system can choose the shortest track when returning to home position. The PID controller test produces robot movement with maximum deviation and settling time for about 0.013 m and 30 seconds, respectively.]]>
