In this paper, two new 60 GHz antennas design are successfully performed, including a single patch antenna and MIMO antennas with 2X2 and 2X6 elements for a 5G wireless communication network. The proposed Quasi-Yagi antenna size was 7.1 mm ×2.6 mm and stacked series planar was 13.85 mm ×1.8 mm and were printed on 0.787 mm-thick Rogers Duroid RT5880 substrate with dielectric constant of = 2.20 and loss tangent (tan δ) of 0.0002. Both antennas were designed and simulated using CST Microwave software and operated at 60 GHz. All proposed antenna-elements showed a very consistent return-loss (S11) characteristic, the bandwidth impedance of 4.61 GHz and 8 GHz were obtained for Quasi-Yagi antenna and stacked series planar antenna, respectively. The return loss reached more than −25 dB at 60 GHz, and the gain reached 5 dB.

Supercapacitors are a new technology that promises to be an electrical energy storage device in the future. Supercapacitor electrodes derived from activated carbon have high power and energy capabilities because they have a high surface area, high conductivity, and the ability of activated carbon to optimize the properties of supercapacitors. This paper also describes the manufacture of supercapacitor electrode materials by utilizing activated carbon from various biomass and supercapacitor performance compared to batteries. The effect of the activation method, type of activator, type of electrolyte, carbonation or pyrolysis process used will determine the energy and density of energy produced by the supercapacitor. In this case the process of forming an electric double layer on the surface of the electrode was also reviewed and the effect of the type of electrolyte used on the performance of supercapacitors. The use of organic electrolytes can improve the performance of supercapacitors but in the ecological terms the use of acetonitrile solvents is not good for the environment. In this paper we recommend the simplest and lowest-cost fabrication technology but has better performance than the technology of poets such as lithium and alkaline batteries.

This paper presents a simulation of a buck converter using pulse-width modulation (PWM) signal frequencies and duty cycles generated by an Arduino microcontroller for solar panel application. The frequencies used are 23 kHz, 62.5 kHz, 92 kHz, and 186 kHz. A circuit is composed from the results of calculating the buck converter design needed to operate with continuous current mode at minimum value of the component needes. Load used in the circuit is a single Li-ion cell which has a voltage of ~4.2 V, with a simulated panel specifications are 18.36 V and 0.56 A. The I-V characteristics of the converter are studied at input and output in changes of duty cycle and frequency to obtain the overall operating characteristics for each frequency. Overall, the panel current increases before the peak power voltage and decrease after. A peak current of ~1150 mA occurs at frequencies of 23 kHz, 62.5 kHz, 92 kHz, and 186 kHz for duty cycles of 50%, 35%, 35%, and 20%, respectively. Thus, 23 Khz PWM signal is the optimal frequency to drive the circuit beecause of the wide duty cycle operation. In addition, the values of both input current and voltage increase along with the duty cycle rate according to the character of the corresponding I-V curve.

NEEVA is a hash function algorithm which uses a sponge function as its structure. It is designed for sensor nodes in wireless sensor network (WSN). In this paper, we apply correcting block attack on Reduced NEEVA which is simplification of NEEVA. The result shows that many collision pairs were found in Reduced NEEVA. Based on the analysis, we indicate that the unbalanced Feistel structure give impact on the collision to occur

Visualization is very effective when we analyze the big data. When we handle with time series data for a long period, especially visualization is needed. In the paper, we shall illustrate change of the whole trend on time series data as shapes. The method we used is statistical shape analysis which can extract the Affine and non-Affine transformations from the deformation. The method is also helpful to see a local movement of each data sample, compared to other neighbors. In the paper, we illustrate the whole trend change using the Indonesia province comparison concerning the total fertility rate and the under five mortality rate. From the visualization, we found that the relationship between the data have been relatively stable and shows a linear relationship, finally in 2012.
