Authors: Yoga Permana Nikolas , Riyadi Slamet 
Published: February 2020

AbstractThe development of power electronics especially the inverter is required to be able to convert DC voltage to AC voltage. Multilevel inverters can provide an AC voltage power output, which has lower THD and better sinusoidal waveform. In this case, the voltage which is not sinusoidal and contains higher THD can shorten the durability of applied electronic devices. IEEE has a standard that has been established as a general guideline for the use of power supply standards which is not more than 5%. The modified SPWM technique is able to provide a good quality of output by shifting the phase of the carrier signal. In this paper is proposed diode clamp five-level inverter topology based on the modified SPWM, the whole system has been simulated through PSIM software and the laboratory tests have been carried out to verify the proposed method. Several waveforms are shown to validate the performance of this five-level inverter.

Published: February 2020

Abstract
SF6 gas is gas as a filler material for insulating material in Gas Insulated Switchgear. The Kyoto Protocol issued amendments to limit and reduce the use of SF6 gas in various applications, especially as gas isolation applications in substations because SF6 is gas that contributes to the greenhouse effect, the occurrence of global warming and the cause of the ozone layer depletion. This study investigated the use of CF3CHCl2 gas as a new gas to replace SF6 gas as insulation gas. The use of mixture N2/CO2 gas aimed to reduce the main gas concentrate if it leaked into the air and to reduce the cost of procuring the main gas material. The high voltage test showed that CF3CHCl2 gas mixed with N2/CO2 gas was able to withstand a breakdown voltage of 752-837 kV. The ability to withstand the breakdown voltage of the N2 gas mixture is 9 kV-26.7 kV lower than the CO2 gas mixture. The techno-economic value of the use of CF3CHCl2 gas mixed with N2/CO2 gas gives a cost of 5.18 times cheaper than the cost of procurement SF6 gas. The use of CF3CHCl2 gas mixed with N2 gas gives a cost of 1.01 times more expensive than a cost of the use of CF3CHCl2 gas mixed with CO2. In the future, the priority gas is CF3CHCl2 gas as a new gas material that needs to be considered as a potential alternative gas to replace SF6 gas.

Published: February 2020

Abstract
DC motor speed can be achieved by changing the armature voltage fed through converter that generally employed with conventional PID. However, conventional PID controller has some disadvantages such as the high starting overshoot and sensitivity to controller gains. On the other hand, fractional order PID has potential to accomplish what conventional PID cannot. In this study, fractional order PID controller was applied to control speed of DC motor. By calculated error that occurred by reference speed and actual speed, fractional order PID brought motor run at desired speed. The parameters of fractional order PID controller (proportional constant, integral constant, derivative constant, derivative order and integral order) are optimally tuned by using Genetic Algorithm, and the optimization performance target is based on Integral Time Absolute Error (ITAE) criterion. Oustaloup’s approximation method is used to approximate the fractional order differentiator and integrator. This controller performances are tested in simulation mode using MATLAB/Simulink. Speed response of motor DC are compared between fractional order PID and conventional PID controller. The result of fractional order PID controller could reduce overshoot, settling time and steady state error. With this result, show that fractional order PID controller perform better than conventional PID controller.

AbstractThe inverter is very important to be implemented on a power plant system, the principal operation of inverter is a power conversion from DC to AC output. A five-level inverter produces a high-quality total harmonic distortion output side. This paper presents a single-phase five-level inverter using a sinusoidal pulse width modulation (SPWM) controlled in dual buck DC-DC converter and full bridge inverter. The proposed topology is a hybrid converter: dual buck DC-DC converters to generate SPWM voltage level with high frequency and full bridge inverter to generate polarity. This method is very effective to predict the high frequency power semiconductor in dual buck DC-DC converters. The other side the full bridge inverter just need a low frequency. By this method, the gating signals for power semiconductor switches are generated by employing simple pulse width modulation. The fist verification of this topology is by simulation using PSIM software. Finally, a microcontroller dsPIC30F4012 is used in laboratory experiment for the last verification.

Published: February 2020

Abstract
In the New Paradigm of Industry 4.0, the main concern of high flow information transmission is security disruption. The transmission process should secure the information transmitted. Especially for secret information found out by nobody. One of the methods used to improved information security is the information hiding process. The hiding technique often applied is Steganography. In this technique, a multimedia data format such as the digital image embeds information. The problem occurs when the secret information is a digital image. Stored an image into another image will cause data distortion and the information will be damaged. These problems can be solved by improving the steganography method for digital images. Improvement of the steganography method in this study uses a bit manipulation technique on the Least Significant Bit (LSB) method. The secret information represented by the digital image will be hidden in a container image. The hiding technique method worked by manipulating the intensity value of the image in the sequence of binary bit format, so the container image intensity value can be used to hide many digital images. The result of this research is a steganography technique allowed to store three images in one image container at one time. The results of the improvement method can protect the intensity values of the container image from some failure. The results of this study also show that data integrity is maintained even though the value of image intensity changed by the bits of hidden images.

AbstractAt this time the timber with good quality has been difficult to obtain, so the wood is increasingly rare for building construction. To reduce deforestation due to logging for construction materials, it is time to replace wood with bamboo. Laminated bamboo is an engineering building material that has a character like wood. Laminated bamboo structures can encourage the replacement of wood, steel and concrete materials so that the development of laminated bamboo technology can revolutionize the use of bamboo in construction. One of the weaknesses of the laminated bamboo beam structure is the adhesive line between the bamboo lamina. Mechanical lamination using a shear connector prevents horizontal slip between the bamboo lamina. Incising method is a method that makes the adhesive as well as the adhesive as well as the shear connector. Dendrocalamus asper research material with an average age of 4 years. The testing shear strength and tensile strength of bamboo block lamination was carried out based on ASTM D143 (2002).

Published: February 2020

Abstract
This article reports the oxidation of cumene by H2O2 in the presence of CO2. It describes the role played by carbon dioxide on the course of the reaction. The reaction was catalyzed by unsupported Co1.5PW12O40 and supported on activated carbon. The prepared materials were characterized by ICP, IR, XRD and UV. Analysis of the reaction products by gas chromatography coupled with mass spectrometry and gas chromatography showed that 2-phenyl-2-propanol and acetophenone were the main products of the reaction. Activated carbon significantly increases conversion by increasing Co1.5PW12O40 accessibility to cumene molecules. The improvement in the conversion and selectivities of 2-phenyl-2-propanol and acetophenone by the use of the oxidizing system H2O2/CO2compared to the use of H2O2 alone or CO2 alone is due to the role of the percarbonate entity

formed by reaction between H2O2 and CO2. Oxidation by large amounts of H2O2 decreases the conversion by decreasing the solubility of cumene in the resulting aqueous medium. An increase in the reaction time resulting in a decrease in the concentration of H2O2 and leaving the effect of the predominant CO2 accentuates the cracking reactions.

Abstract
A simple and direct method has been developed to grow zinc oxide (ZnO) nanorods (NRs) on a fluorine-doped tin oxide-coated glass (FTO) substrate. Firstly, spray pyrolysis deposition method is applied followed by dipping the substrate in a solution of ZnO growth reagents. The morphology, structure, and optical properties of the obtained thin film are investigated. The results demonstrate the successful synthesis of the ZnO NRs on FTO substrate. The NRs have a hexagonal rod like structure with diameter and length of 240 nm and 670 nm, respectively. FTO/ZnO NRs exhibited absorption of UV wavelengths and high transmittance in visible light region, with energy bandgap (Eg) of 3.2 eV. The characteristics of the FTO/ZnO NRs film can be explored in photovoltaic applications such as dye-sensitized solar cells.
