Published: November 2019

Abstract
A novel consequent-pole permanent magnet (PM) motor is proposed in the paper, which has an image pole pair for every pole pair of N and S. The three-phase synchronous impedances of the motor are balanced owing to the rotor configuration. In addition, it is possible to carry out field weakening with less d-axis current, which leads to a highly efficient operation in a high-speed range. This paper describes a basic principle and its operation characteristics of the newly proposed consequent-pole PM motor.

Abstract
Landslide mitigation may be performed in various methods, such as by identifying the weathering degree in order to determine the position of slip surface. Slip surface is imaginary plane beneath surface dividing the moving part of slope mass with the rest, In short, it may also be defined as the weakest zone where the landslide may occur. Therefore, slip surface is the main object of this research which result may be used as a reference for further mitigation step. This research is conducted in the landslide case of Mount Pawinihan, Banjarnegara. The research is conducted by identifying the weathering degree of heterogenic material based on the British Standard EN ISO 14689-1. Engineering properties sampling was conducted after identification of weathering zone and use systematic sampling base on zone of weathering. The research result shows that the landslide soil mass under study may be divided into four weathering zones exposing on surface, while the position of slip surface may be identified in the weathering zone 3 (moderately weathered). This zone is a boundary of rock and soil condition.

Published: November 2019

Abstract
Dual-Channel Supply Chain (in short DCSC) is a business structure that integrates offline channel and online channels in distributing their products. In DCSC, a consumer may switch easily from one channel to another which can make a conflict between both channels because they have the same potential consumer. This study aims to examine the factors that cause consumers to switch shopping channels in the DCSC structure. Push-Pull-Mooring (PPM) is applied to investigate consumer channel switching behaviour that is implemented in a service company. Push variable includes information searching behaviour, perceived service quality, satisfaction, and perceived price. The pull variable includes switching cost, attitude toward switching, subjective norm. Additionally, mooring variable comprises of alternative attractiveness and responsiveness. The findings indicate that all three variables have a significant effect on switching intention. However, neither of mooring factor on the relationship between push and switching intention nor between pull and switching intention show moderating effects. Partial Least Square-Structural Equation Modelling (PLS-SEM) is applied to analyse survey data from 250 respondents. The result of the interrelationship among variables could be potentially applied in determining operational and tactical strategies to anticipate the volatilities in consumer behaviours.

Authors: RPriandana Eka , Noguchi Toshihiko 
Published: November 2019

AbstractThis paper proposes an advanced technique in generating a pure sinusoidal output current waveform for the high number multilevel lsingle-phase current-source inverter (CSI) with reduced switching device count. Previous multilevel CSI development proposed a new technique in generating pure sinusoidal output by compensating the staircase current with a linear current. This linear current compensation intends to reduce the output filter capacitor size without sacrificing inverter efficiency. However, this hybrid multilevel CSI would give higher efficiency and performance if applie in high number of levels. Consequently, the system needs high switching device count. Too many switching devices utilization will decrease the performance and the power density of the CSI as well. Therefore, this technique is introduced and only possible to be realized if the number of levels is higher than 5-level. By applying multilayer stagemethod while managing the DC current module activation sequences, the high number of levels CSI can be constructed with only using few DC current modules. As a result, according to the computer comparison simulation, the implementation of the proposed technique delivers relatively equal results compared to the conventional one just by utilizing fewers witching devices.

Abstract
Electrical energy is very important for everyday life. The need of electrical energy increasing every year. However, the solar panel source has a weakness. The output power of solar panel is still fluctuating depending on ambient temperature and solar irradiantions on the solar panel. Irradiation is the radiant of energy that comes from the sun. To overcome the problem the Maximum Power Point Tracking is needed so it can make solar panel work at its optimum point. This Maximum Power Point Method is looking for the largest current and voltage read by solar panel using the Lagrange Interpolation method. By using Maximum Power Point Tracking, the output power is expected to be optimal with constant voltage and current so that the battery’s lifetime is not damaged quickly. This method can track Maximum Power Point whenever irradiation changes occur. The converter used in this Maximum Power Point Tracking is the SEPIC Converter. This converter can convert DC to DC voltage in higher or lower voltage without changing its polarity. In this paper, Lagrange Interpolation method has average error in output power of 1,96%.

Published: November 2019

Abstract
This study discussed the coordination of working time of Over Current Relay (OCR) incoming and OCR feeders on a substation with a 60 MVA transformer, 150/20 kV which supplies 4 feeders. OCR working time coordination was done to compare the performance of OCR using 3 time characteristics : standard inverse (SI), very inverse (VI) and extremely inverse (EI). OCR feeder 1 (OCR F1) was chosen to coordinate work time with OCR incoming because feeder 1 (F1) is the longest (6.10 km) between the 4 feeders so that it has the largest impedance. Phase to phase short-circuit current was calculated at a distance of 0% (bus 20 kV), 1%, 25%, 50%, 75% and 100% length of feeder 1. The short-circuit current was used to calculate the time multiplier setting (tms) also working time (tOCR) OCR incoming and OCR feeder 1 with time characteristics SI, VI and EI. From the comparison analysis of OCR incoming and OCR feeder working time coordination, it was proven that the time characteristics of SI had the best performance by considering OCR feeder working speed and OCR incoming work speed as back up.
High-voltage power supply for x-ray computed tomography and time-delay compensation of cockcroft-walton circuit
Authors: Kajiuchi Yuki , Noguchi Toshihiko 
Published: November 2019

Abstract
In recent years, an image diagnostic apparatus using X-ray is intensively investigated to reduce the radiation exposures amount. Above all, high-speed control of the high voltage generator to control the X-ray output is a very important issue. A Cockcroft-Walton circuit (CW circuit) is one of the method to generate the high voltage output. However, it has problem of the long time delay in the output response due to the huge capacitive component of the CW circuit. Therefore, it is required to achieve the stable output voltage with a quick transient response, which can be obtained by the time delay compensation technique of the CW circuit. This paper proposes an application of a Smith method to compensate for the time delay of the CW circuit output to reduce the undesirable excessive radiation exposure. AS a result of verification through the computer simulation, it has been confirmed that the overshoot of the output voltage can effectively be suppressed and that the optimal response can be realized without sacrificing the high-speed response. The paper indicates some possibilities of further improvement of the CW circuit output response by introducing the more precise compensation technique to the X-ray computed tomography.

Published: November 2019

AbstractCurrent source inverter operates producing a predetermine ac current from dc current inputs. In practical, ac current waveform will have harmonic contents appeared in the frequency spectrum. Some factors may affect these harmonics contents such as voltage drops occurred in the power devices of controlled power switches, and voltage drops caused by the resistances of power inductor and conductor. The dc current sources usually generated by using power inductors connected to dc power source. Another factor that can escalate the harmonics is the current ripples of dc current sources. To regulate the dc current sources flowing in the inductor, controlled switches and current controller are required. This paper proposed a novel strategy to minimized current ripple of inductors by applying single core inductors. Some test results of computer simulation were presented in the paper.

Abstract
The performance of dense wavelength division multiplexing (DWDM) system in optical fiber network communication is influenced by various factors, one of them is called a nonlinear effect. Stimulated Raman Scattering (SRS) is one of the nonlinear effects that occur due to a high-power level utilization, causes a signal scattering phenomenon that grown exponentially as the power increases. This works aimed to analyze the bit error rate (BER) and Q-factor performance of DWDM systems that suffer from SRS nonlinear effects on optical power launch, channel spacing, and bit rate variations. Observations were made on a model of 8-channels DWDM, over 100 km optical fiber cable with channel spacing variations of 50, 100, and 200 GHz. The DWDM system was designed using the erbium-doped fiber amplifier (EDFA). The system performance was observed with optical power launch variations of -6, - 4, -2, 0, 2, 4, 6 dBm, and bit rates for 10 and 40 Gbps. Based on the result, the 6 dBm optical power launch, with 200 GHz channel spacing, and 10 Gbps data rates, provides the best performance of 1.78 x 10−151 BER values, and Q-factor of 48.57. The observation of nonlinear systems performance is measured with an optical spectrum. Changes in the value of optical power launch, channel spacing, and data rate had affected the performance of the DWDM nonlinear system.

Abstract
Aquaponics is an activity to cultivate plants and fish. Giving the organic liquid fertilizer as a nutrient enhancer will improve the quality of catfish and lettuce yields. However, this causes the water to become dirtier. The deteriorating water is characterized by the TDS value in aquaponic ponds exceeding 500 PPM. If the TDS value exceeds 500 PPM, water drainage will be applied. For treatment of aquaponic, experts use manual control. The system is designed to solve it. The method used in this Final Project is the study of literature to find the basic theory in aquaponics and analyze the problems. The next thing to do is designing the system, starting from the design of automatic control systems to remote monitoring systems. Afterwards, testing tools is conducted to see whether the system is able to run well. Based on the test results, the system can run well; however, a number of deviations are found, including the RTC test showing a delay time for 00.02.10 of RTC compared to the national standard time and an error of 2.4% found on a calibrated TDS sensor testing. The success rate of sending monitoring data is 100% of Antares connectivity testing.
