Ring Resonator has become one of the most interesting research topics nowadays since this device has high finesse value at resonance frequency and high sensitivity as well. There have been many scientific publications in the device's characteristic dynamic conditions, structures (single, multi and combination), and their applications as well, such as sensors, filters and others. The performance characteristics of double coupler structured single ring resonator has been discussed so far but the effect of coupling coefficient variation has not been discussed yet. Meanwhile, in previous research we have investigated the effect of coupling coefficient variation on single coupler structured single ring resonator. Now, we explore further the effect of coupling coefficient variation on the power transfer function output of a double couplers structured single ring resonator. Besides, single beam and double beams inputs are utilized to get the transmission powers as the output characteristics from both of drop and through ports of the ring resonator. The simulation results show, for the drop port output, as the higher coupling coefficient is, the peak of the power transfer function output gets higher for both the drop port output of single beam input and double counter directional inputs, but the double counter directional inputs, shows the peak of the power transfer function output much higher compared to its of the single beam input. Meanwhile for through port output, the result with double parallel inputs configuration shows a bit different behavior with its of single beam configuration, where as the result of the double parallel input configuration exhibits peak of the power transfer output almost similar to the simulation result utilizing single ring resonator with single coupler configuration that has already published previously. This simulation works may be useful in the design of resonator performance when transmission power is one of the important parameters to be considered.

Plasma treatment could generate UV radiation, chemical reactions, and radicals that be able to modify the properties of a wide range of materials, including water. Water treated by plasma produces reactive nitrate-nitrogen and oxygen species that useful for the fertilization of agriculture soil and plant growth. Moreover, the water treated by plasma can be used for increasing postharvest quality of agriculture products. In this study, plasma treatment of water has been used to stimulate the germination of agricultural seed, i.e. water spinach (Ipomoea aquatica). The results demonstrate that the water spinach seeds treated by plasma-treated water not only had better germination rate and germination index, but also had a higher length index and weight. Compared with control sample, the germination rate and germination index of the plasma-treatment sample improved by 16.96% and 28.57%, respectively. Characteristics of length index also increase to 425.46. In addition, fresh weight of plasma-treatment sample was higher than the control sample by 33.3%. These results indicated that plasma-treated water might be potentially applicable for increasing water spinach plant growth.

5G air interface system is expected to provide an efficient usage of system resources and available spectrum. Higher main-lobe and lower side-lobe power are keys to achieve its efficiency. Filter Bank Multi-Carrier (FBMC) has been actively investigated for years and capable to enhance current system. This paper aims to study and to simulate the spectrum performance of FBMC utilizing Mirabbasi-Martin filter with a variation of overlap factor g = 3, 4, 5, 6. The results are comparing between the bandwidth, main-lobe power and side-lobe power of FBMC and OFDM. The FBMC g=4 is giving the most optimum performance because it performs higher main lobe power at a comparable OFDM bandwidth. Subsequently, we conduct computational simulation in the practical case of mobile network operator working at 945 MHz–952.5 MHz. The results have indicated a significant bandwidth efficiency and lower side-lobe power outside the spectrum band allocation.

External Quantum Efficiency (EQE) measurement is one important method that is implemented to observe solar cells' behaviour in a specific range of wavelength. This research measured EQE in different type of solar cells: silicon, dye-sensitised solar cell (DSSC), and perovskite solar cell. The objectives of this research are to understand the correct EQE measurement method and to understand the factors that affect EQE result on the three types of measured solar cells. Dedicated illuminator, monochromator, and lock-in amplifier, as the main equipments, were used in the experiments. The method used was the latest version of the standard for doing EQE measurement, which is ASTM E1021-15. The spectral responsivity (SR) has to be measured first before calculating the EQE value. This value was then validated using current density value obtained from current-voltage measurement. As a result, the silicon has the highest EQE among them all, but it is the perovskite which has the same profile with standard solar irradiance spectrum. It means that perovskite solar cell has the potency to maximise the utilisation of solar irradiance. Some critical points of measurements had also been identified during research. First is the providing of the testing vacuum chamber to minimise the influence of the environment. Second is the importance of regular calibration of the reference photodetector. Third is the illuminated area of reference photodetector. Fourth is the nonlinearity of SR versus light intensity in the DSSC.

This paper proposes a novel relative wavelet bispectrum (RWB) approach for EEG signal feature extraction method to differentiate the signal between the alcoholic over the non-alcoholic subjects. Firstly, the EEG signal is calculated for its autocorrelation frequencies as the basic step in the bispectrum calculation. Then, the discrete wavelet transform (DWT) is applied substituting the FFT which usually is used in the bispectrum calculation. Lastly, the relative value of each frequency band is calculated for both the approximation and the details parts, producing the RWB. The proposed methodology is implemented in an alcoholic automated detection system using 1200 data samples from UCI EEG Database for alcoholism. Based on the experiments, the setting value of lag in the autocorrelation calculation was evidently very influential on the recognition rate obtained, i.e. the maximum value for the lag was the best. Using cross validation, the highest results from RWB feature extraction method with ANN classifier achieved about 90% recognition rate.

Biofuel is one of the best alternative solutions to fulfill the fuel demand, due to the increasing of energy needs and the limited reserve of fossil fuel. Biodiesel, a liquid biofuel and derived from biomass, is produced from vegetable oil, animal fat and other sources to replace diesel oil. Indonesia has been producing biodiesel from vegetable oil, such as Crude Palm Oil (CPO). Because most of Biodiesel feedstock is derived from plant, which is also utilized for human food, it will become a major problem for food security issue of the country. Furthermore, the feedstock production also has some threats regarding to the limitation of land use for feedstock cultivation and infinite export commodity due to high export demand and promising price. The research aims to assess the production of CPO as the Biodiesel feedstock in Indonesia with all related constraints and without threating the food security. Using Dynamic Modeling with Stella Software, the CPO production is modeled with influence variables and their correlations, such as feedstock demand for export, food and Biodiesel, feedstock consumption, land, productivity and policy regarding CPO production, Biodiesel demand and Diesel oil import. The simulation results, that in the year 2019, CPO Production for energy will not be sufficient to fulfill the Biodiesel Demand, but if the reserve of CPO Supply is utilized for energy, there will be plenty biodiesel produced to meet the demand, without interfering the food security and export commodity. The Government should synchronize the distribution of CPO by making list of priority order (food, fuel, export) in order to attain food and energy security. If B30 mandate is being accelerated, CPO export commodity should be limited to maximum 74.7 % of CPO Production in order to meet this mandate. With this scenario, diesel oil import could be reduced about 1.7–1.8 million kL.

Time-domain charge pumping, which monitors transient currents during the charge pumping process, is a novel technique for analyzing interface defects of semiconductors. In this paper, we make a brief introduction about our recent works on the development of the time domain charge pumping, aiming at the detailed analysis of metal-oxide-semiconductor interface defects. We in particular show that the time-domain charge pumping enables us to obtain capture cross sections of electrons and holes independently, and to resolve electron-emission spectra into two components with different time constants. It is also shown that it allows us to investigate complicated current flow during the charge pumping process in silicon-on-insulator devices.

The Advanced Encryption Standard (AES) became the standard for encryption to protect the sensitive information. With the increasing use of portable and wireless devices and demanding information security needs in embedded systems, prompted efforts to find fast software based implementation of AES encryption/decryption capable of running on resource constrained environment in terms of processor speed, code space, energy usage and in particular those portable devices that have 32-bits ARM Cortex-M3 processor. In this paper, we propose an implementation of AES on ARM Cortex-M3 processor with minimum memory will be useful for deploying it in low cost applications. The algorithm is compiled using LPCXpresso IDE targeting into an ARM LPC1769 processor board. The results are presented in this paper for key length of 128 bits. After AES encryption the cipher voice is sent through communication module to another node, while receiving cipher voice through communication module the plain text is obtained by AES decryption.

At the moment, PT. PLN (PLN) as national electricity company have to visit customer place to disconnect or switch off (permanent break) the KWh meter if the customer did not pay the billing on time. It is important to design of a system that could automatically disconnect electricity that flow to customer temporary or/and permanent when the bill is not paid by customer while deadline is overdue. In this research, M2M as KWh meter controlling system will be designed and evaluated its performance. The proposed system is designed to minimize the time for breaking and improve PLN services. The proposed system consists of KWh meter, actuator and sensor, communication devices and application. The command to actuator to disconnect or switch off (permanent break) is based on the billing status of the customer at deadline of payment period. If the customer didn't pay the billing until deadline at the second month, the electricity will be disconnected to customer KWh meter, while the KWh meter will be permanent broke (switched off) if the customer didn't pay the billing until the deadline of the third months. It is shown from the tested results, that the proposed KWh meter is working properly. It is also shown from the tested results of the KWh meter controlling that the response time to device to disconnect or switch off is shorter than the time response SMS notification that sent to the customer.

Thermal ablation is conducted by utilizing temperature changes to destroy the abnormal tissue or restore its function. The latest technique in thermal ablation is Microwave Ablation (MW Ablation) that rely on the propagation of electromagnetic waves that is able to increase the temperature of a tissue rapidly. Changes in temperature during the ablation process will reduce the water content in the body tissue (78% of the liver tissue is composed of water) and affect the value of permittivity and conductivity of the tissue. These changes cause the impedance matching of the antenna applicator also change during the ablation process. The change on impedance will make the system does not match with the previous resonant frequency. In addition, the microwave ablation applicator, which is designed for specific frequencies (2.4 GHz and 915MHz) with narrow band characteristics will be suffered from aforementioned phenomenon. Meanwhile, according to the previous studies there are other prominent resonant frequencies that used for MW Ablation, i.e. 1.9 GHz, 6 GHz, 9.2 GHz and 10 GHz. Therefore to accommodate some of the frequencies that are widely used in microwave ablation technique and to tackle the problems arising from the reduced transmission efficiency, then an applicator that has ultrawideband (UWB) characteristics is proposed. In this paper, we design an applicator, which has the characteristics of UWB by modifying the ground plane of the applicator by a hexagonal-sectioned coil. The applicator is designed on a FR4 substrate and numerically simulated with liver phantom by using CST Microwave Studio. The proposed applicator is able to have wide bandwidth by 8.1 GHz, with lower frequency (fl) 1.84 GHz and higher frequency (fh) 10 GHz.
