WDM PON (Wavelength Division Multiplexing Passive Optical Network) is used to increase DAS (Distributed Antenna System) network efficiency applied in existing PON network. The Optical DAS is the best solution for power efficiency in the building. Both DAS and PON use WDM to combine the different optical wavelengths. The simulation network configuration locates the WDM de-multiplexer placed at a distance 18 km from the multiplexer. After 18 km, the optical network is divided into two networks, which are DAS and PON. This paper proposes to use 2×1 WDM PON type for DAS. The experimental DAS and PON configuration system is simulated using Optisystem software. The results of Optisystem simulation shows that photodetector output is −34.071 dBm for DAS. LiNbO3 EOM (Electro Optic Modulator) gives a 4 dB power efficiency in DAS network. While the power input of ONU (Optical Network Unit) in PON network is −21.5 dBm. OSNR (Optical Signal to Noise Ratio) of WDM multiplexer were 69.421 dB for PON and 75.922 dB for DAS. The results comply with the standard of ITU-T G.984.2 for GPON (Gigabit PON) System.

Green IT is a concept about wisely, efficiently, and environmentally technology (IT) usage or adoption that exists due to the negative impacts of technology (IT) growth. There are some examples about Green IT applications that are used by the organization (firm) as the support tools of its business processes such as Paperless Office (PLO), E-Meeting, Remote System, and Cloud Computing. Although Green IT applications are used as the support tools of organizational business processes but their strategic benefits are still unknown. Therefore, the research on this paper aims to analyze Green IT applications usage for the firm's competitive advantage strategy. This paper takes the case at PT. XYZ, an Indonesian telecommunication firm. The questionnaire was used as the research instrument on this paper for collecting the research data at the firm's IT Division and the data was analyzed by SmartPLS. The research result on this paper shows Green IT applications usage positively affects the firm's competitive advantage and it is positively affected by perceived usefulness, subjective norm, and organizational culture. The result is also supported by the related themes of the firm's annual reports for the recent years and the various respondents' related positive opinions. Only perceived risk is not proven that it negatively affects Green IT applications usage at the firm. This paper may be used as a reference for the firm's stakeholders to view Green IT applications usage as the firm's important asset for developing the firm's competitive advantage strategy.

The Brushless DC (BLDC) motors are widely used for many industrial applications because of their high efficiency, high torque and low volume. However, the BLDC motor is a multi-variable and non-linear system, so it is difficult to get a satisfying result for BLDC motor using the conventional linear control method like normal PID controller. This paper presents the development and performance analysis of adaptive PID controller Based on Additional Error of an Inversed-Control Signal for Brushless DC motor drives. The adaptive PID controller Based on Additional Error of an Inversed-Control Signal have a parameter adjustment mechanism, better solutions when there are variations in process parameters, learning capabilities and fault tolerance. This paper implements adaptive PID controller Based on Additional Error of an Inversed-Control Signal to solve the problems of non-linearity, parameter variations and load excursions that occur in BLDC motor drive systems. The performance of the traditional PID controller based speed control method is compared with the model reference based speed control for BLDC motor drive system using MATLAB software. Experimental results is presented to prove that the adaptive PID controller Based on Additional Error of an Inversed-Control Signal is capable of speed tracking as well as reduce the effect of parameter variations.

The drain current of the Schottky barrier (SB) MOSFET is modeled mathematically by considering both thermionic emissions and Schottky barrier tunneling from the source to the channel. The drain current is dependent on the Schottky barrier height, but is barely affected by the doping concentration. For the depletion type gallium nitride SB MOSFET with both an ITO source and drain electrodes, the threshold voltage is calculated to be 3.5 V, which is similar to the measured value of 3.75 V, and the calculated drain current is 1.2 times higher than the measured value.

Solar cells have been through many development phases. Silicon is a one of many important materials in solar cell manufacturing. One of silicon solar cell applications which can produce high efficiency is Heterojunction with Intrinsic Thin-layer (HIT) crystalline silicon solar cell. Another alternative of silicon solar cell applications is Heterojunction with Compound Thin-layer (HCT) crystalline silicon solar cell where silicon is coupled with III-V compound semiconductor. n-AlGaAs is used as an alternative from n-AlAs on Heterojunction with Compound Thin-layer crystalline silicon solar cell. Compared to AlAs, lattice constant of AlGaAs is more suitable to the silicon. To increase the efficiency of solar cell the step grading method is used for AlxGa1−xAs layer on the front surface. The optimization of step grading AlxGa1−xAs layer was done by using the wxAMPS software as simulation tool. Simulation results show that HCT crystalline silicon solar cell produce the 16.64 mA/cm2 short circuit current density (Jsc), the 1.05 V open circuit voltage (Voc), the 0.95 fill factor, and the 16.64% efficiency. The power it produces can be used as power source for HGM-111 biosensors.

Deployment of femtocell in macrocell cellular network which forms two-tier femtocell-macrocell cellular network faces more complicated interference problems, since it uses the same licensed frequency spectrum as its macrocell. This paper addresses the interference problems for downlink transmission in such two-tier cellular communication network. In this paper, interference management using power control is proposed in that two-tier network. This paper considers multi-cell cellular network composing of three macrocell systems. Ten femtocells are deployed in each macrocell system. This paper takes worst case for the scenario that is all femtocells and macrocells in downlink transmissions. Simulation for the system without power control was carried out first as a baseline system. Then, two methods of power control called as PC-1 and PC-2 in this paper were explored to reduce the interference effects. The use of two power controls is to take a trade-off, the increasing of quality of service (QoS) in macrocell system while is not degrading much QoS in femtocell system. Both power control methods are based on the estimated Signal to Interference Plus Noise Ratio (SINR). Both of power control methods also ensure that the results of controlled transmitting power will not exceed the maximum or the minimum of allowable transmitting powers. Simulations have been carried out and performance parameter in term of Cumulative Distribution Function (CDF) of SINR have been collected for co-tier (femtocell-femtocell and macrocell-macrocell), cross-tier (femtocell-macrocell and macrocell-femtocell), and the total interferences. The simulation results show that both power control methods outperform the baseline system.

Group Special Mobile Association (GSMA) has set a new standard related to embedded Subscriber Identity Module (e-SIM) technology. The application of these technologies aim to support the needs of new services such as Machine to Machine (M2M) and Internet of Things (IoT). Currently several smart phone manufacturers such as Apple and Samsung start to implement the technology to their products. Provisioning of cellular services in Indonesia are not evenly distributed, both the scope and quality of its network and the difficulty when customers switch services. Based on the potential benefit of e-SIM, we investigate implementation e-SIM in terms of the number of subscriber, Average Revenue per User (ARPU), and cost production. We forecast the number of subscriber using S-curve model, while ARPU and cost production using Quadratic models. We show there are only 19 million new subscribers between 2015–2020 if Indonesia do not implement e-SIM. However, the new subscribers are being double if Indonesia implement e-SIM in the same period. Moreover, ARPU are estimated being large as Indonesia implement e-SIM because e-SIM enables IoT devices.

Hexacopter is a member of rotor-wing Unmanned Aerial Vehicle (UAV) which has 6 six rotors with fixed pitch blades and nonlinear characteristics that cause controlling the attitude of hexacopter is difficult. In this paper, Modified Elman Recurrent Neural Network (MERNN) is used to control attitude and altitude of Heavy-lift Hexacopter to get better performance than Elman Recurrent Neural Network (ERNN). This Modified Elman Recurrent Neural Network has a self-feedback which provides a dynamic trace of the gradients in the parameter space. In the self-feedback, the gain coefficients are trained as connection weight. This connection weight could enhance the adaptability of Elman Recurrent Neural Network to the time-varying system. The flight data are taken from a real flight experiment. Results show that the Modified Elman Recurrent Neural Network can increase performance with small error and generate a better response than Elman Recurrent Neural Network.

The complex problems in the rural area caused the gap in telecommunication infrastructure between urban and rural areas so that technological solution that fit with the rural characteristics are required. Based on the literature, we argue that TV White Space is an appropriate technology alternative for rural conditions. The FCC and ECC have issued standards on the utilization of white space frequencies for secondary purposes that may be adopted by other countries. However, the challenges for developing countries like Indonesia are certainly different from those in developed countries. In this study, we do a preliminary simulation to find out under what conditions the FCC model encounters constraints on its implementation. The performance of the FCC model will decrease as the number of TV transmitters increase. Otherwise, by looking at the condition of Indonesia, some locations have more than one TV transmitter. Based on simulations, we found the potential method to improve the performance of the FCC model to be applied in the overwhelming areas by the TV transmitters.

The demand on higher data rate in modern communication systems leads to the use of multiband applications. A multiband double layered microstrip antenna is designed for this purpose. The patches are shaped through variation of the widths and lengths of tri-slots to achieve reflection minima at 3.1 GHz, 5.8 GHz, 7.4 GHz and 9.8 GHz, which cover many applications such as WiMAX, Wi-Fi or other wireless applications. The patches are fed by proximity couplings for bandwidth enhancement. The simulation results of the reflection factor are compared by measurements. The measurements verified the theoretical approach.

A multiband double layered microstrip antenna is designed for this purpose. The patches are shaped through variation of the widths and lengths of tri-slots to achieve reflection minima at 3.1 GHz, 5.8 GHz, 7.4 GHz and 9.8 GHz, which cover many applications such as WiMAX, Wi-Fi or other wireless applications. The patches are fed by proximity couplings for bandwidth enhancement. The simulation results of the reflection factor are compared by measurements.
