Abstract

The antenna performance is seen from the S-parameter value. The S-parameter graph can be seen as the return loss (S11, S22) and the mutual coupling (S21, S12) value. This research focuses on analyzing mutual coupling on Square and Vivaldi array antennas using the ring metamaterial method. The value of mutual coupling is considered very important to analyze because it affects the performance of the antenna in which is arranged in an array. The simulation results of the mutual coupling value obtained on a square array antenna use a ring metamaterial is -17 dB at a frequency of 2.4 GHz. Meanwhile, the Vivaldi array antenna uses a ring metamaterial that produces a mutual coupling value of -13.840744 dB at a frequency of 3.0162 GHz. The factors that affect the square array antenna so that it becomes the best to suppress the mutual coupling value between antenna elements are a selection of metamaterial shape and proper placement between the antenna array elements is arranged horizontally.

Abstract

This research uses repetition codes based on Coded Random Access (CRA) to support Internet of Things (IoT) to give priority to emergency commutations in super-dense networks. Degree distribution for emergency group and general group are obtained with extrinsic information transfer (EXIT) analysis to achieve small error performance shown by the very small gap between emergency group curve and general group curve. This research also evaluates performance by observing throughput and packet-loss rate (PLR) parameters from every groups. Offered traffic in PLR  for emergency group user is G= 0,7 packet/slot without fading and G= 0,65 packet/slot with fading, while for public group is G=0,699 packet/slot without fading and G=0,42 packet/slot with fading. Peak throughput for emergency group is G= 0,737 packet/slot without fading and G= 0,729 packet/slot with fading. Peak Throughput for public group is G= 0,699 packet/slot without fading and G=0,685 packet/slot with fading. Throughput values of emergency group are higher than those of the general group, indicating successful process of giving priority for emergency group.

Abstract

The need for LPWA-based Internet of Things (IoT) technology for deploying smart metering services is rapidly growing for its ability to manage energy usage in real-time and increase efficiency. However, the problem faced by electric utility companies is how to choose the most appropriate technology. This study uses a techno-economic approach to compare the two most widely used technological alternatives, namely establishing LoRaWAN as a non-licensed LPWA technology or leasing NB-IoT as a licensed LPWA technology owned by a telecommunications operator. Case studies conducted in the urban area of Bandung and sub-urban city of Tasikmalaya as an example of a typical town in Indonesia. The results showed that LoRaWAN and NB-IoT are both technically and business feasible to be implemented with their respective advantages. LoRaWAN is superior in battery lifetime, business model, speed of implementation, and total costs, whereas NB-IoT is superior in range, capacity, quality of service, security, and ecosystem support. Using PLN's perspective as a national electricity company in Indonesia, LoRaWAN has a Net Present Value of 23% higher than NB-IoT in the 10th year.

Abstract

This study assesses the quality of Express Post service provided by PT. Pos Indonesia with Quality Function Deployment Method (QFD). Approximately 90 customers of Express Post in Boyolali were selected through systematic sampling to gather their opinions. In the meantime, PT Post Indonesia’s Jakarta Central Office’s Research and Development Department is involved to collect technical responses or activites. This study has identified 12 attributes of Express Post that require improvement. To solve the problems related to those attributes, this study has identified training on Express Post service standard operating procedure for new employees as the priority activity to be undertaken by PT. Pos Indonesia since it has the most significant influence on the quality of Express Post. In addition, the study also suggests two other technical responses to be taken into consideration including ensuring service cut of time of and ensuring delivery reception not disrupting the service cut off time.

Abstract

The increase in the number of vehicles without the development of driving safety technology, tends to create adverse impacts on society, such as a rise in casualties due to road accidents. Therefore, vehicles need information on the condition of the surrounding traffic environment to provide driver with safety. One of the methods used to obtain prompt information between vehicles that move dynamically is communication technology such as Vehicular Ad hoc Network (VANET). VANET has network characteristics that change rapidly due to the highly dynamic node movement. Therefore, it is necessary to choose the right routing protocol for optimal data transmission. In this study, the DSDV (Destination Sequenced Distance Vector), AOMDV (Ad-hoc on Demand Multipath Distance Vector), and ZRP (Zone Routing Protocol) routing protocols were tested using 3 field data scenarios. The first scenario is a variation of the number of nodes 100, 250, 600, and 700 nodes. The second scenario is a variation of the transmission ranges of 250m, 500m, and 1km. The third scenario is the variation of node speeds of 10 km/hour, 20 km/hour, 30 km/hour, 40 km/hour, and 50 km/hour in Pekanbaru city of Riau province. This research was carried out using the simulation method along with the QoS (Quality of Service) performance testing parameters comprising packet delivery ratio, end to end delay, throughput, collision rate, and packet loss. Out of the three scenarios tested, AOMDV is the best routing protocol to be implemented because it outperforms the other two protocol evaluated in all designated scenarios in the paper. Meanwhile, DSDV and ZRP are superior in end to end delay and routing overhead parameters, respectively.

Abstract

The 4G LTE network has been launched in many countries including Indonesia, and all telecommunications operators are competing to expand their service coverage. Due to various reasons, there are a lot of areas that remains uncovered by the 4G LTE network. With the increase in cellular traffic, operators must continue to improve their service coverage. One of the scenarios to expand the service coverage is by offloading the traffic to a more cost-effective 802.11ah network in which one 802.11ah access point can serve thousands of mobile devices and support the Machine-to-Machine (M2M)/Internet of Things (IoT) communication. This study simulates the effect of the number of nodes on MCS performance evaluation of the 802.11ah protocol. The simulation is conducted by utilizing NS3 software to evaluate the throughput, delay, packet delivery ratio and energy consumption. This study also simulates 802.11ah coverage prediction to expand the LTE networks by utilizing Atoll Radio Planning Software. The results show that the performance obtained by varying the number of nodes/users from 100 to 1000 nodes is technically acceptable. In addition, the service coverage of 802.11ah network can solve the problem of blank spot area.

Abstract

The development capital consists of financial capital, physical capital, human capital, and social capital. Social capital focuses on efforts to empower social relations. The relationship between social capital and ICT, especially the internet, has become an interesting debate. In fact, several studies have been conducted with quite diverse findings. The internet is able to connect people who are far from each other, but on the other hand, it often makes people who are physically close to each other seem far apart. This study aims to examine the effect of internet use on social capital in Indonesia. The data is obtained from the fifth Indonesian Family Life Survey (IFLS-5). The study found that in general, internet users have lower social capital than non-internet users. Likewise, highly educated people have higher social capital than people with low education. Then, internet users with higher education have higher social capital when compared to internet users with lower education. This means that the use of the internet must be accompanied by the readiness of human resources (digital literacy) in accepting new technology, filtering the flow of incoming information, and educating the public about how to use the internet in healthy, safe, and wise manner.
