The Effect of Internet Usage on Social Capital in Indonesia
Get PDFThe 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
Expedition Service Product Development Strategy with Quality Function Deployment Method
Get PDFThis 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
Analysis of Microwave Communication Network Planning on Ocean Topography Using Space Diversity
Get PDFOne of the challenges often met by planners of the telecommunications network using microwave radio is surface conditions, especially when passing through the ocean. Propagation conditions above sea surface often result in increasing fading, which significantly affects the reliability of the microwave network. On the other hand, considering that Indonesia is an archipelago, ocean topography is unavoidable, and the use of microwave networks generally considered to be the most efficient among other technologies, especially in Eastern Indonesia. This research aims to respond to such a challenge by planning a microwave communication network using a space diversity technique. The type of microwave network used is a point to point, which links Bali and Lombok islands. The results showed that the use of space diversity techniques could increase fading margins from 34.42 dB to 35.15 dB and availability value from 99.99667% to 99.99873%. Therefore, this technique recommends implementing by telecommunications network providers in accelerating the deployment of connecting networks in areas that have ocean topography
Comparing Mutual Coupling of Ring Metamaterial on Square and Vivaldi Array Antennas
Get PDFThe 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
The Role of Mobile Phone and Internet Use in the Performance of Rural Non-Farm Enterprises: An Analysis of Indonesian Rural Households
Get PDFRural non-farm enterprises have an increasingly important role in economic development in developing countries. The performance of rural non-farm enterprisess is expected to continue to improve in line with the use of telecommunications technology in their business. Such improvement resulted from the use of communication technologies such as mobile phones and internet that are able to reduce information search and expand market information. This study analyzes the role of mobile phone and internet utse in the performance of rural non-farm enterprises. By using household-level data from the Fifth Wave of the Indonesian family life survey (IFLS 5) in 2014 and applying the propensity score matching method, the study found that the use of mobile phones and the internet has a positive impact on the performance of rural non-farm household enterprisess. It shows that the telecommunications infrastructure development policy in rural areas is able to provide economic improvement for rural households
Performance Analysis Of DSDV, AOMDV and ZRP Routing Protocols Application Simulation In Pekanbaru Vehicular Ad Hoc Network (VANET)
Get PDFThe 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
Coded Random Access Technique Based on Repetition Codes for Prioritizing Emergency Communication
Get PDFThis 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
