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.","PeriodicalId":30954,"journal":{"name":"Buletin Pos dan Telekomunikasi Media Komunikasi Ilmiah","volume":"588 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72400560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":30954,"journal":{"name":"Buletin Pos dan Telekomunikasi Media Komunikasi Ilmiah","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78664570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 2018 data obtained from the Riau Province Revenue Agency indicated that the total number of 4-wheeled vehicles registered in the Pekanbaru city is 181,748. This high number of vehicles causes several traffic problems, such as increased number of accidents and congestion. Therefore, it is necessary to develop a communication technology capable of providing vehicle traffic information such as the Vehicular Ad Hoc Network (VANET). Over the last few years, various wireless technological devices that provide communication between vehicles have been developed. VANET is one of such technologies developed with Mobile Ad Hoc Network (MANET) for vehicles to communicate with each other (Pradana et al., 2017). This device enables each car to receive information related to traffic conditions and travel conditions, using nodes, which form an Ad hoc network called the Vehicular Ad hoc Network (VANET) (Dimyati et al., 2016). The fundamental objective of this research on VANET is to develop a vehicle communication system that allows fast and efficient data exchange that is used as an intelligent traffic information system (Pradana et al., 2017). Although VANET is very helpful for traffic information systems, the construction of VANET systems infrastructure is not easy because it requires high cost in its development and testing. In order that research on VANET can be continued, VANET network modeling is carried out in the form of simulation (Nutrihadi, 2016). The advantage of doing the simulation beforehand is the flexibility to model and evaluate the design without building a physical network. The simulation results are expected to provide the foundations to allow the actual implementation of the technology in Indonesia, especially in Pekanbaru. VANET has a routing protocol that functions to determine the route according to its characteristics. According to Virgono and Yovita (2016) routing protocols are very influential on network performance and Buletin Pos dan Telekomunikasi Vol. 18 No.2 (2020): 127-144 128 are used to face challenges related to dynamic network topology. This study is conducted to simulate the maximum performance comparison of proactive, reactive and hybrid types of DSDV, AOMDV, and ZRP routing protocols. Data is collected through direct method by counting the number of vehicles passing several protocol roads. The obtained data are simulated on software with variations in the transmission distance range to improve the reliability of the routing path used and create a more extended connection between vehicles. The scenario is carried out in conditions of network changes and breakneck node speeds. The VANET network provides driving safety information, so a fast and efficient routing protocol is needed. VANET Network performance is measured by the Quality of Service (QoS) parameter, because QoS describes the measurement of the ability of a network to achieve maximum performance determined by parameters such as end-to-end dela","PeriodicalId":30954,"journal":{"name":"Buletin Pos dan Telekomunikasi Media Komunikasi Ilmiah","volume":"68 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74009816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":30954,"journal":{"name":"Buletin Pos dan Telekomunikasi Media Komunikasi Ilmiah","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91057734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study shows that increase in the use of non-GSO satellites is caused by the growth in remote sensing application, M2M application, and development of LAPAN’s satellites. In the future, the growth of non-GSO remote sensing satellite is predicted to be caused by the same reason. The increase in the use of non-GSO telecommunication satellites, however, will be affected more by the new global trend.
