Performance analysis with line-of-sight (LOS) conditions using propagation model urban macro (uMa) according to the recommendation of 3GPP (3rd Generation Partnership Project) TR 38.901. This research based on four scenarios, outdoor-to-outdoor (O2O) for downlink and uplink, and outdoor-to-indoor (O2I) scenario for uplink and downlink. Performance of 5G network simulated using Atoll 3.4 and shown the pathloss values ​​of 105.405 dB for uplink and 101.405 dB for downlink. The performance results in the O2O scenario for the uplink direction require 5 gNodeB and 8 gNodeB in the downlink direction. In the O2I scenario, the uplink direction requires as many as 6 gNodeB and the downlink direction as much as 9 gNodeB. The simulation parameters analyzed in this research are based on the signal strength received by the user (SS-RSRP) and signal quality (SS-SINR). The best result of SS-RSRP in the O2I uplink scenario is -89 dBm and the SS-SINR parameter in the O2O scenario is 0.93 dBm. These results show that in the city of Sawahan a 5G system can be applied.

Abstract

Currently, cellular technology is advancing into the 5G era, which can support data speeds up to 10 Gbps on the uplink side and 20 Gbps on the downlink side. This study aims to plan a 5G NR network by implementing the inter-band carrier aggregation (CA) method. CA is one of the techniques used to achieve high data speeds and to combine two or more radio frequency bands. The primary cell uses band n40 at 2300 MHz with a 40 MHz bandwidth, while the secondary cell uses band n78 at 3500 MHz with a 100 MHz bandwidth. The area that we used for this network design is Agung Podomoro Land (APL) Tower Central Park area in West Jakarta. The propagation model used Urban Macro. Testing process is carried out by comparing the results between using CA and not using CA on the SSRSRP, SS-SINR, and data rate parameters. Simulation results show an average increase in each parameter after the inter-band carrier aggregation method is applied. The SS-RSRP parameter increased by 0.05% with a value of -82.02dBm, the SS-SINR parameter increased by 0.77% with a value of 15.71dB, and the data rate parameter significantly increased by 241.33% with a value of 803.66 Mbps. This proves that implementing the carrier aggregation method can improve the quality and capacity of the network, particularly the data rate, by maximizing the use of the bandwidth and resource block produced by the combination of component carriers.

Abstract

The deployment of 5G networks in provincial capitals such as Semarang presents challenges related to high user demand, coverage requirements, and investment costs. This research aims to evaluate the network coverage and techno-economic feasibility of 5G implementation in Semarang. Using an urban macro propagation model, two scenarios were analysed: Uplink Non-Line-of-Sight (UL-NLOS) and Downlink Non-Line-of-Sight (DL-NLOS). The UL-NLOS scenario requires 11 sites, while the DL-NLOS scenario requires 6 sites to achieve full coverage of the city. The average Synchronization Signal–Reference Signal Received Power (SS-RSRP) is −125.74 dBm, indicating sufficient signal strength. A techno-economic analysis reveals that the UL-NLOS scheme yields an NPV of IDR 292.566.473.678 with an IRR of 110.25%, while the DL-NLOS scheme yields an NPV of IDR 300.000.000.000 with an IRR of 115.38%. These results confirm that both scenarios are technically feasible and economically viable. The findings suggest that 5G deployment in Semarang can yield profitable returns, providing valuable insights for mobile operators in planning future investments.

Abstract

Communication between teachers and parents plays an important role in supporting early childhood education (ECE). However, at Hompimpaa Playschool, the communication medium used in the form of PDF-based liaison books has created several challenges, including time-consuming report preparation, static content, and difficulties in organizing and tracking children’s development records over time. This community service program aimed to assist the implementation of spreadsheets and Looker Studio as a more dynamic, efficient, and accessible digital liaison book. The program was conducted using a participatory mentoring and training approach through three face-to-face sessions, consisting of needs identification, core system training, and implementation assistance with evaluation. Teachers were guided to perform centralized data entry using spreadsheets, while parents were facilitated to monitor children’s development through a Looker Studio dashboard that can be filtered by date. The results indicate a shift in teachers’ workflow from preparing static PDF reports to a simpler and more structured data input process, as well as improved accessibility of information for parents without the need to repeatedly download report files. In addition, a practical user guide module was developed to support program sustainability. This activity demonstrates that the application of simple digital technologies, when accompanied by proper mentoring, can enhance teacher–parent communication, reduce teachers’ administrative workload, and has the potential to be replicated in other early childhood education institutions facing similar challenges.

Abstract

The development of telecommunications technology in Indonesia is driving the increased demand for high-speed data services, one of which is through the implementation of 5G networks. The Indonesian government has established the use of the low band 700 MHz frequency band, which is adjacent to the digital television service frequency DVB-T2, specifically 478–694 MHz. This condition has the potential to cause interference between systems. This study analyzes the probability of interference between 5G services and DVB-T2 using SEAMCAT based on the Monte Carlo (MC) method with the Okumura-Hata propagation model. The simulation results show that the farther the distance between the transmitter and the DVB-T2 receiver, the lower the probability of interference tends to be. At a transmission power of 30 dBm, a minimum distance of 10 km is required to reduce the probability of interference to 1%. Additionally, higher transmission power increases the risk of interference, especially at close distances. Therefore, appropriate frequency management strategies and power level determination must be implemented to optimize the 5G rollout without disrupting DVB-T2 services, especially in areas with high transmitter density.

Abstract

The widespread change from analog to digital television broadcasting in Indonesia has led to the emergence of blank spots in some areas. To overcome this problem, an optimal propagation model is needed to improve transmitter coverage, energy efficiency, and field strength through optimal transmit power for DVB-T2 broadcasts. This research addresses the selection and analysis of an appropriate propagation model, focusing on the application of the Longley-Rice and ITU-R.P 1546-6 models in the Kebumen region of Central Java, Indonesia. This study specifically compares the two models to determine the most effective model in reducing blank spots in the area. The results show that the Longley-Rice model produces greater field strength than the ITU-R.P 1546-6 model. In addition, this study also found that the farther the receiver is from the transmitter, the higher the free space loss value. This is because due to the hilly geographical conditions in the Kebumen area, it causes high loss. And the farther the receiver is from the transmitter and the greater the frequency value, the greater the field strength value. This research not only provides relevant empirical data for the Kebumen region but also offers insights that can be used in the optimization of digital broadcasting in other urban environments in the future.

Abstract

This community engagement program aims to support the implementation of a digital-based selection system for village apparatuses, specifically in the selection of hamlet heads (Kepala Dusun) in Karanggintung Village, Banyumas Regency. The process was carried out through a partnership between Telkom University Purwokerto and the village government, utilizing a Computer Assisted Test (CAT) system based on the Moodle Learning Management System (LMS). The activity covered the full cycle from technical setup, simulation, question input, to the digital exam execution for 16 candidates. The system successfully ensured transparency and objectivity through automatic scoring and real-time ranking. However, none of the participants achieved the minimum passing grade of 65, highlighting the gap between digital assessment standards and participant readiness. Despite the zero-passing result, participant satisfaction remained high, with most expressing strong agreement on the effectiveness of the process. This indicates public acceptance of digital mechanisms when implemented transparently and professionally. The case offers important insights into the intersection of digital governance, rural capacity, and democratic values at the local level.
