Abstract—Indonesia is the fourth-most populous country, with 260 million people. This increases telecom network demand. 4G-LTE is Indonesia's lea ding mobile technology (LTE), but its network is now crowded. The telecom business must adjust to consumer mobility and growing demand. The Indonesian government urges the deployment of 5G New Radio (NR) with Non-Stand Alone (NSA) model in 13 Indonesian cities area, especially in the capital city of Jakarta, which is the economic and government center of Indonesia. This research attempts to determine the technological and economic plans needed to satisfy the 5G NR mid-band 3.5 GHz with the NSA model for both capacity and coverage needs in a metropolitan and denseurban area of Indonesia, Jakarta City. This research utilized mid-band 3.5 GHz frequency due to its ability to hold optimum capacity and coverage, especially for greenfield operator scenarios (new mobile operators). According to analysis, all Jakarta municipals will need 919 5G NR 3.5 GHz gNodeB and create 17.7 Gbps/km² of traffic. Synchronization Signal-Reference Signal Received Power (SS-RSRP) averages -93.27 dBm and is rated good, while SS-SINR averages 8.89 dB and is considered fair. In terms of economics, total CAPEX is IDR 147,184,134,855, total OPEX is IDR 1,004,463,403,900, Net Present Value (NPV) is IDR 477,532,953,385, Internal Rate of Return (IRR) is 24.7%, Payback Period (PBP) is 3.87 or within three years and ten months, and Profitability Index (PI) is 1.42. Meanwhile, the results of the sensitivity analysis indicates that the number of gNodeB and the number of users are the most significant parameters that greatly affect the business feasibility of deploying 5G NR NSA with 3.5 GHz in the metropolitan area of Jakarta City.
