Superhub development is crucial for enhancing the economic prowess and sustainability of a region, focusing on bolstering its global competitiveness and amplifying its impact on national and regional growth. In the case of Nusantara, Indonesia’s new capital city, understanding public sentiment towards its development plan is essential. This study employed sentiment analysis, combining a comprehensive dataset of 433,637 tweets from 2020 with public documents and machine-learning tools to accurately gauge public opinion. Six key components of regional development emerged from the analysis, reflecting public discourse on IKN’s planning and execution. Geographically, sentiment across the 33 provinces was evenly distributed, with 63% positive, 24% negative, and 13% neutral sentiments observed in the tweets. However, sentiment fluctuated throughout the year, with a surge in negative sentiment early in 2020 due to concerns over financing risks and economic challenges. Nonetheless, negativity waned as the year progressed, with positive tweets steadily increasing from April to December. These findings offer valuable insights for guiding the development of Nusantara, aiding policymakers in addressing public concerns, and ensuring a more informed and inclusive approach. Such sentiment analysis proves instrumental in shaping the strategic trajectory of the new capital city, fostering sustainable growth and public support. Keywords.

Pengembangan superhub sangat penting untuk meningkatkan kekuatan ekonomi dan keberlanjutan suatu wilayah, dengan fokus pada peningkatan daya saing global dan memperkuat dampaknya terhadap pertumbuhan nasional dan regional. Dalam kasus Nusantara, ibu kota baru Indonesia, memahami sentimen masyarakat terhadap rencana pembangunannya sangatlah penting. Studi ini menggunakan analisis sentimen, yang menggabungkan kumpulan data komprehensif 433.637 tweet dari tahun 2020 dengan dokumen publik dan alat pembelajaran mesin untuk mengukur opini publik secara akurat. Enam komponen kunci pembangunan daerah muncul dari analisis tersebut, yang mencerminkan wacana publik mengenai perencanaan dan pelaksanaan IKN. Secara geografis, sentimen di 33 provinsi tersebar secara merata, dengan 63% sentimen positif, 24% negatif, dan 13% netral terlihat dalam cuitan tersebut. Namun, sentimen berfluktuasi sepanjang tahun, dengan lonjakan sentimen negatif di awal tahun 2020 karena kekhawatiran terhadap risiko pembiayaan dan tantangan perekonomian. Meskipun demikian, hal-hal negatif semakin berkurang seiring berjalannya tahun, dengan tweet positif yang terus meningkat dari bulan April hingga Desember.
