Abstract

Segmentasi adalah salah satu metode yang penting untuk mengubah citra input menjadi citra output berdasarkan atribut yang diambil dari citra tersebut. Segmentasi citra membagi citra ke dalam daerah intensitas masing-masing sehingga bisa membedakan antara objek dengan background-nya. Ada banyak metode untuk segmentasi citra salah satunya adalah homotopy tree.Homotopy Tree adalah metode yang membagi objek berdasarkan kesamaan topologi dengan menggunakan struktur seperti pohon, terdapat akar (root), node dan bercabang. Kesamaan topologi pada homotopy tree diperoleh dengan melakukan klasifikasi derajat keabuan pada suatu citra, kemudian itu mengidentifikasi nilai piksel dan mengklasifikasikannya.Dalam aplikasi ini objek yang digunakan adalah hasil dari pembuatan dengan menggunakan Aplikasi Desain Grafis, yaitu software CorelDraw X7. Pengenalan objek dengan menggunakan metode homotopy tree ini dilakukan dengan cara input citra dalam bentuk RGB, setelah itu diproses menjadi grayscale kemudian di segmentasi dengan mengenali nilai piksel- piksel dari objek tersebut, hasilnya dalam mengenali objek cukup bagus, dan terbentuk tree dengan baik.

Abstract

Background Telecommunication accessibility is a key driver of inclusive development, particularly in Indonesia’s 3T (Disadvantaged, Frontier, and Outermost) regions, where geographical isolation and infrastructure limitations constrain economic opportunities. To reduce the digital divide, the Indonesian government has prioritized national programs such as the Palapa Ring and the deployment of Base Transceiver Stations (BTSs). This study examines how these initiatives influence telecommunication accessibility and local economic dynamics in East Nusa Tenggara (NTT). Methods This study employed a qualitative case study approach. Data were collected through in-depth interviews with local government officials, telecommunication providers, community leaders, and end users, complemented by field observations and document analysis. The data were analyzed thematically to identify access conditions, structural challenges, and local economic responses to telecommunication development. Results The findings indicate that expanding fiber-optic networks and BTS infrastructure has improved basic connectivity and reduced isolation in several 3T areas. Improved access supports micro, small, and medium enterprise activities, enhances access to digital education, and enables emerging digital-based livelihoods. However, benefits remain uneven due to persistent last-mile connectivity gaps, unstable network quality, low digital literacy, and limited affordability. Conclusions Telecommunication infrastructure development in 3T regions is necessary but insufficient for inclusive local economic growth. Integrating infrastructure expansion with digital literacy programs, affordability support, and targeted last-mile interventions is essential to maximize socio-economic benefits.
