One coastline, two centers, sorted by the numbers.

East Lampung Regency’s Jabung sub-region and its coastal strip span twelve kecamatan, from inland agricultural land to fishing ports on the Java Sea. The regency wanted two development models running at once (agropolitan zoning inland, minapolitan zoning along the coast), but pursuing both everywhere at once would have meant no real center for either. That is the same problem of sorting many sub-units by underlying capacity rather than administrative label that runs through the Cikarang industrial-settlement study.

The regency’s existing spatial plan (RTRW 2011–2031) already classifies each kecamatan as a Pusat Kegiatan Lokal, Promosi, Kawasan, or Lingkungan center: a policy label, not a ranking. Deciding which sub-districts had the underlying capacity to anchor real growth needed a method that scored them against each other, not just against an administrative category.

The actual method scores each kecamatan against 19 facility and service indicators, weights them, and produces a Skalogram hierarchy score. The higher the score, the more developed the sub-district’s service base, and the stronger its case to anchor growth rather than depend on a neighboring center. Nineteen is also the exact indicator count behind the P3KE characteristic clustering in Kalimantan Timur’s poverty mapping, a coincidence of scope, not method, but the same instinct to score against many indicators at once rather than one proxy variable.

Way Jepara lands at Hierarki 1 with an IPD score of 32.73 and 13 of 19 facility types present, the strongest service base in the study area. Labuhan Maringgai, at Hierarki 2, actually carries more facility types (17 of 19) and a strategic coastal position, making both kecamatan candidates should Lampung Timur ever split into a new regency.

Sorting all twelve kecamatan by their Skalogram hierarchy produces a clear shape: Way Jepara alone as the main growth pole, four kecamatan (Labuhan Maringgai, Sekampung Udik, Pasir Sakti, Mataram Baru) as secondary centers, and the remaining seven classified as hinterland, areas the plan supports rather than expects to lead.

Bandar Sribhawono (corn, cassava, rice, rubber, and palm oil, sitting on the province’s Feeder Road corridor) anchors the Agropolitan zone. Labuhan Maringgai and Pasir Sakti, with three working fishing ports and a growing crab-processing trade, anchor Minapolitan, a working coastline not unlike the fishing boats further south on Lampung’s Tanggamus coast. Neither label was applied uniformly across the coastline: each traces back to a specific kecamatan’s Skalogram profile.

The plan carries three delivery scenarios: optimistic (100% of planned area and infrastructure development realized), moderate (80%), and pessimistic (50%), each tied directly to whether economic growth, the human development index, and infrastructure provisioning hit, undershoot, or badly miss the plan’s targets. The hierarchy and zoning are fixed; how much of them materializes isn’t.
