Source: GoodStats Data summaries of the BPS Construction Cost Index 2026 publication for West Java (17 October 2026) and East Java (18 October 2026); the East Java provincial IKK of 99.28 from the GoodStats summary; the BPS publication page for the definition and reference city. homeX calculation: Bogor Regency 130.33 versus Gresik 111.23 is about 17.17% higher; Bogor Regency versus Jombang 103.34 about 26.12%; Gresik versus Jombang about 7.63%. Data gaps: we do not have the West Java provincial IKK; ranks below the top 10; Medan itself; prior-year figures; or a machine-readable official BPS table (figures are quoted from GoodStats). The GoodStats summaries contain typos, e.g. "year 2016" for Bandung Regency and "IKIP" for Jombang; we read them as IKK 2026 and Jombang 103.34, to be checked against the BPS publication. The BPS page shows a publication date of 2 October 2026 while the page metadata says 1 October 2026. IKK is not a material price; the gap column is not official data.

Patterns across the two provinces

In West Java, the Bogor-Bekasi-Depok area, Bandung and Karawang dominate the list: Bogor Regency, Bogor City, Bekasi City, Cimahi, Bekasi Regency, Karawang and Depok. In East Java, the gaps between areas are narrower (103.34 to 111.23) and Gresik, Surabaya and Sidoarjo sit in the Surabaya industrial corridor. homeX analysis, not data: the pattern is consistent with higher construction cost in dense and industrial areas, but the source does not explain the cause.

How to use IKK for a renovation or house-building budget

IKK is an index relative to Medan, not rupiah per square metre. A safe approach: take cost per m2 from a local quote or the homeX house-building cost articles, then use the IKK ratio only to compare two locations, noting that the IKK weights cover buildings, roads and networks. Also compare with the homeX national IKK 2026 article for the 10 highest and lowest provinces.

Buyer tips

Use IKK to compare locations, not to calculate rupiah per m2.
Get local quotes as the budget base, then compare with IKK.
Check quoted figures in the original BPS publication before using them in official documents.
Watch material freight to remote areas even if the nearest city has a lower IKK.
