Gresik, Indonesia

Gresik: Submarine Cable Landing Point

Gresik is a regency located within East Java Province, Indonesia, positioned along the northern coastal zone of Java. Its coastal districts — including Kebomas, Gresik, Manyar, Bungah, and Ujungpangkah — give the regency an extended shoreline presence along the Java Sea, making it a viable location for submarine cable infrastructure. One submarine cable is scheduled to land at Gresik, connecting it to Indonesia's broader domestic cable network.

The single cable landing at Gresik is the Barat Timur Indonesia-1 (BTI-1), a domestic Indonesian system. As its name and endpoint list suggest, this cable is designed to link points within the Indonesian archipelago, enabling intra-national connectivity. With Indonesia comprising over 17,000 islands across a vast maritime expanse, domestic submarine cable systems play a meaningful role in connecting communities and regions that land-based infrastructure cannot easily serve.

Cables Landing at Gresik

The Barat Timur Indonesia-1 (BTI-1) is a domestic submarine cable system with a total length of 4,500 km. It is currently in draft status, with a ready-for-service (RFS) date projected for 2028. All endpoints on this cable are located within Indonesia, making it a purely intra-national system. The cable's name — which translates approximately to "West East Indonesia-1" — reflects its intended function of linking the western and eastern extents of the Indonesian archipelago. Gresik, situated on the northern coast of Java in East Java Province, represents one of the landing points along this route.

Regional Context

Within Indonesia's submarine cable landscape, which spans 70 cables across 139 landing points, Gresik currently hosts one cable and ranks within the top 62% of Indonesian landing points by cable count. Major Indonesian hubs such as Batam (20 cables), Jakarta (9 cables), Tanjung Pakis (9 cables), Manado (8 cables), Dumai (7 cables), and Makassar (6 cables) handle considerably higher volumes of cable traffic, placing Gresik among the smaller landing points in the national network at this stage.

Network Role

Gresik functions as a single-cable terminus rather than a multi-cable hub. Its connection through BTI-1 is oriented entirely toward domestic Indonesian connectivity, supporting the east-west reach of a cable system designed to span the length of the archipelago. With its position on Java's northern coast in East Java Province — adjacent to the broader Surabaya metropolitan area — the landing point at Gresik sits at a geographically significant node within the eastern portion of Java, one of Indonesia's most populous islands.

As BTI-1 moves toward its projected 2028 RFS date, Gresik will contribute to the intra-Indonesian segment of the country's submarine cable graph, reinforcing domestic connectivity along a corridor that runs across one of the world's most geographically complex national territories.
