Kendal, Indonesia: Submarine Cable Landing Point

Kendal is a landing point on the coast of Indonesia, serving as a terminus for submarine cable infrastructure connecting points within the Indonesian archipelago. One submarine cable lands at Kendal, the Jakarta Surabaya Cable System, known by its acronym JAYABAYA. This cable links locations within Indonesia, making Kendal part of a domestic inter-island corridor that supports connectivity along the Java corridor.

Indonesia's submarine cable network spans 70 cables across 139 landing points, and Kendal represents one of the smaller nodes in this broader national infrastructure. With a single cable, Kendal ranks within the top 62 percent of Indonesian landing points by cable count, reflecting that while it is not among the most heavily served locations in the country, it nonetheless participates meaningfully in the national submarine cable graph.

Cables Landing at Kendal

The Jakarta Surabaya Cable System (JAYABAYA) is the sole submarine cable landing at Kendal. Stretching approximately 888 kilometres, this cable reached ready-for-service status in 2018, though its status at that time was noted as draft. The cable connects landing points entirely within Indonesia, serving as a domestic link rather than an international connection. JAYABAYA's routing along the Java coast positions Kendal as one of its intermediate or terminal points within an intra-Indonesian network designed to support connectivity between major population and commercial centres on the island of Java.

Regional Context

Within Indonesia's submarine cable landscape, Kendal hosts considerably fewer cables than the country's leading landing points. Batam leads the country with 20 cables, while Jakarta and Tanjung Pakis each host 9, and Manado, Dumai, and Makassar host 8, 7, and 6 cables respectively. Kendal's single cable places it among the more lightly served of Indonesia's 139 landing points, functioning as a specialised domestic node rather than a major international or regional hub.

Network Role

Kendal operates as a single-cable terminus within Indonesia's submarine cable network, connected exclusively through the JAYABAYA system to other domestic landing points. Its role is specifically oriented toward intra-Indonesian connectivity along the Java corridor, rather than toward international or intercontinental routing. The cable landing here does not establish cross-border links but instead contributes to the internal distribution of submarine capacity within one of the world's most extensive archipelagic cable networks.

In the broader regional submarine cable graph, Kendal's position illustrates how Indonesia's 139 landing points serve a range of functions, from major international hubs like Batam and Jakarta to more focused domestic nodes. The presence of even a single cable at Kendal reflects the scale and geographic complexity of connecting Indonesia's many islands through dedicated submarine infrastructure.
