Banyu Urip: Submarine Cable Landing Point

Banyu Urip is a submarine cable landing point located in Indonesia, a nation whose extensive archipelagic geography has driven the development of a broad submarine cable network. Two submarine cables land at Banyu Urip: the Java-Kalimantan-Sulawesi cable, known as JAKASUSI, and the Jakarta Surabaya Cable System, known as JAYABAYA. Both cables operate entirely within Indonesian waters, making Banyu Urip a domestic connectivity node rather than an international gateway.

The two cables landing at Banyu Urip serve intra-Indonesian corridors, connecting the major islands and population centers that make up the Indonesian archipelago. This positions Banyu Urip as a point of regional, inter-island connectivity within the country's internal submarine cable infrastructure.

Cables Landing at Banyu Urip

The Java-Kalimantan-Sulawesi (JAKASUSI) cable spans approximately 1,100 kilometers and reached ready-for-service status in 2006. As its name suggests, the cable links the Indonesian islands of Java, Kalimantan, and Sulawesi, all of which are endpoints on this system. JAKASUSI represents one of Indonesia's earlier domestic submarine cable deployments, predating many of the country's subsequent intra-island systems.

The Jakarta Surabaya Cable System (JAYABAYA) spans approximately 888 kilometers and reached ready-for-service status in 2018. The cable connects locations within Indonesia, serving the corridor between Jakarta and Surabaya, two of the country's largest urban centers. JAYABAYA's 2018 deployment reflects continued investment in domestic submarine cable infrastructure to support intra-island connectivity across Java and the surrounding region.

Regional Context

Within Indonesia's submarine cable landscape of 70 cables spread across 139 landing points, Banyu Urip sits among a peer group that includes significantly larger hubs such as Batam with 20 cables, Jakarta with 9, Tanjung Pakis with 9, and Manado with 8. With 2 cables, Banyu Urip ranks in the top 85 percent of Indonesian landing points by cable count, reflecting the country's highly distributed cable infrastructure across many smaller nodes.

Network Role

Banyu Urip functions as a domestic, inter-island submarine cable node, terminating two systems that together link key Indonesian islands and cities. JAKASUSI extends the cable corridor northward from Java toward Kalimantan and Sulawesi, while JAYABAYA serves the densely populated Java corridor between Jakarta and Surabaya. Together, these two cables make Banyu Urip a modest but purposeful point within Indonesia's internal connectivity framework.

Rather than serving as a multi-cable international hub, Banyu Urip operates as a focused domestic terminus whose cables address intra-archipelago connectivity. In the broader Indonesian submarine cable graph - where connectivity is distributed across 139 landing points - nodes like Banyu Urip play a role in ensuring that domestic inter-island links extend beyond the country's largest and most heavily served landing points.
