JaKa2LaDeMa

Overview

JaKa2LaDeMa is a domestic submarine cable system serving Indonesia, connecting ten landing points across the Indonesian archipelago. Spanning approximately 1,700 km, it operates entirely within Indonesian territory, providing intra-national connectivity across several islands. The cable is owned and operated by Telkom Indonesia, the state-controlled telecommunications company.

Route and Landings

All landing points are located in Indonesia. The cable reaches ten coastal stations across the archipelago: Banjarmasin, Beculuk, Denpasar, Gianyar, Ketapang, Mataram, Pankalan, Pontianak, Sangata, and Toweli. These landings span multiple major islands, including Java, Bali, Lombok, Kalimantan, and Sulawesi, linking geographically dispersed population and economic centers through a single submarine system.

Ownership and Operators

JaKa2LaDeMa is wholly owned by Telkom Indonesia. As Indonesia's primary state-owned telecommunications carrier, Telkom Indonesia has developed and operated a range of domestic submarine cable systems to extend connectivity across the country's thousands of islands.

Status and Timeline

The cable entered service in 2010 and has been operational for approximately 16 years. No end-of-service date has been announced.

Regional Context

Indonesia is served by 40 submarine cables landing across 97 points, reflecting the country's dependence on undersea infrastructure to connect its island geography. JaKa2LaDeMa, at 1,700 km, is longer than approximately 64% of the other cables sharing this corridor, placing it in the upper portion of the length distribution despite being a domestic rather than international system.

The regional peers active or planned in this corridor — including Bifrost, Echo, and Apricot, each arriving in 2025, and longer-reach systems such as Asia Connect Cable-1 and Asia United Gateway East — are intercontinental cables many times the length of JaKa2LaDeMa. These systems serve different purposes, connecting Indonesia to international destinations rather than linking domestic landing points. JaKa2LaDeMa's role is distinct: it provides intra-archipelago reach that international cables do not replicate.

Strategic Role

By landing at ten points across Indonesia's main island groups, JaKa2LaDeMa extends domestic submarine connectivity to coastal and island communities that would otherwise rely on satellite links or longer overland routes. Its breadth of landings across Kalimantan, Bali, Lombok, and other regions makes it one of the more distributed domestic cable systems in the Indonesian network, supporting internal data exchange and telecommunications across the archipelago.
