Literacy is a legacy that did not simply begin with an understanding of statistical data. Long before that, it developed through the use of symbols and lines that were gradually organized into writing systems, allowing information to be recorded and passed down to generations yet to come. This is the concept we know as aksara, or writing scripts.

At its core, the term aksara originates from Sanskrit (a-kṣara), meaning “indivisible” or “undivided.” From this perspective, every element within a writing system, from symbols and lines to letters that eventually form information and language, serves as a bridge for conveying human thought. In this sense, the idea of being “undivided” reflects how writing has continuously connected the thoughts of individuals across space and time, preserved through written records, whether fictional or nonfictional.

Friends of UNDIRA, long before modern paper came into use, people across the Indonesian archipelago relied on lontar leaves as a writing medium. This material was known for being flexible, durable, and capable of lasting for extended periods. Another traditional writing material was daluang, or dluwang, a form of paper made from processed bark of the saeh tree. It developed across Java, Sunda, and Madura as early as the 9th century.

The evolution of writing materials continued with the use of agarwood bark in several traditional manuscripts, including Pustaha Laklak. It was not until around the 17th century that European paper began to enter the Indonesian archipelago. Its use eventually expanded due to its greater efficiency and compatibility with printing technology.

Beyond the evolution of writing scripts through different media, the development of aksara was also shaped by external influences, particularly cultural exchange and intellectual interaction between different civilizations.

The early development of writing systems in the Indonesian archipelago can be traced back to the arrival of Indian influences around the 4th century, alongside the spread of Hindu-Buddhist teachings. This influence introduced the Pallava script, which later developed into the Kawi script. From around the 8th to the 16th century, Kawi was widely used to record various traditional and historical manuscripts. Evolving from the Buda, or Gunung, script associated with the areas surrounding Mount Merapi and Mount Merbabu, Kawi would later develop into several regional scripts, including Javanese, Balinese, and Sundanese (Cacarakan), while also spreading to Sumatra in the forms of Old Malay and the Incung script.

The next major wave of influence arrived through Arab trade networks, coinciding with the spread of Islam from around the 14th century onward. At the time, the Arabic script was not used solely for copying Qur’anic manuscripts. It was also adapted to represent local languages, giving rise to writing traditions such as Jawi and Malay. Since several sounds and pronunciations found in local languages did not exist in Arabic, communities adapted the script to better accommodate and represent those sounds.

The final major wave came from Europe through trade networks and the arrival of Portuguese and Dutch missionaries in various parts of the archipelago. During this period, Malay, Javanese, and other local languages increasingly transitioned into the Latin script to facilitate administration and education, while also supporting the development of printing systems introduced during the era of the Vereenigde Oostindische Compagnie (VOC).

The Latin script eventually became the last major wave of writing-system evolution to achieve widespread and lasting use. Its development continues to this day through successive improvements to Indonesian spelling conventions, from the Van Ophuijsen Spelling System (1901), the Soewandi Spelling System (1947), and the Enhanced Spelling System (1972), to PUEBI and the current fifth edition of the Enhanced Spelling System.

As we approach National Literacy Day on September 8, 2026, the enduring essence of aksara reminds us that writing is ultimately an extension of human understanding. Through it, ideas, reflections, and human consciousness can be transformed into works that endure across generations, while simultaneously reflecting the development and richness of a civilization, its culture, and its literacy traditions over the course of history.

Preserving aksara, in the end, means preserving the way a nation remembers, understands, and continues to write its own story for generations to come.
