Transformative Sustainable Leadership in Indonesia’s Nusantara Capital City (IKN) Region: A Multi-Case Study of Principals in Core and Buffer Schools

In the vast landscape of educational research, a growing movement seeks to understand how schools can do more than just teach math and reading. Instead, these institutions are being asked to become engines for a better future, helping communities navigate the twin challenges of protecting the environment and building fair, resilient economies. This approach, often called sustainable leadership, suggests that school leaders must guide their institutions to care for people, the planet, and prosperity all at once. For decades, this idea has been tested in stable, well-established countries where change happens slowly. However, the world is also full of places where change is happening at a breakneck pace, often driven by massive new construction projects or rapid urbanization. In these fast-moving environments, the old rules of school leadership may not work. The question becomes: how do school leaders steer their schools through such turbulent times without losing their way, while still teaching students to be good stewards of the earth?

This story takes place in Indonesia, where the government is building an entirely new capital city called Nusantara, or IKN, in the heart of East Kalimantan. This is not just a new set of government buildings; it is a massive experiment in creating a "smart, green, and sustainable" city from scratch. As the city rises, the surrounding region is transforming rapidly. New people are arriving, old landscapes are changing, and the economy is shifting toward green and digital industries. In the middle of this whirlwind are the local high schools. They face a dual challenge: they must keep their students learning well while also preparing them for a future that looks very different from the past. A team of researchers from Mulawarman University decided to watch how the principals of these schools were handling this pressure. They focused on two specific high schools: one located right in the core of the new development zone, where the changes are most intense, and another in a nearby "buffer" zone, where the changes are felt but are slightly less immediate.

The researchers did not simply ask the principals what they thought; they watched what they actually did. They spent time in the schools, listening to conversations, observing how decisions were made, and reading the official plans and reports. They looked for how these leaders used the basic tools of management—planning, organizing, acting, and checking—to build a school culture that could survive and thrive in a changing world. What they found was that these principals were not just following a standard rulebook. Instead, they were weaving together five distinct ways of leading that worked together like a single, complex fabric.

First, these leaders were visionaries. They did not just talk about the environment in vague terms; they created a clear picture of the future that connected their students' lives to the new city. They told a story where learning about renewable energy or digital skills was not just a class assignment, but a way to prepare for the jobs and life that awaited them in the new capital. This vision acted as a compass, guiding every decision the school made.

Second, they realized they could not do it alone. They spread the work of sustainability across the entire school. Instead of the principal being the only person in charge of "green" projects, they formed teams of teachers, students, and parents. They created specific groups for digital learning, for green entrepreneurship, and for character building. This meant that if the principal left, the work would not stop because the responsibility belonged to the whole community, not just one person.

Third, these leaders led by example. They did not just tell students to save energy or respect nature; they showed them how. The principals made sure that the school's daily habits reflected their values, from turning off lights to managing waste. This consistent behavior turned sustainability from a slogan into a normal part of life, a moral standard that everyone in the school understood and followed.

Fourth, and perhaps most importantly for this specific location, these leaders were incredibly adaptable. The new capital city is a place of constant change, with policies shifting and new challenges appearing regularly. The principals learned to adjust their plans quickly. If a new policy came down from the city government, or if a new technology became available, they changed their curriculum and their projects to fit the new reality. They treated change not as a problem to be feared, but as a constant condition to be managed.

Finally, they acted as connectors. They reached out beyond the school gates to build a network of support. They partnered with local government officials, the new city authority, businesses, and community groups. These partnerships were not just for getting extra money; they were essential for making the school's programs real and relevant. By linking the school's goals with the goals of the new city, they ensured that their students were learning skills that the future economy actually needed.

The researchers found that these five patterns—being a visionary, sharing the work, leading by example, adapting quickly, and building networks—were not separate things. In the schools of the new capital, they were all happening at the same time, reinforcing each other. The study suggests that for schools in rapidly changing parts of the world, leadership cannot be static. It must be a mix of holding a steady moral direction while being flexible enough to bend with the wind.

This research offers a new way to think about school leadership in the developing world. It shows that in places where the ground is shifting beneath our feet, the most successful leaders are those who can build a strong, shared vision while remaining ready to pivot at a moment's notice. They are the ones who can turn a school into a living laboratory for the future, where students learn not just from textbooks, but from the very process of building a sustainable city around them. The findings suggest that if other regions are going to face similar rapid transformations, they will need leaders who can master this specific blend of stability and agility, ensuring that education remains a force for good even when everything else is changing.
