The Sea as a Medium for Energy Security: Reflections for Indonesia


In today’s global landscape, the sea is increasingly recognised not merely as a geographical space, but as a strategic domain for energy security.

Global dependence on maritime routes for the movement of energy commodities—particularly oil and gas—means that the stability of sea lanes has become closely linked to economic resilience, geopolitical stability, and international security.

Developments around major maritime chokepoints, including the Strait of Hormuz, illustrate how disruption in one part of the maritime system can have consequences far beyond the immediate region. A disturbance at sea can affect shipping, energy prices, supply chains, and the wider global economy.

From this perspective, the sea is more than a transport corridor.

It is part of an interconnected system linking energy, security, trade, geopolitics, and governance.

For Indonesia, this has particular significance.

As the world’s largest archipelagic state, Indonesia occupies a strategic position within regional and global maritime connectivity. Important sea lanes pass through and around the Indonesian archipelago, including the Strait of Malacca, Sunda Strait, and Lombok Strait.

This position creates opportunities, but it also brings responsibilities.

Maintaining safe, stable, and well-governed maritime spaces is important not only for Indonesia’s national interests, but also for the wider regional system that depends on these routes.

At the same time, Indonesia’s relationship with energy and the sea extends beyond maritime transport.

Indonesia’s marine and coastal spaces also contain energy potential of their own. Alongside offshore oil and gas resources, emerging marine renewable energy technologies—including tidal, wave, current, and other ocean-based energy systems—offer possibilities for diversifying the country’s future energy landscape.

This creates an important strategic question:

Can Indonesia move from seeing the sea primarily as a route through which energy passes, towards understanding it as part of a broader national energy system?

Through the perspective of the Blue Maritime Mindset (BMM), CitaNesia views energy security as inseparable from the way society understands the sea.

The sea should not be viewed only as infrastructure, territory, or a source of commodities.

It can also be understood as an integrated maritime space in which security, sustainability, economic resilience, environmental responsibility, and national identity intersect.

Such a perspective encourages Indonesia to think beyond the role of a passive user of global maritime routes.

Indonesia has the potential to strengthen its role as a maritime actor capable of governing, safeguarding, and strategically developing its marine spaces as part of a changing regional and global energy system.

This does not mean that maritime energy development should be pursued without limits.

Energy security and maritime development must also be considered alongside ecosystem protection, coastal communities, technological capacity, governance, and long-term sustainability.

The future of energy at sea is therefore not only a technological or economic question.

It is also a question of how Indonesia chooses to understand, govern, and value its maritime space.

CitaNesia Insight

A maritime mindset allows us to see that energy security does not begin and end with ships carrying fuel across the ocean.

It also involves the resilience of sea lanes, the governance of strategic waters, the sustainability of marine resources, and the capacity to develop future energy systems responsibly.

For an archipelagic country such as Indonesia, the sea is not simply where energy moves.

It can also become part of how energy security is imagined, governed, and strengthened.

Further exploration of this topic will continue through future KristaNesia publications as part of CitaNesia’s contribution to strengthening Indonesia’s strategic maritime thinking.

Serial Punggawa Laut Episode 3: Hang Tuah

The Admiral Who Connected Kingdoms Across the Sea

This image is a creative illustration for storytelling and educational purposes.

Hello, Friends of Cita & Nesia!

Long ago, around the fifteenth century, there was a powerful maritime kingdom called Melaka.

Its port was busy.

Ships arrived from many places.

Traders brought spices, textiles, ceramics, knowledge, languages, and stories.

The sea around Melaka was not empty space.

It was a great highway connecting people across the region.

And in this busy maritime world lived one of the most legendary figures of the Nusantara.

His name was Hang Tuah.

A Young Man with Courage and Intelligence

Stories about Hang Tuah describe him as brave, clever, disciplined, and deeply loyal.

He was known not only as a skilled fighter, but also as someone trusted by the ruler of Melaka.

As his responsibilities grew, Hang Tuah became associated with the role of laksamana, or admiral.

But being an admiral was not only about fighting battles.

Hang Tuah also travelled as a royal envoy.

That meant he represented Melaka when meeting people from other kingdoms.

Imagine that.

He had to understand how to speak carefully.

He had to know how to behave.

He had to protect the dignity of his kingdom.

And he had to build trust with people from faraway places.

This makes Hang Tuah more than a warrior.

He can also be remembered as a maritime diplomat.

The Sea as a Bridge

When we think about the sea, we sometimes imagine distance.

One island is here.

Another kingdom is far away.

Between them is water.

But for maritime communities, the sea can also do the opposite.

It can bring people together.

Ships carried goods.

Sailors carried knowledge.

Diplomats carried messages.

And travellers carried stories from one society to another.

Hang Tuah lived in this connected world.

His journeys remind us that the sea was not only a place for conflict.

It was also a bridge of civilisation.

Through maritime routes, kingdoms could trade, negotiate, exchange ideas, and learn about one another.

What Makes a Good Maritime Leader?

Imagine that you are asked to represent your community in another country.

What would you need?

Strength?

Perhaps.

But strength alone would not be enough.

You would also need:

Courage — to travel into unfamiliar places.

Wisdom — to know when to speak and when to listen.

Responsibility — because your actions may affect other people.

Trustworthiness — because others need to believe your word.

These qualities help us understand why stories about Hang Tuah have lasted for generations.

He represents an idea of leadership that reaches beyond physical strength.

A maritime leader may need to defend.

But a maritime leader may also need to communicate.

To negotiate.

To understand differences.

And to create relationships.

The Question of Loyalty

One value especially associated with Hang Tuah is loyalty.

Many stories describe his devotion to the Sultan of Melaka and to the kingdom he served.

There is also a famous phrase often associated with his story:

“Takkan Melayu hilang di bumi.”

It is commonly understood as an expression of confidence that Malay identity and culture will endure.

Over generations, Hang Tuah has therefore become more than a historical or literary character.

He has become part of wider conversations about loyalty, identity, leadership, and belonging.

But his story also gives us something interesting to think about.

What does it mean to be loyal?

Does loyalty simply mean following someone?

Or should loyalty also include responsibility, wisdom, and concern for the community?

These are questions that make the story of Hang Tuah continue to be discussed today.

A Maritime World Built Through Relationships

Melaka became important partly because of its position along major maritime trade routes.

But geography alone does not create a successful maritime centre.

People must also be able to cooperate.

Merchants need trust.

Leaders need diplomacy.

Communities need rules.

Visitors need places where they can communicate and exchange goods safely.

Hang Tuah’s story helps us imagine this broader maritime world.

A world in which ships connected ports, but relationships connected people.

CitaNesia Insight

Hang Tuah reminds us that a maritime mindset is not only about protecting the sea.

It is also about understanding connection.

The sea can connect different islands.

It can connect different languages.

It can connect different cultures.

And it can connect different kingdoms.

A strong maritime leader therefore needs more than courage.

They also need the ability to build relationships across differences.

Through the story of Hang Tuah, we can see three important maritime values:

Loyalty — understanding what and whom we are responsible for.

Diplomacy — building relationships through communication rather than conflict alone.

Identity — knowing where we come from while still engaging with a wider world.

Perhaps this is one of the most important lessons from the maritime history of Melaka:

The sea does not only separate people. It can teach people how to meet.

A Little Question for KawanCita

Imagine you meet someone from a place very different from your own.

They speak differently.

They eat different foods.

They have different traditions.

Would those differences stop you from becoming friends?

Or could curiosity help you understand each other?

Hang Tuah’s maritime world reminds us that travelling across the sea often meant encountering people who were different.

Learning how to communicate across those differences was part of maritime life.

And perhaps that is still an important maritime mindset today:

Know who you are, but remain curious about the world beyond your shore.

Serial Punggawa Laut Episode 2: Cut Nyak Malahayati

The Admiral Who Turned Courage into Strength

This image is a creative illustration for storytelling and educational purposes

Hello, Friends of Cita & Nesia!

Let us travel to the western edge of the Nusantara.

There, in Aceh, the land meets the wide Indian Ocean.

For hundreds of years, ships travelled through these waters. Traders, sailors, travellers, and powerful kingdoms crossed the sea, making Aceh an important part of the maritime world.

And from this maritime land came one of the most remarkable women in Indonesian history.

Her name was Cut Nyak Keumalahayati, better known as Laksamana Malahayati.

She was a woman who did not simply live beside the sea.

She became a leader upon it.

When the Sea Became a Place of Courage

During Malahayati’s time, in the late sixteenth century, the Sultanate of Aceh was an important maritime power.

Its position near major sea routes brought opportunity.

But it also brought danger.

Foreign ships arrived in the region, and competition over trade and influence could sometimes lead to conflict.

Malahayati lived within this challenging maritime world.

She had also experienced personal loss.

Her husband, who was also a military figure, died in battle.

Imagine how difficult that must have been.

She could have stepped away.

She could have allowed grief to stop her.

But Malahayati chose another path.

She turned loss into courage.

The Women of Inong Balee

Malahayati became associated with a remarkable group known as the Inong Balee.

In Acehnese, inong balee refers to widowed women.

Many of these women had lost their husbands in conflict.

But their stories did not end there.

They came together.

They trained.

They learned to defend their homeland.

And under Malahayati’s leadership, they became part of Aceh’s maritime defence.

The Inong Balee were not simply remembered because they were women.

They were remembered because they demonstrated something powerful:

People who experience loss can still find strength through solidarity.

Instead of facing their grief alone, these women became part of a community with a shared purpose.

Malahayati and the Ships from Far Away

One of the best-known stories about Malahayati concerns the arrival of Dutch ships commanded by Cornelis de Houtman.

In 1599, tensions between the Dutch expedition and Aceh developed into armed conflict.

Malahayati and Acehnese forces confronted them.

Historical accounts associate Malahayati closely with the conflict in which Cornelis de Houtman was killed.

Over generations, the story has often been told as a dramatic encounter in which Malahayati herself defeated him.

Whether every detail of the famous story can be reconstructed with certainty today, its place in Indonesian maritime memory is powerful.

Malahayati became remembered as a woman who stood at the centre of maritime leadership during a difficult period in Aceh’s history.

And that alone makes her extraordinary.

Can a Woman Lead at Sea?

Imagine being a child living hundreds of years ago.

Perhaps you had been told that certain jobs belonged only to men.

Then imagine seeing Malahayati.

A woman giving commands.

A woman organising maritime defence.

A woman leading people.

A woman standing in one of the most demanding spaces of her time.

The sea did not ask whether she was a man or a woman.

Leadership depended on something else:

knowledge, courage, responsibility, and the ability to bring people together.

Malahayati’s story reminds us that maritime history was not created only by kings, male sailors, explorers, and soldiers.

Women were there too.

They led.

They organised.

They protected communities.

And they helped shape the maritime history of the Nusantara.

Strength Does Not Mean Having No Sadness

There is another lesson in Malahayati’s story.

Sometimes we imagine courageous people as people who never feel afraid, sad, or hurt.

But courage does not necessarily mean living without those feelings.

Malahayati experienced loss.

The women of Inong Balee experienced loss too.

Their strength did not come from pretending that nothing painful had happened.

It came from continuing to move forward.

Together.

That is a different kind of strength.

What Does Malahayati Teach Us About Maritime Mindset?

When we hear the words maritime strength, we might immediately imagine:

big ships,

powerful fleets,

weapons,

ports,

or naval forces.

But CitaNesia invites us to look deeper.

Behind every ship are people.

Behind every maritime community are relationships.

And behind strong relationships are values.

Malahayati’s story highlights three of them:

Courage — facing difficult situations even when we are afraid.

Solidarity — standing together rather than facing challenges alone.

Dignity — understanding that people and communities have something worth protecting.

These values can also form part of a maritime mindset.

CitaNesia Insight

Laksamana Malahayati reminds us that a maritime mindset is not only about knowing how to sail or understanding the ocean.

It can also grow from the way people respond to difficult circumstances.

Loss can become solidarity.

Uncertainty can become courage.

And individuals can become leaders when they recognise that others need them.

Malahayati’s maritime world was very different from ours today.

Most of us will never command a fleet.

We may never stand on a ship facing an approaching enemy.

But we will all experience our own waves.

Sometimes the waves are disappointment.

Sometimes they are uncertainty.

Sometimes they are change.

And sometimes they are loss.

The lesson is not that we should become warriors.

The lesson is that a difficult wave does not always have to make us sink.

Sometimes it can teach us how to stand together.

Sometimes it can teach us how to lead.

A Little Question for KawanCita

Imagine that one of your friends is going through a difficult time.

Would being brave mean telling them not to feel sad?

Or could being brave mean staying beside them and helping them move forward?

That is something we can learn from the story of Malahayati and the Inong Balee:

strength can grow when people support one another.

The sea may bring powerful waves.

But people do not always have to face them alone.

Serial Punggawa Laut: Episode 1 Ratu Sima

The Queen Who Taught a Kingdom to Be Honestejujuran dari Pesisir Jawa

This image is a creative illustration for storytelling and educational purposes


Hello, Friends of Cita & Nesia!

Long, long ago, on the northern coast of Java, there was a kingdom called Kalingga.

It was a place close to the sea.

Ships travelled across the waters. Traders came from distant places. People carried goods, stories, languages, and new ideas from one harbour to another.

And in this busy maritime kingdom lived a remarkable ruler.

Her name was Queen Sima, or Ratu Sima.

Ratu Sima was known for something very important.

She believed that a strong kingdom needed honest people.

Not only honest traders.

Not only honest citizens.

But also honest leaders.

And there is an old story about her that has been remembered for generations.

The Mysterious Bag of Gold

One day, a visitor wanted to find out whether the people of Kalingga were really as honest as everyone said.

So, he placed a bag filled with gold beside a road.

Then he waited.

People walked past it.

Some may have noticed it.

Some may have wondered who had left it there.

But nobody took it.

One day passed.

Then another.

And another.

Still, the bag remained in the same place.

Imagine that!

A bag of gold sitting beside a busy road, and nobody carried it home.

Why?

Because the people knew that something that did not belong to them should not be taken.

Then one day, someone from the royal family passed along the road.

By accident, his foot touched the bag.

When Ratu Sima heard what had happened, she faced a difficult decision.

Should she ignore it because the person belonged to her own family?

Ratu Sima said no.

Rules could not be only for ordinary people.

A leader and her family also had to respect them.

According to the story, Ratu Sima first ordered a very serious punishment. After discussion with her advisers, the punishment was directed only towards the foot that had touched the bag.

The story may sound very strict to us today.

But the message remembered through generations is much simpler:

Honesty matters, even when nobody is watching.

What Does This Have to Do with the Sea?

You might be wondering:

“Cita, Nesia, this is a story about a bag of gold. Where is the ocean?”

Good question!

Kalingga was part of a world connected through the sea.

Ships could carry spices, ceramics, textiles, food, and many other things.

But successful maritime connections needed something else too.

Trust.

Imagine being a trader arriving by ship in a place you had never visited before.

Would you feel comfortable trading with people you could not trust?

Would you return to a harbour where agreements were often broken?

Probably not.

Ships and ports may connect places physically, but trust connects people.

That is why values such as honesty, fairness, and responsibility can also be part of a maritime society.

A Maritime Mindset Can Begin with Character

Sometimes, when we hear the words maritime nation, we imagine big ships, busy ports, fishing boats, sailors, or naval fleets.

Those things are certainly part of a maritime world.

But CitaNesia invites us to look a little deeper.

A maritime society is also made of people.

And people bring their values wherever they go.

They bring them onto boats.

Into markets.

Across harbours.

Into communities.

And into the decisions they make.

Ratu Sima’s story reminds us that maritime strength is not only about how many ships a country has.

It can also be about the character of the people who live within that maritime world.

CitaNesia Insight

Ratu Sima’s story gives us a simple but powerful lesson:

A maritime mindset is not only about understanding the sea. It is also about developing the values that allow people to live, trade, travel, and work together across it.

Honesty creates trust.

Trust strengthens relationships.

And strong relationships help connect communities across islands and seas.

Indonesia’s maritime story, therefore, is not only a story of ships, ports, sailors, and oceans.

It is also a story of people and values.

Perhaps that is one of the most important things we can learn from Ratu Sima.

The sea connects our islands.

Character helps connect our people.

A Little Question for KawanCita

Imagine you found something valuable that did not belong to you.

What would you do?

And why do you think honesty is important when people live and work together?

Maybe the first step towards developing a maritime mindset begins with something very small:

learning how to become someone others can trust.
