Reading Physics Through Tanean Lanjhang: Traditional Settlement Patterns as Cultural Contexts for Science Education

Physics often feels like a subject that lives in a separate world from daily life, a collection of abstract rules about how things move and heat up that students must memorize for a test. Yet, the principles that govern the universe are constantly at work in the places we live, the clothes we wear, and the food we cook. When a house stays cool on a hot day without electricity, or when wind rushes through a narrow alley, invisible forces of air pressure and heat transfer are doing the heavy lifting. For decades, science education has struggled to bridge the gap between these textbook formulas and the lived experiences of students, often presenting scientific knowledge as something universal and detached from local culture. This disconnect can make learning feel irrelevant, as if the laws of nature only apply in a laboratory rather than in the community where a child grows up.

A new study from researchers in Indonesia seeks to close that gap by looking at a traditional way of building and living that has existed for generations among the Madurese people. The researchers focused on a specific settlement pattern known as Tanean Lanjhang, a layout where homes, kitchens, and animal pens are arranged in a long, orderly row facing a shared central courtyard. While this arrangement is deeply rooted in social values, family privacy, and cultural tradition, the researchers wondered if it also held a hidden layer of scientific wisdom. They set out to see if the way these communities have organized their space for centuries actually demonstrates an intuitive understanding of physics, specifically how air moves and how heat travels.

The team, consisting of educators and scientists from universities in Madura, approached the Tanean Lanjhang not just as a cultural artifact, but as a living laboratory. They spent time in the settlement, observing the physical layout, taking photographs, and speaking with community leaders who have lived there all their lives. They also gathered a group of experts, including physicists and education specialists, to discuss what they saw. Their goal was to map the physical features of the settlement—such as the direction the houses face, the materials used for walls and roofs, and the shape of the courtyard—to the scientific concepts that explain why these houses feel comfortable even in the tropical heat.

What they found was that the traditional layout is a masterclass in natural ventilation and temperature control. The settlement is designed with a long, open courtyard in the center, flanked by buildings on either side. When the wind blows from the east, a common occurrence in the region, it is funneled into this narrow space. Because the air is forced through a tighter channel between the buildings, it speeds up. This acceleration creates a drop in air pressure, a phenomenon known as Bernoulli's principle, which helps pull air through the windows and vents of the houses. The design essentially uses the wind itself to create a breeze that circulates through the living spaces, cooling the interior without any mechanical fans.

The orientation of the buildings also plays a crucial role. The main houses face south, while the kitchens and animal pens face north, creating a specific flow that guides the wind through the entire compound. The researchers noted that the community has long understood that this arrangement keeps the inside of the house cool, even when the sun is blazing outside. This is not just a matter of luck; it is a result of how the buildings interact with the environment. The height of the courtyard walls and the placement of windows create a path for air to enter at one point and exit at another, a process called cross-ventilation that relies on differences in air pressure to keep the air moving.

Heat management is handled through the materials and the shape of the roofs. The houses feature high, steep roofs that resemble a mountain peak, a style that allows hot air to rise and escape through gaps near the top. Since hot air is lighter than cool air, it naturally floats upward, and the tall roof gives it a place to go, preventing the heat from getting trapped inside the living area. The walls are constructed from a mixture of fired bricks, soil, and white lime. The researchers found that the white lime acts as a natural insulator. While the bricks can absorb a significant amount of heat, the layer of lime slows down the transfer of that heat into the room. This combination keeps the interior temperature stable and relatively cool compared to the outside air.

The study argues that this traditional knowledge is not merely a set of customs to be preserved as history, but a valid source of scientific understanding that can be used in modern classrooms. By showing students that the physics of airflow and heat transfer are already present in their own neighborhoods, educators can make complex concepts feel familiar and meaningful. The researchers suggest that instead of treating local wisdom as a simple illustration for pre-existing scientific facts, schools should recognize these cultural practices as a way of knowing that can help students build a deeper, more personal understanding of science.

The findings highlight that the people of Madura have been applying principles of fluid dynamics and thermodynamics for generations, long before these concepts were named in a textbook. The settlement pattern is a unified system where social values and physical laws work together to create a comfortable living environment. By studying the Tanean Lanjhang, the researchers have identified a clear path for integrating local culture into science education, proving that the answers to scientific questions are often found in the everyday world right outside the classroom door. This approach does not replace formal science but enriches it, showing that the laws of physics are not just abstract ideas but are woven into the fabric of daily life.
