History of Seruyan Regency: Coastal Traces in the Heart of Central Kalimantan

Seruyan Regency, with a vast area of 15,368.96 km², is a region with a long historical root as a trade hub between the coast and the interior of Central Kalimantan. Bordering six administrative regions—Katingan Regency, East Kotawaringin Regency, West Kotawaringin Regency, Lamandau Regency, as well as West Kalimantan Province to the north and the Java Sea to the south—Seruyan has held a strategic role in local geopolitics since ancient times.

##

Origins of the Name and the Sultanate Era

Etymologically, the name "Seruyan" originates from the word "Seru," which refers to a type of aquatic plant or the activities of local communities along the Seruyan River. Before the colonial era, this region was under the influence of the Banjar Sultanate. In the 17th century, the Pembuang area (the early administrative center of Seruyan) became an important port for pepper commodities and forest products. Legendary local figures, such as Datu Samuda, were known as respected leaders in defending the sovereignty of the coastal region from pirates.

##

Colonial Era and the 1787 Treaty

A turning point in Seruyan's history occurred on August 13, 1787, when Sultan Tahmidullah II of Banjar ceded the coastal areas of Kalimantan, including Pembuang, to the VOC (Dutch). From then on, Seruyan became part of the Afdeeling Kotawaringin. The Dutch were highly interested in its timber and marine product potential. During this period, Kuala Pembuang began to develop as a small administrative center connecting river routes to upstream areas such as Hanau and Seruyan Hulu.

##

Independence Struggle Era

After the proclamation in 1945, the spirit of independence spread to the remote corners of Seruyan. Figures like Ahmad Bakar and several local fighters were actively involved in underground movements against NICA (Netherland Indies Civil Administration). Seruyan became an important logistics base for fighters moving along the river to avoid Dutch sea patrols. The region officially became part of Central Kalimantan Province when the province was formed on May 23, 1957, through Emergency Law Number 10 of 1957.

##

Regional Autonomy and Modernization

Administratively, Seruyan was long under the umbrella of East Kotawaringin Regency. However, the drive to accelerate development led to Seruyan officially becoming an independent regency on July 2, 2002, based on Law No. 5 of 2002. H. Darwan Ali is recorded as the first Regent who laid the foundation for modern infrastructure development, including the development of Teluk Segintung Port, which is now an icon of the region's maritime economy.

##

Cultural Heritage and Identity

Seruyan's culture is a harmonious blend of Dayak traditions in the upstream areas and Malay-coastal culture in the downstream areas. One of the preserved traditions is Malamang and traditional ceremonies related to the river's life cycle. Historical sites such as the Jami Nurul Azhar Mosque in Kuala Pembuang bear silent witness to the peaceful spread of Islam in the coastal region. Today, with the motto "Gawi Hatantiring" (Working Together), Seruyan continues to transform from an isolated region into a new economic powerhouse in Central Kalimantan through its abundant oil palm plantations and fisheries.

Geography

#

Geographical Profile of Seruyan Regency, Central Kalimantan

Seruyan Regency is one of the strategic administrative regions in Central Kalimantan Province, covering an area of 15,368.96 km². Astronomically, this regency is located between 0°77' South Latitude and 3°56' South Latitude, and 111°49' East Longitude and 112°84' East Longitude. As a region situated in the central part of the province, Seruyan possesses unique geographical characteristics, stretching from highlands in the north to the coastline of the Java Sea in the south.

##

Topography and Landscape

Seruyan's topography is highly varied. The northern region is dominated by hills with altitudes ranging from 50 to 500 meters above sea level, forming part of the Schwaner Mountains. In this area, narrow valleys are formed between steep slopes. Conversely, the central to southern regions consist of lowlands, peat swamps, and gentle coastal areas. The regency directly borders six regions: Katingan Regency to the east, East Kotawaringin Regency to the northeast, West Kalimantan Province to the northwest, and Lamandau and West Kotawaringin Regencies to the west.

##

Hydrology and Water Bodies

The lifeblood of this regency flows through the Seruyan River, which bisects the region from north to south for approximately 350 kilometers. This river serves as the main transportation route and an irrigation source. Besides rivers, Seruyan has a unique geographical feature in the form of Lake Sembuluh. As the largest lake in Central Kalimantan, Lake Sembuluh plays a crucial role in the freshwater ecosystem and serves as the estuary for several small rivers in its vicinity before flowing into the sea.

##

Climate and Seasonal Variations

Seruyan has a tropical wet climate with high humidity. Weather patterns are influenced by monsoon winds, with the rainy season typically occurring between October and April, and the dry season from May to September. Annual rainfall ranges between 2,000 to 3,500 mm. In the southern coastal region, the influence of sea breezes strongly affects daily temperatures, while in the upstream (northern) region, temperatures tend to be cooler, especially at night, due to elevation factors.

##

Natural Resources and Biodiversity

Seruyan's natural wealth includes forestry, oil palm plantations, and mining such as iron ore and zircon. Part of Seruyan is within Tanjung Puting National Park, an important ecological zone that is the natural habitat of the Bornean Orangutan (Pongo pygmaeus). The ecosystems here are highly diverse, ranging from dipterocarp tropical rainforests in the north, peat swamp forests in the center, to mangrove forests along the southern coastline, which protect the coast from abrasion by the Java Sea.

Culture

Cultural Richness of Seruyan: Harmony of the Coast and Interior of Central Kalimantan

Seruyan Regency, spanning 15,368.96 km² in the heart of Central Kalimantan, is a unique region that blends the coastal ecosystem of the Java Sea with lush tropical rainforests. Its location bordering six neighboring regions—including East Kotawaringin and Katingan—makes Seruyan a meeting point for various Dayak sub-ethnic groups and dynamic coastal communities.

##

Traditions and Ceremonies

The life of the Seruyan people is greatly influenced by the presence of the Seruyan River that bisects the region. One of the most prominent traditions is the Mamapas Biduk Ritual. This ceremony is performed by the fishing communities in Kuala Pembuang as a form of gratitude and a prayer for safety before going to sea or to cleanse boats from negative energy. Additionally, the Dayak communities in the upstream areas, such as in Seruyan Hulu District, still hold firmly to the Tiwah tradition, a ceremony for escorting ancestral remains to the Sandung (a small house for storing bones), symbolizing the soul's perfect journey to the afterlife.

##

Traditional Dance and Music

Performing arts in Seruyan reflect a blend of Dayak culture and coastal Malay influences. Pesisir Dance is often performed during harvest festivals or to welcome distinguished guests, with movements that are more fluid and dynamic than inland Dayak dances. On the other hand, Mandau Dance remains a symbol of the courage of Seruyan Dayak youth in defending their homeland. These performances are usually accompanied by the beats of the Garantung (a typical Dayak gong) and the strumming of the Kalimantan Kecapi, creating a magical harmony that echoes along the riverbanks.

##

Local Cuisine and Flavors

Seruyan's coastal and river-rich geography has given birth to culinary masterpieces based on fish. Kerupuk Pipih is the most famous culinary icon of Kuala Pembuang, made from pipih fish (belida), which is now becoming rare. In addition, there is Fried Seluang Fish and Wadi, a technique of fermenting river fish using salt and samu (toasted rice). The sour, salty taste and pungent aroma make Wadi an authentic side dish representing the traditional food security of the local community.

##

Language and Local Expressions

The people of Seruyan use Ngaju Dayak Language as a lingua franca in the interior, but in the coastal areas, there is a distinct dialect called Banjar Kuala Language with a strong local accent. The expression "Manas" is often used to describe annoyance, while the terms "Guring" (sleep) and "Makan Pai" (eat first) are part of daily conversations that strengthen brotherhood among residents.

##

Traditional Attire and Textiles

During traditional events, the people of Seruyan wear Batik Seruyan whose motifs are inspired by local natural wealth, such as the Pipih Fish and Galam Fruit motifs. Men often wear Saputangan Kepala (headscarf) and Wood Bark Vests adorned with beads, while women wear long kebaya paired with sarongs with the Pucuk Rebung motif, reflecting the Malay cultural influence in the coastal region of Central Kalimantan.

Seruyan Regency, with a vast area of 15,368.96 km², is a destination that offers a harmony between its extensive coastline and lush tropical rainforests. Strategically located in the central part of Central Kalimantan and directly bordering six neighboring regions, Seruyan holds authentic natural and cultural wealth.

##

Natural Wonders: From Coastline to Protected Forests

As a coastal area, Seruyan boasts a prime destination: Sungai Bakau Beach. This beach is unique as it is the meeting point of fresh river water and salty sea water, creating a stunning gradation of water colors. Furthermore, Seruyan is the main gateway to Tanjung Puting National Park (TNTP) via the Sekonyer area. Here, tourists can witness the wild life of Orangutans in their natural habitat. For lovers of aquatic ecosystems, Lake Sembuluh, the largest lake in Central Kalimantan, offers a magical sunset view and the tranquil life of traditional fishermen.

##

Cultural Traces and Local Wisdom

Seruyan's culture is deeply influenced by the Dayak and coastal Malay ethnic groups. Tourists can visit traditional houses and witness the creation of local handicrafts, such as rattan weaving. Although it does not have large temples, Seruyan's historical wealth is preserved in ancient burial sites and traditional customs that are still practiced, such as thanksgiving ceremonies for sea and land harvests, demonstrating local wisdom in maintaining natural balance.

##

Adventure and Outdoor Activities

For adrenaline seekers, Seruyan offers the experience of navigating calm rivers by klotok (traditional boat). Penetrating the dense forest while observing proboscis monkeys (bekantan) and endemic Kalimantan birds is an unforgettable experience. Fishing activities in the waters of Lake Sembuluh or camping around the coastal areas are also popular choices for those who want to connect with nature.

##

Culinary Tourism and Hospitality

A visit to Seruyan is incomplete without tasting fresh grilled or fried Jelawat Fish from the river. Due to its coastal location, processed seafood products like Seruyan's signature shrimp paste are must-have souvenirs. Local residents are known for their openness and friendliness, often inviting tourists for casual conversations at roadside coffee stalls. For accommodation, there are various options ranging from simple guesthouses in the center of Kuala Pembuang to local homestays that provide an experience of living with the local community.

##

Best Time to Visit

The best time to visit Seruyan is during the dry season, between May and September. During this period, land access is easier, and wildlife observation activities in the national park are maximized as animals tend to gather around water sources. Seruyan is not just a destination, but a journey to rediscover the connection between humans and the wild nature of Borneo.

Economy

Economic Profile of Seruyan Regency: Synergy of Agrarian and Maritime Sectors

Seruyan Regency, strategically located in the central part of Central Kalimantan Province, is a region of 15,368.96 km² with unique geographical characteristics. Bordering six administrative regions—including East Kotawaringin and Katingan—Seruyan possesses a competitive advantage in its extensive coastline along the Java Sea (Indonesian Sea). This condition creates a strong economic structure in the plantation, fisheries, and processing industries sectors.

##

Plantation Sector and Processing Industry

The backbone of Seruyan's economy is dominated by the plantation sub-sector, especially oil palm. The presence of various large private companies (PBS) has driven the growth of new economic centers in the upstream and central regions. Besides palm oil, rubber remains a traditional commodity supporting the people's economy. Industrial downstreaming has begun to develop with the establishment of Crude Palm Oil (CPO) processing plants, which absorb thousands of local workers and increase the added value of the regional gross domestic product (PDRB).

##

Maritime Economy and Fisheries

As a coastal region, the maritime economy plays a crucial role. Kuala Pembuang, as the regency capital, functions as a fish landing center. Local fishermen utilize marine wealth for export commodities such as tiger prawns and pomfret. In addition to capture fisheries, pond cultivation along the southern coastline is an important source of income. Processed seafood products, such as pipih fish crackers and Seruyan's signature shrimp paste, have become flagship products that penetrate the national market.

##

Traditional Crafts and Tourism Potential

The creative economy sector is supported by traditional rattan and purun weaving crafts produced by local communities. These products not only have artistic value but also export potential as environmentally friendly lifestyle goods. On the other hand, the tourism sector is beginning to flourish with the icon of Tanjung Puting National Park, part of which is in Seruyan, as well as Sungai Bakau Beach. The development of ecotourism is starting to open business opportunities in hospitality, culinary, and tour guiding for local residents.

##

Infrastructure and Employment Trends

The local government continues to accelerate transportation infrastructure development to break the isolation of the region. The development of Segintung Port is a strategic project expected to become the main export gateway for Central Kalimantan's commodities, significantly reducing logistics costs. In terms of employment, there has been a shift from the primary agricultural sector to the service and trade sectors as inter-district accessibility improves.

Overall, Seruyan's economy is transforming from dependence on natural resource extraction towards strengthening the processing industry and maritime services sectors. With optimal utilization of the coastline and infrastructure integration, Seruyan is projected to become a vital new economic axis in Central Kalimantan.

Demographics

#

Demographic Profile of Seruyan Regency, Central Kalimantan

Seruyan Regency is one of the strategic regions in Central Kalimantan Province with an area of 15,368.96 km². As a region characterized by coastal areas in the south and hills in the north, Seruyan's population dynamics reflect a blend of agrarian communities, fishermen, and plantation industry workers.

Population Size, Density, and Distribution

Based on the latest data, the population of Seruyan Regency has exceeded 150,000 people. Despite its very large area, its population density is considered low, around 10-11 people per km². Population distribution is uneven; the largest concentration of people is in Kuala Pembuang (Seruyan Hilir District) as the center of government and economy, as well as in areas bordering oil palm plantations in the central part. The six directly bordering regions, including East Kotawaringin and Katingan, influence settlement patterns along land transportation routes.

Ethnic Composition and Cultural Diversity

Seruyan's demographics are highly heterogeneous. The Dayak ethnic group (especially Ngaju Dayak and Bakumpai Dayak) and the Malay ethnic group are the indigenous people inhabiting the banks of the Seruyan River. However, strong migration flows have brought significant influence from the Javanese, Banjar, and Bugis ethnic groups. The presence of transmigrants in several districts has created cultural enclaves that enrich the social structure, where local cultural syncretism and traditions of newcomers coexist harmoniously.

Age Structure and Education

Seruyan's population structure is dominated by the productive age group (15-64 years), forming an expansive population pyramid widening in the middle. This indicates a large labor potential, but also challenges in providing employment. In the education sector, literacy rates have reached over 95%, although there is a disparity in higher education levels between urban and remote rural areas.

Urbanization and Migration Patterns

The regency experiences significant in-migration, driven by the expansion of the oil palm and mining sectors. The phenomenon of "rural-urban migration" is evident in the movement of young people from villages to Kuala Pembuang for education or employment in the service sector. As a coastal region, Seruyan also attracts seasonal fishermen from outside the island who settle along the southern coastline, adding to the demographic uniqueness of Central Kalimantan's coastal areas.

Seruyan: The Vast Yet Tranquil Coastal Heart of Central Kalimantan

Seruyan perfectly represents the geographical characteristics of Central Kalimantan. With an area of 15,368.96 km², this regency slightly exceeds the average area of regencies/cities in the province (15,300 km²). However, this area figure holds an interesting contrast in terms of population density. With a provincial average of only 25 people/km², Seruyan is a region where green open spaces and natural ecosystems still dominate its landscape compared to dense settlements. This creates challenges as well as opportunities in equitable infrastructure development amidst a massive natural landscape.

Economically, Seruyan stands on two giant regional pillars: coal mining and oil palm plantations. As a coastal region situated in the central position, Seruyan serves as a crucial logistics corridor. However, dependence on these extractive sectors demands a transition towards sustainability. Its coastal position provides a comparative advantage over inland regencies, especially in terms of sea access that supports the distribution of industrial products to other islands.

In the context of tourism, although Central Kalimantan ranks #24 nationally, Seruyan is an "untouched hidden gem." Unlike popular destinations that rely on modern infrastructure, Seruyan's appeal lies in its natural authenticity. As home to a part of Tanjung Puting National Park, Seruyan offers a strong conservation narrative. Here, tourism is not just entertainment, but an effort to maintain the balance between the exploitation of major industrial economies and the preservation of coastal biodiversity and rainforests.

Curator's Perspective: Traces of Conservation Amidst Expansion

When researching Seruyan, one fact that stands out is how this region has managed to maintain its status as a last bastion of world orangutan conservation amidst the encroachment of large-scale industries. It is astonishing to see how a region so economically dependent on the expansion of oil palm and coal is also the gateway to the legendary Tanjung Puting National Park.

For me, Seruyan is a living geographical paradox. On one hand, we see vast maps of industrial concessions, yet on the other, there is a global commitment to protect wetland ecosystems and peat swamp forests. The fact that Seruyan has a long coastline makes it a crucial habitat for mangrove ecosystems, which function as a shield against abrasion and a massive carbon sink.

What impresses me is how Seruyan is not just a "number" in the statistics of Central Kalimantan's area, but a real battleground between industrial modernization and nature conservation. Exploring Seruyan virtually through data gives me a new perspective that the development of a coastal region does not always have to mean massive urbanization, but can be a harmonious spatial management between economic and ecological functions.
