History and Development of Dumai City: Gateway to Riau's Coast

Origins and the Legend of Putri Tujuh

Dumai, a strategic coastal city in Riau Province with an area of 2,443.46 km², has historical roots intertwined with legends and geographical facts. The name "Dumai" is believed to originate from the local word "d'umai," referring to a type of aquatic animal, but the most popular narrative is the legend of Putri Tujuh (Seven Princesses). This story tells of seven princesses from the Seri Bunga Tanjung Kingdom who were hidden in protective shelters during a war against the Aceh Kingdom. The tragic deaths of these princesses became a collective memory, now preserved through an ancient burial site in the Pertamina refinery area, which forms the emotional identity of the Dumai community.

Colonial Era and Japanese Arrival

Administratively, during the Dutch East Indies era, Dumai was part of the Siak Sri Indrapura Kingdom. Its geographical position on the northern coast of Riau, directly facing the Strait of Malacca, made it an important observation point. However, a major transformation began in the 1930s when an American oil company, California Standard Oil Company (now Chevron/Pertamina Hulu Rokan), started exploration in the interior of Riau. During the Japanese occupation (1942-1945), Dumai played a tragic role in military history through the construction of the death railway from Muaro Sijunjung to Pekanbaru. Although the railway did not reach Dumai directly, the port of Dumai began to be eyed as a logistics exit point for the war on the east coast of Sumatra.

Independence Era and the Oil Boom

After the proclamation of Indonesian independence, Dumai's status rapidly evolved from a small fishing village to an industrial center. A crucial moment occurred in 1958 when Caltex began crude oil export operations through the Dumai terminal. On July 15, 1971, the Putri Tujuh Refinery (UP II Dumai) officially commenced operations, marking a new era for Dumai as a national strategic industrial city. This development brought large-scale migration of Malay, Minang, Javanese, and Batak ethnic groups, forming a heterogeneous yet harmonious social structure. Politically, Dumai was initially part of Bengkalis Regency before officially gaining the status of an Administrative City in 1979, and later upgraded to an Autonomous City on April 20, 1999, based on Law No. 16 of 1999.

Cultural Heritage and Modernity

As part of the Malay land, Dumai upholds the custom of Bersendi Syarak, Syarak Bersendi Kitabullah (Custom is based on Islamic law, Islamic law is based on the Quran). Cultural heritage such as the Tari Persembahan (Offering Dance) and the Tepuk Tepung Tawar (Sprinkling of Rice Flour) tradition remain preserved amidst the roar of industry. Monuments of struggle like the Tugu Elang (Eagle Monument) in the city center and historical sites like the Dutch-era cannons bear silent witness to the transition of eras. Today, bordering Bengkalis Regency to the north and west, and Siak Regency to the south, Dumai has transformed into the largest CPO export port in Indonesia. Dumai's history is a narrative of how a quiet coastal settlement evolved into a pillar of the national economy in the Strait of Malacca, without abandoning its noble Malay traditional roots.

Geography

#

Geography of Dumai City: Gateway to Riau's Northern Coast

Dumai City is a unique administrative entity in Riau Province, holding the distinction of being one of the cities with the largest land area in Indonesia, reaching 2,443.46 km². Geographically, this region is located at coordinates 1°23'00"–1°24'23" North Latitude and 101°23'37"–101°28'13" East Longitude. As a strategic port city, Dumai is situated in the northern part of Riau Province and directly borders the Strait of Malacca to the north. Administratively, this region is surrounded by three main neighboring areas: Bengkalis Regency to the north, east, and west, and Rokan Hilir Regency to the west and south.

##

Topography and Landscape

Dumai's landscape is dominated by flat lowlands with elevations ranging from 0 to 25 meters above sea level. The soil characteristics largely consist of organosol (peat) and red-yellow podzolic soils with high acidity. As a coastal region, Dumai has a coastline stretching along the Indonesian Sea, particularly facing Rupat Island, which acts as a natural wave breaker. Although it does not have steep mountains or valleys, Dumai's topography is significantly influenced by tidal sea levels, which often cause saltwater intrusion inland.

##

Hydrology and Water Systems

The natural drainage system in Dumai is supported by several main rivers that serve as the lifeblood of the local ecosystem. The Dumai River, Mesjid River, and Rakit Kulim River flow through the region towards their estuaries in the Strait of Malacca. These rivers have calm currents with high mud sedimentation, creating a rich but environmentally sensitive estuarine ecosystem.

##

Climate and Weather Patterns

Dumai has a tropical wet climate with seasonal variations influenced by monsoon winds. The average air temperature ranges between 23°C and 33°C, with high humidity throughout the year. The dry season typically occurs from February to August, while the rainy season takes place between September and January. A unique phenomenon in this region is its vulnerability to haze due to the peat soil characteristics, which are prone to burning during extreme dry seasons.

##

Natural Resources and Biodiversity

Dumai's mineral wealth is centered on its oil reserves, making it a major oil processing industrial center in Indonesia. Besides energy, forestry and oil palm plantations dominate land use. In the coastal ecological zone, there are mangrove forests that serve as habitats for various species of mud crabs, shrimp, and migratory birds. The tropical forest vegetation in the interior still harbors biodiversity, although its area continues to shrink due to the expansion of plantation land. The presence of the Dumai Strait also serves as an important ecological zone for international marine life traffic, connecting the waters of the Indian Ocean and the Natuna Sea.

Dumai's artistic heritage is heavily influenced by Malay culture. Tari Persembahan (Makan Sirih) (Offering Dance - Betel Offering) is a mandatory opening performance to welcome honored guests, where dancers carry a *tepak sirih* (betel tray) as a symbol of hospitality. Additionally, Zapin Api is a rare and magical performance sometimes staged in this region, featuring a dance on hot embers. In music, the beat of Rebana Kompang (frame drum ensemble) and the melodies of Gambus (lute) always accompany spontaneous pantuns, which are characteristic of the local community's linguistic intelligence.

Signature Coastal Cuisine

Dumai's coastal geography greatly influences its culinary flavors.

The people of Dumai also enjoy Mee Sagu (Sago Noodles), a culinary heritage made from sago that reflects local food resilience.

#

Language and Dialect

The primary language used is Malay language, Riau Coastal dialect. This dialect has a characteristic pronunciation of the vowel 'a' at the end of words, which often changes to a weak 'e' (as in 'apa' becoming 'ape'). A distinctive phrase like "Takkan Melayu Hilang di Bumi" (The Malays will never disappear from the Earth) serves as a slogan that ignites the spirit of preserving local identity amidst the modernization of an international port.

Traditional Attire and Textiles

In terms of dress, the people of Dumai are proud of the Baju Kurung for women and Baju Melayu Cekak Musang for men, complemented by a Samping (sarong) made from Siak weaving or songket with floral motifs. The motifs on traditional fabrics often draw inspiration from nature, such as bamboo shoots, symbolizing the hope for continuous growth and benefit to others.

#

Religious Practices and Festivals

As a predominantly Muslim city, Islamic holidays like Eid al-Fitr and Eid al-Adha are celebrated festively through the Lampu Colok (Torchlight) tradition. Leading up to the night of the 27th of Ramadan (malam likuran), thousands of kerosene lamps are arranged to form mosque gates or ships, illuminating the corners of Dumai City with artistic light. Furthermore, Multi-Ethnic Cultural Festivals are often held to celebrate the diversity of ethnic groups (Minang, Javanese, Bugis, Chinese) who live harmoniously in this port city.

##

Tourism and Service Sector

The service and tourism sectors are developing in line with improved accessibility. Teluk Makmur Beach and the Bandar Bakau ecotourism area are destinations that drive the local economy through the seafood culinary sector. The growth of star-rated hotels and shopping centers reflects the increasing purchasing power of the community, driven by high employment in the industrial sector.

##

Employment and Development Trends

Employment trends in Dumai show a shift from the primary sector to the secondary and tertiary sectors.

Dumai City, located in the northern part of Riau Province, is an administrative entity with an area of 2,443.46 km². As the third-largest city in Indonesia by area, Dumai's demographic characteristics are strongly influenced by its strategic location on the coast of the Strait of Malacca and its direct borders with Bengkalis Regency and Rokan Hilir Regency.

Dumai is a miniature Indonesia on Riau's coast. Although historically Malay land, the development of the oil industry (Pertamina) and the port has attracted large waves of migration. Javanese ethnic groups are now the majority, followed by Malays, Minangkabau, Batak, and Chinese. This diversity creates a harmonious social dynamic, where the open coastal culture blends with the work ethic of industrial migrants.

Age Structure and Population Pyramid
