Remove ads
Sidoarjo Regency (Javanese: ꦑꦧꦸꦥꦠꦺꦤ꧀ꦱꦶꦢꦲꦂꦗ, romanized: Kabupatèn Sidaharja) is a regency in East Java, Indonesia. The regency has its capital in the Sidoarjo District and covers an area of approximately 719.34 km², making it the geographically smallest regency in the province. Nevertheless, Sidoarjo is densely populated, with an estimated 2,027,874 residents as of mid-2024 (about 2,800 people per km²). Its location south of Surabaya makes it an integral part of the Gerbangkertosusila metropolitan area, sharing borders with Surabaya, Gresik, Pasuruan, Mojokerto, and the Madura Strait.

Administratively, Sidoarjo Regency is divided into 18 districts, 28 urban villages (kelurahan), and 318 rural villages (desa). The most densely populated districts are located in the northern part, such as Waru and Taman, which serve as gateways to Surabaya and centers of urbanization. Meanwhile, coastal areas like Sedati and Porong lie at low elevations (0–3 meters) and are characterized by shrimp and milkfish ponds — which is why Sidoarjo is nicknamed the “Delta City” and the “Shrimp City.”[2]
Sidoarjo Regency traces its roots deep into the layers of ancient Javanese history — the region was originally part of the Kahuripan kingdom founded by Airlangga around 1019, with its capital at the mouth of the Brantas River, before it was divided into two kingdoms, Janggala and Kadiri, in 1045.[3] As part of Janggala, its ancient capital was located in Hujung Galuh (now partly within Sidoarjo and Surabaya), which developed into a major port for the Majapahit Empire in the 14th century. Traces of this era are still visible in structures like Pari Temple (established around 1371 during the reign of Hayam Wuruk) and Dermo Temple (believed to date from the mid-14th century), which showcase the distinctive red-brick architecture of Majapahit and stand as symbols of a glorious past.[4]
Sidoarjo Regency plays an increasingly important economic role as a major satellite city of Surabaya, marked by the presence of Juanda International Airport in Sedati — one of the busiest air gateways in Indonesia, handling around 14 million passengers annually, making it the third-busiest airport in the country.[5] The area's accessibility is enhanced by dedicated toll roads such as the Waru–Juanda Toll Road, which directly connects to the airport, as well as the Surabaya–Gempol Toll Road, which facilitates southbound distribution and improves the mobility of goods and people. In Sidoarjo’s urban center, the economic vibrancy is reflected in the numerous modern shopping centers: Lippo Plaza, Ciplaz Sidoarjo, Transmart Carrefour, and the Suncity Superblock.[6]
Sidoarjo Regency ranks highly in the Human Development Index (HDI) category in both East Java and Indonesia. In 2024, Sidoarjo’s HDI reached 82.31, placing it fourth in East Java after the cities of Malang, Surabaya, and Madiun, and categorizing it as “very high.”[7]

Economy
Summarize
Perspective
As a satellite region and part of Greater Surabaya, the Sidoarjo economy is valued at 197.24 Trillion IDR in 2020 and is the second-largest[10] in East Java after Surabaya.
Primary Sector
Although Sidoarjo Regency's land area is relatively small and densely populated, the primary sector still maintains a role in Sidoarjo's economy. Agriculture is mainly produced in the western and southwestern parts of Sidoarjo Tulangan District, Krembung District, and Balongbendo District. During the colonial era, Sidoarjo was famous for sugarcane production and it hosted several sugar mills owned by the Colonial government. After Independence, the Indonesian government nationalised all sugar mills in Sidoarjo. The sugarcane production sector peaked in the 70s and gradually declined since then, due to inflows of manufacturing investment and rapid urbanization that reduced the sugarcane planting area. Rice, banana, papaya, cassava, and several lowland vegetables are still popular crops.
Fisheries also still maintain a role. In the past, Sidoarjo was known as a fishing town, but the fishing sector was slowly declining as Sidoarjo became more urbanized. Fishing has been replaced by aquaculture as the main source of fish in Sidoarjo. Highly productive aquaculture is mainly produced in the eastern part of Sidoarjo Regency, and the main product is Milkfish and farmed shrimp which are mostly exported to the US and Japan. Sidoarjo is also famous for its processed fishery products, such as prawn cracker, fish cracker, shrimp paste and petis.
The mining sector could be neglected as it contributes very little to Sidoarjo economy. The main mining sector is natural gas, which is produced in Porong District. There are also several sand miners that operate in Jabon District.
Secondary Sector
Manufacturing is a main sector of the Sidoarjo economy with a contribution of nearly 40%. Sidoarjo manufacturing production is diversified and ranges from furniture to electronics products. There are numerous manufacturing plants in Sidoarjo. Among this are : Jatim Taman Steel (Steel Manufacturer), Avian (Paints and building material), Tunggal Djaja (Paints Production), Maspion (Household durable goods), Japfa Comfeed (Feedmills and poultry), Interbat (Pharmaceuticals), Integra (Furniture), Tjiwi Kimia (Paper), Kimberly-Clark's Softex (Non-durable consumer goods), Unicharm (Non-durable consumer goods), Polygon Bikes (Bikes), Alumindo (Aluminium products), Sekar Group (Food processing), Hisamitsu (Pharmaceutical), Lighting Solutions (Lamp), ECCO (Footwear), Samator (Industrial gas and chemicals), Bernofarm (Pharmaceutical), Muntjul Diamond (Vehicle body), Charoen Pokphand (Agribusiness) and many more.
There are thousands of small and medium manufacturers established in Sidoarjo. Garments, Food Processing, Footwear, Apparel, and Furniture are products that are usually produced by small and medium manufacturers in Sidoarjo. Many small and medium manufacturers produce traditional herbs, machinery, packaging, and metal products.
During the colonial era, there were 10 sugarmills in Sidoarjo and the oldest is Watu Tulis Sugarmills that built in 1838.[11] There remain three sugarmills in Sidoarjo. Among this are New Candi Sugarmills that built in 1911, Krembung Sugarmills, and Watu Tulis Sugarmills.
Tertiary Sector
The main tertiary sectors in Sidoarjo are wholesaling and retailing, food services, education, and financial services. As Sidoarjo is getting more urbanized, the tertiary sector is predicted to grow significantly. The fastest growth in the tertiary sector is recording in experience-related services, such as food services (notably restaurant, cafe) and movie theater. Education Services are also predicted to grow, as several private tutoring companies are opening a branch in Sidoarjo and private schools are gaining more students, due to increasingly population, income, and lack of capacity in state schools.

Lapindo Mud flow
Summarize
Perspective
Since May 2006, more than 10,000 people in the Porong District have been displaced by hot mud flowing from a natural gas well being drilled by Lapindo Brantas, an oil well company that is part of a conglomerate owned by Coordinating Minister for the People's Welfare Aburizal Bakrie.[12] Gas and hot mud started spewing from the well on May 28, when the drill penetrated a layer of liquid sediment. Attempts to pump concrete down the well did not stop the flow. While some scientists have speculated that the earthquake that struck Yogyakarta on May 27, the day before the well erupted, may have cracked the ground, creating potential pathways for the mud to reach the surface, others have suggested that the drilling procedure was faulty by not using a casing. This is likely to be incorrect as technical papers on the subject showed that there were up to four sets of casing installed and cemented in the well. Some 50,000 cubic metres of hot mud were erupting every day as of August; in September, the amount increased to some 125,000 cubic metres daily.[13] On September 26 barriers built to hold back the mud failed, resulting in the flooding of more villages. Gus Maksum, one of the thousands of Sidoarjo villagers displaced by the mud flow gives a detailed first-hand account of the first year of the disaster in his memoir Titanic Made By Lapindo.[14] As of late September 2006 scientists said that a mud volcano may have been forming, and could be impossible to stop.[15][16][17]
Climate
Sidoarjo has a tropical savanna climate (Köppen Aw) with moderate to little rainfall from May to November and heavy rainfall from December to April.
