Surabaya in the context of "Sumenep Regency"

East Java (Indonesian: Jawa Timur, Javanese: ꦙꦮꦶꦮꦺꦠꦤ꧀, romanized: Jawi Wétan, Madurese: Jhâbâ Tèmor) is a province of Indonesia located in the easternmost third of Java island. It has a land border only with the province of Central Java to the west; the Java Sea and the Indian Ocean border its northern and southern coasts, respectively, while the narrow Bali Strait to the east separates Java from Bali by around 2.29 kilometres (1.42 mi). Located in eastern Java, the province also includes the island of Madura (which is connected to Java by the longest bridge in Indonesia, the Suramadu Bridge), as well as the Kangean islands and other smaller island groups located further east (in the northern Bali Sea) and the Masalembu archipelago to the north. Its capital is Surabaya, the second largest city in Indonesia, a major industrial center and also a major business center. Banyuwangi is the largest regency in East Java and the largest on the island of Java.

The province covers a land area of 48,036.84 square kilometres (18,547.13 sq mi), and according to the 2010 Census, there were 37,476,757 people residing there, making it Indonesia's second-most-populous province; the 2020 Census showed an increase to 40,665,696 people, while the official estimate for mid 2024 was 41,914,499 (comprising 20,848,660 males and 20,965,880 females). Almost a quarter of the population lives inside the Greater Surabaya metropolitan area. East Java is inhabited by many different ethnic groups, such as the Javanese, Madurese and Chinese. Most of the people in East Java adhere to Islam, forming around 94% of the total population. Other religions are also practiced, such as Christianity, Buddhism and Confucianism which are mostly practised by Tionghoa people and immigrants from Eastern Indonesia and North Sumatra, and also Hinduism which are practised by the Tenggerese people in the Bromo Tengger Semeru National Park and the Balinese people inhabiting the easternmost part of the province bordering Bali as well as the dominant minority Indian Indonesians in Surabaya city.

The government of Indonesia defines a metropolitan area as an urban agglomeration where its spatial planning is prioritised due to its highly important influence on the country. The metropolitan areas in Indonesia are managed based on Presidential Regulation (Peraturan Presiden). The national government has established 10 metropolitan areas across the country, anchored by the cities of Jakarta, Surabaya, Bandung, Semarang, Medan, Makassar, Palembang, Denpasar, Banjarmasin, and Manado. Despite having no official metropolitan areas recognised on national level, there are several other cities whose urbanised area exceeds their city limits such as Yogyakarta, Malang, and Cirebon.

Bromo Tengger Semeru National Park (Indonesian: Taman Nasional Bromo Tengger Semeru; abbreviated as TNBTS) is a national park located in East Java, Indonesia, to the east of Malang, to the west of Lumajang, to the south of Pasuruan and Probolinggo, and to the southeast of Surabaya, the capital of East Java. It is the only conservation area in Indonesia that has a sand sea, the Tengger Sand Sea (Indonesian: Laut Pasir Tengger), across which is the caldera of an ancient volcano (Tengger) from which four new volcanic cones have emerged. This unique feature covers a total area of 5,250 hectares at an altitude of about 2,100 meters (6,900 ft). The massif also contains the highest mountain in Java, Mount Semeru (3,676 meters (12,060 ft)), four lakes (including, the isolated Ranu Tompe), and 50 rivers. It is named after the Tenggerese people. The explosion of the volcano that created the caldera, happened ca. 45.000 years ago, in an event similar to the Krakatau eruption.

The Tengger Sand Sea has been protected since 1919. The Bromo Tengger Semeru National Park was declared a national park in 1982.

The Cemoro Lawang (also known as Cemorolawang, Cemora Lawang, or Cemara Lawang) is a very small hamlet north-east of Mount Bromo (East Java), Indonesia with an altitude of 2,217 meters above sea level. Administratively, this hamlet is a part of Ngadisari Village, Sukapura, Probolinggo Regency. Cemoro Lawang is one of many routes that point to Tengger Caldera from the Probolinggo route. There is a viewpoint to see Mount Batok and Mount Bromo. It is principally a base for early morning climbs of Mt Bromo, an active volcano that stands in the middle of a Sand Sea. Many visitors approach the mountain from Surabaya which is about three hours drive away; others come from Bali.

Madurese (/ˌmædʒʊˈriːz/ MAD-juh-REEZ; Bhâsa Madhurâ, Pegon script: ݒا࣪سا ماڊۅرا࣪, Carakan script: ꦧꦱꦩꦝꦸꦫ, IPA: [bʰɤsa maʈʰurɤ]) is a language of the Madurese people, native to the Madura Island and eastern part of Java, Indonesia; it is also spoken by migrants to other parts of Indonesia, namely the Surabaya, Malang, Gresik, eastern salient of Java (comprising Pasuruan, Bondowoso, Probolinggo, Situbondo, Jember, Lumajang, to Banyuwangi), the Masalembu Islands, Raas Islands, and some on Kalimantan. It was traditionally written in the Javanese script, but the Latin script and the Pegon script (based on Arabic script) is now more commonly used. The number of speakers, though shrinking, is estimated to be 10–14 million, making it one of the most widely spoken languages in the country. Bawean language, which is a dialect of Madurese, is also spoken by Bawean people in Bawean Island, Indonesia. Then also by their descendants in Malaysia and Singapore.

Semarang (Javanese: ꦏꦸꦛꦯꦼꦩꦫꦁ, Kutha Semarang) is the capital and largest city of Central Java province in Indonesia. It was a major port during the Dutch colonial era, and is still an important regional center and port today. The city has been named as the cleanest tourist destination in Southeast Asia by the ASEAN Clean Tourist City Standard (ACTCS) for 2020–2022.

It has an area of 373.78 km (144.32 sq mi) and had a population of 1,555,984 at the 2010 census and 1,653,524 at the 2020 census, making it Indonesia's ninth most populous city after Jakarta, Surabaya, Bekasi, Bandung, Medan, Depok, Tangerang and Palembang; the official population estimate as at mid-2023 was 1,694,740, comprising 838,440 males and 856,310 females. The built-up urban area had 3,183,516 inhabitants at the 2010 census spread over two cities and 26 districts. The Semarang metropolitan area (a.k.a. Kedungsepur) has a population of over 6 million in 2020 (see Greater Semarang section). The population of the city is predominantly Javanese with significant Chinese presence.

Indian Indonesians are Indonesians whose ancestors originally came from the Indian subcontinent. Therefore, this term can be regarded as a blanket term for not only Indonesian Indians but also Indonesians with other South Asian ancestries (e.g. Pakistanis, Bangladeshis, etc.). According to the Indian Ministry of External Affairs, there were about 120,000 people of Indian origin as well as 9,000 Indian nationals living and working in Indonesia as of January 2012. Most of them were concentrated in the province of North Sumatra and urban areas such as Banda Aceh, Surabaya, Medan, and Jakarta. However, it is quite impossible to get correct statistical figures on the Indian Indonesian population, because some of them have merged and assimilated with the indigenous population to become indistinguishable from native Indonesians.

The Suramadu Bridge (Indonesian: Jembatan Suramadu, Javanese: Kreteg Suramadu, Madurese: Tètè Suramadu; from the abbreviation of Surabaya–Madura Bridge) is a cable-stayed bridge between Surabaya on the island of Java and southern Bangkalan Regency on the island of Madura in Indonesia. Opened in June 2009, the 5.4-kilometre-long (3.4 mi) bridge is the longest in Indonesia and the second-longest in the Southern Hemisphere. It is the first bridge to cross the Madura Strait.

The cable-stayed portion has three spans with lengths 192 metres (630 ft), 434 metres (1,424 ft), and 192 metres (630 ft). The bridge has two lanes, an emergency lane, and a dedicated lane for motorcycles in each direction.
