Karimunjawa Islands
Karimunjawa Islands or Karimunjava Islands ( id, Kepulauan Karimunjawa) is an archipelago of 27 islands in the Java Sea, Indonesia, approximately 80 kilometres northwest of Jepara. They have a total land area of 71.2 km2. The main island is known as Karimun (2,700 ha), while the second-largest island is Kemujan (1,400 ha). At the 2020 Census, the population of the island group was 9,789Badan Pusat Statistik, Jakarta, 2021. who lived on five of the islands. The population is largely Javanese, with pockets of Bugis and Madurese inhabitants. Javanese culture is dominant in the islands which are the only islands off Java where Javanese is the lingua franca. Twenty-two of the islands have been declared 2001 as a marine reserve, the Karimunjawa National Park. Five more islands are either privately owned or are under the control of the Indonesian Navy. The archipelago is served by Dewadaru Airport which provides scheduled airline services to Semarang and Surabaya. Islands an ...

Java Sea
The Java Sea ( id, Laut Jawa, jv, Segara Jawa) is an extensive shallow sea on the Sunda Shelf, between the Indonesian islands of Borneo to the north, Java to the south, Sumatra to the west, and Sulawesi to the east. Karimata Strait to its northwest links it to the South China Sea. It is a part of the western Pacific Ocean. Geography The Java Sea covers the southern section of the Sunda Shelf. A shallow sea, it has a mean depth of . It measures about east-west by north-southGoogleEarth and occupies a total surface area of . It formed as sea levels rose at the end of the last ice age. Its almost uniformly flat bottom, and the presence of drainage channels (traceable to the mouths of island rivers), indicate that the Sunda Shelf was once a stable, dry, low-relief land area (peneplain) above which were left standing a few monadnocks (granite hills that, due to their resistance to erosion, form the present islands).

Dewadaru Airport
Dewandaru Airport is an airport serving Karimunjawa, an archipelago in Central Java province of Indonesia. Dewandaru Airport is located on Kemujan Island in Karimunjawa. Kemujan Island is considered to be a part of Karimun Island, the largest island in Karimunjawa, as both islands are only separated by a small river. The distance from the airport to the city centre at Karimun Island is 22 kilometres. Dewandaru airport has one runway, with dimensions of 1,200 metres (3,937 ft) by 30 metres (98 ft) which allows the operation of aircraft up to ATR 72-600. Etymology The name of this airport comes from the endemic tree of Karimunjawa Karimunjawa Islands or Karimunjava Islands ( id, Kepulauan Karimunjawa) is an archipelago of 27 islands in the Java Sea, Indonesia, approximately 80 kilometres northwest of Jepara.

Sundaland
Sundaland (also called Sundaica or the Sundaic region) is a biogeographical region of South-eastern Asia corresponding to a larger landmass that was exposed throughout the last 2.6 million years during periods when sea levels were lower. It includes Borneo, Java, and Sumatra in Indonesia, and their surrounding small islands, as well as the Malay Peninsula on the Asian mainland. Extent The area of Sundaland encompasses the Sunda Shelf, a tectonically stable extension of Southeast Asia's continental shelf that was exposed during glacial periods of the last 2 million years. The extent of the Sunda Shelf is approximately equal to the 120-meter isobath. In addition to the Malay Peninsula and the islands of Borneo, Java, and Sumatra, it includes the Java Sea, the Gulf of Thailand, and portions of the South China Sea. In total, the area of Sundaland is approximately 1,800,000 km2. The area of exposed land in Sundaland has fluctuated considerably during the past recent ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Convicts
A convict is "a person found guilty of a crime and sentenced by a court" or "a person serving a sentence in prison". Convicts are often also known as "prisoners" or "inmates" or by the slang term "con", while a common label for former convicts, especially those recently released from prison, is "ex-con" ("ex-convict"). Persons convicted and sentenced to non-custodial sentences tend not to be described as "convicts". The label of "ex-convict" usually has lifelong implications, such as social stigma or reduced opportunities for employment. The federal government of Australia, for instance, will not, in general, employ an ex-convict, while some state and territory governments may limit the time for or before which a former convict may be employed. Historical usage The particular use of the term "convict" in the English-speaking world was to describe the huge numbers of criminals, both male and female, who clogged British gaols in the 18th and early 19th century.

Java War
The Java War ( jv, ꦥꦼꦫꦁꦗꦮ) or Diponegoro War () was fought in central Java from 1825 to 1830, between the colonial Dutch Empire and native Javanese rebels. The war started as a rebellion led by Prince Diponegoro, a leading member of the Javanese aristocracy who had previously cooperated with the Dutch. The rebel forces laid siege to Yogyakarta, a move that prevented a quick victory. This gave the Dutch time to reinforce their army with colonial and European troops, allowing them to end the siege in 1825. After this defeat, the rebels continued fighting a guerrilla war for five years. The war ended in a Dutch victory, and Prince Diponegoro was invited to a peace conference. He was betrayed and captured. Due to the cost of the war, Dutch colonial authorities implemented major reforms throughout the Dutch East Indies to ensure the colonies remained profitable. History The direct cause of the Java War was the decision by the Dutch to build a road across a piece of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pirate
Piracy is an act of robbery or criminal violence by ship or boat-borne attackers upon another ship or a coastal area, typically with the goal of stealing cargo and other valuable goods. Those who conduct acts of piracy are called pirates, vessels used for piracy are pirate ships. The earliest documented instances of piracy were in the 14th century BC, when the Sea Peoples, a group of ocean raiders, attacked the ships of the Aegean and Mediterranean civilisations. Narrow channels which funnel shipping into predictable routes have long created opportunities for piracy, as well as for privateering and commerce raiding. Historic examples include the waters of Gibraltar, the Strait of Malacca, Madagascar, the Gulf of Aden, and the English Channel, whose geographic structures facilitated pirate attacks. The term ''piracy'' generally refers to maritime piracy, although the term has been generalized to refer to acts committed on land, in the air, on computer networks, and (in scien ...

Gresik Regency
Gresik Regency ( older spelling: Grissee, ) is a regency within East Java Province of Indonesia. As well as a large part of the Surabaya northern and western suburbs, it includes the offshore Bawean Island, some 125 km to the north of Java and Madura. The regency's administrative centre is the town of Gresik, about 25 km to the northwest of Surabaya. Gresik Regency (excluding Bawean Island) is also part of Gerbangkertosusila, the metropolitan region of Surabaya. Etymology Thomas Stamford Raffles in his book, The History of Java, reveals that the name of Gresik comes from the word ''Giri Gisik'', which means "mountain near the coast", referring to the hilly topography of the Gresik town center near the coast. History Since the 11th century, Gresik has become an international trade center visited by many nations such as, Chinese, Arabs, Champa, and Gujarat. Gresik Regency is also the first entry point for Islam in Java, which among others is marked by the existence of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bawean
Bawean ( id, Pulau Bawean) is an island of Indonesia located approximately north of Surabaya in the Java Sea, off the coast of Java. It is administered by Gresik Regency of East Java province. It is approximately in diameter and is circumnavigated by a single narrow road. Bawean is dominated by an extinct volcano at its center that rises to above sea level. Its population as of the 2010 Census was about 70,000 people, but more than 26,000 of the total (that is about 70% of the male population) were temporarily living outside, working in other parts of Indonesia, Singapore and Malaysia). As a result, females constituted about 77% of the actual population of the island, which is thus often referred to as "the Island of Women" ( id, Pulau Putri). The 2020 Census revealed a population of 80,289. The island territory is divided into two administrative districts, Sangkapura and Tambak. About 63% of the population (about 50,612 in 2020) live in the district of Sangkapura, centred o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
