An Eco-sustainable World
Nature to be saved



Sumatra is the sixth largest island on the planet, with an area of about 470,000 km² and is the third largest island in the Indonesian archipelago, after New Guinea and Borneo.

Etymology –
The etymology of the island of Sumatra is a matter of debate among scholars. The name “Sumatra” appears to derive from several ancient sources and languages.
One of the most accepted theories is that the name Sumatra comes from the Sanskrit language, an ancient sacred language of India. In Sanskrit, the word “Samudra” means “sea” or “ocean”, and Sumatra is surrounded by seas and oceans, so the name may refer to its geographical location. However, the evolution of the term from “Samudra” to “Sumatra” may have been influenced by other languages and cultures.
Other theories suggest that the name Sumatra comes from the Old Malay language or other local languages of Indonesia, but these theories are less common and less accepted than the Sanskrit origin.
Ultimately, the exact etymology of “Sumatra” may remain a mystery, as linguistic roots can be complex and influenced by many cultures and historical influences.

Geographic Features –
Sumatra is a large island located in the Indonesian archipelago in Southeast Asia. This large island is located west of the Malay peninsula and north of the island of Java. It is the sixth largest island in the world by area and is part of Indonesia, one of the largest countries in the world.
Sumatra is famous for its mountain range, which includes the Barisan Mountains, a series of volcanic mountain ranges. Mount Kerinci, located in Jambi province, is the highest mountain in Indonesia and the entire Malay archipelago, with an elevation of over 3,800 meters.
Due to its location along the Pacific Ring of Fire, Sumatra is home to several active volcanoes. One of the most famous volcanoes is Mount Sinabung, which has erupted several times in recent decades. Toba volcano, located in the north of the island, is known to be the site of the largest volcanic eruption in the last two million years.
The island is crossed by several rivers, including the Musi River, which flows through the city of Palembang in South Sumatra Province, and the Batang Hari River, one of the longest rivers on the island.
The coasts of Sumatra are characterized by vast coastal plains, many of which are suitable for agriculture and the cultivation of oil palms.
Sumatra is famous for its vast rainforests, which make up one of the richest biodiversity regions in the world. These forests are home to many unique plant and animal species, including the orangutan, Sumatran rhinoceros, Sumatran elephant, and Sumatran tiger.
The island of Sumatra has several lovely beaches on its western and eastern coasts. Some of the more popular beach resorts include Bukit Lawang, Pulau Weh and the Mentawai Islands.
Sumatra’s climate is predominantly tropical, with high temperatures and a rainy season from November to March. This region can experience heavy rains and floods during the rainy season.
Major cities in Sumatra include Medan, Palembang, Padang, and Bandar Lampung. Medan is the largest city on the island and serves as an important economic and commercial centre.
Overall, Sumatra is a fascinating and diverse island with impressive geography and a rich diversity of flora and fauna. Its natural beauty and ecological importance make it a unique destination for nature lovers and adventurers.

Historical Notes –
Sumatra has a history that has its roots in prehistoric times and therefore goes back thousands of years. Archaeological sites have been discovered which bear witness to human presence on the island since the Paleolithic period.
In the first millennium AD, Sumatra was part of the ancient kingdom of Srivijaya, which was one of the major maritime empires of Southeast Asia. Srivijaya was located in the region of present Palembang.
In the north of the island, the kingdom of Aceh (or Atjeh) emerged and became a powerful Islamic state in the 14th century. Aceh maintained its independence for a long time, resisting the Dutch until the late 19th century.
The Dutch subsequently began establishing their presence on the island in the 16th century and eventually subdued large parts of Sumatra. Indonesia, including Sumatra, remained a Dutch colony until World War II.
After World War II, Indonesia sought independence from the Dutch. The independence struggle began in 1945, and Sumatra was one of the key areas where this struggle took place.
Indonesia finally gained its independence in 1949, and Sumatra became part of the Republic of Indonesia. The island has contributed significantly to Indonesia’s economic and political growth.
Over the years, Sumatra has seen internal conflicts, such as the Free Aceh Movement (Gerakan Aceh Merdeka or GAM), which sought independence for the Aceh region. However, a peace agreement was reached in 2005 which ended the armed conflict.
In December 2004, Sumatra was hit by a devastating tsunami caused by an underwater earthquake. This tsunami claimed the lives of thousands of people in Indonesia and other countries in the region.
Sumatra is located on the Pacific Ring of Fire and is famous for its volcanic activity. Krakatoa volcano, located between Sumatra and Java, is best known for its 1883 eruption, one of the deadliest in history.

Ecosystem –
Sumatra’s ecosystem is one of the most diverse and interesting in Indonesia and the world. Sumatra is the sixth largest island in the world and is home to a diverse range of habitats, from tropical rainforest to swamps, mountains to seashores.
1. Tropical Rain Jungle:
– Sumatra’s rainforest is one of the oldest and most biodiverse on the planet.
– It is home to numerous species of animals, including orangutans, Sumatran tigers, elephants, Sumatran rhinos, and a variety of primates and exotic birds.
– This region is threatened by deforestation, mainly caused by land conversion for agriculture and industry.
2. Mountains and Montane Forests:
– The island has a mountain range, including the Barisan Mountains, running its length.
– These mountains are home to montane forest ecosystems with a rich diversity of plant and animal species adapted to cooler climates.
– The mountainous region is also the source of several rivers that flow through the island.
3. Swamps and Wetlands:
– Sumatra has vast swamps and wetlands, such as the Padang Marshes and Lake Toba.
– These areas are key to the conservation of many species of waterfowl and other aquatic creatures.
4. Coastal and Marine Ecosystems:
– The coasts of Sumatra are bordered by the Indian Ocean and are characterized by mangroves, beaches and coral reefs.
– These coastal ecosystems are important for marine biodiversity, including fish, sea turtles and other marine organisms.
5. Oil Palm Plantations:
– Sadly, many areas of Sumatra have been converted to oil palm plantations, which has led to severe deforestation problems and loss of natural habitats.
Sumatra’s ecosystem is plagued by significant threats, including deforestation, illegal hunting, and habitat loss from agricultural expansion. Preserving this outstanding natural heritage is crucial to preserving Sumatran’s unique biological diversity and protecting endangered species such as the Sumatran orangutan and Sumatran rhinoceros. Conservation efforts are ongoing, but much more needs to be done to ensure the survival of these precious ecosystems.

Flora –
Sumatra’s flora is exceptionally diverse due to its diverse geography, which includes mountains, rainforests, lowlands, and coasts.
Sumatra is home to some of the oldest and most biodiverse tropical rainforests in the world. These forests are rich in a diverse range of trees, epiphytic plants, lianas and orchids. Some notable trees include the dipterocarp (Dipterocarpaceae), which is a key component of the rainforests of Southeast Asia, and the durium (Durio), also known as the “smell fruit” or “king of fruits”, which is native of the island.
Oil palm is grown on a large scale in many parts of Sumatra for the extraction of palm oil, which is widely used in the food and cosmetic industries. However, the intensive cultivation of oil palm has led to environmental concerns, including deforestation and loss of wildlife habitat.
Sumatra is home to several nature reserves and national parks that preserve and protect its rich biodiversity. These parks include Gunung Leuser National Park, Bukit Barisan Selatan National Park, and Kerinci Seblat National Park. These areas are important for the conservation of endangered species such as the Sumatran orangutan and the Sumatran rhinoceros.
The flora of Sumatra also includes many plants traditionally used for medicinal purposes by the local communities. For example, Tongkat Ali root (Eurycoma longifolia) is known for its aphrodisiac properties and is grown in parts of Sumatra.
Many ornamental plants, including orchids and ferns, are grown in gardens and greenhouses around the world. Some of these plants may also be native to or grown in Sumatra.
Sumatra is also known for growing fruit trees such as durium, rambutan, mangosteen and cocoa. These tropical fruits are prized for their unique flavor and are consumed both locally and exported.
Sumatra’s flora is a treasure trove of biodiversity, but it is also threatened by environmental challenges such as deforestation, habitat loss and intensive agriculture. Therefore, the conservation of this rich biological diversity is vital to preserve the island’s unique ecosystem.
