The Semeru volcano is an active volcano in Indonesia’s East Java province. In this region, the Indo-Australian plate subducts beneath the Eurasia plate. This is the tallest mountain on the island of Java. The name “Semeru” is derived from Meru, the Hindu world’s central mountain, or Sumeru, the home of the gods. This stratovolcano is also known as Mahameru, which means “Great Mountain” in Sanskrit. It is one of the most popular hiking destinations in Indonesia.

Semeru rises dramatically above the eastern Java coastal plains. Maars with crater lakes have formed in a line across the summit of the volcano. It formed south of the overlapping Ajek-ajek and Jambagan calderas. The eruption’s byproducts are andesitic. Semeru is the southernmost volcano in the Tengger Volcanic Complex. The eruptions of Semeru have a long history. At least 55 eruptions of lava flows and pyroclastic flows have been recorded since 1818. (11 of which resulted in fatalities).

Tumpak Sewu, also known as Coban Sewu, is a waterfall in East Java, Indonesia, located between the Pronojiwo District in the Lumajang Regency and the Ampelgading District in the Malang Regency. Semeru, Java’s highest mountain and an active volcano, obscures the waterfall. The waterfall’s primary water source is the Glidik River, which flows down Semeru. Tumpak Sewu roughly translates to “a thousand waterfalls” in Javanese. The name most likely refers to the appearance of multiple waterfalls in a single, semicircular area.

The Ijen volcano complex is a group of composite volcanoes in East Java, Indonesia, near the Banyuwangi and Bondowoso regencies. It is notable for its blue fire, acidic crater lake, and laborious sulfur mining.

The Arabica Coffee Garden Tourism object is owned by BUMN PT Perkebunan XXVI and spans 4,000 hectares and 900 meters above sea level. It is about 57 kilometers east of Bondowoso. The visitor can gaze out the window and take in the breathtaking scenery.

Sukamade beach is roughly 97 kilometers southwest of Banyuwangi. It is a beautiful, tranquil, natural setting that is part of the 50,000-hectare Meru Betiri National Park. Turtles lay eggs on Sukamade beach nearly every night of the year. Because the site is obviously of global importance, the overworked park rangers protect it 24 hours a day, 365 days a year.

The rangers take some eggs to protect them from human and animal predators. The eggs are incubated in the park’s hatchery before being released into the sea from the same beach where they were laid. There are other beaches within the park’s boundaries that are comparable, but the turtles appear to prefer Sukamade.
