Temulawak (Curcuma zanthorrhiza)

Temulawak or Java ginger or Javanese ginger or Javanese turmeric or Curcuma xanthorrhiza (Curcuma zanthorrhiza) is a plant species in Zingiberaceae, grows well in loose soil in tropical forests in the lowlands to an altitude of 1500 meters above sea level and tubers are used for medicinal herbs and drinks.

C. zanthorrhiza has pseudo stems up to 2 m tall. The stem is a midrib of upright, overlapping leaves, green or dark brown in color. Rhizomes are perfectly formed, large, branched and reddish brown, dark yellow or dark green.

Dlium Temulawak (Curcuma zanthorrhiza)

Each bud forms 2-9 leaves with a circular shape extending to lancet, green or light purple to dark brown, leaves 31-84 cm long and 10-18 cm wide, stems 43-80 cm long and each strand is connected with a midrib.

Flowers are dark yellow, uniquely shaped and clustered with lateral inflorescences. The stems and scales are in the form of lines, 9-23cm long and 4-6cm wide, having protectors with comparable crowns. Petals are white, hairy and 8-13mm long.

The crown is tubular, 4-5cm long, long, round white flower strands with a red tip, 1-2cm long and 1cm wide, while the rhizome is dark orange or brown, with a pungent aroma and bitter taste.

Rhizome contains 48-59.64% starch, 1.6-2.2% curcumin and 1.48-1.63% essential oils which are believed to improve kidney work, anti-inflammatory, acne medications, increase appetite, anti-cholesterol, anemia, antioxidants, cancer prevention, and anti-microbial.



Vegetative propagation using old rhizomes aged 9 months or more, then germinated in a damp, dark place for 2-3 weeks. Another way is to cut old rhizomes that are harvested and already have buds, then dried for 4-6 days.

Wild temu lawak grows in shady lands, temperatures of 19-30C and rainfall of 1,000-4,000 mm/year. In general, this plant has a high adaptability for various weather conditions in tropical climates. Roots adapt well to various types of soil including calcareous, sandy and clay soils.

C. zanthorrhiza grows at an altitude of 5-1000 m, but the highest starch content in the rhizome is at an altitude of 240 m. Curcuma is planted in the highlands to produce rhizomes that contain only a little essential oil. Pests include Chrysodeixis chalcites, Agrotis ypsilon and Mimegrala coerulenfrons.

The main content of rhizomes is protein, carbohydrates and essential oils consisting of camphor, glucoside, turmerol, and curcumin which are useful as anti-inflammatory and anti-hepototoxic properties. Pharmacological effects include hepatoprotector, lower cholesterol, laxative, diuretic, relieve joint pain, increase appetite, smooth milk, and cleanse the blood.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Javan mocca or Javan slender caesar (Amanita javanica)

OPINION - Javan mocca or Javan slender caesar ( Amanita javanica ) is a mysterious fungus species and has been enigmatic since it was first reported by Boedijn in 1951 and after that no explanation or reporting of specimens is believed to be the same as expected. Boedijn (1951) described A. javanica which grew on Java island as having the characteristics covered in the Amanita genus. Corner and Bas in 1962 tried to describe Javan mocca and all species in Amanita based on specimens in Singapore. Over time some reports say that they have found A. javanica specimens in other Southeast Asia including also China, Japan, India and Nepal. But there is no definitive knowledge and many doubt whether the specimen is the same as described by Boedijn (1951). I was fortunate to have seen this species one afternoon and soon I took out a camera for some shots. In fact, I've only met this mushroom species once. Javan mocca is an endangered species and I have never seen in my experience in...

Gunung Sewu Geopark

Gunung Sewu Geopark or Gunung Sewu UNESCO Global Geopark or Pegunungan Sewu (Thousand mountains) are elongated mountains in Kulonprogo Regency, Bantul Regency and Gunung Kidul Regency in Yogyakarta Province, Wonogiri Regency in Central Java Province, to Tulungagung Regency in East Java Province on Java Island, Indonesia. The uniqueness of the ecosystem encourages the International Union of Speleology to propose the Sewu Mountains Karst Area into one of the world's natural heritages in 1993. On September 19 2015, UNESCO announced Gunung Sewu as the Global Geopark Network. Sewu Mountain is rich in biodiversity, archeology, history and cultural aspects. The Pacitan rock culture represents Paleolithic to Neolithic artifacts in Southeast Asia. About 1,802 square kilometers of the area contain traces of prehistoric settlements. Some prehistoric people lived in caves, while others lived in open spaces. Characteristics Gunung Sewu is a classic tropical karst landscape and is domin...
