Coffee (Coffea arabica)

Kopi gunung or mountain coffee or arabica coffee (Coffea arabica) is a plant species in Rubacea, up to 9 meters high, growing at an altitude above 700 meters above sea level, one of the most economically valuable plantation commodities among other plants.

C. arabica generally blooms after 2 years of age. Adult flowers pollinate with the opening of the petals and crown that will develop into fruit. Green skin will turn yellow and dark red with maturation. The entire process to harvest takes 6-8 months.

Flowers bloom at the beginning of the dry season and the fruit is ready to be picked at the end of the dry season. Primary branches will elongate and form new leaves at the beginning of the rainy season and prepare to produce flowers at the beginning of the upcoming dry season. The main stem has segments where a pair of opposite leaves grow.

Leaves have a line in the middle and lines to the side following the bone, wavy, thick green, muscular and tapered at the tip. The leaves grow and are arranged side by side in the armpits of branches and twigs. A pair of leaves is located in the same plane in the stem and twigs that grow horizontally.

Flowers are arranged in groups, each 4-6 buds and each leaf armpit produces 2-3 flower groups. The crown is white and fragrant. Green petals, base covering the ovaries containing two ovules. Stamens consist of 5-7 short stems.

The fruit has a length of 12-18 mm, light green then turns dark green, yellow, red and dark red to ripen. The fruit consists of exocarp, mesocarp, endocarp, epidermis and seeds. Old Mesokarp will be slimy and sweet. Mature seeds are white and hard.









Many varieties of arabica coffee are developed in the world to suit certain environments. The Indonesian Coffee and Cocoa Research Center recommends six varieties: Kartika 1 (1.8 tons/ha), Kartika 2 (1.9 tons/ha), Abesiania 3 (0.7 tons/ha), S795 (1.2 tons/ha), USDA 762 (1.2 tons/ha) and Andungsari 1 (1.9 tons/ha).

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 ...

Purhepecha oak (Quercus purhepecha), new species of shrub oak endemic to the state of Michoacán, Mexico

NEWS - In Mexico, several Quercus shrubby species are taxonomically very problematic including 8 taxa with similar characteristics. Now researchers report the purhepecha oak ( Quercus purhepecha De Luna-Bonilla, S. Valencia & Coombes sp. nov.) as a new tomentose shrubby white oak species with a distribution only in the Cuitzeo basin in the Trans-Mexican Volcanic Belt (TMVB). Quercus Linnaeus (1753) subdivided into 2 subgenera and 8 sections of which section Quercus (white oaks) has the widest distribution in the Americas, Asia and Europe. This section is very diverse in Mexico and Central America with phylogenomic evidence indicating recent and accelerated speciation in these regions. The number of shrubby oak species in Mexico is still uncertain. De Luna-Bonilla of the Universidad Nacional Autónoma de México and colleagues found at least 3 taxa in the TMVB, specifically Quercus frutex Trelease (1924), Quercus microphylla Née (1801) and Quercus repanda Bonpland (1809). In 2016,...

Cempaki (Termitomyces microcarpus)

Cempaki ( Termitomyces microcarpus ) is a species of fungus in the Lyophyllaceae family. It grows wild in tropical Asian forests near termite nests. It is rarely reported in urban areas. It is edible and known for its deliciousness, high nutritional value, and difficulty in cultivating. In Indonesia, it is used as an alternative food ingredient. T. microcarpus is the smallest of the Termitomyces species, umbrella-shaped, plain white, measuring 5 cm tall and 2.5 cm wide. It grows in dense clusters on surfaces and forms a mutualistic relationship, requiring the metabolic activity of termites as a substrate for growth. This species is known for its deliciousness, rich in nutrients, and has potential bioactive properties, such as helping lower cholesterol and acting as a tonic. Currently, it is difficult to cultivate on a large scale, and people rely solely on wild harvests. This mushroom is highly favored for its savory, delicious flavor and soft, chewy texture. It is often stir-fried ...
