Sugarcane (Saccharum officinarum)

Tebu or sugarcane (Saccharum officinarum) is a plant species in Poaceae, a large grass that grows strong, a sturdy stalk, rich in sucrose as a simple sugar that accumulates in the stem segment and is widely cultivated in the tropics for the production of sugar, ethanol and others.

S. officinarum has tall and broad stems, has no branches, grows upright, 3-5 meters high or more, has a waxy coating that is grayish white, especially on young stems. Each segment has a border where the leaves grow and has a bud which is commonly called the "budding eye".

Dlium Sugarcane (Saccharum officinarum)

Incomplete leaves consisting only of strands and midribs, sitting at the base of the segment, long strands of 1-2 meters long, 4-7 cm wide and pointed end. The midrib grows elongated and covers the vertebrae, attached to the stem in an intermittent sitting position and protects the buds.

Root fibers grow at the base of the stem, 0.5-1 meters long and only the tips of young roots have hairs to absorb nutrients. Sugarcane grows well with uniform rainfall until the age of 8 months and this need is reduced just before harvest.

Plants grow well in hot and humid climates, altitudes 5-500 m, temperatures 28-34C, humidity above 70%, fertile soil and enough water but not stagnant and pH 5-6. All stems contain sugar water to 20% content.

Indian rosewood (Dalbergia latifolia)

Sonokeling or Java palisandre or Indian rosewood ( Dalbergia latifolia ) is a species of plant in the Fabaceae, a large tree producing hardwood, medium weight and high quality, rounded leaves, thin and broad pods, highly adaptive, grows in dry and rocky landscapes with lots of sunlight. D. latifolia has medium to large size, cylindrical stems, up to 40 m high with a ring of up to 2 m, the bark is brownish gray and slightly cracked longitudinally. The crown is dense, dome-shaped and sheds leaves. The leaves are compound and pinnate oddly with 5-7 strands that have different sizes and appear alternately on the shaft. The leaves are round or elongated in width or heart, the upper surface is green and the surface is pale green. The flowers are small, 0.5-1 cm long and clustered in panicles. The pods are green to brown when ripe and are elongated lanceolate, pointed at the base and tip. The pods have 1-4 seeds which are soft and brownish. Indian rosewood grows at elevations below 600 m,

Evolution theory goes beyond

OPINION - As a Wallacean and Darwinian, I have always viewed life from the perspective of evolutionism. I see the world of plants and animals always using evolutionary theories. How a species develops functional organs, forms morphology, adapts to ecosystems and so on as a natural laws. This perspective ultimately forms my framework for thinking about various things, including the way I see myself, everyday problems and the way I think about big things such as economics, geopolitics, war and so on using an evolutionary perspective. Alfred Russel Wallace, Charles Darwin and Jean-Baptiste Lamarck are three great figures who really inspired me. They are well known as pioneers of evolutionary theories. They start from small things in the sub-subject of biology, although they also discuss geology and so on. Wallace focused on species adaptation and Darwin on sexual selection. Both developed evolutionary thinking using observational methods. Lamarck focused on structural morphology using l
