The Sweet Potato originates from tropical regions such as South America and Papua (which is still debated). Those who disagree with the Papuan origin argue that Native Americans (Indian people) sailed westward across the Pacific Ocean, helping to spread the sweet potato to Asia. This proposal is widely opposed as it contradicts climatological and anthropological facts.

Sweet potato plants require hot and humid air. The most ideal area for sweet potato cultivation is one with a temperature of 21–27

 C. Areas that receive 11–12 hours of sunlight per day are preferred. Optimal growth and production for sweet potato farming are achieved during the dry season (kemarau). In dry land (tegalan), the best planting time for sweet potatoes is during the rainy season, while in paddy fields, the best planting time is after the rice crop is harvested. Sweet potato plants can be grown in areas with rainfall of 500–5,000 mm/year, with the optimum range being between 750–1,500 mm/year.

• Root and Tuber (Akar dan Umbi) The roots have formed into tubers, and the numerous contents within them make this part widely utilized. Sizes vary, being long or short, with a large to medium diameter. Tuber color is determined by the species, including purple, yellow, orange, and white.

• Stem (Batang) The stem is cylindrical in shape, grows creeping (trailing) and erect, is branched, and is usually green, brown, or purple in color.

• Leaves (Daun) Rounded, with entire margins (tepi rata), pointed tips (runcing), and resemble a heart (jantung), but some types have a palmate (menjari) leaf shape. The leaves are stalked (petiolate) and have a length of 4–20 cm. The color is generally green.

• Flower (Bunga) Resembles a trumpet, composed of 5 petals (mahkota), then 5 sepals (daun bunga), and only one pistil stalk.

• Propagation is done generatively (seeds) or vegetatively (stem and shoot cuttings).

Flavonoids, polyphenols, pelargonidin, peonidin, cyanidin, malvidin, petunidin, and delphinidin. Other beneficial compounds in purple sweet potatoes include phenols, which are chemical compounds that have anti-aging effects and antioxidant components.
