These diverse names also show the existence of various cultivars which are reflected in the different forms of fruit and trees.

The main producing countries of duku are Malaysia, Thailand, the Philippines and Indonesia. But generally my money is consumed in each country, except for a few that are exported to Singapore and Hong Kong. Duku hasn't penetrated the fruit market in Europe and America.

     Distribution and local names

The area of ​​origin of duku stretches from around Siam, the Malay Land Peninsula to Borneo in the east, including the Philippines. In these areas, duku is planted as one of the important fruits. Even wild varieties or those that travel far can be found in nature. Now duku is also cultivated, though not large, in Vietnam, Burma, Sri Lanka, India, Australia, Hawaii, Suriname and Puerto Rico.

Duku is known by many names, such as langsat, langseh, langsep, lansa (Mal.); lansones, lanzone, lanzon, and fruits, (Fil.); langsad, longkong (Thailand); bill and bn bill (Vietnam); langsak, duku (Burma); and Gadu Guda (Sri Lanka). In English it is also called langsat and duku.


Medium-sized trees, with a height of up to 30 m and echoing up to 75 cm. Stems are usually grooved in an irregular manner, with flat buttress (root boards) protruding above the ground. Pepagan (bark) is gray with dark spots and orange, containing sticky, thick-colored sap (resin).

Odd, bare or downy pinnate compound leaves, with 6-9 children leaves arranged alternately, children of elliptical leaves (elliptic) to oval, 9-21 cm × 5-10 cm, glossy on the top side, like hides, with pointed base and the tip is short (tapered), the child leaves 5-12 mm.

Flowers are located in bunches that appear on large stems or branches, hanging, alone or in bundles of 2-5 bunches or more, often branching at the base, 10-30 cm long, hairy. Small flowers, sitting or short-stemmed, lonely, two-person. 5-cup-shaped cup-shaped petals, fleshy, greenish yellow. Round egg crown, erect, fleshy, 2-3 mm × 4-5 mm, white to pale yellow.

Propagation of duku which is done using seeds results in the slow growth of the fruiting plant. New plants flower at the age of 10 to 15 years. This plant germination has polyembryonic behavior (one seed produces many embryos or seedlings): one fertilized embryo, and the remaining apomicik embryo. Apomicik embryos develop from a network of parent trees so that their offspring have similar characteristics to their parents. Recalcitrant seeds, storing more than seven days will cause a rapid decline in sprouting power. Vegetative propagation is done by grafting and topping.


Duku varies greatly in the properties of trees and fruit; so there are also experts who separate it into different types (species). On the outline, there are two large groups of these fruits, which are known as duku, and which are called langsat. Then there was a mixed group between the two called duku-langsat, and the last group in Indonesia known as kokosan.

The group known as duku (L. domesticum var. Duku) generally has a tree with a large headline, dense with bright green leaves, with relatively short bunches and containing little fruit. The fruit granules are large, tend to be round, slightly thick-skinned but tend not to gummy when ripe, generally with small seeds and thick flesh, sweet or sour, and smell nice.
The group known as duku

Langsat (L. domesticum var. Domesticum) mostly has thinner, less bushy trees that are dark green, with upright branches. The fruit bunches are long, densely packed with 15-25 eggs that are oval and large. Langsat fruit is thin-skinned and always gummy (white) even though it is ripe. The flesh is a lot of juicy, sweet and refreshing sour taste. Unlike duku, langsat is not a fruit that can last long after picking. Within three days after being picked, the skin will turn black even if it does not damage the sweet taste. It's just that it looks unattractive.

Kokosan (L. domesticum var. Aquaeum) is distinguished by its hairy leaves, the sign full of crusty fruit grains that are very tightly packed, and the skin of the fruit is dark yellow. The fruit grains are generally small, thin-skinned and slightly gummy, but hard to peel. So that the fruit is eaten by being bitten and sucked by the liquid and the seeds (hence called cocoa), or massaged so that the skin breaks and the seeds come out (hence the name pisitan, pijetan, bijitan). With relatively large seeds and thin flesh, cocoa generally feels sour until very sour.

The most famous duku cultivar in Indonesia is duku palembang, mainly because of its sweet taste and little seeds. Actually, the main producer of duku is not the city of Palembang, but the Komering area (OKU and OKI regencies) as well as several other adjacent areas in South Sumatra. Another place that also produced it was the Kumpeh area, Muaro Jambi, Jambi. Duku from these regions is marketed to various regions in Sumatra and Java, and even exported.

Beside duku palembang, various regions also produce their own shaman. In Java, some of the locally famous are duku condet (formerly duku menteng and duku depok) from around Jakarta; duku papongan from Tegal; duku kalikajar from Purbalingga; duku karangkajen and duku klaten from Yogyakarta; duku matesih from Karanganyar; duku woro from Rembang; duku source from Kudus, and others. In South Kalimantan, it is known duku Padang Batung from Hulu Sungai Selatan District.

Given the durability of the fruit which is not like duku, langsat is generally known more limitedly and locally. Some popular cultivars, including singosari langsep from Malang, langsat tanjung from South Kalimantan, langsat punggur from West Kalimantan, and so on. From Thailand it is known as Langsat Uttaradit, and from Luzon, Philippines, known as Langsat Paete.

Duku is usually propagated by seed, which is intentionally sown or by collecting seedlings which grow spontaneously under the mother tree. But waiting for this new tree to produce, takes a long time (20-25 years) and it is not certain the quality is the same as the parent.

Another popular method is to transplant it. Although this grafting process takes a relatively long time (8-9 months, roots come out after 134 days), but new grafted trees can bear fruit at around two years of age. The disadvantage is that the percentage of grafted dead babies is quite large. After all, the growth is not strong.

What is Duku Fruit? - Modern propagation which is now mostly done is by grafting. This technique allows the trunk's genetic traits to produce the same as the parent, while the waiting time is shortened to 5-6 years. The shoots from the shoot are also stronger than the grafted tillers.
