Haustorium kelapa (Cocos nucifera L.) merupakan bagian dari tumbuhan kelapa yang
terbentuk selama tahap awal pertumbuhannya. Haustorium kelapa memiliki potensi
sebagai sumber nutrisi dan komponen bioaktif yang dapat memberikan manfaat
terapetik. Penelitian ini bertujuan untuk mengetahui kadar karbohidrat dan komposisi
karbohidrat (gula pereduksi, pati, amilosa, amilopektin, monosakarida dan disakarida)
pada haustorium kelapa. Kadar gula pereduksi, pati, amilosa, amilopektin dan serat
dianalisis dengan metode gravimetri dan spektrofotometri, sedangkan komposisi gula
(glukosa, fruktosa, sukrosa, dan maltosa) dianalisis dengan High Pressure Liquid
Chromatography (HPLC). Hasil penelitian menunjukkan % yield tepung haustorium
kelapa adalah 0,16%. Komposisi proksimat haustorium kelapa meliputi kadar air, abu,
lipid, protein dan karbohidrat berturut-turut sebesar 15,07%, 7,79%, 11,55%, 6,37%
dan 74,35%. Komposisi karbohidrat haustorium kelapa meliputi kadar gula pereduksi,
pati, amilosa, amilopektin dan serat berturut-turut adalah 17,87%, 25,35%, 4,98%,
20,36% dan 12,91%. Komposisi gula haustorium kelapa meliputi glukosa, fruktosa,
sukrosa dan maltosa berturut-turut adalah 7,02%, 6,65%, 10,0% dan 0,79%.
Haustorium kelapa mengandung karbohidrat dalam jumlah yang tinggi, sehingga
berpotensi menjadi alternatif bahan pangan sumber energi.

Coconut (Cocos nucifera L.) haustorium is a part of the coconut plant that forms during the early stages of its growth. Coconut haustorium has potential as a source of nutrients and bioactive components that can provide therapeutic benefits. This study aims to determine the carbohydrate levels and carbohydrate composition (reducing sugars, starch, amylose, amylopectin, monosaccharides and disaccharides) in coconut haustorium samples. Reducing sugar, starch, amylose, amylopectin and crude fiber content were analyzed using gravimetric and spectrophotometric methods, while the sugar composition (glucose, fructose, sucrose and maltose) was analyzed using an High Pressure Liquid Chromatography (HPLC) instrument. The results showed that the % yield of coconut haustorium flour is 0.16%. Proximate composition of coconut haustorium included water, ash, fat, protein and carbohydrate content of 15.07%, 7,79%, 11.55%, 6.37% dan 74.35% respectively. The carbohydrate composition of coconut haustorium includes reducing sugar, starch, amylose, amylopectin and fiber levels respectively 17.87%, 25.35%, 4.98%, 20.36% and 12.91%. Respectively the composition of coconut haustorium sugar includes glucose, fructose, sucrose and maltose 7.02%, 6.65%, 10.0% and 0.79%. Coconut haustorium contains a relatively high amount of carbohydrates, this has the potential to be an alternative food sourcept energy.
