ABSTRAK
Telah dilakukan penelitian mengenai penyediaan dan karakterisasi kitosan dari kulit udang lipan (Squilla mantis) sebagai adsorben untuk menurunkan kadar kolesterol. Kitosan diperoleh melalui proses deasetilasi kitin. Kitosan yang diperoleh digunakan sebagai adsorben untuk menurunkan kadar kolesterol, dengan cara menambahakan kitosan dengan variasi massa sebanyak 1, 3, 5 dan 7 gram ke dalam hasil ekstraksi lemak dan dengan variasi waktu perendaman 15, 30, 45 dan 60 menit. Besarnya kadar kolesterol dianalisis dengan menggunakan metode Kromatografi Gas (KG). Hasil penelitian menunjukkan bahwa dengan penambahan 1 gram kitosan , kadar kolesterol akan menurun sebesar 12,43%; 19,28%; 25,57% dan 32,94%. Pada penambahan 3 gram kitosan, kadar kolesterol akan menurun sebesar 14,37%; 25,46%; 32,18% dan 37,54%. Dengan penambahan 5 gram kitosan , kadar kolesterol akan menurun sebesar 32,89%; 36,12%; 42,46% dan 48,57%. Dan dengan penambahan 7 gram kitosan, kadar kolesterol akan menurun sebesar 28,75%; 32,54%; 35,23% dan 37,48%.

THE PREPARATION AND CHARACTERIZATION OF CHITOSAN FROM MANTIS SHELL (Squilla mantis) AS AN ADSORBENT
TO DECREASE CONCENTRATION OF CHOLESTEROL
ABSTRACT
A research about the manufacture and characterization of chitosan from mantis shells (Callinectes Sapidus) as an adsorbent to decrease concentration of cholesterol has been studied. Chitosan is obtained through the deacetylation process of chitin. That chitosan used as adsorbent to decrease concentration of cholesterol by adding chitosan with the variation of mass 1, 3, 5 and 7 grams into the result extraction of fat and with the variation of immersion time 15, 30, 45 and 60 minutes. The concentration of cholesterol are analyzed by using Gas Chromatography (GC). The result of research show that by adding 1 gram chitosan, concentration of chitosan decreased 12,43%; 19,28%; 25,57% and 32,94% respectively. In addition 3 grams chitosan, concentration of cholesterol decreased 14,37%; 25,46%; 32,18% and 37,54% respectively. By adding 5 grams chitosan, concentration of cholesterol decreased 32,89%; 36,12%; 42,46% and 48,57% respectively. And by adding 7 grams chitosan, concentration of cholesterol decreased 28,75%; 32,54%; 35,23% and 37,48% resperctively.
