Abstract

Penelitian ini bertujuan mengkarakterisasi gelatin tulang kaki ayam, kulit itik dan kulit babi serta membedakan profil asam lemak dari ketiga material tersebut. Metode yang digunakan: proses curing dan hidrolisis dengan variasi suhu. Hasil yang diperoleh dikarakteisasi dengan FTIR dan GC-MS. Hasil yang diperoleh menunjukkan gelatin yang dihasilkan dari tulang kaki ayam, kulit babi dan kulit itik pada suhu 80ᵒC masing-masing 2.02%; 9.33% dan 1.1%. Kadar air dari tulang kaki ayam, kulit babi, dan kulit itik yaitu 11.19%; 7.73% dan 7.7%. kadar air tersebut telah memenuhi standar kadar air SNI yaitu maksimum 16%. Hasil karakterisasi gelatin dengan FTIR  menunjukkan serapan gugus fungsi yang spesifik. Pada spektrum FTIR gelatin kulit babi terdapat gugus N−H dan O−H (3433,79 cm-1), CH2 (2931,01 cm-1), C═O (1655,21 cm-1), N−H dan C-N (1544,38 cm-1), N−H (1237,39 cm-1) dan gugus C−O (1079,69 cm-1). Peak yang dihasilkan kulit babi lebih sedikit. Sedangkan  GC-MS mampu membedakan komponen asam lemak babi dengan asam lemak ayam dan itik. Diperoleh hasil bahwa komposisi asam lemak utama pada lemak babi adalah asam oleat C18:1 (58,79%), stearat C18:0 (11,66%) dan palmitat C16:0 (11,44%). Komponen asam lemak utama pada lemak babi murni secara keseluruhan memiliki asam arakidonat dan asam eikosenat yang tidak terdeteksi pada lemak lain.

Abstract

Stylotella sp. sponge is a type of marine invertebrate animals that are widely distributed in Indonesian marine areas. One of the spreading areas of the Stylotella sp. sponge is in the Selayar Islands, South Sulawesi, Indonesia. Sponges have potential as a drug because they contain secondary metabolites. The aim study was to identify the types of secondary metabolite compounds and determine the bioactivity of Stylotella sp. compounds against MCF-7 breast cancer cells. The extraction method was used in the process of obtaining isolates because it is easy and economical. Testing the level of purity of isolates was carried out with three eluent systems which showed a single stain result. FTIR characterization results showed that pure isolates contained alkaloids which were characterized by the appearance of O-H, C-N, and C-H groups. The activity of MCF-7 cells using the colorimetric method showed an IC50 value of 14987.50 µg / mL, not toxic.

Abstract

Chicken egg shells contain an inorganic element (CaCO3) which has potency to be a source of calcium hydroxide (Ca(OH)2) which is then reacted with diammonium hydrogen phosphate ((NH4)2HPO4) as a phosphate precursor for hydroxyapatite synthesis. This study aims to determine the characterization of hydroxyapatite from eggshells and determine the absorbability of hydroxyapatite-gelatin composites against methylene blue. Synthesis of hydroxyapatite used precipitation method. The calcination results obtained calcium hydroxide (Ca(OH)2) content in the shell of 68.3%. Analysis of hydroxyapatite with Fourier Tranform Infra-Red (FT-IR) there was a wavenumber of 3434 cm-1 perform hydroxyl groups (-OH-), 1421 cm-1 carbonate groups (-CO3-2) and 1035 cm-1, 604 cm-1, 471 cm-1 phosphate groups (-PO4-2), and analysis by x-ray diffraction revealed that pure hydroxyapatite crystals had formed at an angle of 2Ɵ = 34,08 with crystallinity of 100%. The peaks that appear on the XRD diffractogram are adjusted to the Joint Committee on Power Diffraction Standards (JCPDS) No. 09-0432. The synthesis of HAp-gelatin composites obtained typical groups such as, amine groups from gelatin and phosphate groups and carbonates from Hap. The results of methylene blue absorption using hydroxyapatite-gelatin composites have obtained optimum conditions at a ratio of 2: 4 for 240 minutes with an efficiency of 63%. Based on these data, it reveals that the longer the time given, the greater the methylene blue absorbed
