PENGARUH VARIASI JENIS ASAM TERHADAP RENDEMEN GELATIN DARI TULANG IKAN CAKALANG (Katsuwonus pelamis)

The research about “The Effect of Variation of the Type of Acid on Gelatine Yield from Cakalang Fish Bone ( Katsuwonus pelamis )”. The aim of this research was to determine the higher gelatine rendament using various of type of acid. This research used Completely Randomized Design (CRD), each treatment was done in duplo. The acid variation in this research were Chloride, Sulphate, Phosphoric, Acetic, Oxalate and Citrate acid respectively. The result showed that the highest rendament was 14,658% at 5% of phosphoric acid. The analysis of the treatment has fulfilled the standard. Keywords : Gelatine, Cakalang fish bone, Isolate, Yield

APLIKASI KULIT PISANG KEPOK (Musa paradisiaca formatypica) SEBAGAI ADSORBEN ION MERKURI (Hg)

ABSTRAC T The study aims are to determine the influence of the best of smooth and the best of volume eluent of the concentration of ion mercury (II) the colomn with the flow from top to bottom. These are used has a diameter 1 cm, height 35 cm and adsorbent 5 g. The variations upon the smooth which is used 10, 20 and 30 mL/minute ad the volume of eluent 10, 50, 100 and 150 mL with a concentration 60 mg/L at pH 5. This study is using random the factorial, each treatment done as much as two times. From the results showed that the best of smooth be achieved in the smooth 10 mL/minute and the best of volume eluent be achieved in the volume of 150 mL in adsorption of ion mercury (II).
