Abstract

Introduction: Burns are injuries that caused by contact with a heat source. The natural alternative burn treatment can use hydrolyzed collagen derived from aquatic ecosystems, one of them is fish.Objectives: The aim of this research was to find the optimum formulation of tilapia fish collagen extract ointment.Methods: Fish skin that has been separated was prepared using the solution of NaOH 0,1 N and Butyl Alcohol 10%.Then the fish skin was extracted using a 0.5 M acetic acid solution and precipitated with a 0.9 M NaCl solution. Then, dialysis was performed using a plastic membrane (14 KDa) in a 0.1 M acetic acid solution and distilled water to obtain a wet collagen extract which was then in the FreezeDryer to reduce the water content.Results: The collagen extract obtained was used for ointment formulations with different concentrations of collagen extract, that is 5%, 10%, and 15% and 2 additional miana plant extracts were used with collagen extract 5+5% and 10+10%. The results of the formulation were tested on burns with a diameter of 0.715 cm in mice.Conclusion: From the results of the effectiveness test, the formulation with 15% collagen extract showed effective results. Indicated by the rate of wound healing in mice observations

Abstract

Hydrotalcite (HT) is a type of clay mineral belonging to the group of layered double hydroxides (LDHs) or anionic clays, which has a layered structure like brucite (Mg(OH)₂), but some of the divalent cations (such as Mg²⁺) are replaced by trivalent cations (such as Al³⁺). HT as a heterogeneous catalyst is particularly attractive because it is easy to separate and resistant to high temperatures. HT as a catalyst can be used in hydrocracking reaction to produce biofuel. Metal impregnation on HT is very promising to enhance catalytic activity especially with the bifunctional mechanism of catalyst. Ni-V metal impregnation has been successfully carried out on HTc using wet impregnation method which is indicated by the results of X-Ray Diffraction (XRD) which shows the emergence of typical peaks of both metals and HTc in 2θ = 35‒70⁰ for HTc, 2θ = 37.22⁰ (NiO) and 37.35⁰ (V2O5) regions, 2θ = 43.58⁰ for NiO, 2θ = 61.26⁰ (V) and 63.07⁰ (Ini). Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX) show a shape that is consistent with the characteristics of HT, namely the shape of the particles layered overlapping each other. In addition, the particle size of HTc is quite small with a scale of 1 μm indicating a particle size of hundreds of nanometers. EDX mapping shows that Ni and V have been dispersed evenly on the HTc surface. Based on the results of N2 adsorption-desorption isotherms, it shows that mesopores are formed which are characterized by hysteresis loops. Ni-V metal impregnation increases the surface area up to 19.915 m2/g and the pore diameter up to 37,642 nm. The results of the Waste Cooking Oil (WCO) hydrocraking reaction show that Ni-V metal impregnation can reduce the carboxylic acid composition up to 67.81% and increase hydrocarbons up to 15% at 10% Ni-V/HTc 1:2.
