The aim of the investigation is to obtain a good preparations of effervescent granules of ethanol extract of pepino fruit (Solanum muricatum Aiton) based on parameter of flowability and repose angle, density, moisture content, loss on drying and dispersibility. Maceration method and ethanol 96% as the solvent is use to obtain the extract of pepino fruit (Solanum muricatum Aiton). There are three formula design of effervescent granules formula 1,2 and 3 each of which in variation of  binder PVP K30 2%, 4% and 6% (w/w). The granules is obtain by wet granulation method in which ethanol extract of pepino fruit as the active ingredient. Results of evaluation showed that angle of repose  range from 33.425-34.352o while flowability range from 5.84-6.66 g/second. Bulk density range from 0.519-0.570 g/ml, tap density 0.552-0.53 g/ml, true density 0.2005-1.22 g/ml. Uji porositas berkisar 6.36-44.609 % while the dispersibility range from 1.407-1.477 gram/second. Based on the results can be concluded that all granules possess good properties pharmaceutically.

Over sunlight exposure in long periode may cause skin damage, premature aging, and skin cancer possibilitie. Sunsreen can protect the skin from negative effect of sunlight, it can reduce the negative effect of UV radiation. Seaweed powder Eucheuma cottonii. Doty is one of the sea plants that can be used as a sunscreen. The objective of this research was to evaluate the physical stability of cream seaweed powder (Eucheuma cotonii. Doty). Cream evaluation included organoleptic, pH, viscosity, freeze an thaw, and sentrifuge test. The organoleptic examination that has been done does not change the smell, color, fungal growth, and does not form a layer on the surface of the creams, and creams remain homogeneous. Emulsion type of preparation was the water in oil. The effect of storage time on viscosity creams are not significant changes. The result sentrifuge test at a speed of 3800 rpm for 5 hours showed the cream to remain stable, and there was no phase separation. Cream storage at two different temperatures or freeze thaw cycle was stable there were no phase separation until the cycle to six.

Seaweed (Eucheuma cottoni) is a marine biota that is often used as an additive to pharmaceutical products that function as thickener. But seaweed, which is rich in carrageenan, also contains vitamin C which has the potential as an antioxidant. The method used was to test the antioxidant activity of seaweed extract (Eucheuma cottoni) with the DPPH (1,1-Diphenyl-2-Picrylhdrazil) damping method. The test sample was in the form of seaweed ethyl acetate extract, where the standard standard of comparison of quarsetin and seaweed extract samples was made in 5 variations of concentration. The standard curve produced by quarsetin with concentrations of 2, 4, 6, 8, 10 ppm at the maximum wavelength DPPH 514,942 nm. The results obtained by the Kuarsetin standard with regression values y = 6.4765x + 7.567, the correlation value r = 0.99959 and IC50 = 6.48 (very strong antioxidant activity) while the ethyl acetate extract of seaweed with concentrations of 600, 800, 1000, 1200, 1400 ppm % inhibition was obtained with regression values y = 0.0104x + 16.708, the correlation value r = 0.9972 and IC50 = 3201.15 (very weak antioxidants). So it can be concluded that the seaweed ethyl acetate extract has the potential for antioxidant activity.
