Applied two preparations of alginite formed from natural bituminous rock alginite in 4 different variants into the soil (granular forms) and spraying on leaves (extracts) in 2 cultivars of Solanum lycoper-sicum L. resulted in reduced production traits on plants and fruits, increased or decreased accumulation of macro and microelements content in plants and fruits and by increasing the antioxidant activity of the fruits compared to the control variant without alginite.

Solanum Lycopersicum L

Free radicals can cause damage to human skin, so antioxidants are needed to counteract the negative effects of these free radicals, for example preparations in the form of face masks. For tomatoes (Solanum lycopersicum L.) contains nutritious substances, namely lycopene which can be useful as an antioxidant in the skin. This study aims to determine the effect of variations in kaolin and bentonite bases on physical characteristics and antioxidant activity of tomato lycopene extract clay mask, and to determine the best formula. Tomato lycopene extract (Solanum lycopersicum L.) was modified into a microemulsion preparation to keep antioxidant activity stable. Kaolin and bentonite which were used as bases had various concentrations in each formula, namely F1 15% and 2%, F2 20% and 1.5%, F3 25% and 1%, F4 30% and 0.5%, respectively. The results showed that the four clay mask preparations were homogeneous and did not change in color, shape and aroma. The pH test on the four formulas is F1 4.33 ± 0.35, F2 5.58 ± 0.24, F3 6.48 ± 0.22, F4 7.34 ± 0.08. The viscosity test on the four formulas, namely F1 20213.3 ± 140.4, F2 24133.3 ± 83.26, F3 29080 ± 105.83, F4 33293.3 ± 378.06. The spreadability test was F1 6.59 ± 0.24, F2 5.59 ± 0.16, F3 4.85 ± 0.11, F4 7.84 ± 0.05. The test time for the preparation to dry was F1 19.02 ± 0.36, F2 15.33 ± 0.54, F3 11.27 ± 0.42, F4 8.24 ± 0.50. Easy-to-clean tests i.e. F1 and F2 are very easy to clean, F3 and F4 are easy to clean. The best formula for clay masks is the F3 preparation where the concentration of kaolin is 25% and bentonite is 1%.

Research on the antioxidant lycopene of tomato fruit (Solanum lycopersicum L.) blended in frying fat from catfish (Clarias sp) oil has been done. The purpose of this research is to determine the antioxidant activity of tomato lycopene before and after being grounded into frying fat and determine the quality of frying fat after being grounded with tomato lycopene. The antioxidant activity of tomato lycopene is determined by the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Analysis of frying fat quality includes determination of pH, determination of FFA (free fatty acid) levels, determination of total fat content, measurement of water content, peroxide number and organoleptic observation. Antioxidant activity of tomato lycopen was very high, namely with inhibition value of 89.79%; 90.34%; 91.49% and 92.10%. Frying fat analysis showed high antioxidant activity of lycopene tomatoes with 50.67% inhibition; 51.63%; 51.39% and 51.23%. The results of the analysis of the quality of frying fat are nearly same with SNI quality standards, except for peroxide numbers. Keywords: tomato, lycopene, antioxidants, frying fat, catfish, DPPH
