Reconstructed Human Epidermis (RHE) is an artificial epidermis made in such a way that it resembles human skin, and can be used for the identification of irritant chemicals, especially for cosmetic and topical medicinal products. Currently the new RHE is produced by European and American countries, whose skin physiology is very different from Indonesia. Based on this, the Center for Research on Drugs and Food, NADFC of Republic of Indonesia took the initiative to develop the reconstruction of keratinocyte, melanocytes and fibroblasts cells into RHE adapted to the anatomical and physiological functions of the skin of Indonesians. RHE is made from an epidermal layer composed of keratinocyte and melanocytes cells that are reconstructed with a dermis layer composed of fibroblast and collagen cells. Keratinocyte, melanocytes and fibroblasts cells are cultured on suitable mediums by adding a suitable growth medium. To find out that RHE has been successfully reconstructed, measured percentage of cell life, made histology preparation to see the existence of cell nucleus, and conducted Immunohistochemical examination to see existence of integration (bond) between antigen. From the research results can be seen that keratinocyte cells grown on culture medium Keratinocyte SFM (IX) with rEGF supplements; melanocyte cells grown on Melanocyte 254 culture medium with HMGS supplementation; and fibroblast cells grown on Fibroblast M 106 culture medium with LSGS supplementation. The percentage of epidermal cell life grew well in the planting of 10 � 104 cells /mL keratinocytes and 0.25 � 104 cells /mL of melanocyte cells and survived until the 11th day with live cell percentage of 93.45%. In making preparation for histology with HE staining, there is a cell life in RHE tissue. Used Immunohistochemical (IHC) examination using cytokeratin 10 antibody marker to view physiological function of epidermal tissue.

Papaya seed in previous research is known has an effect of anthelmintic on Ascardia galli, but the effect of papaya seed just by traditional method i.e. boiling in water. To get the effective extraction methods, it still needs to be done many kinds of extraction methods of papaya seed, to know which one is the best. Methods of extraction in this research were maceration, soxhletation, and ultrasonic digestion. We used two kinds of papaya seed: wet and dry, using solvent: water, 70% ethanol, and n-hexane. Data of anthelmintic activity were percentage of worm death, LD50, and relative potential to pyrantel pamoate as positive control. The result showed that the best extraction method of papaya seed which had highest in vitro effect on Ascardia galli worm was maceration method with 70% ethanol as solvent of wet papaja seed. It killed 60% of worm with LD50 9.36 mg and its relative potential is 0.66 times pyrantel pamoate.

Turmeric is one of the plants that can be used as traditional medicine. To improve the quality of turmeric as a traditional medicine, turmeric must be free from contamination of pesticide residues, aflatoxin, pathogen bacteria, and curcumin content contained therein. The aim of this research was to investigate the contamination of endosulfan and malathion pesticides, aflatoxin B1, Escherichia coli microbial contamination, Salmonella sp., Staphylococcus aureus and Pseudomonas aeruginosa, as well as to know the content of curcumin contained in turmeric rhizomes. The sample in this research was taken from Wonogiri region of Central Java, Indonesia by random sampling. The methods used were HPLC for Aflatoxin B1 analysis and curcumin and Gas Chromatography for residual pesticide analysis of Endosulfan and Malathion pesticides. Microbial testing included the establishment of Total Plate Count, AKK, MPN Coliform, and analysis of Escherichia coli microbial contamination, Salmonella sp., Staphylococcus aureus and Pseudomonas aeruginosa. The results showed that the samples were not contaminated by Aflatoxin B1 and Endosulfan pesticides, but contained a residual malathion with levels of 0.014 mg/kg. Microbial test results showed that the turmeric samples from the Wonogiri market did not meet the quality requirements due to contamination of Salmonella sp. and the chopped AKK exceeded the specified limits.

Lozenges require the tablet hardness of 7-14 Kgf to be a suitable binder. Gelatine can be used to meet the requirement as it creates granules with bad flow time. PVP produces granules with better flow time but it takes a large quantity to reach the lozenges hardness desired. This study aimed to determine the effect of the concentration ratio of gelatine and PVP as binders on the physical properties of red-ginger extract lozenges. Lozenges made employing the wet granulation method following the ratio of gelatine and PVP of 1:1, 1:2, 1:3, 1:4 and 1:5. The hardness test results of the formula 1 to 5 are 9, 14, 16, 13 and 12 Kgf respectively and the friability test results were 0,4%, 0,7%, 0,2%, 0,3% and 0,6% accordingly. The combination of gelatine and PVP as binders provide a significant difference in the hardness and friability of the tablets.
