The purpose of this study was to determine the effect of dragon fruit peel extract (Hylocereus polyrhizus) on the characteristics of turmeric cream and tamarind leaves. The concentration of dragon fruit peel extract treatment consisted of 6 levels, namely 0, 5, 10, 15, 20 and 25%. Each treatment was repeated 3 times, so that 18 experimental units were obtained. The variables observed in turmeric cream and tamarind leaves were homogeneity, viscosity, pH, dispersibility, adhesion, and separation ratio, antioxidant capacity, LAB color test. Data were observed and analyzed using a completely randomized design. The results showed that the extract of dragon fruit peel did not affect homogeneous separation ratio, viscosity, spread power, pH and antioxidant capacity, while color testing affected the brightness level of the cream and the yellowish value b. All treatments adding water extract of dragon fruit peel produce turmeric cream and tamarind leaves that are homogeneous, there is no separation, viscosity 6766-6850cP, spread ability 5.9-6.27 cm, adhesion 54.67-72.33s, pH 5.37-5.57, nalia color test values L 38.72 – 46.08, values A 27.41-34.98 values B 31.56-44.65 and antioxidant capacity 91,67-112,17. Keywords: Dragon fruit, turmeric and tamarind leaves, cream characteristics.

Tooth extraction causes prolonged bleeding complications and the body will respond with hemostasis. Currently developing natural medicines to help the process of hemostasis. Red dragon fruit peel, which is generally a waste containing tannins, flavonoids, and saponins to stop bleeding. Purpose was to find out the effect of red dragon fruit peel extract on bleeding time in the tail of Balb-C strain mice. 16 mice samples were adapted for one week. Mice were divided into 2 groups subsquently fasted for 7 hours. The first group as a control (0.5% Na-CMC). The second group was given red dragon fruit peel extract which was divided into three sub-groups at a dose of 0.5 mg / g BW, mg / g BW, and 1.5 mg / g BW. All samples were waited for 45 minutes and cut along 2 cm from the tip of the tail. Blood is spilled on Whatman paper which has 30 seconds in each box. The number of blood spots on the box was calculated and multiplied by 30 seconds. The result showed that bleeding time in the group given red dragon fruit peel extract was significantly lower (p <0.05) than in the control group. The conclusion was red dragon fruit peel extract (Hylocereus Polyrhizus) has an effect on shortening the bleeding time in cutting the tail of bulb-c strain mice and the dose of red dragon fruit peel extract (Hylocereus Polyrhizus) which has the most significant effect is 1 mg / BB mice.

Lead is the free radicals and heavy metals of major pollutants in the environment. Lead is toxic and cumulative. Red dragon fruit (Hylocereus polyrhizus) peel extract is a natural antioxidant. Red dragon fruit peel extract can be used to stabilize free radicals by supplementing electron deficiencies and inhibiting chain reactions. This study aimed to analyze therapy effect of red dragon fruit peel extract to increase the number of Sertoli cells on BALB/c mice (Mus musculus) exposed to lead acetate. Fourty mice were divided into 5 groups (each group consisted of 8 mice). K- group was the control group without lead acetate and dragon fruit peel extract administration, K + group was given 100 mg/KgBW lead acetate orally on the 1st day until day 14th.. P1, P2, and P3 group were continued with red dragon extract orally on the 15th day until 39th day. P1 with dose 250 mg/KgBW, P2 with dose 500 mg/KgBW, and P3 with dose 1000 mg/KgBW. The result showed significant difference (P<0.05) in the number of Sertoli cells between K+ and P1, P2, P3 group. In conclusion, dose 500 mg/kgBW of red dragon fruit peel extract can be used as the most effective therapy to increase the number of Sertoli cells on mice exposed to acetate lead.

The purpose of this study is to determine the effect of the red dragon fruit peels (Hylocereus polyrhizus) extract on the growth of Salmonella pullorum. This research was conducted at the Laboratory of Microbiology, Veterinary Faculty, University of Syiah Kuala, Banda Aceh. Red dragon fruit peels that used in this study is obtained from  ripe fruit and Salmonella pullorum cultures is  obtained from  Microbiology Laboratory of Veterinary Faculty Unsyiah. Salmonella pullorum culture added evenly on the surface of Mueller Hinton Agar, the number of the bacteria have been standarized using Mc Farland'1 method. Discs soaked in the red dragon fruit peels extracts at different concentrations (20 mg/ml, 40 mg/mL, and 60 mg/ml). Ampicillin is used as positive controls and DMSO (dimethyl sulfoxide) was placed on the surface of Mueller Hinton Agar. The parameters in this study is the inhibition zone diameter. Data were analyzed descriptively. The results showed that the red dragon fruit peel extract is able to inhibit the growth of Salmonella  pullorum and the average of  inhibition diameter zone at a concentration 60 mg / ml is 9.6 mm, 40 mg / ml is 9.4 mm and 20 mg / ml is 9.3 mm
