High temperatures lead to oxidative stress which can decrease the quality of spermatozoa. Watermelon’s rind have an ability for antioxidants effect that can reduce sperm’s damages that results by role explanation of free radicals. This study aimed to determine the effect of extract of watermelon’s rind on the motility and viability of sperm on male rat exposed to heat. This experiments use rat as animals experiment with five treatments and four repetitions. Five treatments are: P0: without exposured to 40˚C of temperature and without treatment by extract watermelon’s rind, P1: was exposured to 40˚C of temperature and without treatment by extract watermelon’s rind, P2: was exposured to 40˚C of temperature and treatments by extract watermelon’s rind dosage 20 mg/rat/day, P3: was exposured to 40˚C of temperature and treatments by extract watermelon’s rind dosage 40 mg/rat/day, and P4: was exposured to 40˚C of temperature and treatments by extract watermelon’s rind dosage 80 mg/rat/day. The treatment was done for 52 days. The results, P4 have the best effect that can be increase the motility and viability of rat’s sperm (Rattus norvegicus) exposed to heat.

White ginger which is also called Jahe Putih (Zingiber officinale) in Indonesia, is widely used in local Indonesian communities. It is a popular ingredient in beverages for stamina and also a bioactive ingredient for many traditional Indonesian food recipes. It is a popular ingredient in beverages for stamina and also a bioactive ingredient for many traditional food recipes. However, with the increase in demand for ginger related products, fake ginger formulated products are widespread in the market. This paper is disclosed the chemical profile of essential oil obtained from steam distillation of the local ginger. The results of this study can be used as a standard to detect original ginger. It was found that the chemical composition of the essential oil obtained from the white ginger contained 0.19% of a dried weight after 3 h of steam distillation. A total of 40 monoterpenoids (C10) and sesquiterpenoids (C15) secondary metabolite compounds were respectively detected in the oil.
