Abstrak: Ethanol extract of the wungu leaf has an antioxidant according to an in vitro test. The purpose of this study was to determine the antioxidant activity of the ethanol extract and its partitions in an in vivo study by analyzing the lipid peroxide concentrations of liver in the hyperglycemic Sprague Dawley rats. Solvents used for the multilevel partition of the etanol extract were diethyl ether, ethyl acetate, and n-butanol. Further step was a phytochemical compounds qualitative test for the extracts. Lipid peroxide analysis was done by taking four livers from each group, there were seven treatment groups; normal group (K-1), glybenclamide control (K-2), hyperglycemia control (K-3), ethanol (K-4), diethyl ether (K-5), ethyl acetate (K-6), and n-butanol (K-7). The ethyl acetate extract contains bioactive compounds such as saponins, steroids, and tannins with a yield of 0,23%. The ethyl acetate extract can reduce the lipid peroxide of the liver by 57,19% and this is significant (p <0,05) with other groups.

Abstrak: High level of glucose in blood can cause Diabetes Mellitus (DM). This desease can be treated by either chemical or herbal medicine. One of herbal plant which is expected to heal the desease DM is Wungu leaves. Glucose measurement was conducted to 7 group, normal group (K-1), negative control (K-2), positive control (K-3), ethanol extract of wungu leaves 25 mg/kg bb (K-4), 50 mg/kg bb (K-5), 100 mg/kg bb (K-6), 200 mg/kg bb (K-7). The measurement was conducted in 2 phase namely treatment phase, to determine the effect of ethanol extract of Wungu leaves on DM and post-treatment phase which is to determine the effectiveness of extract of Wungu leaves in dcreasing glucose in blood. The sample animal that is used is Sprague-dawley ratswhich is weighting ≥ 200 gram, the experimental is carried out for 21 days. The result shows that the extract of Wungu leaves effect on decreasing glucose level is blood of diabetes rats. The decreasing of glucose strat from > 200 mg/dL in day 4 to < 200 mg/dL in day 14. Post-treatment phase shows that K-3, K-5, and K-6 decrease significiently. Decreasing on K-3 indicate that glibenklamid is working good in decreasing glucose level in DM rats blood, glucose K-5 on 15th minute is lower than K-6, so it can be conclude that K-5 is more effective in decreasing glucose level on DM rats.

Judul: The impact and contribution of the tourism sector to the Indonesian economy : an I-O and SAM approach
Abstrak: Tourism is an important and strategic sector for the Indonesian economy. The sector has been growing for the last two decades to enhance its contribution to the GDP, employment, regional, local economy, and to strengthen the balance of payment. In particular, a planned economy was introduced to provide substantial opportunities to utilize tourism as a mechanism for national development. As a service-based sector, tourism as also considered to be a vehicle of converting the manufacturing economy to a service economy which makes the delivery of the product rather than the creation of the product the most important thing.
