Abstrak: Java Island is the most populous island in Indonesia, which is 833 people/km2 and the population reach about 58% of Indonesia total polulation. Population and economic growth also resulted in annual electricity consumption increased by 9%, which can lead to energy crisis. The objective of this research is to mapping out the locations that have potential for build the microhydro power plant based on predetermined criteria. The criteria are determined based on the literature stating that minimal slope of 45° and a head of 2 meter are located on river flow that have minimal discharge 0.25 m³/s. Head and minimal slope were analyzed using 30 of ASTER DEM data. The discharges are estimated by using the data from PDA and land use data with debit balance equation and weighting coefficients of runoff. The result from this research can identify 90 point of potential micro hydro with power 2.04 MW and all categories of hydroelectric power plant amounted to 20.26 MW.

Abstrak: Planning development Project of Micro Hydro Power (PMHP) is one of the important thing in the allocation of water resources in rural areas. Planning PMPH observed located in Kubang Baros Village, Serang District, Banten. In planning PMPH, besides planning design capacity of the production electricity, need to know the condition of existing allocation of water resources in the upstream areas. Allocation of water resources accounted by predict water demand for region subdistrict Cinangka, Padarincang and Ciomas in 2050. Calculation water needs aims to the amount of water available can sustain to be used in a long time. So, the allocation for water resources can be run in sustainable and stable. Based on the results of the study determined that the Cidanau Watershed produce reliability discharge equal to 3.51 m3/sekon, with a prediction of water requirement in 2050 is 2.1 m3/sekon. The conclusion for this planning design of electrical production capacity produces electrical power equal to 387.91 kW.

Judul: Buprenorphine and Fischer-344 Rats Post-operative Stress Levels: Impact on Serum Corticosterone Levels.
Abstrak: The use of laboratory animals in experiment often requires surgical operations. Post-operative condition often associated with pain and stress. Preemptive analgesia and post operative treatment with buprenorphine can reduce post operative pain and stress and prevent prolonged pain. Therefore, the aim of the present study was to test the hypothesis that pre operative treatment of buprenorphine reduces stress and suppresses the pre-operative serum corticosterone levels in Fischer 344 rats. A total of 14 adult male Fischer 344 (F344/Sca) rats permanently catheterized in artery carotis communis were used. During 94 hour post-operatively the blood sample was collected at specific time point using Accusampler®, an automated blood sampling. Corticosterone levels were quantified with ELISA method using sheep polyclonal antibody to corticosterone. Buprenorphine is effective as pre-emptive analgesia in F344 strain. However the dose is higher than what has been reported in Sprague Dawley strain. Buprenorphine 1.0 mg/kg significantly suppressed serum corticosterone levels immediately after rats regain consciousness. Rats in buprenorphine 1.0 mg/kg group were protected from post operative body weight loss and reduced water intake compare to control, nutella, and buprenorphine 0.4 mg/kg group. Quantification of fecal corticosteroid metabolites failed to detect stress in present study.
