Judul: Analisis Pemanen Hujan dari Atap Bangunan SD Negeri Mulyasari di Desa Pulosari, Kecamatan Pangalengan, Kabupaten Bandung
Abstrak: Humans from the beginning has realized the importance of water for them and for the environment, because water is an essential natural resource that is needed by humans and other living things. Problems that are often encountered in Indonesia now a days is the presence of areas experiencing drought during the dry season, therefore clean water is scarce. The Average annual rainfall which is quite high in the area of pangalengan is uselles if it could not be used optimally. One of the way to do the rain harvesting is by collecting rainwater through the roof and stores it in a water tank. The roofing rain harvesting was carried out at SDN Mulyasari Pulosari village, Pangalengan district, Bandung regency. Based on the precipitation data in the Pangalengan region, it can be seen that Pulosari village has rain almost throughout the year with the different variations of rain annually. The precipitation data used in this study is downscaling data from Global Climate Model (GCM) for Citarum River Basin for the period 1981 to 2010. Based on the number of the people to be served, water needs in SDN Mulyasri is 10.770 liter/week (6 days). The calculation of rainfall tank volume was done by trial and error from the result of water balance calculation. Results calculation of the optimum capacity were 10.850 liters. A construction budget was needed to make water the tank. From the analysis of the budget expenses, it costs Rp 57.000.000 to make a tub with 10850 litres capacity.

Judul: Analysis of Rainwater Harvesting From Roof Building (Case Study: IPB Dramaga Campus Buildings Bogor).
Abstrak: The rise of the movement to save the environment for our next generation with the concept of green building becomes an important issue now. IPB which became part of Bogor city should take part to make it as a region as comfortable city of Bogor as a vision It had. One way of applying the concept of green building is to harvest the rain from the rooftops of the building. This study calculates the number of rainwater that can be harvested through the roof of the buildings on IPB Darmaga Bogor campus. Using monthly rainfall data average, broad roof of the building IPB Darmaga, then get the amount of rainwater that can be harvested. And using reference from the Technical Guidelines and Survey Procedures for Assessment of Drinking Water Supplies and Services and the Technical Guidelines Development Procedures Urban Water Supply Master Plan of the Directorate General of Public Works has the Department of Public Works to see in general the percentage of water which can be harvested to meet the needs of clean water for usage on campus. From analysis, water potential that can be harvested through the roof of the building on the campus of IPB Dramaga amounted to 319.734 m3 per year or equal to 52% of the average annual needs. Where, rainwater can be harvested in November, the highest (65%) and lowest in July (34%)

Judul: Pengaruh Penambahan Bio Adenosin Tri Phosphat terhadap Profil Kinetik dan Efektivitas Enrofloksasin dalam Mengatasi Coxiella burnetii
Abstrak: Coxiella burnetii belongs to rickettsia group living obligate intracellularly and as the agent of zoonosis Q fever. Enrofloxacine is an antibiotic in quinolon group used to treat infection of C. burnetii in chicken, goat, calve, pig, dog, cat, and horse. From ruminant practical experience, enrofloxacine if be combined with BioATP can enhance the enrofloxacine activity. Research for the effectivity of enrofloxacine and BioATP to treat C. burnetii has never been carried out. Enrofloxacine pharmacokinetic study was carried out by using simental beef as an experimental animals. The effectivity of BioATP supplementation on enrofloxacine activity to treat C. burnetii was tested by using Vero cell tissue culture. The results showed that combination of enrofloxacine and BioATP increased kinetic profile of enrofloxacine in term of onset, duration, pharmacology intensity, and bioavailaibility. Enrofloxacine had activity to treat C. burnetii with value of minimal inhibitory concentration (MIC) at 1-2 ppm and value of minimal bactericidal concentration at 4 ppm. Supplementation of BioATP improved the effectivity of enrofloxacine in treating C. burnetii.
