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: Onset, Durasi, dan Gejala Klinis Anestesi pada Kelinci New Zealand White (Oryctolagus cuniculus) dengan Kombinasi Ketamin-Xylazin Intramuskular
Abstrak: The aim of this research was to expound the onset, duration, and clinical signs observed on anaesthesia phase using ketamine-xylazine combination in New Zealand White rabbits. Fifteen New Zealand White rabbits (Oryctolagus cuniculus) were randomly subjected into three groups of five animals each. Those in group A were anaesthetized using a combination of 35 mg/kg ketamine and 5 mg/kg xylazine given i/m. Group B animals were anaesthetized using a combination of 40 mg/kg ketamine and 5 mg/kg xylazine while group C were anaesthetized using a combination of 45 mg/kg ketamine and 5 mg/kg xylazine, both given i/m. The result of this study indicated that the onset of anaesthesia marked by loss of pain response differ not significantly among the three groups (P < 0.05). Duration of anaesthesia and recovery significantly differ (P < 0.05) as the dose of ketamine increased. The onset of anaesthesia clinical signs within induction phase showed significant differences on sternal recumbency, lateral recumbency, and constricted pupil. Meanwhile the onset of anaesthesia clinical signs showed no significant differences (P<0.05) within recovery phase. It was concluded that onset of anaesthesia and clinical signs in induction phase were directly proportional as the ketamine’s dose increased. Meanwhile duration of anaesthesia and duration of recovery were inversely proportional with the dose increasing.
