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: Perencanaan Sistem Distribusi Air Bersih di Desa Pulosari, Kecamatan Pengalengan, Kabupaten Bandung - Jawa Barat
Abstrak: Water is a basic requirement in daily life. Without water, humans are not able to carry out their daily activities. In an effort to distribute clean water to the community, the pipe system could be utilized. In designing the pipe system, the things that need to be taken into account are the amount of capacity and speed of the flow of a fluid through a system of pipelines and other things required in terms of planning. The population of Pulosari on RW 05, 06, 11 and 14 in 2012 is 2950 persons. The purpose of this research is designing a clean water distribution system by utilizing the raw water source of the reservoir in Pulosari village, Pengalengan sub district, Bandung district - west java. The main parameters that need to be evaluated is the pipe, discharge, pressure, and headloss. The main parameters that need to be evaluated is the geometric pipe, discharge, pressure, and headloss. This research was conducted with the primary and secondary data collection which is then proceeded with data analysis using the Epanet 2.0 software. From measurement performed, during rainy season flowing water to a reservoir only reachedto 1,37 LPS, For that required planning distribution system better namely by increasing the capacity of a building intake so as to discharge distributed to a reservoir will increase the size of 4,5 LPS, Discharge is able to meet the needs of water until 2022 year. HGL acquired value is above the soil surface so as to produce a positive residual head, this causes the water can flow from the reservoir into the water tank. Besides the new design of the pipe is needed on the distribution networks of water from the reservoir into the sump by replacing the pipe diameter of 1.5 inches to 2 inches to enlarge the flow which occurred in the distribution network.

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.
