Abstrak: Agile gibbon (Hylobates agilis F. Cuvier 1821) and siamang (Symphalangus syndactylus Raffles 1821) are Indonesian endemic species. Aim of the study to determine the existence and the type of parasitic worms that infected agile gibbon and siamang at Serulingmas Zoological Garden, Banjarnegara. From Juli 2009 to February 2010, feces from three heads of agile gibbon and three heads of siamang was collected each week. All of samples were examined with quantitative and qualitative examination. Identification is achieved by the use of faecal cultures. The result showed that parasitic worms of agile gibbon were Trichostrongylus spp. and Strongyloides spp. and parasitic worms of siamang were Trichuris spp., Trichostrongylus spp., Strongyloides spp., and Cooperia spp. The result of quantitative examination showed that degree of infection by parasitic worms in agile gibbon and siamang belonging to low infection.

Judul: Infestasi Cacing pada Orangutan Kalimantan (Pongo pygmaeus) dan Orangutan Sumatera (Pongo abelii) di Taman Margasatwa Ragunan
Abstrak: Bornean and Sumatran Orangutans are endemic faunas which are classified by CITES in Appendix 1, list that contains species of faunas which are threatened for commercial international trading. Orangutans are included as endangered animals as the result of the decrease of habitat and illegal hunting so it needs conservation effort. The purpose of this research are to study the species of gastrointestinal parasite (worms) in orangutans, such as Strongiloides, Ancylostoma and Trichostrongiloid that could be transfered within the population and transmitted from orangutans to human, also to study the degree of worms infestation in orangutans. Fresh fecal sample was collected in Ragunan Zoo, and put into buffer formaline 10%. Fecal sample was examined with native method,modified filtration-sedimentation method and calculating TTGT (egg in each gram feces) by using Mc.Master method. Fecal sampel was examined natively and found several worm egg type, those are ascarid, strongiloides, trichostrongiloid and trichuris. The sedimentation examination was done by using sugar-salt liquid and filtered levelly for detain trematoda eggs, however all sampels not showed positive result. Based on the result of fecal examination of orangutans in Ragunan Zoo showed that Bornean and Sumatran Orangutan were positively infected by Nematoda worms. Orangutan at Ragunan Zoo were infected by 4 worm eggs type those are strongiloides type, ascarid type, strongiloid type and trichurid type. Bornean orangutan and Sumatran orangutan were infected by ascarid worm egg type and strongiloides worm egg type with low-moderate risk infection. The strongiloid worm egg type infected the orangutan at Ragunan Zoo with low risk infection meanwhile the trichurid worm egg type founded only at one animal.

Judul: Membran polistirena dengan ragam suhu perendaman untuk pervaporasi alkohol
Abstrak: Polystyrene membrane with PLURONIC as porogen, can be utilized in alcohol pervaporation. The polystyrene membrane was made by reverse phase method which was started with making of polymeric mixed solution between polystyrene and PLURONIC in dichloromethane with 2 different compositions, i.e.-polystyrene :PLURONIC:dichloromethane 17:0:83 and 17:1:82. The solution was stirred up for 5 hours with ultrasonic and casted on the glass plate surface, and then it was immersed into water at 40, 50, and 60 oC. The highest pervaporation result was 90,2% alcohol purities at 50 oC immersion temperature. However, this result was not good enough because the alcohol purities was lower than the standard alcohol purities at 91,6%.
