Judul: Cacing parasitik pada unta punuk satu (Camelus dromedarius) di Taman Rekreasi Margasatwa Serulingmas Banjarnegara Jawa Tengah
Abstrak: The objective of the study is to reveal the existance of parasitic worm of one humped camel (Camelus dromedarius) in Serulingmas Zoological Garden. The fresh fecal samples were taken from the male and female camel, every week for six weeks. The samples were observed qualitatively and quantitatively to reveal the existance of parasitic worm eggs. The result of the study showed that the infection occured only in the female camel, but none in the male camel one. The type of worm eggs was identified as nematode parasitic, of the genus Trichuris with characteristic of oval in shape, polar plug in each side, thick walled, sized around 71-77,6 μm and 30,8-37,9 μm in length and width respectively. The average number of EPG (eggs in each gram of feces) was 333. Some factors which might be able to affect the worm infections in case of one humped camel are were feed, environment, and the susceptibility of the camel itself. The study proves that the female camel is more susceptible to worm infections than those the male one.

Judul: Eksplorasi Cacing Endoparasit Saluran Pencernaan Satwa di Kebun Binatang Semarang
Abstrak: Zoo is the place where some animal species collected together in artificial environment. Parasites exploration in zoo needs to be done to monitoring of parasites spreading in animals zoo collection. This study aimed to explore the gastrointestinal endoparasitic worms of wild captive animals in Semarang Zoo. The flotation and precipitation methods were used to detecting presence or absence the gastrointestinal endoparasite of worm eggs in fecal samples. In Semarang Zoo there were 17 species (54.84%) out of 31 wild captive animals were found to be infected by parasites. Seventen genera of endoparasitic worms were determined after identification. The most common endoparasitic worms found in Semarang Zoo were Nematodes, followed by Cestodes and Trematodes. Endoparasitic worms found in mammals were Nematodes (Ascaris sp., Toxocara sp., Ancylostoma sp., Bunostomum sp., Oesophagostomum sp., Haemonchus sp., Cooperia sp., Trichostrongylus sp., Trichuris sp., and Capillaria sp.), and Cestodes (Spirometra sp., Taenia sp., Hymenolepys sp., Diphyllobothrium sp.). Meanwhile, in aves Nematodes (Amidostomum sp., Capillaria sp.) and Trematodes (Alaria sp.) were determined. Whereas only Nematodes (Rhabdias sp.) were determined in reptiles. Capillaria was the only parasite found in mammals and aves.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
