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: Cacing parasitik pada ungko (Hylobates agilis F.Cuvier 1821) dan siamang (Symphalangus syndactylus Raffles 1821) di Taman Rekreasi Margasatwa Serulingmas Banjarnegara
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: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
