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: 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: Karakteristik Piezoelektrik Film LaxSr₁-xTiO3 di atas Substrat TCO
Abstrak: Studi material perovskite SrTiO3 sudah banyak dilakukan dan menunjukkan sifat feroelektrik, piezoelektrik, kuantum paraelektrik dan superkonduktor yang baik. Dengan penambahan dopant La2O3 diduga menambah performa sifat piezo dan karakteristik lainnya. Karakteristik film LaxSr₁-xTiO3 (LST) dengan variasi x= 0, 0.02, 0.04, 0.06 terbentuk pada suhu annealing 550 oC di atas substrat TCO melalui metode (Chemical Solution Deposition) CSD dan spin coating dengan 700 rpm pada kondisi suhu ruang dan tekanan atmosfer standar. Hasil menunjukkan, semakin banyak pendadah La maka nilai ketebalan film, ukuran rerata kristalit, parameter kisi, transmitansi, nilai konduktivitas (maksimum 589.7 S/cm pada sampel x=0.04 di frekuensi 10 Hz), nilai konstanta tegangan (c) dan muatan (d) piezo semakin meningkat. Dinamika bentuk grafik nilai tegangan (V) dan konstanta regangan mekanik (s) nampak mirip. Nilai V mencapai 0.127 V untuk x=0.06 (beban 50 g). Nilai maksimum c, d, s masing-masing mencapai 20.07 Vm/N, 1.14x10-8 C/N, 13642.71. Nilai band gap untuk x=0, 0.02, 0.04, 0.06 masing-masing 3.21 eV, 3.1 eV, 2.6 eV, 2.4 eV. La2O3 menambah performa sifat piezo, sehingga LST berpotensi sebagai sensor tekanan.
