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 endoparasit pada kadal kebun (Eutropis multifasciata) di sekitar kampus IPB Dramaga dan Gunung Salak Endah Bogor
Abstrak: Worm symbionts, inhabitant in gastrointestinal tract of animal need studied for building a database of symbion fauna. The objective of this research was identifying the worms in the gastrointestinal tract of lizard Eutropis multifasciata, which lives around IPB Campus Dramaga and Salak Endah Mount. Worm dehydrated and stained by eosin for microscopic observation. Lizard more found in the Salak Endah Mount (66.67%) than in the IPB Campus Dramaga (30%). The endoparasite worm were mostly found in large intestine (46.8%), in cloaca (31.6%), small intestinal (16.5%), and stomach (5%) respectively. The worms belong to four families, that are Davaineidae (46.8%), Tetrarhynchobothriidae (36.0%), Trichostrongyloidae (15.8%), and Rhabditidae (1.4%).

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.
