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%).

Abstrak: Cacing simbion yang hidup di dalam saluran pencernaan hewan perlu dipelajari untuk membangun database fauna simbion. Penelitian ini bertujuan untuk mengidentifikasi cacing endoparasit pada saluran pencernaan kadal kebun Eutropis multifasciata (Scincidae, Squamata), yang hidup di sekitar kampus IPB Dramaga dan Gunung Salak Endah Bogor. Untuk pengamatan mikroskopis, cacing didehidrasai dan diwarnai eosin. Kadal yang terinfestasi cacing lebih banyak ditemukan di daerah Gunung Salak (66.67%) dibanding di Kampus IPB (30%). Di dalam tubuh kadal, cacing endoparasit terbanyak ditemukan di usus belakang (46.8%), kemudian berturut-turut di bagian kloaka (31.6%), usus depan (16.5%), dan lambung (5%). Cacing yang ditemukan dapat dikelompokkan menjadi Davaineidae (46.8%), Tetrarhynchobothriidae (36.0%), Trichostrongyloidae (15.8%), dan Rhabditidae (1.4%).

Abstrak: Growth of films Ba0,5Sr0,5TiO3 (BST) 1 M has been done with variation of annealing in hold time 8 hours, 15 hours, 22 hours, and 29 hours at constant temperature 8500C, above Si (100) substrate p-type, by using the sol-gel process method which followed with spin coating process at 3000 rpm for 30 seconds. Optics spectroscopy shows that BST film solar cells with annealing hold time 8 hours, 15 hours, and 22 hours, works effectively in wavelength ≥ 700 nm absorption range. Yet for sample with annealing hold time about 29 hours effectively absorb in ≤ 700 nm wavelength range. It obtained BST film refractive index at range 2.0 to 7.0 to wavelength range ±370-870 nm. Band gap BST film value based on annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours respectively 2.60 eV; 3.12 eV: 3.24 eV, and 2.66 eV. Electrical conductivity value which obtained, indicate that the BST film is classified as semiconductor material with conductivity order 10-5-10-4 S / cm. The result of I-V photovoltaic characterization shows the BST film potentially to be a solar cells device with efficiency according to the annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours in a row are 2.68x10-5%, 3.51x10-5%, 4.53x10-5% and 3.22x10-5%
