Abstrak: Spotted dove and Javan turtle dove are the bird species that are easily raised in captivity. Nevertheless, good management is required to successfully breed and raise the birds in captivity; otherwise, the condition may endanger the sustainability of the two bird species. Information on ectoparasites on the bodies of this bird as well as their captivity breeding has not been available, although admittedly taking ectoparasites from these bird families has much been done so that a research is obviously needed. This study aimed to find out various kinds of Spotted dove and Javan turtle dove ectoparasites and to learn various kinds of parasitic insects around the Spotted dove and Javan turtle dove cages. The study was conducted from April to June 2010. The methods of data collection included the general condition of the location, collection of ectoparasites specimens, processing and specimens identification. The data analysis was done descriptively and tabulated with the degree of infestation. The kinds of ectoparasites from the class of insects found in the body of Spotted dove were Goniocotes sp. and Columbicola columbae of phthiraptera order and Pseudolynchia canariensis of diptera order, and arachnida class, that is, tungau from the pterolichidae family. In terms of ectoparasites, Spotted dove and Javan turtle dove were similar, except that Javan turtle dove had no Pseudolynchia canariensis. Goniocotes sp. and Columbicola columbae were mallopaga order (biting lice) and were obligate. The kinds of parasitic insects in the vicinity of Spotted dove and Javan turtle dove cages were from the Ordo Diptera. The diptera classified as parasites included Anopheles, Culex, Psychodidae, Culicoides and Simulium, most of them vectors of disease. The presence of ectoparasites was closely related to how a breeding place is managed.

Abstrak: Wildlife Rescue Center and Raptor Sanctuary are an ex-situ habitat for wildlife rehabilitation of confiscated and voluntary handover of illegal trading and poaching. This is the efforts to conserv wildlife from extinction. At present there is a few of javan hawk eagle and changeable hawk eagle on ex-situ habitat. Its existence can not avoid from the attack of various diseases, such as parasitic worm infections. The research aimswas to study the types and degree infection of gastrointestinal parasitic worms on javan hawk eagle and changeable eagle. This research was also a preliminary study in studying the behavioral factors and eagle health management at rehabilitation which may affect the transmission of parasitic worms. This research was conducted at Raptor Sanctuary, Cikananga Wildlife Rescue Center, and Gadog Wildlife Rescue Center on December 2009 until July 2010 by observed 16 eagles, which consisted of 4 javan hawk eagle and 12 changeable hawk eagle. Stage of research included field observation consisting of behavioral observation and fecal sampling. Behavioral observation was performed by Ad Libitum Sampling method and recorded by Time Sampling method. The stool sample done at each individual based on the time-making and observation of physical condition of fecal. The next stage was to analyze fecal samples on laboratory by Koprologi method which included qualitative and quantitative examination. Qualitative examination was done by flotation method and sedimentation followed by filtration storey. Quantitative examination was done by McMaster method. The type of parasitic worms found in this study are trematoda group consisting of Strigea sp dan Neodiplostomum sp, and the nematode group consisting of Heterakis sp, Ascaridia sp, and Capillaria sp. The type of parasitic worms found in javan hawk eagle are Ascaridia sp, Strigea sp, and Capillaria sp, whereas in changeable hawk eagle are Strigea sp, Neodiplostomum sp, Heterakis sp, Ascaridia sp dan Capillaria sp. There are two types of eggs worm, i.e. Ascaridia sp with 147,5 TTGT value which found in changeable hawk eagle on Cikananga Wildlife Rescue Center and Capillaria sp with 1868 TTGT value in javan hawk eagle on Gadog Wildlife Rescue Center. Transmission of worm infestation in those eagles allegedly influenced by several behavioral factor and wildlife management in ex-situ habitat.

Judul: Pengaruh Nisbah Reaktan Lignin-NaHSO3 dan pH pada Produk Natrium Lignosulfonat
Abstrak: Lignin diisolasi dari lindi hitam dengan pereaksi H2SO4 20%. Sulfonasi terhadap lignin menghasilkan NaLS yang dapat dimanfaatkan sebagai zat pendispersi, pengikat, penukar ion, dan aditif pada beton. Pada penelitian ini dilakukan sulfonasi terhadap lignin dengan nisbah reaktan lignin-NaHSO3 1:0.4, 1:0.5, dan 1:0.6 dan pH awal 5, 6, atau 7. Parameter yang diamati ialah kemurnian, pH akhir, dan Rendemen NaLS. Kenaikan pH awal meningkatkan pH akhir dan rendemen NaLS, tetapi menurunkan kemurniannya. Kenaikan nisbah lignin-NaHSO3 meningkatkan rendemen dan menurunkan kemurnian, tetapi tidak berpengaruh pada pH akhir NaLS. Kondisi optimum yang dipilih pada pH awal 6 dan nisbah lignin-NaHSO3 1:0.6. Pencirian gugus fungsi menggunakan spektrofotometri inframerah menunjukkan telah terjadi reaksi sulfonasi terhadap lignin. Hal ini dapat dilihat dengan terbentuknya serapan baru pada bilangan gelombang 626 nm yang menunjukkan ikatan C–S.
