Judul: Keanekaragaman Jenis dan Nilai Ekonomi Satwa Liar yang Digunakan Sebagai Obat di Jawa Tengah
Abstrak: Indonesia has high biodiversity and endemism, however extinction rate is also high. Excessive harvesting and habitat destruction by human activity were the dominant factor leading to species extinction and biodiversity loss. Most of the people depend on biodiversity as foods, medicine and housing, but sometime they heedless sustainable utilization. This research was aimed to identify wild animal diversity utilized as traditional medicine and its economics value in Central Java. Research was carried out from May to August 2007 in Central Java Province. Information was obtained through semi structured questionnaires applied to 105 respondents from 19 sub-provinces. I recorded 54 animal species utilized in traditional medicine, 42 of which are wild animal species (vertebrates), 10 avertebrates and 2 livestock animals; whose products were recommended for the treatment of 50 types of illnesses. The most frequently quoted treatments were for respiratory system (20 species), skin disease (18 species) and increasing stamina and appetite (14 species). Reptiles (21 species), followed by mammals (11 species) and fishes (4 species) represented the bulk of medicinal species. Medicinal wild animal is not only used for local consumption, but also exported. The economic value of wild animal to human health in Central Java is estimated to reach Rp.1,421,714,004 per year. Excessive harvesting of medicinal wild animal might increase species loss which resulted in extinction. However, if harvest and trade are based on sustainable utilization, it will not only increasing economic benefit but also generate effort for conservation.

Judul: Pemanfaatan Reptil dan Amfibi di Kota Jakarta dan Bandung
Abstrak: Penelitian mengenai pemanfaatan satwa liar khususnya herpetofauna (amfibi dan reptil) sebagai obat masih sedikit dilakukan. Pulau Jawa yang mencakup 7% dari luasan Indonesia merupakan wilayah dengan total penduduk 150.4 juta jiwa atau 56.34% dari total pendududuk Indonesia. Oleh karena itu penelitian mengenai pemanfaatan herpetofauna sebagai obat di kota besar di Jawa dan aplikasi konservasi perlu dilakukan secara mendalam. tujuan penelitian ini adalah untuk mengetahui karakteristik pedagang dan konsumen obat yang berasal dari herpetofauna serta menelaah persepsi pedagang dan konsumen obat yang berasal dari herpetofauna dan pemanfaatannya sebagai obat.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
