Judul: Karakteristik Anatomi Skelet Tubuh Badak Jawa (Rhinoceros Sondaicus).
Abstrak: Badak jawa (Rhinoceros sondaicus) merupakan spesies mamalia besar di dunia yang paling terancam punah dan hanya dapat ditemukan di Taman Nasional Ujung Kulon (TNUK), Provinsi Banten, Indonesia. Tujuan dari penelitian ini adalah mempelajari karakteristik spesifik anatomi skelet tubuh badak jawa. Struktur skelet ini dikaitkan dengan fungsinya untuk menunjang ukuran tubuh yang besar dan perilakunya. Penelitian ini menggunakan satu set preparat skelet tubuh badak jawa. Parameter penelitian yang dilakukan adalah mengamati bentuk bagian skelet yang khas, mengukur panjang dan lebar tulang, serta dibandingkan dengan skelet tubuh badak sumatra dan hewan piara lain. Kemudian, sistem penamaan pada setiap bagian tulang dilakukan berdasarkan Nomina Anatomica Veterinaria (ICVGAN 2012). Karakteristik anatomi skelet tubuh badak jawa relatif mirip pada badak sumatera, tetapi memiliki ukuran yang lebih besar. Terdapat beberapa perbedaan yang ditemukan yaitu, ala atlantis lebih panjang, processus spinosus os axis berbentuk segiempat, processus transversus et spinosus tulang leher lebih subur, processus spinosus os vertebrae thoracicae relatif lebih mengarah ke kaudodorsal terutama pada sembilan ossa vertebrae thoracicae di kranial, daerah flank lebih sempit, dan ossa sacrales yang tersusun lebih kompak dan rigid. Secara umum skelet tubuh badak jawa memiliki hubungan yang sangat erat, kokoh, dan kompak, disertai penjuluran-penjuluran dan aspek kasar sebagai tempat melekatnya otot-otot dan ligamenta dengan kuat. Hal ini berperan dalam mempertahankan rigiditas dan menjaga sikap tubuh badak jawa terkait dengan habitat dan perilakunya.

Judul: Karakteristik anatomi skelet kaki belakang Badak Jawa (Rhinoceros sondaicus)
Abstrak: Javan rhinoceros (Rhinoceros sondaicus) is one of the rarest mammals which can be found only in Ujung Kulon National Park (UKNP), Banten Province, Indonesia. Behavioural study on this animal could be learned by studying their anatomy structure. The aim of this study was to learn about the characteristics of the javan rhino’s hind limb skeletal anatomy and was compared with the sumatran rhino’s hind limb skeleton. This study used a set of javan rhino’s hind limb skeleton which was brought from UKNP. The observation was done by measuring the skeleton, inspecting the structures and relating it to its behaviour, then capturing pictures of the skeleton. The elements of javan rhino’s skeleton were named based on Nomina Anatomica Veterinaria 2012. Generally, a javan rhino’s hind limb skeleton’s structure was relatively similar to a sumatran rhino. But, there are several differences in the structure that is assumed to be related to the difference in body size between those two species. The differences found were the wideness of ala ossis ilii. Furthermore, the trochanter major and trochanter tertius were more developed. An indentation (deep sulcus) was also found on dorsal side of os talus.

Judul: The Isolation of Silver (Ag) from Fixer Sludge with Electrolysis methode
Abstrak: with the variations concentration, electrode of carbon, and voltages. The aim of research are looking for the easiest and eficient electrolysis. Among of 272.79 ppm of silver (impurities) could be produced from electrolysis fixer which used 300 times maintain the film. For 400, 500, and 600 times electrolysis were produced recently 49.42, 137.04, and 55.22 ppm. Futhermore, it was increased to 220.00 ppm from 700 times. These were possible because of density the solutions. From the electrode of carbon, 68.2222 g Ag (impurities) could be processed from size 14 cm x 3 cm x 3 cm. The next results 41.2050 g and 43.7559 g from the sizes 16 cm x 3 cm x 3 cm and 18 cm x 3 cm x 3 cm. The reasoned of this part any faster reaction on the most litle electrode. By the way, from voltages variation, the processed showed that 47.4575 g of Ag (impurities) could be produced from 11 volt. It’s caused the bigest voltages are also the bigest kinetics power on the reactions. Sampel and product were analized by AAS. Consentration has potential to be indicator, because of the used 700 times was given trend high Ag (impurities) became increase optimally at 11 volt, and much sediment that is 47.4575 g. The best rendemen is 13.33%. The other finding is that the strength of the time and the voltages strongly enfluence the electrolysis shown by the bigger result on F(calculation) than that of the F(table).
