Judul: Karakteristik anatomi skelet kaki depan badak jawa (Rhinoceros sondaicus)
Abstrak: The study was aimed to observe the anatomical characteristics of forelimbs skeleton of javan rhino. The study was conducted by observing one set of the forelimbs skeleton of javan rhino and then compared with sumatran rhino (Dicerorhinus sumatrensis) and other animal from literature, related to the function and behaviour. The results showed that the forelimbs skeleton of the javan rhino was relatively short and compact. The scapula had a large tuber spinae scapulae that triangular-shape and the facies serrata was not separated into two parts by the fossa subscapularis. The humerus had a large tuberositas deltoidea with undeveloped crista humeri. The radial and ulnar were had narrow spatium interosseum antebrachii, while olecranon of the ulnar was a single tuber. Facies palmaris of the carpal bone had an extension which leads to mediodistal. In general, forelimbs skeleton of javan rhino was resemble to forelimbs skeleton of sumatran rhino, cows, and pigs. This condition were presumed to be related to the adaptation of body size, habitat, and their behaviour.

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: Pervaporasi Alkohol Menggunakan Membran Polistirena-SDS
Abstrak: Polystyrene (PS) membrane with SDS as porogen can be utilized as a filter in alcohol pervaporation process. The membrane was prepared using inversed phase method with PS:SDS:dichloromethane solvent composition were 17:0:83; 17:0.5:82.5; 17:1:82; 17:1.5:81.5; and 17:2:81. Homogenization of mixtures were carried out for 10 and 20 hours and casted on glass plate surface then submerged it into water with temperature of 60 °C. Pervaporation capability was evaluated from flux value and separation factor. The average of water flux values in 20 hours sonication were higher than the values in 10 hours sonication. The highest separation factor was observed in PS membrane with 0.5% SDS concentration and homogenization in 20 hours is 5.23. Application of PS membrane in pervaporation as showed by purities of alcohol value using gas chromatography method revealed that the purities increase from 91.6 to 93.4%. Therefore, certain SDS addition can increase the performance of PS membrane in alcohol purification.
