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.

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.

Abstrak: One of the applications of membrane is pervaporation. Pervaporation is an efficient liquid separation using membrane. One of the compounds that can be purified is ethanol. Polystyrene membrane for ethanol pervaporation has several advantages, including easy for handling and reduced energy demand. Polystyrene membrane was prepared by adding nonionic surfactant (Pluronic®) as pore former. Pluronic® was added at various levels, i.e. 0; 0,5; 1; 1,5; and 2 g with time stirring of 10 and 20 hours for each composition. Characterization membranes was performed by Fourier Transform Infrared and surface morphology of membrane was determined by Scanning Electron Microscope. Pervaporation wathat produced the highest separation factor (αsep) of 38,9082 was obtained upon 20 hours stirring with addition of Pluronic® 1,5 g. The concentration of ethanol increased from 60% to 87%.
