Abstrak: The study was aimed to observe the characteristic of sumatran rhino body muscles and compared with domestic animals which has similarity on anatomy, phylogenetic, and behaviour. One cadaver of Sumatran rhino named Torgamba donated from Sumatran Rhino Sanctuary (SRS) Way Kambas that had been preserved in 10% formaline fixation was used in the study. The muscles were observed macroscopically after the skin was cut and opened. The origin and muscle insertions were determined after dissecting the fascia and muscle. The muscles were identified and named based on literature and Nomina Anatomica Veterinaria 2012, and documented with a camera. The muscles found in neck, thorax, and abdomen were the splenius, semispinalis capitis, obliquus capitis cranialis et caudalis, longissimus capitis et atlantis, longus colli, serratus dorsalis cranialis et caudalis, iliocostalis thoracis, longissimus dorsi, spinalis et semispinalis, levatores costarum, multifidi, intercostales externi et interni, scaleni, transversus thoracis, obliquus externus abdominis, obliquus internus abdominis, transversus abdominis, rectus abdominis, iliopsoas, and psoas minor. The result showed that the Sumatran rhinos body muscle are generally resemble to the body muscle of pig and horse. However, there were differences in muscle structure especially of the serratus dorsalis cranialis et caudalis, intercostales externi, rectus abdominis, and obliquus capitis cranialis. The differences were presumed to be related to the adaptation of body size, habitat, and their behavior.

Abstrak: The study was aimed to observe the muscle anatomy of the shoulder and upper arm region of the Sumatran rhino, including their origins and insertions in order to describe the functions of the muscles and compare with other animals. This study was used one samples of Sumatran rhino preserved in 10% formaline. The muscles were observed macroscopically after the skin was incised and opened. The origins and insertions of the muscles were determined by dissecting the fascia and the muscles. The name of muscles based on Nomina Anatomica Veterinaria (ICVGAN 2005) and results were documented by photograph. The muscles found in shoulder and upper arm region were the trapezius, brachiocephalicus, latissimus dorsi, serratus ventralis, supraspinatus, infraspinatus, teres minor, subscapularis, rhomboideus, superficial pectoral, deep pectoral, teres major, deltoideus, triceps brachii, tensor fascia antebrachii, coracobrachialis, biceps brachii, and brachialis. The results showed that generally the Sumatran rhino’s muscles were quite similar to that of a pig, horse, and babirusa. However, there were differences in muscle structure especially in the rhomboideus, serratus ventralis, superficial pectoral, deep pectoral, deltoideus, infraspinatus, and biceps brachii muscles. The differences were related to the adaptation of Sumatran rhino’s large body and their behavior.

Judul: Membran Komposit Polivinil Alkohol-Zeolit Berporogen Polietilena Glikol untuk Pervaporasi Etanol.
Abstrak: Pervaporasi adalah proses pemisahan etanol-air menggunakan sistem membran dan tekanan. Pervaporasi membutuhkan membran hidrofilik untuk memisahkan etanol dari air dengan optimum. Membran komposit polivinil alkohol (PVA)-zeolit berporogen polietilena glikol (PEG) dibentuk pada penelitian ini untuk menjadi membran pervaporasi. Komposit PVA-zeolit dibentuk untuk meningkatkan kestabilan dan kinerja membran, sedangkan penambahan PEG bertujuan membentuk pori membran. Zeolit alam asal Cikalong, Tasikmalaya yang digunakan diaktivasi menggunakan NaOH 3.5 M dengan nilai kapasitas tukar kation 291.69 mg ek/100 g. Membran disiapkan menggunakan metode inversi fase dengan ragam tambahan PEG 0; 2.5; dan 5 %. Kinerja membran pada pervaporasi dievaluasi berdasarkan peningkatan konsentrasi etanol dan faktor separasi. Peningkatan konsentrasi etanol dan faktor separasi tertinggi diperoleh pada membran komposit PVA-zeolit tanpa penambahan PEG, yaitu 22.5 % dan 5.31. Pencirian morfologi permukaan membran menunjukkan membran yang terbentuk adalah membran asimetrik.
