Abstrak: A description was given on the muscle anatomy of the hip and thigh of the Sumatran rhino. The study was conducted to observe the muscle anatomy, including their origins and insertions in order to describe the muscle functions and to compare the muscle structure with other animals. This study used cadaver of one adult male rhino preserved in 10% formaline. The muscles in the hip and thigh region 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 results were documented by photograph and the muscles were named based on Nomina Anatomica Veterinaria 2005. The muscles found in the hip and thigh region were gluteus superficialis, gluteus medius, gluteus profundus, tensor fasciae latae, biceps femoris, semitendinosus, semimembranosus, quadriceps femoris (vastus lateralis, rectus femoris, vastus intermedius, and vastus medialis), gemelli, quadratus femoris, sartorius, gracilis, pectineus, and adductor. Some muscles such as the gluteus superficialis, biceps femoris, semimembranosus, vastus medialis, rectus femoris, and sartorius were different. The muscle anatomy of the hip and thigh of the Sumatran rhino were quite similar to that of a pig, babirusa, and horse.

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: Penentuan energi aktivasi ion untuk melewati membran teflon pada berbagai larutan elektrolit
Abstrak: Kaseno (1999) menyatakan bahwa dalam teknologi pemisahan, membran adalah bahan yang dapat memisahkan dua komponen dengan cara yang spesifik yaitu menahan atau melewatkan salah satu komponen lebih cepat dari komponen lainnya. Kemampuan pemisahan yang dimiliki oleh membran untuk melewatkan suatu senyawa kimia atau molekul diakibatkan oleh adanya perbedaan sifat fisika atau kimia antara membran dengan senyawa kimia.
