Abstrak: This study was conducted to observe the anatomical structure of pelvic and thigh muscles in Javan porcupine included their origins and insertions in order to describe the possible functions of each muscles. This study used two specimen of adult male porcupines preserved in 10% formalin. Observations carried out by observing the outer morphology of pelvic and thigh regions. Determination of structures, origins, and insertions of each muscles was done by dissecting the superficial and deep layers and the muscles were named according to the Nomina Anatomica Veterinaria 2005. The muscles which found in pelvic and thigh regions were the cutaneous, psoas minor, iliopsoas (psoas major and iliacus venter lateral et medial), quadratus lumborum, tensor fasciae latae, gluteus superficialis, gluteus medius, piriformis, gluteus profundus, biceps femoris, abductor cruris caudalis, semitendinosus, semimembranosus, quadriceps femoris (vastus lateralis, rectus femoris, vastus intermedius, and vastus medialis), gemelli, obturatorius externus, obturatorius internus, sartorius, gracilis, pectineus, adductor longus, and adductor magnus et brevis. The results showed that Javan porcupine has unique structure of pelvic and thigh muscles that is the prominent of cutaneous muscle was extended up to the pelvic and thigh regions, the quadratus lumborum with two bellies, and the course of biceps femoris and semitendinosus which reached up to the sacrum and coccygeal regions. The structure of these pelvic and thigh muscles are sugested to be related with the adaptation and behavior of Javan porcupine during erecting the quills, rattling the tail quills, rushing enemies, and digging burrows.

Abstrak: The study was aimed to observe the characteristic of javan porcupine shoulder and arm muscles and to compare with other animals which have similiarity on anatomy, phylogenetic, and behaviour. The study used two cadaver of javan porcupine that had been preserved in 10% formaline fixation. The muscles of shoulder and arm region were observed macroscopically include structure, origins and insertions after the skin was cut and opened. The results were photographed using a digital camera. Image were edited by using software Adobe Photoshop CS3® then named based on Nomina Anatomica Veterinaria 2012. The muscles found in shoulder and arm were the cutaneus, trapezius, rhomboideus, brachiocephalicus, latissimus dorsi, serratus ventralis, deltoideus, supraspinatus, infraspinatus, subscapularis, teres major, coracobrachialis, superficialis pectoral, deep pectoral, triceps brachii, tensor fascia antebrachii, m. brachialis, dan m. biceps brachii. The result showed that the muscles in javan porcupine were generally similar to dog and pangolin shoulder and arm muscles. However, there were differences in the muscles structure of the cutaneus, trapezius, serratus ventralis, and teres minor. The differences were presumed to be related with the adaptation to habitat, behavior, and their body.

Judul: Katalis Zink Ferit Tersubstitusi Cu untuk Oksidasi Benzil Alkohol
Abstrak: Katalis berperan dalam menurunkan energi aktivasi. Katalis ZnFe2O4 dan ZnFe2O4 tersubstitusi Cu disintesis menggunakan metode kopresipitasi untuk digunakan dalam oksidasi benzil alkohol. Katalis dicirikan dengan spektrofotometer inframerah (FTIR) dan difraktometer sinar-X. Spektrum FTIR menunjukkan puncak serapan dari ikatan Zn-O dan Fe-O masing-masing pada rentang 559‒575 cm-1 dan 419‒447 cm-1. Difraktogram menunjukkan terbentuknya fase tunggal Zn0.6Cu0.4Fe2O4 pada katalis ZnFe2O4 tersubstitusi Cu 20%. Benzil alkohol dioksidasi dengan sistem refluks. Konversi benzil alkohol meningkat dengan meningkatnya suhu. Kadar benzaldehida yang dihasilkan dengan katalis ZnFe2O4 tersubstitusi Cu 20% lebih tinggi dibandingkan dengan katalis ZnFe2O4 yang tidak tersubstitusi dan yang tersubstitusi Cu 60 dan 80%. Hal tersebut menunjukkan bahwa katalis ZnFe2O4 tersubstitusi Cu 20% memiliki kinerja yang lebih baik dalam oksidasi benzil alkohol menjadi benzaldehida dengan kadar benzaldehida 8.763%.
