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 purpose of the study was to observe the muscles anatomy of the pelvic and thigh region of javan pangolin (Manis javanica) including the origin and insertion, and functions of the muscles related to pangolin behavior. Two specimen of javan pangolin preserved in 10% formaline was used in the study. The results were then compared with several animals that have related in phylogenic, anatomy and behaviour, from literature that related to the study. The muscles of pelvic and thigh region of javan pangolin that act as flexion and extension were m. tensor fascia lata, m. quadriceps femoris, m. gluteus medius, and m. gluteus superficialis. The muscles were relatively developed to produce maximum flexion and extension activity. The muscles that support adduction activity of hind legs were m. adductor magnus, m. adductor brevis, m. adductor longus, and m. gracillis. The most interesting result of the study was finding of m. abductor that absence in other mammalian muscles reported so far. The origin of the muscle was caudolateral side of os femoris and the insertion was caudodistal os tibia. It presumed that the muscle dominantly works as abduction of hind legs of javan pangolin. The pelvic girdle muscles such as m. psoas minor, m. psoas major, m. quadratus lumborum, and m. iliacus were well developed, thus helping the body to roll up. Therefore, it can be concluded that the muscle structure of the pelvic and thigh region of the javan pangolin have typical characteristics as digger and climber animal, and also support the body to roll up.

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%.
