Judul: Pertumbuhan Fisik dan Somatotype Anak Sekolah Suku Sasak pada Ketinggian Berbeda di Pulau Lombok
Abstrak: The human life cycle can be staged into neonatal, infancy, childhood, juvenile, puberty, adolescence, adulthood, and senescence. During this cycle, the body changes significantly in size, structure, proportions, and composition. The physical growth and somatotype of schoolchildren are one of the important phases in human life cycle. The puberty stage within this age range are indicated by the growth spurt of stature (BH) and weight (BW) and followed by change in somatotype. The focus of this research is to evaluate the age-related body size and shape variations at different altitude in Sasak children. A cross sectional growth study was conducted during July to December 2012. The samples are students of kindergarten to senior high schools aged 3 to 19 years. All of subjects are rural children who lives in low (16 to 28 m asl), medium (525 to 628 m asl), and high altitude (1130 to 1213 m asl). Ten anthropometric measurements are used to determined the growth of body size and shape. The result showed the children in low altitude were higher and heavier than medium and high altitudes. Until puberty, the children in medium have same stature and weight with those reside in high altitude but shorter and lighter thereafter. The difference of height and weight are statistically different in girls and indifferent in boys. In growth of body shape, the Sasak children have a common pattern of somatotype composition. It is an increased in endomorphy, a decreased in mesomorphy, and an increased in ectomorphy during growth. The girl in medium altitude show delayed and slowly increasing of endomorphy and slowly decreasing of mesomorphy. Socioeconomic factors such as family income and parental education gave more influence to the differentiation than the altitude factor.

Judul: Perawakan Anak Umur 4-19 Tahun di Kota Bandung
Abstrak: Somatotype in Indonesia had not been studied in Bandung City. The study aims to determine the physique of children aged 4-19 years in Bandung City and to see the physique development of children in each age class. It is carried out in girls and boys age 4-19 years old in Bandung City by Heath-Carter method. Girls had more endomorph component, while boys had more ectomorph component. Somatotype component of children aged 4-6 years both girls and boys are endomorphic-mesomorph. The correlation of Body Mass Index (BMI) to endomorph was higher in girls than in boys. Somatotype of girls and boys changed with age. Endomorph component in girls and ectomorph component in boys increased, but mesomorph component in both sexes decreased until the age of 19 years.

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%.
