Judul: Estimation model of birthweight based on waist circumference
Abstrak: Nutritional status of pregnant women can be measured by anthropometry which is simple and non expensive. Waist circumference of pregnant women (WCP) may reflects uterus dan fetus growth. The objective of this study is to develop an estimation model of birthweight based on WCP during the third trimester. For this purpose 250 pregnant women were selected from six health centers and five midwife clinics of Tanah Sareal, Bogor. Body height and weight, waist and hip circumferences, mid-upper arm circumference, fundal height were measured on 28th, 32nd , and 36th week of gestation. Body weight prior to pregnancy, history of pregnancy and birth, symptoms and diseases, and food consumption was collected through an interview. The results show the two most appropriate estimation models of birthweight are based on WCP (R2=28.58%) and body weight (R2=28.27%) on 28 week of gestation, with the equations are : birthweight = 166.4(WCP)3 - 977.6(WCP)2 + 1914.7(WCP) - 1246.6 and birthweight = 14.7(body weight)3 - 79.4(body weight)2 + 143.1(body weight) - 82.5. This implies that the WCP and body weight can be used as a simple predictor of birthweight and of fetus growth.

Judul: Kajian indeks massa tubuh (imt) dan pertambahan berat badan ibu hamil serta hubungannya dengan tumbuh kembang bayi lahir di kota ambon
Abstrak: ANNA HENNY TALAHATU. Study on Body Mass Index (BMI), Pregnancy Weight Gain and its Association with Infant Growth and Development in Ambon. Supervised by HARDINSYAH and AHMAD SULAEMAN The objective of this study was to analyze pre-pregnancy body mass index (BMI) and pregnancy weight gain and its relationship with birth weight and Apgar score. For this purposes a crossectional study design was applied for 200 giving birth mother from three hospitals and three health centers (Puskesmas) based on certain criteria of 18-35 yr, complete medical records. Data collected include medical record, maternal nutrition knowledge, food habit and socio-economic. The results show that 31% of pre-pregnant women was categorized as underweight. Mean weight gain is 12,6 ± 2,4 kg and weight gain by trimester was 1,9 ± 0.6 kg , 4.2 ± 1.1 kg and 6.5 ± 1.6 kg for the first, second and third trimester respectively. Mean birth weight was 2700 ± 617.9 gr, and mean birth length is 47,5 ± 3,6 cm. About 47.5% of the newborn infants were low birth weight and 20% had low Apgar score. BMI, anemic status, pregnancy distance, morbidity, socioeconomic, and maternal nutrition knowledge had a positive significant association with total weight gain (R2 = 0.489). Based on multiple linear regression analysis, the birth weight was associated with BMI, pregnancy weight gain, gestational age, anemic status, blood pressure,and upper arm circumference (R2 = 0.734); and the Apgar score was associated with pregnancy weight gain, anemic status, blood pressure, pregnancy complication, birth weigth especially low birth weight (R2 = 0.820).

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%.
