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: Sintesis kompleks salen Cu/Ni sebagai katalis oksidasi gliserol
Abstrak: Biodiesel sebagai salah satu alternatif pengganti minyak bumi telah menghasilkan produk samping berupa gliserol kasar. Salah satu cara pemanfaatan adalah dengan mengoksidasinya menjadi dihidroksiaseton menggunakan kompleks senyawa salen yang telah dihidrogenasi dengan logam atom pusat Cu dan Ni. Katalis yang dihasilkan dicirikan menggunakan spektrofotometer inframerah transformasi Fourier dan spektrofotometer serapan atom. Kinerja kedua katalis dalam mengoksidasi gliserol telah dibandingkan dengan baik dalam penelitian ini. Oksidasi gliserol dilakukan dengan tambahan katalis sebanyak 5 mol% gliserol dalam campuran gliserol-asetonitril. Reaksi dilakukan dengan melewatkan gas oksigen selama 4 jam pada suhu ruang dalam campuran tersebut. Hasil oksidasi dianalisis menggunakan kromatografi cair kinerja tinggi. Puncak kromatogram dari hasil oksidasi yang muncul setelah menit ke-9 menunjukkan terjadinya perubahan gliserol. Produk oksidasi gliserol diduga memiliki gugus fungsi keton karena nilai Rf-nya lebih besar daripada gliserol, yang menandakan senyawa tersebut lebih nonpolar daripada gliserol. Kromatogram yang diperoleh menunjukkan bahwa aktivitas katalis Cu(salen) mengoksidasi gliserol lebih baik ditinjau dari rendemen produk yang dihasilkan dibandingkan dengan Ni(salen). Oksidasi baik dengan Cu(salen) maupun Ni(salen) menghasilkan satu produk oksidasi.
