Judul: Konsumsi Ikan dan Kaitannya dengan Status Gizi, Tingkat Kecerdasan, dan Prestasi Belajar Siswa Sekolah Dasar di Kabupaten Karawang
Abstrak: This study aimed to determine the relationship between fish consumption and nutritional status, intelligence level, and academic achievement among elementary school students in Karawang district. A Cross-sectional design was used in this study. Samples were 148 students of V and VI grades. The result showed that fish consumed by most samples are shrimp (88.5%), shellfish (81.8%), crab (80.4%), sardines (70.9%), and snapper fish (60.1%). Samples’s average fish consumption and protein intake from fish were 45 g/day and 10.9 g/day, respectively. A total of 60.9% and 70.9% samples had normal nutritional status by BMI/A and H/A. Intelligence Level (IQ) and academic achievement of samples were generally categorized as good. Spearman correlation test showed that there was no significant correlation between fish consumption (frequency, total, protein intake) and nutritional status, IQ level, and academic achievement (p > 0.05), except protein intake with H/A nutritional status (p = 0.020). Nutritional status by BMI/A was not correlated significantly with IQ level and achievement (p > 0.05). Whereas H/A nutritional status had significant correlation with IQ level on 90% confidence level (p = 0.076) and academic achievement (p = 0.029).

Abstrak: The general objective of this study was to analyze fish consumption, nutritional status and learning achievement of 4th grade elementary school children in coastal and non coastal areas. The research was conducted by using Cross Sectional Study design and implemented in September to Desember 2011 in Tanjung Pasir and Ciriung III elementary schools. Samples were determined by purposive sampling, 30 students from coastal and non coastal areas were chosen. Amount of fish consumption in coastal areas (57.6 g) was higher than non coastal areas (32.6 g). Most student in coastal areas (43.3%) and in non coastal areas (76.7%) were caregorized as normal based on BMI for age. There was no significant association between fish consumption with nutritional status. There was a significant association between nutritional status with learning achievement (height for age r=0.320, p<0.05 and BMI for age r=0.255, p<0.05). There was a significant association between fish consumption with learning achievement (p<0.05).

Judul: Sintesis 1-Kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai Prekursor Asam (S)-(+)-(6-Metoksi-2-naftil)propanoat
Abstrak: Senyawa 1-kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai prekursor asam (S)-(+)-(6-metoksi-2-naftil)propanoat disintesis dari bahan awal 2-metoksinaftalena. Tahapan sintesis diawali dengan klorinasi menggunakan 2 jenis pereaksi klorinasi, yakni isosianurat terklorinasi dan NaOCl. Klorinasi dengan isosianurat terklorinasi berhasil menyintesis 1-kloro-2-metoksinaftalena sebagai produk monoklorinasi melalui pencirian dengan kromatograf gas-spektrometer massa (GC-MS). Nisbah konversi produk paling efisien diperoleh pada laju penambahan 2.5 mmol/jam. Sebaliknya, klorinasi dengan NaOCl menghasilkan produk triklorinasi. 1-Kloro-2-metoksinaftalena selanjutnya diasilasi dengan propanoil klorida, tetapi analisis dengan GC menunjukkan bahwa produk asilasi tidak terbentuk. Sistem bebas-air diperlukan untuk keberhasilan proses asilasi tersebut.
