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).

Judul: Status Iodium, Status Gizi dan Kecerdasan pada Anak Sekolah Dasar di Wilayah Pantai Kabupaten Karawang
Abstrak: The study was aimed to analyze iodine status, nutritional status and intelligence and also to analyze correlation between iodine status and nutritional status with cognitive intelligent and academic achievement among elementary school students. The samples were 142 students of elementary school. The results showed that the mean of iodine status of students was categorized as leftover. Based on BMI/A and H/A index, having normal nutritional status. Most of students were having cognitive intelligent as “average”. Highest percentage of categorized academic achievement is “sufficient”. Based on pearson correlation test, there was a no significant correlation between iodine status with cognitive intelligent and also with academic achievement. There was significant between cognitive intelligent and nutritional status measured by H/A index, but have no correlation by BMI/A index. Almost significant correlation showed between academic achievement and nutritional status with H/A index, but have no correlation by BMI/A index. No significant correlation also showed between iodine status and nutritional status, whether by BMI/A or by H/A.

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.
