Judul: Status yodium, status gizi, dan kecerdasan pada anak sekolah dasar di wilayah pegunungan Kabupaten Cianjur
Abstrak: Penelitian ini bertujuan untuk menganalisis status iodium, status gizi dan skor kecerdasan kognitif (skor IQ); dan untuk menganalisis korelasi antara yodium status dan status gizi dengan kecerdasan kognitif dan prestasi akademik di kalangan siswa sekolah dasar. Sampel penelitian berjumlah 155 siswa sekolah dasar. Data penelitian dikumpulkan dengan cara pengukuran, wawancara menggunakan kuesioner, dan diperoleh dari instansi terkait. Hasil studi menunjukkan bahwa rerata status iodium siswa termasuk dalam kategori ringan kekurangan (median 60,0 µg/L). Berdasarkan indeks BMI/A, sebagian besar siswa (86,5%) berstatus gizi normal, sedangkan berdasarkan indeks H/A, pelajar dikategorikan status gizi normal lebih rendah yaitu 54,8%. Kebanyakan siswa memiliki kecerdasan kognitif sebagai “rata-rata” (58,1%) dan di bawahnya rata-rata (37,4%). Lebih dari separuh siswa (62,6%) mempunyai prestasi akademis prestasi yang dikategorikan “baik”. Berdasarkan uji korelasi spearman, Terdapat hubungan yang cukup signifikan antara status iodium dengan kognitif cerdas (p=0,064) dan juga prestasi akademik (p=0,051). Disana ada tidak ada korelasi antara kecerdasan kognitif dan status gizi diukur dengan indeks BMI/A (p=0,266) atau indeks H/A (p=0,376). Selain itu, di sana tidak ada korelasi yang signifikan antara prestasi akademik dan gizi status, baik dengan indeks BMI/A (p=0,472) maupun indeks H/A (p=0,174). Namun, Uji korelasi spearman menunjukkan adanya korelasi yang positif dan signifikan status iodium dan status gizi, baik berdasarkan BMI/A (p=0,003) maupun H/A (p=0,033), kecerdasan kognitif dan prestasi akademik (p=0,000).

Judul: Kaitan Perilaku Gizi Ibu dengan Status Iodium, Kecerdasan Kognitif dan Tinggi Badan Siswa Sekolah Dasar di Daerah Pantai Kabupaten Karawang
Abstrak: This study aimed to analyze interelation between nutritional behavior (knowledge, attitude and practices) of mothers with iodine status, cognitive intelligent (measured by IQ scores and academic achievment) and height of elementary school students. The study design was cross sectional with subjects of elementary school students grade 5 and 6 and mothers/caregivers of the students with each number as many as 142. The result showed that there were significant correlations (p<0.05) between mothers’/caregivers’ nutrition knowledge and practices with academic achievement of children; mothers’/caregivers’ nutrition practices with IQ scores of children. There were no significant correlations (p>0.05) between knowledge, attitudes and practices of mothers/caregivers with iodine status and height of children; nutrition knowledge and attitude of mothers/caregivers with IQ scores of children; nutrition attitude of mothers/caregivers with academic achievment of children; and between iodine status with IQ scores, academic achievment and height of children.

Judul: Truncated Stop Loss as a Optimal Solution of Reinsurance Agreement in One-Period Model
Abstrak: Reinsurance is one of risk management efforts of an insurance company, which is called the cedent. Similar with insurance, reinsurance constitutes the cedent to pay the premium. We consider one-period reinsurance model and derive a rule which minimizes the ruin probability of the cedent for a fixed reinsurance premium. Therefore, it is needed to construct an optimal reinsurance agreement for the cedent. The premium is calculated according to four different principles, i.e. economic, generalized zero-utility, Esscher, and mean-variance principles. Stop loss is a reinsurance contract which protect the insurance company for losses that exceed a certain amount. The result of this research shows that a truncated stop loss is an optimal agreement in the class of all reinsurance contracts with various premiums calculated using above mentioned principles.
