Judul: Hubungan Konsumsi Pangan Sumber Protein dan Iodium dengan Status Iodium Siswa SD di Daerah Pantai Kabupaten Karawang
Abstrak: Iodine Deficiency Disorders (IDD) is one of the nutritional problems in Indonesia that needs to get deep attention because it is closely related to mental development and intelligence that can affect the quality of human resources. The study aimed to analyze the association between consumption of protein and iodine food sources with iodine status of elementary school students in the coastal area of Karawang District. The design of study was a cross sectional with 142 elementary school students as the subjects. Primary data consists of food consumption, anthropometry, and iodine urine. The results showed that the mean of iodine status of students was categorized as excess iodine status. Based on BMI/A and H/A index, most of the subjects had normal nutritional status. The average amount of iodine intake and iodine adequacy levels of the subjects were mostly categorized as adequate. There was a significant negative correlation (P <0.05) between protein adequacy level (r = -0.253) with iodine status. There was no significant correlation between intake of total iodine and nutritional status with iodine status (p> 0.05).

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: Pricing of Lookback Options with Floating Strike Price Using The Monte Carlo Method
Abstrak: Opsi lookback adalah opsi yang payoff-nya bergantung pada harga saham terbesar atau harga saham terkecil yang dicapai selama masa berlaku opsi. Opsi lookback dikatakan dengan floating strike price jika nilai dari strike price sebesar harga saham pada saat jatuh tempo. Nilai hampiran opsi lookback ditentukan dengan metode Monte Carlo, sedangkan nilai eksak didapat dari nilai simulasi terbesar yang mampu dihitung oleh komputer. Berdasarkan hasil penghitungan, nilai galat relatif yang dihasilkan semakin kecil dengan semakin bertambah banyaknya simulasi yang dilakukan, sehingga metode Monte Carlo untuk menghitung harga opsi lookback dengan floating strike price konvergen ke nilai eksaknya., Lookback option is an option whose payoff depends on the maximum or minimum of the asset price reached during the option period. The lookback option is said to be a floating strike price if the value of the strike price is equal to the stock price at maturity. The value of the lookback option is determined by the Monte Carlo method, while the exact value is obtained from the largest simulation value that the computer can compute. Based on the calculation results, the resulting relative error value get smaller with the increasing number of simulations performed. Therefore, the Monte Carlo method to calculate the price of the lookback option with the floating strike price converges to the exact value.
