Judul: Konsumsi Pangan, Status Gizi, dan Status Yodium Anak Sekolah Dasar di Wilayah Pegunungan Kabupaten Cianjur
Abstrak: People in the mountainous region generally less consume food source of iodine and highly consume goitrogenic food. The pattern of the food consumption can reduce iodine status of people and further cause IDD (Iodine Defficiency Disorders). The general objective of this research was to analyze correlation between consumption habits of iodine source and goitrogenic and iodine status among elementary school children in mountainous areas in Cianjur district. Samples are elementary school children grade 5th or 4th aged 9 to 14 years; and the mothers of the children. This research was conducted in May to October 2012 used cross sectional design in 3 sub-districts of Cianjur District, West Java. Primary data consisted of food consumption, anthropometry, and iodine urine, whereas secondary data consisted of characteristics of Cianjur. The study showed that there was significant correlation between iodine total intake and the level of UIE (p<0.05, r=0.179), but there were no correlation between the frequency of goitrogenic food consumption and the level of UIE, and between the total intake of cyanide and the level of UIE (p>0.05).

Judul: Hubungan Pola Konsumsi Pangan Sumber Iodium Dan Zat Goitrogenik Dengan Status Iodium Dan Stunting Pada Siswa SD Di Kecamatan Kroya Kabupaten Cilacap
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan antara konsumsi pangan sumber iodium dan zat goitrogenik dengan status iodium dan stunting pada siswa SD di kecamatan Kroya, Kabupaten Cilacap, Jawa Tengah. Desain penelitian adalah cross sectional study. Sejumlah 69 siswa dari dua sekolah dasar diikutsertakan dalam penelitian ini. Kriteria inklusi untuk contoh yaitu berada di wilayah endemik GAKI dan merupakan siswa kelas 4 atau 5 SD. Hasil penelitian menunjukkan bahwa pangan sumber iodium yang sering dikonsumsi adalah ikan, susu, dan roti dengan total rata-rata konsumsi 50 gram setiap harinya. Pangan sumber goitrogenik yang sering dikonsumsi adalah kangkung, bayam, singkong, daun singkong, buncis, ubi jalar dan terong dengan total rata-rata konsumsi 59.9 gram setiap harinya. Rata-rata asupan iodium sebagian besar contoh dikategorikan kurang (<120μg/hari). Median nilai EIU contoh dikategorikan berlebih (>300μg/L). Tidak terdapat hubungan yang nyata (p>0.05) antara asupan iodium dengan kadar EIU, konsumsi pangan goitrogenik dan kadar EIU maupun kadar EIU dan status gizi (TB/U).

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.
