Abstrak: This study were aimed to analyze level of nutritional knowledge and consumption fiber and nutritional status of elementary school student. A Crosssectional design was used in this study. The subject of this research is 6 grade students about 30 students. The results showed an average intake of energy, protein, fiber and subject is 1630.7 kkal/day, 47.7 g/day, 5.9 g/day. The average water intake was 1576 ml/day. Nutritional knowledge of children and mothers are at the level of midle nutrition and good nutrition. Most of subject’s nutritional status are on the normal nutrition (56.7%) and the others are at the category of plump (30%) and obes (13.3%). The result showed that there was no significant correlation between level of a knowledge children and mother with status of child nutrition (r=-0.358, p=0.052 dan r=-0.134, p=0.481), fibers consumption of a child (r=-0.007, p=0.972 dan r=-0.163, p=0.390), and water consumption of a child (r=-0.221, p=0.241 dan r=-0.130, p=0.493). There was no significant correlation between consumption of fiber and nutritional status (r=0.207, p=0.273).

Judul: Correlation between Knowledge, Attitudes, Nutrition Practices, and Food Consumption with The Nutritional Status of Primary School-aged Children in Bogor City
Abstrak: Anak usia sekolah dasar membutuhkan asupan gizi yang baik sesuai dengan kebutuhannya. Permasalahan gizi pada anak dipengaruhi oleh kebiasaan makan dan aktivitas fisik anak. Tujuan penelitian ini adalah menganalisis hubungan pengetahuan, sikap, praktik gizi dan konsumsi pangan dengan status gizi anak usia sekolah dasar di Kota Bogor. Desain penelitian ini adalah cross-sectional yang dilaksanakan pada bulan September 2022-Januari 2023 di Kota Bogor. Subjek penelitian berusia 9-12 tahun dengan status gizi lebih sebesar 20% dan obesitas sebesar 12,5%. Pengambilan data dilakukan dengan pengisian kuesioner serta wawancara food recal 2x24 jam, recall aktivitas fisik 2x24 jam dan Food Frequency Questioner (FFQ). Tidak terdapat hubungan yang signifikan antara pengetahuan (p=0,313), sikap (p=0,172), praktik gizi (p=0,351), tingkat kecukupan energi (p=0,960), tingkat kecukupan protein (p=0,533), tingkat kecukupan lemak (p=0,785), tingkat kecukupan karbohidrat (p=0,555) dan aktivitas fisik (p=0,501) dengan status gizi., Primary school-age children need good nutritional intake according to their needs. Nutritional problems in children are influenced by eating habits and physical activity. The purpose of this study was to analyze the correlation between knowledge, attitudes, nutritional practices and food consumption with the nutritional status of primary school-age children in Bogor City. The design of this study was cross-sectional which was carried out in September 2022-January 2023 in Bogor City. The research subjects were aged 9-12 years with excess nutritional status of 20% and obesity of 12.5%. Data collection was carried out by filling out questionnaires as well as 2x24 hour food recall interviews, 2x24 hour physical activity recall and Food Frequency366 Questioner (FFQ). There was no significant relationship between knowledge (p=0.313), attitude (p=0.172), nutritional practices (p=0.351), energy adequacy level (p=0.960), protein adequacy level (p=0.533), fat adequacy level (p=0.785), level of carbohydrate adequacy (p=0.555) and physical activity (p=0.501) with nutritional status.

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.
