Judul: Hubungan Tingkat Kecukupan Konsumsi dan Status Kesehatan terhadap Status Gizi Santri Putri di Dua Pondok Pesantren Modern di Kabupaten Bogor
Abstrak: The consumption adequacy level and health status affect the nutritional status. Meanwhile, little is known concerning to the consumption adequacy level, health and nutritional status of female adolescent boarders at Modern Islamic boarding schools which has a food service system. The aim of the study was to identify the consumption adequacy level and health status in relation to nutritional status of female adolescent boarders at two modern Islamic boarding schools in Bogor: knowing the process of a food service, energy and nutrients consumption; assessing energy and nutrients consumption adequacy level; determining nutritional and health status of female adolescent boarders; and revealing environmental condition of female adolescent boarders dormitory at Sahid and Ummul Quro Al-Islami modern Islamic boarding schools (PP Sahid and PP UQI). The study was an observational type used cross sectional design held for two periods, on April 2011 (PP Sahid) and from September to October 2011 (PP UQI). The subjects were 68 at PP Sahid and 87 at PP UQI of female adolescent boarders chosen by simple random sampling with purposive site selection. The results showed that both boarding schools did not meet the required food serving standard. The average of energy and nutrients consumption of subjects was still below the recommended adequacy value, except for vitamin B1 in the two groups of subjects (28,92 mg and 14,46 mg) and calcium in the subjects at PP Sahid (1018,35 mg). Most energy and nutrients consumption adequacy levels of the subjects were in the deficit category except for vitamin B1 consumption adequacy level in the subjects at PP Sahid (54,4%). Most (69,1% and 79,3%) nutritional status (BMI for age) of both groups of subjects was in the normal nutritional status category. Most (97,1% and 88,5%) health status of both groups of subjects was unhealthy (sick). The dormitory environmental conditions on both the boarding school had not fully met the health requirements. The results showed that energy and calcium consumption adequacy levels were significantly correlated with nutritional status (BMI for age) of the subjects. Meanwhile, the consumption adequacy levels of protein, vitamin A, B1 and C, phosphorus and iron were not significantly correlated with nutritional status (BMI for age) of the subjects. Besides, the health status was not significantly correlated with nutritional status (BMI for age) of the subjects.

Judul: Analysis of Food Service Management, Nutritional Adequacy Levels, and Nutritional Status at the Darul Fallah Agricultural Islamic Boarding School
Abstrak: Upaya pemenuhan kebutuhan gizi santri di pondok pesantren berkaitan dengan penyelenggaraan makanan yang ada di dalamnya. Penelitian ini bertujuan untuk menganalisis penyelenggaraan makanan, tingkat kecukupan gizi, dan status gizi santri di Pondok Pesantren Pertanian Darul Fallah Bogor. Desain penelitian ini adalah cross sectional. Subjek merupakan santri di Pondok Pesantren Pertanian Darul Fallah sebanyak 71 orang. Sebagian besar subjek memiliki status gizi baik (69,0%). Penyelenggaraan makanan menyediakan tiga kali waktu makan. Tidak terdapat siklus menu pada rentang waktu tertentu. Hasil penelitian menunjukkan bahwa masih terdapat hal yang memerlukan perbaikan di dalam pelaksanaan penyelenggaraan makanan, khususnya terkait fasilitas yang digunakan. Hasil penelitian menunjukkan bahwa, menu yang disediakan mampu memenuhi rata-rata kebutuhan zat gizi santri berupa energi (82,1%), lemak (80,4%), karbohidrat (92,2%), serta zat besi (103,2%), tetapi belum dapat memenuhi kebutuhan harian protein (57,4%) dan vitamin C (40,8%). Sebagian besar subjek mengalami defisit berat pada energi (53,5%), protein (93,0%), dan karbohidrat (77,5%), defisit pada vitamin C (88,7%) dan zat besi (67,6%), serta berlebih pada asupan lemak (50,7%). Hasil uji korelasi menunjukkan bahwa tidak terdapat hubungan yang signifikan antara tingkat kecukupan gizi dan status gizi subjek (p>0,05)., Efforts to meet the nutritional needs of the Islamic boarding school are related to the food service management contained in it. The study aims to analyze food service management, levels of nutritional adequacy, and nutritional status at the Darul Fallah Islamic Boarding School. The design of this study is cross-sectional. The subjects were 71 students at the Darul Fallah Agricultural Islamic Boarding School. Most subjects had good nutritional status (69.0%). Food service is provided three meal time/day. There is no menu cycle at a specific timeframe. The results show that there are still things that need to be improved in the implementation of food service, especially the facilities used. The results showed that the menu provided was able to meet the average nutrient needs of the subjects such as energy (82.1%), fat (80.4%), carbohydrates (92.2%), iron (103.2%), but has not able to meet the daily needs of protein (57.4%) and vitamin C (40.8%). Most of the subjects had severe energy deficits (53.5%), protein (93.0%), carbohydrates (77.5%), vitamin C (88.7%) and iron (67.6%), and excessive fat intake (50.7%). The correlation test results showed that there was no significant relationship between nutritional adequacy level and status of the subjects (p>0.05).

Judul: The Solution of Nonlinear Volterra Integral Equation using Linearization Method.
Abstrak: Many natural phenomena can be explained by mathematical models. One of those models is in the form of Volterra integral equation, which is usually nonlinear. Analitically, a nonlinear form is difficult to solve. Therefore, this research is aimed to discuss solution of Volterra integral equation using linearization method. Linearization is done to nonlinear integrand with Taylor series expansion. According to this linearization, a numerical solution of Volterra integral equation is obtained using MATLAB 7.0.1 software. Validity of this method is tested by comparing the approximate with the exact solution. The result of this research shows that the numerical solution agree with the exact solution quite well.
