Judul: Kontribusi makanan jajanan, tingkat kecukupan energi dan zat gizi serta morbiditas anak usia sekolah dasar di kota Bogor
Abstrak: Tujuan umum dari penelitian ini adalah untuk mengetahui kontribusi makanan jajanan terhadap tingkat kecukupan energi dan zat gizi serta hubungannya dengan morbiditas pada anak usia sekolah dasar di Kota Bogor. Tujuan khusus penelitian ini antara lain: (1) Mengetahui karakteristik siswa dan orang tua siswa SD Swasta dan SD Negeri, (2) Mengetahui jenis dan frekuensi makanan jajanan yang dikonsumsi siswa, (3) Membandingkan kontribusi makanan jajanan terhadap total konsumsi sehari antara siswa yang bersekolah di SD Swasta dan SD Negeri di Kota Bogor, (4) Menilai dan membandingkan tingkat kecukupan energi dan zat gizi antara siswa yang bersekolah di SD Swasta dan SD Negeri di Kota Bogor, (5) Membandingkan morbiditas antara siswa yang bersekolah di SD Swasta dan SD Negeri di Kota Bogor, dan (6) Menganalisis hubungan konsumsi makanan jajanan dan tingkat kecukupan energi dan zat gizi dengan morbiditas anak usia sekolah. Pemilihan lokasi penelitian dilakukan dengan cara acak atau simple random sampling dengan kriteria berada di wilayah Kota Bogor serta bersedia menjadi tempat penelitian. Kerangka sampling diperoleh dari data Dinas Pendidikan Kota Bogor (tahun ajaran 2008/2009), yaitu 289 Sekolah Dasar (SD). Selanjutnya dipilih 2 SD Swasta dan 2 SD Negeri untuk dijadikan tempat penelitian. SD Swasta yang terpilih adalah Sekolah Dasar Islam Terpadu (SDIT) Aliya dan Sekolah Dasar Swasta (SDS) Pertiwi, sedangkan SD Negeri yang terpilih adalah SDN Baranangsiang dan SDN Kedung Badak I. Penelitian ini dilaksanakan dari bulan April sampai bulan Juni 2009. Contoh dalam penelitian ini adalah siswa kelas 5 SD yang berusia 10-13 tahun. Seluruh siswa tersebut dijadikan sebagai contoh penelitian setelah dikurangi siswa yang drop out karena tidak masuk saat penelitian berlangsung dan data dari siswa yang tidak lengkap. Jumlah contoh dari SD Swasta dan SD Negeri setelah dikurangi siswa yang drop out adalah masing-masing sebesar 120 dan 90 orang.

Judul: Keragaan status gizi, konsumsi pangan, tingkat kecukupan energi dan zat gizi anak di sekolah dasar dengan penyelenggaraan makanan
Abstrak: Children were source of potentials and next fighter of nation’s ideal. Thus, they need to get chance to normally growth and develop as wide as possible (BPS 2001). This research was aimed to obtain information about performance of nutritional status, food consumption, contribution of food in school, and also sufficiency level of energy and nutrients of children of Sekolah Alam Bogor and SDIT Insantama in 2010. Data for this research was taken from research entitled “Analysis of Food Management in Elementary School and Menu Quality of Student in School” (Reisi Nurdiani 2010). Sekolah Alam Bogor has modus of age distribution at 11 years (43.48%) and SDIT Insantama at 10 years (40.00%). Age distribution of both schools wasn’t significantly (p>0.05) different. Percentages of sample in Sekolah Alam Bogor were 69.6% for male and 30.4 for female, while for SDIT Insantama were 65.7% for male and 34.3% for female. There were no significant (p>0.05) difference of both schools based on sex. Samples of both schools have modus of normal nutritional status, were 43.5% at Sekolah Alam Bogor and 51.7% at SDIT Insantama. Nutritional status of both schools, for male, students in normal category was 43.8% for Sekolah Alam Bogor and 60.9% for SDIT Insantama; while for female, students in normal category was 42.9% for Sekolah Alam Bogor and 47.4% for SDIT Insantama. There were no significant (p>0.05) different of both schools based on nutritional status. Based on classification of food type, grains and animal based food were dominated the diversity and total of consumption, while fruits was the least variety. Average consumption of energy, proteins, calcium and phosphorous of SDIT Insantama were higher than Sekolah Alam Bogor; nevertheless Sekolah Alam Bogor has higher average consumption of vitamin A, vitamin C and iron than SDIT Insantama. Based on sufficiency level, sufficiency of calcium, vitamin A and vitamin C of both school was significantly (p<0.05) different, while sufficiency of energy, protein, phosphorous and iron of both school wasn’t significantly (p>0.05) different. Contribution of energy and protein of food from school food service in both school were about 30% of average energy and protein requirement of elementary school children.

Judul: Penyelesaian Masalah Rotasi Aliran Fluida Kental Von Karman Menggunakan Metode Homotopi
Abstrak: Von Karman equation is an equation that describes fluid viscous flow induced by infinite disk rotation. By assuming steady flow and laminar, viscous incompressible fluid flow is represented in Von Karman equation by an angular velocity and the vertical direction velocity as the independent variables. Von Karman equation is a nonlinear problem that is solved using the homotopy method. The use of homotopy method is done by defining an homotopy function that requires auxiliary parameters to control the convergent region of the solution. The solution is a recursive formula with given initial conditions. Using software based-functional shows that velocity components converge to a value.
