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: 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: The use of homotopy perturbation methode to solve fuzzy volterra  integral equations
Abstrak: Most phenomena in nature can be explained in mathematical models, such as fuzzy volterra integral equation. The fuzzy volterra integral equation is a nonlinear integral problem, which is usually dificult to solve by an analytical solution. In this paper, fuzzy volterra integral equation is solved using perturbaion homotopy method, which can be written as a power series in p and satisfies a certain homotopy fuction. This manuscript discuss two case studies, i.e. the case of linear and trigonometric kernel function. The result shows that greater approximation order being used, the wider convergence solution area wil be.
