Abstrak: Halmahera Northern districts is an area that has the natural resources of marine source of iodine is high enough.Stock Fishery North Halmahera by 89.865 tons/year. But in reality the results of national survey of mumps since 1980 until 2003, North Halmahera including areas classifield as severe endemic Iodine Deficiency Disordes (IDD). IDD be one causes of decreased quality of human resources (HR) sector in a region. Therefore, the purpose of this study include: 1). Identification the conditions and diet of fishermen families; 2). Analyze the status (level endemism) of IDD in a family of fishermen in the district North Halmahera.; and 3). To determinine the factors (diet) most likely to be the cause of IDD in the district North Halmahera. This research was conducted in 2009 in 10 coastal district in North Halmahera. Identification of goiter or IDD conducted by Palpation/Tactile on the neck and measurement of iodine levels in urine of respondents who were purposively select (purposive sampling) 384 fishing families. Furthermore, respondents were asked to complete a questionnaire or be interviewed about the identity and level of knowledge and diet. Based on interviews or questionnaires and the information that majority of the respondents consume foods containing iodine is high (>100 μg/day) and goitrogenic substance consumption level is high (>10 mg/day), while the results of urinary iodine is obtained 0,5% higher, 84,4% of normal and 15,1% lower. Results palpability thyroid gland is known that the total goiter rate (TGR) of 11,7% at district level who fall into categories of mild endemic TGR with referente to the criteria of WHO. This value is lower than the National Goitre Survey in 1980/1982 and the results of the survey year in which the cluster 1995/1996 North Halmahera island of the West with 54,7% TGR. At district level, District Central Tobelo a district that most people with high levels of endemicity of IDD (TGR = 30%) while the lowest Kao District (TGR = 3,3%). Results Logistic regression analysis found that consumption of foods containing goitrogenic substances causing or likely to affect the IDD in fisher family of North Halmahera. Consumption of iodized salt a chance to reduce or prevent IDD or goiter by 0,027. While the consumption of foods containing goitrogenic substances likely to cause or increase the IDD or goiter of 0,101.

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).

Abstrak: Algoritme ElGamal adalah salah satu algoritme kunci publik dengan aritmetik modular p yang mempunyai struktur grip siklik Z(p). Tingkat keanaman algoritme ini terletak pada pemecahan masalah logaritme diskret dari Z(p). Akan tetapi, tingkat keamanan tadi tahun ke tahun semakin menurun yang disebabkan kemampuan pemecahan algoritme diskret semakin meningkat. Untuk memenuhi tingkat keamanan yang memadai dibutuhkan p yang cukup besar yang menyebabkan proses enkripsi dan dekripsi menjadi lambat.
