Pembelajaran di Pendidikan Anak Usia Dini dengan Perkembangan Kognitif pada Anak

Perkembangan kognitif merupakan aspek perkembangan yang muncul dan berkembang pesat ketika masa usia dini karena 50% potensi kognitif terbentuk pada empat tahun pertama kehidupan. Perkembangan kognitif berkaitan dengan kualitas hidup manusia. Tujuan penelitian ini untuk mengetahui faktor dominan yang berhubungan dengan perkembangan kognitif. Penelitian dilakukan pada bulan April 2013. Desain penelitian adalah potong lintang dengan teknik pengambilan sampel menggunakan proportional random sampling. Sampel penelitian adalah 128 anak usia dini 24-72 bulan yang mengikuti pendidikan anak usia dini (PAUD) atau pun tidak ikut PAUD di Desa Talagamulya Kabupaten Karawang. Perkembangan kognitif sebagai variabel dependen. Sementara variabel independen adalah karakteristik anak (usia, berat badan lahir, status gizi tingi badan per umur (TB/U), asupan energi, protein, vitamin A, zat besi, zink), karakteristik ibu (usia, pekerjaan, pendidikan, pengetahuan), serta pembelajaran di PAUD. Uji regresi logistik digunakan untuk analisis multivariat. Hasil penelitian menunjukkan anak usia dini dengan kognitif baik 61,7%. Uji kai kuadrat menunjukkan faktor yang berhubungan dengan perkembangan kognitif yaitu asupan vitamin A, asupan zink, pengetahuan ibu, dan pembelajaran di PAUD. Faktor dominan yang berhubungan dengan perkembangan kognitif dalam penelitian ini yaitu pembelajaran di PAUD.Cognitive development was a developmental aspect that was emerged and thrived when the preschool years because 50% of the potential cognitive formed in the first 4 years of life. Cognitive development related to increasing the quality of human resource. The objective of the study was to know dominant factor associated with cognitive development early childhood. The design study was quantitative using cross-sectional study. Sample study were 128 early childhood 24-72 and collected information on April 2013 inTalagamulya Village, Karawang district. Cognitive development as dependent variable, was gathered using questionnaire. Independent variables were children's characteristics (birth weight, nutrition status/height for age, intake of energy, protein, fe, zinc, vitamin A), mother's characteristics (age, education, job, knowledge), and participation in early childhood education. The logistic regression was used for analyze data. The results of this study showed early childhood with good cognitive 61.7%. Chi square analysis showed intake of vitamin A, zinc intake, maternal knowledge, and follow early childhood education significant associated with cognitive development. The dominant factor associated with cognitive development was the participation in early childhood education

Asupan Gizi dan Mengantuk pada Mahasiswa

Nutrient and energy intake, nutrition status, and daily activity could give impact for sleepiness problem. Sleepiness related to the decreasing of cognitive ability that caused by iron deficiency. A person who feels sleepy will have a lack of physical activities that lead to overweight and therefore has a higher risk to suffer degenerative diseases such as cardiovascular and diabetes mellitus. This study aimed to analyze dominant factor that can give influence to sleepiness problem among students. The cross sectional research used 139 students of Faculty of Public Health University of Indonesia. The percentage of students who is almost sleepy was 28,80%. This research showed the association between sleep duration and somnolence problem is significant (p value = 0,048). Students with sleep duration < 8 hours a day could be 0,50 times more sleepy than students with sleep duration ³ 8 hours a day. The dominant factor is sleep duration after controlled by protein and fat intake, physical activity, and media exposure. Students that frequently feels sleepy indicated low iron intake so that suggested to increase the iron intake through consuming heme contained food

Microbiological Analysis of Escherichia Coli O157:H7 on Cow\u27s Products During the Production Process

The&nbsp;problem on food health is the high amount of bacterial contamination of food served by several kinds of food sellers,&nbsp;e.g. vendors, restaurants, caterers and food industries. Meat and milk products are kinds of food prone to contamination.&nbsp;To secure food against contamination by bacteria such as E. coli O157:H7, especially related to raw food, should begin&nbsp;with the securing of products through the whole production process till it reaches the consumers. Although these&nbsp;pathogenic bacteria are part of the normal flora in the intestines of cattle, however we should be aware of the possibility&nbsp;of an outbreak in the community due to E. coli O157:H7 contamination of beef products. To anticipate the danger of an&nbsp;outbreak a study should be conducted to know about this microorganism from the beginning i.e. the production phase&nbsp;until the seller phase. The aim of this research is to know the existence of E. coli O157:H7 on beef and milk products&nbsp;obtained from abattoirs, cow ranches, traditional markets and other sellers in addition with knowing the influencing&nbsp;factors on the spreading of the microorganism. The survey design used for this research is the cross sectional design.&nbsp;The material used for the tests are 250 ml water/milk and 250 gram beef/carcass. The bacterial tests included qualitative&nbsp;tests as follows: presumptive test, confirmed test, completed test, whereas quantitatively tests as follows: Total Plate&nbsp;Cound (TPC), Most Probable Number (MPN), which is a near amount prediction of bacteria per 100 ml of water.&nbsp;Results showed that all meat (100%) coming from abattoirs and traditional markets were contaminated with E. coli&nbsp;O157:H7, in addition with most of the fresh and pasteurized milk samples (73.3%) coming from cattle ranches and home&nbsp;industries. Contamination was also found in most of the water samples (60%) and in food handlers (41.7%)
