Judul: Physical Activity, Body Image, and Nutritional Status of Urban Adolescents
Abstrak: Adolescents is transitional period from children to adults. In this periode there has been some rapid changes in anatomy, physiology, and psychology. The changes lead to increase of the energy and nutritional needs, but energy and nutrient intake of adolescents less than recommended daily allowance which can overcome nutritional problems in adolescents. Adolescents nutritional problems is lack of attention. The current health and nutrition progarms, only focus on children under five age and pregnant women. Whereas adolescents are in fact also the window of opportunity to solve health and nutritional problems in the world. The aim of this study were: 1) to identify the characteristic of social economy, food consumption, physical activity level, body image, BMI for age, hemoglobin level, and blood pressure, 2) to analyze the correlation between body image and BMI for age, 3) to analyze the correlation between BMI for age and sufficiency level of energy and physical activity, 4) to analyze the correlation between sufficiency level of energy and nutrient, and hemoglobin level and determinant factor of hemoglobin level, 5) to analyze the correlation between blood pressure and BMI for age The cross sectional study was conducted to 213 adolescents. The data which was collected include identities, food consumption, physical activities, body image perception, body weight, body height, hemoglobin level, and blood pressure. The data collected by using structured questionnaire. Body weight, body height, hemoglobin, and blood pressure were measured using standard methods. All of the data were processed through descriptive and inferential analysis and were presented in tables. The descriptive analysis was used to describe the variables examinded. Pearson correlation analysis was used to determine correlation coefficients between ratio variabels. Chi square analysis was used to determine correlation coefficients between nominal variabels. A Stepwise regression was to determine the determinant factor of hemoglobin level. A p-value < 0.05. The results showed that the urban adolescents had a very low level of physical activity (51.6%). Very low level of physical activity is the one cause of high prevalence of overweight (16.9%) and obese (6.1 %) in urban adolescents. There were positive correlation between overweight and obesity, and systolic blood pressure (r= 0.310; p= 0.000) and diastolic bolod pressure (r=0.168; p= 0.014). The most of adolescents have a negative body image perception (41.8%), mostly occuring in girl adolescents (53.6%). Energy, protein, vitamin C, and iron intake were less than recommended daily allowance. Low intake of iron cause of high prevalence of anemia (26.3%), due to impaired of hemoglobin synthesis. The determinant factor of hemoglobin level were sufficiency level of iron and sufficiency level of protein. This implies that nutrition education advocacy in formal school is important to improve their nutrition knowledge, including the importance of various of food consumption, vitamins and minerals, physical activity, and positive body image perception.

Judul: Food habits and physical activity in relation to the nutritional status of adolescents in urban and rural senior high schools in Bogor.
Abstrak: Adolescences are one of the most exciting but still challenging periods in human development. Most adolescents are the periods of life that occurs between 12 and 21 years of age, adolescence is a period of tremendous physiologic, psychologic, and cognitive transformation during which a child becomes a young adult. Adolescent food habits and physical activity patterns are an important concern in the present accelerated nutrition transition. Healthy food choices combined with regular physical activity help to prevent a variety of chronic diseases such as obesity, high blood pressure, high blood cholesterol, diabetes, heart disease, and certain cancers. The objective of this study was to identify the description of eating habits, breakfast skipping, frequent snacking and about the behavior of money management, to Analyze the adequacy of macro and micronutrients, to analyze the nutritional status, to analyze the physical activity level, to analyze the relationship between pocket money versus the family income, family size, food habits including eating habits, breakfast habits, snacking habit and food preferences, and convenient foods. This study was used in a cross-sectional study design and This study was used in a cross-sectional design and the location of the research was the two public high schools in Bogor, SMA Negeri 3 Bogor, Baranangsiang, East Bogor, Bogor city and SMA 1 Leuwiliang, Leuwiliang, Bogor, West Java, Indonesia and the place of the research was selected purposively. The subjects’ study was the students of urban and rural senior high schools in Bogor. The subjects were grade 10th, 11th, and 12th students as well as willing to participate in the study and their age ranges between 10-19 years. Finally, the total number of the subjects of this study were 70 students aging with 16-19 years old. Primary data is obtained through measurement techniques and direct interviews and using a questionnaire. Primary data include: 1) subject characteristics (age, sex, and amount of pocket money), food habits (eating habits, breakfast habits, and snacking habits), food preferences and convenient foods, 2) Family socio-economic characteristics (education, employment, and parents’ income), 3) physical activity level using one day physical activity recall, 4) food recall for 2x24 hour, 5) Anthropometric characteristics (body weight) were obtained from direct measurements using digital scales and height was measured using a stature meter. Based on the results of this study, the average ages of the students were 16-19 years. The majority of urban and rural families were medium-sized families. Based on the results of the study, the majority of the parents from the urban area were finished graduate school while the parents from the rural area were finished high school. The urban subjects had better nutritional status than rural subjects, with 80.0% of urban adolescents having normal nutritional status while 57.1% of rural adolescents have normal nutritional status. Most of the urban adolescents, 45.7% they take their breakfast between 05:00-06:00 whereas the majority of rural adolescents, 54.3% they take their breakfast between 06:00-07:00. Also, the results iii indicated that most of the adolescents both from the urban and rural, they have breakfast before leaving for school, only about 5.7% of urban adolescents and

Judul: Lumut Suku Dicranaceae Khususnya Dicranoloma di Taman Nasional Gunung Leuser (Sumatra)
Abstrak: Lumut merupakan kelompok tumbuhan yang tidak memiliki berkas pembuluh. Tumbuhan ini memiliki peranan sebagai indikator kelembapan dalam ekosistem hutan. Dicranaceae merupakan kelompok lumut sejati yang umum ditemukan di hutan hujan tropis dataran rendah hingga hutan hujan pegunungan. Dicranoloma merupakan salah satu marga yang termasuk ke dalam suku Dicranaceae. Marga ini mudah dikenali di lapangan berdasarkan daunnya yang panjang dan kosta yang menyempit. Keanekaragaman jenis Dicranoloma yang telah dilaporkan di Sumatra hanya setengah dari total jenis yang diketahui berada di Malesia. Hal ini menunjukkan bahwa keanekaragaman Dicranoloma masih sedikit dilaporkan di Sumatra. Meski demikian, kawasan hutan hujan tropis di Sumatra telah berkurang karena perubahan penggunaan lahan. Taman Nasional Gunung Leuser (TNGL) merupakan kawasan konservasi yang menyediakan perlindungan bagi jenis tumbuhan termasuk lumut sejati. Oleh karena itu penelitian ini dilakukan untuk mengeksplorasi dan mencatat keanekaragaman Dicranaceae khususnya Dicranoloma TNGL dalam melengkapi daftar jenis lumut sejati Sumatra. Spesimen lumut sejati dikoleksi di sepanjang jalur pendakian di Gayo Luwes dari Rainforest Lodge Kedah hingga Puncak Angkasan di TNGL (1417-2925 mdpl). Spesimen di Herbarium Bogoriense (BO) juga diamati untuk melengkapi informasi yang dibutuhkan selama penelitian ini. Karakter morfologi pada fase gametofit dan sporofit digunakan untuk membuat kunci identifikasi dan deskripsi jenis yang tercatat di TNGL. Sebanyak 25 jenis Dicranaceae ditemukan di TNGL. Lumut tersebut tumbuh pada substrat yang bervariasi yaitu pada tanah, kayu lapuk, batang dan cabang pohon. Marga Dicranoloma memiliki variasi pada karakter gametofit yaitu perawakan (tegak atau menggantung), unting pusat pada batang (ada atau tidak), permukaan batang (rambut menggimbal banyak, rambut menggimbal sedikit, atau tidak ada rambut menggimbal), daun (bentuk, tepi ujung daun, ketebalan dinding sel alar, kehadiran papila pada abaksial kosta). Daun berbentuk membundar telur-melanset, menyegitiga, dan melanset. Tepi ujung daun halus, bergigi, dan bergigi ganda. Sel alar berdinding tipis atau berdinding tebal. Abaksial kosta dengan atau tanpa papilla. Variasi karakter sporofit yang diamati pada marga ini adalah jumlah seta tiap perikaetium, orientasi dan bentuk kapsul. Jumlah seta yaitu satu, dua atau enam tiap perikaetium. Kapsul menyilindris atau menyilindris-melengkung, tegak atau tercondong masuk. Terdapat 10 jenis Dicranaceae yang diketahui sebagai catatan baru untuk Sumatra yaitu Braunfelsia enervis, Braunfelsia edentula, Campylopus austrosubulatus, Dicranodontium asperulum, Dicranodontium uncinatum, Dicranoloma dicarpum, Dicranoloma eucamptodontoides, Dicranoloma rugifolium, Ditrichum flexicaule, Leucoloma amoene-virens, dan Dicranoloma sp. Jenis terakhir mirip dengan D. assimile tetapi berwarna kekuningan, tidak memiliki rambut menggimbal dan unting pusat. Tiga jenis catatan baru Dicranoloma menambah jumlah jenis Dicranoloma di Sumatra yang sebelumnya diketahui berjumlah tujuh jenis yaitu D. assimile, D. blumii, D. billardieri, D. braunii, D. brevisetum, D. daymannianum dan D. reflexum. Dicranoloma dicarpum sebelumnya hanya dilaporkan di New Guinea, Australasia dan Taiwan. Persebaran Dicranoloma eucamptodontoides sebelumnya mencakup Australia dan New Zealand sedangkan Dicranoloma rugifolium dilaporkan hanya dari New Guinea.
