Judul: Gaya hidup murid SD IPEKA Sunter Jakarta Utara yang berstatus gizi normal dan lebih
Abstrak: The objectives of this study were to identify elementary students life style between the normal and overweight/obese nutritional status. Life style means physical activities and eating habits. Cross sectional study design was applied in this study and sample were drawn by purposive sampling. Data collected using a questionnaire and also with the observations. Eating habits explained by habit for breakfast, consumption of vegetables and fruits, snacking, fast food and soft drink, milk and water drinks. Physical activities were explained by how long students were watching television, playing games / computer, light activities such as sit and stand, medium activities such as jogging and walking or household activities, and heavy activities such as sport activities. Result shows that individual and family characteristics of the two samples are almost similar, likewise the eating habits and the physical activities. Independent sample t test show that there are significantly differences between their fast food consumption, breakfast frequency, parents nutritional knowledge, parents nutritional status, and exercise habit (P<0.05).

Judul: Asupan Energi, Zat Gizi dan Serat serta Aktivitas Fisik Siswa Sekolah Dasar Berstatus Gizi Lebih di Kota Bogor
Abstrak: This study were aimed to analyze energy, nutrient intake and physical activity of overweight and obese elementary school student and correlation between energy, nutrient intake, physical activity and family characteristics of students with nutritional status BMI/U. A cross sectional study of 99 subjects was conducted. The intake of energy, protein, fat and carbohydrate was 1777 kcal, 57 g, 53 g and 340 g. Most of the students were deficit of energy, fat, calcium, phosporus, vitamin A, vitamin C and fiber, while protein, carbohydrate and iron were adequate. Physical activity levels of students classified mostly light or sedentary activity. There was no significant relationship between energy and macronutrients intake with BMI/U (P> 0.05). There was a significant correlation between the nutritional status of IMT/U with a family income level, father's education and maternal education (p<0.05).

Judul: Sintesis 6-Bromo-4-O-metilkoniferil Alkohol dan trans-Sinamat-nya sebagai Prekursor ke Analog Podofilotoksin
Abstrak: Podofilotoksin merupakan lignan utama dalam resin podofilin yang diekstraksi dari tumbuhan Podophyllum. Toksin ini memiliki aktivitas antivirus, antitumor, antijamur dan antikanker. Berbagai upaya menyintesis podofilotoksin secara kimia telah banyak dilaporkan. Eugenol yang memiliki kerangka fenilpropena dapat digunakan sebagai bahan awal untuk sintesis podofilotoksin berdasarkan keberadaan kerangka dimer fenilpropanoid. Penelitian ini bertujuan menyintesis prekursor untuk sintesis analog podofilotoksin, 6-bromo-4-O-metilkoniferil alkohol dan ester trans-sinamat-nya, dari bahan awal eugenol. Senyawa alkohol target berhasil disintesis dalam 3 tahap, yaitu brominasi, dehidrobrominasi-substitusi, dan hidrolisis, dengan rendemen keseluruhan 34% dari tribromida metileugenol. Sementara produk ester trans-sinamat belum dapat ditentukan rendemennya karena belum semua fraksi dapat dimurnikan sebagai akibat dari pandemi Covid-19. Isomerisasi asam trans-sinamat dan esterifikasi isomer-cis yang diperoleh dengan 6-bromo-4-O-koniferil alkohol serta penuntasan pemurnian ester trans-sinamat merupakan rencana pekerjaan selanjutnya.
