Judul: Hubungan antara Kebiasaan Makan dengan Status Gizi pada Remaja di Perkotaan dan Perdesaan
Abstrak: Double burden of nutritional problems are not only faced by urban societies but also rural societies. This study aimed to analyze association of eating habits, physical activities and nutritional status of adolescence in urban and rural areas. The study used cross sectional design involved 102 adolescences. There were significant differences (p<0.05) between subject in urban and rural in term of age, daily pocket money, parents’ educational background, family income, family size, frequency consumption of noodles, chicken, tofu, soybean, carrot, banana, orange, physical activity of school day. There was no significant difference in frequency of a having meal and habit on buying snacks. There was significant correlation between ages, genders, parents’ educational level, family size, family income and nutritional status (TB/U), as well as gender and nutritional status (IMT/U). However, there was no significant correlation between eating habits, physical activities, energy and nutrients adequacy levels and nutritional status (p>0.05).

Judul: Hubungan Gaya Hidup dan Pengetahuan Gizi terhadap Kebiasaan Makan Remaja di Pedesaan dan Perkotaan
Abstrak: The objective of this research was to study correlation between life styles and nutrition knowledge with eating habit of rural and urban adolescent. Research design was cross sectional study.Samples were selected from adolescent of Senior High School of 10th grader at SMA Negeri 109 Jakarta Selatan and SMK Giri Taruna Jasinga, Kabupaten Bogor. Sampling was done using Simple Random Sampling. The sample consisted of 110 students. The results that the higher the smoking habit the lower the habit of buying street or junk food, the higher internet usage the higher the water consumption, and the higher the nutrition knowledge the lower the eating frequency and the water consumption.

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.
