Judul: Profil Protein Terlarut Pada Berbagai Pelarut Dari 7 Macam Kacang-Kacangan
Abstrak: Long bean, soybeans, komak peanuts, green snap beans, nuts gude, cowpea, and green beans are 7 kinds of nuts are often used as processed food in Indonesia. This study examined the soluble protein profiles of 7 kinds of nuts. Determination of nutrient content was generally done by including proximate analysis. Determination of soluble protein performed by the method of Bradford. SDS polyacrylamide gel electrophoresis was used to determine the pattern and the molecular weight of 7 different protein samples. Determination of amino acid content was done using HPLC. The protein content is generally based on Kjeldahl method of bean protein content nuts gude at 35, 23%, soybeans at 28.13%, long bean at 24.84%, green snap beans at 23.74%, cowpea at 19.66%, komak peanuts at 19.57%, and green beans at 19.19%. SDS PAGE results showed there were 9 long bean protein bands with MW 16.84 - 109.61 kDa, there are 5 bands soybeans protein with MW from 12.04 - 64.44 kDa, nuts komak there were 10 protein bands with BM 17.32 -112.72 kDa, green snap beans there are 14 protein bands with MW 13.09 - 153.31 kDa, there are 7 nuts gude protein bands with BM 12.38 - 62.66 kDa, cowpea with 14 protein bands with MW 13,84 - 149.08 kDa, and green beans are 16 protein bands with MW 13.09 - 157.66 kDa.

Judul: Legumes Consumption Among Indonesian Population Aged 19 to 55 Years Old
Abstrak: Kacang-kacangan dapat berpotensi menjadi salah satu sumber protein berkualitas karena mengandung proporsi lemak tidak jenuh yang tinggi. Penelitian ini bertujuan untuk menganalisis konsumsi kacang-kacangan penduduk Indonesia usia 19 hingga 55 tahun berdasarkan hasil Survei Konsumsi Makanan Individu (SKMI) dari rangkaian Studi Diet Total (SDT) 2014. Desain penelitian yang digunakan adalah deskriptif kuantitatif dengan total subjek sebesar 78.376 orang. Uji independent sampel t-test digunakan untuk melihat perbedaan konsumsi kacang-kacangan, asupan energi dan protein serta kontribusinya dengan karakteristik individu. Konsumsi kelompok kacang-kacangan yang paling banyak dikonsumsi adalah kacang kedelai dan olahan (42,96 g/kap/hari) dengan tingkat partisipasi 81,8% Diikuti dengan konsumsi kacang tanah dan olahan (1,99 g/kap/hari), kacang lainnya dan olahan (0,89 g/kap/hari), dan konsumsi paling rendah adalah biji-bijian dan olahan (0,52 g/kap/hari). Berdasarkan golongan usia, rata-rata asupan energi dan protein dari kacang-kacangan usia 40-55 tahun lebih tinggi dibandingkan usia 19-39 tahun (p<0,05). Rata-rata asupan energi dan protein juga diketahui lebih tinggi pada laki-laki dibandingkan perempuan (p<0,05). Berdasarkan klasifikasi wilayah, rata-rata asupan energi dan tingkat kontribusi kacang-kacangan di perkotaan lebih tinggi dibandingkan di pedesaan., Legumes can potentially be a source of quality protein because they contain a high proportion of unsaturated fats. This study aims to analyze the consumption of legumes by Indonesian population aged 19 to 55 years old based on the results of the Dietary Assessment of Individual Level (DAIL) from the Total Diet Study (TDS) 2014. The research design applied a descriptive quantitative with a total of 78,376 subjects. Independent sample t-test was applied to analyze differences in consumption of legumes, energy protein intake, and their contribution to subject’s characteristics. Consumption of the most consumed group of legumes was soybeans (42.96 g/cap/day) with a participation rate of 81.8%. Followed by the consumption of peanuts (1.99 g/cap/day), other nuts (0.89 g/cap/day), and the lowest consumption was seeds (0.52 g/cap/day). Based on age group, the average intake of energy and protein from legumes aged 40-55 years old was higher than the subject aged 19-39 years old (p<0.05). The average intake of energy and protein is also to be higher in males than in females (p<0.05). Based on the area classification, the average energy intake and contribution level of nuts in urban are higher than in rural.

Judul: Pengaruh vaksinasi terhadap dinamika populasi pada model SIR (Susceptible-Infected-Recovered)
Abstrak: SIR model can be used to model the spread of diseases in a closed population based on certain assumptions. In this research, the SIR model is formulated by including the factor of vaccination. As the result, the model has been shown to have two equilibrium points, i.e. disease free and endemic equilibrium. A simulation study is carried out to illustrate the model. The results show that some equilibrium points are asymptotically stable. Moreover, a minimum level of vaccination has been defined. For the vaccination level less than the minimum level, increase in the vaccination level results in decrease of the proportion of infected individuals in the corresponding equilibrium point. On the other hand, for the vaccination level greater than the minimum level, increase in the vaccination level results in decrease the proportion of susceptible individuals in the corresponding equilibrium point. Furthermore, when vaccination level is greater than the minimum level, it is found that the time needed for the disease to extinct is shorter.
