Judul: Daging Artifisial Zat Besi sebagai Alternatif Pangan Vegetarian Pencegah Anemia.
Abstrak: Vegetarian merupakan kelompok rentan terhadap risiko anemia. Hal ini disebabkan oleh rendahnya penyerapan zat gizi besi dalam bentuk non heme. Tujuan dari penelitian ini adalah menghasilkan formula daging artifisial melalui pemanfaatan tepung ubi (Ipomoea batatas L) untuk mengurangi penggunaan tepung gluten serta tinggi kandungan zat besi sebagai alternatif pangan vegetarian pencegah anemia. Penelitian ini merupakan eksperimental studi dengan rancangan acak lengkap. Formula terpilih didasarkan atas beberapa kriteria keputusan yakni nilai keseluruhan hedonik (kesukaan), bioavailabilitas Fe dan biaya produksi. Kandungan gizi formula terpilih per 100g yaitu 63.22g air, 0.39g abu, 21.39g protein (sumber protein), 0.07g lemak (rendah lemak), 14.95g karbohidrat dan 8.44mg zat besi (tinggi besi). Nilai bioavailabilitas besi produk sebesar 28.83% (setara 2.43mg) dan diharapkan dapat dijadikan sebagai alternatif pangan vegetarian pencegah anemia gizi besi.

Judul: Fortifikasi Mikroenkapsulasi Besi pada Biskuit Tepung Komposit Pisang, Ubi Jalar, Tempe, dan Wortel sebagai Pencegah Anemia Defisiensi Besi
Abstrak: Penelitian bertujuan untuk manghasilkan biskuit berbahan dasar tepung pisang, ubi jalar, tepung tempe, dan tepung wortel dengan fortifikasi mikroenkapsulasi Fe untuk menanggulangi masalah anemia defisiensi besi. Pembuatan biskuit menggunakan bahanbahan lokal dengan metode dry mixing sebagai upaya diversifikasi pangan. Mikroenkapsulasi Fe dilakukan dengan teknik spray drying yang berbahan dasar ferrous sulphate heptahydrate dengan maltodekstrin dan gum powder sebagai penyalut. Jumlah mikrokapsul besi yang ditambahkan yaitu sebesar 33%, 35%, 37% AKG zat besi usia anakanak 7-9 tahun untuk mencapai klaim tinggi besi. Formula terpilih berdasarkan skor ranking berdasarkan nilai mutu organoleptik. Kandungan gizi formula terpilih yaitu 1.80% air, 2.81% abu, 14.00% lemak, 9.13% protein, 55.84% karbohidrat, dan 8.3 mg/100 gram zat besi (tinggi besi). Nilai bioavailabilitas zat besi dari biskuit sebesar 20.00% (tinggi biavailabilitas). Biskuit dengan fortifikasi mikrokapsul besi diharapkan dapat dijadikan sebagai pangan alternatif pencegah anemia defisiensi besi.

Fortification of Iron Microencapsulated to composite flour from banana, sweet potato, soybean, and carrot as an alternative food to prevent iron deficiency anemia. Supervised by EVY DAMAYANTHI. The objective of this research was to create a biscuit flour-based from sweet potato, banana flour, soybean flour, and carrot flour with iron microencapsulated fortification to prevent the problem of iron deficiency anemia. The method for this research were making biscuits using local ingredients with dry mixing method, iron was microencapsulated using maltodextrin and gum powder as the coating materials by the spray drying technique, and iron bioavailability of biscuit measured by dialysis bag. The amount of iron microencapsulated was added about 33%, 35%, and 37% from iron RDA of children’s aged 7-9 years old to achieve food with high iron content. The selected formula’s score was 74% of panelist accept the biscuit based on the score ranking of the organoleptik quality. Contributions of biscuits towards energy sufficiency and iron seen from the proximate test. Nutrient content of the best formula were 1.80% of water, 2.81% of ash, 14.00% of fat, 9.13% of protein, 55.84% of carbohydrate, and 8.3 mg/100 g of iron (high iron). The iron bioavailability was 20.00% (high bioavailability). Biscuit with iron microencapsulation can be used as an alternative food to prevent iron deficiency anemia, because every serving size contain 4.15 mg iron which has a claim to food with high in iron.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
