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: Daya Terima Konsumen dan Kandungan Gizi Daging Analog Berbasis Tepung Gluten dan Tepung Ubi Jalar yang Difortifikasi Zat Besi
Abstrak: Most of vegetarians are at risk of anemia iron deficiency because their non heme iron foods are absorbed lower in body. Analogue meat fortified with iron was made for preventing anemia. The aim of this study was to know a consumer acceptance and nutrients content of analogue meat based on gluten flour and sweet potato flour fortified with iron. The best product was decided by Comparisson of Matrix Exponential Methods with organoleptic test and processing cost consideration. Water content of this product was 59.38% (wb). This analogue meat contained of ash 5.68% (db), protein 32.44% (db), fat (db) 9.03%, carbohydrate 52.84% (db), energy 422.44 Kal (db), and iron 6.44 mg/100 g (db) with bioavaibility 27.43%. Essential amino acid contents of this product, histidine 20.61 mg/g protein was adequate for a day. Hardness and water hold capacity of raw analogue meat and cooked analogue meat were not significantly different (p>0.05). Thirty vegetarian consumer panels accepted this product more than 73.33% based on acceptance consumers test. In a day, portion that served was three slices meat (70 g) provided energy 119.88 Kal, protein 8.87 g, fat 2.47 g, carbohydrate 15.54 g, iron 1.76 mg. Iron content of this product covered 13.57% of men requirement (age 19–64) and 6.77% of women requirement (age 19–49).

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.
