Judul: Formulasi Bubur Susu Instan dengan Penambahan Tepung Kelor (Moringa oleifera) sebagai Makanan Tambahan bagi Kelompok Rentan Gizi
Abstrak: Penelitian ini bertujuan untuk melakukan formulasi bubur susu instan dengan penambahan tepung kelor sebagai makanan tambahan bagi kelompok rentan gizi. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL). Berdasarkan hasil uji organoleptik pada bubur susu instan tepung kelor didapatkan formula terpilih yaitu F4 dengan penambahan tepung daun kelor 15 g. Formula terpilih memiliki nilai densitas kamba sebesar 0.4884 dan membutuhkan 0.8 ml air/g bubur untuk melarutkan dengan waktu rehidrasi selama 36.5 detik. Hasil analisis kandungan gizi pada produk terpilih didapatkan dalam 100 g bubur susu instan mengandung energi 387 kkal, kadar protein 12.07 (% bk), kadar lemak 9.15 (% bk), karbohidrat 64.08 (% bk), zat besi 38.2 mg/100 g dan kalsium 417.15 mg/100 g. Berdasarkan hasil analisis kandungan gizi, bubur susu dapat di klaim sebagai bubur tinggi protein (7-23 bulan), sumber protein (2-5 tahun dan umum), tinggi zat besi (7-23 bulan dan 2-5 tahun) dan tinggi kalsium sesuai dengan persentase terhadap Acuan Label Gizi (ALG) dalam 100 g bahan makanan (dalam bentuk padat).

Judul: Formulasi Sereal Instan Berbasis Tepung Sorgum dan Kacang Hijau dengan Penambahan Tepung Torbangun untuk Wanita Post-Partum
Abstrak: Penelitian ini bertujuan untuk mengembangkan suatu produk sereal instan berbasis tepung sorgum dan tepung kacang hijau dengan penambahan tepung torbangun sebagai produk pangan fungsional bagi wanita post-partum atau ibu menyusui. Rancangan percobaan yang digunakan dalam penelitian ini adalah rancangan acak lengkap dengan faktor berupa jenis formula. Hasil uji organoleptik menunjukkan bahwa formulasi bahan yang dilakukan pada pembuatan produk menyebabkan perbedaan yang signifikan terhadap kesukaan panelis terhadap atribut warna, rasa, tekstur, dan overall (p<0.05). Penentuan formula terbaik dilakukan dengan menggunakan uji hedonik dan pertimbangan substitusi dari tepung sorgum. Formula F3 dengan perbandingan tepung sorgum dan kacang hijau 50:50 memiliki tingkat kesukaan tertinggi dengan persentase penerimaan sebesar 89%. Kandungan gizi sereal instan formula terpilih untuk air, abu, protein, lemak, karbohidrat, kalsium, dan zat besi secara berturut-turut adalah 6.29 g, 3.68 g, 14.5 g, 2.69 g, 73.31 g, 268.24 mg, dan 9.42 mg per 100 gram bahan. Skor asam amino pada produk sereal instan telah mencapai skor maksimun yaitu 100 dengan asam amino pembatas metionin dan sistin. Sereal instan flakes formula terpilih mengandung energi sebesar 375 Kal/100 gram.

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.
