Judul: Formulasi Bakso Ikan dengan Penambahan Tepung Tulang Ikan Bandeng untuk Ibu Hamil
Abstrak: Masalah kesehatan yang sering dialami oleh ibu hamil akibat kurangnya asupan kalsium adalah pre-eklampsia. Penelitian ini bertujuan mempelajari formulasi bakso ikan dengan penambahan tepung tulang ikan bandeng untuk ibu hamil. Rancangan percobaan yang digunakan dalam penelitian ini adalah rancangan acak lengkap dengan penambahan tepung tulang ikan bandeng sebesar 0%, 40%, 50%, dan 60% AKG kalsium ibu hamil. Penentuan formula terpilih didasarkan pada tingkat penerimaan panelis dari uji hedonik. Formula bakso ikan yang terpilih adalah F1 dengan penambahan tepung tulang ikan sebesar 40% AKG kalsium ibu hamil. Hasil uji hedonik menunjukkan terdapat perbedaan signifikan pada atribut rasa, tekstur, mouthfeel, aftertaste, dan keseluruhan. Hasil uji mutu hedonik menunjukkan terdapat perbedaan signifikan pada atribut aroma ikan, rasa bumbu, rasa ikan, tesktur, dan aftertaste. Hasil analisis sifat kimia meliputi kadar air, abu, protein, lemak, karbohidrat, dan kalsium berturut-turut sebesar 58.90-64.31% (bb), 2.50-7.77% (bb), 11.71-14.62% (bb), 3.98-4.63% (bb), 14.08-17.51% (bb), dan 75.94-857.74 (mg/100 g). Perlakuan penambahan tepung tulang ikan bandeng ke dalam bakso ikan memengaruhi kadar air, abu, protein, lemak, karbohidrat, dan kalsium. Bakso ikan bandeng ini dapat diklaim tinggi kalsium.

Judul: Pengembangan Sosis Ikan Kembung dengan Substitusi Tepung Daun Kelor sebagai Sumber Protein dan Zat Besi untuk Ibu Hamil
Abstrak: Selama masa kehamilan terjadi peningkatan kebutuhan zat gizi untuk mendukung proses tumbuh kembang janin. Sosis merupakan salah satu pangan olahan yang banyak diminati oleh masyarakat. Tujuan penelitian ini adalah mendapatkan formula terbaik sosis ikan kembung dan tepung daun kelor sebagai pangan sumber protein dan zat besi bagi ibu hamil. Penelitian ini menggunakan rancangan acak lengkap dengan rasio penggunaan ikan kembung dan tepung daun kelor yang berbeda, yaitu F1 (100:0), F2 (90:10), dan F3 (80:20). Analisis yang digunakan adalah uji organoleptik (uji kesukaan dan uji intensitas mutu), analisis fisik (tekstur dan warna), analisis proksimat, dan analisis mineral (zat besi dan kalsium). Hasil penelitian menunjukkan bahwa peningkatan tepung daun kelor secara signifikan dapat menurunkan kesukaan panelis pada atribut warna, aroma, tekstur, rasa dan keseluruhan sosis. Kadar abu, protein, karbohidrat secara signifikan meningkat sedangkan kadar air dan lemak secara signifikan menurun seiring peningkatan tepung daun kelor yang digunakan pada sosis. Sosis formula terpilih yaitu F2 (90:10) mengandung protein 17,80 gram, kalsium 100,84 mg/100 gram, dan zat besi 6,52 mg/100gram. Takaran saji sosis adalah 74 gram dan memenuhi kontribusi energi 7,8-8,2% terhadap AKG untuk ibu hamil trimester 1 sampai 3. Produk sosis F2 (90:10) telah memenuhi syarat untuk klaim sumber protein dan zat besi

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.
