Judul: Karakteristik keripik simulasi tepung Lindur (Bruguiera gymnorrhyza) dengan penambahan tepung kepala Udang Vaname (Litopenaeus vannamei)
Abstrak: Buah lindur (Bruguiera gymnorrhyza) merupakan salah satu kearifan lokal yang pemanfaatannya masih belum optimal sebagai alternatif bahan pangan dengan kandungan karbohidrat tinggi. Oleh karena itu, buah lindur dapat dimanfaatkan sebagai bahan membuat produk pangan yang berbasis karbohidrat salah satunya adalah keripik. Namun keripik perlu diperkaya dengan bahan lain untuk dapat memenuhi gizi tertentu. Udang merupakan salah satu produk perikanan yang sangat potensial dalam perdagangan internasional. Udang umumnya diekspor dalam bentuk tanpa kulit dan tanpa kepala (peeled) sehingga menghasilkan hasil samping berupa kepala dan kulit udang yang masih mengandung gizi yang masih dapat dimanfaatkan sebagai bahan pangan. Hasil samping tersebut bisa mencapai 35-40% bobot tubuhnya. Salah satu udang yang sangat potensial adalah udang vaname (Litopenaeus vannamei). Keripik simulasi merupakan salah satu cara pengolahan pangan untuk dapat menghasilkan produk camilan yang dapat memenuhi kandungan gizi tertentu. Pembuatan keripik simulasi dengan cara pengadonan memungkinkan adanya penambahan bahan tertentu untuk memperkaya kandungan gizinya. Dalam penelitian ini keripik simulasi dibuat dengan basis komposit tepung lindur dan ubi kayu dengan penambahan tepung kepala udang vaname sebagai pengaya gizi terutama protein., Bruguiera gymnorrhyza known as lindur is the local fruit that its utilization as alternative for substitution of food material high in carbohydrate is not yet optinal. Therefore, the fruit can be utilized as an ingredient for making chips. But the chips in the simulation needs to be done to meet the enrichment of certain nutrients. Shrimp is one of the very potential of fishery products in international trade. The shrimp were exported in form of product without skin and without head (peeled) resulting in a waste of skin and shrimp heads that still contains nutrients that can still be exploited as food ingredients. The weights so that waste can reach 35-40% of its body weight. One of the very potential shrimp is vaname shrimp (Litopenaeus vannamei). Simulated chips were one of food processing that can produce snack product that contain of certain nutrition. Simulated chips were made from dough that can be added by certain nutrition as enrichment. Therefore simulation chips were made from lindur flour and steamed cassava with addition of vaname shrimp head flour to increase its protein content.

Judul: Optimasi Produksi Keripik Simulasi dari Ubi Kayu (Manihot esculante Crantz.) dan Ubi Jalar (Ipomea batatas L.) Bersuplementasi Protein Tepung Kedelai dan Tepung Beras
Abstrak: Indonesia memiliki beragam jenis tanaman umbi-umbian dengan produksi melimpah, contohnya ubi kayu dan ubi jalar. Namun pemanfaatan kedua jenis umbi ini menjadi makanan olehan terntama yang dapat dikembangkan dalam skala industri masih amat terbatas. Altematif pemanfaatan ubi kayu dan ubi jalar menjadi produk makanan olahan yang dapat dikembangkan dalam skala industri adaJah pembuatan keripik simulasi. Keripik simulasi umumnya dibuat dari tepung ubi. Namun dengan suplementasi protein tepung kedelai dan tepung beras, dapat dibuat kelipik simulasi langsung dari ubi yang dikukus dan digiling, sehingga dapat menghemat waktu dan biaya produksi. Hasil penelitian menunjukkan bahwa keripik simulasi dari ubi kukus-giling ini lebih disukai dibandingkan keripik simulasi dari tepung ubi.

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.
