Abstrak: Yellow pumpkin (Cucurbita moschata) is one of vegetables plant that is potential to be developed as food alternatives. However, the consumption of yellow pumpkin in Indonesia is still low, that is 5 kglcapitalyear and the utilization is stiII limited as for meal, kolak or dodol. This is quite different if we compare it to the other countries that are used for jam, sweetener, jelly, pie and cake. So in Indonesia, it is needed much more researches to develop the utilization of yellow pumpkin. One of the most important researches is how to take advantage of its food fiber. The purpose of this research is to determine the suitable formula to produce an instant fiber beverage powder product that is suitable to consumer's preference. This research consists of two phases, preliminary and primary phase. Preliminary phase consists of the determination of substances that is combined with yellow pumpkin as food fiber sources, the determination of initial formula, organoleptic test, and initial analysis on each substance. As for primary phase, it consists of the determination of beverage powder formula, beverage powder production, organoleptic test, and beverage powder physical-chemical analysis.

Judul: Pengembangan Mi Glosor Instan dari Tepung Sagu Aren dengan Substitusi Tepung Labu Kuning sebagai Alternatif untuk Diversifikasi Pangan
Abstrak: “Mi Glosor” is quite attractive to community in the area of Cianjur, Sukabumi and Bogor. Mi Glosor is a kind of noodle made from sagoo flour and therefore it is high in carbohydrates but very low in protein, fat and other nutrients contents. Mi Glosor is usually sold in wet conditions which make its shelf life very limited. Pumpkin is a potential food resources with high production capacity in Indonesia. It’s use in the manufacturing of mi glosor may function as a natural coloring and may increase nutritional content, especially beta-carotene. The purpose of this study was to develop instant noodle “mi glosor” using pumpkin flour as coloring agent and beta-caroten source. Pumpkin flour was used to substitute basic ingredients in the manufacturing of instant noodle “mi glosor”. Substitution levels were applied from 0% to 40%. To increase it’s protein content in order to meet the instant noodle standard, 5% of soy protein isolates was added to each formula. Substitution of pumpkin flour significantly (p<0.01) affected ash, protein, fat and beta caroten content, but there was no effect on water and carbohydrate content of the product. Physical analysis showed that substitution of pumpkin flour tended to cause the value of Luminant and Hue of the product declined. Substitution of pumpkin flour also shortened the cooking time of the product. The result of sensory analysis showed that the formula with 30% substitution of pumpkin flour was the most acceptable product. This formula had medium yellownes color, caramel and pumpkin flavour and medium elasticity. This formula also contained 408 μg/100mg betacaroten, 4,84 % water, 3,27 % ash, 3,71 % protein, 0,11 % lipid and 88,05 % charbohydrat.

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.
