Abstrak: Diabetes Mellitus (DM) is a metabolism disorder disease signed by increasing of blood glucose (hyperglicemia) caused by insulin secretion disorder and or increase of insulin resistance. The purpose of this study was to develop a coffee product containing mahogany seeds (Swetenia mahagoni Jacq.) with good sensory as a fungtional drink for diabetic. Coffee product with the addition of 100 mg mahogany seed extract/serving size or 0.7% was chosen product (P<0.05). The selected coffee has water solubility 97.38% and bulk density 0.4854g/mL. The selected coffee contained 2.80% moisture, 5.88% ash, 1.08% fat, 6.04% protein, 84.20% carbohydrate, 0.96% total dietary fiber, 7.48% caffeine, and toxicity values347.097 ppm. GCMS analysis showed that selected coffe was contained Dodecanoic acid, 1,2,3 esters - propanetriyl, Octanoic acid , 1,2,3 - propanetriyl ester, and Esther Dodecanoic acid, 1 - ( hydroxymethyl ) -1.2 - ethanediyl. Based on this study it can be concluded that coffee with the addition of mahogany seed extract can be used as an alternative functional drink for diabetic

Abstrak: Degenerative disease such as diabetics requires safe and long-term medical treatments. The aim of this study was to measure blood glucose and liver glycogen status of 15 alloxan-induced Wistar rats which allocated into three groups, namely: (1) mahagony coffee group which had an intervention of coffee beverage with addition of mahogany seed extract, (2) coffee group which had an intervention of coffee beverage without addition of mahogany seed extract, and (3) control group which had no intervention of any coffee beverage. After 21 days of intervention, blood glucose level of control group changed positively, whereas blood glucose level of coffee group and mahagony coffee group changed otherwise. The intervention had an significant difference (p<0.05) to blood glucose level of rats. Blood glucose level of control group was significant difference (p<0.05) with coffee group and mahagony coffee group Nonetheless, blood glucose level between coffee group and mahagony coffee group was no significant difference (p>0.05). Moreover, the 21 days of intervention was given no significant difference (p>0.05) to liver glycogen level.

Judul: Analisis Siklon Tropis Narelle 2013 Menggunakan Model WRF
Abstrak: Narelle is a tropical cyclone which started on January 8 and decayed on January 14 2013 and took place in the Southern Hindia Ocean near the Nusa Tenggara Timur to the west of Australian coasts. The objective of this research is to analyze the relationship of surface heat flux with a cyclones Narelle 2013. The strength of relationship between surface heat flux and Narelle cyclone parameter is evaluated using a correlation coefficient. WRF model is, then, utilized to generate meteorological parameters which are responsible in the formation of the cyclone at its earliest stage. The parameters include pressure, surface sensible heat flux, surface latent heat flux, wind speed and SST. The result shows that surface latent heat flux is related to SST in the formation of Narelle cyclone with correlation coefficient of 0.89 and surface sensible heat flux is related to the wind speed with a correlation coefficient of 0.88
