"Bayi prematur mudah kehilangan panas, salah satunya saat dilakukan tindakan invasif pengambilan darah. Penelitian mengunakan crossover design (desain ekperimen kontrol silang) dimana melakukan 2 uji coba intervensi yang bertujuan membandingkan 2 tindakan yang berbeda pada sampel yang sama. Responden dibagi menjadi 2 kelompok A & B masing-masing 18 bayi prematur. Analisis menggunakan uji statistik independent T,test. Tindakan invasif di inkubator pintu terbuka nilai p 0,001, secara statistik terdapat perbedaan rerata yang bermakna terhadap penurunan suhu tubuh bayi prematur; sedangkan radiant warmer nilai p 0,001 secara statistik terdapat perbedaan rerata yang bermakna terhadap peningkatan suhu tubuh bayi prematur sebelum dan sesudah tindakan invasif pengambilan darah di bawah radiant warmer. Radiant warmer mampu menghindari terjadinya hipotermia pada bayi prematur saat dilakukan tindakan invasif. Radiant warmer sebagai pemancar hangat dapat direkomendasikan untuk melakukan tindakan invasif pengambilan darah, tetapi tidak digunakan untuk perawatan secara rutin karena dapat meningkatkan IWL.......The premature infants tend to heat loss quickly. It can be occurred when they get invasive procedure venous puncture. The research uses crossover design by conducting 2 intervention tests to compare 2 different treatment to the same sample. This research involves two group of respondents; A and B with consists of 18 premature infants in each group. The process of data analisys uses statistical Independent T.Test. Intervention are conducted in open incubator p value 0,001 statistically range related to heat loss in premature infants. On the other hand, radiant warmer p value 0,001 statistically refers to the defferent range of heat gain before and after invasive procedure for venous puncture is given radiant warmert. Radiant warmer prevent the premature infant from hypothermia during invasive procedure. As its benefit, it becomes the preferable way to do invasive procedure. However, it is inadvisable for routine care of newborn infant since it can increase IWL."

ABSTRACTThis paper describes the work done in order to make Matlab Simulinkbased steam generator simulator in simulation of a steam generator. The steamgenerator is operated with steam quality of 72%, O2 content is 1.2%, designsteam volume flow is 3600 barrel per day at at a maximum and design fuel gasvolume flow is 1300 MSCF per day at at a maximum.The steam generator simulation program is consisting of Burner, Radiant,Convection, Exhaust Stack, Feedwater Pump Discharge and Steam Discharge.Within the components, thermodynamics and heat transfer principles such asconduction, convection and radiation were applied to compute the pressurevalues, temperature values and flow rate values.The validation process has been done with steam generator is operating onsteady steady state and steam quality target of 72% has been achieved to the 10important process parameters of the steam generator. The error percentageresulted from simulation of Fuel Gas Orifice Differential Pressure : 2.39%, FuelGas Pressure : 1.37%, Fuel Gas Temperature : 5.95%, Fuel Gas Flow Rate :1.25%, Feedwater Orifice Differential Pressure : 1.94%, Feedwater Pressure :1.54%, Feedwater Flow Rate : 0.92%, Steam Orifice Differential Pressure 3.26%,Steam Discharge Pressure 1.93% and Steam Quality : 0.05%."
