No full textThis research discusses about action and research learning model. The research’s purpose is to describe the activity and learning achievement of Guided Inquiri Model which is integrated with multirepresentation approach.in SMA class X IPA 5 during odd semester in 2015/2015. This learning model can be effective if: the learning objectives are achievable, the students’ activities in active to very active criteria, the improvement of learning achievement in low to high criteria. This research is an action research, so the research is done by action research method. Design of this research is using Hopkins cycle. Data collection technique of this research are documentation, observation, test, and interviews. The data analysis used N-gain. The most effective about this model is when used in first cycle, with learning activities are about 71,1% - 89,5% for each indicators. Students’ activities in this cycle are included in active to very active. The improvement of learning achievement (N-gain) in this cycle is 0,33 and 0,35, that included in middle criteria

PENGARUH LAMA PERENDAMAN TiO2 DALAM DYE SENSITIZER EKSTRAK DAUN TEMBAKAU (Nicotiana tabacum L) TERHADAP EFISIENSI DYE SENSITIZER SOLAR CELL (DSSC)
Get PDFEnergy is one of the important things in the world, especially Indonesia,which has high people population. Energy consumption are dominate ofunrenewable energy, such as fuel and gasses. In other side, unrenewable energy wasrestricted, so we need to find the other energy source. Renewable Energy can helpsUnrenewable energy to complete national energy consumption such as solar cell.DSSC (Dye sensitized solar cell) is a kind of inexpensive and eco-friendly solar cellthat base on photoelectrochemical reaction. The purpose of this research is toobserve the affect of TiO2 immersion in tobacco leaf extract (Nicotiana tabacum L)as dye sensitizer to current, voltage and eficiency of Dye Sensitized Solar Cell(DSSC). The stage of this research are dye preparation, counter-electrodepreparation, TiO2 preparation, electrolyte and assembly process. The variable thatuse in this research are 30 minutes, 60 minutes, and 90 minutes of immersion time.The result indicate that the immersion hasaffect to DSSC output. The 60 minutes ofimmersion can result higher output at 12 P.M with 729,2 Watt/m2 illuminance,which are 173,6 mV in voltage and 0,621 mA in current. It also produce 0,0493%efficiency at the same time. The result indicate that the immersion hasaffect to DSSCoutput such as current, voltage and efficiency
PENGARUH KONSENTRASI LARUTAN TERHADAP LAJU KENAIKAN SUHU LARUTAN
Get PDFEffect of Solution Concentration Solution Temperature Rise Against The pace of research that observing and measuring about concentration and the rate of temperature rise of the solution. A liquid will boil when the molecules gain enough energy to liberate themselves from fellow molecule that then turns into steam. When other substances dissolved in water, the substance of these substances will be particles, which later these particles would bind particles of water and escaping into vapor, in other words, the water molecules will require higher energy to boil. The time it takes to boil the solution varies depending on the size and type of solute concentration. This study aimed to investigate the relationship concentration versus time solution temperature increases 50o C, and assess the effect of concentration versus time solution temperature increases 50o C.

OPTIMALISASI DAYA KERJA OTAK MELALUI PEMANFAATAN STIMULAN EKSTERNAL
Get PDFHumans have many privileges compared to other living beings. One of thesefeatures is the human brain endowed with superior working power. The human brain is asystem control center of all his activities, whether the activity is done consciously oractivities conducted under awareness. Modern research shows that the human braincontains one trillion cells, which includes 100 billion active nerve cells (neurons) and 900billion other cells that glue, maintain and envelops the neurons. The ability of the brainmemory can reach the order of 10800, is much greater than the capacity of moderncomputer hard drive which is at the order of 1012. There are two realities about theworkings of the brain : (1) Rapidly growing brain power into the teenage years and thenthe momentum gradually decreases, and (2) power of the brain to be more efficient if thebrain is more widely used and trained. The brain has a sensitivity to specific things, whichis the color, sounds and fragrances stimulation. Therefore, efforts to improve the workingsof the brain can be done by providing the right external stimulants. This effort can berealized through the use of painting, music, and fragrances are integrated with the balanceof brain exercises that vary. Brain power of good to help people to be able to think,analyze, imagine and store information optimally
