Get PDFThe aim of this research are: (1) To study differences students’ physics achievement between which used problem-based learning model by issue discourse analysis and used direct instruction model (conventional) and (2) To describe of students’ learning activities by using problem-based learning model by issue discourse analysis. The type of this research was true experiment research. The population were the tenth grade students’ of Ambulu Senior High School year 2013/2014. The samples were determined by using cluster random sampling. The design of this study was control-group post test only. The data collection method of this research used observation, documentation, interview, and test. Data analysis to study differences students’ physics achievement between which used problem-based learning model by issue discourse analysis and used direct instruction model
(conventional) was t-test (Independent Sample T-test), and to describe of students’ learning activities was descriptive statistic by using percentage analysis. The results showed that (1) There is significantly differences between of physics achievement by using problem-based learning model by issue discourse analysis and using direct instruction model (conventional), and (2) The students’ learning activities by using problem-based learning model by issue discourse analysis can be classified active
PENGARUH LUAS CELAH UDARA PADA KOMPOR BRIKET BATUBARA TERHADAP EFISIENSI WAKTU PENDIDIHAN AIR
Get PDFThe material of world oil has been scarce and it make the source of mineral andenergy department issued of the nationality energy policy, one of step is verificationenergy, that is to be increasing variety usage the alternative energy like coal, gas and newenergy. The briquette coal is alternative energy from fossil and blended with waster ortapioca flour. In usage briquette coal get in stove coal briquette the process burned usinghelp air gap at stove coal briquette. With assumption at the wide of air gap stove briquettecoal large, so the flame more than large. The purpose of this analysis is to examineinfluence of air rapid about the Efficiency Time of boiling water. The analysis steps: thecollecting material and tools that will be use for analysis. After that weighing the coal andthen briquette heating until appearance the good quality fire then set of pain which iscontain 1 liter water with air gap in stove coal briquette 16 cm2. Next when the water wasboiled, make no the time of boiling water. And then, change the water with new water andair gap to be large. The influence of air gap at stove coal briquette about Efficiency time ofboiling water is time quickly to need briquette for boiling water. The time quicker for coalbriquette in boiled 1 liter water is 10 minutes with wide gap 56 cm2 and air rapid line 0,4m/s. the conclusion is that the air gap opened wide in the process burning can be make fastprocess of burning and efficiency time of boiling water can be optimum. Because of gapwas opened. Wide air and oxygen get reaction with fire until can be make fast the rapid ofburning. More that wide gap in stove coal briquette, so oxygen more that bigger, with thehigh fire more that faster in the process boiling water. And the grade of efficiency timemore than faste

Get PDFClassroom action research conducted in class X 7 SMA Negeri 3 Lumajang academic year 2011/2012 due to the problems of learning in class X 7 the low activity of learning outcomes and completeness of physics. To overcome the problem of learning the necessary approach learning problem posing type post solution with the experimental method. Problem posing means to formulate the problem. Problem posing type post solution is approach learning problem posing type post solution or approach to learning with the filing of the same problem with the problem exemplified by the teacher. The research was conducted by 2 cycles where each cycle consists of 2 meetings. The results from the application of approach to learning problem posing type post solution with the experimental method can improve the liveliness and thoroughness of student learning outcomes. Students become active in taking into account the teacher's explanations, asking questions, answering questions, doing worksheets, group discussions, conduct experiments, and presentations. Exhaustiveness learning outcomes also increased in each cycle

Get PDFOnline learning is one form of adaptation in the field of education to face of the covid 19 pendemic. Existing technology continues to be developed for both online meeting needs and digital learning media that is suitable to support distance learning systems. One of the lesson that is considered to be lacking in utilizing digital learning media is physics. The purpose of this research was to describe student’s response to the powerpoint animation media of the heat lesson in physics. The research method used as descriptive. The respondents of this research were students of grade XI MIPA 1 SMA Negeri 1 Tanggul consisting of 32 students. This research uses data retrieval techniques through student response questionnaires consisting of aspects of operation/use of media and usage reactions. The results of the students’ response analysis to the use of powerpoint animation media amounted to 81,33% with details on each aspect was 81,41% on the aspect of media use and by 81,25% on the aspect of usage reaction. Based on the results of the research that has been done, it can be stated that the powerpoint animation media of the subject of heat received a very positive response from the respondents.  
ANALISIS HUBUNGAN INDEKS BIAS DAN INTENSITAS CAHAYA PADA BERBAGAI FLUIDA
Get PDFThis research aimed to examine the relationship between refractive index and light intensity in various fluids. This type of this research was experimental research. The measurement data obtained the refractive index values of various fluids, namely the refractive index of spirit, watered, alcohol, oil, and oil respectively 1. 3066 ± 0. 0053, 1. 319 ± 0. 0056, 1. 3422 ± 0. 0061, 1. 438 ± 0. 0054, 1. 576 ± 0. 0068. The data from the measurement of light intensity in various fluids obtained the valued of the intensity of light that passed through spirit, watered, alcohol, oil, and oil, respectively, namely 1220. 8 ± 3. 72 lux, 1219 ± 3. 9 lux, 1216. 2 ± 3, 77 lux, 1202. 6 ± 3. 88 lux, and 1180. 2 ± 4. 07 lux. The results of this research obtained a valued of r = 1 which indicates that the relationship between the refractive index and light intensity was very strong. The conclusion in this studied was that there was a relationship between refractive index and light intensity. This relationship could been seen in the refractive index, the greater the valued in the fluid would made the transmitted light intensity decrease or inversely proportional.

The diffusion equation can build form conductivity and callor equation by using technical separation variable and subtitusion can be built discreat formulation and . The distribusion of tempe-rature and callor have fourth factor hot spreadthas special in iron (Fe); thermal conductivities, kinds callor, density of mass, anomaly of material iron.This research distribusion of temperature and callor can be drawn by MATLAB program with definite element method. The result of visualization distribusion of temperature and callor with different energy level(1,3,2,3), (3,5,6,5), (5,7,9,6), (7,9,8,6), and (9,7,5,9). If the energy level is small the color of visualization become red because it’s near with hot source and the the color of visualization become greenbecause it’s far with hot source. Actually lost degradation of color in drawing of iron asresult fromdistribusiontemperature and callor in iron material.The quantities callor is brought by temperature in ironmaterial
