Subjek Penelitian ini adalah siswa kelas III IPA 2 SMA Methodist I Palembang yang berjumlah 34 orang. Penelitian ini bertujuan untuk meningkatkan kemampuan siswa dalam memecahkan soal teori relativitas khusus dengan pendekatan heuristik khususnya pada soal-soal penjumlahan kecepatan relativitas Einstein. Pada penelitian ini telah berlangsung dua siklus dengan tatap muka sebanyak 7 kali. Dari analisis data hasil penelitian diperoleh tingkat kemampuan siswa dan ketuntasan belajar siswa mengalami peningkatan tajam, hal ini dapat dilihat dari analisis data Tes Siklus II sebanyak 85,3 % siswa yang memperoleh nilai diatas 61, dimana pada saat pretest ketuntasan belajar siswa 0%. Dari analisis dataangket diperoleh seluruh siswa mengalami kemudahan dalam memecahkan soal-soal penjumlahan relativistik dengan pendekatan heuristik.Kata kunci : teori relativitas khusus, pendekatan heuristik]]>

<![CDATA[AbstractNickel nanopartickel has been grown on Si (100) substrate by the sputtering method. The growth parameters were 4 x 10-1 Torr pressure, 1500C temperature, 77,3 sccm Argon gas flow and 90, 30,10, 5, 1 minutes deposition time. The as deposited nickel nanoparticles were annealed for 30 minutes and 4 hours. The Nickel nanoparticles were then characterized using Scanning Electron Microscopy (SEM) and Energy Dispersive Analysis X-Ray (EDAX). The smallest size of Nickel nanoparticles found is about 50 nm.Keywords: nanoparticle, sputtering, anneal.]]>

<![CDATA[AbstractCharacterization Ni metal nanocatalyst had been analyzed on Si (100) substrate with Sputtering Growth Methods. The sputtering conditions used were 4x10-1 torr in pressure; 1500C in temperature; 77.3 sccm in Ar gas flow; and 90,30,20 minutes in time depositions. After growth deposition, metal nanocatalysts were annealed in temperature 6000C for 30 minutes. Characterizations of Ni metal nanocatalysts were used Scanning Electron Microscopy (SEM) and Energy Dispersive Analysis X-Ray (EDAX) and we found the tendency of smallest structure with decrease of time deposition.Keywords: nanocatalyst, sputtering, anneal.]]>

<![CDATA[Research has been conducted to determine the effect of the inquiry learning model on the pictorial riddle type on the understanding of the physics concepts of eighth grade students of Palembang State Junior High School 7. Riddlel pictorial type inquiry is a learning model to develop student motivation and participation from small / large group discussions in the form of images that are used as a source of discussion so that they can find answers to a problem in question. The method used in this study is the method of Quasi Experiment, with the design of the matching only post-test control group design and cluster random sampling retrieval technique divided into two classes, namely class VIII.11 as the experimental class which received learning treatment using the pictorial type inquiry learning model riddle, and class VIII.9 students as control classes who were treated using inquiry learning models. The collection technique uses tests. The analysis technique used in this study is the t-test of the right side. The results of the calculation of data analysis obtained the average value of the experimental class 81 and the mean of the control class 75.16, with a significant level of α = 0.05 obtained ttable ie 1.67 based on the calculation results there is a significant influence of the pictorial riddle type learning model towards understanding the physics concept of eighth grade students of Palembang State Junior High School 7.]]>

<![CDATA[The purpose of this study was to find out whether or not there was a significant effect of the demonstration method by using teaching aids on the physics learning outcomes of Newton's second law material in class X at Pangkalan Lampam 1 State High School. The variables of the study are veriabel bound, namely student learning outcomes and the variables of the practice, the demonstration method using props. The population in this study were all students of class X Science at SMA Negeri 1 Pangkalan Lampam which amounted to 115 students. The sample in this study was taken by purposive sampling technique with the number of samples of 80 students divided into two classes namely class X IPA 1 as the experimental class who received learning treatment using demonstration method with the number of 40 students and students of class X IPA 2 as the control class treated a conventional approach with a total of 40 students. Techniques of collecting data using tests and documentation. The analytical technique used in this study is the right-t test. The result of calculation of data analysis obtained the average value of experiments 81,00 and the average value of control class 73,75, with significant level α = 0,05 in ttable that is equal to 1,68 and titung that is 2,71. Based on the results of data calculations, it can be concluded that there is a significant influence of demonstration methods by using props to the results of physics study material law II Newton in class X in SMA Negeri 1 Pangkalan Lampam]]>
