Simulasi Sebaran Temperatur Pelat Logam Tipis Besi dan Kuningan Berbasis Matlab
No full textSimulating the temperature distribution of iron and brass metal thin plates based on matlab has been performed. This simulation aimed to study iron plate and brass plate conductors of the temperature distributionbased on conduction mechanism on cartesian coordinate system. The initial temperature in all parts of the thin plate is room temperature, except at left side and right side of the plate is 100 oC. Through numerical calculation of heat conduction equation by Finite Difference Method, we got that the temperature at center thin plate for 10 second is 63,26oC and 62,08 oC for brass thin plate and iron thin plate, respectively
Kajian Kemampuan Berpikir Kritis Pada Konsep Fisika Dari Sudut Pandang Filsafat
No full textThe ability to think critically is one of the important skills that everyone must have, including when studying physics. Physics is the science that studies the universe and all the phenomena that occur in it. To understand physics concepts, critical thinking skills are needed to analyze and evaluate the information obtained. This research aims to examine critical thinking skills on physics concepts from a philosophical perspective. This study was carried out using the literature study method. This research has the implication that critical thinking skills need to be trained and developed from an early age, especially in studying physics. Critical thinking skills training can be done through various activities, such as discussions, presentations and problem solving

Perbandingan Kuat Medan Listrik dan Medan Magnet dari SUTT di Daerah Pemukiman, Perkebunan, dan Tanah Lapang
No full textDalam penelitian kali ini peneliti mencoba membandingkan hasil pengukuran medan magnet dan medan listrik pada ltiga medan yang berbeda-beda yaitu di daerah pemukiman, perkebunan dan tanahg lapang, hal ini peneliti lakukan untuk mengetahui kekuatan medan magnet dan medan listrik apakah masih dalam ambang batas aman. Hal ini penting dilakukan dikarenakan kita tahu bahwa dalam pembangunan jaringan kelistrikan baik SUTET (saluran udara tegangan ekstra tinggi) ataupum SUTT (saluran udara tegangan tinggi), sering sekali mendapat tentangan dari beberapa ormas seperti LSM yang menentang dan beberapa masyarakat yang tidak terima bahwa daerah pemukimannya dilalui oleh jalur SUTT maupun SUTET. Dalam pengukuran peneliti menggunaklan alat untuk mengukur medan magentik dan medan listrik yaitu Alat uji ELF Survey meter ETS-Lindgren. Dari hasil pengamatan kuat medan listrik sangat di pengaruhi oleh benda-benda di sekitarnya karena medan listrik tidak dapat menembus benda-benda isolator, medan magnet memiliki sifat dapat menembus benda-benda di sekitarnya, hal ini sesuai dan hasil pengukuran juga membuktikan bahwa kuat medan listrik dan medan magnet dari pajanan SUTT masih jauh di bawah ambang batas aman yang telah di tetapkan oleh WHO
Artistic Reflections: The Use of Photo Elicitation Method Toward Visual Artists
No full textBy this research, the author conducted the detailed and reflected of the process of photo-elicitation as a step to access respondents and to figure out theirs voices of selected word and visual. The subject of this research is a photographer from Solo, Central Java, named Pandji Vasco Da Gama. With his serial photos, titled “Republik Kresek”. The author described in detail using a photo-elicitation interview upon Pandji’s experiences with the qualitative method. First, the research conducted the identification and detailed about photo elicitations, literature study, and empirical experiences of the author for the discussion. Second, explain with related methodology about the findings during the research process. At the end of this research, the author described in a reflective way their voice related with empirical photographer’s experiences thought, and also creativity attraction as a result of the photo-elicitation interview. The conclusion of this research said that there is a potential finding during visual methodology, which is the photo is the metaphor of the meaning, photo as a representation of meaning that was attached and participant’s empowerment.
