Menentukan Koefisien Ekspansi Linier Batang Kuningan Dengan Teknik Espi (Electronic Speckle Pattern Interferometry)

Telah dilakukan eksperimen untuk menentukan koefisien ekspansi linier batang kuningan dengan teknik ESPI (Electronic Speckle Pattern Interferometry). Objek uji yang digunakan terbuat dari kuningan dengan diameter 45 mm, panjang 44 mm, dan dikenai beban thermal dari temperatur 30°Csampai dengan 40°C menggunakan heater (pemanas) yang ditempelkan erat dibelakang objek. Data citra spekel selama pemanasan diamati dan setiap selang waktu 1 menit disimpan di memori komputer untuk diproses. Pemrosesannya dilakukan dengan cara mensubtraksikan (mengurangkan) ke dua citraspekel pixel per pixel dan hasilnya ditampilkan di layar monitor dalam bentuk pola frinji. Dari eksperimen diperoleh harga koefisien ekspansi linier kuningan α = (1,96 ± 0,02)10-5/°C dengan standard deviasi terhadap rata-rata sebesar 1,02%.An experiment to determine the linear coefficient of expansion for the brass rod have been done by using the ESPI (Electronic Speckle Pattern Interferometry) technique. The specimen we used were brass with diameter 45 mm, length 44 mm, and thermal loaded from temperature 30°C up to 40°C use heaters behind object. The image speckle data for each 1 menit during thermal were record by the computers. Its process done by subtraction to image speckle data pixel by pixel, and the result presented on monitor screen in the fringe pattern. From experiment obtained that the average value of the linear coefficient of expansion for the brass is, α = (1,96 ± 0 ,02)10-5/°C with the deviation from average value is 1.02 %

Media Literation Model for Development of Tolerance and Multicultural Attitudes in the Students of Universitas Negeri Semarang

Indonesia is a multicultural country that consists of various races, ethnicities, customs, cultures, ethnicities, languages, and gender that are different from one another. Multicultural communities prioritize differences in equality. This condition is reinforced bytheexistenceofslogans“Bhinekatunggalika”.Becauseofthisdiversityisoursocial capital for life with respects and tolerance each other also acknowledges equality. However, the phenomenon of intolerance issues which latterly emerged in Indonesia, has created an atmosphere of injury to diversity. The problem is not only triggered by internal friction between the elements of the nation, but also is a part of the reflection of global conditions in the contemporary era as if no longer geographically isolated because of the ease of access to information through the sophistication of its technology. There is an ideological network that unites to develop participation in variouscountriesintheworld.ThisresearchwasconductedonstudentsofUniversitas Negeri Semarang (UNNES). If students can build tolerance and multicultural values, it is expected to minimize the incidence of intolerance in the future. The objectives in this study are: 1) Knowing the implementation of the media literacy movement at Universitas Negeri Semarang. 2) Develop a media literacy model and the strategy for implementingmedialiteracymodelsforthedevelopmentofmulticulturaltoleranceand values among students. Outcomes of research: 1) Making articles on scientific journal publications. 2) Arranging Textbooks. The research method uses qualitative research and is a Research and Development.     Keywords: media literacy, multicultur, tolerance, intoleranc
