Abstrak: Penelitian ini bertujuan untuk: (1) menghasilkan media video pembelajaran rias karakter yang layak digunakan, mudah dipelajari mahasiswa dan dapat dipakai untuk pembelajaran individual, (2) mengetahui keefektivitasan media video pembelajaran rias karakter yang dikembangkan pada materi rias karakter. Penelitian pengembangan yang menggunakan model produk Borg dan Gall yang dipadu dengan model pengembangan pembelajaran Dick dan Carey. Hasil penelitian menunjukkan: (1) media video pembelajaran layak digunakan dalam pembelajaran rias karakter pada program studi pendidikan tata arias universitas negeri medan, (2) terdapat perbedaan yang signifikan antara hasil belajar mahasiswa yang dibelajarkan dengan menggunakan media video pembelajaran rias karakter dengan hasil belajar mahasiswa yang dibelajarkan dengan menggunakan media belajar buku teks. Hal ini ditunjukkan dengan hasil pengolahan data (thitung=3,285 )pada taraf signifikansi ɑ = 0,05 dengan dk 56 diperoleh (ttabel = 1,67 ), sehingga (thitung > ttabel), efektivitas penggunaan media video pembelajaran rias karakter = 80,46%. Hasil belajar kelompok mahasiswa yang dibelajarkan tanpa menggunakan media video pembelajaran rias karakter sebesar 71,72%. Dari data ini membuktikan bahwa penggunaan media video pembelajaran rias karakter lebih efektif dalam meningkatkan kompetensi dan pengetahuan mahasiswa pada pembelajaran rias karakter dari pada tanpa menggunakan media video pembelajaran. Kata Kunci: media video pembelajaran, rias karakte, pendidikan tata rias Abstract: This study aims to: (1) produce a suitable use of character makeup learning video media, easy for students to learn and can be used for individual learning, (2) to find out the effectiveness of media character makeup learning videos developed in character makeup material. Development research using the Borg and Gall product model combined with the learning development model of Dick and Carey. The results of the study showed: (1) learning video media is feasible to use in character makeup learning in the field state university education education program, (2) there are significant differences between student learning outcomes learned using the character makeup video learning media with student learning outcomes which was learned by using media learning textbooks. This is indicated by the results of processing data (tcount = 3.285) at the significance level ɑ = 0.05 with dk 56 obtained  (ttable = 1.67), so that (tcount> t table), effectiveness of using media character makeup learning videos = 80.46%. The learning outcomes of the group of students who were taught without using the character makeup learning video media amounted to 71.72%. From these data prove that the use of character makeup learning video media is more effective in increasing students' competence and knowledge in character makeup learning than without using learning video media. Keywords: learning video media, character makeup, makeup education

The Individual

The subject of the research is the process of making managerial decisions for innovative IT projects investing. The paper focuses on the new approach to decision making on investing innovative IT projects using expert survey in a fuzzy reasoning system. As input information, expert estimates of projects have been aggregated into six indicators having a linguistic description of the individual characteristics of the project type "high", "medium", and "low". The task of decision making investing has been formalized and the term-set of the output variable Des has been defined: to invest 50-75% of the project cost; to invest 20-50% of the project cost; to invest 10-20% of the project cost; to send the project for revision; to turn down investing project. The fuzzy product model of making investment management decisions has been developed; it adequately describes the process of investment management. The expediency of using constructed production model on a practical example is shown.

The article discusses one of the modern areas of powder metallurgy – the technology of manufacturing shaped parts by the powder injection molding (PIM). For the powder-polymer mixture (feedstock) with a wax-polypropylene binder of the solvent-thermal type of removal by isobaric volume dilatometry, the dependence of PVT state parameters was studied. For each component of the polymer binder, the dependence of pressure on the temperature of phase transition was obtained. As a result of mathematical processing and analysis of PVT data for the feedstock of the studied type, a technological window of parameters has been determined that allows injection molding of «green parts» with minimal volume shrinkage. The results of a comparative analysis of the compaction of feedstock with a polymer binder catalytic and solution-thermal type of removal are presented.
