The problem arising in the study was the lack of student learning interest in Archival subject. The focus of research relied on the factors affecting student learning interest where learning instrument and teacher interpersonal communication were the anticipated factors which have impact on student learning interest. Focusing on that, we would study three variables namely Learning Instrument (X1), Teacher Interpersonal Communication (X2), and Student Learning Interest (Y). The aim of the study was to obtain information regarding the influence of learning instrument and teacher interpersonal communication on student learning interest in SMKN 1 Bandung. Current research employed explanatory survey method, whilst data collection employed questionnaire with likert scale model. Involved respondents were 103 junior students majoring in Office Administration in SMKN 1 Bandung. Analysis technique used single and double regression analysis. Research findings revealed that learning instrument is at the uppermost category, teacher interpersonal communication is at the average category, and student learning interest at the uppermost category. Results showed that learning instrument and teacher interpersonal communication have positive and significant impact on student learning interest in Archival subject in SMKN 1 Bandung. ABSTRAKPermasalahan yang menjadi kajian dalam penelitian ini adalah belum optimalnya minat belajar siswa terhadap Mata Pelajaran Kearsipan. Fokus kajiannya pada faktor-faktor yang mempengaruhi minat belajar siswa dimana media pembelajaran dan komunikasi interpersonal guru merupakan faktor yang diduga memiliki pengaruh terhadap minat belajar siswa. Oleh karena itu, penelitian ini mengkaji tiga variabel yaitu Media Pembelajaran (X1), Komunikasi Interpersonal Guru (X2), dan Minat Belajar Siswa (Y). Tujuan penelitian ini untuk mengetahui apakah ada pengaruh dari media pembelajaran dan komunikasi interpersonal guru terhadap minat belajar siswa di SMKN 1 Bandung. Penelitian ini menggunakan metode survey eksplanatory. Teknik pengumpulan data menggunakan angket dengan model skala likert. Responden sebanyak 103 siswa Kelas X Jurusan Administrasi Perkantoran di SMKN 1 Bandung. Teknik analisis menggunakan analisis regresi sederhana dan analisis regresi ganda. Berdasarkan hasil penelitian, diperoleh informasi bahwa media pembelajaran berada pada kategori tinggi, komunikasi interpersonal guru berada pada kategori sedang, sedangkan minat belajar siswa berada pada kategori tinggi. Dari hasil uji hipotesis menunjukkan bahwa media pembelajaran dan komunikasi interpersonal guru berpengaruh positif dan signifikan terhadap minat belajar siswa pada Mata Pelajaran Kearsipan di SMKN 1 Bandung.

Sarcheshmeh Copper Complex

To investigate the factors affecting splashing in Peirce-Smith copper converters of Sarcheshmeh copper complex, South-East Iran, a laboratory scale model with dimensions one eighth of the actual converter was designed and assembled. The model was filled with water. Air was impinged onto the water. The sequence of events was subsequently recorded using high speed cameras. Factors affecting splashing such as blowing angle, volumetric flow rate of air, and the distance of the blowers from water surface were studied.Using a value of 2.65×10-11 for Morton dimensionless number, it was found that splashing may be reduced by 75% if the air speed in the tuyeres is reduced from 155 m/s to 30 m/s while the nozzle distance from the melt free surface is between 2 to 0.5 meters.
