Abstract

Abstrak: Penggabungan (joining) dua material dapat dilakukan baik secara mekanik, kimia ataupun fisika. Bonding adalah salah satu bentuk joining yang di dalam prosesnya terjadi difusi molekul dari salah satu permukaan material ke permukaan material yang lain (proses fisika). Fenomena difusi ini menghasilkan apa yang disebut sebagai lapisan antar muka (interface layer). Telah dilakukan monitoring/ pengamatan secara in situ proses bonding antara logam Cu dengan SnBi menggunakan metoda ultrasonik dengan cara memancarkan gelombang ultrasonik ke arah tempat terbentuknya interface layer. Dari karakteristik gelombang pantul dari interface layer dapat dievaluasi kualitas bonding selama proses. Waktu lama proses bonding tiap sampel dipilih mulai dari 15, 30, 45 dan 60 menit. Karena eksperimen dilakukan pada suhu 1800 C perlu batangan stainless steel sebagai pandu gelombang (wave guide). Pandu gelombang in diletakkan anatara objek pengamatan dan transduser ultrasonik. Dari hasil FFT terdapat pergeseran pada puncak puncak gelombang pantul dari interface layer. Pergeseran tersebut kemudian dianalisis mengunakan metoda sub space. Sebagai hasil analisis, ketebalan lapisan interface layer dapat direpresentasikan dengan dua komponen mayor.

Abstract

The purpose of this writing is to determine the factors that influence reading interest and interest in class X MA Nurul Huda Lumajang students through the sociodrama method. This type of research is qualitative research with a descriptive approach. Class X students are the subjects. The influencing factors are internal and external factors. Internal factors include intelligence, interest and attention, motivation, perseverance, attitude, reading habits, as well as physical fitness and health. Students will not be interested in reading if they do not have the desire, health, physical fitness, intelligence and motivation. Bad libraries, outdated reading materials, some even unused, little encouragement from teachers, no encouragement from parents, parents who do not provide encouragement due to lack of funds, no parental attention to children's reading. Most parents focus more on learning outcomes, reading habits that students have not acquired since childhood. The influence of the reading environment and playmates indirectly influences students' interest in reading. The uncontrolled influence of technology. For example, the influence of misuse of smartphones or gadgets, the influence of television programs on students who forget their student responsibilities.
