Abstract

Solders are essential for the construction of many engineering materials. The use of soldering in electronic packaging has become increasingly critical in today's world. In the electronic manufacturing industry, alternative soldering materials based on tin metal have developed gradually over the last two decades. Manufacturing companies are primarily concerned about removing lead from electronic manufacturing and waste recycling by switching to the lead-free solder. Environmental and human health are adversely affected by exposure to high lead levels in consumer products. The manufacturing industry has switched to lead-free soldering to support their social responsibility initiatives. The three categories of lead-free solder are classified according to temperature range: high-temperature solder, medium-temperature solder, and low-temperature solder. This research is conducted based on the approach of study literature, which is obtained from some papers that generally explain lead-free solder. To provide additional knowledge which is expected to add new insights about the importance of lead-free usage and its behavior.

Abstract

Conducting robotics training as a community service to improve basic knowledge of Science, Technology, Engineering, and Mathematics (STEM) for students is one of the ways to improve their basic knowledge of Science, Technology, Engineering, and Mathematics (STEM) for students is one of the most important aspects of the facing the industrial era 4.0 and society 5.0. Through the Service-Learning approach, this community service by collaborating with Granada International in Batam by involving 29 students, consisting of 7 students from class X, 15 students from class XI, and the rest from class XII, class XI students, and the rest from class XII. The results of mentoring through robotics training were able to increase the average STEM skills of students by 38.15%. In addition, the activity was successfully implemented with participant satisfaction levels above 50% for the subject matter, instructor, and training equipment. Only 17% of the trainees stated that the training time was insufficient, especially for practicum.

Abstract

Telah dilakukan penelitian terkait dengan ketebalan lapisan mikrostruktur dengan menggunakan SEM (Scanning Electron Microscope) dan Image-J. Sampel diuji dengan menggunakan SEM untuk mendapatkan mikrostruktur dari sampel. Setelah mikrostruktur didapatkan maka dilakukan analisa ketebalan lapisan mikrostruktur dengan menggunakan teknik pengukuran secara langsung menggunakan SEM dan teknik pengukuran tidak langsung menggunakan aplikasi Image-J. Berdasarkan hasil penelitian yang telah dilakukan, pengukuran ketebalan lapisan dengan menggunakan SEM dan Image-J menunjukkan pola kurva yang sama untuk semua ketebalan lapisan. Persentase perbedaan pengukuran ketebalan lapisan dengan menggunakan SEM dan Image J adalah 0.7% untuk lapisan ke-1, 1,6 % untuk lapisan ke-2 dan 0.8 % untuk lapisan ke-3. Persentase perbedaan tersebut sangat kecil (<2%) sehingga aplikasi Image-J ini dapat digunakan sebagai alternatif di dalam pengukuran ketebalan lapisan mikrostruktur
