Abstract

The increasing demand for efficient and precise manufacturing processes in the automotive industry has led to the development of automated assembly systems, including pneumatic-based tools. This study focuses on the design, development, and evaluation of a pneumatic Bush installation tool for motorcycle engine mounting production efficiency. The tool was tested against manual methods (hammer and jack) to compare installation time, accuracy, and defect rates (NG). A quasi-experimental approach was used, involving trial and error testing, prototype validation, and comparative analysis. The results showed that the pneumatic system significantly outperformed the manual method, with an 80% improvement in efficiency—reducing installation time from 120 seconds (manual) to 45 seconds (pneumatic). Additionally, Bush misalignment was reduced from 40% (manual) to 10% (pneumatic), while installation-induced defects dropped from 35% to only 5%. The findings demonstrate that the pneumatic-assisted tool provides more consistent pressure control, improved accuracy, and reduced error rates, making it a superior alternative to manual methods. This study contributes to the advancement of automated assembly technologies in the motorcycle manufacturing industry.

Abstract

The utilization of solar energy as a renewable energy source has become a priority in supporting sustainable energy transitions in Indonesia. This study analyzes the potential for installing rooftop solar power plants (PLTS) in office buildings, universities, and hotels in Magelang City. The research method involves measuring roof areas using Google Maps imagery and simulating energy production through the Global Solar Atlas. The analysis indicates that with a 20% utilization rate of potential roof areas, the corresponding installed capacity can reach 230.720–333.560 kWp. Energy production estimates show outputs of up to 11,000 kWh/month for an 80 kWp capacity. These findings underscore Magelang City's potential to support renewable energy transitions through multi-faceted collaboration. This study provides a foundation for developing sustainable energy policies in urban areas.

Abstract

Kompresor udara merupakan alat yang sering digunakan pada industri. Kendala katup kompresor udara yang sering dihadapi yaitu kebocoran dan aus. Kebocoran yang terjadi pada katup dapat mengurangi efisiensi dan mengakibatkan kehilangan tekanan udara yang dihasilkan. Keausan pada katup kompresor terjadi akibat penggunaan dan kurangnya perawatan. Kaji air compressor merupakan kompresor udara tipe lama yang sudah tidak memproduksi suku cadang. Namun, masih ada industri yang menggunakan Kaji air compressor dikarenakan kapasitas kompresor udara sampai 7 bar. Perawatan dengan penggantian suku cadang diperlukan secara berkala. Oleh karena itu, reverse engineering katup Kaji Air Compressor perlu untuk dilaksanakan. Penelitian ini dilaksanakan di Jl. Jagalan No.8, Kel. Cebongan, Salatiga pada Lab Desain dan Manufaktur kampus Akademi Teknik Wacana Manunggal Semarang. Maksud dan tujuan penelitian ini adalah untuk membuat desain, kode-G dan pembuatan purwarupa katup kompresor. Manfaat penelitian ini yaitu katup kompresor dapat dibuat dengan kemiripan dimensi sebagai suku cadang. Proses pembuatan menggunakan mesin CNC Router dengan kemampuan maksimal 24.000 RPM dan 400Hz. Hasil penelitian yaitu material yang digunakan dengan plat besi tanpa perlakuan hardening dengan ukuran ketebalan 1 mm dan diameter 72,5 mm. Parameter pemakanan pada kecepatan spindel 5.000 RPM dengan feedrate 100 mm/menit sampai 150 mm/menit. Mata pahat yang digunakan yaitu carbide diameter 1,5 mm dan 4 mm. Waktu pengerjaan 180 menit. Toleransi dimensi dari benda kerja yang dihasilkan yaitu 0,1 s.d. 0,2 mm.
