Abstract

Indonesia, dengan keragaman budaya dan kuliner yang dimilikinya, memiliki potensi besar untuk mengembangkan sektor pariwisata kuliner, terutama di daerah pedesaan seperti Desa Tanjung Alai yang kaya akan sumber daya makanan lokal. Proyek pengabdian masyarakat ini bertujuan untuk mendampingi pelaku usaha kuliner di Desa Tanjung Alai dalam memperoleh sertifikasi halal, serta meningkatkan potensi desa sebagai destinasi pariwisata kuliner halal. Kegiatan ini meliputi sosialisasi, pelatihan teknis, dan pendampingan langsung dalam proses sertifikasi halal. Sebanyak 20 usaha kuliner terlibat, dengan 85% di antaranya memenuhi dokumen dan standar yang diperlukan. Survei sebelum dan sesudah pelatihan menunjukkan peningkatan pemahaman peserta terhadap standar sertifikasi halal sebesar 70%, dan 100% terbit sertifikasi halal. Hasil pendampingan ini menunjukkan bahwa sertifikasi halal berperan penting dalam meningkatkan kualitas produk, memperluas akses pasar, dan meningkatkan daya tarik usaha kuliner bagi wisatawan Muslim. Inisiatif ini diharapkan dapat menjadikan Desa Tanjung Alai sebagai destinasi pariwisata kuliner halal terkemuka, mendorong pertumbuhan ekonomi lokal, dan membuka akses pasar global.

Abstract

This study investigates the effect of nitrogen gas-assisted static cooling on weld distortion and mechanical properties of AA5083 aluminum alloy joined by Tungsten Inert Gas (TIG) welding. Although various cooling techniques have been reported to control heat input and distortion in aluminum welding, the combined influence of static nitrogen cooling and welding current on both distortion behavior and local mechanical properties of AA5083 remains insufficiently understood. Three welding current levels (100 A, 110 A, and 120 A) were applied while maintaining constant welding speed, arc voltage, and shielding gas flow. Mechanical properties, including tensile strength and Vickers hardness, were evaluated across the weld metal, Heat-Affected Zone (HAZ), and base metal. Thermal-induced distortion was analyzed using 3D profiling and validated through Analysis of Variance (ANOVA) statistical tests. The results indicate that a welding current of 100 A with static nitrogen cooling minimizes distortion and achieves the highest tensile strength (197.41 MPa). The highest yield strength was recorded at 120 A (160.31 MPa), while the maximum hardness values were observed in the weld metal at 110 A (135.83 VHN), HAZ at 120 A (117.63 VHN), and base metal at 100 A (124.1 VHN). Statistical analysis confirms that welding current significantly influences both distortion and mechanical outcomes (p 0.05), while the cooling method shows a moderate effect. These findings demonstrate that nitrogen-assisted static cooling offers a practical approach to improving weld quality by balancing dimensional stability and mechanical performance in precision aluminum welding applications.

Abstract

The industrial revolution 4.0 has encouraged the development of automation systems, including the 6 DOF robotic arm to enhance industrial production efficiency and effectiveness. This study aims to redesign a 6 DOF robotic arm based on benchmarking with Fanuc M-20iA and ABB IRB 2600 models using AutoDesk Inventor 2024. The method employed is benchmarking by comparing designs and specifications, followed by redesigning the Bill of Materials (BoM), Operation Process Chart (OPC), and assembly chart. The results show modifications such as redesigning the base into a square shape, adding rubber strips to the gripper, creating a separate panel for the motor driver and controller, and replacing the electromagnetic gripper with a mechanical one. The final design produces a simpler robotic arm with a production cost (HPP) of Rp105,554,924.00, which is more economical compared to similar products. The newly designed gripper is recommended for vertical object handling and positioning. Thus, the design successfully reduces maintenance costs, enhances precision, and maintains optimal performance for industrial applications.
