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.

Abstract

Background: Financial inclusion in Indonesia continues to face structural barriers, particularly among informal households and micro-enterprises that remain underserved by conventional banking systems. Although financial technology has expanded access to digital finance, unsecured digital lending has also generated concerns regarding over-indebtedness and systemic vulnerability. Digital gold pawn and bullion services offer an alternative inclusion model based on real-asset collateral. Methods: This study employs an integrated mixed-method approach combining descriptive quantitative analysis of secondary data from 2018–2024 with qualitative examination of financial regulations and governance frameworks related to digital gold-based finance. Findings: The findings indicate significant growth in digital gold pawn users, transaction values, and bullion accounts, particularly among unbanked populations and micro-enterprises. Gold-backed financing demonstrates lower default risk and more stable performance than unsecured digital credit due to the stabilizing role of tangible collateral. Digital integration has expanded geographic outreach and improved transaction efficiency, although regulatory fragmentation and uneven consumer protection remain important challenges. Conclusion: Digital gold-based finance can strengthen financial inclusion without undermining systemic resilience when technological scalability is structurally aligned with real-asset discipline and harmonized oversight. Novelty/Originality of this article: The study advances a hybrid financial inclusion framework that connects informal asset ownership with formal financial systems, and empirically demonstrates how asset-backed digital intermediation reshapes risk allocation, access dynamics, and stability outcomes within a developing digital economy.

Abstract

The rapid development of IoT research in various fields has promoted the evolution of manufacturing in the Industry 4.0 context. However, the growing and dispersed literature makes it difficult to see the dominant trends and open challenges. The aim of the study is to synthesize the existing IoT research in the manufacturing, by analyzing the sectoral adoption, enabling technologies and implementation objectives. The review develops a systematic understanding of the links between manufacturing sectors, IoT technologies and operational priorities to identify dominant research directions and gaps for future research. A systematic literature review was conducted according to the PRISMA guidelines, screening and analysing peer-reviewed studies along three analytical dimensions: distribution by manufacturing sector, typologies of IoT technologies and strategic objectives of implementation. The analysis identified shared adoption patterns in some manufacturing sectors, common use of sensor-based and cloud-enabled technologies, and a high emphasis on productivity, monitoring and efficiency of operations. The results reveal a significant concentration of IoT research in discrete manufacturing, as well as noticeable attention in process manufacturing, healthcare and general manufacturing, while other sectors remain less explored, indicating an uneven research focus across industries. In terms of technology, Industrial IoT and smart manufacturing solutions are the most common, followed by IoT-enabled digital twin technologies, while the combination of IoT with artificial intelligence, machine learning, and computer vision indicates a growing shift towards more adaptive and intelligent systems. A smaller portion of IoT implementations are related to sensors and monitoring applications, blockchain enabled IoT solutions and distributed architectures, while middleware and system integration appear least often. Regarding implementation objectives, efficiency enhancement is the main driver, followed by predictive maintenance, quality control and productivity enhancement, and real-time monitoring, showing a strong orientation toward improving operational performance. In summary, the synthesis implies that the IoT research in manufacturing is mainly focused on discrete manufacturing applications, operational efficiency objectives, and intelligent automation technologies. The concentration indicates a continued research focus on production optimization, while broader contexts of industrial integration are relatively underexplored.

Abstract

This study aims to analyze and control the quality of Tank Cold Water OPP model products using the Seven Tools method and the PDCA cycle. Production defect data from June 2023 to April 2024 (15 observation periods) were analyzed using checksheets, histograms, P-control charts, scatter diagrams, Pareto diagrams, and fishbone diagrams. Results show that out of 2,143,806 total production units, 79,995 defective units were recorded, yielding an average defect rate of 3.73%. Based on the Pareto diagram, Foreign Material is the most dominant defect type at 55.51%, followed by Blackdot (30.34%) and Oily (14.15%). Fishbone diagram analysis identified four main root-cause categories: machine, environment, method, and personnel. Corrective action proposals were formulated using the 5W+1H framework, covering periodic machine maintenance, production area housekeeping, SOP updates, and structured operator training. This research is expected to serve as a reference to pursuit of zero defect production.

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.
