Abstract

Paper is one of the communication tools for administration, and is still the primary choice. In various parts of the world, paper is always used in the fields of economics, education, and so on. From the large number of paper uses, it will have an impact on the amount of paper waste that will be collected, then to meet every paper need, new paper must be produced. One solution in utilizing paper waste that can be done in the home industry is by using a pulp-making machine with unused paper or waste that has been collected to be reused in recycling paper into paper or innovative ones such as pulp bricks. The purpose of this study is to design a model of a pulp-making machine with a frame size of 1100 mm x 800 mm x 835 mm. The design of this machine frame was made to determine the load strength experienced by the frame on a pulp brick-making machine. This study uses load calculations on the frame construction design manually and with the help of the SolidWorks software. The results of the simulation using the software show a maximum von misses value of 410700N/m2 and a safety factor value of 2682.56 N/m. Thus the automatic dishwasher frame is in the safe category.

Abstract

The design of a 3-joint robogripper system manipulator hand robot for a maximum lifting capacity of 50 grams has a lifting and transport capacity for workpieces with a maximum weight of 50 grams using a servo motor mounted on a robot frame made of acrylic material and can rotate 180 ̊ with a maximum reach of 500 mm. process that still heavily relies on human labor in the manufacturing industry is lifting and transporting, particularly in the jewelry industry. This requires the operator's expertise to lift and transport the jewelry without leaving fingerprints on the surface and into the packaging.To meet the needs described above, a change in the work process is necessary. This change reduces the operator's skill requirement and can reduce human error, which can lead to product failure during quality control.Based on the shortcomings of the previous work process described, a lifting and transporting machine is needed that achieves maximum results without relying on operator skill and in shorter processing times. One machine that can be implemented to achieve the desired results is the robogripper robotic arm.The design of a 3-joint robogripper system manipulator hand robot for a maximum lifting capacity of 50 grams has a lifting and transport capacity for workpieces with a maximum weight of 50 grams using a servo motor mounted on a robot frame made of acrylic material and can rotate 180 ̊ with a maximum reach of 500 mm. and 250 mm from the center point of the robot. This hand robot aims to be a gold bar lifting tool with a maximum capacity of 50 grams so that it can reduce the number of rejects in the form of A fingerprints on the surface of goods caused by manual.

Abstract

In mining operations, the maintenance of heavy duty trucks such as the Scania P410 is essential to ensure sustained performance and operational reliability. One critical component of this unit is the centrifugal oil cleaner filter, which maintains oil purity and extends engine lifespan. However, several practical issues arise during maintenance, notably the difficulty of removing the filter housing due to slack nuts and its limited accessibility. This study presents the design and implementation of a special auxiliary tool intended to overcome these challenges and improve maintenance efficiency. The research applied the 7Ups++ innovation method, encompassing problem mapping, root-cause analysis, idea exploration, design, and implementation. The newly developed tool was fabricated using steel materials and validated through field testing at PT United Tractors, Site Muara Teweh–Tuhup. Experimental results demonstrated that the tool effectively facilitates housing removal, reduces the risk of component damage, and shortens maintenance downtime. The solution also contributes to cost reduction, enhanced technician safety, and improved work quality. Standardization and operator training were identified as key elements for broader implementation across field service operations.
