PERANCANGAN DESAIN CHUTE PADA TRANSFER CONVEYOR ABC
type: item
description: PT CC is a coal company operating in East Kalimantan Province. To achieve production targets, the company needs to perform maintenance and repair machinery to ensure smooth production processes. The fixed plant department is located at the port, where coal is transferred from hauling to barges. Coal is moved to the barges using a conveyor, which feeds into a chute that transports coal at a capacity of 2000 tons per hour with a conveyor speed of 3.2 meters per second. This causes friction between the chute walls and the coal, leading to wear on the chute walls. This research aims to design a chute liner using ceramic alumina material for the chute walls. The researchers experimented by replacing the chute wall material from ASTM A36 with ceramic alumina. Based on the research results, the design created using SolidWorks software produced shapes and dimensions that align with the research concept. Load analysis indicated that the design has a stress value of 0.10108 N/mm², which is lower than the yield strength of ASTM A36 material. Therefore, the chute design is safe from damage due to coal loading.

type: item
description: Section A2 is a team from the Engineering Department in charge of Section building and Section Venting Plant A. In Section A2 the band service problem is the problem with the highest downtime and the ATB-I3 engine is the machine with the highest downtime due to the band service problem. The high downtime band service is caused by a problem with the lock band service system, namely the motion locking system on the band service component. Therefore, a modification was made by changing the design of the lock band service. Modifications made require components such as ACM B50 S60 pneumatic cylinders, 10 mm plates, and proximity sensors. After the modification is complete, downtime calculations are performed as well as MTTR and MTTF calculations to determine the availability of values. Based on the calculations made by the author, after the modification there was a decrease in downtime of 52.97% and an increase in availability of 1.64% compared to before the modification.

type: item
description: Natural rubber is cut using a rubber cutter machine. Cutting process the rubber is raised using the lifter then the rubber will slide inside cutting machine and will be directly cut in the machine. It was found from this process a problem when the rubber slides in, the rubber gets stuck in between machines and loaders that require the operator to push using limb. This has an effect on the operator's work process increases and there is a potential risk of slipping and falling. In this research, the design of rubber pusher with control system was carried out electro pneumatic. Analysis of the strength of welded joints and bolted joints can be said to be "safe" because the load received by the frame, which is 1,283 N, does not exceed the allowable load, which is 43,774.13 N. The diameter of the shaft can be said to be "safe" because the diameter used is 20 mm above the minimum allowable diameter of 19 mm. When cutting rubber with a rubber pusher tool with electro pneumatics can reduce rubber cutting time by 36 percent. the existing potential danger will be reduced because there is no need to precision the stuck rubber.
