Occasionally, electricity serves as the primary source in our daily lives. Virtually all human activities rely on electricity. Cables are necessary to transmit electricity from one location to another. One of the stages in cable production is the sheeting process, which often results in visual defects. Stickiness in the cables is a common visual defect. Therefore, a machine is required to minimize these cable defects. The motor is a crucial component of such machines and is widely used in industrial processes involving rotating rotors or similar tasks. There are various types of motors available, including DC and AC motors. AC motors are commonly used for continuous spinning over long periods, while DC motors are preferred for maintaining a consistent and controlled speed. Based on our calculations, the motor current for motor 1 is 0.391 amperes, and for motor 2, it is 0.26 amperes. Additionally, the calculated motor torque is 1750 Nm.

Muhammad Rafi Aimar Falah — 2024-05-31

The Plant Passenger Car Radial (PCR) produces radial tires and has a Non-Reinforcing Materials Department with various divisions, including the Ply Bias cutting division. One common issue in the bias cutting process is folded ply scraps, mainly found at the end of the treatment roll. Analysis revealed that the problem resulted from the start-stop operation of the let-off motor, causing the treatment roll to twist and the plies to fold. To address this issue, modifications were made to the let-off motor. An inverter was added to adjust the motor speed according to the ply width, and the PLC program was modified to synchronize the motor speed with the HMI recipe. Through five successful trials, the motor speed was effectively adjusted for different ply sizes, reducing the residual rotation of the treatment roll. Data collected showed that prior to the modification, DBC-3 had 205 kg of folded ply scraps in March 2023. After the modification in May 2023, the folded ply scrap decreased to 138 kg, a reduction of 32.7% compared to March.

Rancang Bangun Sistem Kontrol Elektro Pneumatik Pada Alat Penumbuk Hitanol

Ahmad Yusuf Ardiansyah — 2024-05-31

Hitanol is a granular chemical that is used as a raw material to make compound bladders. The manufacturing process of compound bladder starts by weighing the chemicals. Before the weighing process, hitanol undergoes an agglomeration or accumulation of particles that causes hitanol to agglomerate and makes it difficult for the operator to weigh. As a result, operator has to do the crushing process so that the hitanol returns to granular form. The crushing process is currently being done manually by hitting the hitanol using iron stick. These problems were a driving force in the design of the hitanol crusher with an electro pneumatic system. The results of the design of the hitanol crusher using a double acting cylinder with a stroke length of 250 mm controlled by electric signal. The air flow in the pneumatik cylinder is controlled by a 5/2 single coil solenoid valve that triggered by timer and relay.

In this process where several components such as tread, bead, ply, and IB are combined. Thus, the output of this assembly process is a green tire. The assembly here uses a BTU (bladder turn up) type machine, more precisely on the IMC.05.MC.02 engine. On this machine there are several problems that cause production to be disrupted due to this problem. The cause of this problem is that the components used have decreased in performance because they have been installed for years (obsolete) and also the components have been produced again so modifications are made. After being modified where to increase the type of servo drive which originally used the MR-J2S to use the servo drive with the MR-J4 type. After this modification was made on the IMC 05 MC 05 engine where previous problems such as engine errors etc. had disappeared or there were no the same problems so the machine can produce smoothly without any error.
