Abstract

The development of cellular technology continues to increase, so that currently there will be fifth generation (5G) technology. Therefore, the need for telecommunications towers and competition among contractors will increase. The optimization of the colocation project at PT. XYZ has been carried out using the case of the Mekarsari Banjar site, West Java Province using the CPM-PERT method with the POM-QM for Windows application. PERT and CPM methods are methods used to manage project completion time more efficiently and effectively. The result of the research shows that the real project processing time at PT. XYZ on this site for 19 days with a normal fee of Rp. 32,811,000,-. In accelerated conditions, the colocation project can be carried out for 10 days with a Z value = 3.77 with a probability of 99.992% with a total cost of Rp. 34,181,000,- with project effectiveness is around 47.36%.

Abstract

The screwing process is one of the important stages in the assembly of industrial products that requires high precision and time efficiency. This study implements Finite State Automata using Nondeterministic Finite Automata with the Mealy Machine model. The implementation of Finite State Automata on a 6-axis robot in the screwing process allows for better control, because each step in the process can be analyzed and programmed clearly. The system is controlled by a programmable logic controller that integrates a 6-axis robot, human machine interface, screwdriver, sensors, and pneumatic actuators. The screwing process is carried out using an automatic screwdriver, with the robot's movement following a logical sequence based on the Mealy Machine model state diagram. Each state represents the robot's operational steps, from taking tools, screws, to the screwing process. The study focuses on designing a system to move the robot according to the state diagram that activates the output based on the state transition to the input. The results show that the implementation of Finite State Automata is able to complete the screwing process consistently and repeatedly. This system also considers safe points to avoid collisions, thus supporting safety in the screwing process. The application of Finite State Automata on 6-axis robots is expected to provide convenience for users in understanding robot control in the screwing process and can be implemented according to industrial needs.
