Abstract

A forklift is a lifting tool that functions to move goods from one place to another, with a short distance and a certain height, this heavy equipment is very useful because it can move very heavy goods in a vertical or horizontal direction. Problems that are often especially related to damage to unit components at PT.XXX, which are composed of the main part, namely the forklift engine. Damage to this section can result in downtime and delay in the production process which results in machine performance being less effective and efficient. Effectiveness in the production process requires the right strategy to keep the machine in operation by determining the optimal maintenance time interval using the criticality analysis method. After calculating with the criticality analysis method, it is found that the components of the hydraulic system and transmission are critical components. Furthermore, preventive replacement measures for hydraulic system components can be taken after 6800 hours of operation. The transmission component can also be done after operating for 900 hours or during an overhaul. While the inspection action for hydraulic system components is carried out after operating for 620.76 hours, the transmission component is carried out after operating for 540.39 hours. After checking and inspection, the avaibility value of the two components is above 95%, which means that the inspection can increase availability and prevent downtime in the unit and optimize the production process.

Abstract

The large number of brick producers in the Batu Lapan Lubuk Pakam area, Deli Serdang, as well as market competition from manufacturers who use modern machines to produce bricks have made one brick producer who still uses traditional methods of manufacture compete to improve quality brick. To obtain good quality bricks, namely by looking at the compressive strength of the bricks produced, it is necessary to have an optimal raw material composition that can be produced through experimental designs. In this study, the experimental design used was the Taguchi method. The purpose of this study was to determine the factors that influence the quality of the bricks, to know the composition of the raw materials so that the optimal quality of the bricks was obtained, to know the usefulness of the Taguchi loss function to reduce production cost losses. From the identification of controlled factors, it is obtained the factors that influence the compressive strength of the bricks, namely the composition of the material, the time of stirring, the drying time and the burning time. Experiments were carried out with four different levels of factors. From the analysis, the optimal factor level combination is factor A level 1: clay composition 50%, factor B level 2: stirring time 4 hours, factor C level 1: drying time of 1 day and factor C level 2: burning time 3 days while the Taguchi loss function is sufficient to reduce production cost losses. The test results from 200 units of bricks showed a decrease in the percentage of brick defects from 6%-7,32% to 2,5%-3%.

Abstract

During the current pandemic, there are many permanent or temporary termination of employment by the company so that it has a very significant impact on the income of parents or students, where the reduced income generated makes it difficult for students to pay tuition fees every year. Therefore, in this study, a comparative analysis of the feasibility of students to be able to receive scholarship assistance will be carried out using the Moora and Topsis methods. Moora method is one of the methods in a decision support system where the way it works is by creating a normalization matrix and calculating the optimization value of each attribute, resulting in a ranking that is done by reducing the maximum and minimum values. While Topsis method is a method that produces rankings by making alternative preferences and comparing the results of the best alternatives. The variables used in the simulation of the eligibility analysis of scholarship recipients are the Grade Point Average (GPA), Parents' Income, House Type and Children's Dependents. The results of the research using the Moora method get an accuracy value of 70% , while the Topsis method gets an accuracy value of 80%. So it can be said that the Moora method produces better decisions in the selection of eligibility for scholarship recipients in the Informatics Study Program
