Abstract

PT.Coca-Cola Amatil Indonesia is a manufacturing company that produces beverages such as soft drinks, tea, milk, juice, isotonic and mineral water, located in Pandaan. This company has a distribution area that is spread almost all over Indonesia. In the Surabaya area, the company has 30 kiosks/salesmen as partners. The distribution of products in the Surabaya area is done through Take Order (TO) sales. The final product is distributed to consumers through third parties. The purpose of this research is to determine the distribution route with the shortest distance. The distribution problem experienced by this company is better known as the Traveling salesman problem (TSP). TSP is a combinatorial problem where when the problems faced are increasingly complex, the time needed is also getting longer. Several methods for solving TSP have been proposed. One of the best is the metaheuristic method, one of which is Ant Colony Optimization (ACO). In this research, the ACO method is used to solve the TSP problems encountered. The routes generated from the ACO method are 41.3 km which is 9.03% shorter than the actual route.

Abstract

Heavy workload and non-ergonomic facility layout design will result in the excessive labor force and wrong body position. PT. Prestasi Ide Jaya produces slippers and Eva sponges. Eva sponge is the base used in the manufacture of soles or parts of sandals. From the observations that have been made on the production floor of slippers and Eva sponges, there are still non-ergonomic production operator activities, namely in the mixing, cutting, and packing processes. The objectives to be achieved in this study are to improve the position of production operators in the company using the Rapid Entire Body Assessment (REBA) method and provide suggestions for improving work postures and facilities by the results of the posture assessment using the Rapid Entire Body Assessment (REBA) method. The results of the study stated that the insole screen printing section workers got a category five score, the plong cutting section workers got a category seven score, the flip-flops assembly section workers got a category five score, the finishing section workers got a category five score, and the packing section workers got a category five score. All scores can be interpreted as a moderate level of risk and require preventive action.

Abstract

Company resources that are less effective and efficient cause problems in the production planning of PT. X, a company engaged in manufacturing spiral pipes, often experiences time delays in the spiral pipe production process due to a large number of requests, so the fulfillment of consumer demands is hampered. To overcome these problems, this research was conducted using the Capacity Requirement Planning (CRP) method so that companies can plan and implement arrival rates to adjust orders according to the available time capacity and identify work center areas where the production process is faster. The data processing that has been carried out shows different results between the company's methods, namely getting a total lack of time capacity of 549.77 hours, while the CRP method gets a total lack of time capacity of 288.2 hours so the CRP method is considered better because of the total shortage of time capacity. produced is smaller than the company's previous method.

Abstract

Surya Galon Agent is one of the gallon agents in Sidoarjo. The gallon product that is in great demand is the AQUA gallon. The problem faced is the high number of defects. This research aims to identify the types of defects that cause high levels of weekly defects for one year, determine the factors that influence the quality of AQUA mineral water gallon products at Galon Surya Agent, analyze the main causes of each type of defect and provide suggestions for improvement using the Lean Six Sigma approach. The Lean Six Sigma method seeks to integrate Lean manufacturing principles with Six Sigma. From the total number of gallons of AQUA mineral water products totaling 5720 units, the number of damaged units was 220 units. From research that has been calculated, the DPMO result is 1282 with a sigma level of 3.73. These results show that quality control for AQUA gallon mineral water products still requires improvement to minimize the number of defects. Analysis of SQCDMPE (Safety, Quality, Cost, Delivery, Moral, Productivity, Environment) is Improved monitoring of raw materials; Reduction in defect rate from 3.73 sigma to 4.01 sigma, an increase of 0.28 sigma; Decrease in repair costs through quality control; Improvement in timely delivery of products to consumers, reducing customer complaints; Increased employee satisfaction and motivation through training programs and rewards; Increased productivity due to process improvements and more regular machine maintenance; Reduction in environmental impact through better waste management and use of more eco-friendly raw materials.

Abstract

The effectiveness of the system of public education in a country is one of the most important aspects of its development. The COVID-19 initiative affected the educational system previously. The education system in Indonesia, however, is utilizing the offline or non-network learning approach now that the COVID-19 pandemic conditions, particularly in Indonesia, have abated. The teaching and learning process that takes place in schools exposes pupils to issues that develop in the educational setting and are frequently experienced by students. The frequent occurrence of saturation and exhaustion during school activities is one example. The objective of this final project is to determine the level of saturation and fatigue in offline learning among students at ABC Elementary School and to propose improvements to minimize the levels of saturation and fatigue. The methods used for research are MBI-SS (Maslach Burnout Inventory-Student Survey) for the level of saturation and SOFI (Swedish Occupational Fatigue Inventory) for the level of fatigue. The research results from 75 students show that for the level of saturation, there are 49 students (65%) in the low category, 25 students (34%) in the moderate category, and 1 student (1%) in the high category. For the level of fatigue, there are 56 students (75%) in the moderate category, 19 students (25%) in the moderate category, and 0% in the high category. To saturation and fatigue, the school can engage in ice-breaking activities, inject humor during learning sessions, and provide additional nutrition such as pudding or similar items in the morning.

Abstract

PT. ABC is a manufacturing company specializing in the production of teak wood products, including flooring. To ensure the production of high-quality products, PT. ABC implements quality control measures, starting with the identification of product defects to minimize process errors. The goal of this research is to identify product defects at PT. ABC and determine the root causes of these defects using the Fault Tree Analysis (FTA) method. Additionally, the study aims to provide improvement suggestions for preventing and reducing potential causes of product defects. The results of this research indicate that the main defect is related to incorrect dimensional size. During product sampling within the initial 180 minutes of the production process, the probability of incorrect size is 15.69%, followed by lumps with a probability of 11.21%, and rough surface with a probability of 8.20%. Areas requiring improvement include: 1. Workforce: Skilled and disciplined personnel are needed to follow procedures and equipment specifications in the flooring production process at PT. ABC; 2. Process: Maintenance activities should be enhanced, and regular checks should be conducted as necessary.
