Abstract

Distribution is an important activity that companies need to pay attention to. Improper planning for distribution activities can potentially waste both cost and time. Determining the shortest distribution route could help companies effectively reduce distribution costs. This research was conducted on a small and medium enterprise (SME) located in Rangkasbitung, Indonesia that sells various types of bread. Distribution activities carried out by Jaya Roti were found to be still conventional, while the distribution carried out to the city of Serang has many locations and complex route combinations. This research utilized the metaheuristic method of Ant Colony Optimization (ACO) with MATLAB software to determine the shortest route, which is included in the Travel Salesman Problem (TSP). The result of the shortest route determination was a total distance of 93,484 Km with an efficiency rate of 26.97% and a resulting cost of IDR 170,795.

Abstract

X University is one of the private universities located in the East Java province. To retain prospective students and encourage them to register, informational media through promotion is necessary. To determine the best promotion strategy, student profile data is utilized. The accumulated student profile data must be processed through data mining. In this research, the K-means method is used for data mining. The K-means measurement results are divided into three groups: Cluster 1 includes P1, P7, and P8; Cluster 2 includes P2 and P9; and Cluster 3 includes P3, P4, P5, P6, and P10. The risk management process is carried out in three stages: risk identification, risk assessment, and risk mitigation. The results of the risk identification phase showed that there were 15 risk variables. The risk assessment phase revealed two very high category risks, two high category risks, four medium category risks, and seven low category risks. Following the advice of X University, risk mitigation activities were selected for the very high and high-category risk variables. The results of this research are expected to contribute to an increase in the number of students at X University in the future.

Abstract

CI is a multinational company that involves manufacturing carbon black. The carbon black is packed in a 1250 kg jumbo bag and a 25 kg paper sack. Based on reject weight data for December 2019, 4.4% of paper sacks were rejected, with some caused by suboptimal packer machine settings. The study will use the design of experiment to determine critical quality factors for carbon black grade Sterling-V, identify waste in the packaging process, determine the sigma value in the packaging process, identify factors causing product defects, evaluate the risk priority number, and provide suggestions for optimal packaging machine conditions through factorial experiments. The reject weight of Sterling-V products due to reject weight was 123 out of the total production. The study results showed a sigma level of 2.205, with the engine factor being the main cause of reject weight (RPN 900). The optimal packaging machine conditions proposed for Sterling-V grade are Bulk Fill Cut Off (22.5 kg), High Pressure Air (7 bar), and Trim Final Cut Off (25 kg), which can reduce reject weight to 23 from total production.

Abstract

Technological improvements and developments have significantly altered consumers' perceptions of product quality. The production of high-quality products is only possible through a robust manufacturing process. However, during the production process, various issues may arise, leading to the production of defective products. As a result, manufacturing companies like XYZ are now required to conduct product quality control to minimize the number of defects. The objective of this study is to control product quality by reducing defects at XYZ. To achieve this, we have employed the Six Sigma method, which involves several stages, such as define, measure, analyze, improve, and control. Our research indicates that product A is prone to defects, with density being the most common type. We have calculated the DPMO (defects per million opportunities) to be 2580.66, while the sigma value is 4.297. The process capacity that produces problems at XYZ is at an average level for US industry. Additionally, we have used the 5W + 1H approach to propose improvements during the Improve stage. However, our recommendation for enhancing the production process to reduce defects is still a work in progress and needs to be executed, assessed, and monitored to reach world-class industry standards.

Abstract

Mental stress is a condition that can be caused by uncontrolled physical demands, environment, and social situations. In lecture activities, mental stress occurs in some students, reducing their performance at the lecture level. Mental stress in students tends to be high which can be caused by factors contained in lecture activities. Therefore, this study aims to analyze the mental workload experienced by students, especially Industrial Engineering students at X University class of 2020, and identify the factors that cause students' mental workload, and provide suggestions to help students overcome their mental workload. The method in this research is the Subjective Workload Assessment Technique (SWAT) to measure mental workload using respondent assessment and using Fishbone Diagram to find out the factors that cause high mental workload in students. The questionnaire was distributed to all students of class 2020 who were taking at least 18 credits in the odd semester of 2022-2023. The results of this method state that students of class 2020 have a mental burden on class activities and practicum activities. With a percentage of the time dimension of 46.78% in class activities and 55.34% in practicum activities followed by the effort dimension of 25.77% and 20.39%, the stress dimension of 27.45% and 24.27%. Based on the highest factors causing mental burden due to teaching and learning activities in class and practicum, it was found that the class of 2020 felt difficulties when studying quiz material, taking quizzes, studying practicum material, participating in practicum activities, working on practicum reports, and communicating with practicum partners. Some suggestions are to rearrange the lecture schedule or lecture hours, each lecturer makes an academic schedule for giving each assignment and quiz during the period of one semester, students are wiser in managing their free time, students take the number of credits according to their respective capacities, and so on.
