Abstract

Pelayaran Tonasa Lines is a company that distributes cement produced by PT. Semen Tonasa to various cities across Indonesia by ship. However, the company often faces challenges in its ship operations due to delays in supplying parts needed for ship maintenance, which disrupts the distribution process. This issue arises from an unorganized spare parts warehouse management system, with parts stored using a randomized storage method, where placement is irregular and not fixed. Consequently, spare parts retrieval takes longer, especially when warehouse staff changes. To address this problem, a study was conducted to redesign the warehouse layout and storage system using the dedicated storage method, assigning each spare part a fixed storage location. The study results indicate a significant improvement in efficiency, with a reduction in round-trip travel distance by 340 meters from an initial 988 meters (a 65.6% decrease), a reduction in occupied floor area by 9.5 square meters from an initial 39.5 square meters (a 75.9% decrease), and an average rack travel distance reduction of 17.9 meters from 44.9 meters (a 60.1% decrease). These findings demonstrate that the implementation of dedicated storage provides substantial improvements in spare parts warehouse management at PT. Pelayaran Tonasa Lines.

Abstract

The minimum distance of the new facility from the residential area is as far as 2 kilometers. Regulations are made to prevent pollution that can pollute residential areas. This study discusses the problem of determining the location of new facilities and determining the route of pollution vehicles by considering the minimum distance of the facility to the residential area of the compound route. The purpose of this study is to develop a mathematical model for the problem of determining the location of facilities and vehicle routes that considers the minimum distance of the facility to residential housing and compound routes. This study develops a mathematical model in the form of Mixed Integer Quadratic Programming (MIQP). The trial was conducted with 2 scenarios, namely 2 and 3 facility candidates, and from 7 to 13 customers. The trial scenario was carried out by changing the minimum distance from the facility candidate to the residential area, so that each scenario had 21 data processing times. From the results of data processing for the 2 facility candidates obtained, it can be seen that between the number of customers 7 to 13 there is no noticeable difference, and it still tends to look the same. Likewise with 3 facility candidates who do not show too big differences or even tend to be the same. The results obtained for 2 facility candidates with a minimum distance of 200 were 21,385.3, and the results for 3 facility candidates with a minimum distance of 200 were 21,237.3.

Abstract

Lecture chairs are one of the important facilities that must be owned by a university in the implementation of the teaching and learning process. Not limited to being available, but more than that, lecture chairs must also be comfortable and safe when used by students when attending lectures. Safe and comfortable chairs are needed so that students do not feel sore or experience other complaints after using lecture chairs for hours. This research aims to redesign conventional lecture chairs to be more ergonomic by using anthropometric data from PLN Institute of Technology. The data collection technique involves direct measurements of the subject's body dimensions to obtain accurate results. The method used in this study is the anthropometric method. The stages carried out start from anthropometric measurements, data adequacy and uniformity tests and make lecture chair designs. The results of the analysis show that the proposed chair design includes adjustment of the height of the backrest, height and width of the seat base, length of the writing base, as well as the length of the chair, taking into account the principle of ergonomics. From the calculation results, it was obtained that the seat design was 51cm in height, 66cm in height in the writing base, 47cm in height in the seat, 40cm in width, 55.16cm in length and 54.50cm in length. This design is expected to contribute to creating better educational facilities and improving the health and comfort of students.

Abstract

XYZ MSMEs are oyster mushroom cultivation businesses by making Baglogs (planting media) which are used as mushroom growth media. The obstacle faced by XYZ MSMEs is that the demand is not met by an average of 70% caused by the non-achievement of mushroom production against the production target of 500 kg/month, this is due to a baglog defect of 40%. This research aims to identify non-value-added activities that can affect the production process. The method used in this study is using the Lean Manufacturing approach which includes three stages, namely Value Stream Mapping (VSM), Process Activity Mapping (PAM) and Fault Tree Analysis (FTA). The results of this study showed that there was a decrease in production process time of 252 minutes or 4 hours and 2 minutes from the total time before the repair of 58,592 minutes to 58,340 minutes. In addition, 5 (five) types of waste were also obtained, including waiting time, operation, transportation, motion and defect product. Based on the waste obtained, the factors that cause waste are identified using FTAs. Based on the results of the identification, improvement proposals were given, namely placing raw materials in the same place, providing work equipment (gas and plastic baglogs), supplying equipment racks, using material handling in the form of thrusters, increasing the number of operators and implementing SOPs in each baglog production process.

Abstract

Inventory is one of the important aspects of a company's operations, especially in meeting consumer needs efficiently. However, suboptimal inventory management can lead to excess or shortage of stock that has an impact on the company's performance. This research was conducted on DANONE, a multinational company that produces food and beverages and operates in 130 countries. This study aims to measure the company's inventory management performance in the last two years using the inventory turnover, days inventory, and inventory to revenue methods. The results show that DANONE's inventory management performance is relatively low, with a decrease in inventory turnover from 6.44 in December 2021 to 3.07 in June 2022. This decline indicates a slowdown in sales and overstock as the main problem. The conclusions of this study show the need to improve inventory management in order to increase efficiency and support the achievement of company goals.
