Abstract

The problem of plastic waste has become a serious global issue due to its negative impact on the environment. IKM K2 Recycle is a distributor of plastic waste, with an average sales volume of 50 tons per month and an average supply of raw materials of 80 tons per month. Companies often experience buildup in warehouses due to lack of effective control and planning. The purpose of this study is to optimize distribution costs and avoid buildup in warehouses with the Distribution Requirement Planning (DRP) method. Sales data carried out by forecasting is forwarded with distribution calculations by the DRP method. The calculation results with DRP were able to reduce distribution costs by Rp. 154,318,512 from the Company's previous calculation of Rp. 193,890,000. There is a decrease in distribution costs by a percentage of 20%. Thus, the company managed to optimize distribution costs and avoid the accumulation of goods in warehouses, which is a positive step to overcome the problem of plastic waste and negative environmental impacts.

Abstract

Business opportunities are increasing, determining strategic locations as a way to optimize profits. One of them, of course, is that EEC Siantar needs to expand, choose an optimal new location based on the criteria: rental price, capacity, distance to school, competitors, accessibility, distance to the pemilik's house, and population density. This study is to determine the optimal branch location of EEC with AHP. This study uses AHP to select optimal EEC Pematang Siantar course branch locations using pair comparison and priority criteria. The optimal location is selected based on the highest priority value and logistical consistency (CR < 0.1). Ease of accessibility has the highest weight (0.379), followed by buildings (0.379), closest distance to school (0.272), competitors (0.179), distance to homepemiliks (0.085), and population density (0.052). Ease of accessibility is an important factor in determining the location of a new branch. Alternative 3 has the highest final weight (0.413), ahead of Alternative 1 (0.303) and Alternative 2 (0.284). This shows that Alternative 3 has the most optimal combination of subcriteria for new branch locations. This study helps the EEC industrial course select the best new branch locations with the AHP method, increasing the market and profits.

Abstract

PT. XYZ is a company that focuses on providing construction materials such as ready mix concrete. The workforce is currently in decline due to the reduced prevalence of work behavior. The initial 1 hour produced 100m3 but the realization in the Company only produced 50m3. The purpose of this study was to measure the potential risk of musculoskeletal injury caused by non-ergonomic work postures. The methods used in this study are Cornell Musculoskeletal Discomfort Questionnaires (CMDQ), Rapid Upper Limb Assessment (RULA), Rapid Entire Body Assessment (REBA). This study found a significant relationship between the level of musculoskeletal discomfort obtained in respondents through CMDQ with ergonomic risk factors identified through RULA and REBA analysis. These can include poor body position, repetitive movements, or excessive workload. These findings could help in the development of theories regarding ergonomics and factors related to worker health and well-being.

Abstract

JNE Kopma UNY's logistics demand increases 2% per week, the manual courier allocation system is unable to keep up, predictions are accurate and real-time is needed. However, there is no exact accuracy for this case. The study was conducted to determine the accuracy of the smallest Mean Percentage Error (MPE) at JNE Kopma UNY by observing sales data for 2022 to predict demand. The data was analyzed using the Naive Approach, SMA and WMA methods, then measured using the MPE to determine the best forecasting method. The software used is Microsoft Excel 2016. The 3 Month (SMA) produces the highest sales prediction (Rp. 38,668,850) for January 2023 compared to Naive Approach (Rp. 35,086,330) and 3 Month WMA (Rp. 37,993,380). 3 Month SMA is proven to be superior with the lowest MPE (12.07%) and consistent performance. Naive Approach is inaccurate (MPE 20.26%) and 3 Month WMA performance is unstable (MPE 14.27%). This research recommends 3 Month SMA for JNE Kopma UNY to increase the accuracy of sales predictions and optimize stock. Opportunities for further research are open regarding the application of 3 Month SMA in various contexts.

Abstract

Industrial applications widely employ powder coating to shield products from corrosion. Effective anti-corrosion coatings enhance customer satisfaction, open new markets, and withstand temperature, abrasion, and chemicals. However, powder coating and liquid paint remain options to mitigate metal damage. Corrosion behavior of coated materials exposed to strong acids was investigated to understand the influence of liquid/powder coatings and HCl/H2SO4. This study evaluated the corrosion resistance of A0-BS3 metal specimens coated with powder (AC1-AS3) and liquid (BC1-BS3) coatings against HCl and H2SO4 solutions for 7 days. Corrosion rates were calculated and compared, and surface damage was analyzed. Corrosion occurred in all materials in HCl and H2SO4. H2SO4 exhibited 25 times faster corrosion, and coatings were ineffective. Powder coating outperformed liquid paint. Acid rain can damage liquid paint. Powder coating is the preferred choice. Ongoing research aims to enhance steel corrosion resistance, compare coatings, and assess long-term effects. This study contributes significantly to combating corrosion and developing more effective and environmentally friendly anti-corrosion solutions.
