Abstract

High and continuous production processes inevitably generate large amounts of production waste. PT RPG is facing problems, especially with the warehouse used to store production waste which holds 17 types of waste. The warehouse is very small, with an area of only 16 m², so it cannot accommodate all 17 types of waste. This causes difficulties in waste placement activities, creates an irregular layout, and increases the risk of work accidents. The purpose of this study is to redesign the waste warehouse in order to reduce the risk of work accidents using the Class-Based Storage method and the 6S approach. This research is quantitative and involves steps such as frequency calculation, cumulative frequency, ABC classification, proposed 6S design, and proposed 3D layout model. The results showed that the warehouse area was expanded from 16 m² to 40 m², which improved the layout for material movement based on the Pareto 80/20 principle used in the ABC classification. In addition, there was a 46% increase in the efficiency of waste placement time, which supported more effective waste handling and retrieval, ultimately reducing the risk of workplace accidents. Thus, the Class-Based Storage and 6S methods proved effective in addressing the layout and safety issues at PT RPG's warehouse. Keywords: CBS, Layout, Warehouse, 6S

Abstract

Product planning, design, and development are essential phases in manufacturing, starting from conceptualization and system design to production, testing, and ultimately delivering superior products that meet consumer demands. For instance, in the oil palm plantation industry, efficient tools play a vital role. Harvesting significantly affects the quality of oil palm yields, with losses often occurring due to loose fruit detachment from the Fresh Fruit Bunches (FFB), which fall to the ground. These loose fruits, known as "berondolan," are just as valuable as those still attached to the FFB and contribute substantially to farmers' income. Currently, farmers must manually collect these fallen fruits from beneath each tree, which is time-consuming. To address this issue, the study introduces a harvesting tool designed through reverse engineering for gathering loose oil palm fruits. After processing and analysis, the proposed tool incorporates modifications, particularly in the roller section, where two 10 cm diameter stainless steel drain holes are added. Additionally, it features two 6.5 cm diameter iron drives, enhancing efficiency by increasing collection capacity by 1.5 kg per minute compared to conventional drain hole designs.

Abstract

Bumdes Mart is a supermarket in Bukit Intan Prosperous Village, Kunto Darussalam Regency, Rokan Hulu Regency, Riau Province. Supermarkets face great challenges in managing product inventory, with frequent shortages or excess inventory due to monthly sales fluctuations. Therefore, there is a need to categorize products and estimate future sales. This study aims to categorize the product groups sold by Bumdes Mart into groups A, B, and C. Then, Monte Carlo simulation is used to predict future product sales quantities, and the ROP method is used to determine the reorder point. ABC analysis, Monte Carlo simulation, and the reorder point (ROP) method are used to develop an effective inventory control strategy and solve the problem of Bumdes Mart in Bukit Intan Prosperous Village. The comes about appear that Course A items incorporate 8 item sorts. Through Monte Carlo recreation, we decided that the anticipated esteem of future deals information isn't much diverse from the real information of the previous year, and the full mistake of each reenactment is less than 5%. The ROP of each item is: 48 boxes, 53 pieces, 133 packs, 456 pieces, 32 boxes, 6 sacks, 32 boxes and 6 packs. Keywords: ABC analysis, Monte Carlo Simulation, ROP, Stock, Stock Control
