Abstract

PT Karya Pak Oles Tokcer Group Bali is a pharmaceutical company that sells bokashi balm products in the Bali area. However, this product has faced several problems in the ups and downs of demand. This causes a decrease in the quality of raw materials and the large savings costs incurred by the company. Therefore, this research was carried out to forecast demand for bokashi balm products for 1 year and know the most optimal lot-sizing technique for determining the planning and controlling of raw material supplies. This research was conducted using ABC analysis, demand forecasting, and supply planning analysis using the Lot for Lot, Silver Meal, and Least Unit Cost methods. Based on the research, it was found that forecasting results for bokashi balm products measuring 15 grams and 7.5 grams using the Moving Average method for the ninth and eighth periods were the best results. Then from the results of the ABC analysis, it was found that for the 15-gram bokashi balm product, the raw materials belonged to category A, namely packaging boxes, pot lids, pots, and top and bottom labels. In contrast, for the 7.5-gram product, there were raw materials in the form of packaging boxes, lids pots, pots, top and bottom labels, and bulbs. Raw materials belonging to group A will then be calculated using the Material Requirement Planning (MRP) method. Then after calculating using 3 lot sizing methods, the Lot for Lot (LFL) method was chosen because it has the smallest total cost value, namely the 15-gram bokashi balm product of IDR 2,306,369 and the 7.5-gram bokashi balm product in the amount of IDR 4,079,780.

The results of the pareto chart analysis with the most frequent problems to get priority for repair, namely the type of plastic defect (53%). Based on the P-chart analysis the production process is still not under control or still experiencing deviations, this is shown on the P-chart that many points are beyond the control limit. Known from the results of diagram analysis fishbone related factors causing plastic defects come from human, machine, and material factors. Companies should conduct training for employees on the shrink process, conduct regular checks on production machines and replace plastic materials that are thicker than before.

Abstract

Due to passenger complaints regarding the comfort of the seats on the Trans Metro Dewata Bus, and the possibility that the design of the seats could result in musculoskeletal disorders (MSDs), it is deemed necessary to redesign the seats of the Trans Metro Dewata Bus to create an ergonomic seat design. In the process of redesigning the bus seats, the ergonomics method with an anthropometric approach was used. The ergonomic approach in question is to adjust the seat design to the anthropometric dimensions of the sample of Trans Metro Dewata Bus passengers. In this anthropometric approach, four anthropometric dimensions are determined which play an important role in chair redesign, namely (1) shoulder height, (2) knee fold (popliteal), (3) hip width, and (4) distance from knee fold (popliteal) to buttocks. For each dimension, calculations were carried out according to the procedure for 100 sample data that had been taken from passengers of the Trans Metro Dewata Corridor 3 Bus in March 2023. Based on the passenger samples that had been obtained, then the anthropometric data testing process was carried out starting from the normality test, uniformity test data, and data adequacy test.
