C V. D&D JAYA is a company engaged in the Bottled Drinking Water Industry(AMDK) with the trademark "Banyu Thirta Widhi". The company produces fourproducts: 19 liter gallons, 1500 ml bottles, 600 ml bottles and 240 ml glasses. The totalproduction of 19 liter Gallons has the highest amount compared to other products,namely as much as 30%. Based on research conducted, the amount of production inFebruary to June did not meet demand. The purpose of this research is to identify thewaste that occurs and provide recommendations for improvements to reducemanufacturing lead time and increase the amount of production to meet consumerdemand. Based on the results of data processing, the manufacturing lead time (MLT)was obtained at 22786.11 seconds or 379.76 minutes and process cycle efficiency(PCE) with a value of 45.34%. The production process consists of 10330.9 seconds ofvalue added (VA) activities, 1644.7 seconds of non-value added (NVA) activities, and10810.51 seconds of necessary non value added (NNVA) activities. There are threetypes of waste: overprocessing, motion, and transportation. The proposedimprovements include reducing and merging several activities, establishing standardoperating procedures for the entire production process, adding a water quality monitorto replace the TDS Meter, adding a trolley to move gallons from the storage warehouse,and adding a conveyor roller to move gallons to the loading area. The proposedimprovements can reduce MLT from 22786.11 seconds to 21124.39 seconds. Thisimprovement reduces MLT by around 1661.72 seconds or 27.69 minutes and increasesPCE from 45.34% to 49.11%. Based on calculations after the proposed improvements,production results can meet demand. Initially the average demand per month was2995.4 gallons with an actual average production of 2723.2 gallons.
