Abstract

Planning and controlling the raw material inventory is carried out in such a way as to meet the needs of raw materials appropriately and at low cost. The problem with plate raw materials is that there is no appropriate method of controlling raw material supplies. Control of raw materials at this company is sometimes erratic due to unstable market demand. Experiencing an accumulation of raw materials when product demand decreases and there is a shortage of raw materials when product demand increases. This study aims to determine a probabilistic inventory model that is good for determining the order quantity, ordering time and safety stock by considering the minimum total cost. Based on the analysis and calculation results, the total inventory cost according to company policy is Rp. 14,734,832 / year, the total cost of the Q model is Rp. 16,300,517 / year with q value of 1,484, r is 965, ss 104, α of 0.013 and S of 2.449 and the total cost of inventory in the P model is Rp.6,384,473 / year with a T value of 0.019, R of 2.264, ss of 105 and α of 0.013. The results show that the Periodic Review System inventory model has an optimal total cost of inventory. Keywords: Inventory Control; Continuous Review System; Periodic Review System; Probabilistic.

Abstract

The number of frequencies of damage to aluminum machines at PT. XYZ in one year by 39 times. This frequency is large enough that it is necessary to carry out effective maintenance activities to reduce the amount of damage. Reliability Centered Maintenance is one of the methods used to determine how to maintain machine components that fail according to the criticality level of a component. The results of the analysis of the Reliability Centered Maintenance method at the FMEA stage found 1 component that has a high critical level with the highest RPN value of 144, namely the loader component. The selection of actions to be carried out by conditional directed or scheduled on-condition tasks is because these components will function properly if component replacement or repair is carried out. The minimum maintenance cost for loader components obtained from the calculation is Rp. 11,961,496,-

Abstract

Ali's cake (ledram) is one of Karawang's specialty foods which is shaped like a donut made from a mixture of rice flour, coconut milk, and brown sugar. The steps for making Ali cake (ledram) start from preparing the ingredients, cooking coconut milk, brown sugar, and granulated sugar. Next is the process of mixing rice flour into the coconut milk and sugar mixture, then proceed with the cake molding process and the frying process. The last stage of making Ali cake (ledram) is the packaging and shipping process. From the results of observations in the field, then an analysis was carried out for making conceptual models and simulations. The simulation of the Ali cake production process (ledram) was carried out using ProModel software. The simulation results show a high rate of cake delivery failure. Next, a repair scenario is made for the system that is already running, namely by adding man power. The simulation results of the improvement system show that there is no delivery failure in the cake delivery process flow. The transfer process of ready-to-pack cakes to ready-to-deliver cakes is smooth, there is no buildup or over capacity.

Abstract

 Production planning and control is a theory which discusses all the activities that take place in a production process which includes product planning, costs, production processes, scheduling, forecasting demand and many other products. Planning the amount of inventory that will be owned company is one of the problems often faced by companies. Especially when the inventory is one important factor that can support the company's production processes and help meet customer demand. For companies that have strategies make to stock, inventory can have a major impact on the pricing of the product or the company's finances. Appropriate inventory management can be one of the keys to minimize and optimize the company's costs to be incurred. Determination lot size in MRP is a complex and difficult problem. Lot size is defined as a quantity stated in the order acceptance and delivery of orders in the MRP. Decisions about the size of the lot and when production is very important because it involves the use of labor and equipment are economical. Based on observations there are 13 components which are arranged in the trolley assembly process and are divided into 4 work stations in the production process. After making a map process operations per each work station, the cycle time for 1800 seconds is obtained. Based on data analysis about inventory costs for each component, it can be seen that the calculation using the EOQ method is the method that produces the calculation results with the largest value of Rp. 111,000,500, - then for the L4L and POQ methods produce the calculation results that have the same value of Rp. 16,200,000. Then the decision taken is to choose the L4L method because with this technique can produce exactly how many raw materials needed.

Abstract

PT. ZYX is a foreign company automotive component sector for four-wheeled vehicles. In their third year of mass production, the production capacity reached 116 million pcs, resulting in the high cost of Dies purchase for Cold Heading machines. This condition worsened because things such as Dies having a low lifetime and the lead time for Dies purchasement is in the range of 20-40 days or more, which has the potential to cause machine downtime. This study aims to redesign the Dies of Cold Heading machine used today. Completion of the design uses the Pareto diagram analysis, FMEA, and DFM. The analysis result using the FMEA method shows the highest RPN value of 336 with the potential for insert carbide failure that cracks during assembly. The recommended corrective action is to make assembly support components, namely pokayoke parts, and make work instructions for replacing carbide inserts on Dies. The analysis results using the DFM method shows a change in term of cost. The cost for 1 unit of Dies purchasement was initially Rp. 10,247,113.00, but it dwindles to Rp. 4,623,914.23. Using the redesign to make case dies, lock nuts, collets, and stoppers components, resulted in cost efficiency of 54.87%.
