This study discusses the application of the material requirements planning (MRP) method in the planning of raw materials in a furniture company. The purpose of this research is to know the planning of raw materials for furniture products in UD. AA, determine the most suitable inventory model to be applied to material inventory planning and analyze the role of the MRP system in raw material procurement planning. The forecasting method used is the quantitative method of time series analysis, determining the master production schedule, calculating lot sizing (LFL, EOQ, POQ methods). From determining the Master Production Schedule, it is found that the cabinet production plan for the next three months is 4 units per period or week, and based on the calculation of Material Requirement Planning (MRP) it can be seen what components are needed for the manufacture of cabinets, how many and when each component is required. Therefore it is obtained that the total raw material requirement for wood for the next three months is 11.34 m³.

Object Of Study

Introduction: Material Requirement Planning (MRP) is a technique or a logical procedure to translate the Master Production Schedule (MPS) of the finished goods or end item into the net requirements for some of the components needed to implement the MPS. MRP is used to determine the amount of material needs to support the Master Production Schedule and when the material needs to be scheduled.Methods: The study is conducted on 13 August 2018 until 12 September 2018 at the installation Nutrition RSIA Kendangsari Merr Surabaya. Collecting data in this study using several methods, including: observation- This stage is conducted in all parts related to the object of study, starting from the Purchase Order (PO) by a head cook up to raw material stored in the storage, discussion- author interviews and collects data to communicate and discuss with the respondents. Respondents in this study are the head of the nutrition unit and head cook of RSIA who have the authority doing the purchasing.Results: Planning of procurement of raw materials to the menu rawon in RSIA can use the Exponential Smoothing method. The discussion has compared two methods of forecasting and the results are consistent with the demand’s patterns of Simple Moving Average method, Exponential Smothing. Forecasting has the lowest error rate by using Exponential Smoothing. The second conclusion is a technique of determining the appropriate Material Requirement Planning in raw material procurement to menu rawon in RSIA is using Lot for Lot.

The purpose of this study is to determine the most appropriate forecasting to predict the demand for raw materials of laundry in 2017, determine the results of the Material Requirement Planning calculation using lot permits, and to determine the total cost-efficiency of the conventional calculation method with the Material Requirement Planning method. The research method used is quantitative research, descriptive research type, and time horizon is cross-sectional for all data collection. This study uses Exponential smoothing (QM for Windows) forecasting, as an illustration, to determine the number of raw material requirements by using the analysis method, Material Requirement Planning with lot sizing measurements used are Lot for Lot, Economic Order Quantity, and Period Order Quantity. Of the three methods, the analysis results illustrate that the Lot for Lot method produces the lowest total cost of IDR. 56,160,000, compared to the total costs incurred using the company's conventional method of IDR. 175,985,288,2, So, the Material Requirement Planning method can reduce the company's inventory costs

This research was made with the aim to make production planning and inventory control in manufacturing company of plastic glass, especially for main raw material from 14 oz plastic cup product, that is Resin-HE 2.0 and whitening using lot sizing method. Due to the fluctuating demand and the accumulation of raw materials in the warehouse, the company needs for production planning and inventory control. The lot-sizing method used in this research is Period Order Quantity (POQ), Lot For Lot (LFL) and Fixed Period Requirement (FPR) which each method have a different concept. The result by using FPR Method 3 weeks and LFL in inventory control will give the lowest inventory cost to the company that is equal to Rp. 159.400,00 for Resin-HE 2.0 and Rp. 39.600,00 for whitening.

PT. Phapros Tbk is one of the oldest and biggest pharmaceutical company in Indonesia. As raw material inventory plays a key role to compete in this type of industry, it is important for PT. Phapros, Tbk to keep it well maintained. However, the Production Planning and Inventory Control Division, whose responsibility is planning and controlling the raw material has not implemented the Material Requirement Planning (MRP) method that causes a problem regarding the overstock of captopril, the ingredient for producing captopril 25 mg tablet. There are too much raw materials ordered and ends up with higher expense. The author proposed a lotting method to develop an efficient raw material planning. Results shows that using Wagner Within Algorithm method can help the company minimizes the total expense spent by Rp 984.977.

<p><em>PT X merupakan perusahaan yang bergerak di bidang manufaktur kapur barus atau kamper. Dalam pelaksanaan perusahaannya, diketahui di PT X belum memiliki metode terstandar dalam mengatur perencanaan, pengendalian serta penjadwalan tingkat kedatangan bahan baku, perencanaan dan penjadwalan biasanya dilakukan berdasarkan pengalaman dan perkiraan kepala bagian PPC saja sehingga perusahaan saat ini masih mengalami kendala dalam pengelolaan persediaannya, dimana bahan baku seringkali mengalami penumpukan di gudang. PT X juga masih menerapkan sistem manual dalam melakukan penjadwalan produksi dan pemesanan bahan bakunya. Berdasarkan permasalahan tersebut, maka dilakukan perancangan sistem informasi untuk merencanakan dan mengendalikan persediaan bahan baku di PT. X dengan menggunakan metode MRP (Material Requirement Planning). Serangkaian kegiatan yang dilakukan dalam metode MRP adalah melakukan peramalan penjualan, membuat MPS (Master Production Schedule), membuat BOM (Bill Of Material), menghitung kebutuhan bahan baku dengan metode lot sizing. Dengan adanya program aplikasi, maka akan mempermudah dan membantu pekerjaan Marketing, PPC dan gudang serta dapat membuat proses bisnis berjalan lebih cepat dan efisien.</em></p>

<p>The object of this study is the inventory system of manufacturing companies with sock products in Tangerang, Banten. Types of socks produced are plain white socks, black socks, and small socks. This study aims to determine the description of the planning and control of raw material inventory and find out how much raw materials to be prepared as well as the total cost of production produced by applying the method of Material Requirement Planning from the production process. In its production activities, the company uses 4 main raw materials making white socks namely Polyester White yarn, Spandex, Nylon, and Rubber. In one day, production produces 3 dozen socks. The raw materials used are 1 cone yarn for 2.5 dozen. So to produce 3 dozen socks a day, it takes 1.2 cone threads. From the analysis, it is known that the booking fee is Rp.28000 per message and the storage fee is Rp.2000 per unit per year. Thus the value of economic needs or Economic Order Quantity generated is 157 units. Thus, for Polyester White yarn material (75%) requires 47.1 cones, Spandex yarn (15%) requires 9,42 cones, nylon yarn (5%) and rubber yarn (5%) equally require 3.14 cone. Set up fee Rp.156586 while the storage fee Rp.157000 so the total cost Rp.313586.</p><p>Keywords: Socks, Material Requirement Planning, Economic Quantity</p>

Inventory management without Material Requirement systems in CV. Bangun Cipta Artha resulted in the lot size for each order of raw materials not optimal. One concept that can be used to plan and control raw materials is the Material Requirement Planning. This study is to determine the number of sizes of raw material orders, the exact order time, the method that produces the lowest cost for each raw material, and the effect of using MRP on inventory costs. This research conducted on 160x200cm spring bed products. Data was analyzed by making production master schedules, determining net requirements, determining lot size, and making MRP tables. Based on the results, the determination the best lot sizing is the order quantiy period which results in a total inventory cost of Rp. 26,475,220 where the total cost is lower, compared to lot for lot method which Rp. 43,464,000. part period balancing Rp. 33,106,576, and conventional method Rp.49,472,912.
