    The EOQ model is one of the oldest classic production scheduling models. The EOQ mathematical models have been established within the scope of operations management to determine the optimal inventory level. The most widely used model is the EOQ model. This journal research uses descriptive research design. A survey was conducted on automotive components of a Japanese company in Indonesia. The company is one of the fastest growing industrial company among automotive component companies. The main products are copper materials used by the automotive industry for lamps, switches, electrical panel components two-wheeled vehicles and four-wheeled vehicles. The Japanese company seeks to meet increasing customer demand but on the other hand strive to obtain optimal inventory costs, as well as demand by parent companies in Japan for faster money turnover or otherwise known as Inventory Turnover Ratio (ITR) and must be in quantity minimum or small. This means the goods in the order must be as required.

    Opis:
    Inventory management is focused with ensuring that all activities involved in labor storage and stock control are carried out efficiently and economically by those working in inventory storage. Then, there is a question for management regarding the efficiency of inventory management procedures because of inconsistencies in inventory levels that cause weaknesses such as losses incurred due to end-inventory stocks, low stock inventories, failure to meet targets and poor corporate morale. As a result, the inventory storage of the company is too busy making the job a difficult supply keeper, late in issuing materials to the department and in turn producing poor inventory service delivery. In inventory management, Economic Order Quantity (EOQ) is the number of orders that minimize total holding costs and booking costs. The EOQ model is one of the oldest classic production scheduling models. The EOQ mathematical models have been established within the scope of operations management to determine the optimal inventory level. The most widely used model is the EOQ model.

    Opis:
    The citrate gel method, similar to the polymerized complex method, was used to synthesize homogeneous tetragonal zirconia at 1000°C. Nanocrystalline tetragonal phase has been fully stabilized at wide temperature range with 10 mol.% CaO, MgO, and $Y_2O_3$ addition. Scanning electron microscopy, X-ray diffraction, and microhardness tests are used to characterize synthesized materials. The grain size and dislocation density were calculated from X-ray diffraction data. The examined material exhibits indentation size effect behavior. Results revealed that the Vickers and Knoop microhardness are dependent on indentation test load. Geometrically necessary dislocation model and modified proportional resistance model are used to analyze the load dependence of the microhardness. The highest hardness values were obtained for the samples with CaO addition; however the lowest values were acquired for sample stabilized with $Y_2O_3$ by using both Knoop and Vickers techniques. This situation might be explained using the Hall-Petch relation.

    Opis:
    The alumina-zirconia composites are one of the relatively good and promising candidates for biomaterials application, due to biocompatibility and their mechanical properties that combines high flexural strength with a high toughness. The aim of the present work is to analyze the mechanical properties of these composites, where zirconia content was varied from 5 to 50 wt%. The citrate gel method, similar to the polymerized complex method, was used to synthesize these ceramics. Scanning electron microscopy, X-ray diffraction and microhardness tests are used to characterize synthesized materials. The examined material exhibits the behaviour of indentation size effect. Modified proportional resistance model are used to analyze the load dependence of the microhardness. X-ray diffraction analysis was used to calculation of the grain size and dislocation density. It is found that hardness is decreased when the zirconia content increases with enlargement of grain size.
