AREA OPTIMALIZATION WITH SYSTEMATIC LAYOUT PLANNING AND CLASS BASED STORAGE METHODS TO INCREASE STORAGE CAPACITY (CASE STUDY AT PT. SIMATELEX FACTORY BATAM)

PT Simatelex Manufactory Batam (SMB) is engaged in Coffee Maker and Pizza Maker. In the manufacture of these products, they are divided into several buildings in the Batamindo Industrial Park area, the products produced are made based on orders from customers. The products produced by the company are mostly marketed abroad (exports). In the production of Coffee Maker which is located on Jl. Beringin Muka Kuning, Lot 003, Batamindo Industrial Park Area, Batam. Finished products are then stored in the warehouse area on the ground floor of the building (Ground) which has an area capacity of 60%, so that all finished goods cannot be stored, in addition to using an area of 60%, another cause of finished goods not being able to be stored is all mismatched placement. finished goods include Finished Goods Fresh from the production line and Finished Goods to Shipping, so that there are no finished goods to shipping sequences that are not in accordance with CO (Create Order) and there is a buildup of products in the finished goods area. Therefore, the authors are interested in conducting research by anticipating these conditions so that it is necessary to optimize the storage of the finished goods. Improvements made in the form of changes to the flow of finished goods moving, re-layout the optimal warehouse stock level using the Systematic Layout Planning method, and making verbal control monitoring in the warehouse using the Class Based Storage method. From these improvements, the results obtained are an increase in area use by 60% to 80%, and also ensure that the area capacity can meet the company's needs.


PREFACE
PT Simatelex Manufactory Batam (SMB) is a company engaged in the manufacturing industry that produces Coffe Maker and Pizza Maker products, located on Jl.Yellow Face Banyan, Lot 332 -334, Batamindo Industrial Estate, Batam.
PT Simatelex Manufactory Batam (SMB) is engaged in Coffee Maker and Pizza Maker.In the manufacture of these products, they are divided into several buildings in the Batamindo Industrial Estate, the products produced are made based on orders from customers.The products produced by the company are mostly marketed abroad (exports).
Warehouse storage is one of the things that is very important by the company for continuity in carrying out the supply of goods and laying of goods after they are finished.According to Handoko (2017: 335-336) the operational efficiency of an organization can be improved due to various important inventory functions.Inventories are physical products at various stages of the transportation process from raw materials to work in process and then finished goods.These supplies may remain in storage rooms, warehouses, factories, retail stores or are being moved around factories, in haul trucks, or on ships crossing the ocean.
In the production of Coffee Maker which is located on Jl.Yellow Face Banyan, Lot 003, Batamindo Industrial Estate, Batam.The finished products are then stored in the warehouse area downstairs of the building (Ground) which has an area capacity of 60%.The products stored in the warehouse also have the same CO (Create Order) from several finished goods.
With the use of an area of 60%, all finished goods cannot be stored, so it is necessary to optimize the storage of the finished goods.In addition to the use of 60% area, another cause of finished goods not being stored is the mismatch in the placement of finished goods, including fresh finished goods from the production line and finished goods to delivery, and also the unordered finished goods to shipments that are not in accordance with CO (Create Order), so that the product appears in the finished goods area.
Therefore, the authors are interested in conducting research on "Optimizing Areas with Systematic Layout Planning and Class Based Storage Methods to increase Storage Capacity (Case Study At PT. SIMATELEX MANUFACTORY BATAM)" to find out how the flow of the process of laying finished goods until the area capacity can be sufficient company needs.

FORMULATION OF THE PROBLEM
Based on the background of the following problems, the identification of problems in the researcher's observations are: 1.What causes the use of the Finished goods storage area which results in accumulation in the warehouse area? 2. What actions are taken to ensure that the finished goods storage area is adequate according to the company's needs?3. How to design a work flow system (work flow) as well as process flow management that can accommodate activities that can provide added value from storage?

Types of Methode
This study uses a normative juridical approach (legal research) to obtain secondary data through a literature review obtained from scientific journals related to the research to be carried out.To obtain primary data through field research (field research) in the form of direct interviews with respondents.

Data Sources
Sources of data in this study are primary data and secondary data.Primary data obtained from employees, operators, and management related to the company's profile history and market objectives for the distribution of products produced by the company.As well as the data found by the library as material for writing the final report.

Method Of Collecting Data
Secondary data collection is carried out through library research by reviewing books, journals, research results, conventions and through internet media regarding matters related to research problems.Primary data was obtained by conducting field research by interviewing the informants and respondents related to the object of this research.

Data Analysis
The analysis used is using qualitative methods, namely analyze, improve, control data related to the problem under study and choose a representative based on deductive reasoning according to the ratio so that it will arrive at a conclusion that is expected to be able to provide answers and a clear picture of the problems raised.there is.

RESEARCH PURPOSES
Based on the formulation of the problem, the objectives of the observations made include: 1. Calculating capacity and identifying problems and causes that occur in the warehouse storage area in Building lot 003 PT.Simatelex Batam factory in its present condition.2. Make observations and repairs from the cause of the inflow to the outflow of finished goods to the warehouse deviation area.3. Designing and making improvements to the work flow system and management process flow for current events by comparing future conditions with the Systematic Layout Planning method and classifying products using the Class Based Storage method.

LITERATURE REVIEW Warehouse
Warehouse is an important component in the establishment of a company where we know that every company has a Warehouse area (Warehouse) which is very supportive of the company.Warehouse (Warehouse) is needed in the process of coordinating goods, which arises because of an imbalance in the supply and demand process that encourages the emergence of inventory (Inventory).Inventory requires space as a temporary storage area referred to as a warehouse (Lambert, 2001).

Systematic Layout Planning
The systematic and organized approach to layout planning that has been carried out by Richard Muther (1973) is "Systematic Layout Planning (SLP)".This Systematic Layout Planning (SLP) step is widely applied to various kinds of problems, including production, transportation, warehousing, support, service, assembly, office activities and others.

Class Based Storage
According to Heragu (1997) the Class Based Storage method is a method based on Pareto diagram research that states that have a population with the smallest percentage of millionaires.

A. Improvements to SOP (Standard Operational Procedure)
Then the SOP (Standard Operational Procedure) was changed in the Warehouse area, by creating additional documents for the Finished Goods storage in the Warehouse area, namely the Finish Good Location Form document.

CONCLUSION
From the results of the observation
