Abstract

Manufacturing companies engaged in the system of making orders are now starting to develop with increasingly diverse needs, and the business of making agricultural and food processing machinery is no exception. UD. rekayasa Wangdi W produced the machine processing manufacturing companies engaged in the make to order system are now starting to develop rapidly along with increasingly diverse needs, and the business of making agricultural and food product processing machines is no exception. UD. Wangdi W Engineering is a Make To Order (MTO) manufacturer of processing machines which currently does not consider resource capacity and order due to date as a reference for receiving orders. Even though accepting all orders does not necessarily provide maximum benefits. To help solve these problems, a decision support system design for planning the acceptance of customer orders is carried out. The system is designed using a mathematical model that was developed and modified in linear programming. The model developed has an objective function of maximizing profits from orders received and applied in the system built. The system is designed and the Mathematical Model is processed using the branch and bound method. Based on experimentation with historical data, the results obtained are only 4 slicer and 10 spinner units with a maximum profit of Rp53,115,530.00 and order completion that does not exceed the due date. Order acceptance information is displayed in tabular form and machine scheduling information is displayed in Gantt chart format

Abstract

PT.Mesin Isuzu Indonesia manufacturing industry engaged in the automotive sector which produces machinery for Isuzu products as well as several other car parts. The warehouse is a very vital place for every company, the optimal warehouse layout will support the company's production process in meeting production targets because makes it easy to get things. The potential for tool changes can not be avoided and can occur at any time, the search process for the old tool will increase maintenance time so that it is feared that the target wil not be met. This means that the layout of the tool shed must be made optimal so that when engine maintenance occurs the search process for the tool does not take much time. ABC Classification is a method for grouping based on 3 types: fast, medium, and slow. The results of this research are the layout of tools on a shelf based on ABC classification and 5S principles

Abstract

The gallon water pump used to meet household needs, in general, is a manual pump, with an affordable price, this pump is excellent. However, the use of manual pumps is considered ineffective for water intake in gallons, so development innovation is needed for a more effective design. The purpose of this research is to design a centrifugal electric pump that is designed to facilitate the collection of water in gallons on a scale of household needs. The researcher used the Kano method to design the pump, this method was chosen so that user satisfaction is guaranteed. To get the level of product satisfaction, by distributing questionnaires to 44 respondents with 10 attributes. Analysis to determine the level of satisfaction of centrifugal electric pump products using the End-User Computing Satisfaction (EUCS) method. The level of satisfaction of centrifugal electric pump products designed with the Kano method states that most of the attributes are in an Attractive condition, meaning that the customer wants the centrifugal electric pump product to be produced immediately. With the proposed design based on human anthropometry, it is expected to be able to increase customer satisfaction.

Abstract

Capacity planning in a company's production process needs to be considered so that the products produced meet consumer demand. PT X, is a manufacturing company that focuses on tire production. One type of large-sized tire product that has the highest demand is the ABC type with a sTabel production amount per month and demand that goes up every year. In terms of fulfilling customer demand, especially requests for large tires with type ABC, PT X often has difficulty in meeting consumer demand, this happens because the capacity of the machine is not available. Therefore, the existing production capacity must be evaluated to find out whether the available capacity is sufficient with the required capacity. To analyze this problem, the Rough Cut Capacity Planning (RCCP) method, this method is to analyze and test the determination of capacity in the master production schedule. Calculation of available capacity and capacity required in a year is carried out for the process carried out, namely: Building, Spreading and venting, curing, and Trimming. For the building and trimming process, it is found that the decision of the acupacity is fulfilled, while the Spreading and venting process is required to add 1 machine, and the curing process is required to add the machine according to the number of requests per month. From these results it can be given a proposal that needs to be considered in meeting the capacity to meet consumer needs while still paying attention to production costs.

Abstract

PT. XYZ is a company engaged in wood processing. The product produced is plywood according to customer demand. After observing the production floor, several problems were found, namely that there was unused equipment in the work area. This equipment is equipment that is damaged or is not used. Besides, the cleanliness of the production floor is also poorly maintained where there is still dirt and dust. This study aims to identify problems related to waste on the production floor and design and propose the 5S method to create an effective work environment. The method used in this study uses the 5S concept approach (Seiri, Seiton, Seiso, Seiketsu, Shitsuke). 5S assessment is carried out using the audit checklist and evaluation checklist. The audit checklist and evaluation checklist are filled out by an auditor who knows clearly how the actual conditions on the production floor are. Data were collected in five work areas, namely rotary, press dryer, repair, assembling, and packing. The results of this study can be concluded that 1) problems on the production floor of PT XYZ include: there is no written procedure for elimination, there is no label on the work area, there is no regular cleaning, employees do not understand 5s, there are no procedures and 5s standards, there is no audit regarding 5s, there is no visual management system and standard procedures regarding 5s, lots of garbage scattered, dirty work surfaces and difficult to clean, everyone is not involved in 5s activities; 2) The results of the 5S assessment before improvement were 37.78% in the bad category. After planning the implementation of the improvement, the score rose to 80% in the good category
