Abstract

The problem that is commonly found in manufacturing companies is how to carry out the production process effectively and efficiently. Especially doing maintenance on machines to get optimal production results. The P1-29 machine is one of the machines from a metal stamping company that produces automotive parts with stamping as the main process. The P1-29 machine is often unusable for the production process due to downtime. This study aims to determine  factors that can cause downtime on the P1-29 machine in order to reduce the downtime. Therefore, an appropriate concept is needed to identify the performance of the production process with optimal effectiveness, efficiency and reducing the downtime. This appropriate concept is called by the Overall Equipment Effectiveness (OEE) method assisted by Pareto diagrams, fishbone diagrams, also kaizen five-m checklist and 5W + 1H analysis. The OEE value of the P1-29 engine for the period January-March 2022 is 62%. From this value, it can be seen that the OEE level does not meet the standards set by JIPM, which is >85%. The factors causing downtime on the P1-29 machine consist of various factors from the six big losses with the highest factor being the setup and adjustment losses of 17.47%. From the results of the fishbone diagram analysis, the factors that lead to the high value of setup and adjustment losses consist of human, material, machine, method and environmental aspects.

Abstract

In this's era, the measuring instruments used in the machining process still use a lot of mechanical principles and there are only a few that are combined with electrical components. Most of the measuring instruments that exist now are only linear and there are still few that can measure the shape of the contour. One of the tools that can be used to measure contours is CMM, but the price of this tool is very expensive. The need for tools for this contour measurement process is very much needed in the industrial world because some parts of the industry have various contour shapes and are difficult if measured without using a CMM machine. Therefore, the purpose of this study is to make a measuring instrument for contour mapping using electronic sensors. The manufacture and design of measuring instruments start with designing electricity and hardware, then continues with microcontroller programming and Matlab. This measuring instrument is then tested for linear distance measurement accuracy, accuracy per angle, and accuracy of contour shapes. The results showed that the size results had a maximum deviation of 10 millimeters with a maximum distance of 500 millimeters. The 0° angle is the worst reading angle with a deviation of 8.67 millimeters, while the 90° and 180° angles are the best reading angles with a deviation of 1 millimeter. Square and rectangular shapes can be represented quite well, while triangular shapes are less well represented due to their angles being far from perpendicular to the sensor.

Abstract

PT. XX is one of the car wheel rim companies in Indonesia whose products are sent to a number of local and international assembly companies. The main goal of this research is to forecast the demand for car wheel rim production using three forecasting methods at PT. XX. The research results are in the form of the value of demand forecasting calculation along with the error rate. It is known that there are three methods used, namely Single Moving Average, Weighted Moving Average, and Single Exponential Smoothing methods. Based on calculations from the POM-QM software, the method that is suitable to be applied in this research is the Weighted Moving Average method because the smallest error value is obtained as in the MAPE error value is 12.124%, the Mean error value is 1177.773 the MAD error value is 24587.23, the MSE error value is 1099377000, and the forecast value in the next period is 243013 units. Through this research and forecasting, the writer hoped that PT. XX could consider it a plan for the next batch of production.

Abstract

This study discusses the project completion time in the construction of a utility located in the Bogor E-Commerce Hub warehouse using the CPM and PERT methods. In addition, the critical path in the sequence of project activities will also be identified using a Network Diagram. At the end of the discussion of this study, the probability or probability of completing this project is calculated and how big is the probability or possibility if this project is accelerated or slowed down. There are 13 sequences of activities in this project with a total time of 105 days and the activities that require the longest time are finishing activities which take 29 days and the shortest activity is 1 day. From the critical path analysis using the Network Diagram, it was found that all activities in this project are critical activities that cannot be postponed and must be carried out immediately after the previous activity has been completed. In the calculation using the CPM method, the results of the project completion are 105 days, while for the PERT calculation the results are 104.5 days. The probability of this project's completion time being accelerated to 104 days is 40.90%.

Abstract

Competition strategy needs to be done to retain consumers. With case studies at outlets X fried chicken and Y fried chicken have problems in retaining consumers, so it is necessary to have a strategy for competition and analysis of opportunities for consumer movement. Data collection was carried out using a questionnaire method and literature study. To complete the case studies at X fried chicken and Y fried chicken outlets, the Game Theory method was used to select the optimal strategy to win the competition and the Markov Chain method to analyze opportunities for consumer switching. The results of processing using the game theory method of the two players namely outlets X fried chicken and Y fried chicken have the same value, therefore both players have a pure strategy, where X fried chicken uses a strategy in terms of taste and Y fried chicken uses a strategy in terms of price. With the Markov Chain method, there was a decrease in consumer movement of X fried chicken from period 0 (current period) to period 5 (5th month period) from 89.7% to 37.3% and there was an increase in consumer movement of Y fried chicken from period 0 (current period) to period 5 (5 month period) ranging from 10.3% to 62.7%.

Abstract

Digitalization is very important at this time, including in the education sector. Education has complex activities, starting from processes, education systems, curriculum, administration and other things. The success of education is greatly influenced by the speed of the interaction process which can be replaced by an information system. One of the important activities in the education sector that needs to be implemented is an information system, namely inventory of goods. This affects information on the availability of facilities and infrastructure, their condition and even their quantity. So an information system is needed to digitize the inventory of goods at the school, namely SMA Negeri 1 Babakancikao Purwakarta. This information system uses supporting tools, namely phpmyadmin, MySQL, XAMPP and Sublime Text. The result of this research is a web-based goods inventory application at SMA Negeri 1 Babakancikao Purwakarta which consists of 11 menus including: 1) login page; 2) main menu page; 3) brand page; 4) category pages; 5) item page, 6) user page; 7) incoming goods page; 8) outgoing goods page; 9) incoming goods report page; 10) outgoing goods page, and 11) stock report page. This system has made it easier for school employees/staff to record inventory and also makes it easier to monitor inventory.

Abstract

One tool that can help eliminate waste is the lean assessment matrix (LAM). LAM is used to reduce waste by calculating the weight of the relationship between waste to obtain waste priorities. Waste prioritization considers assessment of severity, occurrence, interrelationships between waste and impact value. In the previous assessment matrix, calculating the weight of waste relationship values used the Waste Relationship Matrix (WRM) method, but the drawback of this tool was that the number of questions used was too many and the value conversion did not have a standard so it did not make it easy for respondents or human experts to measure the relationship between waste. So, in this research, Waste Assessment Waste Type Weight was developed by integrating the Decision Making Trial And Evaluation. Laboratory (DEMATEL) into LAM. Implementation of the Lean Assessment Matrix modification in the case study resulted in a priority rank of waste, namely Defect waste (W3, W2, W4) and Overprocessing waste (W16 and W15). The results of the LAM tool modifications carried out can help companies determine critical waste more easily and in line with company strategy.
