Abstract

Kedai Kue ABC is a Small and Medium Enterprise (SME) that produces snacks such as cookies, bread, and sponge cakes. Its main product is white bread, which is supplied to five coffee shop outlets. Currently, the demand for white bread reaches 180 loaves per day from three outlets, but the SME can only fulfill 120 loaves, equivalent to supplying two outlets. This study aims to identify waste in the white bread production process and its root causes by applying lean manufacturing principles using the Value Stream Mapping (VSM) and Process Activity Mapping (PAM) methods. The process begins with mapping the current state, followed by analyzing the causes of waste using a fishbone diagram. Subsequently, a more efficient future state map is developed. The results identify two main types of waste: motion waste and transportation waste. The proposed improvements can reduce production time by up to 1,112 seconds (18.95 minutes). Recommendations include eliminating non-value-added activities, combining processes, increasing machine capacity, adding tool racks, rearranging the production layout, and applying the 5S principle to enhance production efficiency at Kedai Kue ABC

Abstract

The rapid development of the industrial world has increased competition among companies, especially in meeting production needs for large and timely demand. This research aims to understand the production process, predict and analyze capacity requirements, and determine the appropriate instant mortar production target for the companies. Forecasting methods are used to estimated incoming demand, and Rough Cut Capacity Planning (RCCP) is employed to determine the capacity a production facility can provide or need within a certain period. RCCP calculates the required capacity using three inputs: MPS, Production Time, and Historical Proportion. Forecasting results using the Single Exponential Smoothing method with a smoothing factor of 0.9 yield the smallest error indicators for four metrics: MAD, MSE, MFE, and MAPE. RCCP results, with a utility of 0.83 and efficiency of 0.93, indicate that the 2023 production capacity requirement is 239,066,667 minutes, while capacity availability is 184,535,560 minutes, meaning the production target cannot be met on time. To determine the appropriate production target, the company employs two strategies: increasing the production load by adjusting the MPS with a production capability of 276,803 and enhancing capacity by implementing a three-shift system, thereby boosting facility production.

Abstract

PT GMK is a company in the chocolate industry, with its main product being Collata chocolate blocks. Despite being one of the leading producers, the company faces significant challenges in maintaining product quality, especially regarding color, aroma, and weight, which do not meet specifications and could potentially reduce consumer trust. This study aims to identify the root causes of product defects and offer corrective solutions using the Failure Mode and Effect Analysis (FMEA) method and Fishbone Diagram analysis. Based on data from observations and interviews with the production and quality control teams, three main defects were identified with the highest Risk Priority Numbers (RPN): color deviation (RPN 540), aroma deviation (RPN 245), and weight deviation (RPN 120). The Fishbone analysis reveals that human, machine, environment, and method factors significantly contribute to these defects. Proposed corrective actions include retraining operators to improve process understanding, periodic calibration of weighing machines, and improving production environment conditions by adding adequate ventilation. Implementing these improvements is expected to reduce defect rates and enhance the consistency of chocolate bar quality at PT GMK. Additionally, it will strengthen the company’s competitiveness in the market by ensuring higher consumer satisfaction and loyalty

Abstract

PT. XYZ is a company engaged in the soft drink manufacturing industry. One of its products is Okky Koko Drink Lychee. The production capacity of PT. XYZ is 6,000 boxes per shift. The problem that often occurs at PT. XYZ is the discrepancy between the company's work plan and budget (RKAP), production that has been determined at the beginning of the year based on actual data releases. So that the production planning that has been carried out by PPIC is considered less valid, because it is only based on historical data estimates. Based on the results of the study that has been carried out by determining data patterns using the eviews application using the Augmented Dickey Fuller (ADF) test, a trend data pattern is obtained and the methods used are Moving Average, Exponential Smoothing and Linear Regression. Using a smoothing constant with a value of M = 2-9 on the Moving Average, ? used in Exponential Smoothing 0.1-0.9 and x = 2 on Linear Regression. The method that has the smallest level of forecasting error is the Exponential Smoothing method with a value of a = 0.8, because it has a MAD value of 29,931.92, an MSE value of 1,328,504,000 and a MAPE value of 0.27% with a forecast value for the next period of 160,269. So a = 0.8 is the best for forecasting Okky Koko Drink Lychee at PT. XYZ
