Abstract

Competition in many companies can be measured by the level of productivity of the company. CV. Gavra Perkasa Gresik is a manufacturing company engaged in the wood processing industry, among the products produced is turning. So far, the company has never made productivity measurements so that, if output is low, the company thinks it is not good without analyzing the causes specifically and not paying attention to the efficiency of the use of resources (inputs) that are owned. Productivity measurement to find out how the condition of the company's productivity, whether experiencing an increase or decrease, is necessary to measure productivity using the model Marvin E. Mundel. This measurement is carried out on labor input, material, energy, capital and total input. The data needed for productivity analysis is taken from 2016 as the base period and 2017 as the measurement period. The results of calculation of productivity using the mundel model not all inputs have decreased, causing the company's total productivity to be 98.18% which has a good impact on the company.                Keywords: Productivity, CV.

Abstract

PT. Indospring is a manufacturing company that produces various springs for an automotive. Among those various springs, MSM 2230 type is the most produced spring at the company. The big problem in producing the spring was related with the high waste that had impact on the low productivity. The purpose of study was to analyze the waste by using the concept of lean manufacturing particularly to identify and eliminate nonvalue added activities. The study found that there were various wastes which waiting and excessive transportation were two dominant wastes with the contribution to total of wastes at 28.96% and 18.52% respectively. The appropriate tool for further analysis on wastes was selected by using value stream mapping analysis (VALSAT), and process activity mapping (PAM) was the best tool for analyzing wastes more profoundly. The use of PAM and other tools of fishbone diagram and failure mode effect analysis (FMEA) provided important information for improvement. The implementation of improvement displayed potential increase of productivity level by reducing the processing time of the spring from 113,926.83 minutes to 75,960 minutes

Abstract

CV. Gavra Perkasa is a manufacturing industry with the finished product in the form of turning. The number of sales transactions will affect the inventory of raw materials. The problem with the company is that the company's ability to predict the amount of raw materials that must be available in the following month is not optimal due to fluctuating demand. This problem will have an impact on planning inventory inventory during the production process and recording inventory usage to optimize storage costs. This study aims to plan inventory demand in the future and to plan inventory use using the Moving average  and Exponential smoothing methods. These two methods are used because the results of the demand data plot show a stationary data pattern. The accuracy of the forecasting results was analyzed with the smallest MSE, MAD, and MAPE results. Based on the analysis results, the 5-month MA method is the most accurate with prediction results in 2017 of 57000 units with MAD, MSE, and MAPE values of 3684.21, 24345260, and 0.07.

Because quality analysis has not been carried out properly, resulting in very high product defects that occur during production. In this study, the analysis carried out aims to identify what types of damage occur, and provide suggestions for improvements using the Statistical Quality Control (SQC) method. The research data were processed using the Statistical Quality Control (SQC) method with several stages of activity, namely making examination sheets, histograms, making Pareto diagrams, making control charts, and making cause-and-effect diagrams. The results showed that there were three types of defects, namely soft texture, wrong cut, and dirt. Through the Pareto diagram, it is clear that the percentage of damage to the soft texture is 5,116 bj or 38.8%, the second defect is 4.262 bj or 32.3%, and the last or lowest defect is 3,810 bj or 28.9 cut errors. %. Based on the analysis of the cause-and-effect diagram to find the root cause of the problem, it was found that there were four factors that needed to be improved, these factors were workers, machines, raw materials, and methods. Actions that can be taken to reduce product defects are to carry out regular machine maintenance, provide adequate training to workers, improve discipline, carry out good control of soybean raw materials.

Abstract

This study aims to design a performance measurement model for Supply Chain Management (SCM) at PT Circle Pro Group, Klaten, Central Java, using the Supply Chain Operations Reference (SCOR) model and Analytical Hierarchy Process (AHP). The PT Circle Pro Group has not implemented any SCM performance measurement system, resulting in unclear performance levels and difficulties in identifying improvement priorities. The SCOR model was used to structure SCM activities into Plan, Source, Make, Deliver, and Return, whereas AHP was applied to determine the weight and priority of performance indicators. A total of 17 validated indicators were developed based on the SCOR processes and company conditions. The measurement results indicated an SCM performance score of 91.47, which was categorized as above average. However, several indicators scored below 90, particularly forecast accuracy, raw material planning, and supplier delivery punctuality. Recommendations for improvement include strengthening forecasting processes, optimizing procurement planning, and enhancing supplier performance evaluation. This study produces a structured SCM performance measurement model tailored for PT Circle Pro Group, enabling continuous evaluation and improvement. The model can be adapted by other service-based companies with similar operational characteristics.

Abstract

This study addresses the importance of raw material inventory control in maintaining production continuity and minimizing operational costs in manufacturing companies. Ineffective inventory policies may lead to overstock or stockout conditions, both of which negatively impact efficiency and cost performance. Therefore, this research aims to determine the most optimal inventory control method for phosphate raw materials at PT. XYZ by comparing the Economic Order Quantity (EOQ) and Periodic Order Quantity (POQ) methods. A quantitative approach was employed using demand forecasting data, ordering cost, holding cost, and lead time. The annual demand for phosphate raw materials was estimated at 3,875,850 kg. The results show that the company’s current policy generates a total inventory cost of Rp26,629,000 per year. The EOQ method produces an optimal order quantity of 3,742.56 kg per order with a total inventory cost of Rp42,750,797 per year. Meanwhile, the POQ method results in an optimal ordering interval of every four months, with an order quantity of 1,291,950 kg and a significantly lower total inventory cost of Rp9,385,000 per year. Both methods yield the same reorder point (ROP) of 42,476 kg. Based on the analysis, the POQ method is the most efficient inventory control approach due to its ability to minimize total inventory costs and better accommodate fluctuating demand patterns. However, its implementation should consider warehouse capacity and operational constraints.
