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.

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

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.

PT. Indospring, Tbk as a motor vehicle producer industry is demanded to continuously improve the quality of products made in order to remain competitive in the current era of globalization. This is in line with the amount of demand that shows an upward trend. However, the performance of one of the production equipment that is not running optimally causes the output of production is low. From this problem, how is the OEE measurement as the basis of the proposed improvement design to improve the performance of the production equipment so as to achieve World Class Value standard.In performing these performance improvements, it is used OEE method application, Fishbone Diagram, Pareto Diagram in solving the problems that occur. OEE calculation results show that the equipment in the Eye Forming Process has the lowest OEE value compared to Cutting and Process Punching that is equal to 77.94%. This is due to 2 factors namely Performance Factor (83.83%) and Quality Factor (96.18%). The result of analysis that the biggest factor of Performance (Unplanned Down Time) is the first because the process of set up is 733 minutes (52,47%) and secondly because the problem of mandril jam is 450 minutes (32,21%) and Eye Forming Defect ), The first is Eye forming Deformed 1034 pcs (60.50%) and the second is Eye forming Defect Grip as much as 381 pcs (22.29%). Based on the results of the analysis then made an improvement proposal based on the priority of critical problems that occur to improve the performance of equipment in the process.

CV. Sumber Rejeki is a home industry that makes tofu, where in its production the company has not conducted a quality analysis. 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.

UD. Arief Bersaudara merupakan home industry yang memproduksi berbagai jenis songkok di Kota Gresik. Agar dapat bersaing dengan usaha sejenis, Perusahaan perlu menjaga dan meningkatkan kualitas produknya. Dalam menjalankan aktivitas produksi, Perusahaan menemukan bahwa produk yang dibuat selama produksi mengalami cacat. Cacat tersebut disebabkan oleh beberapa faktor, baik dari faktor manusia, faktor mesin yang digunakan, faktor bahan baku yang digunakan berkualitas kurang baik, faktor lingkungan yang berpengaruh terhadap pencahayaan, dan juga karena faktor metode yang digunakan. Cacat produk yang terjadi berupa pengesuman kurang bagus, penjahitan kurang rapi, dan pemotongan kurang presisi. Tujuan dari penelitian ini adalah mengidentifikasi penyebab cacat defect serta dengan menghitung nomor prioritas risiko. Metode yang digunakan untuk menemukan dan melakukan identifikasi faktor penyebab cacat pada produksi songkok adalah mengguankan metode Ishikawa Diagram. Sedangkan usulan perbaikan yang menjadi acuan dalam penelitian ini dilakukan dengan cara melakukan perhitungan Risk Priority Number (RPN) dengan menghitung setiap nilai yang ada pada indicator yang diukur untuk mendapatkan nilai RPN tertinggi yang berarti memberikan dampak risiko paling besar. Metode yang digunakan adalah Failure Mode Effect Analysis (FMEA). Berdasarkan hasil penelitian menunjukkan tiga defect yang teridentifikasi dengan nilai Risk Priority Number tertinggi 245 pada pemotongan kurang presisi, dengan nilai RPN 175 pada Penjahitan tidak rapi, dan nilai RPN 150 Pengesuman Kurang Bagus. Rekomendasi perbaikan berdasarkan hasil analisis adalah owner harus melakukan pengawasan yang baik kepada pekerja bagian, selain itu peningkatan keahlian pekerja mutlak dilakukan untuk menjamin kualitas yang baik.
