Sandblasting is a surface cleaning process by shooting particles in the form of sand on the surface of the material, causing the material to become clean and rough. In industrial manufacturing companies where there is a structural fabrication process, of course, it will go through a sandblasting process to determine whether or not the quality of the products produced is feasible. Where to produce products with good quality, the resulting surface roughness value must be high. The sandblasting parameters used are spraying pressure, spraying time, and abrasive material size in working with A36 steel material which is one of the materials for making structural fabrication. This research uses the Taguchi method, which is one of the experimental design methods that can be used in controlling the quality of a product. With this method, the optimum parameters will be sought with the larger is better criterion. From the experimental results, it was found that the parameters that affect surface roughness are spraying pressure and abrasive material size with a percentage contribution of 66.81% and 27.60%, respectively, while the spraying time parameter did not affect surface roughness but contributed 3.30%.

The dimensional accuracy of the workpiece might be impacted by geometric variations that machines frequently experience. The geometric shape of the workpiece as a result of the machining process can be used to quantify machine quality and can take the form of cylindricality, smoothness, roundness, and other geometric shapes. The results of the workpiece surface's cylindricality will depend on machining parameters such engine rotation, feed speed, and feed depth. For the design of the research experiment and the data analysis, this study employs the Box Behnken Design in Response Surface Method that is figuring out the trial variation using 3 stages. The specimen used was ST 42 steel, and a DNMG 150404 carbide insert tool was used on a Pinacho L-1/260 conventional lathe to perform a total of 15 experimental modifications on the specimen. Furthermore, the cylindricity test was carried out using a dial indicator. The research results on the effect of parameters on surface cylindricity, namely engine speed with a Pvalue of 0.068, depth of feed with a Pvalue of 0.784, and feed speed with a Pvalue of 0.839, the three parameters were declared not to have a significant effect. The engine rotation parameter provides a contribution effect of 26.87%, the depth of feed is 0.52% and the feed speed is 0.28%.

UT Surabaya has a warehouse for storing spare parts needed either during heavy equipment maintenance work or customer demand in purchasing spare parts. This warehouse still does not maximize the existing capacity, seen from the many spare parts that are not arranged. This is due to the lack of shelf storage capacity due to the demand for many spare parts. In addition, the placement of spare parts that are not organized according to their group creates one of the problems, namely oil leaks that hit other spare parts. Seeing these problems, it is necessary to design a warehouse rack supported using the Ulrich Method by making three design concepts for selecting the most appropriate concept and in accordance with warehouse needs. Making design and structural strength analysis using Fusion 360 Software based on Finite Element Methods.

Goodway CNC turning machine GCL-2BL number T6 is one of 5 Goodway GCL-2BL CNC turning machines in the machining department of a foundry company. The machine works continuously for 24 hours in three shifts per day. In the production period from March 2022 to February 2023, the machine produced as many as 27 types of products. Machines that work continuously beyond normal limits can reduce machine capabilities, production capacity and speed up the replacement of machine spare parts due to damage that occurs to the machine. Therefore, measuring the effectiveness of the machine needs to be done to find out how the condition of the machines and equipment in the company. The method used to measure machine effectiveness is the Total Effective Equipment Performance (TEEP). In addition to TEEP, this study used FMEA and FTA methods to analyze the factors causing the low level of effectiveness of the machine. Based on the results of the data processing that has been carried out, the TEEP value is 32.43%. This value is still far below the TEEP global standard of 80%. The most influential factor that influenced the low value of TEEP was the availability rate. Based on FMEA and FTA analysis, 21 problems caused low availability rate values and 27 alternative corrective solutions were found to overcome the problems. One of the problems found was leakage of pump oil and turret hydraulic oil. This factor is caused by the long service life and quality of the seal, which is less durable, so an alternative solution to overcome the problem is to replace the seal component with a new one.

Bioring Cone Cup products are produced by Sukodono molding industry with injection molding machine. However, at the beginning of production in getting the parameter value still uses a trial and error system, so this problem results in defects that cause the weight of the product is not in accordance with the agreement so that this product must be recycled again by spending a long time. With this problem, the company suffered losses because it had to pay compensation for production delays. Therefore, more study on the effect of optimizing injection molding settings on the net response of bioring cone cup products is required. This research uses the parameters of injection pressure, injection temperature, and cooling time. To identify the impact of various elements as well as the ideal manufacturing process parameters, the Taguchi technique is employed, with the rule that the smaller the signal to noise ratio, the better. From the experimental results, the optimal combination of variables is obtained, namely the injection pressure parameter at level 1 with a value of 80 bar, injection temperature at level 3 with a value of 230? , and cooling time at level 3 with a value of 0.5 seconds

PT. Ometraco Arya Samanta which is engaged in steel manufacturing and civil engineering that produces project buildings. The company found a waste problem that occurred in the production process so that there was a delay in product delivery. In this problem, waste was found in the production process, the causes and alternative improvements that can increase the efficiency of the production process. This causes an inefficient production process, so by reducing waste it can increase production efficiency and company performance and productivity. Analysis of the Lean Manufacturing approach using the Value Stream Mapping (VSM) and Value Stream Analysis Tools (VALSAT) methods can help identify waste, analyze the causes of waste, and provide proposals in minimizing waste occurrence. The results of the calculation on process activity mapping with a result of 104.4, supply chain response matrix with a result of 55.5, production variety funnel with a result of 16.8, quality filter mapping with a result of 23, demand amplification mapping with a result of 35.1, decision point analysis with a result of 23.6, physical structure with a result of 23.4. From the results of the questionnaire distribution, the lowest results were obtained by waste environmental health and safety and waste over production and the highest results were obtained by waste motion, transportation, waste waiting. The main cause of waste is because the distance between the previous process and the next process takes a lot of time to move it, occurs because the material in the warehouse has run out and the delivery from the supplier is late, so workers are waiting for material confirmation. It is rare for sudden orders to customers in the middle of the production process that are not in accordance with the purchasing order (PO), causing the effect of delays.
