Abstract

The process of bleach washing on denim fabrics produces a paler or lighter shabby effect. The shabby effect is produced by using an oxidizing agent. The application of sodium hypochlorite can cause a decrease in color aging of denim fabrics and high tensile strength. The pH condition also affects the occurrence of oxycellulose damage which will affect the final result. Inappropriate pH will cause a very high oxidation process and produce a less shabby effect and can cause a decrease in tensile strength. Therefore, the concentration of NaOCl and pH must be adjusted properly so that optimal results are obtained. The purpose of this study was to determine the effect of optimum concentration of sodium hypochorite (NaOCl) and pH on the physical properties of denim fabric. After the process of bleach washing process experiment was carried out, a test was carried out based on two-factor Anova statistical data and the optimum visual test fabric results were obtained at a NaOCl concentration of 2 g/L using alkaline pH (10-11). The test values were obtained as follows: color fastness to rubbing are 3-4 for dry, 2-3 for wet, tensile strength 67.4 kg in warp direction, 43.1 in weft direction, fabric stiffness in warp direction 430.48, weft direction 344.54. The factory standard for a tensile strength of 65 kg warp direction, 40 kg weft direction, color fastness to rubbing 3 for dry rubbing and 2 for wet rubbing. Keywords: bleach washing, denim, sodium hypochlorite, oxycellulose, color fastnes

Abstract

In the weaving process, the process of launching the weft yarn is an important thing to consider. One of the obstacles that often occurs in the process of launching feed using a water jet loom machine is the amount of feed stuck (weft stop). The cause of the weft stop is because the process of opening the warp mouth is not clean and the weft thread slides inappropriately or too fast so that the warp mouth is in a small condition. Variations in timing opening angle of 700, 800 and 900 determine the size of the warp mouth opening, the time the weft will slide and the time the weft will arrive. From the three variations of the timing opening angle, the number of weft stops at the timing opening angle of 800 is smaller than the timing opening angle of 700 and 900, which is namely the number of big loops 0.6 times and end loops 0.8 times per hour.

Abstract

Abstract: This research is the application of quality control tools within the scope of increasing productivity of the packaging department at PT. XYZ. This study aims to determine the factors causing the decline in productivity in the packing warehouse area. The first step of the research is to analyze the input data using a Pareto diagram. The source of problems that occur from outside the packing area are four cases, namely Canceled Delivery, Part Received Without Documents, No Stock and Quality Issue. Meanwhile, for problems that occur from internal packaging, there are two, namely the No Packaging Box and No Operator Entering. By using the Ishikawa diagram and 5 whys, the sources of problems that occur in the internal packing area are analyzed further and obtained several sources of problems that contribute greatly to the decline in productivity in the packaging area, namely the process of purchasing packaging boxes which takes quite a long time and long working hours from the packaging team. Some of the solutions for internal problems offered include changing the carton box procurement process using blanket orders, upgrading the team leader's capabilities with order and budget monitoring capabilities, proposing changes in the production flow for semi-finished goods and a proposal to create a temporary warehouse for semi-finished goods.

Abstract

Inventory of raw materials is the initial process in planning and controlling production. Because by planning and controlling raw materials, it becomes one of the processes to produce an optimal production system. In order for raw material inventory to be controlled, the MRP method is used in its completion. In the case study at CV Ajax Sport, it is known that controlling raw material inventory using MRP produces an inventory value of Rp. 139,911,944,- for 12 weeks, with the number of orders for F300 raw materials as many as 71,716 units and for G300 raw materials as many as 67,297 units. And this value shows a very large value both financially and product units, so it must be managed appropriately and accurately.

Abstract

One of the advantages of the REA model is that the relative activation energy equation obtained from the experimental data can be used for other drying conditions with the same initial material and moisture content. Through convective data, an equation of activation energy is obtained which will be used for drying the data using a microwave. The simulation carried out is to compare the model data with experimental data of a microwave with a power of 0.25 W/g and a drying air temperature of 50 0C, then a power of 0.7 W/g and a drying temperature of 70 0C. increasing with microwave, the higher the value of the heat transfer coefficient (h) the simulation results are getting closer to the experimental data for the initial period of development, even making experimental data with increasing time.

Abstract

The textile and textile product (TPT) industry is one of the mainstay commodities that drive the economy in Indonesia. Export market opportunities are very open for this commodity, but the current problem is the waste generated from this industry. PT.Vonex is a textile industry with spinning and dyeing products. Textile liquid waste produced has a very concentrated color characteristic and when the dye enters the waters it can cover the surface of the water body so as to block sunlight from entering the waters. Textile wastewater treatment with the sono-Fenton method as DCA (Decolorizing Agent) can be used as an alternative choice in overcoming these problems. In this study, an analysis of the reduction of the dye was carried out by using variations in the concentration of Fenton's reagent and the length of sonication time. The variations in the concentration of Fenton's reagent used were 1:1, 2:1, 4:1, and 6:1 while the sonication time used variations of 10, 30, 60 and 90 minutes. The test results show that the use of Fenton's reagent assisted by ultrasonic waves (sonication) in textile wastewater treatment can reduce the levels of color values, pH, COD, BOD, and TSS. The results showed that the variation of Fenton reagent concentration 1:1 with a sonication time of 30 minutes was the optimum condition with a percentage decrease in color value of 99.61%, a decrease in pH value of 68.94%, a decrease in COD value of 90.64%, a decrease in BOD levels by 97.48%, and a decrease in TSS levels by 91.28%.

Abstract

: The business line at the C59 company consists of four, namely international, retail, order, and merchandise. In the line of merchandise business, there is a problem with this business. Namely that the sales target that has been set by the company has never been achieved, while the business opportunity is still wide. As a first step, identification of the company's external and internal business data is carried out. There are five problem-solving models used for data processing, namely the SAP and ETOP systematic approaches to critically identify external and internal factors, the IFE and EFE matrices, which are Input Stages that function to evaluate external and internal evaluation factors, while for the Matching Stage, only two matrices are used, namely the IE matrix to position the SBU in a 9-cell matrix, and the SWOT matrix to formulate the company's strategy, while the QSPM, which is the Decision Stage, functions to choose the The results of the IFE and EFE matrices are (2.66; 2.55) so that the position of the SBU in the IE matrix is in cell V, which results in a hold and maintain strategy. The general strategies used are market penetration strategy and product development strategy. The SWOT matrix produces nine alternative strategy formulations. At the Decision Stage, QSPM uses an alternative strategy from the IE matrix, because it is considered that nine alternative strategies from the SWOT matrix have been reflected in the hold and maintain strategy. So, the results of QSPM data processing produce Sum TAS 6.63 for market penetration strategy and 5.15 for Sum TAS product development strategy. So the market penetration strategy was chosen as the right strategy for the C59 merchandise business line. The market penetration strategy planning program is made in the form of action plans and gantt charts, namely providing examples of merchandise products, giving discounts and competitive product prices, helping with the cost of printing campus/school bulletins by installing a logo, participating in campus events, and sponsoring school/campus activities.
