Abstract

The development of ultrasonic sensor technology used for suitable equipment is widely carried out, such as distance sticks for the blind, floor cleaning robots, automatic garbage boxes, height measuring instruments, water volume detectors, automatic dispensers, automatic hand sanitisers, etc. In the study, the researchers developed a precision device based on an ultrasonic sensor called the COVID-19 reminder hat. The research design method is research and development, using the Borg and Gall approach. COVID-19 reminder Hat was developed using Arduino nano v3, battery, buzzer, and ultrasonic sensor HC-SR04. The product design was registered with Intellectual Property in the Industrial Design category with registration number A00202102408. The measurement distance of the ultrasonic sensor on flat objects shows an average error percentage of 2.64% from 10 cm to 300 cm with a range of 10 cm. Tests on irregular objects (humans) at an angle of zero degrees and 15 degrees showed an error at a distance of more than 200 cm and stable at a distance of 150 cm. So that 150 cm is the best distance to apply to the COVID-19 reminder hat. The development results show that the product is ready to be continued in the production and sales process.

Abstract

One of the problems that related to quality and often occurs in the sewing process at CV Batara Apparel is that there are frequent thread break problems. Termination problems that occur are caused by an error during the thread installation process that does not pass through the needle bar hole and the thread is directly passed through the needle. This results in defects in stitches such as broken stitches. In order to solve the thread break problem caused by an error during the thread installation process that does not pass through the needle bar hole, it can be overcome by implementing SOP (Standard Operational Procedure) on proper and correct machine usage procedures, briefing supervisors with the production manager so that the problems occurs when production takes place can be handled properly. In addition, the implementation of regular maintenance schedules can also solve the thread break problems that occur. Keywords: thread break, loose stitches, quality control, SOP

Abstract

The process of applying starch to the warp yarn in order to increase the weaving power of the warp yarn in the presence of a starch layer, is expected to increase the strength of the yarn and reduce the yarn hairs. One of the factors that influence the sizing process is the amount of pressure in the squeezing roll. In this process, the sizing machine uses a double size box and each size box has 2 (two) squeezing rolls. The material used is Combed Ne 40 yarn with construction ,which is the amount of tetal or the density of the yarn with the construction included in the tetal of the dense warp yarn. The method used by comparing the pressure of squeezing roll process 1 and process 2. In the first process, the squeezing roll 1 is set at 3 kN and squeezing roll 2 is 3.5 kN, while in the second sizing process, the squeezing roll 1 is set at 4 kN and squeezing roll 2 for 5kN. After the experimental process was carried out, the starch warp yarn strength was obtained which was higher, namely 351.93gr and compared to process 2 which was 345.84 gr. The higher from the strength of the starchy yarn, can make it better for weaving process.

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

The process of sewing the front body of an order for H&M Pajamas Jogger Pants has a fairly high quality, but the target for setting production targets is based on experience and estimates only. The setting of a fairly high production target of 640 pcs/day is often not achieved because the determination of the production target is not based on the level of difficulty of the work carried out by the operator (easy, medium, or difficult), the operator's skill as well as the condition of the machine used in the process. condition is good or not, so that the target set is often not achieved because it is not in accordance with the condition of the operator's ability in general. Based on the observation of the operator's working time measurement, the total standard time for the 26 manufacturing processes for the front body component of the order of H&M Pajamas Jogger Pants was 23,029 minutes. After getting the total standard time for making the front body component of the order for these H&M Pajamas Jogger Pants, a new production target can be determined, which is 542 pcs/day. This new production target is made to represent the general working conditions of operators and has taken into account the factors of slack, work fatigue and other unavoidable obstacles.

Abstract

Insert separators are part of the Open-end spinning machine that plays an important role in the process of feeding the fiber to the rotor. The function of the insert separators is as a conductor of drawing sliver which has been combed into individual fibers by adjusting the angle point of the insert separators. Damage to insert separators affects the number of slub yarns in the process of making Open-end spinning yarn. Consumption of using the separator insert continuously can make damage (eroded). The damage occurred during 20 days (four weeks) of 35.25 times of observation. The number of damaged separator inserts requires a repair whether the repair is done by patching, but in fact repair by patching is not an effective way, because the age of the patch only lasts approximately 1 week. Therefore, patch repair is not carried out, the best effort is to replace the separator insert.

Abstract

Abstract: The pressing process is a process of applying heat and pressure at a predetermined time. Temperature, time and pressure in the pressing process in the finishing department play an important role in the quality of the results of pressing garment products at PT X. Various types of main materials used in the garment production process at PT X require different conditions of temperature, time and pressing pressure, so it is necessary to know the appropriate pressing conditions for each type of material. If these three elements are not appropriate, it can give rise to several categories of defects, one of which is often experienced by PT X, namely glossing/shiny defects. The method that used in this research was carried out by experimenting with variations in pressing temperature where the time and pressure variables used were fixed. The temperature variations used in this research include 600C, 700C, 800C, 900C and 1000C.. This research aims to determine the optimum temperature that used in the pressing process in making Bigborn 2-Tuck Pants Style 3651 trousers with the main material composition being 65% Polyester and 35% Katun. The pressing results are then tested for the tensile strength of the fabric towards the warp and towards the weft of the fabric. Based on the experiments carried out, it shows that for temperature variations of 600C and 700C there are poor press defects. At varying temperatures of 800C and 900C, there are no glossing defects. At 1000C it has glossing/shiny defect. Next, to obtain the most optimum temperature conditions, the experiment continued with testing the tensile strength of the fabric. Based on the fabric tensile strength test data, an optimum temperature condition was obtained in the process of pressing Bigborn 2-Tuck Pants Style 3651 trousers, namely at a temperature of 800C. The tensile strength results obtained at a temperature of 800C were 55 kg for the tensile strength of the fabric in the warp direction and the tensile strength of the fabric in the weft direction was 45.5 kg. Keywords: temperature, pressing, glossing

Abstract

Handmade art encompasses various forms of handicraft art created by humans, including knitting. Knitting is a needlework activity that utilizes thread and hook needles. It encompasses different techniques such as embroidery, weaving, crocheting, and knitting itself. Additional activities like lacework, quilting, embroidery, needlepoint, and rugs are also considered part of the knitting realm. Although knitting and crochet are sometimes used interchangeably, they have distinct meanings. Crochet can be created using either manual or mechanical methods, employing a special hook needle to create desired shapes by hooking the thread under the previous loops. Crochet work is known for its textured appearance, with the texture varying depending on the stitches used. Examples of crochet stitches include chains, single crochet, half double crochet, double crochet, treble crochet, double trebles, slip stitch, blocks, picots, cross stitch, clusters, knots stitch, and popcorn stitch.

Abstract

Bagian PPC PT. X melaporkan, bahwa permintaan konsumen sangat tinggi, sehingga dibutuhkan proses produksi yang cepat. Setelah dilakukan pengamatan waktu produksi pada lintasan stasiun kerja produksi pencelupan menggunakan metode two bath two stage diperlukan penggunaan waktu yang cukup lama dari awal hingga akhir yaitu 210 menit, dan ditemukan waktu menganggur (idle time) pada stasiun kerja 110 menit. Hal ini mengakibatkan tidak maksimalnya hasil produksi yang diperoleh, yang berakibat pada terlambatnya waktu pengiriman pesanan. Oleh karena itu, perusahaan perlu memperbaiki lintasan produksi dari metode two bath two stage menjadi one bath two stage agar penggunaan waktu produksi menjadi lebih singkat yaitu 125 menit dan tidak ditemukan waktu menganggur (nilai idle time -5). Melalui perubahan metode, hasil produksi harus tetap memenuhi uji standar kualitas ketuaan warna (k/s), tahan luntur warna terhadap gosokan dan pencucian.

Abstract

The ecoprint technique is a technique of printing on fabric using natural dyes and making motifs from leaves manually by sticking them until the motif appears on the fabric. One of the coloring techniques in eco-print is the punching or pounding technique. This technique is considered simpler and easier to practice in everyday life. This community service activity was carried out to provide training in ecoprint pounding technique skills, provide botanical insight about leaves that have good traces using the pounding ecoprint technique, and provide entrepreneurial insight so that participants can utilize the pounding ecoprint technique to earn additional income. This service activity was carried out at Paud Bambi Al Muttaqieun which is located on Jalan Muara Selatan I No.17, Pelindung Hewan, Kecamatan Astanaanyar, Bandung City, West Java 40243. The activity was attended by 21 people including Paud teachers, parents, lecturers and student representatives. The training methods used are the lecture method, presentation method and documentation. The result of this training is that participants can apply ecoprint using the pounding technique, apart from that, the results of varying the layout of the leaf motif based on the tastes of the training participants look unique and beautiful with colors that match the original color of the leaves used.
