Abstract

The garment industry is one of the fastest-paced production environments, where speed and accuracy are crucial for meeting global customer demand. Cycle time plays an important role in satisfying the speed factor as it represents the overall time needed to produce a single piece of a product. Maintaining an appropriate cycle time is key to achieving production line balance. This study aims to analyze the cycle time of men's jacket production on a sewing line in an Indonesian garment industry by comparing the actual cycle time with the standard cycle time based on the operation breakdown for each production process step. Four significant discrepancies in actual cycle time were identified, ranging from 16% to 95%, indicating that the actual cycle time was significantly longer than the standard cycle time. The root cause of the highest cycle time was analyzed using Fishbone and 5 Whys analysis to understand the problem from each factor and sub-factor. Six improvement action plans were proposed and implemented, resulting in a 57.81% reduction in actual cycle time, from 127.66 seconds to 53.85 seconds, making it 17.66% faster than the standard cycle time. Furthermore, the total output per hour increased by approximately 216.67%, from 12 pieces to 38 pieces. This result implies that the study successfully identified the root of the problem on the sewing line and managed to increase production output.

Abstract

Divisi Weaving PT X pada Bulan Desember 2021 memproduksi kain grey sepanjang 1.952.612,09 meter dengan efisiensi 70,65% dan total grade D (aval) sebanyak 3,73%. Hasil yang dicapai belum memenuhi target dengan panjang 2.150.000 meter, efisiensi lebih dari 75%, dan grade D kurang dari 2%. Oleh karena itu, dilakukan penelitian dengan fokus perhitungan nilai Overall Equipment Effectiveness (OEE) dan analisis Six Big Losses pada periode bulan Maret 2022 sebagai upaya untuk meningkatkan produktivitas mesin AJL Toyota JAT810. Berdasarkan hasil penelitian diperoleh nilai availability sebesar 91,88%, performance efficiency sebesar 78,27%, dan rate of quality product sebesar 99,06%. Rata-rata nilai OEE sebesar 72,07% dan berada di bawah nilai standar (>85%). Nilai dari six big losses yaitu breakdown losses sebesar 8,81%, setup and adjustment losses sebesar 8,18%, idling and minor stoppage losses sebesar 56,95%, reduced speed sebesar 24,59%, process defect sebesar 1,43%, dan reduced yield sebesar 0,04%. Berdasarkan analisis diagram fishbone, tidak tercapainya nilai standar OEE (>85%) disebabkan oleh faktor mesin, metode, manusia, lingkungan, dan material. Usulan untuk mengatasi permasalahan tersebut sebagai upaya untuk meningkatkan produktivitas mesin yaitu memprediksi lifetime spare part dalam penyusunan jadwal pemesanan dan kontrol persediaan spare part, meningkatkan skill kerja operator dengan memberikan pelatihan, pengendalian terhadap stok beam, pengendalian kualitas benang lusi dan pakan, serta pengontrolan terhadap temperatur dan RH.

Abstract

The integration of ultra-high frequency radio frequency identification (UHF RFID) technology presents a transformative solution to inventory management challenges in the textile industry. This study examines the implementation of a web-based inventory management system incorporating UHF-RFID technology at AK-Tekstil Solo, focusing on its impact on inventory accuracy, operational efficiency, and product traceability. The developed system facilitates real-time tracking of yarn products, streamlines inventory audits, and minimizes manual errors, resulting in substantial improvements in inventory control and warehouse management processes. By enabling automated data capture and tracking, UHF-RFID technology supports the transition to smart warehousing by providing real-time insights into inventory movements. The findings demonstrate that UHF-RFID technology offers significant advantages, including enhanced inventory visibility, cost savings, and improved customer satisfaction through better product availability. Despite potential implementation challenges, the study shows that the long-term benefits of UHF-RFID integration outweigh the initial costs, proving it to be an effective solution for optimizing inventory management in the textile industry. Future research may explore the integration of complementary technologies such as the internet of things (IoT) and artificial intelligence (AI) to further enhance UHF-RFID enabled inventory management systems.

Abstract

This study aims to design and develop a yarn linear density measurement device based on an Arduino Uno microcontroller integrated with an online database recording system (Google Sheet). Conventional measurement of yarn linear density is still carried out manually using a standard reeling device, which requires a relatively long time and is prone to recording errors. Therefore, this research offers an automated and digitized testing solution. The research method includes the mechanical and electronic design of the measuring device, validation of measurement results against a calibrated standard instrument, and the development of a database system and Android application for recording test results. The tests were conducted on three types of yarns (Ne? 19, Ne? 23, and Ne? 31) with ten repetitions each. The two-way ANOVA results indicated no significant differences between the prototype and the standard instrument (F(1,9) = 0.305; p = 0.594), among the tested yarn types (F(2,18) = 2.061; p = 0.156), and in their interaction (F(2,18) = 1.870; p = 0.183), confirming that the prototype is statistically valid. The database-based tracking system also demonstrated a 100% data transmission success rate with a response time of less than two seconds. This study successfully integrates physical measurement and laboratory digitalization, resulting in a prototype of an IoT-based yarn linear density testing system that can be implemented in modern textile testing laboratories, supporting the transformation toward Textile Industry 4.0. ABSTRAK Penelitian ini bertujuan untuk merancang dan mengembangkan alat ukur densitas linear benang berbasis mikrokontroler Arduino Uno yang terintegrasi dengan sistem pencatatan hasil uji berbasis database daring (Google Sheet). Pengukuran densitas linear benang secara konvensional masih dilakukan secara manual menggunakan alat reeling standar yang membutuhkan waktu relatif lama dan rentan terhadap kesalahan pencatatan. Oleh karena itu, penelitian ini menawarkan solusi berbasis otomasi dan digitalisasi pengujian. Metode pelaksanaan meliputi tahap perancangan mekanik dan elektronik alat ukur, pengujian dan validasi hasil alat terhadap alat standar terkalibrasi, serta pengembangan sistem database dan aplikasi Android untuk pencatatan hasil pengujian. Pengujian dilakukan pada tiga jenis benang (Ne? 19, Ne? 23, dan Ne? 31) dengan sepuluh kali pengulangan masing-masing. Hasil analisis ANOVA dua arah menunjukkan tidak terdapat perbedaan yang signifikan antara alat rancangan dan alat standar (F(1,9) = 0,305; p = 0,594), maupun antarjenis benang yang diuji (F(2,18) = 2,061; p = 0,156), serta tidak ada interaksi signifikan antara keduanya (F(2,18) = 1,870; p = 0,183), sehingga alat dapat dikatakan valid. Sistem tracking berbasis database juga menunjukkan tingkat keberhasilan pengiriman data mencapai 100% dengan waktu respon kurang dari dua detik. Penelitian ini berhasil mewujudkan integrasi antara sistem pengukuran fisik dan digitalisasi laboratorium tekstil, serta menjadi prototipe awal sistem pengujian densitas linear berbasis Internet of Things (IoT) yang dapat diimplementasikan di laboratorium pengujian tekstil modern dan mendukung transformasi menuju industri tekstil 4.0.
