ABSTRAK Pajar Maulana, 2025. Program Studi DIII Administrasi Logistik, Universitas Logistik dan Bisnis Internasional, Analisis Pengendalian Kualitas Produk Kain MVS Menggunakan Metode T 2 Hotelling dengan Pendekatan Multivariate Statistical Process Control (MSPC) Studi Kasus PT Daliatex Kusuma Penelitian ini bertujuan untuk menganalisis pengendalian kualitas kain MVS yang terdiri dari tiga jenis produk, yakni MVS-V Airflow, MVS-C Softblend dan MVS- H Techstretch yang diproduksi oleh PT Daliatex Kusuma. Permasalahan yang diangkat dalam penelitian ini adalah tingginya frekuensi cacat kain yang berpotensi memengaruhi mutu dan efisiensi produksi. Metode yang digunakan dalam penelitian ini adalah Multivariate Statistical Process Control (MSPC) berbasis T 2 Hotelling Chart, yang kemudian dilanjutkan dengan dekomposisi Mason, Young dan Tracy (MYT) untuk mengidentifikasi variabel penyebab utama penyimpangan proses. Data yang dianalisis mencakup jenis cacat utama yakni noda minyak mesin (oil stain), pengepresan tidak merata (finishing press defect) dan kesalahan pewarnaan (miscalculated dyeing) dari masing-masing jenis kain, serta data total produksi selama 61 periode observasi. Hasil analisis menunjukkan bahwa terdapat beberapa observasi yang berada di luar batas kendali (UCL), seperti kain MVS-V Airflow yang memiliki 5 jumlah pengamatan yang berada di luar kendali dengan didominasi cacat sebagai penyumbang utama ketidakterkendalian proses yakni paling banyak dan besar berada di finishing press defect, miscalculated dyeing dan disusul oleh oil stain. Kain MVS-C Softblend hanya memiliki pengamatan di luar batas kendali yakni di pengamatan ke- 12 dengan cacat paling berpengaruh yakni oil stain dan miscalculated dyeing, dan terakhir untuk kain MVS-H Techstretch memiliki 2 pengamatan yang berada di atas batas kendali yakni pengamatan ke-36 dan 38 dengan finishing press defect sebagai penyumbang cacat terbesar yang merepresentasikan ketidakterkendalian proses. Dekomposisi ini menggunakan nilai UCL sebesar 4,066785, yang menjadi acuan dalam proses dekomposisi.

Diploma in Logistics Administration, University of Logistics and International Business. Analysis of Quality Control for MVS Fabric Products Using the Hotelling’s T2 Method with a Multivariate Statistical Process Control (MSPC) Approach: A Case Study at PT Daliatex Kusuma. This study aims to analyze the quality control of MVS fabrics, which include three products types: MVS-V Airflow, MVS-C Sotblend, MVS-H Techstretch, manufactured by PT Daliatex Kusuma. The core issue addressed in this research is the high frequanecy of fabric defects that potentially affect product quality and production efficiency. The method employed is Multivariate Statistical Process Control (MSPC) using the Hotelling’s T2 Chart, followed by the decomposition approach proposed by Mason, Young, and Tracy (MYT) to identify the main variables contriuting to process deviations. The data analyzed consist of the three primary defect types, oil stain, finishing press defect and miscalculated dyeing, for each fabric type, along with total production data recorded over 61 observation periods. The analysis results indicate several observation fall beyond the Upper Control Limits (UCL). For MVS-V Airflow, five observations were identified as out of control, with the most significant contributing defects being finishing press defects, followed by miscalculated dyeing and oil stain. MVS-C Softblend had only one out of control observation (observation 12), primarily influenced by oil stain and miscalculated dyeing. Meanwhile, MVS-H Techstretch recorded two out of control points (Observation 36 and 38), with finishing press defects identified as the dominan cause. The decomposition process was based on a UCL value of 4.066785, which served as the reference theshold in evaluating process stability.
