Abstract

MOP Beauty, perusahaan kosmetik terkemuka di Indonesia, mengidentifikasi produk GWS Plump Gloss sebagai lini produk dengan tingkat cacat kemasan tertinggi. Cacat pada kemasan secara signifikan memengaruhi kepuasan pelanggan dan reputasi merek, sehingga sistem pengendalian kualitas yang efektif menjadi sangat penting. Penelitian ini bertujuan mengevaluasi efektivitas sistem inspeksi kualitas saat ini dengan menganalisis data cacat produk dari batch masuk selama periode 2023–2024. Melalui analisis Pareto, jenis cacat paling sering seperti scratches dan peeling coatings diidentifikasi, mencakup lebih dari 80% masalah kualitas. MOP Beauty saat ini menerapkan rencana pengambilan sampel tunggal dengan ukuran sampel n = 200 dan angka penerimaan c = 21, berdasarkan standar MIL-STD 105E. Operating Characteristic (OC) Curves dibangun menggunakan distribusi binomial dan hypergeometric untuk mengevaluasi kesesuaian prosedur inspeksi dengan standar Acceptable Quality Level (AQL = 10%) dan Lot Tolerance Percent Defective (LTPD = 13,5%) perusahaan. Hasil analisis menunjukkan bahwa Probabilitas Penerimaan (Pa) pada LTPD melebihi risiko konsumen (β) yang diinginkan, menandakan adanya ketidaksesuaian antara ketatnya inspeksi pemasok dan ekspektasi kualitas MOP Beauty. Rekomendasi yang diajukan mencakup pengetatan angka penerimaan menjadi c = 10 untuk menurunkan risiko β, revisi klasifikasi jenis cacat, serta penguatan prosedur inspeksi barang masuk. Perbaikan ini diharapkan dapat meningkatkan deteksi cacat, memastikan konsistensi standar kualitas, dan memperkuat kredibilitas merek di pasar kosmetik yang kompetitif. =================================================================================================================================
MOP Beauty, a leading cosmetic company in Indonesia, identified GWS Plump Gloss as having the highest packaging defect rate among its product lines. Packaging defects significantly impact customer satisfaction and brand reputation, making effective quality control crucial. This study aims to evaluate the effectiveness of the current quality inspection system by analyzing 2023–2024 defect data from incoming batches. Using Pareto analysis, the most frequent defects such as scratches and peeling coatings were identified, accounting for over 80% of quality issues. MOP Beauty currently employs a single sampling plan with a sample size of n = 200 and an acceptance number of c = 21, based on MIL-STD 105E standards. Operating Characteristic (OC) Curves were constructed using both binomial and hypergeometric distributions to assess the alignment of current inspection procedures with the company's Acceptable Quality Level (AQL = 10%) and Lot Tolerance Percent Defective (LTPD = 13.5%). The analysis revealed that the Probability of Acceptance (Pa) at LTPD exceeded the desired consumer risk (β), indicating misalignment between the supplier’s and MOP Beauty’s quality expectations. Recommendations include tightening the sampling acceptance number to c = 10 to reduce β risk, revising the defect classification standards, and strengthening the incoming inspection procedure. These improvements are expected to enhance defect detection, ensure consistency with quality standards, and reinforce brand credibility in the competitive cosmetics market.
