An acceptance sampling plan plays a very important role in any quality assurance system. In this new economical design of acceptance sampling plan, three types of costs are included in the objective function by considering average outgoing quality limit (AOQL), average quality level (AQL) and lot tolerance percent defective (LTPD) constraints based on the maxima nomination sampling (MNS) method in a two-stage approach. The design of this sampling inspection plan involves the minimum average total inspection (ATI). The model is designed to minimize the summation of costs and the proposed MNS economical sampling plan is compared with the classical one. Practitioners can use the proposed model to decrease the total cost of inspection.

TEKNIK PENARIKAN SAMPEL PADA DATA ATRIBUT UNTUKPEMERIKSAAN HASIL AKHIR PRODUKSIERNANING WIDIASWANTIProgram Studi Teknik Industri, Universitas Trunojoyo MaduraJl.

PT Sinar Angkasa Rungkut I Surabaya adalah perusahaanyang memproduksi lampu. Mengacu pada pengendalian kualitas produk, teknik penarikan sampel adalahsalah satu metode yang dapat digunakan untuk melakukan pemeriksaan pada proses sealex lampu dilihatdari kondisi bulb dan seal. Tujuan penelitian ini adalah untuk mengetahui teknik penarikan sampelpenerimaan mana yang sesuai untuk pemeriksaan akhir hasil produksi bagi perusahaan. Dari keduapenarikan sampel yang digunakan, untuk penarikan sampel sekuensial hasilnya jauh lebih baik daripenarikan sampel tunggal, karena hasil perhitungan penarikan sampel sekuensial memberikan sampelyang berukuran lebih kecil. Selain itu probabilitas penerimaan (Pa ) yang dihasilkan dari penarikan sampelsekuensial menghasilkan nilai yang tepat sama dengan risiko produsen dan konsumen yang ditetapkan,yaitu sebesar 0,95 dan 0,10.Kata kunci: pengendalian kualitas, penarikan sampel tunggal, penarikan sampel sekuensial,pemeriksaanABSTRACTFinal inspection for acceptance or rejection of a product is required by the company before the productsare distributed to consumers. Sinar Angkasa Rungkut I, Ltd. Surabaya is a company that produces light.Referring to product quality control, sampling technique is one of methods that can be used to performinspection in sealex lights process which is seen from bulbs and seals condition. The purpose of this studyis to determine the acceptance sampling technique which is suitable for the final inspection of productionfor the company. From the second sampling which has been used, for sequential sampling result is muchbetter than a single sampling, because the results of sequential sampling calculations give a smaller samplesize. In addition, the probability of acceptance (Pa) resulting from sequential sampling produces exactly thesame value with the producer and consumer risks defined, namely 0.95 and 0.10.Key words: quality control, single sampling, sequential sampling, inspection

Acceptance control chart A cross between a sampling inspection plan and a control chart. Control limits are based on product specification and are intended to detect assignable causes that would lead to the production of an unacceptable fraction of nonconforming product. Acceptable quality level (AQL) Maximum per cent defective considered satisfactory for a process average. Acceptance sampling Acceptance or rejection of a product or process on the basis of sampling inspection
