Terdapat permasalahan yang terjadi pada departemen tersebut, yaitu adanya pemborosan (waste) dilantai produksi dan adanya complain dari internal customer yaitu Departemen Weaving. Penelitian ini bertujuan untuk menghitung nilai sigma dari kondisi eksisting dan mengurangi jumlah defect yang berada di lantai produksi. Langkah yang dilakukan dalam penelitian ini disesuaikan dengan framework DMAIC. Fase Define dimulai dari identifikasi kondisi eksisting melalui penggambaran Value Stream Mapping (VSM), activity Classification Diagram, dan penyebaran kuisioner menggunakan AHP untuk identifikasi waste kritis, serta identifikasi dari macam-macam Critical To Quality (CTQ). Pemborosan yang paling sering terjadi pada lantai produksi adalah adanya defect. Fase Measure yaitu dimulai dengan penghitungan nilai sigma dan pemilihan defect yang kritis menggunakan pareto diagram. Dari hasil penelitian rata-rata nilai sigma pada proses produksi benang yaitu sebesar 3,5 sigma. Fase Analyze yaitu dengan dilakukan analisis akar permasalahan adanya defect dengan menggunakan tools Root Cause Analysis (RCA). Setelah itu, dirancang kuesioner Failure Mode and Effect Analysis (FMEA) yang diisi oleh salah satu orang ahli di perusahaan untuk menilai tingkat severity, occurrence, dan detection dari masing-masing akar permasalahan hingga didapatkan nilai Risk Priority Number (RPN). Dari hasil penelitian didapatkan tiga akar permasalahan yang memiliki nilai RPN tertinggi yaitu proses perawatan dan pengecekan komponen mesin produksi benang kurang baik, operator kurang memperhatikan standardisasi dalam peraturan (setting) mesin, dan komponen mesin pada proses produksi mengalami aus. Pada fase Improve dibangun rekomendasi perbaikan sesuai dengan akar permasalahan tersebut. Rekomendasi perbaikan yang diusulkan adalah adanya pembuatan SOP yang baik dan benar serta ditempel pada setiap mesin produksi, pembuatan form pengontrolan kondisi mesin, dan adanya pengadaan pengawas lapangan serta pemberia training secara rutin kepada operator dengan interval 3 bulan sekali. Dengan adanya improvement tersebut, defect dapat direduksi sebesar 45,72% dan nilai sigma meningkat menjadi 3,77 sigma.

The advantages of QFD is to translate customer need into a technical response. But QFD has some disadvantages related to the difficulties in distinguishing the difference of needs between consumers, difficulties to fulfill the needs of different consumer groups, and the exietence of conceptual gap between consumers and companies. The proposed method to overcome these disadvantages is conjoint analysis. The main advantage of conjoint analysis is the ability to get the optimal design combination for products or services based on consumers' preference. The result of conjoint analysis, estimation of perceived value, and integration of QFD can be used to know the preference market needs among consumers, identify the office desk, determine consumer segments and technical respons, and estimate the additional price of office desk attributes as an effort to the development of the office desk. In overall the best Office desk combination results based on consumers' preference of Office desk is the white color without additional drawers or supporting features, with table size is 120x60x75 cm and footstool. Segmentation based on preferences resulting in three clusters, namely size, color, and availability of drawer. The highest technical response to be the company's priority in meeting the needs of consumers is to make the proper hole connection. Based on the perceived value, the company is capable to predict that the additional prices of 1 drawer is Rp.1-Rp.500.000, the addition price of 2 drawers is Rp.800,000 - Rp.900.000, and the addition price of the foundation of the foot is Rp.50.000 - Rp.150.000, and the additional price of supporting features is Rp.150.000-Rp.250.000.Keywords: Quality Function Deployment (QFD), conjoint analysis, segmentation and perceived value.AbstrakKeunggulan QFD adalah menterjemahkan customer need menjadi respon teknis. Namun QFD mempunyai kekurangan terkait sulit membedakan antara beragam kebutuhan konsumen yang bertentangan, sulit memenuhi kebutuhan konsumen yang berbeda kelompok, dan kesenjangan konseptual antara konsumen dan perusahaan. Untuk melengkapi kekurangan QFD, diusulkan metode conjoint analysis. Keunggulan utama conjoint analysis mampu mendapatkan kombinasi desain yang optimal untuk produk yang melekat pada preferensi konsumen. Hasil integrasi QFD dan conjoint analysis serta estimasi perceived value dapat mengetahui preferensi konsumen meja kantor, mengidentifikasi segmen konsumen meja kantor, menentukan respon teknis, dan mengestimasi harga penambahan atribut meja kantor sebagai upaya pengembangan meja kantor. Secara keseluruhan hasil kombinasi meja kantor terbaik berdasarkan preferensi konsumen meja kantor adalah warna putih, tidak membutuhkan penambahan fitur laci, tidak membutuhkan penambahan fitur pendukung, ukuran meja 120x60x75 cm, dan terdapat tumpuan kaki. Berdasarkan segmentasi preferensi terbentuk tiga klaster, yaitu klaster warna, klaster ukuran, dan klaster ketersediaan laci. Secara keseluruhan respon teknis yang menjadi prioritas perusahaan untuk memenuhi kebutuhan konsumen adalah pembuatan lubang sambungan yang tepat. Berdasarkan hasil perceived value, perusahaan dapat memperkirakan harga penambahan 1 laci berkisar Rp.1 - Rp.500.000, penambahan 2 laci adalah Rp. 800.000 – Rp. 900.000, penambahan tumpuan kaki Rp. 50.000 – Rp. 150.000, dan penambahan fitur pendukung Rp. 150.000-Rp. 250.000.Kata kunci: Quality Function Deployment (QFD), conjoint analysis, segmentasi, dan perceived value

This service is still relatively new because it is operating in 2019 and evaluation is needed so that efficiency increases by reducing waste. In this study, the method used is Lean Service because the delivery service is in the service sector. The tools used in this research are Value Stream Mapping (VSM) and DEMATEL. VSM is used to analyze the value flow in the service process. VSM results can indicate a process that is not needed. After that, it is continued by identifying process flow waste and determining critical waste in these services. Determination of critical waste is done using DEMATEL. DEMATEL is a method used to analyze the cause-effect relationship of a complex system. The results showed that the main waste factor in logistics services is customer activity reporting incoming cargo. This waste can be repaired by moving the office location into one room with a new warehouse and activity flow.
