Abstract
UMKM AR Genteng KTL is a type of small and medium industrial business that is included in the building materials industry business category that processes clay as the main raw material source in the production process into finished goods in the form of roof tiles. Based on data on the amount of production in the period January 2024 to February 2024, a problem was found, namely that 5% of the total tile production had defects and had resulted in a loss of IDR 9.100 per production. The purpose of this study is to determine the type of CTQ, determine the DPMO value and sigma value, determine the factors causing product defects, provide suggestions for improvements to the production process, and provide and improvement strategy for the cause of process failure. In the MSME, there are 4 CTQs of defective roof tile products, namely defects in rupture, cracking, chipping, and burnt color. Based on the research results, before the improvement, the percentage value of product defects was 0,65% and the DPMO value was 1627 with a sigma value of 4,47. Factors that cause product defects are material, environment, and method factors. Proposed improvements are made by applying the results of the Taguchi experimental design combination of optimal factors and levels, namely 8 hours of drying time and 24 hours of drying time. After the improvement, the average percentage value of product defects is 0,42% and the DPMO value is 1055 with a sigma value of 4,59.

| Additional Information: | UMKM AR Genteng KTL merupakan jenis usaha industri kecil dan menengah yang termasuk dalam kategori usaha industri bahan bangunan yang mengolah tanah liat sebagai sumber bahan baku utama dalam proses produksi menjadi barang jadi berupa genteng. Berdasarkan data jumlah produksi pada periode bulan Januari 2024 hingga Februari 2024 ditemukan permasalahan yaitu terdapat 5% dari total produksi genteng mengalami defect dan telah mengakibatkan kerugian sebesar Rp9.100 per produksi. Tujuan penelitian ini yaitu menenentukan jenis CTQ, menentukan nilai DPMO dan nilai sigma, menentukan faktor penyebab cacat produk, memberikan usulan perbaikan pada proses produksi, dan memberikan strategi perbaikan terhadap penyebab kegagalan proses. Pada UMKM ini terdapat 4 CTQ dari produk genteng yang defect, yaitu cacat pecah, retak, gompal, dan warna gosong. Berdasarkan hasil penelitian, sebelum dilakukannya perbaikan didapatkan nilai persentase cacat produk sebesar 0,65% dan nilai DPMO sebesar 1627 dengan nilai sigma sebesar 4,47. Faktor yang menyebabkan produk defect adalah faktor material, environment, dan method. Usulan perbaikan dilakukan dengan menerapkan hasil kombinasi desain eksperimen Taguchi dari faktor dan level yang optimal yaitu lama pengeringan 8 jam dan lama penjemuran 24 jam. Setelah dilakukan perbaikan, nilai rata-rata persentase cacat produk sebesar 0,42% dan nilai DPMO sebesar 1055 dengan nilai sigma sebesar 4,59. | |||||||||
