Abstract

UMKM Jamu ibu Sami merupakan UMKM yang bergerak dibidang pembuatan dan pengolahan jamu tradisional yang berlokasi di dusun Watu RT 08, Argomulyo, Sedayu, Bantul, DIY. Permasalahan UMKM Jamu Ibu Sami terletak pada ketersediaan bahan baku akibat penyimpangan supplier dari aspek kualitas, harga, pengiriman, serta pelayanan. Permasalahan pada dari segi kualitas yang mempunyai permintaan bahan baku kencur sebanyak 50kg namun terdapat 2-3kg kencur yang rusak dan busuk, harga yang fluktuatif, keterlambatan pengiriman, hingga komplain yang diabaikan oleh pihak pemasok, membuat UMKM tersebut tidak dapat memaksimalkan kegiatan produksi. Dari permasalahan tersebut, dilakukan analisis pemilihan supplier menggunakan pendekatan Analytical Hierarchy Process (AHP) dan Simple additive weighting (SAW) merupakan metode pengambilan keputusan multiobjektif yang didasarkan pada penentuan faktor dan pembobotan, dan kedua metode tersebut menjadi metode untuk perbandingan hasil perangkingan supplier, sedangkan metode Taguchi Loss Function berperan untuk mengidentifikasi presentase kerugian yang ada pada setiap supplier yang dihitumg berdasarkan penilaian prioritas dari metode AHP.

Abstract

PT Indo Tirta Abadi is a company engaged in manufacturing which produces 350 ml F-tea bottle products. Based on the analysis carried out by the company, several defective products were still found, such as Gate Not Center (GTC) bottles, silver bottles and dented bottles with the highest percentage of defects, namely silver bottles at 59.5%, GTC bottles at 31%, and dented bottles at 9.5%. %. The DPMO value in the production process for 350 ml F-tea bottles in September 2023 is 613.5573 or 614 defective bottles per million production with an average sigma level of 4.75, this sigma value can be said to be good but the level is still close to low 6 sigma. The company has set a product defect target of 0.5% with a division of 0.3% being bottle defects and 0.2% being preform defects. In the calculation the average defect obtained in September 2023 is 0.006%, which is already very high. far from achieving the targets set by the company, but actually on the control chart there are still several proportions of defects that exceed the predetermined limits. Factors causing defects in 350 ml F-tea bottles consist of human, machine, method and material factors. Therefore, a proposal for improvement was obtained using the Kaizen Five M-Checklist tool to handle this problem by providing training to operators at least once every 4 months, updating work instructions by adding steps that do not exist in them and carrying out production using non-ex sorted preforms.
