Abstract

ABSTRAK Lotus Glove merupakan suatu kegiatan usaha yang memproduksi sarung tangan golf dan terletak di Kabupaten Sleman, Daerah Istimewa Yogyakarta. Pada proses produksi sarung tangan golf teridentifikasi beberapa waste salah satunya waste defect, terdapat produk defect sebanyak 24.746 unit dari total produksi 365.568 unit atau sekitar 6.9%. Adanya produk defect dapat memicu waste innappropriate processing, proses rework pada produk cacat memakan waktu 176,1 detik/pcs. Selain itu terindetifikasi waste waiting dan waste transportation yang diakibatkan karena banyaknya perpindahan material, terdapat 24 aktivitas tranportasi hingga total waktu yang dibutuhkan yaitu 323,10 detik dengan total jarak 161 meter. Penelitian ini bertujuan untuk mengidentifikasi penyebab waste serta merekomendasikan usulan perbaikan menggunakan metode Lean Six Sigma untuk menghilangkan waste yang teridentifikasi. Berdasarkan hasil pengolahan data menggunakan Current Value Stream Mapping diketahui presentase dari aktivitas value added sebesar 46% dengan waktu 655,86 detik, non value added sebesar 39% dengan waktu 556,57 detik, necessary non value added sebesar 15% dengan waktu 219,94 detik dan lead time sebesar 1.432,37 detik. Rata rata tingkat kinerja sigma Lotus Glove pada bulan Mei 2023 sampai Januari 2024 yaitu sebesar 3,62 sigma. Untuk mencegah adanya cacat produk dan meminimasi waste innappropriate processing dibuat Standard Operation Procedure pada area produksi. Rekomendasi perbaikan yang diberikan untuk meminimasi waste transportation dan waiting yaitu mengatur ulang tata letak pada area sewing, semi finishing dan finishing. Dengan adanya usulan perbaikan ini dibuat Future Value Stream Mapping, terdapat perubahan pada nilai presentase aktivitas VA, NVA dan NNVA, nilai VA meningkat menjadi 64% dengan waktu 655,86 detik, aktivitas NVA menurun menjadi 14% dengan waktu 142,24 detik sedangkan aktivitas NNVA meningkat menjadi 22% dengan waktu 219,94 detik. Kata kunci: Lean, Six Sigma, Waste, VSM ANALYSIS OF THE APPLICATION OF LEAN SIX SIGMA EFFORTS TO MINIMIZE WASTE IN THE GOLF GLOVE PRODUCTION PROCESS (Case Study: Lotus Glove) Lotus Glove is a company that manufactures golf gloves in Sleman Regency, Special Region of Yogyakarta. Various types of waste were found during the production of golf gloves, including 24,746 defective products out of a total production of 365,568 units, which is approximately 6.9%. Defective products being present can result in inappropriate processing waste, and the rework process for defective products takes 176.1 seconds per piece. Additionally, waiting and transportation wastes were identified due to numerous material transfers. A total of 24 transportation activities were recorded, requiring a total time of 323.10 seconds and covering a distance of 161 meters. This study aims to pinpoint the reasons for wastage and suggest enhancements through the use of the Lean Six Sigma approach to eradicate the wastage that has been identified. The data processing results through Current Value Stream Mapping show that 46% of activities add value, taking 655.86 seconds, while 39% are non-value added, taking 556.57 seconds. Additionally, 15% are necessary non-value added, taking 219.94 seconds, and the lead time is 1,432.37 seconds. The Lotus Glove Sigma performance averaged 3.62 from May 2023 to January 2024. In order to prevent product defects and reduce inappropriate processing waste, a Standard Operating Procedure has been implemented in the production area. To minimize transportation and waiting waste, it is recommended that the layout in the sewing, semi-finishing, and finishing areas be reorganized. A Future Value Stream Mapping was conducted as part of the proposed improvement, resulting in changes in the percentage values of VA, NVA, and NNVA activities. The VA value increased to 64% with a time of 655.86 seconds, NVA activity decreased to 14% at 142.24 seconds, and NNVA activity increased to 22% at 219.94 seconds.
