Abstract

DINDA ELYANA AGUSTIN. Usulan Perbaikan Tata Letak Penyimpanan Suku Cadang Dengan Metode Class-Based Storage Berdasarkan Klasifikasi FSN di PT QWERTY. Dibimbing oleh AGUNG PRAYUDHA HIDAYAT. Penelitian ini bertujuan untuk merancang ulang tata letak penyimpanan suku cadang di PT QWERTY dengan menerapkan metode class-based storage berdasarkan klasifikasi FSN. Data yang digunakan mencakup permintaan suku cadang selama Februari hingga September 2024, serta data ukuran rak dan ruang penyimpanan aktual. Analisis dilakukan melalui penghitungan Turnover Ratio (TOR) untuk mengklasifikasikan 130 jenis suku cadang dan Activity Relationship Chart (ARC) untuk menentukan kedekatan antar area. Hasil perhitungan menunjukkan bahwa 53% suku cadang tergolong fast-moving, 38,5% slow-moving, dan 8,5% non-moving. Berdasarkan nilai Total Closeness Rating (TCR), aktivitas fast-moving memiliki tingkat prioritas tertinggi. Tata letak usulan mempertimbangkan TOR, TCR, dan dimensi ruang, dengan penempatan barang fast-moving di dekat area penerimaan. Hasil perancangan ulang menunjukkan peningkatan efisiensi operasional sebesar 12,4%, ditandai dengan pengurangan jarak tempuh pengambilan barang dari 844,4 m menjadi 740,1 m.

DINDA ELYANA AGUSTIN. A Proposed Improvement of Spare Parts Storage Layout Using Class-Based Storage Method Based on FSN Classification at PT QWERTY. Supervised by AGUNG PRAYUDHA HIDAYAT This study aims to redesign PT QWERTY's spare parts storage layout by applying the class-based storage method based on FSN (fast-moving, slow-moving, and non-moving) classification. The data includes spare parts demand from February to September 2024 and the dimensions of existing racks and storage space. The analysis involved calculating the Turnover Ratio (TOR) to classify 130 types of spare parts and using an Activity Relationship Chart (ARC) to assess spatial proximity between storage zones. The results show that 53% of the items are categorized as fast-moving, 38.5% as slow-moving, and 8.5% as non-moving. Based on Total Closeness Rating (TCR), fast-moving activities have the highest priority. The proposed layout integrates TOR, TCR, and space dimensions, with fast-moving items closer to the receiving area. The redesigned layout results in a 12.4% increase in operational efficiency, reducing the picking distance from 844.4 meters to 740.1 meters.
