Abstract

Efisiensi produksi pada Hauni KDF 4 sangat dipengaruhi reliabilitas garniture tape SQP-90. Penelitian ini menganalisis umur pakai fungsional tape (Sep–Des, 2022) menggunakan distribusi Weibull; parameter diestimasi dengan MLE dan divalidasi oleh plot Weibull & MoM. Hasil menunjukkan wear-out (β=4,65; η≈7,81 juta batang). MTTF ≈7,14 juta menggambarkan rerata populasi dan tidak digunakan sebagai jadwal karena ~50% unit gagal sebelum titik tersebut. Target R(t)=0,90 menghasilkan t₉₀ ≈4,82 juta (CI95%: 4,30–5,40 juta) yang diusulkan sebagai rentang SOP awal. Model biaya sederhana (harga tape, downtime 1 jam/penggantian, scrap tetap per pergantian) mengindikasikan penurunan biaya tahunan ≈66% dibanding praktik historis (~1,6 juta/tape); estimasi ekonomi ini tidak memasukkan kegagalan tak terjadwal sebelum t₉₀ dan diasumsikan kapasitas lini tidak berubah./The production efficiency of Hauni KDF 4 is greatly influenced by the reliability of SQP-90 garniture tape. This study analyzed the functional service life of tape (Sep–Dec, 2022) using Weibull distribution; parameters are estimated with MLE and validated by Weibull & MoM plots. Results showed wear-out (β=4.65; η≈7.81 million bars). The MTTF ≈7.14 million represents the average population and is not used as a schedule because ~50% of units fail before that point. The target R(t)=0.90 resulted in t₉₀ ≈4.82 million (95% CI: 4.30–5.40 million) proposed as the initial SOP range. A simple cost model (tape price, 1 hour downtime/replacement, fixed scrap per change) indicates a decrease in annual costs ≈66% compared to historical practice (~1.6 million/tape); This economic estimate does not include unscheduled failures before t₉₀ and assumes that the line capacity does not change.
