Abstract

PT XXX adalah perusahaan manufaktur yang bergerak dalam pembuatan pipa PVC. Permasalahan perusahaan yang sering dialami adalah terjadi kerusakan mesin yang tiba-tiba dan tingginya waktu kerusakan mesin (downtime) ketika proses produksi berlangsung. Hal-hal tersebut mengakibatkan kelancaran proses produksi menjadi terganggu. Total downtime mesin extruder mencapai 2.202 jam pada tahun 2011 atau 10,332% yang mengakibatkan profit loss sebesar Rp 950.654.600 bagi perusahaan. Metode perawatan yang selama ini berjalan di PT XXX  kurang memperhatikan faktor keandalan/reliability mesin produksi dan lebih bersifat corrective maintenance. Penelitian ini dilakukan untuk merencanakan perawatan mesin-mesin produksi menggunakan metode Reliability Engineering dan MVSM (Maintenance Value Stream Mapping). Hasil perhitungan interval penggantian komponen dengan kriteria mean time to failure (MTTF) menunjukkan bahwa interval pergantian komponen dinamo, pulley, v-belt, tali poly, gearbox, screw press, bearing, poros, dan bushing adalah 156 hari, 140 hari, 145 hari, 156 hari, 109 hari, 89 hari, 133 hari, 160 hari, dan 91 hari. Metode perawatan Reliability Engineering dan MVSM yang diusulkan berpotensial memberikan dampak positif yaitu penurunan downtime komponen menjadi sebesar 58,3 jam/tahun, peningkatan rata-rata availability sebesar 5,3142% untuk masing-masing komponen, peningkatan maintenance efficiency sebesar 14,92%, dan peningkatan profit sebesar 856.698.320 /tahun atau sebesar 90,117%

Abstract

Many methods, rules, and techniques are used by some manufacturing companies to enhance product competitiveness by fulfilling customer needs and satisfaction possible by improving product design quality. Many researchers suggest a variety of design tools that were implemented early in the design process. Quality function deployment and Analytical hierarchy process methods are one of them. Some researchers have studied in-depth incorporating these two design techniques in product design and development by focusing on translating the consumers' desire into product design. This paper presents the review, investigates analysis, and discussion of some literature on the QFD combined AHP, which is used for product design, either re-designing existing products or designing new products. Several international journal articles have been selected, collected, and analyzed through several relevant scientific publications published in 2010-2016. An in-depth analysis has been carried out on this paper on the benefit, and drawbacks of the integration method on previous research. This paper provides suggestions based on the analysis of the development of the integration method. Hope this paper could be a reference for researchers and other manufacturing companies to implement QFD-AHP integration method in designing product
