Abstract

ABSTRAK Efektivitas operasional mesin produksi memiliki peran krusial dalam industri pakan ternak, terutama pada produksi konsentrat ruminansia yang melibatkan penggilingan, pencampuran, dan pengemasan. PT Merapi Farm Agroedutech menghadapi kendala pada mesin ribbon mixer, khususnya kerusakan pada bulan desember 2024 yang mencapai 385 menit dengan waktu perbaikan selama 72 menit, ini menjadi kerusakan terlama selama periode penelitian. Tujuan dari penelitian ini adalah untuk meningkatkan efektivitas operasional produksi konsentrat ruminansia dari mesin ribbon mixer dengan menentukan nilai Overall Equipment Effectiveness (OEE), dilanjutkan pengukuran Six Big Losses untuk mengidentifikasi tingkat kerugian yang dialami, dan usulan strategi pencegahan dari kerugian menggunakan metode Fault Tree Analysis (FTA). Pengukuran menggunakan Overall Equipment Effectiveness (OEE) menunjukkan nilai rata-rata 94,19%, dengan availability 96,49%, performance 99,86%, dan quality 97,75%. Analisis Six Big Losses mengidentifikasi tiga kerugian utama, yaitu idling & minor stoppages losses, breakdown losses, dan process defect losses. Melalui Fault Tree Analysis (FTA), ditemukan delapan basic event penyebab kerugian utama, seperti bahan baku menggumpal, kelebihan bahan pada conveyor, hingga kurangnya pelumasan. Strategi pencegahan yang diusulkan meliputi inspeksi rutin, pengaturan kelembapan, penggunaan material standar, pelatihan operator, dan penerapan otomatisasi. Implementasi strategi berbasis FTA ini terbukti efektif dalam meminimalkan kerugian, meningkatkan keandalan mesin, dan menjaga kualitas produk secara berkelanjutan, sehingga mendukung daya saing perusahaan di industri pengolahan pakan ternak. Kata kunci: Overall Equipment Effectiveness (OEE), Six Big Losses, Fault Tree Analysis (FTA), preventive maintenance, efektivitas produksi. ABSTRACT Operational effectiveness of production machines plays a crucial role in the animal feed industry, especially in ruminant concentrate production, which involves grinding, mixing, and packaging. PT Merapi Farm Agroedutech faced problems with its ribbon mixer machine, particularly a breakdown in December 2024 that reached 385 minutes with a repair time of 72 minutes. This was the longest breakdown during the research period. The purpose of this study is to improve the operational effectiveness of ruminant concentrate production from the ribbon mixer machine. It is conducted by determining the Overall Equipment Effectiveness (OEE) value, followed by measuring the Six Big Losses to identify the level of losses experienced, and proposing a loss prevention strategy using the Fault Tree Analysis (FTA) method. Measurements using Overall Equipment Effectiveness (OEE) showed an average value of 94.19%, with availability of 96.49%, performance of 99.86%, and quality of 97.75%. The Six Big Losses analysis identified three main losses: idling and minor stoppages, breakdown losses, and process defect losses. Through Fault Tree Analysis (FTA), eight basic events were identified as the main causes of losses, such as raw material clumping, excess material on the conveyor, and lack of lubrication. Proposed preventive strategies include routine inspections, humidity control, use of standard materials, operator training, and automation. Implementation of this FTA-based strategy proves effective in minimizing losses, improving machine reliability, and maintaining product quality sustainably. Thus it is supporting the company's competitiveness in the animal feed processing industry. Keywords: Overall Equipment Effectiveness (OEE), Six Big Losses, Fault Tree Analysis (FTA), preventive maintenance, production effectiveness.
