Perbaikan Efektivitas Mesin Breadline di CV Sawargi Bakery

Abstract

Abstract. CV Sawargi Bakery is a company engaged in the food industry with its main product being kopyor bread. In its production activities, the company implements a semi-automatic system relying on a breadline machine as the main equipment, so the performance of the machine is the focus of the research. In practice, the effectiveness of the breadline machine often decreases due to disruptions and unplanned downtime that cause various production losses. Therefore, a comprehensive evaluation of the machine's performance is needed to identify and minimize the losses that occur. This study uses the Overall Equipment Effectiveness (OEE) method by measuring three main parameters, namely availability, performance, and quality. Next, an analysis of the Six Big Losses was conducted and the main causes of low machine effectiveness were identified using a Pareto diagram and a fishbone diagram. The results showed that the average OEE value of the breadline machine in November and December 2024 were 63.84% and 62.46%, respectively, with availability values ​​of 86.20% and 86.95%, performance of 75.57% and 73.54%, and quality of 98%, respectively. The Six Big Losses analysis showed that the largest losses came from setup and adjustment losses, accounting for 42%. Based on these results, recommendations for improvement focused on refining setup procedures, operator training, and optimizing machine settings to increase production efficiency.

Abstrak. CV Sawargi Bakery merupakan perusahaan yang bergerak di bidang industri pangan dengan produk utama roti kopyor. Dalam aktivitas produksinya, perusahaan menerapkan sistem semi otomatis dengan mengandalkan mesin breadline sebagai peralatan utama, sehingga kinerja mesin tersebut menjadi fokus penelitian. Dalam praktiknya, efektivitas mesin breadline sering mengalami penurunan akibat terjadinya gangguan dan downtime tidak terencana yang menimbulkan berbagai losses produksi. Oleh karena itu, diperlukan evaluasi kinerja mesin secara menyeluruh untuk mengetahui dan meminimalkan losses yang terjadi. Penelitian ini menggunakan metode Overall Equipment Effectiveness (OEE) dengan mengukur tiga parameter utama, yaitu availability, performance, dan quality. Selanjutnya dilakukan analisis Six Big Losses serta identifikasi penyebab utama rendahnya efektivitas mesin menggunakan diagram Pareto dan diagram fishbone. Hasil penelitian menunjukkan bahwa nilai rata-rata OEE mesin breadline pada bulan November dan Desember 2024 masing-masing sebesar 63,84% dan 62,46%, dengan nilai availability sebesar 86,20% dan 86,95%, performance sebesar 75,57% dan 73,54%, serta quality masing-masing sebesar 98%. Analisis Six Big Losses menunjukkan bahwa kerugian terbesar berasal dari setup and adjustment loss dengan persentase sebesar 42%. Berdasarkan hasil tersebut, rekomendasi perbaikan difokuskan pada penyempurnaan prosedur setup, pelatihan operator, dan optimasi pengaturan mesin untuk meningkatkan efektivitas produksi.
