Abstract
PT XYZ merupakan perusahaan agroindustri berbasis kelapa sawit yang memproduksi kemasan jerigen secara internal melalui proses blow molding. Pada area produksi jerigen ditemukan permasalahan produktivitas, khususnya pada mesin MC31 yang memiliki nilai Overall Equipment Effectiveness (OEE) sebesar 88,19% pada Februari 2026, dengan komponen performance sebagai nilai terendah. Penelitian ini bertujuan untuk menganalisis performance loss dan ketidaksinkronan man-machine pada proses blow molding MC31 serta menyusun usulan perbaikan produktivitas. Metode yang digunakan meliputi stopwatch time study, analisis cycle time dan takt time, man-machine chart, serta simulasi skenario perbaikan menggunakan FlexSim. Hasil penelitian menunjukkan bahwa cycle time aktual MC31 sebesar 62 detik/unit masih lebih besar dibandingkan takt time acuan sebesar 56 detik/unit. Selain itu, aktivitas operator belum tersinkronisasi secara optimal dengan siklus mesin, ditunjukkan oleh utilisasi operator sebesar 66,13%. Skenario terbaik adalah kombinasi penurunan cycle time menjadi 58 detik dan konfigurasi satu operator untuk dua mesin. Skenario ini mampu meningkatkan output dari 460 unit/shift menjadi 496 unit/shift, meningkatkan utilisasi operator menjadi 92%, serta berpotensi meningkatkan OEE MC31 menjadi 94,66%. Pada analisis kolektif lini 25 L, penerapan konsep perbaikan pada beberapa mesin dengan karakteristik serupa menunjukkan bahwa kebutuhan produksi harian dapat terpenuhi.

PT XYZ is a palm oil-based agro-industrial company that produces jerrycan packaging internally through the blow molding process. A productivity issue was identified in the jerrycan production area, particularly on machine MC31, which recorded an Overall Equipment Effectiveness (OEE) value of 88.19% in February 2026, with performance as the lowest component. This study aims to analyze performance loss and man-machine synchronization issues in the MC31 blow molding process, as well as to develop productivity improvement proposals. The methods used include stopwatch time study, cycle time and takt time analysis, man-machine chart, and improvement scenario simulation using FlexSim. The results show that the actual cycle time of MC31 was 62 seconds/unit, which was higher than the reference takt time of 56 seconds/unit. In addition, operator activities were not optimally synchronized with the machine cycle, as indicated by an operator utilization of 66.13%. The best scenario was the combination of reducing the cycle time to 58 seconds and assigning one operator to handle two machines. This scenario increased output from 460 units/shift to 496 units/shift, increased operator utilization to 92%, and potentially improved the OEE of MC31 to 94.66%. In the collective analysis of the 25 L production line, applying the improvement concept to several machines with similar process characteristics showed that the daily production requirement could be fulfilled.
