<![CDATA[Abstract. Production activities certainly can’t be separated from various resources. One of the resources that plays an important role is workers. In order to work optimally, workers need attention. One of the concerns that companies can give is to pay attention to the workload. Based on interviews with 10 workers in the packing section, including 6 workers in three rotary inline packer machines, 2 workers in chute, and 2 workers in loading channels. Some of the symptoms experienced by workers such as feeling lethargic, often sleepy, dizzy, not concentrating, losing passion to work, experiencing fever, dizziness and heart rate. Based on the symptoms of fatigue experienced by workers, it can be indicated that operators experience some complaints that are felt mentally, so there is a formulation of the problem in this study, namely "How to classify the level of mental workload of operators in the packing section at PT.ISemenIJawaISCG?"The data collection and processing technique used is the NASA-TLX method, to determine the level of operator workload and design the number of operators. The results obtained that there are cement bagging operators in shift 1 and shift 2 on average obtain a mental workload value exceeding 80 which means it is in the very high category. Abstrak. Kegiatan produksi tentunya tidak lepas dari berbagai sumber daya. Salah satu sumber daya yang berperan penting adalah pekerja. Agar dapat bekerja dengan maksimal, pekerja memerlukan perhatian. Salah satu perhatian yang bisa diberikan perusahaan adalah dengan memperhatikan beban kerja. Berdasarkan kegiatan wawancara kepada 10 orang pekerja di packing section, diantaranya 6 orang pekerja di tiga mesin rotary inline packer, 2 orang pekerja di chute, dan 2 orang pekerja di loading channel. Beberapa gejala yang dialami pekerja seperti perasaan lesu, sering mengantuk, pusing, tidak konsentrasi, kehilangan gairah untuk bekerja, mengalami demam, pusing dan heart rate. Berdasarkan gejala kelelahan yang dialami pekerja, dapat diindikasikan bahwa operator mengalami beberapa keluhan yang dirasakan secara mental, sehingga terdapat perumusan masalah dalam penelitian ini yaitu “Bagaimana klasifikasi tingkat beban kerja mental operator pada packing section di PT.ISemenIJawaISCG?” Adapun teknik pengumpulan dan pengolahan data yang digunakan yaitu metode NASA-TLX, guna mengetahui tingkat beban kerja operator dan merancang jumlah operator. Hasil yang diperoleh, bahwa terdapat operator pengantongan semen di shift 1 dan shift 2 rata-rata memperoleh nilai beban kerja mental melebihi 80 yang artinya masuk dalam kategori tinggi sekali.]]>
