P PTPN III PARAS merupakan perusahaan yang bergerak di bidangpengolahan minyak mentah. Penelitian ini dilakukan pada operator yangbekerja pada stasiun pengolahan terdiri dari perebusan, press, boiler dankamar mesin. Operator perebusan ditemukaan adanya perasaan cemas dankondisi kerja monoton saat memonitori aktivitas mesin. Operator pressmengalami kejenuhan saat memonitori mesin digester dan screw danperasaan cemas terhadap bahaya terjatuh. Operator boiler mengalamikelelahan otot dan mengeluarkan keringat berlebihan. Operator kamarmesin merasa cemas akan bahaya tersengat listrik dan kondisi bising.Kondisi lingkungan kerja pada pabrik tidak ergonomis. Penelitian inimenggunakan metode NASA-TLX sebagai pengukuran beban kerja mentalsubjektif dalam menilai beban kerja yang dirasakan operator dan metodeCVL menggunakan pengukuran denyut nadi selama bekerja sebagaipenilain beban kerja fisik operator. Dalam penelitian ini bertujuanmemberikan usulan perbaikan mengurangi beban kerja mental dan bebankerja fisik. Hasil pengukuran NASA-TLX diperoleh WWL operator danhelper perebusan sebesar 83,34 dan 82 kategori sangat tinggi. Operator danhelper press diperoleh nilai WWL sebesar 100 dan 96 kategori sangat tinggi.Operator dan helper boiler diperoleh nilai WWL 86 dan 91,34 kategorisangat tinggi. Operator kamar mesin dengan nilai 75 kategori tinggi danhelper sebesar 92 kategori sangat tinggi. Hasil perhitungan CVL didapatkanoperator boiler dengan nilai sebesar 31,61 dan helper boiler sebesar 31,91sehingga diperlukan perbaikan. Berdasarkan penelitian tersebut, makausulan perbaikan yang diberikan yaitu pelatihan manajemen stress yangdilakukan selama 2 minggu dan praktik manajemen stress dengan senampagi sebelum bekerja serta memberikan penambahan cyclone turbinventilator tipe L-75 dengan kemampuan daya hisap sebesar 117,75m3/menit di stasiun boiler dengan jumlah kebutuhan 13 buah.

P PTPN III PARAS is a company engaged in the processing of crudeoil. This research was conducted on operators working at processingstations consisting of boiling, press, boiler and engine room. Boilingoperators were found to have feelings of anxiety and monotonous workingconditions when monitoring machine activities. The press operatorexperienced boredom while monitoring the digester and screw machinesand felt anxious about the danger of falling. Boiler operators experiencemuscle fatigue and sweat profusely. Engine room operators are concernedabout the dangers of electric shock and noisy conditions. The workingenvironment conditions in the factory are not ergonomic. This study usesthe NASA-TLX method as a subjective mental workload measurement inassessing the operator's perceived workload and the CVL method uses pulsemeasurement during work as an assessment of the operator's physicalworkload. This study aims to provide suggestions for improvements toreduce mental workload and physical workload. The NASA-TLXmeasurement results obtained WWL operators and boiling helpers of 83.34and 82 categories very high. Operator and helper press obtained WWLvalues of 100 and 96 very high categories. Operators and boiler helpersobtained WWL 86 and 91.34 very high categories. Machine room operatorwith a score of 75 in the high category and the helper in 92 in the very highcategory. The results of the CVL calculation are obtained by the boileroperator with a value of 31.61 and the helper boiler of 31.91 so thatimprovements are needed. Based on this research, the proposedimprovements are stress management training carried out for 2 weeks andstress management practices with morning exercise before work as well asproviding the addition of a cyclone turbine ventilator type L-75 with asuction capacity of 117.75 m3/minute at the station. boiler with a totalrequirement of 13 pieces
