Abstract

Tujuan penelitian ini adalah mengukur beban kerja karyawan pada lini produksi PT.X di Driyorejo. Terdapat sejumlah karyawan pada masing-masing bagian, yaitu 2 orang pada bagian Penggilingan, 2 orang di bagian Packing, 2 orang di bagian Perebusan, serta 2 orang di bagian Pemotongan Bahan. Pengukuran beban kerja ini menggunakan metode NASA-TLX (National Aeronautics and Space Administration Task Load Index). Dalam metode ini terdapat dua tahap pengukuran, yaitu tahap pembobotan dan tahap pemberian rating. Dalam perhitungan tersebut mengacu pada 6 indikator NASA TLX, yaitu KF, KM, KW, P, TU, serta TF. Hasil dari pengukuran beban kerja mental karyawan menunjukkan bahwa indikator TU (Tingkat Usaha) memiliki nilai yang tertinggi daripada indikator lainnya. Sedangkan indikator TF (Tingkat Frustasi) menjadi yang terendah diantara indikator lainnya. Dan hasil akhir dari perhitungan nilai skor beban kerja mental karyawan PT. X skor NASA-TLX rata-ratanya ialah sebesar 79,25. Artinya untuk nilai ini menurut NASA – TLX termasuk pada kategori beban kerja mental yang berat. Adapun bagian pekerjaan dengan tingkat beban kerja tinggi ada pada bagian Packing dan Penggilingan, tingkat beban kerjanya yaitu sebesar 82,666 di bagian Packing dan 80,666 pada bagian Penggilingan.ABSTRACTThe purpose of this study is to measure the workload of employees on the PT.X DRIYOREJO production line. Each of which is 2 in the Milling section, 2 in the Packing section, 2 in the Boiling section and 2 in the Material Cutting section. Measurements were made using the NASA-TLX (National Aeronautics and Space Administration Task Load Index) method. In this method there are two stages of measurement, namely the weighting stage and the rating stage. The calculation will refer to 6 NASA TLX indicators, namely KF (Physical Demands), KM (Mental Demands), KW (Temporal Demands), P (Performance), TU (Efforts), TF (Frustration). The results of measuring the mental workload of employees show that the TU (Business Level) indicator has the highest value than other indicators. Meanwhile, the TF (Frustration Level) indicator is the lowest among other indicators. And the final result of calculating the mental workload of employees, the average NASA-TLX score is 79.25. This means that the category of mental workload of employees according to the NASA – TLX method is included in the category of heavy mental workload. The work section with a high level of workload is in the Packing and Milling section, the workload level is 82,666 in the Packing section and 80,666 in the Milling section.

Abstract

Ship launching is one of the stages of ship production before the ship is handed over to the owner, which marks the beginning of the ship's life. With the development of technology at this time, various launching methods have been developed, one of which is the launching method using an air bag system. Launching using air bags has many advantages compared to conventional launching methods that have been used so far. Pre-launch calculations are performed to avoid risks during the launch. Launching using air bags begins with calculating the weight plan of the ship launch and the preparation of the air bag layout. Using CB/T 3837:1998 Technological Requirements for Ship Upgrading or Launching Relying on Air Bags, Shipbuilding Industry Standard, and ISO 14409:2011 ships and marine technology-ship launching air bags, the number of air bag requirements and layout can be determined to support the ship launching process. The passenger ship, with an length overall of 62.80 metres, is planned to have a launch weight of 1058.881 tons. By using the QG6 high-bearing capacity air bag model with 6 layers of cord fabric with a diametre of one metre and a contact length between the air bag and the ship's body of ten metres, a total of 11 air bags are required in a linear arrangement to support the launch of a passenger ship. The distance between air bags is 2.07 metres to 5.736 metres, the longer the distance between air bags, the greater the load supported by each air bag.
