Penelitian ini menganalisa kebutuhan tenaga perawat pelaksana di Ruang Rawat Inap Teratai berdasarkan beban kerja menggunakan time and motion study yang kemudian diolah berdasarkan metode WISN dan metode Ilyas. Penelitian secara observasional dilaksanakan selama 7 hari kepada 7 orang perawat pelaksana untuk mengetahui beban kerja perawat.
