      Abstract
      Papan ketik atau keyboard merupakan perangkat masukan pada komputer. Salah satu yang umum digunakan yaitu keyboard dengan layout QWERTY. Penempatan karakter alfabet pada layout keyboard disusun berdasarkan letter frequency. Penempatan karakter alfabet akan berpengaruh pada beban tangan saat mengetik. Beban tangan yang tidak seimbang antara tangan kanan dan kiri akan mengakibatkan rasa tidak nyaman bahkan cedera pada tangan. Penelitian ini bertujuan untuk mengetahui perbandingan beban tangan antara tangan kanan dan kiri berdasarkan letter frequency, mengetahui pengelompokan karakter alfabet dengan letter frequency tinggi pada tangan kanan dan kiri, serta mengetahui tebaran hotspot karakter alfabet pada layout keyboard QWERTY berdasarkan letter frequency pada dokumen skripsi mahasiswa Fakultas Matematika dan Ilmu Pengetahuan Alam (FMIPA) Institut Pertanian Bogor (IPB). Metode yang digunakan yaitu cluster analysis dan hotspot analysis dengan teknik penarikan contoh menggunakan stratified sampling. Hasil analisis beban tangan diperoleh nilai selisih persentase beban tangan pada Strata 1, 2, dan 3 bernilai negatif menunjukkan beban tangan kiri lebih besar dibandingkan beban tangan kanan. Jumlah gerombol optimum yang terbentuk pada Strata 1, 2, dan 3 sebanyak 4 gerombol. Penggerombolan karakter alfabet dengan letter frequency tinggi pada tangan kanan dan kiri relatif seimbang. Teridentifikasi adanya hotspot pada taraf nyata 5%.
       
      Keyboard is an input device on the computer. One of the commonly used is a keyboard with a QWERTY layout. The placement of alphabetic characters on the keyboard layout is arranged based on the letter frequency. The placement of alphabetic characters will affect the hand load when typing on the keyboard. An unbalanced hand load between the right and left hands will cause discomfort and even injury to the hand. This study aims to determine the comparison of the hand load between the right and left hands based on letter frequency, to determine the grouping of alphabetic characters with high letter frequency on the right and left hands, and to find out the distribution of alphabetic character hotspot on the QWERTY keyboard layout based on letter frequency on student undergraduate thesis document of Faculty of Mathematics and Natural Sciences (FMIPA) IPB University (IPB). The methods used in this research are cluster analysis and hotspot analysis with sampling technique using stratified sampling. The result of the hand load analysis obtained the value of the difference in the percentage of hand load in Strata 1, 2, and 3 negative values showed that the left hand load is greater than the right hand load. The optimum number of clusters formed in Strata 1, 2, and 3 is 4 clusters. The clusters of alphabetic characters with high letter frequency on the right and left hand are relatively balanced. It is identified that there are hotspot at a significance level of 5%.
