      Abstract
      Pengembangan suatu aplikasi harus dilakukan dengan memerhatikan faktor kebergunaan aplikasi (usability). Tiga aspek pengukuran dari usability yaitu usefulness, satisfaction dan ease of use merupakan peubah laten yang tidak dapat diukur secara langsung, sehingga analisis yang tepat digunakan adalah Struktural Equation Model-Partial Least Square (SEM-PLS). SEM bertujuan untuk mengetahui hubungan antara peubah indikator dengan peubah laten serta antar peubah laten. PLS merupakan pendekatan pada analisis SEM yang tidak memerlukan asumsi sebaran data dan jumlah minimal amatan. Pengukuran usability aplikasi Thymun digambarkan ke dalam dua model SEM-PLS. Penelitian ini bertujuan menentukan model terbaik dan mengetahui pengaruh usefulness, satisfaction dan ease of use terhadap usability aplikasi Thymun. Data yang digunakan merupakan data hasil survei kepada pengguna aplikasi Thymun sebanyak 44 amatan. Teknik pengambilan contoh yang digunakan adalah purposive sampling. Hasil penelitian menunjukkan bahwa model terbaik mempunyai ukuran kebaikan model nilai R-square sebesar 0.730 dan nilai Q2 sebesar 0.958 dengan Goodness of Fit sebesar 0.736. Peubah usefulness dan ease of use berpengaruh signifikan pada taraf nyata 5% dengan nilai koefisien jalur sebesar 0.255 dan 0.636. Sedangkan, peubah satisfaction tidak berpengaruh signifikan pada taraf nyata 5% dengan nilai koefisien jalur sebesar 0.058. Skor usability aplikasi Thymun sebesar 76.47.
       
      Mobile application development must be done by concern about its usability. The measurement aspects of usability, those are usefulness, satisfaction and ease of use are latent variables that can’t be measured directly, so the appropriate analysis is Structural Equation Model-Partial Least Square (SEM-PLS). SEM aims to determine the relationship between latent variables and their indicators and the relationship between latent variables. PLS is an approach to SEM analysis that doesn’t require the assumption of data distribution and a minimum number of observations. The measurement of usability of Thymun application is described in two SEM-PLS models.This research aimed to determine the optimal model and evaluate the effect of latent variable usefulness, satisfaction and ease of use on the usability of Thymun application. Data used in this research are the survey data from Thymun application users that have 44 observations. Purposive sampling was used as a sampling method. The results showed that the optimal model has R- square value of 0.730 and Q2 value of 0.453 with a Goodness of Fit of 0.958. Usefulness and ease of use variables affect significantly on the error rate of 5% with path coefficient values of 0.255 and 0.636. Meanwhile, satisfaction variable does not have a significant effect on the error rate of 5% with a path coefficient value of 0.058. Thymun application usability score is 76.47.
