Abstract. In statistics, how to control quality can be done using control charts. A control chart is a graph that provides an overview to determine whether a process is in a controlled state or not. In addition to monitoring the process with an average vector, a process is also needed to control the possible shifts in the covariance matrix for two qualities with characteristics simultaneously. In its application, the variability of the service process shows that the condition is in control but after the covariance matrix is shifted the service process on the contrary shows the condition that is out of control. So, this thesis will discuss new theories or statistics to monitor covariance matrices regarding control charts, namely synthetic control charts which are a combination of Shewhart control charts and Conforming Run Length (CRL) control charts. In other words, a synthetic control chart based on two sample variants will be applied to control the service process with variable service speed and material mastery of the officers. This synthetic control chart is used because in detecting process changes it is faster and more sensitive than the general variant control chart which is the proposed control chart for the two-variable case. The data used is secondary data, namely the results of a survey on the quality of library services at BPS DKI JAKARTA. The results of monitoring the service process are out of control.Keywords: Control Chart, Covariance Matrix, Synthetic, Bivariate ProcessAbstrak. Dalam statistik, cara mengontrol kualitas dapat dilakukan dengan menggunakan diagram kendali. Diagram kendali adalah grafik yang memberikan gambaran umum untuk menentukan apakah suatu proses berada dalam keadaan terkontrol atau tidak. Selain memantau proses dengan vektor rata-rata, diperlukan juga proses untuk mengontrol kemungkinan pergeseran matriks kovarian untuk dua kualitas dengan karakteristik secara bersamaan. Dalam penerapannya, variabilitas proses pelayanan menunjukkan bahwa kondisi terkendali tetapi setelah matriks kovarians digeser proses pelayanan sebaliknya menunjukkan kondisi yang tidak terkendali. Maka, tesis ini akan membahas teori atau statistik baru untuk memantau matriks kovariansi mengenai diagram kendali yaitu diagram kendali sintetik yang merupakan gabungan dari diagram kendali Shewhart dan diagram kendali Conforming Run Length (CRL). Dengan kata lain, peta kendali sintetik berdasarkan dua varian sampel akan diterapkan untuk mengontrol proses pelayanan dengan variabel kecepatan pelayanan dan penguasaan material petugas. Diagram kontrol sintetik ini digunakan karena dalam mendeteksi perubahan proses lebih cepat dan lebih sensitif daripada diagram kontrol varian umum yang merupakan diagram kontrol yang diusulkan untuk kasus dua variabel. Data yang digunakan adalah data sekunder yaitu hasil survei kualitas pelayanan perpustakaan di BPS DKI JAKARTA. Hasil pemantauan proses layanan di luar kendali.Kata Kunci: Diagram Kontrol, Matriks Kovarian, Sintetis, Proses Bivariat |
