Abstract
One technique used in performing statistical quality control is by poisson control chart. Poisson control chart used in data that have the same mean and varians for monitoring the number of defects in the study. In some cases, the different sample sizes influence the control chart performance. The control chart performance can be measured using average run length (ARL). The smaller ARL’s value, the better type of control chart. In this study, we used different sample sizes that is and mean . The result show the best performance of control chart is when and m = 200, because its has a smaller ARL’s value.

Parameter Estimation And Performance Of The P-Chart For Attributes Data
Summary
Salah satu bagan kendali atribut yang digunakan sebagai monitor jumlah kecacatan tiap unit produk adalah bagan kendali c dan bagan kendali u. Bagan kendali u digunakan untuk menghitung titik cacat per unit laporan pemeriksaan dalam periode yang mungkin memiliki ukuran sampel bervariasi. Jika pada bagan kendali c, kita langsung memplotkan data cacat ke dalam bagan kendali, maka pada bagan kendali u kita perlu menghitung terlebih dahulu u cacat untuk setiap n sampel. Pendekatan bagan kendali atribut c akan diaplikasikan pada kasus penderita penyakit Demam Berdarah Dengue (DBD). Beberapa penelitian terdahulu yang terkait dengan kinerja bagan kendali berdasarkan ARL diantaranya Parameter Estimation and Performance of The p-Chart For Attributes Data [4], dan Design of The C and NP Charts When The Parameters Are Estimated [3], dan Perbandingan Peta Kendali Atribut Dalam Pengendalian Kualitas Produk di PT. Sehingga pada penelitian ini bertujuan untuk menganalisis keakuratan bagan kendali poisson berdasarkan ukuran sampel
