Abstract


Abstrak—Suatu perusahaan perlu untuk menjaga dan meningkatkan kualitas dari produk yang dihasilkan. Hal ini dapat dilakukan dengan pengendalian kualitas proses statistik (Statistical Process Control). Salah satu metode yang dapat digunakan yaitu penerapan diagram kontrol X ̅ VSSI (Variable Sample Size and Sampling Interval). Diagram kontrol X ̅ VSSI digunakan untuk mendeteksi lebih awal adanya signal – signal yang terjadi dalam suatu proses. Pada tugas akhir ini dibahas penerapan pengendalian kualitas statistik menggunakan diagram kontrol X ̅ Shewhart dan X ̅ VSSI dalam mengendalikan tingkat kecacatan produk di PT. Pacific Angkasa Abadi. Hasil perhitungan nilai ATS menunjukkan bahwa penerapan diagram kontrol X ̅ Shewhart dan X ̅ VSSI menunjukkan bahwa data proses produksi pipa besi belum terkendali secara statistik. Penerapan diagram kontrol X ̅ VSSI memberikan hasil bahwa diagram ini lebih sensitif untuk mendeteksi data yang out of control dibandingkan dengan diagram kontrol X ̅ Shewhart.
