Abstract

Persaingan dalam dunia industri begitu ketat, salah satu faktor yang memengaruhi adalah adanya perkembangan teknologi. PT Serbaguna Prima merupakan bagian dari
industri yaitu perusahaan yang memiliki spesialisasi dalam pengolahan kayu dan produk yang dihasilkan seperti FJLB (Finger Joint Laminated Board), furniture, komponen rumah, serta komponen piano. Produk yang menjadi objek penelitian adalah FJLB karena FJLB sendiri merupakan produk utama yang dihasilkan oleh perusahaan. Upaya dalam mengendalikan kualitas produk perlu dilakukan untuk mempertahankan serta meningkatkan mutu produk di tengah perkembangan teknologi serta persaingan yang ada dengan menggunakan alat pengendalian kualitas, salah satunya yaitu peta kendali. Peta kendali memuat informasi berupa keberlangsungan suatu proses produksi dan dapat diketahui produk pada pengamatan ke berapa yang tidak memenuhi spesifikasi. Penelitian ini membahas mengenai perbandingan kinerja peta kendali CUSUM (Cumulative Sum) dan EWMA (Exponentially Weighted Moving Average) dalam mendeteksi keadaan out of control pada proses produksi FJLB di PT Serbaguna Prima. Sesuai dengan hasil analisis serta pembahasan yang dilakukan, terdapat beberapa sampel yang berada di luar batas kendali, artinya produksi FJLB belum terkendali secara statistik. Hasil analisis perbandingan kinerja juga menunjukkan bahwa peta kendali CUSUM memberikan kinerja atau kemampuan sensitivitas yang lebih baik sebesar 5, 714% dibandingkan dengan peta kendali EWMA dalam mendeteksi sinyal out of control

Competition in the industrial world is so tight, one of the influencing factors is the development of technology. PT Serbaguna Prima is part of the industry, namely a company that specializes in wood processing and products such as FJLB (Finger Joint Laminated Board), furniture, house components, and piano components. The product that is the object of research is FJLB because FJLB itself is the main product produced by the company. Efforts to control product quality need to be made to maintain and improve product quality in the midst of technological developments and existing competition by using quality control tools, one of which is a control chart. The control chart contains information in the form of the continuity of a production process and it can be seen how many products do not meet specifications. This study discusses the comparison of the performance of the CUSUM (Cumulative Sum) and EWMA (Exponentially Weighted Moving Average) control charts in detecting the out of control condition in the FJLB production process at PT Serbaguna Prima. In accordance with the results of the analysis and discussion carried out, there were several samples that were outside the control limits, meaning that FJLB production had not been statistically controlled. The results of the performance comparison analysis also show that the CUSUM control chart provides a better performance or sensitivity capability of 5.714% compared to the EWMA control chart in detecting the out of control signal
