Abstract
Perkembangan teknologi di indonesia sangat cepat dan hal ini diiringi dengan
banyaknya produk elektronik yang digunakan masyarakat. Salah satunya lemari es yang
berfungsi untuk mendinginkan makanan dan minuman menjadi alat elektronik penting bagi
masyarakat saat ini. Produksi lemari es di PT Sharp Electronics Indonesia memiliki dua jenis,
yaitu satu pintu dan dua pintu kedua jenis ini merupakan produksi dalam negeri dengan
kualitas yang menjanjikan serta inovasi model yang terus berkembang. Namun, monitoring
proses produksi yang dilakukan di PT Sharp Electronics Indonesia dilakukan secara manual
dan belum menerapkan monitoring menggunakan diagram kendali. Oleh karena itu,
dibutuhkan analsis pengendalian kualitas dengan menggunakan diagram kendali u, demerit,
dan demerit berbasis AHP untuk memaksimalkan proses produksi lemari es di PT Sharp
Electronics Indonesia. Setelah dilakukan analisis pengendalian kualitas dengan diagram
kendali u, demerit, dan AHP demerit didapatkan hasil bahwa ketiga diagram kendali
menunjukkan adanya overdispersi, sehingga memerlukan analisis lebih lanjut dengan
menggunakan diagram kendali Laney u, Laney demerit, dan Laney demerit berbasis AHP.
Pada setiap diagram kendali menunjukkan adanya titik observasi out of control sehingga
proses produksi lemari es PT Sharp Electronics Indonesia tidak terkendali secara statistik.
Sementara itu, diagram kendali Laney demerit berbasis AHP merupakan diagram kendali
dengan sensitivitas paling tinggi dengan menunjukkan titik out of control paling banyak.
Kemudian pada analisis kapabilitas proses, menunjukkan nilai performance process kurang
dari satu sehingga proses tidak kapabel.
========================================================================================================================
Technological developments in Indonesia are very fast and this is accompanied by the
large number of electronic products used by the public. One of them is a refrigerator which
functions to cool food and drinks and has become an important electronic device for today's
society. Refrigerator production at PT Sharp Electronics Indonesia has two types, namely one
door and two doors, both types are domestic production with promising quality and model
innovation that continues to develop. However, monitoring of the production process carried
out at PT Sharp Electronics Indonesia is carried out manually and monitoring using control
charts has not been implemented. Therefore, quality control analysis is needed using AHP�based u, demerit and demerit control charts to maximize the refrigerator production process at
PT Sharp Electronics Indonesia. After carrying out quality control analysis using u, demerit,
and AHP demerit control diagrams, the results showed that the three control diagrams showed
overdispersion, thus requiring further analysis using AHP-based Laney u, Laney demerit, and
Laney demerit control charts. Each control diagram shows that there is an out of control
observation point so that the PT Sharp Electronics Indonesia refrigerator production process is
not statistically controlled. Meanwhile, the AHP-based Laney demerit control chart is the
control chart with the highest sensitivity by showing the most out of control points. Then in
the process capability analysis, it shows that the process performance value is less than one so
the process is not capable.
