PENGENDALIAN KUALITAS MULTIVARIATE DAN KEMAMPUAN PROSES PRODUKSI GELAS BOLA LAMPU DI MESIN RIBBON

ABSTRAK

PT Litechindo Utama adalah perusahaan yang memproduksi gelas yang digunakan untuk bola lampu maupun tube. Salah satu produk yang jumlah produksinya besar ialah Ribbon Bulb tipe PS-60. Selama ini pengendalian kualitas yang dilakukan hanya untuk satu karakteristik kualitas secara individual padahal seharusnya dikendalikan secara bersama-sama. Oleh karena itu perlu diimplementasikan di perusahaan tersebut metode Pengendalian Kualitas Multivariate. Untuk mengimplementasikan Pengendalian Kualitas Multivariate maka data karakteristik kualitas yang diambil adalah Neckthickness Sidethickness dan Topthickness hari Senin-Jumat. Faktor hari dan shift juga diteliti apakah memberikan kontribusi terhadap terjadinya cacat. Faktor penyebab tidak terkendalinya proses produksi dianalisa dengan peta kendali Multivariate sedangkan kemampuan proses dianalisa dari indeks kemampuan proses. Dari penelitian ini dapat disimpulkan bahwa faktor hari mempunyai pengaruh yang signifikan terhadap cacat yang terjadi pada proses produksi Ribbon Bulb tipe PS- 60 sedangkan untuk faktor shift tidak berpengaruh terhadap cacat yang terjadi pada proses produksi Ribbon Bulb tipe PS-60. Analisa kemampuan proses menunjukkan bahwa jika ditinjau dari karakteristik kualitas Neckthickness Sidethickness dan Topthickness proses belum mampu sedang dari karakteristik kualitas Topthickness proses sudah mampu.


ABSTRACT

PT. LITECHINDO UTAMA SURABAYA is a company which produces glass for light bulb and tube. One of its products which is very big in the number of production is Ribbon Bulb in the type of PS-60. So far the quality control undertaken is just for one quality characteristic individually actually it should be controlled all together. Therefore it is important to implement Multivariate Quality Control in that company. To implement the Multivariate Quality Control the quality characteristics data taken are Neck thickness Side thickness and Top thickness on Monday to Friday. Day and shift factors are also examined whether or not they contribute to the creation of any defects. Factors that cause the uncontrolled production process were analyzed by using Multivariate Control Chart while process capability was analyzed through Process Capability Index. From this research it can be concluded that day factor has a significant impact towards defects occur in the production process of Ribbon Bulb Glass type PS-60. While shift factor doesnt have any effect on the occurring of defects in the production process of Ribbon Bulb type PS-60. Process capability shows that in the quality characteristics of Neck thickness and Side thickness processes both are still incapable while in the quality characteristic of Top thickness it has been capable.
