Abstract
PDAM Surya Sembada Kota Surabaya merupakan
perusahaan yang bekerja di bidang pengolahan air di Kota Surabaya.Sebagai acuan dari kualitas air, PDAM Surya Sembada
menggunakan Permenkes No. 492 Tahun 2010 sebagai pedoman
dalam melaksanakan pengendalian kualitas terhadap air produksi.Terdapat 24 variabel dalam kualitas air yang selama ini telah diawasidi PDAM Surya sembada Surabaya. Namun, untuk karakteristik utama kualitas air digunakan tiga buah variabel kekeruhan, KMnO4 , dan Sisa chlor. Pada pengendalian kualitas secara multivariat dapat
dilakukan dengan menggunakan peta kendali MEWMA dan MEWMV.
Peta kendali MEWMV digunakan untuk mengendalikan variabilitas proses, sedangkan peta kendali MEWMA digunakan untuk mengendalikan mean proses. Hasil yang didapat untuk variabilitas proses telah terkendali secara statistik dengan menggunakan pembobot optimum sebesar ω=0.3 dan λ=0.4, sedangkan untuk mean proses belum terkendali secara statistik dengan menggunakan nilai pembobot optimum λ sebesar 0.7. Hasil deteksi penyebab mean proses tidak terkendali adalah variabel KMnO4 dengan jumlah data out of control paling banyak. ============== PDAM Surya Sembada Kota Surabaya is the only company for water production in Surabaya. PDAM Surya Sembada Kota Surabaya has been using Permenkes no. 492 Year 2010 as a guideline in implementing quality control on water production. There are many variables in water quality that have been supervised at PDAM Surya in Surabaya. However, for the main characteristics of water quality used three variables of turbidity, KMnO4, and residual chlor. On
multivariate quality control can be done by using MEWMA and
MEWMV control chart. The MEWMV control chart is used to control process variability, while the MEWMA control chart is used to control the process mean. The results obtained for process variability were statistically controlled using the optimum weighting of ω = 0.3 and λ= 0.4, while for the process mean was not statistically controlled using the optimum weighted value λ of 0.7 with KMnO4 as the cause of
multivariat process out of control.
