Abstract

PDAM Surya Sembada Surabaya merupakan perusahaan milik pemerintah Kota Surabaya yang bergerak dalam bidang pengolahan air sehingga kualitas air produksi PDAM Surya Sembada Surabaya harus selalu diperhatikan. Selain itu kualitas kebersihan air bersih dapat dilihat dari parameter fisika, kimia, mikrobiologi pada air. Jika terdapat perubahan karakteristik pada air maka kualitas air juga akan menurun. Oleh karena itu dilakukan penelitian mengenai pengendalian kualitas pada air produksi PDAM Surya Sembada Surabaya. Penelitian ini dilakukan menggunakan grafik kendali multivariat MEC. Grafik kendali MEC terbagi menjadi dua yaitu MEC1 dan MEC2. Variabel yang akan digunakan adalah turbidity, sisa Chlor, dan zat organik. Pada hasil penelitian yang telah dilakukan menggunakan grafik kendali MEC1 dan MEC2 didapatkan hasil bahwa proses produksi air produksi tidak terkendali secara statistik. Grafik kendali MEC1 yang diterapkan pada data penelitian ini lebih sensitif dari grafik MEC2 karena menghasilkan lebih banyak pengamatan yang out of control. Setelah dilakukan identifikasi, variabel zat organik adalah variabel yang berpengaruh paling besar terhadap terjadinya out of control. Jika dilihat dari kapabilitas prosesnya, proses produksi air produksi di PDAM Surya Sembada Surabaya IPAM Ngagel I tidak kapabel. Penelitian ini diharapkan dapat memberikan manfaat kepada perusahaan PDAM Surya Sembada Surabaya sebagai evaluasi proses produksi air.
====================================================================================================================
PDAM Surya Sembada Surabaya is a Surabaya Government company in the field of drinking water treatment. The vision of the company is to become a modern drinking water company. Therefore, the quality of water produced by PDAM Surya Sembada Surabaya must always be controled. Besides the quality of clean water can be seen from the parameters of physics, chemistry, microbiology, and also radioactivity in the water. Therefore, this research will be conducted on quality control in the water production of PDAM Surya Sembada Surabaya. This research will be carried out using a combine of multivariate control chart from MEWMA-MCUSUM called MEC control chart. The MEC control chart is divided into two, they are MEC1 and MEC2. Variabels that used are turbidity, residual chlorine, and organic substances. In the result of this research, monitoring process using the control chart MEC1 and MEC2 show that the water production process is not statistically controlled. The MEC1 control chart that more sensitive than the MEC2 chart because it produces more out of control observations. After the identification process, the organic subtances variable is the variable that has the biggest impact on the occurrence of out of control. In the capability analysis, the process of water production in PDAM Surya Sembada Surabaya IPAM Ngagel I is said to be not capable. This research is expected to provide benefits to the company of PDAM Surya Sembada Sura-baya as an evaluation of the water production process.
