ANALISA KAPABILITAS PROSES PRODUKSI AIR PDAM SURYA SEMBADA SURABAYA

ABSTRAK

Dalam memproduksi air bersih PDAM Surya Sembada kota Surabaya bukan hanya perlu memperhatikan pengendalian kualitas mutu secara kimia maupun biologi tetapi juga harus menganalisa secara statistik. Ada 3 macam karakteristik yang menjadi pertimbangan khusus di PDAM Surabaya untuk air produksi yaitu TSS dalam skala gl Sisa Chlor dalam skala ppm KekeruhanTurbidity dalam skala NTU. Untuk mengetahui seberapa besar kemampuan proses produksi air PDAM Surya Sembada kota Surabaya perlu dilakukan penghitungan kapabilitas prosesnya secara multivariate. Akan tetapi sebelum dihitung kapabilitas prosesnya maka perlu dibuat terlebih dahulu Peta Kendali Multivariate T2 Hotelling untuk mengetahui apakah proses sudah terkendali atau belum. Perlu dicari juga hal hal yang menyebabkan proses diluar kendali. Hal ini dapat dilakukan dengan membuat diagram Ishikawa. Tujuan pembuatan diagram Ishikawa adalah agar jika terjadi pengamatan pengamatan yang diluar kendali dapat dihilangkan. Setelah dilakukan pengamatan maka diketahui bahwa semua hasil pengujian memenuhi standar spesifikasi yang diinginkan. Akan tetapi setelah diuji secara statistik ternyata masih terdapat proses-proses yang diluar kendali. Setelah proses-proses yang diluar kendali dihilangkan dengan mengasumsikan diketahui penyebabnya maka diperoleh indeks kapabilitas proses multivariate pengolahan air bersih di IPAL Ngagel 2 PDAM Surya Sembada Surabaya 215. Harga MCp yang lebih besar dari satu ini menunjukkan bahwa proses pengolahan air bersih di IPAL Ngagel 2 sudah kapabel.


ABSTRACT

While product fresh water PDAM Surabaya Surya Sembada has to control not only the quality of chemical and biological quality but also to be analyzed statistically. There are 3 kinds of characteristics into consideration in Surabaya PDAM water production which is TSS in the scale g l Chlor waste ppm scale and Turbidity NTU scale. To find out how much process capability of water production in PDAM Surya Sembada Surabaya it needs calculation to be done in the multivariate. However before calculating process capability it needs to be made in advance Multivariate Hotelling T2 control chart to determine whether the process is under control or not. It also needs to look for things that may cause the process out of control. This can be done by making the Ishikawa diagram. The purpose of making Ishikawa diagram is that in case of observations that are beyond the control it can be eliminated. After the observation it is known that all the test results meet the standards desired specifications. However after statistically tested turns out there are some processes that out of control. Once the processes are beyond the control eliminated by assuming a known cause then obtained a multivariate process capability index of water treatment at the IPAL Ngagel 2 PDAM Surabaya Surya Sembada 2.15. MCP price greater than one indicates that
