Abstract
Pada sistem penyediaan air minum (PDAM), pengendalian kualitas air menjadi krusial untuk memastikan air yang disediakan memenuhi standar kesehatan dan lingkungan. Penelitian ini mengkaji penggunaan Peta Kendali Multivariate Exponentially Weighted Moving Variance (MEWMV) dan Multivariate Exponentially Weighted Moving Variance Average (MEWMA) dalam pengendalian kualitas air di PDAM Kota Surabaya. MEWMV diimplementasikan dengan parameter ω optimal sebesar 0.5 dan λ sebesar 0.9, sedangkan MEWMA menggunakan λ optimal sebesar 0,9. Data kualitas air yang digunakan meliputi kekeruhan, pH, sisa chlor, dan zat organik yang diukur dalam periode waktu tertentu. Analisis dilakukan terhadap data historis untuk menentukan batas kontrol yang sesuai dengan spesifikasi kualitas air. Hasil analisis menunjukkan bahwa proses produksi air di IPAM Ngagel I mampu mempertahankan kekeruhan dan pH dalam batas spesifikasi yang ditetapkan. Namun, terdapat tantangan dalam mempertahankan konsistensi produksi air dengan kadar sisa chlor dan zat organik yang sesuai. Penelitian ini memberikan kontribusi penting dalam pengembangan metode pengendalian kualitas air dengan pendekatan MEWMV dan MEWMA.
=========================================================== In a water supply system (PDAM), water quality control is crucial to ensure that the water provided meets health and environmental standards. This study examines the use of Multivariate Exponentially Weighted Moving Variance (MEWMV) and Multivariate Exponentially Weighted Moving Variance Average (MEWMA) Control Maps in water quality control at PDAM Surabaya City. MEWMV is implemented with optimal parameter ω of 0.5 and λ of 0.9, while MEWMA uses optimal λ of 0.9. The water quality data used includes turbidity, pH, residual chlorine, and organic matter measured over a period of time. Analyses were conducted on the historical data to determine the control limits in accordance with the water quality specifications. The results of the analysis showed that the water production process at IPAM Ngagel I was able to maintain turbidity and pH within the set specification limits. However, there are challenges in maintaining consistent water production with appropriate levels of residual chlorine and organic matter. This research makes an important contribution to the development of water quality control methods using the MEWMV and MEWMA approaches.
