Abstract

Air merupakan salah satu factor penting dalam penentuan kebutuhan umat manusia di bumi, keberadaan air sangat banyak dan sangat berlimpah di muka bumi, contohnya mata air, waduk, sungai, danau, hingga laut. Seperti yang kita ketahui bersama luas wilayah perairan di bumi lebih besar dari luas daratan yang ada, Sehingga masalah air merupakan masalah utama yang ada, baik masalah penyediaan air bersih, pencemaran air, serta masalah pencemaran dan penyaluran air. Supaya IPA dapat beroperasi dengan baik, maka diperlukan evaluasi terhadap IPA. Penelitian ini bertujuan untuk : 1) Mengetahui penggunaan tawas yang ada pada PDAM xyz; 2) Membandingkan kualitas air produksi yang dihasilkan dengan standar PERMENKES No. 492 tahun 2010; 3) Mengetahui bagaimana proses pengolahan air; data yang digunakan atau yang di dapat dari PDAM yaitu data penggunaan tawas dan melakukan pengecekan terhadap parameter fisika dan kimia, parameter fisika dan kimia yang digunakan meliputi kekeruhan, pH, suhu, warna dan bau. Menurut hasil yang di dapat parameter yang diuji telah memenuhi standar PERMENKES No. 492 tahun 2010. Proses pengolahan air yaitu, Intake, Clarifier yang terdiri dari beberapa proses, lalu ada reservoir. Sumber air yang digunakan pada instalasi pengolahan air yaitu menggunakan anak kali brantas, anak kali brantas sendiri termasuk golongan 2. Water is an important factor in determining the needs of mankind on earth, the existence of water is very much and very abundant on earth, for example springs, reservoirs, rivers, lakes, to the sea. As we all know, the area of waters on earth is larger than the existing land area, so that the water problem is the main problem, both the problem of clean water supply, water pollution, and the problem of water pollution and distribution. In order for Water Treatment Installations to operate properly, it is necessary to evaluate Water Treatment Installations. This study aims to: 1) Know the use of alum in PDAM Gresik; 2) Comparing the quality of production water produced with the PERMENKES No. standard. 2 in 2023; 3) Know how the process of water treatment; the data used or obtained from PDAM is data on the use of alum and checking the physical and chemical parameters, the physical and chemical parameters used include turbidity, pH, temperature, color and odor. According to the results obtained, the tested parameters met the PERMENKES No. standards. 2 of 2023. The water treatment process is Intake, Clarifier which consists of several processes, then there is a reservoir. The source of water used in the water treatment plant is using the Brantas River, the Brantas River itself is included in group 2.

Abstract

Due to its high cellulose content, Bintaro fruit and jackfruit peel can be used as activated carbon. The purpose of this study was to determine the activator and optimum contact time and determine the appropriate adsorption isotherm on activated carbon of Bintaro fruit and jackfruit peel in reducing Fe, Mn and Cu parameters. In this study, the sample water used well water in Surabaya City. The variations used in this study are activator variations and contact time. The activators used are HCl and H2SO4 for the contact time used are 30, 60, 90 and 120 minutes. From the results of the study, the optimum activator was HCl with a contact time of 120 minutes with the highest percentage removal of Fe content of 88.8% by jackfruit peel activated carbon. For Mn reduction, the optimum activator is H2SO4 with a contact time of 120 minutes on jackfruit peel activated carbon with the highest percentage removal of 89.2%. For Cu reduction, the most optimal activator is HCl with a contact time of 120 minutes on jackfruit peel activated carbon with the highest percentage removal of 90.9%. The type of adsorption isotherm in the reduction of Fe, Mn and Cu levels in this study as a whole follows the Freundlich isotherm equation.
