"This book presents the basic aspects of water quality, emphasizing physical, chemical, and biological factors.  The study of water quality draws information from a variety of disciplines including chemistry, biology, mathematics, physics, engineering, and resource management.
University training in water quality is often limited to specialized courses in engineering, ecology, and fisheries curricula. This book also offers a basic understanding of water quality to professionals who are not formally trained in the subject.
The revised second edition updates and expands the discussion, and incorporates additional figures and illustrative problems. Improvements include a new chapter on basic chemistry, a more comprehensive chapter on hydrology, and an updated chapter on regulations and standards.
Because it employs only first-year college-level chemistry and very basic physics, the book is well-suited as the foundation for a general introductory course in water quality. It is equally useful as a guide for self-study and an in-depth resource for general readers.

"Terlepas dari usaha untuk meningkatkan akses berkelanjutan ke air minum yang aman, ratusan juta orang masih bergantung pada sumber air unimproved. Untuk meningkatkan kualitas air minum, berbagai pengolahan air rumah tangga dan metode penyimpanan aman telah dikembangkan dan dikenalkan sebagai intervensi alternatif. Namun, informasi mengenai kualitas air minum dan prevalensi praktik pengolahan air minum rumah tangga, terutama dari perspektif dan tingkat kepuasan masyarakat masih sangat minim. Penelitian ini dilakukan untuk mengkaji kualitas air minum di Kota Metro, menganalisis persepsi dan tingkat kepuasan masyarakat terhadap air minumnya, serta menganalisis hubungan antar variabel. Survei lapangan dan observasi (n=281), serta pengambilan sampel air minum (n=79) dilakukan pada rumah tangga di Kota Metro. Pengujian kualitas sampel air minum dilakukan untuk parameter kekeruhan, Total Dissolved Solid (TDS), dan E. Coli. Pada uji kekeruhan dengan turbidimeter, ditemukan 4% sampel (n=79) memiliki kekeruhan yang melebihi baku mutu dengan rata-rata 1,3 NTU sedangkan uji TDS dengan multi-parameter probe menemukan bahwa tidak terdapat sampel yang melebihi baku mutu dengan rata-rata 82,46 mg/l. Tingkat risiko E. Coli pada air minum E. Coli beragam dengan rata-rata melebihi baku mutu Permenkes No. 492 Tahun 2010 yaitu sebesar 43,14 MPN/100 ml. Berdasarkan uji analisis korelasi Spearman Rank’s, ditemukan bahwa seluruh variabel memiliki korelasi yang signifikan antara persepsi serta tingkat kepuasan dengan kualitas air minum. Nilai korelasi Spearman dari tiap hubungan berada dalam rentang 0,232 hingga 0,276 sehingga seluruh variabel berkorelasi lemah dengan arah hubungan positif dan menunjukkan bahwa terdapat hubungan berkekuatan lemah antara persepsi dan tingkat kepuasan masyarakat dengan kualitas air minum dimana semakin baik kualitas air minum, persepsi dan tingkat kepuasan masyarakat juga semakin baik. Adapun rekomendasi yang perlu dilakukan dari studi ini ialah melakukan pemantauan dan pemeliharaan rutin pada sumber air minum mulai dari air tanah hingga depot air minum isi ulang dimana ditemukan kontaminasi E. Coli dengan risiko tinggi dan mengkomunikasikannya, mengadakan kampanye yang merekomendasi pengolahan air minum rumah tangga dan perawatan wadah penyimpanan air minum sesuai rekomendasi STBM pilar ke-3. 

Despite efforts to improve sustainable access to safe drinking water, hundreds of millions of people still depend on unimproved water sources. To improve drinking water quality, various household water treatment and safe storage methods have been developed and introduced as alternative interventions. However, information on drinking water quality and the prevalence of household drinking water treatment practices, especially from the perspective and level of community satisfaction, is still very minimal. This study was conducted to examine the quality of drinking water in Metro City, analyze the perception and level of community satisfaction with drinking water, and analyze the relationship between variables. Field surveys and observations (n=281), as well as drinking water sampling (n=79) were conducted on households in Metro City. Testing the quality of drinking water samples was carried out for the parameters of turbidity, TDS, and E. Coli. In the turbidity test with a turbidimeter, it was found that 4% of the samples (n=79) had turbidity that exceeded the quality standard with an average of 1,3 NTU, while the TDS test with a multi-parameter probe found that there were no samples that exceeded the quality standard with an average of 82,46 mg/l. The level of risk of E. Coli in drinking water of E. Coli varies with the average exceeding the quality standard of Permenkes No. 492 of 2010 which is 43,14 MPN/100 ml. Based on the Spearman Rank's correlation analysis test, it was found that all variables had a significant correlation between perceptions and levels of satisfaction with drinking water quality. The Spearman correlation value of each relationship is in the range of 0.232 to 0.276 so that all variables are weakly correlated with the direction of the positive relationship and indicate that there is a weak relationship between perceptions and levels of community satisfaction with drinking water quality where the better the quality of drinking water, perceptions and levels of community satisfaction also getting better The recommendations that need to be carried out from this study are carry out routine monitoring and maintenance on drinking water sources ranging from ground water to refill drinking water depots where high-risk E. Coli contamination is found and communicate it, conduct campaigns recommending household drinking water treatment and maintenance of drinking water storage containers according to the recommendations of the STBM-3rd pillar."

"Keseimbangan oksigen terlarut dipengaruhi oleh produksi dan pemanfaatan oksigen. Defisit oksigen terjadi apabila kebutuhan oksigen lebih besar dibandingkan ketersediaan oksigen. Salah satu solusi dalam mencegah dan mengatasi defisit oksigen pada perairan adalah dengan aerasi menggunakan aerator kincir air. Penelitian ini bertujuan untuk menganalisis perubahan parameter oksigen terlarut, kebutuhan oksigen kimiawi, sulfat, nitrat, dan amonia akibat aerasi kincir air serta jangkauan distribusi optimal setiap parameter dalam arah lateral – vertikal. Pengambilan sampel dilakukan pada enam titik berbeda dengan lima variasi waktu di Danau Mahoni Kampus UI Depok. Analisis dilakukan dengan uji t berpasangan, rancangan acak kelompok, uji BNT, dan analisis persentase efisiensi. Pemetaan distribusi parameter menggunakan aplikasi Surfer. Aerasi kincir air meningkatkan konsentrasi oksigen terlarut pada titik sampling hingga mencapai 105% pada pengoperasian selama 4 jam. Aerasi kincir air mampu menurunkan konsentrasi amonia dan COD serta meningkatkan konsentrasi nitrat. Aerasi kincir air tidak memberikan pengaruh yang signifikan terhadap perubahan konsentrasi sulfat. Aerator kincir air mampu mendistribusikan perubahan parameter oksigen terlarut, amonia, kebutuhan oksigen kimiawi, dan nitrat hingga jarak optimal arah lateral 4,5 m dan kedalaman 0,8 m dari permukaan air.

Dissolved oxygen balance is affected by the production and utilization of oxygen. An oxygen deficit occurs when the oxygen demand is greater than the availability of oxygen. One solution in preventing and overcoming the oxygen deficit in the waters is aeration using paddle wheel aerator. This study aims to analyze changes in dissolved oxygen, chemical oxygen demand, sulfate, nitrate, and ammonia parameters due to paddle wheel aeration and the optimal distribution of each parameter in the lateral – vertical direction. Sampling was carried out at 6 different points with 5-time variations in Lake Mahoni, UI, Depok. Statistical analysis was performed by paired t-test, randomized block design, LSD test, percentage efficiency analysis, and distribution mapping. Aeration of the paddle wheel increases the dissolved oxygen concentration in the sampling point up to 105% at 4 hours of operation. Aeration of the paddle wheel reduces the concentration of ammonia and COD and increases the concentration of nitrate while does not have a significant effect on changes in sulfate concentration. Paddle wheel aeration can affect the concentration of dissolved oxygen, chemical oxygen demand, ammonia, and nitrate up to an optimal distance of 4.5 m laterally and at a depth of 0.8 m vertically."

"Telah dilakukan penelitian mengenai penilaian kualitas air secara biologis menggunakan bioindikator makrozoobentos di Situ Agathis dan Situ Salam Universitas Indonesia, Depok pada bulan Februari 2020 yang mewakili musim hujan. Situ Agathis dan Situ Salam merupakan dua situ yang secara berturut-turut merupakan awal dan akhir dari aliran air di situ KAMPUS UI, Depok. Penelitian bertujuan untuk membandingkan kualitas air dengan menggunakan makrozoobentos sebagai bioindikator dengan Family Biotic Index (FBI) dan mengkaji penggunaan indeks keanekaragaman Shannon Wiener dan indeks dominansi Simpson di Situ Agathis dan Situ Salam Universitas Indonesia, Depok. Pengukuran parameter lingkungan fisik-kimia juga telah dilakukan seperti suhu, turbiditas, arus, TSS, TDS, pH, DO, BOD, fosfat dan nitrat. Berdasarkan hasil yang diperoleh, kualitas air di Situ Agathis termasuk kategori sangat buruk dengan nilai FBI berkisar 7,69—9,47 dan Situ Salam tergolong perairan agak buruk dengan nilai FBI sekitar 6,00—6,41. Indeks keanekaragaman di kedua situ tergolong rendah dengan nilai <2,302 dan nilai indeks dominansi <0,5 yang artinya tidak ada jenis makrozoobentos yang mendominansi walaupun beberapa famili ditemukan dalam jumlah individu yang banyak. Berdasarkan analisis data yang telah dilakukan dengan uji statistik Mann Whitney, terdapat perbedaan kualitas air di Situ Agathis dan Situ Salam Universitas Indonesia, Depok. Kualitas air di Situ Salam cenderung lebih baik dibandingkan di Situ Agathis karena adanya sistem cascade pond. Berdasarkan hasil pengukuran parameter fisik-kimia yang telah dilakukan, Situ Agathis dan Situ Salam tergolong dalam perairan yang masih dapat ditoleransi oleh organisme makrozoobentos.

Research on biological water quality assessment using macrozoobenthos in Situ Agathis and Situ Salam Universitas Indonesia, Depok was conducted on February 2020 which represents the rainy season. The study aimed to compare water quality using macrozoobenthos as bioindicator with the Family Biotic Index and to examine the Shannon Wiener diversity index and the Simpson dominance index in Situ Agathis and Situ Salam Universitas Indonesia, Depok. The measurement of physical and chemical environmental parameters such as temperature, turbidity, flow rate, TSS, TDS, pH, DO, BOD, phosphate and nitrate have also been carried out. Based on the results obtained, the water quality in Situ Agathis was classified as very poor with an average FBI score that ranged between 7.69—9.47 and Situ Salam was classified fairly poor with an average FBI score that ranged between 6.00—6.41. The diversity index in the two locations was classified as low diversity with the score <2.302 while the dominance index score is <0.5 which means there is no dominance even though some families are found in large number of individuals. Based on data analysis that has been carried out with the Mann Whitney statistical test, there are differences in water quality in Situ Agathis and Situ Salam Universitas Indonesia, Depok. The water quality of Situ Salam tends to be better than Situ Agathis due to a cascade pond system. Based on the results of the measurements of physical and chemical environmental parameters that have been carried out, Situ Agathis and Situ Salam are classified as waters that can be tolerated by macrozoobenthos organisms."

"ABSTRAK
Kualitas air permukaan di Kota Jakarta rata-rata sudah memasuki status tercemar berat. Dalam upaya mengurangi beban pengolahan IPAM, dibutuhkan proses pre-treatment untuk menyisihkan parameter seperti bahan organik, ammonia, warna, rasa, dan bau. Pengolahan ini umumnya menggunakan proses kimia dan fisik, seperti klorinasi dan karbon aktif yang menghasilkan produk sampingan yang berbahaya. MBBR merupakan salah satu solusi yang dikembangkan untuk mengurangi kadar nutrien dan organik pada air baku. Penelitian ini bertujuan untuk meningkatkan kualitas air baku, dengan menyisihkan parameter NH3-N, COD, Fosfat, TSS sebelum masuk ke pengolahan konvensional, dengan total kapasitas reaktor eksperimental sebesar 6 L. Kinerja reaktor dinilai berdasarkan efisiensi penyisihan parameter dengan variasi waktu tinggal 1 jam, 1,5 jam, 2 jam . Reaktor dioperasikan dengan menggunakan media Kaldness K1 dan suplai oksigen sebesar 7 L/menit. Waktu tinggal optimal yang dicapai adalah 1,5 jam dengan kemampuan penyisihan parameter NH3-N, COD, TP, TSS berturut-turut sebesar 54,3 0,28; 51,8 0,2; 52,6 0,19; dan 77,7 0,14. Berdasarkan dari waktu tinggal optimal tersebut, diketahui kinetika laju penyisihan ammonia pada MBBR berlangsung pada orde nol, dengan laju penyisihan sebesar 0,0056 g/m2.hari. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi kontaminan organik yang diolah, maka semakin tinggi pula efisiensi MBBR. Selain dari peningkatan mutu badan air, proses pre-treatment dengan menggunakan MBBR dapat mengurangi penggunaan dosis koagulan 50 mg/L menjadi 9 mg/L, untuk menurunkan kekeruhan air baku dari 135 NTU hingga 7,69 NTU sebelum memasuki unit koagulasi-flokulasi.

ABSTRACT
The quality of surface water in Jakarta is on a serious polluted status. In order to reduce the IPAM processing load, a pre treatment process is needed to eliminate parameters such as organic matter, ammonia, color, tase, and odor. This treatment generally uses chemical and physical processes, such as chlorination and activated carbon that produce harmful byproducts. MBBR is one of the solutions developed to reduce the nutrient and organic levels in raw water. This study aims to improve the quality of raw water, by reducing the concentration of COD, NH3 N, Phosphate, and TSS before entering the conventional process, with total experimental reactor capacity of 6 L. Reactor performance is assessed based on parameter removal efficiency with variation of residence time 1 hour, 1,5 hours, 2 hours . The reactor is operated by using Kaldness K1 as the medium and oxygen supply of 7 L min. The optimum residence time is 1,5 hours with the ability to remove COD, NH3 N, Phosphate, TSS 51,8 0,2 54,3 0,28 52,6 0,19 and 77,7 0,14 respectively. Based on the optimum residence time, the kinetics of the ammonia removal rate in MBBR takes place at zero order, with a rate constant removal of 0,0056 g m2.day. The results showed that the higher concentration of ammonia, and organic contaminants treated, the higher the efficiency of MBBR. Apart from water quality improvement, pre treatment process using MBBR can reduce coagulant dose from 50 mg L to 9 mg L, to decrease raw water turbidity from 135 NTU to 7,69 NTU before entering the coagulation flocculation unit.
