ABSTRAK Hingga saat ini pencemaran air masih menjadi persoalan krusial di berbagai negara, khususnya di negara-negara berkembang termasuk Indonesia. Evaluasi tingkat pencemaran air secara berkala merupakan salah satu bentuk upaya dalam sistem pengelolaan sumberdaya air. Metode Indeks Pencemaran (IP) merupakan salah satu metode analisis kualitas air yang diaplikasikan di Indonesia. Metode ini merupakan perhitungan relatif antara hasil pengamatan terhadap baku mutu yang berlaku. Sebagai metode indeks komposit, IP terdiri atas indeks rata-rata dan indeks maksimum. Indeks maksimum dapat memberikan indikator unsur kontaminan utama penyebab penurunan kualitas air. Unsur utama dapat dihubungkan dengan sumber pencemar, apakah dari domestik maupun, non domestik (industri). Studi kasus dilakukan di hulu DAS Citarum (segmen Wangisagara-Nanjung) menggunakan data historikal tahun 2002 s.d. 2010. Hasil penelitian tersebut menunjukkan bahwa fecal coliform, sulfida, dan fenol merupakan tiga unsur utama penurunan kualitas Sungai Citarum. Fecal coliform adalah parameter tipikal dalam limbah domestik. Fenol adalah parameter tipikal dalam limbah industri. Sedangkan sulfida bisa berasal dari domestik maupun industri. Hasil penelitian menunjukkan telah terjadi diferensiasi polutan dari sumber domestik saja menjadi domestik dan non domestik setelah tahun 2005.

Generally physical and chemical methods are use in river water quality monitoring; currently biomarker is developed as alternative biomonitoring method. The aim of this study is to look at the probability using aquatic species in monitoring river water pollutants exposure. This study was done by using Hyposarcus pardalis as biomarker to analyze river water quality in Upstream Citarum River. Hyposarcus pardalis were taken along the river at five sampling point and look at the Cu and Zn concentration. Results from this study show that there was an indication that river water quality has been degrading along the river from upstream to downstream. Zn concentration in Hyposarcus pardalis were increasing as well as Cu concentration. The increase of Zn concentration in Hyposarcus pardalis indicating that the river was polluted by Zn. Secondary data and observation at sampling location shown that textile was the dominant industry which may contribute the Zn concentration in river as they received the effluent. Cu is use in metal coating process, as well as textile industry metal industries were identified at Majalaya, Bantar Panjang, Dayeuh Kolot and Katapang in Bandung-Indonesia. As a receiving water from many activities along the river, upstream Citarum River water quality become degrading as the increasing of heavy metal Zn and Cu concentration in Hyposarcus pardalis.

Through structured interviews and statistical analyses, this study investigated access to water and strategies of 1227 vulnerable households in Bandung, Indonesia. The use of mixed water sources, household water treatment, and home storage suggest low trust in improved sources, and compromised safety and reliability of water. While official statistics suggest a high level of access to improved water sources, full-time access to such sources is overestimated. Integration of user behavior into the new monitoring approach for the water supply sector in the post-2015 development framework is proposed.

The characteristics and composition of dissolved organic matter (DOM) and trihalomethane (THM) generation during water treatment are important for producing safe drinking water. However, little information is available on this topic within the context of Indonesia. This study aimed to investigate the efficiency of a conventional drinking water treatment plant (WTP) in removing DOM and chloroform forming potential (CHCl3FP), and evaluate surrogate parameters for CHCl3FP. Samples were taken during the rainy season and the dry season from raw water, after secondary treatment and after the rapid sand filter. DOM was characterized based on the A254, A355, SUVA, dissolved organic carbon (DOC), and fluorescence DOM (FDOM) parameters. The composition of the DOM was identified using the peak picking method. Overall, from raw to finished water, the WTP performed better in the rainy season with 55.96% reduction of DOC and 63.45% reduction of A355 as compared to the dry season with 53.27% reduction of DOC and 24.18% reduction of A355.The overall removal of humic and tryptophan compounds during the rainy season was 33.33% and 37.50%, respectively. In the dry season, humic compounds were reduced by 18.80%, while tryptophan increased threefold. A355 can serve as a surrogate parameter for CHCl3FP in raw water and water after secondary treatment, containing more humic-like compounds than tryptophan-like compounds.

This research focused on the speciation and distribution patterns of cadmium in surface sediment from Saguling Lake, which is located in the Upper Citarum River. Organic compounds and heavy metals from anthropogenic activities in the watershed have contaminated the river. Sample from the upper layer of the sediment from Saguling Lake were taken from 12 locations, representing the dry and the rainy seasons in the period 2015-2018. Sediment cadmium (Cd) classification was conducted through a sequential extraction technique to determine Cd’s bioavailability and its risk to the water environment. During the rainy season, the total Cd concentration in the upper layer of the sediment was higher than during the dry season. The average dry and rainy season concentrations were 11.12 ± 2.16 mg/kg and 14.82 ± 1.48 mg/kgm in the sampling locations, distributed differently with the following order of the largest to the smallest concentration: 10B > 1A > 4 > 3 > 2 > 1B > 10A > 7 > 9 > 5 > 6 > 8 for the dry season, and 4 > 1A > 1B > 2 > 7 > 5 > 9 > 3 > 6 > 10A > 8 > 10B for the rainy season. All sampling locations (>60%) showed Cd in the resistant fraction, indicating no significant anthropogenic input of Cd into the surface sediment but more geological input due to high erosion. The values of RAC, ICF, and GFC indicate that the Cd in the surface sediment can be categorized as low risk.

The objective of this study is to determine the sensitivity of Citarum river flow to climate change and land conversion. It will provide the flow information that required in the water resources sustainability. Saguling reservoir is one of the strategic reservoirs, which 75% water is coming from the inflow of Upper Citarum measured at Nanjung station. Climate variability was identified as rainfall variability. Sensitivity was calculated as the elasticity value of discharge using three-variate model of statistical approach. The landuse conversion was calculated used GIS at 1994 and 2004. The results showed that elasticity at the Nanjung station and Saguling station decreased from 1.59 and 1.02 to 0.68 and 0.62 respectively. The decreasing occurred in the before the dam was built period (1950-1980) to the after reservoirs operated period (1986-2008). This value indicates that: 1) Citarum river flow is more sensitive to rainfall variability that recorded at Nanjung station than Saguling station, 2) rainfall character is more difficult to predict. The landuse analysis shows that forest area decrease to ± 27% and built up area increased to ± 26%. Those implied a minimum rainfall reduction to± 8% and minimum flow to ± 46%. Those were caused by land conversion and describing that the vegetation have function to maintain the base flow for sustainable water resource infrastructure.

Fe(II) terlarut dapat bergabung dengan zat organik dan membentuk senyawa kompleks yang sulit untuk dihilangkan dengan aerasi biasa. Salah satu teknologi alternatif untuk menghilangkan besi tersebut adalah dengan Advanced Oxidation Processes (AOPs) yang dapat menghasilkan radikal hidroksil (OH"¢). OH radikal yang terbentuk mempunyai potensial oksidasi yang tinggi sehingga diharapkan mampu mengoksidasi senyawa besi kompleks zat organik. Penelitian ini bertujuan untuk mengetahui efisiensi penurunan besi menggunakan H2O2-UV, kinetika reaksi yang terjadi, dan melihat pengaruh masing-masing faktor serta interaksi setiap faktor terhadap reaksi oksidasi besi melalui uji statistik. Penelitian ini dilakukan secara batch dengan variasi konsentrasi besi total awal: 3, 5, dan 10 mg/l; Fe:H2O2 = 1:5, 1:8, dan 1:10 (mol/mol); dengan perlakuan menggunakan UV 3x10 watt dan tanpa UV. Hasil penelitian menunjukkan bahwa kombinasi H2O2-UV 3x10 watt memberikan efisiensi penurunan besi yang paling baik pada dosis Fe:H2O2 = 1:5, yaitu 99% dan H2O2 menghasilkan efisiensi paling baik pada dosis Fe:H2O2 = 1: 8, yaitu 84%. Semakin besar konsentrasi besi total awal semakin kecil persen penurunan besi. Tetapi tidak selamanya penambahan dosis H2O2 akan meningkatkan efisiensi. Sedangkan sinar UV memberikan pengaruh yang lebih besar terhadap oksidasi besi apabila dikombinasikan dengan H2O2. Reaksi oksidasi besi ini menghasilkan orde pertama-semu untuk penurunan besi kompleks zat organik dan konstanta laju reaksi semakin besar apabila oksidasi menggunakan H2O2-UV 3 x10 watt. Proses oksidasi dengan H2O2-UV 3x10 watt ini akan menghasilkan persen penurunan Fe-R sebesar 67% setelah diujikan pada air sumur di daerah Bandung.

White rot fungi Phanerochaete chrysosporium strain BKM-F-1767 are known to have extra cellular enzyme that able to degrade chlorolignin. Previous study showed that high delignification ability of the fungi is not supported by dehalogenase processes. This study is done by using rice straw as carbon source for chloroklorolignin degradation. The study is conducted in batch culture with straw concentration of 3.2 g/L and 0.3 g/L for chloroklorolignin. The straws are varies in form of powder and chips. The enzymes activity are identified in liquid, solid and SDS-PAGE. By using SDS-PAGE the enzymes identified are molecular weight 42 kD and 29 kD which is indicating the occurrence of Klorolignin peroxidase (LiP) and active endoglucanse in 11th day. Positive result from solid media showed that Phanerochaete chrysosporium has an ability to degrade high molecular chloroklorolignin through enzymatic mechanism resulting from secondary metabolism reaction in generating H2O2.INTISARIJamur Phanerochaete chrysosporium strain BKM-F-1767 diketahui memiliki enzim ekstraseluler yang mampu untuk mendegradasi senyawa khloroklorolignin. Studi terdahulu menunjukkan bahwa kemampuan delignifikasi yang tinggi oleh jamur ini tidak selalu didukung oleh proses dehalogenase. Selain itu, jamur sangat tergantung pada keberadaan glukosa sebagai co-substrat utama untuk pertumbuhan. Dengan penambahan jerami diharapkan konsentrasi glukosa dapat dikurangi karena keberadaan senyawa selulosa yang dapat dijadikan sumber karbon bagi jamur. Pada penelitian ini digunakan sistem kultur batch dengan variabel tetap yaitu jumlah jerami sebesar 3,2 g/L dan substrat yang digunakan yaitu klorolignin dengan konsentrasi 0,3 g/L. Variabel bebas yang digunakan adalah konsentrasi co-substrat glukosa dan tipe perlakuan jerami yang berbeda yaitu potongan (chips) dan serbuk. Aktivitas-aktivitas enzim ekstraseluler diuji melalui media padat, cair, dan SDS- PAGE. Percobaan dengan SDS-PAGE diperoleh enzim dengan berat molekul 42 kD dan 29 kD yang mengindikasikan adanya enzim LiP dan endoglucanase yang masih aktif hingga akhir hari ke-11. Hasil positif yang diperoleh pada media padat menunjukkan bahwa jamur Phanerochaete chrysosporium memiliki kemampuan untuk mendegradasi senyawa klorolignin berat molekul tinggi melalui mekanisme sistem enzimatik yang dihasilkan oleh reaksi metabolisme sekunder dalam sistem generasi H2O2.
