Abstract

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.

Abstract

Since the middle of the 20th century, pesticide use has been a primary foundation of global agricultural development. However, the massive usage of pesticides can have detrimental impacts on human health and the environment, particularly in the aquatic ecosystem. This study determined the use of pesticides in the agricultural area of the Upper Citarum River Basin (UCRB); a crucial water resource on Java Island. A survey of 174 farmers was conducted in eight districts along the basin by using the random walk and quota sampling method. The questionnaire was designed to acquire data about the amount and types of pesticides used by farmers. Pre-survey was conducted to evaluate the feasibility of the questionnaire draft. The respondents’ answers were inputted into an equation to estimate the pesticide use per year. The survey results showed that 31 different pesticides were used for 21 types of crops. Profenofos and Mancozeb were the two most used pesticides, among all. The highest annual average used per hectare was reported for Chlorothalonil on tomato (32.2 kg/ha/year), followed by Mancozeb on corn (28.6 kg/ha/year), and Chlorpyrifos on chili (26.1 kg/ha/year). Overall, the pesticide use estimation in the study area is relatively high, with an annual average of 24.6 kg/ha/year. A comparison between prescribed and actual use on rice (representing more than 64% of the total surveyed area) showed that most pesticides are used in line with the prescriptions, but about a quarter is used in larger amounts than recommended. This comparison also revealed that some farmers use pesticides for rice that are not recommended for rice farming. In conclusion, the data presented in this study can be used to estimate pesticide emissions for environmental risk assessment and to support water quality monitoring, especially since public accessibility of pesticide information is commonly limited in Indonesia and other low- and middle-income countries.

Abstract

Reactive Black 5 (RB5) is one of the dyes used in textile industries in Indonesia. However, the high color content can interfere with the condition of water bodies if not treated. This waste treatment process is usually treated with biological treatment processes. Biological processing often used is the MBBR unit and activated sludge. This study aims to determine the RB5 dye’s bio-sorption efficiency using MBBR processing and activated sludge. MBBR processing and activated sludge consist of seeding, acclimatization, and running stages. This research was carried out using a real textile wastewater approach by adding 100 mg/L RB5 and adding 1000 mg/L starch solution. The processing results of the seeding stage indicate increasing in biomass. The acclimatization stage with 50% and 75% of wastewater indicates increased biomass and color removal. The RB5 color removal efficiency results in the MBBR unit and activated sludge show 41% and 84% values. The MBBR processing shows fluctuations each time where the desorption process occurs in the color removal. For this reason, the ozone pre-treatment process is conducted in the MBBR unit. The integrated pre-treatment with MBBR results show the same fluctuation as the previous processing with a color removal efficiency of 43% with a color removal efficiency of 43%.

Abstract

Solid waste management on Nusa Penida Island is one of the problems in tourism in Bali Province. To deal with this issue, the government has implemented various policies, where the policy that becomes an essential issue is the processing of energy waste. To support this, it is necessary to study the potential of waste characteristics on the island of Nusa Penida. This study aims to analyse the characteristics of waste on the island of Nusa Penida as an energy source based on the generation and composition of waste. Solid waste generation and composition were measured based on land and marine debris data. The total waste generation on land and marine debris can reach 6364.4 kg/day and 762.8 kg/day, respectively. The waste composition materials consist of masks, plastics, metals, and biodegradable organics with a value of 4.12%, 32.77%, 19.54%, and 43.57%, respectively. Therefore, the potential use of organic biodegradable as solid fuel can reach 51,933.8 MJ/day or 14,426 kWh/day. However, in the thermogravimetric analysis (TGA) test, the residue was 18.6%.

Abstract

Investment and operation of water infrastructure is expensive. In order to prevent the failure of investment and operation caused by unpredictable cost, cost estimation before the development of water infrastructure is very important. Theories and concept in water supply engineering show that environmental condition has an important role in determining cost variation of water infrastructure. This article explores to what extent environmental condition was considered in empirical cost studies. It reveals that environmental condition has not been considered comprehensively in empirical cost studies, especially cost estimation studies.Keywords: water infrastructure, cost estimation, environmental condition

Abstract

In this study, synthesis of TiO2 nanofiber-nanoparticle composite photocatalyst was carried out and its photocatalytic decolorization performance was investigated. TiO2 nanofibers were developed by electrospinning. The TiO2 nanoparticle films were prepared by dipping the glass substrates into a sol solution made by sol-gel method. The TiO2 nanofiber-nanoparticle composite was immobilized on glass plates and annealed at 500 °C. The effects of pH and catalyst loading were studied during a photocatalytic decolorization experiment using simulated dyeing wastewater containing Reactive Black 5 (RB5). The photocatalytic decolorization performance with 60 min of UV-irradiation time using the TiO2 nanofiber-nanoparticle composite was found to be higher (94.4%) than that of the TiO2 nanofibers (75.5%) and the TiO2 nanoparticle catalyst (74.1%). An alkaline condition and high catalyst loading were found to be preferable to achieve optimum photocatalytic decolorization of Reactive Black 5 (RB5). The TiO2 nanofiber-nanoparticle composite could be recovered after reusing multiple times through re-annealing at a high temperature. TiO2 nanofibers based on a composite catalyst that is strongly immobilized on glass plates enlarges the prospect of the photocatalytic method as a compact, practical and effective advanced treatment process for effluents from textile wastewater.

Abstract

The ability of fly ash to adsorp Cu(II) ions from two different coal combustion systems was studied. Optimum removal was found at pH 5, contact time 30 minutes and 60 minutes for Fly Ash 1 and Fly Ash 2, respectively, and dosage 10 g/l. The difference in adsorption capacity between both fly ashes may be due to their carbon fraction and CaO content. The removal of Cu (II) ions was caused by both adsorption and/or precipitation. Precipitation is enhanced by lowering the carbon fraction and increasing the CaO content. The adsorption isotherm showed that the Langmuir model fitted well to the experimental data of both fly ashes. A thermodynamic study was conducted at three different temperatures: 25 °C, 45 °C, and 60 °C. The adsorption processes were spontaneous and endothermic and were more favorable at higher temperature.

Abstract

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.

Abstract

Dalam penelitian ini dipelajari mekanisme degradasi fotokatalitik air limbah tekstil simulasi mengandung zat warna azo Acid Red 4 (AR4) menggunakan katalis mikropartikel TiO2.Tujuan penelitian ini adalah untuk memperoleh gambaran tahapan degradasi fotokatalitik berupa pemutusan struktur molekul zat warna AR4. Mekanisme degradasi dianalisis melalui pengukuran terhadap TOC, pH dan spektra absorbansi warna seiring interval waktu proses fotokatalitik, dilanjutkan dengan identifikasi produk degradasi menggunakan GC-MS. Setelah irradiasi UV selama 5 jam terjadi penurunan TOC hingga 90%, mengindikasikan terjadinya proses mineralisasi terhadap AR4. Penurunan puncak spektra absorbansi pada rentang panjang gelombang 300-320 nm dan 490-510 nm menunjukkan adanya pemutusan struktur molekul AR4 menjadi senyawa yang lebih sederhana, terdiri dari pemutusan kromofor warna (ikatan azo) dan pemutusan cincin-cincin senyawa amina aromatik (cincin benzen dan naftalen). Lebih lanjut, identifikasi produk degradasi dengan GC-MS seiring interval waktu proses fotokatalitik menunjukkan bahwa proses degradasi diawali dengan tahapan pemutusan molekul zat warna menjadi senyawa antara dilanjutkan dengan tahapan destruksi senyawa antara menjadi asam-asam organik sederhana yang mendekati tingkat mineralisasi.
