Abstract

Increase in science and technology development today has spurred environmental pollution in water, soil and air. Water pollution caused by the impact of industrial development must be controlled as quickly as possible. The study aimed to investigate the effect of Eichhornia crassipes plants at given metal concentrations. The Eichhornia crassipes plant was used as an observation material with varying concentrations of metal (Cr, Hg, and Pb). The method used in this study was Randomised Block Design (RBD) and continued with Duncan's Multiple Range Test analysis, or better known as the DMRT test. The study observations showed that the increase in Eichhornia crassipes seedlings was 3cm, 2cm and 2cm, respectively with the recorded concentrations of 20%, 40%, 60%, and 80%. Meanwhile, the leachate concentrations of 20%, 40%, 60%, and 80% could also increase the roots of Eichhornia crassipes plants by 3.5cm, 1.5cm and 1cm, respectively. However, the leaf growth of Eichhornia crassipes plants at concentrations of 20% and 40% recorded as much as three and two leaves only. Additionally, it can be noted that at leachate concentrations of 20% and 40%, there was an increase in the number of Eichhornia crassipes leaf petals during observation. Overall results showed that low concentrations could increase the Eichhornia crassipes plants. This was evident in the statistical test analysis, where the leachate concentration in the Eichhornia crassipes plant affected the overall test results.

Abstract

Abstract: TPA is the final location of the urban waste processing process by hoarding waste in landfills. The decomposition of waste and exposure to rainwater in landfills will produce a concentrated liquid, leachate. The presence of heavy metals at certain concentrations will turn toxic to aquatic ecosystems. In addition, high COD levels indicate the presence of large amounts of organic pollutants. One alternative to removing these contaminants is by using the adsorption method. In particular, this study aimed to determine the characteristics of activated carbon and the best dose variation in reducing pollutants in leachate. The analysis results of the characteristics of activated carbon in PET plastic waste are 2.2% moisture content, 2.6% ash content, 62.2% volatile matter content, and 33% bound carbon content. The water and ash content values complied with SNI 06-3730-1995, but for volatile matter content and bound carbon content, they did not comply with SNI 06-3730-1995. The best dose in reducing levels of heavy metals Fe and COD was at a 15-gram dose with a final value of Fe of 0.106 mg/L with an efficiency of 96.4% and COD of 3404 mg/L with an efficiency of 36.7%. Overall, the Fe metal content for all cases tested met the RI Minister of Health Regulation Number 32 of 2017. However, the COD level had not yet reached the quality standard of the Minister of Environment and Forestry Regulation Number 59 of 2016. Keywords: Adsorption, polyethylene terephthalate and characteristics.

Abstract

This study aims to evaluate the effectiveness of phytoremediation using plants in reducing chromium (Cr) levels and modifying pH in batik wastewater. The research was conducted using three experimental tanks: Control Tank (without plants), Tank 1 (with 8 plants) and Tank 2 (with 16 plants). The results showed that in the control tank the pH fluctuated and reached 8.1 on the 9th day, while in tank 1 and tank 2 the pH was more controlled with peak values of 7.9 and 8.2 respectively. The most significant reduction in chromium levels occurred in tank 2, with treatment efficacy reaching 70% on day 9, compared to 45% in tank 1 and 10.5% in the control tank. These results indicate that phytoremediation with more plants can significantly improve the treatment efficiency of batik wastewater, making it a potential and environmentally friendly method for industrial wastewater treatment. The phytoremediation method was carried out by observing variations in the number of plants using 3 reactor tanks. The first tank was a control tank, the second tank (BR2) contained 8 plants and the third tank (BR3) contained 16 plants. Samples were taken on days 3, 6 and 9. The results showed that the highest effectiveness in reducing total chromium (Cr) levels occurred in the third tank (BR3) on day 9, with a reduction of 70%.

Abstract

In an effort to utilise organic waste that also has high economic value, a promising technology for processing organic waste is bioconversion using Black Soldier Fly (BSF). This research aims to determine the effect of variation in feeding rate on the nutritional content of BSF larvae, the quality of BSF larvae residue and the waste reduction index in the ITERA food waste organic waste decomposition process. The results of the research and data analysis tests show that the residue of BSF larvae does not meet the SNI 19-7030-2004 organic fertiliser quality standards in terms of phosphorus content, but the elements P, K and C/N ratio still meet the standards. Analysis of the proximate content of BSF larvae showed that the highest fat content was 0.8529 in reactor B; for the highest protein content was 12.7204 in reactor A and the highest water content was 64.1010 in reactor C. Calculation results of the waste reduction index reached the highest value of 5.94 grams per day.

Abstract

Leachate is a liquid waste formed due to water seepage into waste piles containing high concentrations of organic and inorganic compounds that have the potential to pollute the environment. This study aims to evaluate the effectiveness of Azolla microphylla plants in reducing leachate pollutant parameters from the Blang Bintang TPA through the phytoremediation method. Variations of treatments include plant masses of 300 and 400 grams and residence times of 7 and 14 days. The parameters analyzed include Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), and Biochemical Oxygen Demand (BOD). The results showed that the best treatment was obtained at a plant mass of 400 grams with a retention time of 14 days, with the effectiveness of reducing COD by 22.95% (from 758 mg/L to 584 mg/L), TSS by 60.80% (from 523 mg/L to 205 mg/L), and BOD by 22.40% (from 424 mg/L to 329 mg/L). Although it has not met the leachate quality standards based on Permen LHK No. 59 of 2016, the use of Azolla microphylla shows potential as an environmentally friendly phytoremediation agent. It can be further developed as part of a sustainable leachate treatment system.

Abstract

Sungai Langka Village has a communal Wastewater Treatment Plant (WWTP) building, but the treated effluent still does not accordance the quality standards set by the Regulation of the Minister of Environment and Forestry Number 68 of 2016 concerning Domestic Wastewater Quality Standards. Phytoremediation was chosen as an environmentally friendly and easily applicable method. The selection of Myriophyllum aquaticum was due to its phytodegradation ability in breaking down organic and inorganic substances, as well as its abundance of bacteria that can absorb nutrients in the wastewater. This study used four reactors: Reactor A1 (control), Reactor A2 (phytoremediation), Reactor A3 (aeration), and Reactor A4 (phytoremediation and aeration). The results of this study showed that over time, the efficiency in reducing the ammonia parameter increased, with the following efficiencies recorded on day 15: Reactor A1 at 98.95%, Reactor A2 at 98.59%, Reactor A3 at 98.90%, and Reactor A4 at 98.15%. The results of statistical testing using multiple linear regression showed that the efficiency of ammonia parameter reduction was significantly affected by time variation, whereas the addition of aeration did not have a significant effect.

Abstract

The Sungai Langka Village area lacks drainage and has elevated roads, causing water to run off during rainfall and onto the roads and into people's yards. In these conditions, efforts will be made to utilise water runoff as an alternative water source. This study aims to determine the effect of infiltration in the application of biopori infiltration pit technology. This research was conducted using a quantitative approach. The data were processed using the Horton method and analysed descriptively. Infiltration data was collected in situ in the field. The data compared the infiltration rate before and after the application of biopori infiltration pits. The results showed that the infiltration rate was constant at 46 cm/hour, 44 cm/hour, 32 cm/hour, 36 cm/hour and 32 cm/hour before the application of biopori infiltration pits. Meanwhile, the infiltration rates after the application of biopore infiltration pits were 110 cm/hour, 78 cm/hour, 70 cm/hour, 104 cm/hour and 138 cm/hour. The aim of the study was to determine how increasing infiltration rates can reduce water runoff and increase groundwater reserves.
