Teknologi pengolahan air limbah khususnya untuk mengurangi konsentrasi amonia telah banyak dikembangkan, baik teknologi pengolahan secara biologi maupun kimia. Masalah teknologi tersebut pada umumnya membutuhkan biaya yang tinggi yang tidak sejalan dengan konsep keberlanjutan, apalagi menghasilkan limbah limbah B3 sebagai produk sampingannya. Untuk itu diperlukan alternatif rekayasa teknologi yang lebih berkelanjutan. Penelitian ini bertujuan untuk mengetahui potensi penggunaan eco-enzyme untuk mengurangi konsentrasi amonia dalam air limbah, sebagai alternatif teknologi rekayasa berkelanjutan. Hal ini dimungkinkan mengingat eco-enzyme terbuat dari air, bahan organik, dan gula merah atau molase , yang berarti semua bahan tidak mengandung bahan kimia dan residu berbahaya. Apalagi bahan organik yang digunakan bisa berasal dari sampah organik. Metode penelitian adalah eksperimen skala laboratorium pada sampel air buatan, menggunakan eco-enzyme yang terbuat dari kulit dan buah nanas yang telah difermentasi selama 6 bulan dengan hasil pH = 3,36 dan tidak terdeteksinya adanya amonia. Pada sampel air dengan konsentrasi amonia awal sebesar 34,5 mg/L, hasil penurunan konsentrasi amonia masing-masing sebesar 6,7%, 12,8%, 15,3% dan 25,2% pada pemberian eco-enzyme secara berturut-turut dengan konsentrasi 2%, 6%, 8% dan 10%. Pada data konsentrasi amonia yang mengalami penurunan dibandingkan dengan nilai awal, dilakukan analisis uji-t statistik menunjukkan nilai P (T<=t, two tail) sebesar 0,047 < 0,05, sehingga nilai penurunan tersebut signifikan karena kedua data tersebut berbeda nyata. Dapat disimpulkan bahwa penurunan konsentrasi amonia meningkat dengan meningkatnya konsentrasi eco-enzyme yang diberikan pada sampel air dengan linieritas 97.3 %.

Hazardous waste products and trash disposal methods are vital to society. Over the last few decades, the production of hazardous waste has increased in tandem with population growth, industrialization, increasing urbanization. The constantly increasing industry sector has resulted in the creation of a massive volume of hazardous waste. As a result, enough care must be taken throughout the collection, processing, transporting, and disposal of hazardous materials in order to reduce environmental dangers, as it cannot be disposed of in the environment since it is. That study looks at hazardous wastes, their many types, and how they are managed. Improved strategies for identifying the most convenient and ecologically friendly hazardous waste medication and disposal techniques are required. This document discusses the numerous hazardous wastes created by industry, as well as the nature of those wastes and several methods that can be used for managing the hazardous waste.

Aim: This study aims to observe the potential implementation of analytical methods based on digital image processing as an alternative method of colorimetric analysis that can be implemented in site. Methodology and Results: Pt-Co standard series solutions at concentrations of 5, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 concentration units (CU) were measured by spectrophotometric method and digitally enhanced colorimetric (DEC) method to obtain a response in the form of absorbance (Abs) and area under curve (AUC) value. Absorbance measurement was carried out at 317.5 nm (λ max). The AUC value was obtained from the 3-point RGB value measurements, made average so that a color band is produced, then quantified by translating the color band intensity into the response curve in ImageJ software. The Abs and AUC values of artificial samples are processed into CU values with linear equations resulting from linear regression test. The results of the calculation of CU values from the two measurement methods were tested using independent t test method to examine significant differences between the two measurement methods. Conclusion, significance and impact study: Coefficient of determination (R2) plot CU VS AUC = 0.8638, in independent t test was obtained p-value = 0.4246 at the 95% confidence level. Therefore, it can be concluded that digitally enhanced colorimetric could be used to determine water quality, especially color parameter in site measurement.

Aim: This study aimed to compare the secured landfill method and thermally sludge treatment through gasification, in order to determine their environmental impacts. Methodology and Results: The gate-to-gate LCA method was the implementation approach used to determine the, limits and assumptions to the actual condition. The experimental, theoretical mass balance calculation and secondary data of previous researches were used to carry out this study, with open-source openLCA software. In addition, the LCA was made up of four phases which include goal and scope definition, inventory analysis, impact assessment, and data interpretation. The simulation showed that the implementation of the thermal gasification process reduced the emission released to the atmosphere by lowering the hazardous sludge volume which is directly transported to the secured landfill. Conclusion, significance and impact study: Several assumptions and adjustments were made to the simulation results using the openLCA software, in the determined scope of study. Therefore, in conclusion, the thermal (gasification) treatment of hazardous sludge is further studied in connection with its implementation at the treatment plant. This was indicated by the acquisition of global warming potential impact category of 673 kg CO2 eq for direct disposal to secured landfill, which reduced to 424 kg CO2 eq during the implementation of thermal treatment. Conversely, there is a reduction in magnitude of impact by 37%.

Aim: This study aims to determine whether the application of eco enzyme affects the industrial waste activated sludge degradation and to compare the effects of eco enzyme made from oranges and tomatoes. Methodology and results: The experiments were done on the laboratory scale for 12 days by applying 10% of eco enzyme in the sludge samples. It showed both tomatoes and oranges eco enzymes can decrease the pH from 6.9 to 4.7 compared to control which was stable at 6.9. The reduction of COD, TSS, and VSS by tomato eco enzyme applications were 61%, 39% 41% respectively compared to by orange eco enzyme application that showed a higher reduction of 78%, 45%, 46% respectively. The control samples also show the reduction of COD, TSS, and VSS by 21%, 23%, 30% respectively. The reduction of organic content in the control samples of sludge (8.9%) was higher than the samples with eco enzyme (3.5%). Conclusion, significance, and impact study: The results showed that eco enzyme application significant statistically affected reduction of pH, COD, organic content, but not significant statistically on TSS and VSS reductions. Comparing the application of orange and tomatoes eco enzyme did not show the significant different treatment.

Monitoring of pollutant concentrations in surface water becomes a concern, considering the utilization of surface water as the raw water for drinking water treatment plants (WTP). The fluctuation of pollutant concentrations in surface water can affect the performance of WTP. This research was conducted to assess the potential for turbidity level prediction based on the calculation of the number and surface area of suspended particles through a digital image processing approach. Measurements of the amount and surface area were carried out in the form of laboratory-scale experiments using the open source software ImageJ 1.46r. The algorithm in ImageJ can convert pixels into a number “value” and surface area through a series of digital image processing steps, henceforth compared with the existing measurement method. The results showed that there was a strong correlation between the number of particles and the concentration of formazine suspension (r = 0.9821), but does not apply to the surface area. Referring to the results of laboratory experiments, it can be concluded that the approach to measure the number of suspended particles can be the basis for predicting the turbidity level in the turbidity range 100-800 NTU, but does not apply to the turbidity range 0.02-20 NTU.

PT ABC is an industry that produces hazardous and toxic waste. All waste generated is stored in temporary storage, but based on observations made, the existing temporary storage does not meet the standards set by the government. Therefore, a temporary storage area was redesigned at PT ABC in accordance with the standards set by the government. The objective of this study is to find a temporary storage place that complies with government regulations for PT ABC. The method used is to record the types, characteristics, and quantities produced by PT ABC, followed by existing observation, then proceed with the calculation of facility requirements according to SNI and individual calculations. A redesign is carried out by adjusting the calculation results, determining the required facilities, and making a design proposal. The results showed that PT ABC requires temporary storage of 6,1 m x 2,6 m x 4,4 m to accommodate all the waste generated for 3 months with the number of drums needed, namely 5 drums. The total ventilation needed is 6 pieces with a size of 0.5 m x 0.5 m. The required size of the spill container is 2.2 m x 1.2 m x 0.6 m, and it takes 3 lamps to illuminate the temporary storage.
