Abstract

The increase in the electroplating industry resulted in a large number of heavy metal wastes that are harmful to the environment, for example, hexavalent chromium waste. The Bintaro which contains cellulose is considered as a potential adsorbent to remove heavy metals. Therefore, a comparative study on the adsorption capacity of continuous adsorption was carried out in reducing the concentration of heavy metal Cr6+ in electroplating wastewater. The characterization itself can be done by testing the moisture content and ash content and SEM testing. The study of the adsorption capacity in a continuous process is generally carried out with Thomas modeling, where this research is carried out by a continuous adsorption process with variations in the adsorbent mass of 50 grams, 100 grams, 150 grams, 200 grams, and 250 grams. The best results were obtained to remove Cr6+ metal which was 94.4% in the Bintaro shell adsorbent type with a mass of 250 grams. The continuous adsorption process obtained the highest Thomas constant (Kth) value and the highest adsorption capacity (qo), namely using Bintaro shell activated carbon with a mass of 250 grams with an absorbance capacity value of 0.443mg / g. The results showed that the activated carbon of Bintaro shell showed that they were quite effective as adsorbents in the adsorption process to remove heavy metal Cr6+

Abstract

Wastewater has been giving a high contribution to the quality of water bodies. Tofu wastewater is one of the contributors since it might contain high organic loading. Microalgae is one of the promising solutions to improve wastewater treatment, especially organic wastewater. However, every microalga has its specific properties and it will affect the quality of treated wastewater. This study aims to compare Chlorella vulgaris and Spirulina platensis in an oxidation ditch algae reactor (ODAR) for treating tofu wastewater. The ODAR system was set up under ratio wastewater and microalgae 1:1, the sample was taken every day for 7 days of observation. The sample was analyzed for BOD, DO, and Chlorophyll-a. The results showed that Spirulina platensis has a higher performance in removing organic pollutants than Chlorella vulgaris, which is shown 60% BOD removal, higher DO concentration (5-8 mg/L), and 2,67 mg/L of Chlorophyll-a. Performance of Spirulina plantesis in treating organic wastewater was indicated as a fast-growing microalga than Chlorella vulgaris.

Abstract

The high nitrate content in domestic wastewater can cause problems for the environment. Improved quality of processed wastewater can use biological treatment with oxidation ditch combined with microalgae Spirulina platensis. The growth process of Spirulina platensis requires nutrients such as nitrates. In the study, variations in aeration conditions (continuous aeration and intermittent aeration) were conducted to create anoxic conditions in oxidation ditch algae reactors. Observations were made for 5 days with the aeration process using a brush aerator rotation speed of 60 rpm. The results showed that the microalgae Spirulina platensis has the potential to be effective in degrading nitrate concentrations in domestic wastewater. In addition, intermittent aeration has a significant effect on nitrate degradation in domestic wastewater. This is indicated by a decrease in nitrate with a percentage removal of 73.71% from the initial nitrate concentration of 5.82 mg/l to 1.53 mg/l during intermittent aeration.

Abstract

Oxidation ditch (OD) is a tub used to treat wastewater by utilizing oxygen and microorganisms contained in it to determine its ability to reduce the release of organic substances. Oxidation Ditch Algae Reactor (ODAR) is a biological wastewater treatment that utilizes the symbiosis between algae and bacteria in water. The results of biological processes contain organic material called effluent organic matter (EfOM). This research aims to investigate the characterization of effluent organic matter (EfOM) produced from the Oxidation ditch (OD) process with and without algae both in continuous aeration (oxic) and intermittent aeration (oxic-anoxic) conditions in domestic household wastewater and microalgae Spirulina platensis. Characterizing effluent organic matter (EfOM) is a crucial thing to understand its ability to treat wastewater. Based on the analysis results, the characterization of effluent organic matter (EfOM) in the oxidation ditch process using an algae ratio of 1:1 in continuous aeration (oxic) conditions through the UV254 test was identified as containing the highest aromatic organic matter up to 59.68%. Meanwhile, without using algae with a 1:0 ratio of intermittent aeration (oxic-anoxic) conditions, the lowest decrease in aromatic organic matter content reached 34.79%.

Abstract

Many advantages are obtained in treatment using microalgae. Microalgae treatment using an oxidation ditch can remove organic matter in wastewater. On the other side, the wastewater treatment using microalgae with oxidation ditch algae reactor (ODAR) to reduce organic matter also produces by-products that are harmful if dissolved in water. Processing in ODAR has Effluent Organic Matter (EfOM) and Algae Organic Matter (AOM) which are by-products of the microalgae process. The content of these compounds can lead to the formation of DBPs in water. This research was conducted on control variation (without microalgae) and variation of the volume of waste and microalgae 1:3, with oxic and oxic-anoxic conditions. Spectroscopy FTIR test is used to determine the organic matter contained through its functional groups. In the oxic-anoxic control variation, the FTIR percentage increased to 46.63% on the fifth day. In control oxic variation, it decreased to 46.12%. Meanwhile, in the oxic-anoxic 1:3 variation, the percentage decreased on the fifth day to 46.39%, and in oxic conditions, the rate was 46.8%. From the results obtained, the addition of microalgae can increase the content of organic matter in processing due to the by-products produced by microalgae and bacteria in processing.

Abstract

Chlorella sp is a species of green algae that can’t have the ability to move. Chlorella sp is a biofilter that removes nutrients and pollutants in wastewater. Chlorella sp also functions as a catalyst in the photosynthesis process, because there is a lot of chlorophyll. In this research, domestic waste was used as an experimental medium. Before running the oxidation ditch reactor, microalgae cultivation was carried out to increase the number of microalgae needed for research. Then the microalgae acclimatization was carried out to determine the maximum acceptable limit for the microalgae Chlorella sp. The oxidation ditch reactor has a capacity of 250 liters and is used in conditions of 60 rpm oxic and 60 rpm oxic-anoxic, and sampling is carried out every day for 5 days. This research was conducted to determine the role and effectiveness of Chlorella Sp. in degrading NO3- and PO43- content in domestic wastewater treatment. From the research results, it can be seen that the microalgae Chlorella Sp. was able to remove the maximum nitrate of 81,96% with an initial nitrate 5,82 mg/L to 1,05 mg/L. In addition, the microalgae Chlorella Sp. was also able to remove maximum phosphate of 82,09% with an initial phosphate value of 2,72 mg/L to 0,6 mg/L.

Abstract

Adsorption is an accumulation of contact between gas or liquid molecules with a solid surface and some molecules attached to the surface. This study uses adsorption as a pretreatment of membrane processing. The adsorption process is affected by several factors, including the flow rate used in the adsorption process. This study aimed to determine the effect of water flow rate on the adsorption process in removing Total organic Carbon (TOC) using Calgon and Haycarb Adsorbent. The characteristics of the wastewater used are effluent of wastewater treatment from alcohol production that remains contains Total Organic Carbon (TOC). Variation of the flow rate used is 39 mL/minute, 29 mL/minute, and 23 mL/minute. The effect of flow rate on adsorption pretreatment in removing Total Organic Carbon (TOC) on Calgon adsorbent showed that 23 mL/minute was the most effective in reducing TOC values. On the other hand, using Haycarb absorbent on 23 mL/min flow rates was less effective in removing TOC values. The Haycarb adsorbent effectiveness is shown by the morphology of the initial and final results of EDX, where the adsorbent pore of Haycarb is not filled with absorbate.

Abstract

The biggest source of river water pollution is domestic wastewater, about 60-70% with 6.1% treatment and 40% of the pollution comes from industry or others and is exacerbated by the uncontrolled algae growth. The diversity of algal organic matter (AOM) in domestic wastewater causes several problems in water treatment. Fluorescence Excitation Emission Matrix (FEEM) has been widely used to determine the structural and compositional characteristics of molecules. The purpose of this study was to determine the characteristics of the AOM fraction produced by the microalgae Spirulina platensis using FEEM. The peak percentage of EEM and the Fluorescence Regional Index (FRI) was used to represent the substance contained in the sample. The results showed the microalgae Spirulina platensis identified as containing fraction aromatic protein-like, fulvic acid-like, soluble microbial product-like, and humic acid-like where the percentage of FRI of each fraction fluctuates due to internal factors such as microbial carbon sources and external factors such as temperature and oxygen supply.

Abstract

Islamic Boarding School throughout the history of the development of Indonesian society has played an important role, especially in the development of religious education. Currently, there is a phenomenon of the transformation of the role of Islamic Boarding School which focuses on the balance between religious knowledge and science. However, so far, capacity-building activities during the Covid-19 pandemic are considered ineffective. The batik design training program using CorelDraw software is implemented as a form of the OPOP program for the development of an Islamic Boarding School-based economy. The method of implementing this activity is by conducting training, implementation, mentoring, and networking. From the results of the field evaluation, the economic activities of the pesantren have received a very positive response from the students.
