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.

Abstract

Universitas Pembangunan Nasional “Veteran” Jawa Timur is one of the public facilities that produces solid waste, including organic waste, inorganic, and hazardous waste. Waste that can be immediately utilized is organic waste consisting of food waste and leaves and twigs. Therefore, appropriate technology is needed to process organic waste into more useful goods and as a better management alternative through community service. One of the alternatives for processing waste is recycling it into compost using Simultaneous Composting Technology with EM4 and MOL. The main target of this community service is to reduce waste and utilize university waste with appropriate technology for regional coverage and national coverage in the future. The method of this community service is to separate waste between organic and non-organic, selected organic waste is cut by a hammer mill, and then other waste from the canteen activity is made Local Microorganisms (MOLs) as the decaying medium in the composite production of the organic garbage processing device reactor. As a result, this community service has been running smoothly and well. The results of this community service have a positive impact through the use of organic waste into compost which can be utilized by the internal campus and generate economic value.

Abstract

Aluminum is an inorganic material that cannot be decomposed naturally in nature, while its presence in our lives is very abundant and quite crucial. One of its uses is as a raw material for food or drink cans. In the United States alone in 2012 around 38.2 billion cans of food or drink were produced. Therefore, efforts are needed to reduce aluminum waste. One use that can be made is by extracting the aluminum content in it to be used as raw material for alum coagulants and PAC. The aluminum that has been successfully extracted is then added with solutions that can cause polymerization and form alum and PAC coagulants. Next, the resulting synthetic coagulant was tested for its ability to reduce turbidity in laundry waste. Laundry waste itself was chosen because the waste processing is still simple, and generally, this type of waste contains suspended solids which can come from dirt attached to clothes or chemicals used in detergents. In this study, coagulation and flocculation were carried out with 500 mL of laundry waste sample taken and a synthetic coagulant dose of 100 PPM. After the coagulation-flocculation process was carried out, the sample was deposited with varying settling times of 30 minutes, 60 minutes, and 90 minutes. From the results of this research, it was found that synthetic PAC coagulant was more effective than alum in reducing turbidity in laundry waste. At the most effective deposition time, namely a deposition time variation of 30 minutes, the removal percentage was 57%.
