Abstract

In this research, the concentration of carbon monoxide (CO) on Jalan Raya Darmo, Surabaya City, which is one of the main highways with heavy traffic, was measured and analyzed. The main aim of this research is to measure CO concentrations and create practical plans to reduce pollution levels. The process consists of collecting information about CO concentration, wind speed, temperature, and air humidity using instruments including hygrometers, anemometers, and CO analyzers. The CO distribution was modeled using the AERMOD dispersion model according to the collected data and the associated meteorological conditions. The research findings revealed that CO concentrations varied significantly depending on traffic volume and weather, with the highest figure being 13,704 μg/m3 on Friday afternoon and the lowest figure being 5,224 μg/m3 on Monday morning. A strong CO distribution pattern was found towards the North, Northeast, West and Southwest using AERMOD for distribution analysis. The research conclusion proves that the amount of CO on Jalan Raya Darmo is significantly influenced by weather and traffic density. It is recommended that risk management techniques be used, such as routine motor vehicle maintenance, implementation of odd-even programs, and regular air quality audits to manage and reduce air pollution.

Abstract

This study examines the comparative performance of recycled glass and silica sand as filter media in the slow sand filtration process to treat laundry wastewater. The main objective of this study was to evaluate the efficiency of recycled glass and silica sand in reducing Total Suspended Solids (TSS), turbidity, and phosphate content in laundry wastewater effluent. The selection of recycled glass as a filtration medium is due to its characteristic of having a small sphericity value so that its porosity value is large which results in a small headloss value. The use of recycled glass as an alternative media is an effort to reduce the exploitation of the use of sand media in filtration. The results of the study showed that the use of recycled glass was quite efficient than silica sand in reducing TSS and turbidity with a percentage of TSS removal (94%% vs 90%) and turbidity (90,57% vs 86,04%). While in phosphate removal, silica sand was more efficient than recycled glass with a percentage of removal (46,74% vs 83,48%). Before the research was conducted, a maturation phase was carried out for 2 weeks to form the schmutzdecke layer. The addition of Effective Microorganism 4 (EM4) was carried out to help the growth of the schmutzdecke layer in this study.

Abstract

The rapid growth of the laundry industry in Indonesia, recorded in 2021 there were more than 30,000 laundries spread throughout Indonesia with a business growth of 15-20% per year (Bisnis et al, 2021) the increased laundry industry means more wastewater will be produced. If it is not treated properly before being discharged into water bodies, it can pollute water bodies and the ecosystems inside. One of the processing methods is the Moving Bed Biofilm Reactor (MBBR) which is a biological method by utilizing microorganisms to form a biofilms and stick to carrier media and then move dynamically so that contact occurs between waste and microorganisms effectively which can degrade pollutants in laundry waste, the more bacteria added and the longer the contact time, the more pollutants will be degraded. In this study, variations in the addition of Pseudomonas aeruginosa bacteria were carried out by 0%, 3%, 5%, 7% and 10% with contact times of 7 hours, 14 hours, 21 hours and 28 hours to degrade COD, phosphate and detergent parameters in laundry wastewater. The greatest removal efficiency was obtained at the addition of 10% bacteria and a contact time of 28 hours, namely 84% COD, 96% detergent and 74% phosphate. The number of colonies in the biofilm with the addition of 0% was 101,000 CFU/mL, 3% was 110,000 CFU/mL, 5% was 184,000 CFU/mL, 7% was 234,000 CFU/mL and 10% was 338,000 CFU/mL.

Abstract

The electroplating industry produces liquid waste containing dissolved heavy metals, such as copper and nickel. If this waste is not managed properly, it has the potential to cause environmental pollution. One method that can be used to address this issue, particularly with regard to the heavy metal parameters Cu and Ni, is phytoremediation. Phytoremediation utilises plants to remove pollutants from the environment. Plants that can absorb heavy metals in this way include napier grass (Pennisetum purpureum) and speargrass (Imperata cylindrica). This study aims to determine the ability of these two plant species to absorb and remove heavy metals (Cu and Ni) from electroplating waste. The research was conducted using a batch system with variations in sampling time on days 7, 14, 21, 28 and 35. Napier grass produced the best results on day 21, with reduction efficiencies of 85.7% for Cu and 82.5% for Ni. Meanwhile, speargrass produced the most optimal results on day 35, reducing Cu by 89.2% and Ni by 87.3%. Based on these results, speargrass proved to be more effective than napier grass in reducing the levels of the heavy metals copper (Cu) and nickel (Ni) in electroplating waste.

Abstract

Biogas is a potential renewable energy source, but the content of impurity gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) reduces its quality and efficiency as a fuel. This study aims to analyze the effectiveness of the adsorption method using a combination of coconut shell activated carbon and natural zeolite in increasing methane (CH4) levels in biogas. The biogas used was produced from a cattle farm in Carangwulung Village. The variables tested included variations in the composition of activated carbon (C) and zeolite (Z) adsorbents with biogas flow rates (0.2; 0.4; and 0.6 L/min). The test was carried out with an adsorbent mass of 300 grams activated by KOH and the resulting pressure ranged from 9–13 mbar. The results showed that the adsorbent composition of 50C:50Z with a flow rate of 0.2 L/min gave the best performance. Under these conditions, CH4 levels could increase from 45% to 87%, where there was an increase in methane by 48%. The adsorption process at low flow rates provides optimal contact time between gas and adsorbent, thus increasing the efficiency of increasing CH4 levels. Thus, the combination of coconut shell activated carbon and natural zeolite at low flow rates is effective in improving biogas quality through the adsorption process.

Abstract

Groundwater treatment to reduce Coliform Bacteria levels generally still uses chlorine chemicals. Although effective, on the other hand, chlorine chemicals cause another problem, namely residual chlorine which is harmful to health if the treated water is used directly. Therefore, ceramic membranes can be used as an alternative to degrade Coliform Bacteria levels without causing side effects. The materials used as components of the ceramic membrane are clay, zeolite and coconut shell charcoal, with 3 groups of composition comparisons and 2 types of thickness. This research is experimental by carrying out a simple filtration process using a tube continuously, within an operating period of 8 hours. This study aims to analyze the effect of variations in the composition and thickness of the ceramic membrane on its performance used as filtration. The results of the filtration process show that the variation in the composition of the membrane 50%:25%:25% with a thickness of 2.5 cm has the highest reduction efficiency reaching 95.88%. This ceramic membrane variation has the least mixture of coconut charcoal. The study revealed that the mixture of additives in the form of coconut charcoal and membrane thickness play an important role in pore formation. The more clay and coconut shell charcoal are mixed and the thicker the membrane is made, the more the ceramic membrane's ability to reduce water pollutant levels will increase.
