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

Compensation is an effort to reduce the pollution load from other sectors to replace the wastewater load that will be discharged by businesses and/or activities due to river water quality being exceeded. Currently, most large rivers in Indonesia have exceeded the water quality standards set by the government. The one of the hospitals in Jember plans to discharge wastewater into the Bedadung River. However, the Biochemical Oxygen Demand (BOD) quality standard for the Bedadung River has been exceeded. Therefore, alternative compensation activities are needed to reduce the BOD levels of the Bedadung River. Bathing, Washing, and Toilet (MCK) facilities with biofilter septic tanks were chosen. This technology is considered to be able to effectively reduce the BOD concentration of domestic waste before being discharged into the environment. This study aims to calculate the potential for reducing the BOD pollutant load in Bedadung River water if compensation is carried out through the construction of MCK with a biofilter septic tank system, so that it is expected to provide a significant contribution to improving river water quality while supporting the sustainability of hospital activities.

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

Increased production in the lubricant industry has become a significant issue because it generates production waste in the form of packaging, plastic, and paper waste as a direct consequence of manufacturing activities. Proper and systematic waste management is essential to reduce environmental impacts, comply with regulations, and support responsible and sustainable business practices. Lubricant production waste can damage the ecosystem and surrounding environment if not managed properly, so continuous innovation is needed to minimize environmental risks and reduce potential economic losses for the company. This study aims to analyze and implement effective waste management strategies using a combination of qualitative and quantitative approaches, including in-depth interviews with relevant stakeholders and analysis of secondary data obtained from company records. The waste management process begins with several waste reduction programs applied during the production stage to limit waste generation. Furthermore, the waste storage facility (TPS) available on the company’s premises, covering an area of 59 m², is capable of accommodating approximately 60% of the total waste that must be processed internally before further treatment or disposal.

Abstract

This study analyzes the conditions of extreme overcapacity in an installed exhaust ventilation system (Qinstalled = 18.00 /minute) that serves four acid cabinet units, specifically for the storage of volatile Hazardous and Toxic Materials (B3) such as toluene and methanol in tightly sealed containers. Although high capacity ensures safety, this practice causes significant energy inefficiency and unnecessary negative pressure problems in the room. Based on engineering analysis using a conservative Air Change Rate (ACR) standard of for liquid storage of 1.38 /minute. By applying the industry standard safety factor (FoS) of 1.5, the ideal flow rate (Qideal) that must be allocated is 2.07 . The optimization analysis concludes that the currently installed system is theoretically capable of safely and efficiently serving 8 units of volatile storage acid cabinets, with the addition of 4 new cabinets to maximize efficiency and reduce energy waste. This utilizes 92% of the total capacity while maintaining a safety factor above 1.5.

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.

Abstract

Waste is the remaining material from human activities that is no longer needed. Waste must go through a good handling process so that it does not cause problems for the environment. Organic waste can provide benefits if managed properly. Organic waste processing requires appropriate technology so that no new waste is generated from the processed results. One of these technologies uses the maggot cultivation method carried out at the Selopuro TPA (Final Processing Place). After the maggots grow large due to the process of decomposing organic waste, maggots can be used as the main feed in catfish cultivation which is also found at the Selopuro TPA. The purpose of this activity is to analyze the effectiveness of the maggot cultivation method in reducing organic waste at the Selopuro TPA. The implementation method is by direct observation. The data used in this study is primary data. The results of the study show that managing organic waste using maggots is an environmentally friendly and inexpensive processing alternative, and is able to decompose organic waste faster.
