Abstract

Microalgae can be an ecological remediation agent known as phycoremediation. Understanding these factors is critical in producing the expected products efficiently. Several factors affect microalgae growth, including nutrients, temperature, pH, CO2 concentration, lighting, microalgae photosynthesis processes, and hydrodynamic factors. Microalgae Chlorella vulgaris has the potential to survive in media contaminated with heavy metal and high salinity levels. It can reduce the concentration of heavy metals in water through several mechanisms. Further research must be conducted to determine the factors influencing microalgae growth. The research was conducted to observe the growth rate of microalgae in a controlled photobioreactor. The cultivation was carried out in a plastic photobioreactor equipped with aeration, lighting, and the addition of nutrients. The first stage of the research was observations on C. vulgaris growth with 30% inoculum and 20% inoculum. The C. vulgaris growth rate is 0.133 cells/mL/day and 0.927 cells/mL/day, respectively. The second stage of the research was observations on C. vulgaris growth with 20‰ salinity, and the variation used is the aeration, 3 L/min, and 4 L/min. The C. vulgaris growth rate is 0.263 cells/mL/day and 0.236 cells/mL/day, respectively.

Abstract

The principle of reduce, reuse, recycle (3R) serves as the main reference in waste management, but further efforts are needed to handle non-recyclable materials. Based on the waste management hierarchy, the next step is energy recovery through waste-to-energy (WtE). WtE technology can generate renewable energy as a substitute for fossil fuels while reducing waste disposal in landfills. Various WtE technology options are available, depending on the heterogeneous characteristics of waste. According to the Ministry of Public Works and Housing, waste treatment technologies in Indonesia include physical, biological-chemical, and thermal processes. Although WtE offers benefits, its potential impacts must also be considered. This study reviews trends in Indonesia regarding the use of the life cycle assessment (LCA) method as a tool for evaluating different WtE technologies from an environmental perspective. The review covers the analyzed functional units, selection of impact categories, supporting software, and the application of sensitivity analysis and data uncertainty. The findings from LCA applications can assist policymakers in designing sustainable WtE management strategies.

Abstract

PT. XYZ is a manufacturing company that assembles bicycles. The company's problem is that there is excess capacity in the warehouse owned by PT. XYZ. Overcapacity occurs when the number of incoming goods exceeds the optimal capacity of the warehouse. The purpose of this study is to identify the cause of overcapacity in the warehouse of PT. XYZ's warehouse and to find a solution to the problem in order to prevent similar incidents in the future. The method used is root cause analysis and the tools used are fishbone diagram and 5-why analysis. The results of the study using the fishbone diagram show that there are four aspects that are the root causes, namely errors in purchasing planning (man), excessive use of pallets (method), accumulation of bicycle spare parts (material), use of warehouse capacity that is not optimal (environment). Each of these aspects has a known trigger root after applying the 5-why analysis. Once the triggers of each problem are known, the preparation of corrective actions, which are solutions, is accompanied by the company's commitment to implement the solution in order to prevent problems that have the potential to recur.

Abstract

With the rapid development of technology, this will affect the increasing demand for electrical energy, where the use of electrical energy generally uses fossil-based electrical energy. Therefore, with the presence of aluminum-air batteries with its existing advantages including high energy density, abundant raw materials and environmentally friendly properties as an alternative source solution, if built on a large scale it could be used for remote areas. In this research, the first experiment is conducted without using solar panels and the second experiment is conducted with solar panels. The test results show that aluminum air batteries connected to solar panels are more effective in producing a large enough voltage and current with a mixture of a small NaCl electrolyte solution, namely with a composition of 24 grams of salt mixed with 1 liter of water, which can produce a battery output of 14.1 volts and a current of 19.1 mA for direct current. One factor that determines the effectiveness of the performance of aluminum-air batteries is the concentration of the electrolyte solution used.

Abstract

Slaughterhouse waste is one of the sources of water pollution. If not properly managed, the slaughterhouse industry can have a significant negative impact on the environment and humans. The purpose of this study was to analyze the effectiveness of the combination of coconut shell charcoal filter-adsorption on the reduction of COD and TSS of slaughterhouse liquid waste. Slaughterhouse liquid waste is flowed into a filtration-adsorption reactor with a flow rate of 54 ml/minute and using the Slow Sand Filter (SSF) method, downflow flow with a continuous system. There are five reactors namely filtration-adsorption reactors A, B, C, D and E with different filter media in each reactor with sampling times of 0, 30, 60, 90 and 120 minutes. The variables measured were the effectiveness of the filter media reactor in reducing COD and TSS parameters, the adsorption capacity of reactors B and C, and the breakthrough time on the filter media of reactors B and C. The results showed that the best reactor effectiveness was in reactor E, which was able to remove 75% COD and 70.8% TSS parameters with a mesh size of 100 and a sampling time of 120 minutes. The highest adsorption capacity on 10 mesh and 100 mesh coconut shell activated carbon media was 0.0222 mg/mg adsorbent and 0.0233 mg/mg adsorbent, respectively. The breakthrough time obtained varied from 0.78 days to 1.60 days in each reactor.

Abstract

Concrete is the main material used in construction and is a mixture of sand, gravel, cement and air. The addition of materials such as coffee grounds can be an environmentally friendly alternative to partially replace cement in concrete mixes. This study examines the effect of variations in the addition of coffee grounds on the compressive strength of concrete, with the proportions of coffee grounds tested being 0%, 2.5%, 5%, and 7.5%. Tests were conducted on concrete cylinders of 150 mm diameter and 300 mm height, and the compressive strength was measured after 28 days of treatment. The test results showed that the addition of coffee grounds caused a decrease in the compressive strength of the concrete, with the average compressive strength values at 0%, 2.5%, 5%, and 7.5% variations being 36.78 MPa, 20.94 MPa, 16.98 MPa, and 11.04 MPa, respectively. Although coffee grounds cannot completely replace cement, this material can potentially be used as an environmentally friendly alternative for non-structural concrete applications. It can reduce the waste of coffee grounds while reducing the use of cement in construction, albeit with an impact on concrete strength.

Abstract

The cooling tower circulating pump circulates cooling water throughout the cooling system by controlling the rotation of the circulating pump using an inverter. The method in this research uses quantitative methods. The research aims to analyze two circulating pump units with and without inverter. The results of one year of research on circulation pumps without inverter consumed 48,180 kWh of electrical energy and circulation pumps with inverter consumed 31,083.4 kWh of electrical energy, the resulting electrical energy savings was 17,096.6 kWh at a cost of IDR 19,058,263.9. Using an inverter can save electric energy consumption because the speed of the circulation pump can be adjusted, which causes the output voltage to vary and not always remain constant at the maximum value, so the electric energy consumption is lower.

Abstract

Landfills generate methane gas (CH₄) as a result of the anaerobic decomposition of organic waste. This gas has the potential to serve as a renewable energy source if managed properly. This study aims to analyze the methane gas emission potential from the Sekoto landfill using the Landfill Gas Emission Model (LandGEM) and convert it into electricity and LPG. Annual waste generation data from 2021 to 2026 was used as input for the LandGEM model to estimate methane gas emissions. The modeling results indicate that peak methane production will occur in 2027, with a total of 4,247,951 m³/year. The potential electrical energy generated from this methane gas reaches 349,421,156.64 kWh per year, equivalent to 39,888.26 MWh. Additionally, the potential conversion of methane gas to LPG is estimated at 1,954,057.46 kg of LPG per year or approximately 5,353 kg per day. Utilizing methane from the Sekoto landfill as an alternative energy source not only contributes to renewable energy supply but also reduces greenhouse gas emissions that impact global warming. With a more efficient gas harvesting system and adequate processing infrastructure, methane gas can be converted into a more beneficial energy source for the community. This study confirms that optimizing landfill gas management can enhance energy sustainability while mitigating the environmental impact caused by methane emissions.
