Abstract

Aktivitas masyarakat disekitar Sungai Musi menjadikannya rentan akan kontaminasi libah termasuk plastik dan mikroplastik. Mikroplastik memiliki dampak akumulasi yang buruk terhadap kesehatan terutama apabila terkonsumsi oleh biota perairan seperti ikan. Salah satu ikan konsumsi yang biasa ditangkap di Sungai Musi adalah ikan baung (Hemibagrus nemurus). Penelitian ini mencoba memberikan gambaran seberapa jauh kontaminasi mikroplastik terhadap keberadaan ikan baung di Sungai Musi. Pengambilan sampel dilakukan pada dua titik lokasi pada sungai Musi yaitu Meriak, dan Mariana. Analisa dilakukan terhadap isi usus ikan baung dengan menghitung jumlah mikroplastik didalamnya, mengamati bentuk dan warnanya, serta menganalisis polimernya menggunakan FT-IR. Diperoleh hasil jumlah mikroplastik pada ikan baung di wilayah Meriak sekitar 14±18,7 partikel, sedangkan pada wilayah Mariana berkisar 28±18,5 partikel. Keberadaan mikroplastik dalam usus ikan memiliki keterkaitan dengan aktivitas makan dari ikan baung. Ikan baung dari Meriak cenderung menelan partikel mikroplastik berbentuk fragmen, sedangkan sampel dari Mariana banyak menelan mikroplastik berbentuk fiber. Analisis FT-IR memeberikan informasi bahwa jenis polimer mikroplastik dalam usus ikan baung adalah berupa polystyrene (PS), polypropylene (PP), high-density polyethylene (HDPE), low-density polyethylene (LDPE) dan nylon atau polyamida.

Abstract

PT Bukit Asam Tbk has adopted the use of plant-based diesel oil in compliance with the rules established by the Minister of Energy and Mineral Resources No. 12 of 2015 from previously using fossil diesel. One of the decarbonization program's initiatives to reduce emissions is to replace the use of fossil fuels with biodiesel for all production equipment. To obtain results on the decrease or increase in the environmental quality of the use of fossil fuels and biodiesel, this research requires comparative data obtained from the results of ambient air quality, emissions, and opacity test. Based on research data in the years 2018 – 2022, the emission quality test was obtained with an average CO parameter of 550.83 mg/nm3, which exceeded the quality standard of 540 mg/nm3, SO2 parameter of 79.03 mg/nm3 from the quality standard of 900 mg/nm3. The NO2 parameter is 161.29b mg/nm3 from the quality standard of 1200 mg/nm3, with the quality standard parameters referring to thw Minister of Environment and Forestry Regulation No. 15 of 2019. Based on quantitative analysis approaches method and trend analysis obtained the emission results experienced an increase with trend line analysis but were still below the quality standards. The results at IUP Banko Barat for mobile equipment sources were obtained at 5.23% HSU, while for static equipment sources, they were obtained at 9.88% HSU from the quality standard of 40% based on South Sumatera Governor Regulation No. 06 of 2016. It can be concluded that the variance of fuel use for the 2018-2022 period has no significant effect on the air quality test emissions and opacity results because it is still below the quality standard.

Abstract

The limitations of CuO photocatalyst include high electron–hole recombination and low charge-transfer efficiency. In this context, doping with Fe3O4 is used to form a heterojunction, which enhances charge separation, increases electron transfer, and imparts magnetic properties for easy separation and reuse of the catalyst. Therefore, this study aimed to synthesize a biphasic CuO/Fe₃O₄ composite using Rhodomyrtus tomentosa leaf extract as a green reducing agent, and evaluate the performance as a photocatalyst for the degradation of Crystal Violet Dye (CVD). Structural, morphological, optical, and magnetic properties were characterized using X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM–EDX), UV–Vis diffuse reflectance spectroscopy (DRS), and vibrating sample magnetometer (VSM). XRD patterns confirmed the coexistence of CuO and Fe₃O₄ phases, indicating successful composite formation. VSM analysis reported that the composite had magnetic properties with a saturation magnetization and band gap values of 46.92 emu/g and 1.63 eV, respectively. Process optimization was conducted using Response Surface Methodology (RSM) based on Central Composite Design (CCD). The results showed that the quadratic model was the most appropriate and statistically significant model, indicated by a p-value < 0.05 with a coefficient of determination (R2) of 0.9953. In addition, optimization of the degradation process led to CVD degradation efficiency of 98.73% under optimal conditions of initial concentration of 25.4 mg/L, pH 9.5, and irradiation time of 39.4 min with a visible-light radiation source. The composite also reported good reusability, retaining 92.11% of degradation efficiency after five cycles, confirming the potential as a magnetically recoverable, environmentally sustainable photocatalyst for wastewater treatment applications.

Abstract

The availability of clean water is an essential element for supporting the life cycle and sustainable development. The efficiency of providing raw water sources is an important factor for adequate water quantity and quality. This study examines the effectiveness of alum compared with coal-based activated carbon in the removal of Fe, Mn, and turbidity in raw water from the Lematang River, Muara Enim Regency. Activated carbon in this study was produced using a KOH activator with varying activation temperatures (700 °C, 800 °C, and 900 °C). The research results showed that the quality of the third activated carbon met the active carbon quality standards (moisture, ash content, Methylene blue dye and iodine adsorption capacity), but the activated carbon with activation at a temperature of 800 °C had the largest surface area. Activated carbon was proven more effective in reducing Fe and Mn concentrations than alum, while alum was superior in reducing turbidity. After three cycles of activated carbon regeneration, the reduction in Fe and Mn remained below 5%. These results show that activated carbon is a cost-effective and eco-friendly option for raw water treatment.Keywords: Coal, activated carbon, alum, raw water, regeneration

Abstract

This study aimed to optimize the production of Manganese Peroxidase (MnP) enzyme from Pleurotus ostreatus using agricultural waste substrates such as coffee grounds (CG) and rice bran (RB) through Response Surface Methodology (RSM) approach. Optimization was conducted using a Central Composite Design (CCD) with three main variables, namely MnSO₄ concentration (0.5-1.5) mM, incubation temperature (25-35) °C, and reaction time (20-30) min. The enzyme fractionation process was carried out by ammonium sulfate saturation (0-20%), (20-40%), (40-60%), followed by dialysis, and SDS-PAGE analysis. The results showed that the 0-20% fraction of CG:RB (50:50) substrate had the highest enzyme activity, which was 20.588 ± 0.141 U/mL, with the highest specific activity of 76.967 ± 0.325 U/mg. The highest protein content was found in CG:RB (0:100) substrate at 0.825 ± 0.016 mg/mL. However, the enzyme activity was lower due to the presence of non-enzymatic proteins and natural inhibitors. This study successfully demonstrated that the substrate combination of CG:RB (50:50) provided optimal results for MnP production. The Response Surface Methodology proved effective in optimizing process variables, providing great potential for biotechnology applications using agricultural waste as an environmentally friendly raw material.Keywords: Pleurotus ostreatus, Manganese Peroxidase, Coffee Dregs, Rice Bran, RSM, SDS-PAGE
