Abstract

Fungal infections are known to be a common global health problem, especially as resistance to conventional antifungal drugs increases. Innovative solutions are needed to overcome this problem. This review aims to explore the potential application of nanotechnology to nickel oxide materials in inhibiting the growth of pathogenic fungi, as well as investigating the ability of nanosized nickel oxide as an innovative option in overcoming antifungal problems. The use of nickel oxide nanomaterial as an antifungal agent can produce efficient healing in treating fungal infections which are currently difficult to treat. Information explaining the potential side effects or long-term effects of this method is essential to ensure that the use of this agent does not harm the patient's health. Nano-sized nickel oxide has the ability to interact with other living things in an ecosystem. Therefore, to understand possible environmental risks, research is needed on the concept of ecological impacts on these materials. To increase awareness of the potential use of nano nickel oxide in the treatment of fungal infections, it is important to make this nickel oxide material available to the general public. Global consistency of patient treatment can be ensured through the establishment of well-defined and standardized protocols for the application of nickel oxide nanoparticles in the treatment of fungal infections.

Abstract

Mercury waste from unlicensed gold mining (PETI) is absorbed by the soil, so that the soil contains Mercury (Hg). This will cause environmental pollution. The Hg waste treatment method using the phytoremediation method has been able to bind Hg contained in the soil. However, phytoremediation of Hg waste from tailings soil using vetiver plants (Vetiveria zizanioides L.) has never been specifically studied. This study aims to determine the removal of Hg from soil contaminated with traditional gold mining tailings waste to determine the effect of Hg levels in the soil on the growth of Vetiveria zizanioides L. Vetiveria zizanioides L. plants in the soils that previously had heavy metal Hg as a pollutant with concentration variations of 1.8816 ppm and 1.9113 ppm and harvest variations of 7, 14, and 21 days. The results showed that Vetiveria zizanioides L. can accumulate Hg in the roots, soil, and leaves. The highest Hg accumulation in the roots of all types of concentration variations of 1.8816 ppm and 1.9113 ppm were 1.52 µg/g, 1.52 µg/g and 1.32 µg/g; 1.254 µg/g, 0.6813 µg/g and 0.59 µg/g on stems; while 1.02 µg/g, 0.49 µg/g and 0.04 µg/g on the soil. From the data that has been presented, it can be seen that the sample of Vetiveria zizanioides L. is able and effective in reducing the concentration levels of contaminants contained in tailings waste soil. The results of a simple linear regression test for Hg waste treatment showed that there was an effect of time/day on the decrease in the levels of the test parameters. The results indicate the use of Vetiveria zizanioides L has the potential to be used in the treatment of Hg-contaminated waste soil.

Abstract

The increasing demand for meat has increased the number of livestock slaughtered. An increase in cuts means an increase in the waste generated. One of the wastewater treatment techniques is the aluminium (Al) plate electrocoagulation method. Electrocoagulation is a coagulation process or coagulation and deposition of fine particles in wastewater by utilizing electrical energy through an electrolysis process so that it can degrade pollutants or contaminants in RPH liquid waste. This research was conducted to determine the effect of variations in current density and contact time and their effectiveness in reducing levels of COD and TSS, as well as increasing DO and optimum pH changes in abattoir waste. The current density variations used are 40, 45 and 50 A/m2 with 30, 60, 90, 120, 150 and 180 minutes of contact times. The effectiveness of electrocoagulation on the decrease in the highest TSS value was 96.04%, and COD was 76.81%, with a contact time of 180 minutes and a current density of 50 A/m2. The pH value increased at 50 A/m2 current density with a contact time of 180 minutes, an increase from 5.9 to 8.1, and the DO value increased at a current density of 50 A/m2 with a contact time of 180 minutes, an increase from 1.2 to 4,3 mg/L.

Abstract

Limbah laundry merupakan limbah yang berasal dari kegiatan pencucian pakaian yang menggunakan deterjen, sabun atau bahan pembersih lainnya. Salah satu metode untuk menurunkan kadar pencemar pada limbah laundry yaitu melalui proses koagulasi dan flokulasi. Tujuan penelitian ini untuk mengetahui efektivitas biokoagulan biji pepaya (Carica papaya L.) dalam menurunkan kadar pH, COD, TSS dan fosfat pada limbah laundry serta mengetahui pengaruh variasi massa biokoagulan biji pepaya (Carica papaya L.) terhadap penurunan kadar pH, COD,TSS dan fosfat pada limbah laundry. Variasi massa biokoagulan biji pepaya yaitu 2, 3, 4 dan 5 g. Hasil analisis perlakuan menggunakan biokoagulan biji papaya menurunkan nilai pH dari kadar pH awal 8,1 menjadi 6,5 pada massa biokoagulan biji pepaya 4 g dan masih memenuhi rentang pH 6−9 sesuai baku mutu. Penurunan kadar COD dan TSS yang terbaik dari penelitian ini pada massa biokoagulan biji pepaya 4 g dengan persentase penurunan COD sebesar 54% dan TSS sebesar 33%, namun tidak memenuhi baku mutu. Semakin besar massa biokoagulan biji pepaya maka semakin besar pula penurunan kadar pH, COD dan TSS. Berbeda dengan kadar fosfat yang semakin meningkat seiring dengan meningkatnya massa biokoagulan biji pepaya. Oleh karena itu, penggunaan biokoagulan biji pepaya masih belum efektif dalam menurunkan kadar pencemar pada limbah laundry.

Abstract

Restaurant liquid waste contains elevated pollutant levels and is commonly discharged directly into the environment, leading to adverse impacts on ecosystems and aquatic life. The traditional methods for processing such wastewater often involve extensive land usage and complicated operations, posing challenges for effective treatment. Therefore, there is a need for a more practical technology to manage restaurant liquid waste, and one promising approach is the utilization of membrane technology for wastewater treatment. In this study, the researchers employed a combination process of multilevel filters with downflow flow and PES membrane ultrafiltration to treat the restaurant liquid waste. The multilevel filter comprised several layers of filter media, including silica sand, activated carbon, zeolite, and gravel, with specific thicknesses on a PVC pipe. For the PES membrane, two different concentrations were tested: 15% and 20% PES. To evaluate the efficiency of the treatment process, pollutant parameters such as pH, TSS (Total Suspended Solids), COD (Chemical Oxygen Demand), and turbidity were measured. The results indicated significant pollutant reduction: pH levels could reach 6.9, TSS degradation achieved up to 98.37%, COD degradation up to 88.14%, and turbidity degradation up to 97.03%. Based on the outcomes, the most effective treatment for converting restaurant wastewater into clean water involved the combined use of multilevel filters and a 20% PES membrane ultrafiltration system.

The results of domestic wastewater treatment using the MSL method using HLR variations on total coliform from 1.89  105 MPN/100mL to 6.0  102 MPN/100mL, the total colony parameter from 5.95  106 CFU/mL to 3.6  105 CFU/mL, the chemical oxygen demand parameter value of 53 mg/L with an effectiveness of 98.6%, the total suspended solid parameter is valued at 25 mg/L with reduction effectiveness of 98.6% and the pH value changes to 7.3 at the HLR variation of 3.40 L/m2/hour. As for using the HRT variation for 12 hours the total coliform from 1.16  104 MPN/100mL to 9  102 MPN/100mL, the total colony parameter from 4.91  106 CFU/mL to 3.0  105 CFU/mL, the chemical oxygen demand parameter was 92 mg/L with its effectiveness 99%, the total suspended solid parameter is 87 mg/L with reduction effectiveness of 67% and the potential of hydrogen value changes to 7.6. Therefore, the MSL method employing bio rings can be used as a new option for domestic effluent treatment. Keywords: domestic wastewater, coliform total, Multi Soil Layering (MSL)  ABSTRAK Penelitian ini menggunakan Multi Soil Layering (MSL), sebuah teknologi ramah lingkungan, untuk menghilangkan kontaminan bakteri coliform dari air limbah menggunakan media alternatif baru.
