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

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

An increase in slaughtering animals will have an impact on increasing the liquid waste produced. The resulting RPH liquid waste can damage the environment if it is not treated, so it is necessary to conduct research to reduce pollutant levels so that it is suitable for disposal into the environment. The technique used in processing RPH wastewater is iron sand filtration method. Iron sand filtration is a filtering process using renewable media, namely iron sand. Iron sand is known to contain the mineral magnetite (Fe3O4) which has the ability to absorb colloidal solids, so it has the potential to be used to remove pollutant content of RPH liquid waste. This research objective to determine the effect of variations in the thickness of the filtration media (cm) and grain size (mesh) on pollutant parameters. The thickness variations used were 20, 25, and 30 cm, with grain sizes of iron sand 40, 60 and 100 mesh. The experimental results showed that the iron sand filtration method was able to reduce Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) levels, increase the Dissolve Oxygen Meter (DO) value, and change the pH value. The highest reduction in COD was in the thickness variation of 30 cm with 100 mesh. the percentage of decrease in the value of Chemical Oxygen Demand (COD) was 95.05%, the highest decrease in Total Suspended Solid (TSS) value was in the media thickness variation of 30 cm with 100 mesh, the percentage of TSS value reduction was 97.11%, the pH value increased in the thickness variation media 30 cm with a mesh number of 100 from 5.8 to 7.4, and the value of Dissolve Oxygen Meter (DO) increased with variations in thickness of 30 cm with 100 mesh, increased from 1.2 to 15.2. Based on the parameter test results, it was concluded that iron sand filtration is effective in reducing pollutant levels below the quality standard, so that it is expected to be applied directly on a larger scale.

Abstract

Even though phytoremediation is considered a green technology for remediating heavy metals, there are some problems with the application of this technology, particularly when it comes to managing the biomass that is used. So, processing biomass needs to be given a lot of attention. This study outlined the utilization of extracts obtained from the hyperaccumulator plant Brassica oleracea var. alboglabra to synthesize nickel oxide nanoparticles. Subsequently, the nanoparticle underwent testing to determine its suitability as an absorbent for heavy metals, specifically lead, as well as its efficacy as an antifungal agent against Fusarium sp. strain. The characterization of nickel oxide nanoparticles involved several measurements, such as scanning electron microscopy analysis, high- and low-resolution transmission electron microscopy, energy dispersive spectroscopy, X-ray diffraction, and hysteresis curve acquisition. The research findings indicate that the extract from hyperaccumulators can be utilized for the synthesis of NiO, which exhibits an absorption capacity exceeding 98% and serves as an efficient antifungal agent against Fusarium sp. pathogens. The approach utilized in this study not only prioritizes "green" and sustainability factors but also takes into account the economic aspects associated with the items being manufactured. The research has important implications in two areas. Firstly, it demonstrates the utilization of natural resources (B. oleracea var. alboglabra) in the production of nickel oxide, which serves as a safer and more eco-friendly substitute for dangerous chemicals. Furthermore, it aids in the advancement of novel techniques for effectively managing biomass hyperaccumulators.
