Abstract

Aluminum black dross is produced by the secondary smelting process of aluminum. Aluminum black dross is classified as hazardous waste because it is reactive with water and produces substances and gases that are harmful to humans and the environment. Generally, aluminum black dross is managed by landfill method, but because it is produced in large amounts every year, the aluminum black dross needs to be utilized to reduce the impact on the environment. Aluminum black dross consists of large amounts of metal oxide and salts. The amount of metal oxide content in aluminum black dross can be used as raw material. This paper review types of processes for utilizing black dross aluminum as raw material in value-added products. aluminum black dross can be used as alumina, adsorbent, zeolite, composites, geopolymers, refractories, and fillers. By utilizing aluminum black dross waste into various products that have economic value, besides being able to protect the environment, it can also reduce environmental resource use.

Abstract

Acid mine drainage (AMD), produced when sulfide minerals are subjected to oxygen and water, is one of the major issues in mining industries. Without proper management, AMD's release to the environment would cause seriously prolonged environmental and health issues, such as increases soil acidity and reduces water quality due to extremely low pH, high sulphate concentration, and heavy metal solubility. AMD treatments are divided into two categories, i.e., active treatment, conducted by applying a chemical to the AMD to neutralize pH and precipitate heavy metals; and passive treatment, which relies on biological and biochemical processes. The active treatment may provide an immediate effect, but costly and yet sustainable; meanwhile, passive treatment takes time to establish and to generate an effect, but it is more economical, sustainable, and environmentally friendly. The wetland system is an example of passive treatment. Therefore, this review focuses on passive treatments, especially the selection of organic materials used in constructed AMD wetland treatment. Organic materials play a central role in the wetland system, i.e., to chelate metal ions, remove sulphate from the solution, increase pH, and growth media for microbes, especially sulphate reducing bacteria (SRB) and plants are grown in the system. Overall, organic materials determine the effectiveness of the wetland system to neutralize AMD passively and sustainably.

Abstract

The formation of acid mine drainage (AMD) is a common environmental problem in the mining industry. Its passive management through wetland construction has gained more consideration in recent years. However, the application in the field is constrained by the large area and relatively shallow depth. Indonesia has no passive technology to neutralize AMD in deep water. One solution is to apply a floating treatment wetland (FTW) system. Therefore, this study aimed to determine the ability of several hyperaccumulator plants, such as Melaleuca cajuputi, Nauclea orientalis, and Vetiveria zizanioides, to neutralize AMD using a floating system by conducting FTW trials. The method used was a Completely Randomized Design (CRD) with 3 treatments and control/without plants. Each treatment had 3 replications, resulting in 12 experimental units. The results showed that the FTW with or without plants could increase pH and decrease dissolved Mn by 75.31-90.74%. Heavy metals were chelated by organic matter, absorbed by plants, and deposited in the form of metal sulfides. The results also indicated that besides having a positive effect on pH and heavy metal reduction, the organic-based floating wetland increased biological oxygen demand (BOD) from 61.08-79.71%.

Abstract

Medical waste management is one of the important things in handling the Covid-19 pandemic. Depok City is one of the areas of West Java Province in Indonesia which in the spread of Covid 19 is in the 5 (five) highest positions. The purpose of this research is the management of infectious waste before and during the emergence of the Covid-19 pandemic. This study used a qualitative method. Stages of research is the identification of performance and assessment of the performance of the management of infectious waste using the Balanced Scorecard method, identification plan management strategies using the SWOT method and prioritizing the implementation of the strategy with the method Interpretative Structural Modeling (ISM). The results showed that the infectious waste generation at the Depok City Hospital during the Covid-19 pandemic increased to 2.75 tons per year. The hospital has made efforts to reduce and sort out, but the obstacles faced during the sorting process are the limited number of Personal Protective Equipment (PPE) so that it can increase the risk of transmitting Covid-19 to officers and the absence of cold storage in the Temporary Disposal of Hazardous and Toxic Materials. (TPS B3). The Depok City Regional General Hospital (RSUD) has collaborated with third parties who have permits from the government. The most influential strategy that can be carried out by hospitals is to improve waste management facilities and infrastructure and strengthen SOPs with waste management parties.

Abstract

The need for rice continues to increase along with the increase in population. Efforts to increase rice production is generally carried out through proper and balanced fertilization. Other than that, plant growth-promoting actinobacterial (PGPB) inoculants can be used as an alternative solution. This study aimed to examine the effect of the application of actinobacterial seed dressing and NPK fertilizers on the growth of rice plants grown in a glass house. A randomized block design with three factors was conducted, consisting of actinobacterial seed dressing (added and not added), type of carrier (zeolite, peat, and combinations) and doses of NPK fertilizer (0 g/pot, 0.375 g/pot, and 0.75 g/pot). The addition of actinobacteria consortium, peat-zeolite combination 1:3, and NPK fertilizer at a dose of 0.75 g/pot (A2C3P3) gave consistent results in increasing the average yield of rice vegetative and reproductive parameters observed in the glass house. The A2C3P3 treatment had a significant effect on the number of tillers, width of flag leaf, dry weight of roots and shoots of rice observed at 10 WAP compared to other treatment combinations. The actinobacterial seed coating plays a pivotal role in supporting rice plant growth.

Abstract

Zeolite is known as a cation exchange adsorbent and has high adsorption capabilities. These two functions of zeolite have the opportunity to be a solution in dealing with cationic dye waste. The aim of this research was to determine the CEC value and adsorption capacity of zeolite in adsorbing methylene blue. Zeolite powder is made using local metakaolin and added NaOH or water glass using the hydrothermal method. The powdered zeolite product obtained was mixed with geopolymer to form a composite of small granules and large granules. The results of XRD characterization of the synthetic product obtained from a mixture of metakaolin and NaOH were NaA zeolite, while the addition of water glass resulted in NaX zeolite. Zeolite in powder form or geopolymer-zeolite granule composite shows a high cation exchange capacity (CEC) above 200 cmol/kg. The methylene blue adsorption test on each adsorbent showed that the adsorption capacities of NaA zeolite, NaX zeolite, NaA geopolymer-zeolite small granule and large granule composites, and NaX geopolymer-zeolite small granule and large granule composites were respectively 30.81 mg g-1, 32.84 mg g-1, 53.29 mg g-1, 51.64 mg g-1, 38.32 mg g-1, 54.22 mg g-1 and 48.81 mg g-1.

Abstract

Zinc deficiency is a major health issue in developing nations, especially in Southeast and South Asia. To address this, food fortification using nanotechnology, such as ZnO nanoparticles deemed safe by the US FDA, can enhance daily zinc intake essential for growth and immune health. This research emphasizes on yoghurt fortification with various types: ZnO nanoparticle fortification and the addition of probiotic bacteria Lactiplantibacillus plantarum subsp. plantarum IIA-1A5 (Accession Number: OR473281) and aims to analyze the nutritional value, characteristics, total lactic acid bacteria (LAB) and antibacterial activity of probiotic yogurt fortified with ZnO nanoparticles. There were six levels of treatment designed in this study and each treatment was tested three times. The statistical test used in analyzing the nutritional value, characteristics, total LAB and antibacterial activity in this study is the Tukey test which is applied as a multiple range test while in organoleptic testing using the Kruskal-Wallis non-parametric test. The results showed that the fortification of yogurt with ZnO nanoparticles had significant interaction (p<0.05) on yogurt viscosity, LAB content, and color attributes in hedonic quality test. The antibacterial activity towards Staphylococcus aureus and Escherichia coli produced by six treatments were moderate, with inhibition zones ranging between 5 to 10 mm. This study concluded that the fortified yoghurt treatment met the Indonesian National Standard (SNI), demonstrating the potential of this approach in addressing zinc deficiency in at-risk populations. This research underscores the promise of nanotechnology in food fortification strategies to combat micronutrient deficiencies globally
