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

A synthetic zeolite was produced from natural zeolite from Ende-Nusa Tenggara Timur (NTT) by hydrothermal method. This study aims to produce synthetic zeolite from Ende natural zeolite to remove cation dye through the adsorption process. Temperature of crystal formation (ageing) was performed at 60 °C for 6 h and hydrothermal process was at 100 °C for 24 h. The natural zeolite produced synthetic NaP1 and synthetic Faujasite. Based on the research results, the synthesis of zeolite by the hydrothermal method can enhance the adsorption capacity and Cation Exchange Capacity (CEC). The adsorption capacity in the natural zeolites of type ZG, ZL and ZC before the hydrothermal process were 17.289, 17.276, and 16.483 mg/g, respectively, and after hydrothermal they increased to 37.398, 37.369 and 37.362 mg/g, respectively. In addition, the CEC increased from 84.154, 81.042, and 77.474 cmol/kg, respectively, to 244.063, 216.354, and 211.432 cmol/kg, respectively. The Langmuir model most closely matched the isothermal adsorption equilibrium process.

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

The excessive use of antibiotics to treat bacterial infections can lead to bacterial resistance, necessitating other antibacterial agents as alternatives. This research combined charcoal and activated charcoal with metal oxide, namely copper oxide (Cu2O), which has antibacterial properties against Gram-positive and Gram-negative bacteria, thus producing an antibacterial composite for water treatment processes. Furthermore, this study also examined the effect of different types of sugar as reducing agents on the produced Cu2O and identified the antibacterial activity of Cu2O and its composites. Synthesis of Cu2O through the Tollens-like reaction method using Cu(NO3)2 as a precursor, then adding NaOH, NH4OH, and sugar. The sugars were sucrose, white sugar, and brown sugar. The type of sugar used as a reducing agent affected the size and morphology of the Cu2O produced. Adding Cu2O to charcoal and activated charcoal increased antibacterial properties to charcoal and activated charcoal. Copper oxide, Cu2O/charcoal, and Cu2O/activated charcoal exhibited high antibacterial properties against Escherichia coli (Gram-negative), as of 5.69 ± 0.02 mm and 6.23 ± 0.03 mm, respectively, due to their thinner cell walls compared to Staphylococcus aureus (Gram-positive). The Cu2O synthesized using white sugar as the reducing agent showed the best antibacterial activity, with an 8.26 ± 0.19 mm inhibition zone. Keywords: activated charcoal, antibacterial, charcoal, copper oxide, sugar

Abstract

This study develops roselle yogurt ice cream by combining the probiotic benefits of yogurt with bioactive compounds from roselle flowers. Yogurt is produced through milk fermentation by lactic acid bacteria, while roselle flower extract is rich in anthocyanins and flavonoids known for their antioxidant, antibacterial, and anti-inflammatory properties. The research methods included a comprehensive analysis of physicochemical properties, nutritional content, microbiology, antioxidant activity, and organoleptic characteristics. Using a randomized complete design, data analysis employed ANOVA and the Least Significant Difference tests (P < 0.05), with sensory evaluation conducted using the Kruskal-Wallis test. The results of exploring the synergy between roselle yogurt and ice cream in varying proportions (20:80, 30:70, 40:60) showed that the treatment with a 30:70 ratio of roselle yoghurt (P2) was optimal in physicochemical characteristics such as pH 5.47, total titratable acidity 0.74%, overrun 75.61%, and meltdown rate of 26.98 minutes. P2 also exhibited the highest total antioxidant activity at 137 µg/mL, with good sensory acceptance from consumers. This experiment provided an understanding of the potential of roselle yoghurt ice cream as a product that meets increasingly selective consumers' nutritional and health needs. It is hoped that these findings will stimulate the development of ice cream products that are not only commercially popular but also provide significant health benefits. Keywords: roselle yoghurt ice cream, antioxidant activity, consumer health

Abstract

Laboratory waste represents a growing global concern due to its potential impacts on environmental quality, human health, and safety when improperly managed. At IPB University, laboratory activities generate up to 5 tons of wastewater per month, emphasizing the need for effective and sustainable waste management strategies. This study proposes a structured gap-to-roadmap framework for independent chemical waste management in testing and calibration laboratories. The framework integrates criteria-based gap analysis, a literature-derived waste minimization checklist, and phased implementation planning. Data were collected through semi-structured interviews and literature review and analyzed using a qualitative, criteria-based approach. The results indicate that the PPLH IPB Laboratory generates approximately 100–481 L of chemical waste annually. While several minimization practices have been implemented, key gaps remain in standard operating procedures, labeling systems, temporary storage, and recovery and recycling practices. The checklist analysis further identifies feasible strategies, including solvent recycling and inter-laboratory chemical exchange, with significant potential for waste reduction and improved resource efficiency. The proposed framework translates identified gaps into targeted actions and assigns them into short-, medium-, and long-term implementation phases. This approach provides a practical and replicable tool for laboratories seeking to transition toward independent, compliant, and environmentally sustainable waste management systems, particularly in resource-constrained settings.
