Acid mine drainage (AMD) is one of the major environmental problems arising from coal mining activities. AMD is formed through the oxidation of sulfide minerals, resulting in acidic water with high concentrations of dissolved heavy metals. This condition is characterized by elevated levels of Fe, Mn, and total suspended solids (TSS), which, if left untreated, can pollute nearby water bodies, damage aquatic ecosystems, and pose risks to human health. Therefore, effective, eco-friendly, and low-cost treatment methods are needed to minimize the negative impacts of AMD. This study aims to investigate the effect of activated carbon derived from sugarcane bagasse as an adsorbent for reducing Fe, Mn, and TSS levels in AMD at the sump of PT Alreksa Bara Mitra. The selection of sugarcane bagasse is based on its abundance as an agro-industrial waste and its high lignocellulosic content, making it a potential raw material for activated carbon. The research involved the preparation of activated carbon through carbonization and activation processes, followed by its application to AMD samples with variations in adsorbent dosage and contact time. Laboratory analyses were conducted to measure the concentrations of Fe, Mn, and TSS before and after treatment. The results showed that sugarcane bagasse-based activated carbon significantly reduced Fe, Mn, and TSS concentrations. The highest removal efficiencies were achieved under optimum conditions, reaching 93.14% for Fe, 95.05% for Mn, and 85.04% for TSS. These findings demonstrate that activated carbon from sugarcane bagasse has a strong adsorption capacity for dissolved metals and suspended solids in AMD. In conclusion, sugarcane bagasse-derived activated carbon has potential as an environmentally friendly and cost-effective alternative for AMD treatment, while simultaneously providing added value to agro-industrial waste. This research is expected to serve as a reference for the development of more sustainable mine wastewater treatment methods.

This research was carried out using a qualitative method through a direct survey conducted in Tangga Batu Village. The main goal of this study is to utilize corn cob waste into an alternative fuel product in the form of briquettes that is more environmentally friendly. Corn cobs are one of the abundant agricultural wastes, but they are often not used optimally. Through simple innovations, this waste can be processed into alternative energy sources that have economic value while having added value for the surrounding community. The process of making briquettes begins with the preparation of equipment which includes a kiln, mold, drying container, mash tool, strainer, and scale. The main ingredient is corn cobs that are first dried in the sun for 3–4 days to reduce the moisture content by 10–20%. Additional materials used are tapioca flour as an adhesive, small amounts of diesel, and water. The next stage is to compose the corn cobs in the burning pit for 20–30 minutes until they become charcoal. The charcoal is then scraped using a simple tool and sifted to separate the fine and rough parts. The fine charcoal is mixed with a starch adhesive from tapioca flour, then molded using a simple mold and compacted through a pressing process to produce good quality briquettes. Next, the briquettes are dried in the sun for 2-3 days until they are completely dry and ready to be used as fuel instead of wood or kerosene. The results of the study show that corn cob waste has great potential to be used as an alternative fuel. In addition to being environmentally friendly, these products also contribute to reducing dependence on fossil fuels.

The use of palm oil waste as boiler fuel is one of the innovative solutions in supporting the use of renewable energy while reducing the environmental impact of palm oil industry waste. Waste such as palm shells, mesocarp fibers, and empty oil palm bunches have high energy potential through direct combustion and other thermal technologies. This study aims to evaluate the potential use of palm oil waste as boiler fuel based on its calorific value, combustion efficiency, and environmental impact. The methods used include analysis of the physical and chemical characteristics of waste, boiler performance tests, and exhaust gas emission evaluation. The results show that palm oil waste has a high calorific value (15–20 MJ/kg), which makes it an efficient alternative fuel. In addition, the use of this waste is able to reduce dependence on fossil fuels while minimizing carbon emissions, thereby supporting the greenhouse gas emission reduction target. From an operational perspective, the use of palm oil waste in industrial boilers can increase combustion efficiency by up to 75–85%, depending on fuel conditions and boiler design. This makes palm oil waste not only economically valuable, but also strategic in supporting the transition to clean energy. Another advantage is that waste management becomes more targeted, because solid waste that is usually only an environmental burden can be reused as an energy source. However, some of the challenges that need to be considered include relatively high ash levels, the potential for corrosion in boiler equipment, and the need for emission control technology to comply with environmental standards. With the right mitigation strategy, palm oil waste can be processed into sustainable and environmentally friendly energy.

Sangatta Central Market, one of the largest trading centers in North Sangatta, accommodates more than 750 traders and operates daily until midday, reflecting the high intensity of economic transactions in the region. Within this trading environment, Islamic business ethics play a pivotal role, particularly for Muslim traders, as they not only regulate commercial practices but also shape customer comfort and satisfaction. However, observations indicate that not all traders consistently practice ethical behaviors in line with Islamic values—for example, some neglect to maintain a friendly attitude such as smiling during interactions with buyers. This condition potentially reduces the quality of service and impacts consumer willingness to return. In response, this study seeks to analyze the influence of Islamic business ethics on consumer purchasing interest at the North Sangatta Central Market. The research adopts a quantitative approach by distributing structured questionnaires to a sample of 96 Muslim customers, complemented by direct observation and systematic data recording. The collected data were analyzed using simple linear regression to determine the extent to which the implementation of Islamic business ethics contributes to consumers’ willingness to shop. The results reveal a regression equation of Y' = 9.764 + 0.304X with a correlation coefficient (R) of 0.299. The coefficient of determination (R²) of 29.9% indicates that Islamic business ethics significantly and positively influence consumer purchasing interest. In other words, nearly one-third of the variance in customer purchasing interest can be explained by the level of ethical business practice applied by traders. This finding implies that the more traders integrate Islamic values—such as honesty, fairness, and friendly interaction—into their daily business practices, the more likely consumers are to engage in transactions and maintain loyalty to the market.

This study investigates the potential of Low-Density Polyethylene (LDPE) plastic waste as a partial substitute for sand in concrete block mixtures, focusing on its effects on compressive strength and water absorption. LDPE is a non-biodegradable plastic waste that poses significant environmental challenges. Its incorporation into construction materials offers a promising solution to reduce pollution while enhancing the performance of building components. The research employed LDPE substitution levels of 10%, 15%, 20%, 25%, and 30% by weight of sand, compared against conventional concrete blocks without LDPE. Experimental results revealed that the highest compressive strength was achieved with a 15% LDPE mixture, reaching 80.762 kg/cm² at 28 days of curing—an increase of approximately 40.8% compared to normal blocks, which recorded 57.359 kg/cm². LDPE additions up to 20% maintained favorable strength characteristics, while higher proportions (25% and 30%) led to a decline in mechanical performance. In terms of water absorption, the inclusion of LDPE demonstrated a decreasing trend, attributed to the hydrophobic nature of plastic, which enhances moisture resistance in the concrete blocks. These findings suggest that a 15% LDPE substitution represents an optimal formulation for producing eco-friendly concrete blocks with improved strength and reduced water absorption. The study highlights the dual benefits of waste management and material innovation, aligning with sustainable development goals. By repurposing plastic waste into construction applications, this approach not only mitigates environmental impact but also contributes to the advancement of green building technologies. Further research is recommended to explore long-term durability, thermal properties, and scalability of LDPE-based concrete products in real-world construction settings.

This study uses the library research qualitative method to examine the effectiveness of economic incentives in encouraging the conservation of natural resources (SDA) as well as mitigating environmental damage in a sustainable manner. The background of this study is driven by the increasing environmental degradation due to uncontrolled exploitation of natural resources, which is often oriented towards short-term profits without regard for ecological sustainability and community welfare. In this context, economic incentives are seen as a strategic policy instrument that is able to influence the behavior of business actors and society towards a more environmentally friendly and socially responsible activity pattern. Various forms of economic incentives were discussed including green subsidies, environmental taxes, payment for environmental services (PES) schemes, and ecolabel certification. These instruments are considered to be able to internalize the external costs of environmental damage into economic calculations, thereby providing pressure and motivation for business actors to implement more sustainable and innovative practices. Based on a review of academic literature, scientific journals, as well as national and international policies, it was found that the implementation of economic incentives has proven to be effective in increasing environmental awareness and encouraging green innovation significantly. However, the effectiveness of its implementation is highly dependent on the quality of policy governance, the level of transparency, regulatory clarity, and the active involvement of local communities. Without adequate oversight, incentives have the potential to be abused or not achieve their intended goals. Therefore, the design of economic incentive policies must be fair, measurable, and prepared with a participatory approach and based on empirical data. This study concludes that economic incentives not only function as a financial mechanism, but also as an instrument of behavior change, economic culture, and environmental innovation towards sustainability.
