Abstract

The increasingly rapid development of industry can cause environmental pollution from the wastewater produced. Industrial wastewater contains heavy metal ions, one of which is iron (Fe). The danger of Fe metal can have a negative impact on living things and the environment so it needs to be minimized and eliminated. Adsorption has been proven to be an effective method in reducing the levels of heavy metal ions in waste. In the adsorption process, the most important thing is the adsorbent. Allophane and quartz sand are natural materials that can be used as adsorbents. This study is expected to determine the adsorbent capacity of allophane and quartz sand against iron (Fe) metal ions. The adsorption process was carried out in 2 variations, namely variations in the mass composition of the adsorbent (0:100; 25:75; 50:50; 75:25; 100:0) and variations in contact time (15, 30, 60, 90, 120). Measurement of adsorption capacity using Atomic Absorption Spectroscopy (AAS). The results showed that the optimal results for variations in the mass composition of allophane and quartz sand adsorbents were 50:50 with an adsorption capacity of 0.81325 mg/g and an absorption percentage of 67.67%. The optimal contact time was 60 minutes with an adsorption capacity of 0.81677 mg/g and an absorption percentage of 67.97%. This study showed that a mixture of allophane and quartz sand can be used as an effective adsorbent for the adsorption of heavy metal iron (Fe).

Abstract

Plastic pollution, particularly microplastics, is a global environmental issue with far-reaching impacts on ecosystems and human health. This review examines the effects of plastics across various ecosystems in Indonesia, including marine, riverine, mangrove, terrestrial, livestock, and human systems. Findings reveal that microplastics are present in fish, zooplankton, corals, and in marine and mangrove sediments. In rivers, plastics contribute to declining local fish populations and hormonal disorders. On land, microplastics inhibit plant growth, disrupt soil structure, and have been detected in chickens and ducks. For humans, microplastic consumption in Indonesia reaches approximately 15 grams per month, with particles detected in the gastrointestinal tract and daily consumables. Such exposure may cause allergic reactions, cell damage, and chronic diseases. These findings highlight that plastic pollution in Indonesia is not only an environmental problem but also a significant public health threat.

Abstract

Madiun City produces approximately 45,000 tons of waste per year, most of which ends up in the Winongo Final Disposal Site (TPA), while a small portion is processed through the community-based waste bank program. Waste banks play a role in reducing waste generation while providing economic value to the community through waste sorting and recycling. This study aims to analyze the effect of community participation on the sustainability of the Mojo Makmur Waste Bank in Mojorejo Subdistrict, Madiun City. The study used a quantitative approach with a sample of 10 waste bank members, data collected through questionnaires and analyzed using multiple linear regression. The results show that community participation through economic benefits, social factors & motivation, and environmental knowledge & education significantly affects the sustainability of the waste bank with an R² of 0.892. In conclusion, active involvement of the community is a key factor in ensuring the sustainability of the Mojo Makmur Waste Bank in Mojorejo Subdistrict, Madiun City.
