Abstract

Hazardous and toxic waste (B3 waste) management in higher education environments isimportant to prevent environmental pollution and health risks caused by improper wastehandling. Campus operational activities, laboratories, ofces, and facility maintenance activitieshave the potential to generate various types of hazardous waste that require proper managementaccording to environmental regulations. This study aimed to identify the types, characteristics,sources, and generation of B3 waste produced at Campus X. The research used a descriptiveobservational method through direct eld observations, waste generation measurements forseven consecutive days, documentation, and short interviews during the observation process.The results showed that hazardous waste generated at Campus X originated from laboratoryactivities, ofce activities, campus operational activities, and equipment maintenance. Theidentied waste types included electronic waste, used batteries, expired chemicals, infectiouswaste, uorescent lamps, and used hazardous waste packaging. The total hazardous wastegeneration during the observation period reached 57.53 kg with an average generation of 8.22kg/day. Most of the waste characteristics were classied as toxic, corrosive, infectious,ammable, and environmentally hazardous. The study also found that hazardous wastesegregation and temporary storage practices at Campus X were still not fully implementedaccording to technical standards. Therefore, improvements in waste segregation systems,provision of temporary storage facilities, and strengthening of hazardous waste managementpractices are necessary to support environmentally sustainable campus management.

Abstract

Mangrove ecosystems play an essential ecological role in coastal environments by stabilizing sediments and trapping various pollutants, including microplastics. Increasing plastic waste generated by human activities has contributed to the accumulation of microplastics in coastal ecosystems, particularly within mangrove sediments. This study aimed to analyze microplastic abundance in mangrove sediments based on mangrove density in the mangrove area of Cemara Beach, Puger, Jember. Sediment sampling was carried out at four observation points representing different environmental characteristics and levels of human activity, namely tourism areas, residential areas, central mangrove zones, and areas remote from human activities. Microplastic abundance was determined by calculating the number of particles identified in each sediment sample and expressing the results as particles per gram of sediment. The findings revealed that microplastics were present at all sampling locations with a total abundance of 0.885 particles/gram. The highest abundance was recorded at the residential area (0.650 particles/gram), while the lowest abundance was found at the site far from human activities (0.019 particles/gram). Mangrove density varied among observation points and contributed to sediment retention; however, microplastic abundance was not determined solely by vegetation density. Human activities, particularly those related to settlements and tourism, appeared to play a substantial role in increasing microplastic inputs into the mangrove ecosystem. These findings highlight the ecological function of mangroves as natural traps for microplastics and emphasize the need for improved coastal waste management and mangrove conservation to reduce microplastic contamination in coastal environments.
