Abstract

Background: Plastic debris smaller than 5 mm is categorized as microplastic, a pollutant with persistent characteristics that often contains toxic or carcinogenic compounds. These particles can infiltrate soil systems, migrate into the food chain, and ultimately threaten both environmental integrity and human health. This research focuses on identifying the types and quantifying the abundance of microplastics in soils collected from three final disposal sites in Lampung Province, Indonesia. Methodology: Sampling at three landfill points was carried out purposive sampling method, with microplastics sample analyzed through visual inspection by microscopy and polymer composition confirmed using Fourier Transform Infrared (FTIR) Spectroscopy Method. Findings: Landfill sites B1 and C1 exhibited the highest abundance of microplastics, reaching 195 particles per kilogram of soil. The particles displayed morphological diversity, including fragments, fibers, and films, with fragments representing the predominant category. The color distribution was largely transparent, black, and brown, while the detected particle sizes ranged from 2.12 to 110.25 μm. Polymer analysis revealed the presence of polyethylene (PE), polyamide, and polystyrene, alongside particles suspected to be polyethylene terephthalate (PET). These findings indicate that physical and chemical degradation processes accelerate the breakdown of plastics into smaller fragments, thereby contributing to elevated microplastic levels in landfill soils. Contribution: The outcomes of this research, derived from visual microscopy and FTIR Spectroscopy-based identification of microplastics in Lampung landfill soils, The findings offer essential data for the development of monitoring frameworks and risk assessment strategies related to soil and environmental risks in the region

Abstract

Leachate is residual waste that is exposed to water when it rains. Leachate contains physical, chemical and biological parameters that are dangerous if it enters the canals and residential areas of residents. Many problems will arise if the leachate is not treated and left alone. The purpose of this study was to determine the amount of leachate pollution on the environmental health of settlements at the Bakung final disposal site in Bandar Lampung. This type of research is qualitative research and is presented descriptively. The test sample was taken using the composite sample method (combined place) at three pool points, each of 1.7 liters with a total of 5 liters and homogenized. Samples were analyzed using SNI 8995:2021 and the water quality was assessed using the Pollution Index (IP) method. To find out the health of the environment using interviews with the community around the final disposal site. The results of the analysis showed that the physical and chemical parameters of leachate at Bakung landfill that exceeded the leachate quality standards were TSS (538.33 mg/L), BOD (5382 mg/L), COD (8220 mg/L), Total Nitrogen (91 mg/L). If the leachate is only collected without further treatment, it will result in the leachate entering residential canals and contaminating the well water in the surrounding area and possibly causing health problems such as skin irritation. Toxic environment, water unfit for consumption evenblue baby syndrome in infants and an increased risk of colon cancer.

Abstract

Differentiated instruction has been a focus among educators since the emergence of the Merdeka Curriculum. This approach is recognized as a fundamental strategy in facilitating student-centered learning by aligning instructional methods with their diverse learning needs. However, teachers in schools with limited resources still encounter challenges in effectively implementing differential learning. Therefore, this community empowerment initiative aims to enhancing the teaching community in school mover to design and implement differential learning effectively. The Asset Based Community Development (ABCD) approach serves as the guiding framework for this empowerment, facilitating teacher training in the design, implementation, and evaluation of differential learning strategies. This initiative is manifested through various collaborative activities, including workshops, group discussions, share best practices, and collective reflection within the school's teaching community. The result of this empowerment initiative demonstrate that collaborative approach can significantly enhance teacher competence in developing and implementing differentiated instruction. Therefore, this empowerment model holds the potential for broader adoption within other educational communities, thereby extending its positive impact on enhancing the quality of learning processes.

Abstract

Elephants are charismatic exotic animals. As the largest land animal on the earth, their maximum weight can reach more than 7 tons and 4 meters in height. Apart from their exoticness, however, elephants, particularly Asian elephants are now losing more than 70% of their habitat. As a result, the International Union for Conservation of Nature (IUCN) has red-listed Asian elephants as the critically endangered animal. Various conservation efforts have been implemented, such as translocation of the elephants, control of poaching, educational campaigns, and research. Nonetheless, over the past two decades, Elephant Endotheliotropic Herpesvirus (EEHV), a newly emerging disease has caused a serious threat to Asian elephants’ health worldwide. The virus causes a rapid, acute, and fatal haemorrhagic disease as the major clinical manifestation in adult Asian elephants and particularly in juvenile elephants in both wild and captive populations. This article provides a literature review regarding the EEHV infection in Asian elephants.

Abstract

Eco-enzyme solutions are commonly utilized as disinfectants, cleaners, and liquid fertilizers; however, their potential as substrates for biogas production remains underexplored. This study evaluated the methane (CH₄), carbon dioxide (CO₂), nitrogen (N₂), pH, temperature, and gas pressure generated from eco-enzyme–based anaerobic fermentation supplemented with cow manure as a microbial starter. A quantitative experimental design with five treatments and direct observational measurements was employed, and data were analyzed descriptively. Results showed that methane production was generally low, with the highest concentration observed in treatment P5 (2.889%). The highest gas pressure was also recorded in P5 (70 mL). Nitrogen dominated the gas composition (95.875–99.669%), while CO₂ ranged from 0.237 to 4.125%. These findings indicate that eco-enzyme combined with cow manure produces low CH₄ levels, suggesting that further optimization of substrate composition and fermentation conditions is needed to enhance biogas quality.

Abstract

Microplastics pose serious threats as they can  contaminate various ecosystems, ranging from seawater surfaces, beach sands, freshwater sediments, coastal sediments, to deep-sea environments. Their presence, particularly in coastal areas, exerts significant negative impacts on ecosystem balance and human health. This study aimed to analyze the types and abundance of microplastics in seawater and sediments of South Lampung’s coastal area, measure related environmental parameters (BOD, COD, pH, temperature, and current velocity), and provide baseline data to support strategies for pollution control. The research was conducted using an experimental method at six stations located 50–100 meters apart. Water and sediment samples were collected, filtered, separated, and analyzed using Fourier Transform Infrared Spectroscopy (FTIR) to identify polymer types. The results revealed that microplastics were detected at all stations, with dominant polymers including polyethylene (PE), polypropylene (PP), polyester (PES), polystyrene (PS), and smaller amounts of polyamide. Physico-chemical parameters of the waters were generally within acceptable thresholds, although BOD levels at several stations slightly exceeded the quality standards, indicating a relatively high organic load. This study confirms that microplastic pollution has already occurred in the South Lampung coastal area, dominated by polymers originating mainly from anthropogenic activities such as household waste, synthetic textiles, and coastal activities. As such, this research provides an essential initial step in mapping microplastic pollution in the region.
