Abstract

Plastic waste has become one of the major problems threatening the environment and human healthIn Indonesia, the use of plastics in daily life, such as shopping bags, water bottles, and food packaging, contributes greatly to the increasing amount of plastic waste (Ditjen PPKL, 2018). This research aims to analyse effective plastic waste management strategies to reduce negative impacts on the environment. The research uses a mixed-method approach, a combination of quantitative and qualitative methods, to gain a comprehensive understanding of the condition of plastic waste and identify the factors that influence the effectiveness of such management. This method is relevant for evaluating waste management policies, the role of the community, and the application of environmentally friendly technologies. This study will be conducted in several areas that have high plastic waste production rates, such as urban, coastal, and areas with community-based waste management initiatives. The results show that community awareness level participation in recycling high 60% p = 0.001 This shows that environmental education is very important to increase community participation. Community-based education is needed to raise this awareness. A massive education campaign is needed, involving community leaders to strengthen positive social norms.

Abstract

Diarrhea remains a leading cause of morbidity and mortality among children under five, especially in developing countries like Indonesia. Contaminated water that fails to meet physical and microbiological standards significantly contributes to disease transmission in children. This study employed a quantitative, observational analytic cross-sectional design to examine the relationship between well water quality and childhood diarrhea incidence in southern coastal areas. A total of 100 households with children aged 1-5 years, relying on well water for drinking, participated. Univariate analysis described respondent characteristics and water quality, while chi-square tests assessed associations between well water quality and childhood diarrhea incidence. Bivariate and multivariate logistic regression analyses determined risk magnitudes (odds ratios). The findings indicated a significant association between microbiological contamination of household well water and diarrhea occurrence in children (p = 0.001; OR = 4.00). Additionally, wells located less than 10 meters from septic tanks posed a higher risk (OR = 2.67). Although differences in well type (dug vs. drilled) were observed, they were not statistically significant (p = 0.202). These results indicate that poor well water quality is a major risk factor for diarrhoea in children in the southern coastal region. To reduce this risk, public health efforts need to focus on improving access to clean water, environmental sanitation education, and technical supervision in the construction and maintenance of wells. This integrated approach is important for reducing the incidence of diarrhoea in children and improving the health status of children in affected communities.

Abstract

Waste management has emerged as a critical environmental issue, particularly in rural areas where population growth and changing consumption patterns have led to increased waste generation. This research focuses on the implementation of community-based waste management in villages, aiming to understand its impact on environmental health and the factors influencing program success. Utilizing a quantitative analytic approach with a cross-sectional research design, the study surveyed 4,345 family heads, with a sample size of 98 participants.The findings revealed that 54.1% of respondents did not engage in waste management activities. Among these non-participants, 70.4% had low educational attainment (elementary or junior high school). Additionally, 53.1% cited a lack of infrastructure as a barrier to participation, while 64.3% reported poor knowledge of waste management practices.The results indicated that infrastructure availability significantly influences community participation, with a p-value of 0.006 and an odds ratio (OR) of 3.911. Furthermore, knowledge levels were crucial; those with inadequate knowledge were less likely to participate (69.2% did not engage), whereas those with good knowledge showed higher participation rates (63%).Effective waste management is essential for improving environmental health by reducing pollution and disease risks. Therefore, enhancing education and infrastructure is vital to encourage community involvement in waste management initiatives. This study underscores the importance of addressing knowledge gaps and infrastructural challenges to foster sustainable waste management practices in rural communities.
Utilization of Natural Adsorbents (Rice Husk, Charcoal) in Drinking Water Treatment to Reduce Heavy Metal and Microorganism Content Lieza Corsita

Abstract

Access to clean drinking water is a fundamental human right, yet millions face contamination from heavy metals and pathogens. This study evaluated the efficacy of natural adsorbents raw rice husk (RH), rice husk ash (RHA), and activated carbon (AC) for treating contaminated water. The adsorbents were prepared, characterized, and tested in batch experiments. Characterization via SEM, FTIR, and BET revealed that activation significantly enhanced properties; AC exhibited the highest surface area (732.5 m²/g) and porosity, followed by RHA and RH. Under optimized conditions (pH 6-7, dosage 2 g/L, contact time 60 min), AC demonstrated superior removal efficiencies for Pb²⁺ (92.6%), As³⁺ (88.4%), and F⁻ (75.1%). Adsorption data best fit the Langmuir isotherm and pseudo-second-order kinetic model, indicating monolayer chemisorption. However, microbial removal was limited (<30% for E. coli), underscoring the need for complementary disinfection. Regeneration studies showed AC maintained >80% efficiency after three cycles. The findings confirm that activated carbon is highly effective, while rice husk ash is a viable low-cost alternative for heavy metal and fluoride removal. For comprehensive water safety, integrating these adsorbents into hybrid treatment systems is recommended.
