Abstract

Waste management remains a serious environmental issue, including in Tobek Godang Village, Pekanbaru. The lack of community awareness in separating organic, inorganic, and hazardous waste has resulted in suboptimal household waste management practices. This community service program aims to improve residents’ understanding and skills in waste separation and processing through socialization and training activities. The methods applied consisted of a questionnaire survey with 66 respondents, field observations, group discussions, and hands-on composting practice as part of a participatory approach. The results indicate an increase in community awareness, demonstrated by the provision of separate bins for organic and inorganic waste, better understanding of plastic recycling codes, and the ability to produce quality compost characterized by loose texture, dark color, and earthy aroma. The program’s sustainability is reflected in the community’s commitment to consistently apply environmentally friendly practices, potentially creating a multiplier effect in household-based waste management. Thus, this program can serve as a model of community empowerment in supporting environmental cleanliness and the achievement of local SDGs

Abstract

Nasopharyngeal carcinoma is a malignancy of the nasopharyngeal epithelium that is often diagnosed at an advanced stage and is associated with impaired immune regulation in the tumor microenvironment. T-cell immunoglobulin and mucin domain-3 (TIM-3) is an immune checkpoint molecule that plays a role in suppressing the antitumor immune response. This study aims to analyze the relationship between TIM-3 immune response expression and the histopathological type of nasopharyngeal carcinoma. An analytical study with a cross-sectional design was conducted on 40 paraffin blocks of nasopharyngeal carcinoma patients at H. Adam Malik General Hospital, Medan, selected by consecutive sampling. TIM-3 expression was analyzed using real-time polymerase chain reaction (RT-PCR) with the calculation of ΔCT values against the control gene β-actin. Univariate analysis was used to describe the characteristics of the subjects, while bivariate analysis used the Kruskal–Wallis test to assess the relationship between TIM-3 expression and histopathological type. The majority of subjects were male (65%) with a mean age of 48.2 ± 11.1 years. The most common histopathological type was non-keratinizing squamous cell carcinoma (90%). The mean TIM-3 expression was 4.3 ± 1.6 with a median of 4.8 (−0.1–6.7), and 97.5% of samples showed increased expression. The Kruskal–Wallis test showed no significant correlation between TIM-3 expression and histopathological type (p = 0.452). It was concluded that TIM-3 expression is generally increased in nasopharyngeal carcinoma, but is not significantly associated with histopathological type. Further research is needed to evaluate the biological role and therapeutic potential of TIM-3 in this disease.
