Abstract

The Super Depo Sutorejo Surabaya (SDSS) Project was created to separate household waste into fractions, but its separation effect is unknown. This study assessed the significance of the project in sorting general waste into biodegradable, non-biodegradable, and assorted. The t-test compared the means of general and biodegradable waste (normally distributed). The non-biodegradable and assorted waste were not significantly distributed; therefore, the Wilcoxon Signed Ranks Test was used to compare their medians against general waste. The multivariate analysis compared the significance level of each waste fraction. Each statistical analysis showed that the SDSS significantly sorts the general waste. The p-values were (0.000) <0.05 for each type of waste fraction. Furthermore, the multivariate analysis showed that all variables were similar, and p-values (0.00) <0.05. The biodegradable waste was the most significant fraction (M = 176,715.9; SD = 57,990.8), followed by the assorted (M = 171,412.5; SD = 94,631.3), and non-biodegradable (M = 35,243.8; SD = 17,290.7). The results showed that the SDSS significantly segregates general waste into biodegradable, non-biodegradable, and assorted, therefore hypothesis (H1) is accepted. This study recommends the Government of Surabaya to maintain and expand this waste management project throughout the city alongside the improvement of the community participation program.

Abstract

Background: Nomophobia has emerged as a growing public health concern due to excessive smartphone dependence and its adverse effects on mental, physical, and social well-being. Although various interventions have been developed to address Nomophobia, evidence regarding the influence of educational background on Nomophobia and its associated health consequences remains limited. This study examined the association between educational background and nomophobia and its mental, physical, and social health outcomes. Methods: A cross-sectional study was conducted among 392 participants, purposively recruited from individuals with diploma- to doctoral-level educational attainment. Nomophobia was assessed using a modified version of the Nomophobia Questionnaire (NMP-Q), with responses converted from a 7-point to a 3-point Likert scale. Because the NMP-Q does not assess physical and social health outcomes, additional self-reported questionnaires were developed to measure these domains. Data were analyzed using multinomial logistic regression using IBM SPSS Statistics version 23, with statistical significance set at p < 0.05. Results: Nomophobia was observed across all educational levels (p < 0.001). Educational background was significantly associated with the mental (p = 0.017), physical (p = 0.001), and social (p = 0.014) health consequences of Nomophobia. Furthermore, higher educational attainment was significantly associated with a lower likelihood of experiencing Nomophobia and its related mental, physical, and social health problems (p < 0.001). Conclusion: Educational background was significantly associated with nomophobia and its mental, physical, and social health consequences. Individuals with higher educational attainment were less likely to experience Nomophobia and its adverse health outcomes. These findings highlight the importance of integrating digital health literacy and responsible smartphone-use education into health promotion strategies to reduce the burden of Nomophobia across diverse educational groups.
